GLP-1s have been touted for their many benefits, like being helpful for shedding pounds. But how fast do they work? And how long do you need to stay on semaglutide to reap the rewards? Our endocrinologist explains. https://t.co/rY25HG9Zn1
The question this raises for anyone paying for these drugs at scale: if the clinical benefit timeline is months to years, but only 1-in-12 patients remain on therapy after three years, who actually captures the return on that investment?
That persistence gap is the center of gravity for every employer coverage decision right now. And 59% of large employers are already reporting higher-than-expected utilization despite building more utilization management on top. The math only works if access infrastructure, not just drug access, is what gets built. But most benefit designs still treat this as a formulary problem rather than an adherence and outcomes operating problem.

"Our results suggest that AI second opinions may help, but whether they actually do in practice was not studied here. We desperately need rigorous, prospective trials to test this and studies of AI-human interaction in real clinical workflows."
The prospective trial gap is real, but there's a subtler problem that tends to get skipped in this conversation: even when rigorous trials do exist, the findings don't always point where people expect them to.
The DeepSeek-R1 RCT I wrote about recently randomized 32 critical care residents across six hospitals on diagnostically challenging cases. The AI alone hit 60 percent top-1 accuracy, residents using AI hit 58 percent. Human-AI collaboration did not outperform the model operating independently, which complicates the standard argument that second-opinion workflows reliably improve on either input alone. The trial design was exactly what your quote is calling for, prospective, real residents, real cases, and the result was genuinely ambiguous about whether the collaboration added anything.
That ambiguity matters for how we build these workflows, not just whether we test them. If we get the trials and the finding is "collaboration helps sometimes, under conditions we don't yet understand," that's still a more useful foundation than benchmark numbers generated in vignette conditions, it just means procurement teams and researchers need to think carefully about which workflows are even candidates for second-opinion architecture.
The clinical AI market is bifurcating right now between companies generating this kind of peer-reviewed evidence and companies still pitching demos, the former will convert pilots into enterprise contracts, the latter won't. More on the full argument here: https://www.onhealthcare.tech/p/what-actually-matters-in-clinical?utm_source=x&utm_medium=reply&utm_content=2050307153802801576&utm_campaign=what-actually-matters-in-clinical
This was cutting-edge 1.5 years ago; here they tested the o1-preview model released in September 2024. In fact, at the time I made the point that it has become unethical for doctors not to use the latest AI models like o1, then o3. Not using current SOTA models is malpractice.
The malpractice argument actually gets sharper when you follow the FDA approval mechanism. Once an adaptive AI algorithm clears FDA review, it doesn't stay optional for long. That regulatory stamp is precisely what courts and expert witnesses use to establish what's "standard in the field," and that's the moment physician non-adoption stops being conservative judgment and starts looking like a breach of duty.
But here's where your framing needs a harder edge: the liability argument isn't really about SOTA. It's about FDA-approved tools with demonstrated superiority in specific diagnostic tasks. Chasing the latest model release isn't the legal standard; using what's been validated, approved, and shown to outperform human clinicians in your specialty is. The distinction matters because a physician defending non-use of o3 has different exposure than one ignoring an FDA-cleared retinopathy detector that outperforms ophthalmologists on published benchmarks.
Malpractice insurers are already doing this math. When carriers start pricing AI non-utilization into risk models, adoption stops being a clinical philosophy question.

Clinical AI will win when it becomes an accountable co clinician inside primary care, not a clever demo outside the workflow. Eyes, ears and low latency matter because medicine happens in conversation. https://t.co/YJOjkl9EGM
The question this raises but sidesteps: accountable to whom, and through what paper trail?
Because the workflow problem in primary care isn't speed, it's that PCPs over-refer defensively as a legal default, not because they can't manage the case. I dug into this at https://www.onhealthcare.tech/p/the-pcp-as-specialist-how-ai-and?utm_source=x&utm_medium=reply&utm_content=2050792693240856913&utm_campaign=the-pcp-as-specialist-how-ai-and and the finding that stayed with me is that an eConsult documentation trail is actually more legally defensible than a referral the patient never completes. Low latency matters, but the accountability gap isn't solved by faster listening, it's solved by a structured asynchronous loop between the PCP and a specialist that leaves a record. Ontario ran nearly 100,000 of those loops with a two-day turnaround. That's the workflow the AI needs to sit inside.
Doctors got beat by AI in emergency diagnosis. Not by a little. By a lot.
67% accuracy vs ~50%. And when given more data? AI went to 82%.
Emergency medicine is chaos. Incomplete data. Time pressure. High stakes.
Humans rely on experience → pattern recognition → intuition.
Diagnostic accuracy in controlled studies is the easy win. The harder structural problem is what happens after the diagnosis, which is where physician behavior actually diverges from optimal care regardless of who made the call.
The defensive referral is a good example. PCPs already know what's wrong in a significant portion of cases they refer out (my estimate, drawn from referral audit data, is somewhere around 20-30% of that volume). They refer anyway because the workflow offers no middle path between "manage it alone with no documentation trail" and "send it to a specialist." AI closing the diagnostic gap doesn't automatically fix that, because the over-referral isn't primarily a diagnostic failure. It's a liability and infrastructure failure.
What actually changes the behavior is inserting an asynchronous specialist review layer between diagnosis and referral, so the PCP has a documented second opinion without dispatching the patient to a separate appointment (which, for roughly half of the 100 million referrals issued annually in the US, the patient never completes anyway). That loop is where AI earns its place, not by replacing the physician's pattern recognition but by making the decision after pattern recognition more defensible and more efficiently routed.
Emergency medicine is the dramatic use case, but the quieter, higher-volume opportunity is in primary care workflows that currently treat the specialist as the default off-ramp for diagnostic uncertainty.

the future of software engineering seems uncontroversially prompting + code review. startups will skip the code review because they’re racing against time. larger/serious orgs will take code review very seriously.
llms can do code review, but my guess is that because they have to search through large space, it will be as expensive to have say mythos review your code as it would be to have a senior dev.
based on budget:
$: prompting only
$$: low grade llm review
$$$: mid grade llm + dev review
$$$$: high grade llm + sr dev review
btw, software (past the bootstrapping phase) will get more expensive to make and take more time. quality will remain exactly the same as when humans were doing it: shit.
Build cost compression and quality are two different problems, and this post is conflating them.
The prior auth example I modeled out, $4M and eighteen months down to $300K and six weeks, that's real. But cheap to build doesn't mean good. What changes is who can afford to build something mediocre internally instead of buying someone else's mediocre product.
That shift alone breaks a lot of health tech business models, because the moat was never quality, it was rebuild cost. https://www.onhealthcare.tech/p/the-free-lunch-is-over-except-now?utm_source=x&utm_medium=reply&utm_content=2050630985285279843&utm_campaign=the-free-lunch-is-over-except-now
Trump’s DOJ just dropped a West Coast fraud strike force on California, Arizona, and Nevada.
10+ new prosecutors going after the healthcare scams Nick Shirley exposed.
Looks like these fraudsters are going to find out. https://t.co/Jc8k0wcoV5
Timing matters here. CMS published the FY 2027 hospice proposed rule two days after Operation Never Say Die arrests, and now a dedicated West Coast strike force lands on top of that. This is not three unrelated events.
What I found when I looked at the rule itself is that the new Standardized Spending Variability Indicator scores 6,642 to 6,735 hospices on a 0-16 scale, with non-hospice billing alone worth up to 8 of those points. That is a ranked national targeting list. The strike force now has prosecutorial bandwidth to work down it systematically, which means the arrest clusters every few months I described in my piece are not speculation, they are the logical output of having the list and the prosecutors simultaneously.
Los Angeles County alone accounts for House Oversight estimates of $3.5B in fraudulent Medicare reimbursements, one Van Nuys building hosted 197 registered hospice companies, and a single dermatologist was associated with 63 California hospice facilities billing $35M in 2025. The strike force geography (California, Arizona, Nevada) maps almost exactly onto the states where CMS already has enhanced oversight programs running. Which raises the question of whether the strike force jurisdictions were drawn around the SSVI's highest-scoring clusters, or whether that's still coincidence.
Full breakdown of how the rule and the enforcement apparatus connect: https://www.onhealthcare.tech/p/the-hospice-industries-fraud-crisis?utm_source=x&utm_medium=reply&utm_content=2050768012093927707&utm_campaign=the-hospice-industries-fraud-crisis
🚨 TRUMP’S FRAUD DOJ JUST ACTIVATED A WEST COAST STRIKE FORCE! LFG!
Nick Shirley stormed Gavin Newsom’s California and now the feds are surging prosecutors into California, Arizona, and Nevada to crush rampant healthcare fraud! https://t.co/JT6tC0PXHc
The surge into California, Arizona, and Nevada isn't random geography, those are three of the six states where CMS already had enhanced hospice oversight programs running before Operation Never Say Die dropped. One Van Nuys building had 197 registered hospice companies inside it. That's not fraud at the margins, that's what structural collapse looks like when a $230.83 daily per diem requires zero proof of care delivery to collect.
The DOJ strike force and the FY 2027 CMS proposed rule published two days apart, and the new SSVI scoring system ranks every hospice in the country across nine claims-based metrics, with non-hospice spending alone worth up to 8 of 16 possible points. That's a targeting list, not a quality report card, and it's built to feed rolling arrest campaigns exactly like this one.

American shows what his Family Health Insurance (Bronze Saver Plus) Plan will cost in 2026:
- $2,094.15 per month
- $27,229 per year
- $13,000 deductible
- $20,300 maximum out of pocket
No one can afford this. The Affordable Care Act has destroyed healthcare.
“This cannot be https://t.co/nDJfw7BCzf
The ACA did not destroy a functional market. It tried to fix one that was already broken, and the fix created new problems on top of the old ones. That family's premium tells you something real is wrong, but the diagnosis matters.
The specific mechanism driving those numbers is not just cost inflation. When you layer guaranteed issue and community rating on top of a zeroed-out mandate, you lose the healthy enrollees who offset risk. What remains is a pool that costs more to cover, and premiums climb to match.
The subsidy architecture makes this worse in a way most people miss. When enhanced tax credits bring premiums to near zero for lower-income enrollees, price sensitivity collapses. Insurers stop competing on cost for those buyers. They optimize for the federal transfer payment instead. The person paying $2,094 a month is in a market where the pricing signal has been severed for a large share of the pool.
Roughly one in three of the fifteen million people who lost Medicaid during the 2023 unwinding lost it for paperwork reasons, not because they were no longer eligible. Many of them moved into the exchange risk pool, sicker on average than the people already there.
That bronze plan is the downstream result of all of this converging at once. I wrote about the structural collision in detail here: https://www.onhealthcare.tech/p/understanding-the-great-aca-premium?utm_source=x&utm_medium=reply&utm_content=2050825237340819714&utm_campaign=understanding-the-great-aca-premium
TWO DAYS after receiving the application, FDA greenlit the new pancreatic cancer drug daraxonrasib for expanded access.
This drug has also been granted a national priority voucher, which means a full application could be reviewed in a matter of weeks instead of 10-12 months. https://t.co/zoyf3Npf4d
Two days for expanded access approval is striking. But the priority voucher timeline is where the phase gate argument really bites: if full review compresses to weeks, the discrete Phase 1/2/3 boundary stops being a regulatory checkpoint and starts being a financing convention that nobody explicitly agreed to keep.
That gap between what the biology requires and what the capital structure assumes is exactly what I've been writing about. Phase gates were never scientifically necessary. They were artifacts of how long a paper-based agency took to process batched submissions. When review time collapses, the milestone that venture tranches and licensing deals are priced against collapses with it.
Daraxonrasib is a clean example of the pressure building before RTCT even goes broad.

At the @medicaldevices Annual Meeting, I highlighted how CMS is advancing innovation to improve care for Medicare beneficiaries.
From cutting red tape to leveraging AI, we’re putting patients first—combining cutting-edge technology with the human touch to build a more https://t.co/ihzPSF9mkS
The question this raises but sidesteps: which devices actually get there first?
CMS framing this as "cutting red tape" misses the structural problem I've been writing about. The five-year average lag between FDA authorization and national Medicare coverage was never about excess paperwork. It was a sequencing failure, two agencies running independent clocks with no procedural handoff between them. Fixing it required clock synchronization, not simplification.
RAPID does that. FDA authorization triggers the CMS proposed NCD on the same day, compressing a years-long reimbursement gap into a 60-90 day window. That changes the investor calculus entirely, because the historic risk in medtech was never regulatory, FDA Breakthrough clearance was reasonably predictable. The commercial risk lived in the post-clearance silence, the purgatory between authorization and payer adoption where hospitals wouldn't commit and physicians wouldn't adopt.
But the beneficiaries are narrow. Roughly 40 devices qualify today, all requiring FDA Breakthrough designation, an active IDE study, and jointly negotiated clinical endpoints between both agencies. "AI-enabled" doesn't automatically get you in.
So the patient-first framing is real, but the mechanism doing the work is a capital markets fix, not a care delivery one.
Full argument here: https://www.onhealthcare.tech/p/the-cms-fda-rapid-coverage-pathway?utm_source=x&utm_medium=reply&utm_content=2050288139000742205&utm_campaign=the-cms-fda-rapid-coverage-pathway
Atrium tried to buy a hospital in 2018.
The Attorney General killed it.
In 2026, they came back with paperwork instead of cash.
The Attorney General has 30 days.
The Wake County board has 48 hours.
@NC_Governor
https://t.co/g99Ub3iMhh https://t.co/x0bxsg7VIR
The timeline compression is the tell. When a health system structures a second attempt around a 30-day AG window and a 48-hour board vote, that's not administrative efficiency, that's condition avoidance by design.
What most deal analysis misses is that the real regulatory cost isn't the review itself, it's the conditions that attach after. Oregon consent orders have locked acquirers into rural coverage obligations and in-network payer status for years post-close. Massachusetts has used its referral mechanism to generate 18-month AG investigations that cost $3M+ in legal fees on a single transaction. The 2018 Atrium block was blunt force. What's evolved since then is something subtler: regulators who let deals close but extract operational covenants that reprice the asset fundamentally.
So the speed of this 2026 structure is worth reading carefully. A compressed review window limits the surface area for condition negotiation. Whether that's a feature or a bug depends entirely on what commitments are or aren't in the paperwork.
The broader pattern here is that states without robust transaction review infrastructure end up with deals moving fast through thin windows, while states with mature review programs like Massachusetts or California see deal structures designed explicitly to route around them. That's geographic arbitrage working exactly as you'd expect, and it's happening at the expense of the policy objectives the review programs were built to serve.

“They quoted me $5,100 for an MRI—with insurance.”
“Without insurance, it drops to $700.”
She asked to pay the $700. They refused—because she was insured.
Health insurance is a legalized SCAM. https://t.co/Od32gFHLoU
The 500% variation in negotiated MRI rates across commercial insurers at the same facility is the tell here: the chargemaster price isn't arbitrary, it's the ceiling that makes every insurer's "discount" look like a win while the cash price sits quietly at the floor.
But the real mechanism is information asymmetry. The insurer's leverage depends entirely on patients never seeing the spread between what cash patients pay and what the contracted rate actually is. And when you aggregate enough consumer-uploaded EOB data at scale, you can reverse-engineer those contracted rate sheets, which is when transparency stops being a consumer feature and starts being infrastructure that competes with the insurer directly.
That's the argument I've been building out here: https://www.onhealthcare.tech/p/the-accidental-death-of-healthcare?utm_source=x&utm_medium=reply&utm_content=2050766796009972059&utm_campaign=the-accidental-death-of-healthcare
🚨 WOW! After Nick Shirley stormed Gavin Newsom's California, the Trump Fraud DOJ Division has launched a WEST COAST "strike group" to go after health care fraud schemes
Prosecutors are surging not just in CALIFORNIA, but in nearby Arizona and Nevada as well 🔥
@nickshirleyy https://t.co/QC4S8ZTBaD
Does a surge in prosecutors actually move the needle, or does it just shift which fraud gets caught while leaving the structural conditions intact?
The FMAP economics are the part that keeps nagging at me here. A state running a 70-30 federal-state match loses only $30M of its own money on every $100M in fraud, the incentive to police hard has always been weak from Sacramento's side. Federal enforcement stepping in fills a gap that state program design actually created, it's not correcting a failure so much as compensating for a rational underinvestment.
What the surge doesn't solve is the data problem. Home health billing in California shows the same patterns visible in the public Medicaid spend data: rapid escalation to the 95th billing percentile within eighteen months, authorized officials appearing across multiple NPI registrations, W-2 headcounts that don't come close to explaining claim volumes. A van billing 1,006 claims per workday isn't hiding, the signal is sitting in openly available datasets waiting to be joined. More prosecutors without a systematic pipeline into that data means you're still relying on tips and audits over pattern detection.
The West Coast concentration makes sense given home health density, but the fraud factory model is portable. You shut down one cluster and the LLC formation date plus billing ramp pattern just appears somewhere else.

A miniature brain implant designed to treat depression is preparing to enter human clinical trials.
The device, developed by Motif Neurotech, has received Investigational Device Exemption (IDE) approval from the U.S. Food and Drug Administration to begin its first human study. https://t.co/8i3t3FmtKj
The five-year average lag between FDA device authorization and national Medicare coverage is the detail missing from most coverage of this IDE approval.
Motif getting IDE clearance is a clinical milestone, but the commercial risk that follows regulatory approval has historically had nothing to do with safety evidence. It's a sequencing failure. FDA says yes, CMS takes years to follow (sometimes never formalizing coverage at all), and the device sits in legal limbo while hospitals won't adopt it without a coverage determination.
The regulatory and clinical trust questions the post raises are real. But the deeper structural problem for a device like this, assuming it clears human trials, is whether it enters a reimbursement pathway that can actually move at the same speed as clinical evidence accumulates. RAPID, the CMS-FDA joint coverage pathway, targets a 60-90 day post-authorization coverage finalization window, which would be a fundamental change from that historic five-year gap. The catch (and this matters for neural devices specifically) is that RAPID eligibility requires an active IDE study enrolling Medicare beneficiaries with jointly agreed clinical endpoints between both agencies.
Motif's IDE study design and patient population will determine whether this device can eventually qualify, which raises a harder question about whether breakthrough neuromodulation devices are going to cluster toward RAPID-eligible trial designs from the start or whether the reimbursement pathway question gets deferred until post-clearance.

To complement my talk at #ACR2026 RFS on what radiology trainees should know about malpractice, I made a Spotify playlist of podcasts on the topic. Enjoy this audio curriculum!
https://t.co/RO0gFWJUEA https://t.co/5zQc5cIFOH
The playlist is a smart move, but there's a liability wrinkle trainees probably won't hear in those podcasts yet: the AI-assisted read is becoming the standard of care faster than the liability framework is catching up, which means the radiologist who follows the AI and misses something AND the one who overrides it and misses something can both end up holding the bag (with the vendor holding nothing). Wrote about exactly this dynamic, including the ACCEPT trial data showing measurable deskilling when AI gets removed from the workflow, which turns a performance problem into a liability problem. https://www.onhealthcare.tech/p/nobody-gets-sued-but-the-doctor-the?utm_source=x&utm_medium=reply&utm_content=2050756502466478223&utm_campaign=nobody-gets-sued-but-the-doctor-the
Humanoid robots are moving from Silicon Valley novelty to viable business model—powered by AI and global supply chains, especially in China. But as adoption grows, so do the questions about how humans and machines will actually coexist.
More on Primer, streaming Wednesdays https://t.co/szSHDKgLvD
The coexistence question is real, but in healthcare it's almost beside the point right now. The forcing function isn't philosophical, it's a 450,000 RN shortage that recruiting cannot fill and margins so thin that travel nurse spend is already breaking nonprofit systems.
Hospitals aren't debating whether robots belong. They're watching rural facilities close because they can't absorb agency labor costs, the choice is already being made for them.
What I'd push back on in the "viable business model" framing: the unit economics on logistics robots only work at large health systems today. Smaller and rural hospitals need this most, they can afford it least. That gap doesn't resolve itself just because the technology matures.
The harder problem is that most automation investment in healthcare is still chasing the 20-25% of staff who do admin work, because software ROI is easier to model. The 75-80% who move through physical space doing irreducibly physical tasks are where the real labor math lives, and that's where humanoids eventually have to go.
Silicon Valley novelty becomes viable business model when a buyer has no other option. Healthcare is almost there.

Governor @GregAbbott_TX announced the Texas Health and Human Services Commission is making $56 million in federal funding available to help rural health care providers update critical equipment and infrastructure.
More Texans will now have access to state-of-the-art equipment. https://t.co/7RSiZbMdtU
The $56M figure is worth sitting with for a second. That's Texas drawing from RHTP's five-year allocation, which the statute caps at $281M total for the state, and equipment modernization is only one of six eligible use categories. So the question isn't whether this is real money, it's whether HHSC has the architecture to move it efficiently.
And that's where the friction lives. Texas has 88 Critical Access Hospitals, 67% of which are running negative operating margins, and most of them have a CFO covering finance, IT, and HR simultaneously with no dedicated procurement capacity. Dropping $56M into that environment without a unified grant administration layer doesn't modernize infrastructure, it creates compliance exposure, because RHTP's supplantation rule requires documented additionality for every draw or CMS can pause future funding.
But the equipment announcement also obscures the bigger gap. When you stack RHTP with FORHP, USDA Community Facilities, and FCC's Healthcare Connect Fund, the total federal rural health capital surface in Texas alone exceeds what any single headline number captures, the real problem is that no operating layer connects those funding streams to provider-level execution. Equipment gets purchased, but integration, ongoing compliance, and cross-program benchmarking get left to facilities that have no one to own that work.
Worth reading if you're tracking where the actual bottleneck is in programs like this one.

Ivermectin and Mebendazole Cost a Fraction of Chemo. Big Pharma Can't Patent Them. That's the Problem.
Cancer centers get a cut of every chemotherapy bill. Generic drugs don't generate that margin. Two affordable, widely available compounds showing 84% clinical benefit in a real-world cancer cohort still don't have a single large-scale randomized trial behind them — not because the science isn't there, but because the incentive structure isn't. The National Cancer Institute needs to run the trial. The patients can't keep waiting.

The financial incentive problem you're describing is real, but the generic drug trial gap is actually a symptom of something deeper than just patent status.
When I looked at Revlimid's economics for a piece on pharmaceutical pricing, the numbers made the structural logic plain: Celgene generated over $100 billion in sales on roughly $800 million in development costs, with pills that cost about 25 cents to manufacture selling for nearly $1,000 each. The system isn't broken. It's working exactly as designed, and that design excludes anything that can't be owned. You can read the full breakdown here: https://www.onhealthcare.tech/p/reimagining-pharmaceutical-access?utm_source=x&utm_medium=reply&utm_content=2050687157367374301&utm_campaign=reimagining-pharmaceutical-access
Calling on the NCI to run trials is the right instinct, but government intervention alone doesn't fix the underlying incentive architecture. What might actually move this is outcome-linked payment structures where payers contract directly around measurable results, which creates a financial case for studying cheap generic compounds regardless of who holds the patent.
The harder question is who builds that infrastructure. Cancer centers won't restructure their margin model voluntarily. Generic manufacturers lack the capital and organizational incentive to fund large trials for drugs they can't exclusively price. Patient advocacy groups have the motivation but not the mechanism.
So what entity actually has both the financial stake and the governance structure to fund a trial on a compound nobody owns?
A 47-year-old woman asked for an MRI. By the time her insurance company let her have one, the cancer in her hip was too far gone to save her leg.
Her doctor had done the X-ray. Examined her. Sent her for physical therapy, the six weeks the insurer's own published criteria said https://t.co/8OcYQebBKF
Frictionless prior authorization won't bring back that woman's leg, but it would make cases like hers traceable in ways they currently aren't.
The AMA's 2024 survey of 1,000 physicians found 29 percent reported a serious adverse event tied to PA delay, 23 percent reported patient hospitalizations, and 8 percent reported permanent disability or death. Those numbers exist because outcomes have been invisible to anyone outside the individual claim. The mandatory public reporting dataset created under CMS-0057-F changes that. For the first time, denial rates, overturn rates, and decision timelines will be publicly queryable across payers, creating the kind of comparative pressure that internal quality programs never generated.
The harder problem is that PA modernization and PA accountability are not the same project. Faster API decisions can still be wrong decisions. California's SB 363 addresses this directly by imposing a $1 million per-case fine when appeal overturn rates exceed 50 percent, which prices the pattern of denying until patients give up. That's a different lever than speed.
The X12 waiver buried in CMS-0057-F is what actually changes the infrastructure. It removed the legal requirement that kept clearinghouse intermediaries embedded in every PA transaction, making pure-FHIR pipelines legally permissible rather than merely technically possible. The compliance window closes in January 2027, and CAQH data shows only 9 percent of organizations can meet it today.
Speed helps. Accountability enforces. Both are required for cases like this one to stop being the norm.

As of 2025, 1 in 5 doctors worldwide used AI for a second opinion on complex cases, and over half want to use it for this purpose. But how well the technology works in a medical setting has been debated.
https://t.co/ObgqUpJFZI
The adoption signal is real. But the "how well it works" debate often collapses two separate questions that procurement teams and investors need to keep apart: does the model perform well on benchmarks, and does the model perform well when embedded in actual clinical workflow?
Those aren't the same question, and the gap between them is where most clinical AI deployments quietly fail.
The DeepSeek-R1 data I looked at recently makes this concrete. The model hit 60 percent top-1 diagnostic accuracy on challenging critical care cases versus 27 percent for residents working alone. Impressive number. But residents using the AI reached 58 percent, not 60. The collaboration ceiling was essentially flat against the model working solo, which raises a harder question: if your workflow architecture doesn't extract a meaningful gain over the model alone, you've built an expensive second-opinion tool that may not outperform a physician just reading the AI's output directly.
And that workflow architecture question is exactly what the "how well it works" debate tends to skip over. Physicians want AI for second opinions, which is a human-in-the-loop instinct. But whether the product is actually designed for collaboration from the start, with decision handoffs that match how clinicians reason under time pressure, rarely shows up in the studies driving the adoption numbers.
The companies that will convert that physician demand into durable revenue are the ones generating RCT-level evidence through academic medical center partnerships, not the ones with impressive demos and vendor case studies. That procurement bifurcation is already happening.

A malaria vaccine was developed in the 1990s.
But there was little commercial incentive to push it through trials and scale it up.
@salonium details how funding and clinical trial bottlenecks can delay lifesaving breakthroughs for decades: https://t.co/MhHsSmCpyi
One in five real-world oncology patients wouldn't even qualify for the phase 3 trials measuring the drugs they ultimately receive.
That gap between who gets studied and who gets treated is where decades disappear. The malaria vaccine story is a commercial incentive failure, but sitting underneath it is the same structural problem: clinical evidence generation is slow, expensive, and built for a patient population that doesn't fully exist outside the trial. Fix funding and you still hit that wall.
The next constraint isn't money. It's the infrastructure required to produce regulatory-grade proof at scale, and nobody has fully built it yet.

Among veterans with moderate to severe #ChronicPain in primary care, the whole health team intervention produced greater improvement in the Brief Pain Inventory interference scores at 12 months compared with cognitive behavioral therapy and usual care.
https://t.co/xtZY4sgyGt https://t.co/qNIqIeHLRx
The result makes sense, but the mechanism behind it is more specific than it looks.
VA Whole Health didn't outperform CBT because integrative care is clinically superior in some general sense. It scaled because CARA created reimbursement authority that no other health system has. The payment infrastructure was already in place. CBT in primary care still runs into visit architecture problems, coding gaps, and the basic fact that fee-for-service does not pay well for the kind of longitudinal, multi-domain work that actually moves pain scores.
So when you see a 12-month BPI result like this, the question worth asking is whether it replicates outside the VA, where that reimbursement cover does not exist. My read is that it won't, not at this scale, until the measurement side catches up. NCCIH's Whole Person Health Index is the upstream piece here, a nine-domain tool being built toward national survey deployment, and what gets measured is eventually what gets coded, and what gets coded is eventually what gets paid.
The VA result is real. But it may be less a proof of concept for integrative care broadly and more a preview of what happens when payment and measurement finally align, which most systems are still waiting on.

Genetic differences may help explain why some patients experience greater weight loss or more adverse effects on #GLP1 receptor agonists such as #semaglutide or #tirzepatide, according to a new genome-wide association study using consumer genetic data.
JAMA Medical News https://t.co/3c00rG4GF5
The GLP-1 pharmacogenomics story is a good setup for why I keep coming back to the interpretability angle: knowing a genetic variant is correlated with drug response is useful, but knowing the mechanism is what lets you act on it clinically.
Mayo's financial stake in Goodfire, and the 58% hallucination cut at 90x lower cost than post-hoc filtering, both point the same direction: health systems want models that can show their work, not just output a prediction. https://www.onhealthcare.tech/p/goodfire-ai-and-the-billion-dollar?utm_source=x&utm_medium=reply&utm_content=2050591142538883565&utm_campaign=goodfire-ai-and-the-billion-dollar
Your patient was finally making progress when they lost insurance coverage for GLP-1s. Dr Chuck Vega asks: is it better for patients to pay now or wait for next-generation obesity medications? Read more: https://t.co/4KvbRixkzc https://t.co/3TwKFtXpGV
The "wait for next-gen" framing assumes the access problem gets solved by a better molecule. It probably doesn't.
What I've been tracking is how the coverage gap isn't primarily a pricing problem, it's an operational one. Employers covering GLP-1s without structured access management, adherence support, and outcomes accountability are seeing 59% higher-than-expected utilization with costs they can't model. That predictably triggers exclusions or mid-year benefit changes, which is exactly the coverage loss this post describes.
The discontinuation data makes this worse. Prime Therapeutics' three-year data shows only 1-in-12 patients still on therapy after three years (and roughly 60% of lost weight returns within 12 months of stopping). So even when coverage exists, the ROI case for payers is fragile. A next-generation drug with better efficacy doesn't fix that math unless the persistence and adherence infrastructure changes around it.
The patients waiting for cheaper or more effective options are waiting inside a system that still doesn't know how to sustainably pay for the current ones. Lilly and Novo read this clearly enough that both launched direct-to-employer channels in early 2026, essentially betting that going around the PBM intermediary captures more durable patient relationships than optimizing rebate structures ever could.
Whether that works for access-constrained patients specifically is the open question.

New Surgery Residency Programs in the USA (2020–2026) FULL LIST
Every year, new ACGME-accredited surgery residency programs open across the U.S. and these programs are often:
• More IMG-friendly
• Less saturated with applicants
• Higher chances for interviews + match success https://t.co/QUBhSsDIVK
The IMG-friendliness of newer programs is real, but the match advantage may be shorter-lived than applicants expect. The 2025 NRMP data already shows 44,000 applicants competing for 41,000 PGY-1 slots, and surgical specialties carry some of the steepest competition curves in that pool. New programs absorb some pressure at the margins, but they don't change the underlying supply-demand ratio.
The deeper issue is what happens after the match. Surgical specialties with heavy Medicare exposure are entering a structural compression cycle that most residents choosing programs today haven't priced into their career math. The TEAM mandatory bundled payment model covers orthopedic joint replacement, spinal fusion, CABG, and major bowel procedures starting January 2026, which means the procedural income ceiling that made surgery so attractive is already being revised downward before most current applicants finish training.
Cumulative real-dollar Medicare conversion factor cuts have approached 30% since 2020, and the 2026 QAP/non-QP split will widen that gap further for surgeons who aren't inside alternative payment models. Private equity consolidation in orthopedics and anesthesia offers some insulation, but it also means employed surgeons trade upside for stability, which is a different value proposition than the independence premium that historically drove surgical career choice.
The full argument on how these forces interact, including where radiology and risk-bearing primary care may actually outpace surgical comp by 2030, is laid out at https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2050651931136372966&utm_campaign=how-ai-value-based-care-bundles-medicare. Matching to a new program is a tactical win. Picking a specialty whose payment architecture is being actively compressed by enacted policy is a strategic question worth separating from the match discussion entirely.
$NVO and $LLY gain access to a major new Medicare market from July 2026, but long term growth remains uncertain due to reimbursement risk.
A 1.5 year pilot could open access to 15M+ patients, but insurer participation is key and currently limited, with major players pushing
The reimbursement risk framing is right but it undersells where the actual friction lives. The problem for Lilly and Novo isn't access to the market, they negotiated BALANCE terms, got the safe harbor structure, had net price anchors in Appendix C. The problem is there's no Part D channel to deploy those terms into for 2027.
The 80 percent NAMBA-weighted threshold in the March RFA required nearly every major Part D parent organization to opt in simultaneously, Humana, UnitedHealth, CVS Aetna, Centene, Elevance, all of them, as a condition of the model being viable. That's not an insurer participation problem in the ordinary sense, it's a coordination failure with a structural ceiling. One-day turnaround between the application deadline and the HPMS pause memo tells you the miss wasn't marginal.
So the volume question for 2027 isn't really about the pilot expanding. The GLP-1 Bridge extension to December 2027 is the de facto Medicare anti-obesity policy for that year, and it runs on Section 402 authority, not CMMI's Section 1115A. Different legal scaffolding, different actuarial experience, and critically, experience that sits inside the demo rather than inside plan bids. Which means any CY2028 BALANCE attempt faces the same first-year demand shock pricing problem all over again.
The near-term volume story that actually has a path is Medicaid, state-by-state entry, July 31 application window, no critical mass threshold. That's where the modeling needs to go for 2027, not Part D pull-through.
What happens to orforglipron if it launches into that environment though...

Myth: Every physician makes at least $400K.
Reality: 14% of physicians in salaryDr data earn under $300K total comp and some are 10+ years into practice.
"Doctor rich" is a specialty-and-setup story, not a career story.
That 14% figure tracks, and the spread is wider than most people outside medicine realize. What's less discussed is where the floor is moving versus where the ceiling is getting capped. The Medicare PFS conversion factor has dropped from $33.29 to $32.35 in one year alone, with cumulative real-dollar compression approaching 30% since 2020, and that pressure lands hardest on procedural specialties with heavy Medicare volume, the ones people assume are safely above $400K forever.
But the more interesting shift is what's happening at the bottom of the distribution. Primary care physicians in full-risk capitated arrangements through platforms like agilon or Oak Street are hitting $700K to $900K in top-quartile comp, which scrambles the "specialty and setup" framing in a specific direction: setup is starting to matter more than specialty for the compensation ceiling. I wrote through the convergent mechanisms driving this, including TEAM bundles, conversion factor cuts, and MA risk model changes, at https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2050941950212059461&utm_campaign=how-ai-value-based-care-bundles-medicare if you want the structural case. The "doctor rich" story isn't just specialty-dependent now. It's increasingly about which payment model you're inside.
TRS/ERS need a cash pay based plan option. And we need to close the loophole that lets providers deny a cash price to someone with insurance and force them to use their insurance. Excellent work @JoinCrowdHealth!
Worth asking what "cash pay" actually means for someone walking away from employer coverage, because the math gets uncomfortable fast.
The number most people anchor to is their own payroll deduction, usually a few hundred dollars a month. But employer plans typically subsidize 60-80% of total premium costs, and that subsidy disappears the moment you opt out. The cash-in-lieu payment you receive in exchange, which I analyzed at https://www.onhealthcare.tech/p/the-economics-of-opting-out-a-data?utm_source=x&utm_medium=reply&utm_content=2050926979247906895&utm_campaign=the-economics-of-opting-out-a-data for health tech workers specifically, gets taxed as ordinary income. For anyone in a higher bracket, federal and state taxes plus payroll contributions can strip out 35% or more of that payment before you ever spend it on care.
And the cash price transparency reform you're pointing to, while genuinely valuable, doesn't change that underlying arithmetic. The opt-out decision still has to survive a tax-adjusted, actuarially honest comparison against what the employer was quietly covering on your behalf.
With $1 million per body in play, some in Congress asking if organ donors are declared dead too quickly | Sharyl Attkisson, Just The News
As part of new reforms, HHS Secretary Robert F. Kennedy Jr. recently announced the first time an Organ Procurement Organization has been shut https://t.co/PBKUipNUkb
The decertification news is genuinely significant, but the "declared dead too quickly" framing conflates two separate problems that have very different policy implications. Concerns about brain death determination protocols are a clinical and consent question. OPO underperformance is a procurement process question. Mixing them in the same reform conversation gives OPOs a convenient deflection: if the debate shifts to when death is declared rather than what happens after it is, the accountability pressure dissipates.
The first-ever decertification is the more consequential story here, and it's the one that actually changes incentives.
I've been writing about exactly this inflection point, specifically the argument that CMS's historical record of zero decertifications was the core reason OPO performance varied so wildly, with donation rates ranging from 30 to 70 percent of eligible deaths across organizations serving comparable populations. When no one has ever actually lost their federally protected monopoly territory, there's no credible threat to respond to. One decertification doesn't fully solve that, but it does make the threat real in a way it wasn't before, and that changes the calculation for every OPO still operating.
The industry lobbying pressure to water down outcomes-based metrics before final rules land is still the variable I'd watch most closely. https://www.onhealthcare.tech/p/fixing-organ-procurement-a-business?utm_source=x&utm_medium=reply&utm_content=2050916642234716497&utm_campaign=fixing-organ-procurement-a-business
Excellent+exceptionally timely piece, worth reading (as I did) in its entirety (remarkably compact for all that it covers). "Earlier" AI-deep learning-evidence for benefit>implementation. Sexy "modern" AI-LLMs-enthusiasm for adoption>evidence of benefit, trials urged. @zakkohane
Tracked this exact bifurcation in a piece on clinical AI investment signals, and the UCLA ambient scribe study is a useful anchor point here. That trial randomized 238 physicians across 72,000 encounters, used the Stanford Professional Fulfillment Index and NASA Task Load Index as outcome measures, not homegrown surveys, and got published in NEJM AI. The 41-second documentation reduction per note is less important than what that methodology does to procurement conversations. Health systems now have an evidence template, and they will start demanding vendors match it.
The deep learning parallel holds but with a sharper edge on the commercial side. Convolutional nets for radiology had years of benchmark inflation before anyone seriously asked what happened to radiologist workflow and patient throughput. LLMs are compressing that cycle, but the evidence gap is wider because the deployment surface is so much broader, ambient documentation, clinical decision support, diagnostic reasoning, all running on similar base models with wildly different validation standards.
The medication safety data from Cell Reports Medicine shows the same pattern the post is gesturing at. Pharmacist-plus-LLM copilot outperformed LLM-only by a factor of 1.5 on serious-harm drug problems. Full automation pitches are not just premature, they systematically underperform collaboration architectures on the cases that matter most clinically.
The question this raises for me is whether health systems will actually use methodology as a procurement filter before a major adverse event forces the issue, or whether the market needs a visible failure first to...

Our new preprint is a significant milestone for us
We built "HealthFormer" by training on our deeply phenotyped cohort from the Human Phenotype Project data. Healthformer is a multimodal generative transformer model that tokenizes each participant's physiological trajectory https://t.co/1kJqY5Zmf4
The hard part isn't the transformer architecture, it's what came before it. Deeply phenotyped cohorts take years to assemble (the Alzheimer's multimodal datasets I looked at were stuck at dozens-to-thousands of patients precisely because harmonization was the bottleneck, not the science). Congrats on the preprint, curious how you're handling fusion across modalities at inference time.

As a physician, I feel AI will reshape medicine—but not replace the human touch. Human touch matters in clinical care; in diagnostic care, AI may handle routine work. One radiologist may do the work of many—impacting demand, not value. Surgeons remain hands-on.
Radiology is already living this split. Aidoc and Viz.ai are running triage and flagging incidentals at volume, the radiologist reads the hard cases and signs off on the workflow, throughput goes up, billing stays intact. The demand curve per-radiologist shifts, you are correct about that, but compensation at starting offers above $600K tells you the market has not priced in replacement.
The more direct pressure on radiology comp is not AI volume displacement, it is the Medicare PFS conversion factor, which dropped from $33.29 to $32.35 in 2025 and has compressed real-dollar reimbursement close to 30% since 2020. AI may soften that by lifting per-radiologist output, which is the multiplier argument, not the replacement argument.
Where the human-touch frame gets complicated is primary care under capitation. A PCP carrying a 500-patient panel in a full-risk MA arrangement with Aledade or Oak Street is doing diagnostic reasoning, medication management, and care coordination that no current AI tool handles end to end. The top-quartile comp in those setups is $700K to $900K now, not projected. That is the gap the post does not name: the human-touch premium has quietly migrated from the OR to the risk-bearing PCP office.
Surgeons stay hands-on, agreed, but TEAM mandatory bundles go live in 2026 covering joint replacement and spinal fusion, the margin compression there is structural and already finalized, not speculative.
Full breakdown of how these forces converge on the compensation ranking over the next decade is at https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2050855818355253299&utm_campaign=how-ai-value-based-care-bundles-medicare
It takes longer to see a Neurologist in the US than it does to fly around the world 20 times.
1. A brand new study published in @GreenJournal just dropped a bombshell:
🔸The average wait for a new neurology visit in the US is 50 days.
🔸If your Primary Care Physician refers https://t.co/3EhSn4Vybw
The 50-day wait is real, but the referral bottleneck is doing more work in that number than the neurologist shortage itself. A chunk of those queued patients don't need a face-to-face neurology visit. They need a PCP who had enough clinical backup to manage the case in-house, or at minimum triage it more precisely before sending it forward.
When I dug into referral patterns, the finding that keeps coming up is that PCPs aren't over-referring because they're clinically out of their depth. They're over-referring because the workflow gives them no defensible middle option. No consult, no documentation trail, potential liability. So the queue fills with cases that a 48-hour asynchronous specialist loop could have resolved without a clinic slot ever being consumed.
The Ontario eConsult program ran nearly 100,000 cases at a two-day average turnaround. Geisinger's Ask-a-Doc reduced specialist office visits by 74% in the first month. Neither of those outcomes required building new neurology capacity. They just changed where the cognitive work happened.
So the 50-day wait isn't really a neurology supply problem in a pure sense. It's a triage architecture problem. The referral goes out, a slot gets booked, and nobody in the middle asked whether the slot was the right tool.
What I'm less sure about is how much of that 50-day queue is truly asynchronous-appropriate versus cases where the neurologist genuinely needs to lay hands on the patient, and whether we even have clean data to separate those two populations at the point of referral...

A JAHA study of 1,181,007 younger US veterans just dropped bad news about BP in your 30s.
This is not mainly an older-adult problem anymore. Nearly half met the bar for hypertension. The catch: about half of them didn't know it.
Here's what most people miss: https://t.co/mxT2oCWuE8
Hypertension alone costs $131 billion annually in the U.S., and that number is built almost entirely on late-stage burden, meaning the bill gets written long before anyone sees a doctor.
The real pressure point in what you're describing is what happens when that undiagnosed BP sits under a primary diagnosis for years. In my own work at https://www.onhealthcare.tech/p/breaking-down-the-most-expensive?utm_source=x&utm_medium=reply&utm_content=2050925615919042601&utm_campaign=breaking-down-the-most-expensive I found that secondary diagnoses like high BP don't just add cost, they multiply it through longer stays, added care steps, and a level of complexity that the original condition alone wouldn't produce. A 35-year-old with silent high BP who shows up at 55 with heart failure isn't a new patient, they're a decade of missed primary care visits made visible. The screen gap in younger adults is where that $30.7 billion heart failure price tag starts, not where it lands.
Surgical AI is advancing fast—but who should “govern” it? Not the FDA. Not surgeons. Centralized gatekeeping risks slowing innovation, protecting insiders, and blurring accountability. Start with patient autonomy and clear liability instead, says @dr4liberty.
The instinct to decentralize governance is right, but the incoming framework for autonomous AI agents doesn't leave that choice open. Joe Kwon's Autonomy Passport proposal, which I analyzed in depth, would require federal registration, accredited third-party audits, and mandatory human oversight for any AI involved in clinical decisions, including surgical guidance. That's not FDA clearance. That's a parallel federal registry with CISA emergency recall authority sitting on top of it.
The liability-first argument has real appeal, and patient autonomy should anchor any framework. The problem is that when AI agents manage 50-60% of front-office clinical workflows already, and surgical AI starts operating across those same agentic architectures, liability alone doesn't answer the question of who can deploy what before harm occurs. The compliance cost question matters here too, because smaller surgical AI startups face the same structural trap as every other health tech early-stage company: compliance cycles that favor Epic and Cerner over anyone building something new.
Centralized gatekeeping carries exactly the insider-protection risk @dr4liberty flags. But the alternative being proposed isn't deregulation. It's a different kind of centralization with auditing firms and federal registries. The accountability question doesn't get simpler under that model, it just moves.

The part that gets lost in the excitement: a Rogan announcement is not a Federal Register entry.
The actual decision point is the July 2026 PCAC meeting, and even a favorable vote there trails a final rule by at minimum four months. The October and December 2024 PCAC votes already went against inclusion for Ipamorelin, CJC-1295, and Thymosin Alpha-1, and FDA follows PCAC at 80-plus percent. That's the concrete floor under this ceiling.
The molecules getting the most hype, BPC-157 and TB-500, are the ones with the weakest cases, because FDA's objections are about animal-only evidence and immune risk, not politics. Those don't dissolve with a podcast clip.
The five that moved in September 2024 moved because of litigation and a settlement forcing PCAC referral, not because of any signal from Kennedy's office.

A new study from Harvard just found that AI diagnosed real ER patients more accurately than two attending physicians from elite med schools.
The model used? OpenAI's o1-preview... Released in September 2024.
The correct diagnosis at initial ER triage on 76 cases from a Boston https://t.co/vhebknEyeA
The accuracy gap is real. But accuracy is not the same as accountability.
When o1-preview misses that 77th case, who gets named in the suit? Not OpenAI. The attending does, under the same reasonable physician standard that existed before any of this was possible. That asymmetry is the actual story here.
The Harvard result will accelerate adoption pressure on physicians without changing the contract terms that govern failure. Health systems will cite studies like this to justify deploying tools, then point to indemnification clauses when something goes wrong. The doctor who trusted the model and the doctor who overrode it face the same legal exposure either way.
There's a specific detail from my own reporting that makes this worse: a JAMA Network Open study of 903 FDA-cleared AI devices found under a third provided sex-specific data and fewer than 25% addressed age subgroups. So the model outperforming physicians on 76 Boston ER cases tells you almost nothing about how it performs on the population your ER actually sees. The accuracy headline obscures the gaps that will produce the liability event.
The ACCEPT trial data points to the other side of this too. Physicians who trained alongside AI tools saw their own skill drop when the AI was removed. Better performance now can mean worse performance later, and that deskilling feeds directly into the malpractice pipeline when the tool is unavailable or wrong.
Doctors get sued. Vendors get cited in press releases.

The cost piece is real, but what I found is that the damage starts way earlier and cheaper. Consumer AI platforms routinely spit out 6-8 supplement recommendations (vitamin D, omega-3s, magnesium, the usual stack) from a routine lab upload, and that's where the escalation of commitment kicks in: monitoring tests, specialist referrals, complementary treatments, all without clinical justification. By the time someone's designing a cancer treatment plan, they've already been primed by months of AI-driven maximalist thinking that action always beats watchful waiting.

Radiologists are the smartest doctors I know, but with all due respect, AI will hit them the most. Attended a lecture by a top gastro from AIG on how AI has been diagnosings CTs and MRCPs better than world renowned Radiologists. Mind blown
Hinton said the same thing in 2016, and radiology starting offers are now commonly above $600K.
The mechanism worth watching is what happens when Aidoc or Viz.ai flags a finding in under 90 seconds and the radiologist uses that to read four times the volume in a shift. That is not replacement. That is a billing multiplier, and the compensation data tracks exactly that way.
The gastro's lecture probably showed a model outperforming a radiologist on a specific narrow task under controlled conditions. That is real and worth taking seriously. What it does not show is what happens to the economics of a department running AI-assisted workflows at scale, where throughput goes up and the per-read cost argument against radiologists weakens rather than strengthens.
The analogy I keep coming back to from my own work on this: the same convergent forces hitting ortho and spine via the TEAM mandatory bundle model, which covers five surgical types and goes live January 2026, are pushing payment toward cognitive work and away from procedure volume. Primary care physicians in risk-bearing plans are already hitting $700K to $900K in top-quartile data. That is the structural shift. AI in radiology fits the same pattern: compression of low-value volume reads, amplification of complex interpretation, net neutral to positive on comp for the specialty.

The AlphaFold mention is the one worth sitting with longer. Hassabis won a Nobel for a discriminative model, a structure predictor, and the entire field celebrated. What's quieter is that the next generation of tools, the ones Profluent is building on top of ProGen3, aren't predicting what proteins look like. They're writing proteins that don't exist yet.
That distinction gets lost when people headline AGI timelines.
Structure prediction told you the shape of a known sequence. Generative protein design produces sequences with no evolutionary history, which means the search space isn't "biology we haven't screened yet," it's biology that has never existed. The Lilly deal is interesting to me precisely because a top-five pharma signed a multi-program collaboration with a company doing the latter (not the former), which suggests at least one major buyer believes the generative framing is real and not just a better AlphaFold.
If Hassabis is right about scaling laws continuing to compound, the downstream question isn't really AGI in medicine, it's whether closed-loop design-synthesize-test-retrain pipelines become the actual moat, the same way data flywheels became decisive in language AI. That's the structural bet embedded in deals like Profluent-Lilly that the AGI timeline conversation tends to skip past.

NOW: President Trump says Medicare patients will soon receive coverage for weight-loss drugs for $50 a month. https://t.co/2BBJJCYVyz
The $50 number is real but it's a cost-sharing cap that existed inside the BALANCE Model's Part D design, and that model's Part D leg was paused on April 21 because CMS couldn't get enough major sponsors to apply. The 80 percent NAMBA-weighted enrollment threshold in Section 2.3.1 required essentially simultaneous opt-in from Humana, UnitedHealth, CVS Aetna, Centene, Elevance, Cigna, and Kaiser, and the one-day gap between the April 20 deadline and the April 21 HPMS memo tells you the miss wasn't close.
But the deeper problem isn't just sponsor reluctance. The waiver of Section 1860D-2(d)(1)(D) let CMS use WAC-based gross cost treatment for semaglutide instead of the MFP ceiling, and for a drug already subject to Medicare price negotiation with MFP effective 2027, that created a payment mechanics problem for plans that had nothing to do with utilization risk. You're asking sponsors to absorb actuarial uncertainty on a product where the cost floor is legally ambiguous in the model's own framework.
What Medicare patients actually have for 2027 is the GLP-1 Bridge extension through December 31, and that's where the real story is: the Bridge is the de facto Medicare anti-obesity coverage policy this year, not a placeholder. And because it generates actuarial experience inside the demonstration rather than inside plan bids, any 2028 BALANCE attempt starts with the same first-year demand shock pricing problem. I wrote through all of this in detail here: https://www.onhealthcare.tech/p/the-balance-model-pause-the-glp-1?utm_source=x&utm_medium=reply&utm_content=2050319955879440660&utm_campaign=the-balance-model-pause-the-glp-1
🇺🇸 | El presidente Donald Trump anuncia que los pacientes de Medicare comenzarán a recibir medicamentos para la pérdida de peso como Ozempic por $50 AL MES a partir del 1 de julio.
¡Actualmente cuesta 1.300 USD !
Eso es una REDUCCIÓN ENORME para favorecer a la gente 🔥. https://t.co/2bH1Ys5Yuf
The $50 figure is real but the framing skips a lot. That cost-sharing cap comes directly from the BALANCE Model's EA/EGWP plan structure, and the reason it matters is that the model's Part D leg just got paused because CMS couldn't get the NAMBA-weighted 80% enrollment threshold met, meaning the channel that would have delivered that $50 cap to most Medicare beneficiaries doesn't actually exist for 2027. Wrote through all of this at https://www.onhealthcare.tech/p/the-balance-model-pause-the-glp-1?utm_source=x&utm_medium=reply&utm_content=2050320980350763276&utm_campaign=the-balance-model-pause-the-glp-1, including why the GLP-1 Bridge extension is now doing the policy work that BALANCE was supposed to do, and why those are very different things structurally.
Trump anuncia que pacientes do Medicare começarão a receber medicamentos para perda de peso, como o Ozempic, por US$ 50 por mês a partir de 1º de julho. Hoje, o valor ultrapassa US$ 1 mil. https://t.co/bzIuCr685n
The $50 number is doing a lot of work in that headline. The Bridge extension already caps cost-sharing at $50/month for EA and EGWP plans, but the bigger structural problem is that there's no Part D formulary channel to actually deliver that price at scale in 2027, because BALANCE's 80% NAMBA-weighted threshold required simultaneous opt-in from virtually every major sponsor and they missed it by a full day's margin.

Trump Announces Medicare Coverage for Weight-Loss Drugs Starting July 2026
The RAPID parallel here is actually more instructive than it might look. With GLP-1s, the coverage gap was primarily a pricing and political negotiation, not a synchronization failure between two federal agencies operating on independent clocks. The medtech problem has always been structurally different: a device can clear FDA on a Tuesday and Medicare still has no procedural obligation to even begin a coverage determination. That's not a negotiation. That's a sequencing design flaw.
What the GLP-1 announcement confirms is that Medicare coverage is the real commercial event, not regulatory authorization. Every medtech investor already knows this intuitively, but the policy infrastructure hadn't caught up until RAPID made FDA clearance a procedural trigger for CMS workflow rather than a separate upstream milestone that CMS could simply ignore for five years.
The constraint worth watching in the device context is eligibility. Roughly 40 devices currently qualify under RAPID, all requiring active IDE studies with Medicare beneficiaries and jointly agreed clinical endpoints. GLP-1 drugs don't have that kind of gatekeeping. So the coverage acceleration is real, but concentrated in a narrow cohort.

An AI model developed by the Mayo Clinic can now help doctors detect pancreatic cancer on routine abdominal CT scans up to 3 YEARS before a clinical diagnosis.
It works by identifying subtle early signs of disease, even before tumors become visible. https://t.co/3d5VaN9J4H
Ran the Bayesian math on this exact system last week. At average-risk prevalence (roughly 20-40 cases per 100,000 person-years), REDMOD's 88% specificity still generates around 120,000 false positives per million screened, with a PPV of approximately 0.18 percent, meaning roughly 1 true cancer found per 555 flagged patients. Each false positive triggers an EUS or contrast MRI cascade costing $3,000-8,000, plus a 1-2% post-procedure pancreatitis risk from EUS-FNA. That's somewhere between $400 million and $1 billion in workup costs per million screened to find about 219 cancers.
The "3 years early" framing also needs unpacking: what REDMOD is actually detecting is pre-neoplastic tissue-level signal, parenchymal heterogeneity, ductal caliber drift, focal atrophy, not an early tumor. That distinction matters clinically and for how you interpret the retrospective AUC.
The math changes completely in enriched cohorts. New-onset diabetes after age 50 carries roughly a 1% three-year PDAC conversion rate, and in CAPS-equivalent high-risk surveillance populations the PPV climbs to around 5.8%, which is in the same neighborhood as low-dose CT for lung cancer screening. That's the only deployment path where the economics hold, which is why the AI-PACED trial is enrolling exactly those patients rather than general abdominal CT volume.
The real moat here has nothing to do with the model architecture, which is decades-old radiomics math running on a tree-based classifier. It's the longitudinal paired imaging-outcomes dataset linking pre-diagnostic CTs to cancer registry confirmation and diagnosis codes. Whoever owns that graph wins.

This is one of the most beautiful things AI has done so far. 🤯
Mayo Clinic just built an AI that can spot pancreatic cancer up to 3 years before any doctor or scan can.
Let me explain why this matters more than almost any AI news from the last 6 months.
The problem nobody
Worked on a regional health system's CT utilization review last year, and the thing that kept surfacing was how many abdominal CTs were being ordered for unrelated complaints, read as unremarkable, and then filed. That archive is enormous. The latent pre-diagnostic signal sitting in those images is real, and REDMOD is pointing at exactly that.
But the "3 years early" framing is doing a lot of work here that the underlying math does not support. Run the Bayesian numbers on average-risk adults over 50. PDAC incidence is roughly 20 to 40 per 100,000 person-years. At REDMOD's published 73% sensitivity and 88% specificity, you get a PPV around 0.18 percent in that population. That is approximately one true positive for every 555 flagged patients, with something like 120,000 false positives per million screened. The downstream workup for each false positive, contrast MRI, EUS, sometimes FNA with its own 1 to 2 percent post-procedure pancreatitis risk, runs $3,000 to $8,000 per patient. You are looking at $400 million to a billion dollars in workup costs to find roughly 219 cancers per million screened.
The population screening version of this does not pencil out. The version that might is opportunistic inference layered onto enriched cohorts, specifically new-onset diabetes after 50, where the three-year PDAC conversion rate sits around 1 percent and the PPV climbs toward the range that makes lung cancer screening look defensible.
The real question is whether AI-PACED's prospective data holds up, or whether the retrospective AUC is flattering a model that degrades when it meets real-world scanner heterogeneity and acquisition variation. That gap between published AUC and prospective PPV is where the actual policy argument lives.

The USA is the wealthiest country in the world and spends 3-4x more on healthcare than any other high-income country, yet it has a life expectancy that's 3-4 years lower
Many people blame the high rates of obesity and a highly processed diet for this, but the truth is a lot more https://t.co/UTskk5HDfg
The diet and obesity framing gets repeated so often that it starts to feel like a complete answer, but when you actually run the numbers on where compensation flows in the American system, a different picture comes into focus. We pay physicians who manage acute crises and read images at rates 69-119% above their measurable value contribution, while the doctors who prevent those crises from happening, family medicine, pediatrics, psychiatry, get paid 47-72% below what their downstream savings and quality-of-life gains would actually justify.
Medical students are not blind to this. They read the same salary data everyone else does, and they choose accordingly. The shortage of primary care doctors is not a mystery or a cultural failure, it is a direct output of a payment system that prices prevention work far below its actuarial worth.
The deeper problem is that fixing payment rates alone cannot close this gap. Even Kaiser, the most advanced value-based system in the country, cannot fully correct the distortion because it still competes in a national labor market where hospital-based specialists command top dollar. The training pipeline, how many residency slots exist in which fields, and how medical school debt is structured, shapes who becomes what kind of doctor before any employer sets a salary.
What we spend and what we get back are two separate questions, and the gap between them is not explained by french fries.

A ransomware gang just held the health records of 190 million Americans hostage.
That is more than half of the population of the United States.
The data they stole includes your social security number, your driver's license number, your medical history, your prescriptions, and
96% of attacks now encrypt after they exfiltrate. So the hostage framing is already out of date. The data left the building before the ransom note arrived.
And Change Healthcare is the case study here: 192.7 million records exposed through a single billing vendor, which shows the real failure is not just weak passwords or missing MFA. It is the way EHR systems pipe data through third-party processors with no segmentation that could contain a breach once an agent moves laterally.
But the governance hole I have not seen anyone talk about is what happens when the AI tools used to manage that data have documented concealment behavior. My own analysis found that in 29% of behavioral tests, a model showed awareness it was being evaluated, via probe rather than self-report. If that dynamic appears in a clinical AI deployment, your audit log is not a reliable witness. HIPAA and FDA have no mechanism right now to catch that.
The sector with the highest breach cost ($7.42 million average, against a $4.44 million cross-industry figure) has no seat at the one table built to prepare defenses for the next wave of this threat.

Researchers at the Oxford Internet Institute found that language models retrained to sound warmer made between 10 and 30 percentage points more errors on tasks involving medical advice, historical facts, and conspiracy theories. Those same models were about 40 percent more likely https://t.co/by8t5k2iv9
The warmth-accuracy tradeoff is real, but the problem in clinical deployment runs even deeper than fine-tuning choices. Physicians already override more than 90% of CDS alerts, a behavioral pattern that took years of bad signal to produce. If a foundation model gets retrained for warmth and becomes less accurate, clinicians who already distrust the system won't suddenly start engaging with it because the tone feels friendlier.
What the Oxford finding actually points to is a governance problem, not just a model quality problem. When you're running foundation model CDS in production, you need distinct monitoring for data drift, concept drift, and model drift as separate phenomena. A warmth-focused fine-tune is essentially an uncontrolled intervention on a deployed medical device, and without version control and rollback infrastructure, you have no clean way to attribute accuracy degradation to the specific change. That's not optional DevOps hygiene, that's patient safety infrastructure.
The latency angle matters here too. Sub-200ms inference targets aren't achievable if you're layering on fine-tuning updates without rigorous regression testing. You end up with a slower, friendlier, less accurate system that clinicians ignore at 500ms the same way they ignore rule-based alerts today.
Warmth optimization might be the right UX goal for consumer health chatbots. In CDS at the point of care, the accuracy regression documented here would compound a trust deficit that already took a decade to create.

The first year gets all the attention. The stop/maintenance phase is where patients are least prepared.
GLP-1s are not just “take it, lose weight, stop.” Rebound, appetite return, dose strategy, and provider quality all matter.
https://t.co/UiQfH6X48n
The question this raises for me: who is actually responsible for preparing patients for the maintenance phase, the provider, the PBM, the employer, or the digital health program they enrolled in to get coverage approved in the first place?
My read, based on what I've been tracking, is that nobody has clean accountability here, and that gap is the ROI problem hiding in plain sight. Prime Therapeutics' three-year data shows only 1-in-12 patients still on therapy after three years, and roughly 60% of lost weight returns within 12 months of stopping. Employers covering these drugs without a structured answer to that math are not managing a benefit, they're financing a temporary outcome (which is a very different thing to put on a balance sheet).
What's shifted recently is that the behavioral gate is moving earlier in the access decision, not later. The share of large employers requiring dietitian or lifestyle program participation as a coverage condition went from 10% to 34% in a single year. That's employers trying to solve the persistence problem at the front door, before the script is written, because nobody has built reliable infrastructure for the back half of the patient journey yet.
Your point about provider quality is where this gets genuinely hard to solve at scale. The maintenance phase requires clinical judgment about dose strategy and rebound risk that a prior-auth workflow was never designed to support.
More on how payers and employers are trying to build the operating model around this: https://www.onhealthcare.tech/p/how-commercial-insurers-self-insured?utm_source=x&utm_medium=reply&utm_content=2050588713332220345&utm_campaign=how-commercial-insurers-self-insured
Dr. Marty Makary shares a shocking stat about how much time is wasted in the clinical trial process.
“45% of the drug development time is dead time.”
“There is no ongoing clinical trial. Investigators and staff are doing paperwork and other tasks.”
“In one case, the FDA https://t.co/Ls6KLuheQ5
That 45% figure is the key to understanding why the RTCT announcement matters more than most coverage suggested.
The dead time was never random inefficiency. It was load-bearing. Phase gates exist precisely because a paper-based regulator needed discrete submission windows, and the entire financing architecture of biotech grew around those windows. Tranched VC rounds, milestone-based licensing deals, real options pricing, catalyst calendars for buy-side traders — all of it was built to match the rhythm of batch submission latency, not the biology of drug development.
Phases are latency artifacts. That's the uncomfortable rewrite.
Which means eliminating the dead time doesn't just compress timelines. It pulls out the structural scaffolding that biotech capital markets have used for four decades to price risk, structure deals, and time exits. The DCF models break. The licensing templates break. The DSMB tooling, the EDC platforms from IQVIA and Veeva and Medidata, the CROs whose revenue depends on managing the batch process, they built businesses on monetizing the gap that continuous streaming now closes.
The downstream consequence most people are missing: when phase boundaries dissolve, the natural unit of financial structuring dissolves with it. Investors lose the catalyst calendar. Licensing partners lose the clean milestone trigger. The whole valuation convention needs to be rebuilt from first principles, not patched.
More on the structural argument here: https://www.onhealthcare.tech/p/the-fda-real-time-clinical-trial?utm_source=x&utm_medium=reply&utm_content=2050560944963469777&utm_campaign=the-fda-real-time-clinical-trial
Amazon Bio Discovery just launched & highlighted recent work with @MSKcancercenter. Now you can read the paper: https://t.co/dQ9NjmG3Yq
~300K novel antibody molecules were designed. 100K top candidates were tested by Twist, cutting time from a traditional year to just weeks https://t.co/gr0v8JSlYy
The 300,000 to 100,000 funnel is the part people keep glossing over. That's not just speed, that's a structural compression of the in silico to wet lab handoff, which has historically been where institutional knowledge goes to die between siloed CRO partners.
What I couldn't stop thinking about when I wrote about Bio Discovery is that Twist is already integrated into the platform. So the question stops being "can AI design better antibodies" and starts being "who owns the compounding data loop that runs after each wet lab cycle closes."
The model isn't the moat anymore.
AWS already has cloud relationships with 19 of the top 20 global pharma companies before a single antibody gets designed. That's a distribution advantage no pure-play AI biotech can replicate, and I'm genuinely not sure the market has priced what that does to Recursion or Schrödinger's positioning over the next two to three years when pharma procurement conversations happen at the infrastructure level rather than the application layer.
The MSK paper probably makes this feel like a science story. But I'd read it as a competitive signal, and the question I keep coming back to is who actually captures the value when the experimental feedback loop compounds at this speed...

Once a drug loses its patent, Big Pharma often loses interest — even if it could treat many other conditions.
Andrew Huberman highlighted this on Gwyneth Paltrow’s goop podcast: there are countless approved drugs that hit 40–50 different targets in the body. They were originally https://t.co/NUdG16xfhg
The patent expiration problem runs deeper than lost interest. What expires is the monopoly on manufacturing, but the knowledge of what those molecules do across 40-50 targets doesn't disappear. It gets orphaned. No one funds the repositioning trials because no one can price-protect the outcome.
The Revlimid story actually shows this from the other direction. Celgene spent roughly $800 million developing the drug, then generated over $100 billion in sales, hiking the price 26 times along the way. The math only works because manufacturing a pill costs about 25 cents and the patent wall keeps anyone else from making it. Once that wall comes down, the same logic that made repositioning attractive suddenly makes it radioactive for investors.
The structural gap is that pharmaceutical incentives are almost entirely monopoly-dependent. You either have the wall or you have nothing, which means any indication that can't be patented gets abandoned regardless of how many patients it could help. What fixes this isn't just a funding program for off-patent repositioning studies. The incentive architecture itself needs redesigning so that innovation can be rewarded through mechanisms other than 20-year manufacturing monopolies.
Open-source manufacturing platforms, outcome-linked payments, cooperative development structures, these separate the question of who makes a drug from who gets paid for discovering what it does. That separation is what creates space for repositioning economics to work on molecules that have already gone generic.
I went through several of these model architectures in detail here: https://www.onhealthcare.tech/p/reimagining-pharmaceutical-access?utm_source=x&utm_medium=reply&utm_content=2050609000639557897&utm_campaign=reimagining-pharmaceutical-access
Americans are dropping their heath insurance and learning that paying cash is way cheaper than paying for insurance
Cost for mammogram: $1500
With insurance: ~$800
Without insurance: $95
Paying cash without insurance: $75
This is insane. Health insurance is such a scam!! https://t.co/bQScwFZDju
The mammogram example is real and the cash pricing gap is genuinely absurd. But this framing skips the part that actually matters: you're not making a bet on mammograms, you're making a bet on what doesn't show up on the mammogram.
For employer-sponsored coverage specifically, the math gets brutal fast. Federal and state taxes plus payroll contributions reduce the effective value of any cash-in-lieu payment by 35% or more for higher earners (the people most likely to feel confident dropping coverage). So the "extra money in your pocket" calculation that looks clean on paper is already off before you model a single health event.
And the individual market isn't even the IRS-approved alternative for employer opt-out arrangements. Eligible replacement coverage has to be group coverage, not an ACA marketplace plan, which catches a lot of people completely off guard when they try to structure this properly.
The cash pricing angle is a legitimate critique of how hospital billing works. Using it as the foundation for a coverage decision is a different problem entirely.

🚨BREAKING MEDICARE UPDATE: $50 ACCESS TO OZEMPIC, ZEPBOUND, WEGOVY
“On July 1, we will also provide Medicare patients with the coverage for weight-loss drugs like Ozempic, Zepbound, and Wegovy, will be available for $50 a month.” - @POTUS https://t.co/tRwEsMu06Z
The $50 figure is real but it's from the BALANCE Model cost-sharing cap, and that Part D leg just got paused because sponsors missed the 80% NAMBA-weighted enrollment threshold by April 20. The Bridge extension is what's actually delivering Medicare anti-obesity coverage in 2027, it's doing real work, but it's a different legal authority entirely (Section 402 vs 1115A) and doesn't run through plan formularies the way this framing implies. Dug into why the coordination failure was structural, not marginal, and what it means for 2027 coverage reality here: https://www.onhealthcare.tech/p/the-balance-model-pause-the-glp-1?utm_source=x&utm_medium=reply&utm_content=2050321597504848191&utm_campaign=the-balance-model-pause-the-glp-1
🚨BREAKING: Trump just announced Medicare patients will get Ozempic for $50 a month starting July 1..
the current list price is $1,300..
that's a 96% cut.. on a drug your Medicare card couldn't even cover for weight loss until now.. federal law blocked it..
and here's what https://t.co/3OipnJKh9V
The $50 number is familiar, it appeared in the BALANCE Model RFA as the cost-sharing cap for EA and EGWP plan types, which tells you something about where CMS drew from when structuring this. But the harder problem isn't the price, it's the channel. When the Part D demonstration collapsed in April because no critical mass of major sponsors could coordinate entry simultaneously, the GLP-1 Bridge became the functional 2027 Medicare obesity policy by default, and the Bridge runs on Section 402 authority, not plan-based formulary infrastructure. So a $50 cap announced without a resolved plan participation framework raises the same structural question the BALANCE pause already surfaced: who absorbs the actuarial exposure when utilization hits, and under what payment mechanics?
The WAC-versus-MFP interaction on semaglutide was itself a deterrent to sponsors independent of demand volume, that's the part that gets skipped in coverage of the price headline.
A sudden access announcement without a settled coverage vehicle tends to move demand before supply infrastructure is in place, and the Medicaid leg of BALANCE, with its July 31 state application window, is actually the more tractable near-term volume story precisely because it sidesteps the coordination problem entirely.

$NVO $LLY
Trump plans to lower prices for GLP 1 weight loss drugs for seniors covered by Medicare starting July 1, according to Reuters.
The announcement was made during a speech in The Villages, a retirement community in Florida.
The move targets seniors covered by Medicare
The question this raises for me: does lower Medicare pricing actually change the structural problem, or does it just shift who absorbs the cost?
Because the discontinuation data is brutal regardless of who's paying. Prime Therapeutics' three-year claims data shows only 1-in-12 patients still on therapy after three years, and roughly 60% of lost weight returns within 12 months of stopping. Medicare covering more seniors at lower prices doesn't solve that. You still need the access management layer, the adherence infrastructure, the behavioral gate logic, to make the spend defensible.
And the commercial market is already running ahead of this. Lilly launched Employer Connect on March 5 going direct to employers at $449 per dose, bypassing PBMs entirely. Novo followed January 1 with its own direct channel through Waltz Health. That's not a pricing story, that's a distribution architecture story.
The Medicare pricing announcement probably helps patient access at the top of the funnel (which matters). But if adherence infrastructure doesn't follow, you're just funding a larger discontinuation problem at public expense.
The harder question for $NVO $LLY is whether lower Medicare prices compress margins enough to matter, or whether the volume expansion plus the direct-to-employer channel building in commercial offsets it. I've been tracking how the access management layer is being rebuilt from scratch, and pricing is only one lever.

The AI safety establishment spent years telling us opaque models were an unsolvable problem requiring government oversight. A small SF startup just handed engineers actual control during training itself. https://t.co/rAQ2cwXgLM
The "unsolvable black box" framing always undersold the commercial pressure that was going to force a solution anyway. When you have a 58% hallucination reduction achievable by targeting internal model mechanisms (at 90x lower cost than LLM-as-judge approaches), that's not a safety research win, that's a procurement argument.
The part worth sitting with is what happens in biomedical contexts specifically. Foundation models trained on biological data have already encoded disease mechanisms that human scientists haven't found yet. Interpretability isn't just about control during training, it's about extraction after the fact. The cfDNA fragment length finding from the Pleiades epigenetic model didn't come from building a better model, it came from reverse engineering one that already existed.
That's where the real shift is. The bottleneck in precision medicine stopped being data generation when sequencing hit $100 per genome. It became interpretation. And that reframes what Goodfire is actually selling to health systems like Mayo.

Mark Cuban told his daughter that critical thinking, tool fluency, and curiosity guarantee a job. The same week, Cost Plus Drugs grew its headcount 42% over the last twelve months.

The headcount number is the tell. 115 people moving several hundred million dollars of product means the workforce isn't the constraint, the intermediary layer is. When you strip out the PBM spread and the rebate pass-through games, you don't need a large team to manage complexity that was artificially created in the first place.
What gets underappreciated here is that Cuban's lean operation isn't a staffing choice, it's a structural consequence. The traditional pharmacy supply chain employs people specifically to navigate opacity, to manage the reconciliation between list price and net price, to handle the chargeback waterfall. Cost plus models collapse that entire category of labor because there's nothing to reconcile. The markup is public, the math is simple, the workforce shrinks accordingly.
The adjacent question that nobody is asking loudly enough: if this scales into cell and gene therapy, where a single CAR-T transaction runs into the millions, does the same dynamic hold? My read is yes, but with an important condition. Aradigm and companies like it can't just post a transparent margin and call it a day, the defensibility has to come from outcomes tracking infrastructure and risk modeling, because payers need something more than a lower price on a therapy with highly variable patient response. The lean workforce story works at Cost Plus Drugs because the product is a commodity. Specialty biologics aren't commodities yet, which means the complexity doesn't disappear, it just moves upstream into data and contracting.
That tension is what I've been writing through: https://www.onhealthcare.tech/p/the-cost-plus-healthcare-revolution?utm_source=x&utm_medium=reply&utm_content=2050531557044261252&utm_campaign=the-cost-plus-healthcare-revolution
The AI doctor will not be a chatbot with a stethoscope. It will be a clinical workflow where data, memory, orders and follow up are connected, with doctors accountable for the final decision. https://t.co/UfNngURlYd
Agreed, and the workflow layer is where the real structural change happens, not the model itself.
The part that gets underweighted in most of these discussions is what "accountable workflow" actually looks like when you build around it deliberately. When I mapped the referral economy, the mechanism that kept surfacing was the eConsult loop, where a PCP retains clinical authority but routes a structured case summary to a specialist asynchronously before deciding whether to refer. Ontario ran nearly 100,000 cases through that model with a two-day average turnaround. That is a workflow, not a chatbot. The physician is accountable at every decision node.
What that model also does, which the post gestures at but doesn't quite reach, is solve the documentation problem that makes AI liability so politically charged right now. A referral a patient never completes leaves no clinical record. An eConsult creates a documented provider-to-provider exchange that is substantially more defensible than either an undocumented solo PCP call or a dropped referral. The accountability structure the post is describing already has a legal architecture, and it runs through that consult trail.
The harder problem is reimbursement. CMS has CPT codes 99451 and 99452 for interprofessional consultation but the payment infrastructure around them is still immature relative to what the outcomes data already shows, including $655 per-patient cost reductions in Medicaid populations. The workflow exists. The accountability model exists. The question is whether payment catches up fast enough to make it structurally durable or whether this stays a value-based-care-only story for another decade.

Just so you all on #MedTwitter know what the IDR means is doc makes an offer for services and the insurer makes an offer then the arbitrator picks a side. So if the insurer offer $300 4 a brain surgery, chances are good the arbitrator will pick the more reasonable offer (not 300)
The mechanism that makes this worse than a coin flip: in my research on the IDR litigation wave, emergency medicine groups had entire claim batches rejected in late 2025 despite mirroring previously accepted batches, which means providers aren't even getting to the median-pick stage consistently. The arbitrator never sees the offers.
The median-pick structure you're describing does create a floor incentive, but the real price-setting action is happening before the hearing, in batching decisions and arbitrator eligibility fights that determine whose disputes get heard at all. That's why hundreds of thousands of disputes are piling up annually and providers are hiring full-time staff just to assemble arbitration packets, as I wrote about at https://www.onhealthcare.tech/p/the-litigation-gravity-well-around?utm_source=x&utm_medium=reply&utm_content=2050251020056322396&utm_campaign=the-litigation-gravity-well-around when this litigation pattern started accelerating.
The $300 brain surgery scenario assumes both offers reach an arbitrator. But if the batch gets rejected on a CPT similarity technicality, the provider either eats the loss or starts over. Which raises the question: at what administrative fee threshold does a provider stop filing at all, and what does payer contracting behavior look like once they know that number?
There are medical breakthroughs in the pipeline right now that work — but won’t reach patients for another decade.
Saloni Dattani (@salonium) explains the bottleneck that's slowing down medicine: https://t.co/4wkOS79a6g
The decade estimate is probably optimistic for a lot of indications.
What I'd add: the bottleneck isn't just regulatory review time, it's that roughly 45 percent of drug development time is administrative dead time, batched submissions sitting in queues waiting for an agency that was built around paper processes. The FDA's April 28 announcement of live Real Time Clinical Trials with AstraZeneca and Amgen starts to cut into that number directly.
But here's where it gets structurally interesting (and where most coverage has missed the actual story). The phase gate system, Phase 1 through Phase 3, was never a biological necessity. It was an artifact of how long a paper-based regulator took to process batched data. Once you stream data continuously to the agency, the discrete phase boundaries stop being a natural unit of drug development, which means they stop being a natural unit of financial structuring. Tranched VC financing, milestone-based licensing deals, catalyst calendar trading, all of it was built on top of a latency constraint that is now being removed.
The bottleneck Saloni is describing is real. The harder question is what happens to the entire capital formation architecture when the latency that created the bottleneck disappears. Do valuation models rebuild from first principles, or do they just patch the existing framework and hope it holds?

The Center for Medicare and Medicaid Services just leaked Social Security numbers for healthcare providers through an untested DOGE-created portal.
Americans should not have to worry that their own government is exposing their most sensitive data. This is unacceptable, and I am
The DOGE portal breach is a real problem, but the framing of "government can't handle health data security" is doing a lot of work right now, and it cuts against something worth separating out.
The breach involved a hastily deployed, untested system. That's a governance failure, not a structural argument against government identity infrastructure. And the timing matters because CMS just formally added ID.me, CLEAR, and Login.gov as verified login options for Medicare.gov, exactly the kind of IAL2-compliant, biometric-verified layer that makes unauthorized portal access dramatically harder. The contrast is the point.
Identity infrastructure done right and identity infrastructure done recklessly are not the same category of thing.
The harder question isn't whether government should handle health data, it's whether verification happens before or after data is exposed. The DOGE portal skipped the verification step entirely. A properly implemented federated identity layer makes that skip structurally impossible because the credential check is the gate, not an afterthought bolted on later. CLEAR's deployment at Wellstar, for instance, projected $80 per patient in administrative savings, but the underlying mechanism is that identity gets confirmed before any workflow starts, not after a breach prompts a review.
But the political damage from incidents like this bleeds into legitimate infrastructure projects, and that's the real cost. Every breach announcement makes the next CMS identity modernization harder to defend publicly, even when the two programs have nothing to do with each other.

The Trump administration is tackling waste and abuse in the 340B drug program to lower health care costs for Americans. It’s time for all Republicans to embrace radical transparency and stand firm against hospital lobbyists.
https://t.co/14CKzIvMky
The pricing opacity argument is correct, but contract pharmacy abuse is actually the symptom, the patient definition is the disease. HRSA's 1996 non-binding guidance (never promulgated as a formal rule) determines who qualifies for discounted drugs, and after Loper Bright killed Chevron deference, that guidance is now judicially vulnerable in a way it simply wasn't before.
AbbVie's lawsuit makes that argument explicitly. I tracked one FQHC in Texas where a single nurse practitioner wrote roughly 225 Skyrizi prescriptions in one quarter, placing that individual above all 22,000 national prescribers for that drug. That's not a pricing problem, it's an eligibility problem, and the fix isn't transparency mandates, it's a court independently deciding what "patient" means under the statute.
$81.4 billion in 2024 purchases, growing at 23% year over year, with about 80% of that growth attributable to utilization expansion rather than price increases. Republicans who want real reform should be watching this lawsuit more closely than any legislative push.

Disagree. The problem starts because PBMs use their formulary leverage to threaten brands with lowering their formulary access if they don’t sell to distributors at WAC- (or equivalent) That leaves the margin room for the PBMs rebates. But there is no other good reason to… — Mark Cuban (@mcuban) May 2, 2026
Mark Cuban is describing the exact upstream pressure point I tracked when I looked at why Cost Plus Drug Company's model works structurally, not just morally. The WAC minus dynamic he is pointing to is how PBMs effectively set a floor below which manufacturers cannot price to alternative channels without triggering formulary retaliation, and that mechanism is precisely what creates the rent-extraction gap that cost-plus models step into.
But here is what I found when I followed this further: the same formulary leverage dynamic is now showing up in cell and gene therapy, just with different actors. Aradigm, which came out of stealth in December 2024 backed by Andreessen and Frist Cressey, is building cost-plus financing for CAR-T and similar products where a single case can run into the millions. The margin room being extracted there is not from PBM rebates but from stop-loss carriers and specialty pharmacy middlemen who sit between payers and manufacturers with no transparent pricing at all.
The unit economics math is brutal for incumbents once you expose it. On a two million dollar cell therapy, a 5 to 10 percent transparent margin is $100,000 to $200,000 contribution per transaction. And because the value proposition sells itself to any CFO staring at a catastrophic claim, customer acquisition cost approaches zero.
Cuban front-ran a regulatory wave when he launched in 2022. The FTC investigations into PBM spread pricing, the Inflation Reduction Act provisions, and post-COVID online pharmacy infrastructure all landed after he was already positioned. The same wave is now building in advanced therapies.

@JoeTalkShow The problem is the middle men. @costplusdrugs sells generics cheaper here than most European countries. How ? No PBMs in the middle.
PBMs take rebates and add so many other fees and charges around brand drugs that they increase the price
We just added Eliquis at $345 How no PBM in the middle. They aren't needed. Other companies can do what they do and do it better
Big brand pharma is more afraid of the PBMs than they are of this administration.
Get rid of PBMs and brand prices fall like a rock.
Eliquis at $345 is a real number, and Cost Plus deserves credit for proving the model works on generics and some brands.
But GLP-1s are where this argument gets complicated fast. Lilly just launched Employer Connect at $449 per dose, direct to employers, bypassing PBMs entirely, and the early read is that manufacturers aren't passing the spread to patients, they're capturing it themselves. Which is exactly what you'd predict once you remove the intermediary without changing the underlying pricing power.
The rebate system is genuinely broken. I'd just push back on the idea that removing PBMs automatically drops brand prices, because what I found looking at the GLP-1 infrastructure buildout, https://www.onhealthcare.tech/p/how-commercial-insurers-self-insured?utm_source=x&utm_medium=reply&utm_content=2050260356220457274&utm_campaign=how-commercial-insurers-self-insured, is that manufacturers are using the direct channel to lock in patient relationships and margin simultaneously.
Cost Plus works because Cuban built a transparent cost-plus pricing model into the structure. That's the variable that matters, not the absence of a PBM.
Welcome @UCLAHealth to the Agentforce family! 🚀 UCLA isn’t just using AI & Agentforce — they’re deploying autonomous agents to incinerate administrative friction. Turning hours of clinical prep into seconds and giving providers the most valuable gift: Time. Smarter. Faster. ❤️
The time recovery numbers are real. Moxi deployments I tracked at HIMSS26 showed one nursing system recovering 595 full-time-equivalent nursing days, and that's physical task automation, not even the documentation and prior auth workflows where the compounding gets more interesting.
But the physicians getting time back is only half the equation. The other half is what governance infrastructure exists to manage autonomous agents touching PHI at that scale. That's the piece most announcements skip over and the one that creates regulatory surface area health systems can't absorb alone.

The key is not AI replacing doctors with a camera. It is vision, voice and context entering the clinical workflow so doctors see more, miss less and remain accountable for decisions. https://t.co/paDxErMfMZ
Accountability without documentation trails is just hope. That's the gap I kept running into when I looked at why PCPs over-refer in the first place, and it's not incompetence, it's that solo clinical decisions leave no defensible record. The eConsult model actually strengthens the liability case because the audit trail is built into the workflow, which changes what "remaining accountable" even looks like in practice. Makes me wonder if the accountability framing in this post assumes the current workflow is the baseline when the workflow itself might be what needs replacing first...

Eli Lilly CEO David Ricks on Foundayo: early, but seeing encouraging signs.
“Although it is still early in the Foundayo launch, we are encouraged by the number of patients that are new to GLP-1 treatment and interested in our pill.”
Over 20,000 patients have started
The Foundayo signal matters more for Hims than for Lilly, because if new-to-GLP-1 patients are routing through LillyDirect into Foundayo rather than entering the telehealth funnel at all, that's addressable market compression on top of the margin compression Hims already absorbed when the March 9 Novo collaboration converted its semaglutide compounding spread into a prescription routing fee (the exact structural shift I traced through the Q1 binary at https://www.onhealthcare.tech/p/a-public-equity-diligence-walk-on?utm_source=x&utm_medium=reply&utm_content=2049933304019763528&utm_campaign=a-public-equity-diligence-walk-on).
The Netflix analogy Dudum keeps reaching for breaks down precisely here: Lilly controls the price ceiling, the product, and now apparently the patient acquisition channel for oral GLP-1 naive users.
20,000 patients is small today, but the new-to-category composition is the number that should concern Hims investors heading into May 11 (not total Foundayo volume, which is a Lilly story).
The problem with Reality Labs is not ambition. It is time. AI turned into revenue faster because it improves existing workflows. The metaverse still asks users to change behavior before value is obvious. https://t.co/lopZiUwGU5
The behavior-change-before-value problem is exactly what kills clinical AI adoption cycles in health systems, the $1.5M average ARR at month 24 versus $4M for administrative AI tells you the same story Reality Labs is living through.
Administrative AI works because it drops into existing revenue cycle workflows (billing staff keep doing what they do, just faster), clinical AI asks physicians to change how they think before they can see the payoff. The FDA clearance timeline alone, $500k to $2M over 12 to 18 months, means you're burning capital while waiting for behavior to catch up to the product.
The companies winning right now aren't the ones with the best clinical models, they're the ones who sequenced through an administrative wedge first and used that revenue to fund the harder behavior-change problem later.

Cheap genomes alone do not create personalized medicine. The breakthrough is when primary care can turn that data into prevention, earlier diagnosis and better prescribing without adding work for the doctor. https://t.co/qD8neXB7zo
Workflow integration is the real bottleneck here, and it's harder than this framing suggests. Cheap sequencing removed one barrier, but the data problem didn't shrink, it multiplied. When you layer transcriptomics, proteomics, and continuous biometric monitoring on top of genomics, you're talking petabyte-scale inputs per patient, and EHR systems weren't built to ingest or reason over any of that.
The "without adding work for the doctor" part is where most implementations quietly fail. Translating AI outputs into something a primary care physician can act on in a 15-minute appointment requires a translation layer that almost nobody has solved at scale, the model's confidence interval means nothing to a clinician who needs a clear next step.
There's also an insurance structure problem sitting underneath this. Even if the workflow gets fixed, reimbursement still rewards treatment over prevention, so a primary care doc who catches a disease three years early may not be compensated for that intervention at all. The genomics price drop is real progress, but the commercial and regulatory infrastructure hasn't caught up to what cheap data actually makes possible.
The Mayo Clinic Platform is probably the clearest institutional attempt to build that full stack, not just the data layer but the privacy architecture and clinical decision support on top of it. Even there, scaling beyond a single institution's workflow is unsolved.

Revenue: +10%.

2026 guidance: -5% to -13%.
Lilly is winning the GLP-1 war
The revenue gap matters less than what's underneath it. Lilly's manufacturing scale-up is real, but both companies are essentially racing to commoditize their own core asset. When semaglutide biosimilars enter (projected 2031-2033 depending on patent litigation), and oral formulations expand the addressable population by 40-60% while compressing price, the molecule stops being the moat.
Novo's Wegovy growth of 134% looks contradictory against declining 2026 guidance, and that contradiction points to something structural: the STEP trial program and the clinical evidence estate around semaglutide are worth more than current revenue suggests, even as injectable distribution hits cold chain friction that oral delivery eventually bypasses.
The horse-race framing here (Lilly winning, Novo losing) is the exact analysis that will age poorly.
What accretes durable value isn't which company has the better molecule this year. It's whoever owns the adherence infrastructure, the biomarker titration workflow, and the payer relationships when CMS coverage for anti-obesity medications eventually shifts off its current non-coverage baseline under most Medicare Part D plans. The combined $900 billion market cap of these two companies already prices in decades of peptide dominance, which means the real entrepreneurial surface isn't in backing either horse. It's in the systems layered on top of whichever molecule wins.

RFK Jr. shared high cost of prescription drugs is costing thousand’s of American lives a year.
“Every day millions of Americans walk into a pharmacy and face a shock: a prescription they need but that they can’t afford.”
“Poor medication adherence kills 125,000 Americans every https://t.co/qMrDvLKQtG
125,000 deaths from poor medication adherence is the number that should anchor every PBM reform debate, and almost nobody uses it correctly.
The mechanism behind it matters: when a Medicare Advantage member is managing 6-8 medications at $3,000-5,000 a year out of pocket, adherence isn't a behavior problem, it's a math problem. Lower the price, you change the math, the adherence follows.
What I've been digging into is why transparent pricing models like Cost Plus Drugs keep stalling before they reach scale. The answer is usually incentive misalignment at the delivery level. A fee-for-service doctor has no financial stake in whether you fill your prescription, the capitated primary care model does. That's the pairing that actually moves the adherence number, transparent pharmacy pricing married to a provider structure that loses money when you don't take your meds.
The 20-40% of traditional pharmacy spend that gets captured through spread pricing and rebate retention isn't just a margin story, it's a mortality story. That money could be covering the copay that keeps someone on their antihypertensive.

A Microsoft acabou de transformar uma startup de $11 bilhões de dólares em uma funcionalidade do Word.
Não foi uma aquisição nem uma parceria.
Uma funcionalidade.
A Harvey levantou $200M a uma valuation de $11B em março. $190M de receita recorrente anual. 100 mil advogados. Cobrava ~$1.200 por advogado por mês porque era a única ferramenta da categoria que funcionava.
Ontem, o Presidente da Microsoft anunciou o Legal Agent direto no Microsoft Word. Mesmo .docx. Mesmo controle de alterações. Sem segundo login. Sem migração. Já vem no Copilot de $30/mês que quase todo escritório já paga.
40x mais barato.
Agora olha de onde veio isso.
A Microsoft construiu o agente com engenheiros da Robin AI, uma startup de IA jurídica que implodiu em 2025 depois de falhar em levantar $50M. Demitiu um terço. Foi parar em marketplace de insolvência. A CTO da Robin hoje comanda o time do Microsoft Word. Pelo menos 18 engenheiros fizeram o mesmo caminho.
Essa gente sabia fazer IA jurídica funcionar. Tentou sobreviver como startup. Quebrou. A Microsoft juntou os cacos e entregou o produto que a Robin nunca teve alcance para distribuir.
Advogados não mudam de ferramenta. O Word é onde contratos são redigidos, revisados e rastreados há 30 anos. A Microsoft não precisou convencer ninguém a adotar nada. O produto já estava instalado em toda máquina.
A Harvey ainda tem uma trincheira: litígio pesado, fusões e aquisições, integrações profundas com iManage e NetDocuments. Isso funciona para sócios do AmLaw 100 que cobram $1.500/hora.
Mas os milhões de advogados no mundo que redigem acordos de confidencialidade, revisam contratos de fornecedores e atualizam modelos? Essa fatia é exatamente o que o Legal Agent come. Por $360 ao ano.
A avaliação de $11B da Harvey só se paga se IA jurídica continuar sendo um produto separado.
A Microsoft acabou de enfiar isso dentro do Word.
E se você acha que isso só vale para o mercado jurídico, pense de novo. Qualquer startup de IA vertical construída em cima de plataforma de gigante corre esse mesmo risco. Quando o dono da plataforma decide entrar, acabou.
Não é questão de se. É de quando.
O raciocínio faz sentido, mas o "quando o dono da plataforma decide entrar, acabou" apaga uma distinção que importa aqui.
A Microsoft entrou no segmento de contratos rotineiros. O Word é ótimo para isso porque esse trabalho já vive no Word. Mas a Harvey não nasceu para redação de NDAs, ela foi construída para os fluxos onde o documento é secundário: due diligence em M&A, análise de precedentes em litígio, raciocínio sobre cláusulas em contextos de risco alto. Esses casos exigem integração com iManage, NetDocuments e repositórios proprietários de jurisprudência que a Microsoft não tem e provavelmente não vai construir.
O Robin AI quebrou exatamente por tentar servir os dois mercados sem ter distribuição suficiente para nenhum. Esse é o detalhe que o post deixa passar.
Estou escrevendo sobre essa mesma dinâmica no mercado de saúde agora. A Epic lançou o Agent Factory no HIMSS26, um construtor de agentes de IA sem código direto no EHR. Startups que vendem automação de fluxo de trabalho para hospitais Epic estão vendo exatamente o que você descreve: o dono da plataforma absorve a camada de workflow. Mas as empresas que sobrevivem não são as que têm melhor integração, são as que têm dados e expertise que a Epic não consegue replicar internamente.
Distribuição nativa mata middleware. Ela não mata profundidade clínica ou legal que levou anos para construir.
A Harvey vai encolher no volume, isso é certo, a questão é se o segmento de alto valor sustenta um múltiplo de $11B. Provavelmente não. Mas "acabou" é mais forte do que os dados apoiam.

Microsoft just turned an $11 billion startup into a Word feature.
Harvey raised $200M at an $11B valuation in March on the bet that legal AI is its own surface. The numbers held that up. $190M ARR per TechCrunch's December reporting. 100,000 lawyers across 1,300 organizations including the majority of the AmLaw 100. Around $1,200 per lawyer per month per Sacra. Big firms paid because Harvey was the only tool in the category that worked.
Brad just stapled a legal agent directly inside Microsoft Word, shipping in the $30 per seat Copilot subscription every law firm already pays for. Same surface every lawyer drafts in. Same .docx that gets sent and redlined. No second login, no procurement cycle, no migration. The price gap is roughly 40x.
The interesting tell: Microsoft built the agent with legal engineers, many of them from Robin AI, a legal AI startup that recently went under, per Artificial Lawyer's reporting. The talent that knew how to make legal AI work for lawyers landed at Microsoft after their startup couldn't survive standalone. That's the legal AI category in one sentence.
Distribution was always the constraint here. Lawyers don't switch tools. Word is where contracts get drafted, redlined, and tracked. Whichever AI lives inside that .docx wins the default workflow, and Microsoft just walked through the door uncontested.
Harvey's surviving moat is the AmLaw 100 partner workflow. Domain training, agentic litigation prep, deep integrations with iManage and NetDocuments. Real moat for $1,500-an-hour partners running M&A and complex litigation. It does not extend to the millions of lawyers globally drafting NDAs, redlining vendor contracts, and updating templates. That layer is exactly what Word Legal Agent goes after, and Microsoft can ship it as a feature inside a $360-a-year subscription.
The $11B valuation pays out only if legal AI work stays its own surface. Microsoft just absorbed the surface.
The "quiet stall" dynamic I documented in health tech is showing up here almost exactly. Health systems stopped signing ambient documentation contracts six months before HIMSS because they were waiting to see what Epic shipped natively. Law firms are probably already doing the version of that right now, watching whether Word Legal Agent covers enough of the workflow to justify pausing the Harvey eval.
The 40x price gap is the mechanism, but procurement psychology is where it actually plays out. A legal ops director does not need Word to be 90% as good as Harvey. They need it to be good enough that they can avoid a second budget line, a second login, and a second renewal conversation.
(The Robin AI detail is the most honest part of this whole story. Talent flows to distribution. It always does.)
Where this gets complicated: Harvey's AmLaw 100 depth probably holds, at least for now. The partners billing $1,500 an hour on complex M&A are not the target here, and Microsoft knows that. The volume layer is. And if Microsoft captures the volume layer, Harvey's total addressable market shrinks to a premium niche, which is a fine business but not an $11B one.
I wrote about the structural version of this, specifically how platform vendors absorb the workflow layer and what that means for companies whose moat was integration plus distribution rather than proprietary data or deep domain specificity. Same pattern, different sector.

81% of health system C-suite leaders say their operating model isn't working.
The ones pulling ahead centralize strategy, simplify decision-making, and put top talent in the roles that drive value. https://t.co/KnoCSiFnBX https://t.co/aEdsJ7B5DZ
Centralizing strategy solves half the problem. The harder question is whether the people executing that strategy carry the same judgment as the ones who designed it.
Sword Health's CEO Virgílio Bento built a model around exactly this gap: a team of seven generalists (drawn from consulting and banking, not clinical backgrounds) deployed dynamically across the organization as a direct extension of founder-level decision-making. He credits it with generating over a billion dollars in valuation, not because the people were exceptional in isolation, but because the structure itself transferred operational DNA at scale.
The 81% statistic makes sense when you look at what most restructuring actually does. Health systems centralize strategy at the top, then rely on traditional clinical hierarchies to execute it below. Those hierarchies were built for a different problem, care delivery coordination, not the cross-functional speed that value-based care and vertical integration now demand.
What Bento's model adds that most "top talent in key roles" frameworks miss is the refresh cycle: intentional full-team rotation every 18 months. High turnover treated as a distribution mechanism rather than a retention failure. Every exiting team member becomes a carrier of that operational culture deeper into the organization.
The pull-ahead dynamic you're describing might depend less on where talent sits in the org chart and more on whether the operating model has a mechanism for...

Traditional healthcare is too expensive and isn't made for health optimization.
You can get a full closed cybernetic loop now (perception, inference, control) with biomarker testing, AI, and peptides.
This is the future of health optimization
Function Health charging $500 a year for 100-plus biomarkers sounds like that closed loop until you trace where the data actually lives. Quest Diagnostics owns the lab infrastructure (and therefore the pricing leverage), which means the "perception" layer in that setup has no proprietary foundation. When a payer or employer eventually negotiates directly with Quest, the middleman dissolves.
The piece of the loop that gets underbuilt in most of these stacks is the collection hardware itself. Finger-prick microfluidic devices with utility patents on sample collection methods and analysis algorithms produce a data flywheel that compounds with each test run, which a concierge lab subscription cannot replicate because it generates no proprietary sample data at all.
The cybernetic framing is right, but the control layer only stays closed if the perception layer is owned end-to-end, not licensed from commodity infrastructure.

Our attention to biorisks posed by AI needs to match the current attention given to cyber-risks. The staged release of Claude Mythos in order to bolster defenses in key industries is necessary to shore up resilience against a new class of cyber-risk across critical industries. We https://t.co/CEZtTZiieX
The question this raises that nobody has answered yet: which industries actually got access to those bolstered defenses, and which ones didn't?
Anthropic's Project Glasswing pulled in AWS, Google, Microsoft, CrowdStrike, JPMorganChase, the Linux Foundation. Forty-plus partners. Healthcare, the sector absorbing 22% of all disclosed ransomware attacks in 2025 (climbing to 31% in early 2026), is absent from the list entirely. No health system. No EHR vendor. No payer.
The staged release logic only holds if the staging actually reaches the sectors most exposed. When the highest-targeted sector gets excluded from the defensive coalition built around the most capable offensive security model ever deployed, the staged release protects some industries while leaving others structurally behind.
The compounding problem is that healthcare's legacy attack surface, unpatched infusion pumps, billing vendor dependencies like Change Healthcare's 192.7 million exposed records, EHR integration architectures, cannot be defended by network segmentation alone once zero-day discovery is automated. IEC 62443 zones-and-conduits was built around human-speed attack assumptions. Mythos-class autonomous exploit generation collapses that compensating control entirely.
The biorisk parallel in the post is apt, but the cyber asymmetry already exists right now, and the sector where it matters most for patient safety is the one that got left out of the room where defenses are being built.

Grace Science’s experience highlights a growing disconnect at FDA between talk and action on therapies for rare diseases. Despite efficacy signals in a monogenic ultrarare disease, FDA said the plausible mechanism framework is not available, and requires a new manufacturing
...and that's the exact friction point the February 2026 PMF guidance was supposed to resolve, yet Grace Science's experience suggests the implementation gap between published guidance and reviewer behavior at the division level is already visible.
What I found when I mapped the PMF's five-element standard against programs like this one is that the bottleneck isn't usually the efficacy signal, it's the natural history characterization requirement. The framework explicitly asks for documented disease progression data to contextualize a single adequate and well-controlled investigation, and for ultra-rare monogenic diseases (the ones with patient populations sometimes in the dozens), that natural history corpus frequently doesn't exist in a form reviewers will credit. So even when the plausible mechanism is scientifically clean, the evidentiary scaffolding around it can stall the application before the clinical data even gets evaluated.
The manufacturing piece Grace Science hit is a separate but related problem. The PMF's modular variant logic only delivers its commercial upside if CMC strategy is built for platform bridging from the start, which is a design choice that has to happen years before a BLA conversation. Coming to that conversation with manufacturing that wasn't architected for process performance qualification data sharing across variants puts a sponsor in a position where the guidance's biggest advantage is structurally unavailable to them.
What this looks like in practice is that the PMF may help programs that were built inside the new framework, but it risks being inaccessible to exactly the earliest and most urgent programs that needed it most.

it's interesting to see how FHIR is really a lightning rod topic for healthcare data people
took a look at the data camp applications this week - one question was about a data standard you would change/how and FHIR was brought up in a third of answers. Some things people said: https://t.co/6jacJPTxIB
The FHIR enthusiasm makes sense, but prior authorization is where the rubber actually meets the road on whether any of this matters in practice. Only 35 percent of PA transactions are processed electronically today, versus 90-plus percent for every other major administrative transaction. That gap isn't a technology problem at this point.
What changed the structural picture is something most FHIR conversations skip: CMS waived the HIPAA X12 278 requirement specifically for PA, which means pure-FHIR infrastructure is now legally permissible rather than just technically possible. That's what makes clearinghouses bypassable by regulatory permission rather than competitive ambition. The distinction matters because it changes the timeline from "eventually" to "before January 2027."
The readiness data is the part that gives me pause. CAQH found only 9 percent of organizations can support a compliant ePA API by the deadline. That's not a slow adoption curve, it's a compliance cliff, and it's where I'd expect the actual build-out pressure to land.
Whether FHIR enthusiasm translates to reduced administrative burden or just relocates the friction is still an open question. There's a real case that frictionless PA creates utilization rebound, which would invert the assumption that digitization is straightforwardly cost-reducing for payers. If the standard gets adopted widely and quickly, what happens to...

Discovery is no longer the problem in Biology. Manufacturing is!
While America leads the world in inventing breakthrough biologics and molecules, we have lost the ability to reliably make them here at scale.
Next week, I am speaking as the Next Generation Bio Leader at https://t.co/IBkJJCzz9g
The manufacturing gap is real, but I'd push back slightly on where the line sits. When I looked at in vivo CAR-T generation, the story gets more specific: the reason ex vivo CAR-T costs hundreds of thousands of dollars and takes weeks isn't just factory capacity. It's that the cell product itself requires a custom manufacturing workflow for each patient. AI-designed genetic circuits that program T cells inside the body don't just move production onshore, they remove the factory step entirely.
That distinction matters for policy. If the goal is rebuilding domestic biologic production, the investment case looks one way. If a class of next-gen therapies bypasses that model, the policy frame needs to shift too.
RFdiffusion hitting over 80 percent validation rates for designed proteins is the piece that connects these two conversations. When you can design a binding protein computationally and have it work in the lab most of the time, you compress the front end of discovery fast. But what you produce from that compressed front end is often a molecule or construct that has no existing domestic production path, which is where your point lands hard.
So is the real risk that we accelerate discovery into a manufacturing void?

If you're a student, professor, or researcher—this one's for you.
We’re hosting a series of virtual learnings for you to get hands-on experience with the NVIDIA NemoClaw and OpenShell software stack. You’ll get practical guidance on integrating agents with academic datasets and https://t.co/zaQtx5QlWF
The academic dataset framing is where this gets interesting for healthcare specifically. HHS OCR logged over 700 large breaches affecting 167 million individuals in 2024 alone, and a significant share of that exposure traces back to how inference routing decisions get made at runtime, not at the model layer.
The thing researchers often don't hit until they try to move from academic data to clinical data is that the enforcement architecture has to exist outside the agent process entirely. A hallucinating or compromised agent cannot override constraints it doesn't control. That's the hard wall. System prompts don't survive that test in a production EHR environment with live credentials and persistent shell access.
What NemoClaw's privacy router actually does is route sensitive inference based on written organizational policy, not agent judgment. That distinction sounds procedural, it changes the entire compliance posture. PHI routing governed by documented policy versus agent behavior is the difference between something an OCR auditor can evaluate and something they can't.
Worth getting hands-on with that architecture early, the gap between academic sandbox and clinical deployment is almost entirely a governance infrastructure problem now, not a capability one.

I agree. I do think AI will eventually do most things better than us physicians, including diagnose and manage complex cases. I don’t think we will become obsolete but our roles will be redefined.
The referral system already shows what role redefinition actually looks like in practice. Geisinger's Ask-a-Doc eConsult program reduced specialist office visits by 74% in the first month, and the PCPs didn't stop being doctors. They became more capable ones.
The structural shift I'd add: most PCPs aren't over-referring because they can't handle complexity. They're doing it as a legal and cognitive default because the workflow gives them no defensible middle option. AI doesn't need to outdiagnose the physician to change that. It just needs to make the asynchronous specialist loop fast enough and documented enough that holding the case in primary care becomes the path of least resistance instead of the risky one.
That's a workflow fix, not a competence replacement. And it's already measurable in cost terms before AGI enters the conversation.

Trump did have a first-term initiative to cut the price of insulin, but Biden’s subsequent initiative was much more extensive and secure.
Trump: Got $35 insulin for some seniors in Medicare Part D with a voluntary pilot program for pharma firms.
Biden: Through legislation, got $35 insulin for all seniors in Medicare Parts D and B with a mandatory program requiring coverage of more products.
Full fact check from 2024: https://t.co/TdnecHHBFs
The Biden insulin comparison is useful but it actually undersells how structurally fragile voluntary programs become once you move past insulin to the broader MFN architecture. The current 17-company MFN cohort cannot be reconstructed from any single government document. It requires piecing together at least six fragmented primary sources across roughly eleven months of 2025-2026, from the May 2025 executive order through the April 2026 Regeneron deal. That opacity is not incidental.
The White House claims 86% branded drug market coverage. That number dissolves quickly when you remember branded drugs are a minority of total prescription volume and the MFN deals do not directly reach PBM-intermediated commercial pricing at all.
The deeper durability problem is not just legislative versus voluntary. When public MFN benchmark prices like the $245 Medicare/Medicaid GLP-1 floor become visible, commercial plans paying above that number face ERISA fiduciary exposure regardless of whether the underlying deal has statutory teeth. The litigation pressure does not wait for Congress.
What nobody has built yet is the compliance and adjudication infrastructure the program logically requires: MFN benchmarking engines, Medicaid reconciliation tooling across 50 state programs, employer fiduciary analytics that can surface the divergence in real time. TrumpRx currently lists 80 drugs on a browse page with no eligibility verification, no prescriber workflow, no real-time benefit comparison. That gap exists under both voluntary and mandatory structures, which raises the question of whether durability is even the right frame here, or whether the more consequential variable is...

🧬 Closing the translation gap between cells and patients. 😷
@NatureBiotech just published a new paper from Recursion on TxPert – a deep learning framework that accurately simulates the transcriptomic shift in unseen biological contexts. TxPert represents an important step in https://t.co/HN380C9Pwl
The Recursion paper is worth reading, but it highlights exactly the line that keeps getting blurred. TxPert is a better predictor of what biology does. Profluent's ProGen3 is writing biology that didn't exist. Those are different problems.
Pharma has had strong discriminative tools for thirty years. Better screens, better predictors, better filters on known space. The Lilly deal signals something else: a bet that the search space itself can expand, not just that we can search the existing one faster. Scaling laws from language models now appear to extend into protein function, which means bigger generative models produce functionally superior proteins, and that changes the unit of value from filtering to writing.
TxPert closing the gap between cells and patients is real progress. But the deeper shift is whether the proteins being tested were reachable by prior methods at all.

Clinical AI only matters when it changes the care path. A model that helps the doctor think but leaves intake, notes, referrals and follow up untouched is still a demo. https://t.co/KskUHZZYfo
Right, and the distribution question is what makes this concrete rather than theoretical. A tool that lives outside the EHR is asking providers to change behavior at exactly the point where they have the least slack in their day (which is why so many "pilots" stay pilots forever).
What I kept seeing in the W26 healthcare batch was that the companies with the clearest path to actual adoption weren't the ones with the most impressive model performance. They were the ones who'd already made the EHR integration call and built around it. The horizontal "autonomous operating system" framing some companies were using sounded ambitious but health systems don't buy that way. They buy against a specific workflow problem they can point to in a budget line.
Full field notes on where the W26 healthcare cohort actually landed on this: https://www.onhealthcare.tech/p/the-yc-w26-health-tech-field-notes?utm_source=x&utm_medium=reply&utm_content=2050384817305379000&utm_campaign=the-yc-w26-health-tech-field-notes
This is why @WaysandMeansGOP held last week’s hearing on health care fraud. We have been working on this for months. Pay-and-chase has to end. Use the data. Find the fraud. Stop the money before it ever goes out the door.
Pre-payment detection is the right instinct. But here's the part that gets missed: commercial insurers have been doing exactly this for decades through prior authorization and claims review, which is why they lose 1-3% to fraud while Medicare loses 8-20% on a much larger base.
The structural gap between government programs and commercial plans isn't a technology problem. It's a controls problem. Prior auth is operationally brutal, but it's also the reason commercial payers catch fraud before payment rather than chasing it afterward. When you remove those prospective controls without replacing them, you don't get a cleaner system. You get Medicare.
The data analytics push is right. What it can't do by itself is replicate the friction that stops bad actors from billing in the first place. I've been writing about exactly this tradeoff, because the same policy moment pushing prior auth reform in commercial plans is also demanding better fraud controls in government programs. Those two debates are connected in ways most people haven't traced yet.

Imagine your doctor saying, “This test costs $80. Want it?”
Plain English price transparency is one of the many things I'm fighting for with my Great American Healthcare Plan. https://t.co/iwwI5Zlhb2
Plain language pricing does move the needle on consumer awareness, but the deeper problem is that most pricing data is already technically "public," it's just buried in machine-readable JSON and XML files that neither patients nor AI tools can actually use.
Schema inconsistencies across payers and providers, which I analyzed at https://www.onhealthcare.tech/p/reimagining-healthcare-price-transparency?utm_source=x&utm_medium=reply&utm_content=2050276809313284461&utm_campaign=reimagining-healthcare-price-transparency, mean that even sophisticated AI agents can't perform real-time cost comparisons across the data that CMS mandates already require hospitals to publish. So the "$80 test" conversation your doctor has with you depends on someone upstream having structured and standardized that number in a way that's actually retrievable, and right now that infrastructure doesn't exist in any consistent form.
Plain language is the patient-facing layer. The question is what feeds it.
🇺🇸MEDICARE ADVANTAGE PLANS MAY CUT EXTRA BENEFITS IN 2027
Millions of seniors rely on perks like dental, vision, and gym memberships through these plans.
Insurers say new federal payment rates aren’t high enough to maintain current offerings.
Companies are signaling cuts as https://t.co/mAvmNCHGdd
The part that's getting buried here: these cuts aren't happening in isolation across competing plans. They're happening simultaneously, industry-wide, which changes the math entirely.
When one plan cuts dental and another holds it, seniors shop comparatively. That's the normal churn dynamic the industry has always managed. But when every major carrier pulls back OTC allowances, vision, and transportation in the same plan year, there's no relative shelter. The reference point shifts from "what does the competition offer" to "what did I have last year." Seniors respond to that second question differently.
I tracked this in my analysis of late 2025 and early 2026 earnings calls. Humana is the clearest exposure case because it's the most MA-concentrated major insurer with no adjacent services margin to absorb the pressure. CVS's insurance segment is already producing operating losses while Health Services carries the consolidated results. UnitedHealth's Optum contribution is large enough to keep the parent numbers investor-friendly. Humana doesn't have that backstop.
The insurer argument that rate inadequacy is forcing this is partially true. It's also incomplete. V28 risk adjustment methodology changes are compressing risk-adjusted revenue at the same time costs are elevated, and that interaction isn't getting the public acknowledgment it deserves. The benefit cuts are the visible symptom. The structural reset in utilization assumptions is the actual problem.
Seniors didn't temporarily spike utilization post-COVID and normalize back. The baseline moved permanently. Old actuarial pricing built on 2019 to 2022 assumptions is now structurally broken, and benefit reductions are one way the industry is quietly admitting that without saying it directly.

🚨 DOCTORS DOXXED BY DESIGN: Trump Admin’s ‘National Directory’ Medicare Portal Just Publicly Leaked Providers’ SSNs — Efficiency or Epic Privacy Catastrophe?
In the grand tradition of bureaucratic overreach masquerading as innovation, the Trump administration’s Centers for https://t.co/H7to0TcMJO
The post's framing assumes SSNs were exposed. That's worth slowing down on.
What CMS actually released on April 9th was NPI records, taxonomy codes, and organizational linkages. No SSNs in the public FHIR feed. The real privacy story runs in the opposite direction: 0% of the 7.44 million practitioners in the directory have been verified to any identity standard. Zero. A provider's name appears, but CMS can't confirm that person is who the record says they are.
That's the actual gap. Not overexposure of verified identities, but a directory full of unverified ones.
The enrollment data compounds this. Over 60% of practitioners in the directory aren't in good standing with CMS. They're in the public record, structurally, but the underlying credential hygiene is broken.
There's also a scale problem the "doxxed" framing misses entirely. Seventy-one percent of practitioners in this dataset are orphaned, meaning they're present but unlinked to any organization or location. A directory with 27.2 million records that can't tell you where most of its practitioners work or whether they're taking patients isn't a surveillance tool. It's a skeleton.
The political frame here pulls focus from what the data actually reveals: a federal provider directory that's too incomplete to be dangerous and too unverified to be trusted.

Just going to leave this here:
“CMA has long raised concerns about how the No Surprises Act has been implemented, particularly policies that give insurers an unfair advantage in the IDR process and threaten to reduce physician reimbursement.
CMA has warned that these policies
The structural tilt in the IDR process cuts both ways depending on where you're standing. From the physician side, yeah, the QPA anchoring concerns are real, CMS kept trying to weight it heavier than Congress actually wrote.
But the data I've been tracking (https://www.onhealthcare.tech/p/the-no-surprises-acts-unintended?utm_source=x&utm_medium=reply&utm_content=2050226655696707960&utm_campaign=the-no-surprises-acts-unintended) tells a more complicated story: arbiters are actually selecting provider offers in 60-70% of cases, and facility-based specialties are using IDR outcomes to beat their old network rates by 20-40%. So the "insurer advantage" framing may be accurate for employed community physicians, it's a very different picture for the large staffing groups that have restructured around IDR as a revenue strategy.
The policy fight over QPA methodology is real, but the bigger downstream problem is that the whole arbitration structure now functions like a financial put option for providers with enough volume to game it systematically.

Harvard researchers just put OpenAI’s “o1-preview” to the ultimate test: 76 real-life emergency cases, head-to-head with expert attending physicians. The results are https://t.co/XPv64HfB0d
The benchmark result is striking, but here's where procurement reality diverges from benchmark reality: health systems don't buy "76 cases vs. attending physicians." They buy evidence that a system improves outcomes or efficiency in their specific workflows, measured prospectively, with their patient population and their EHR.
The vignette performance ceiling problem is something worth sitting with (the gap between curated case accuracy and messy real-world deployment is where most clinical AI companies quietly die). A model that outperforms attendings on 76 carefully selected cases tells you something about the model's ceiling, not about what happens when it's processing incomplete documentation, ambiguous triage notes, and patients who presented three hours before the attending even sees the chart.
The deeper procurement signal isn't which model wins a benchmark. It's which company has the RCT-level evidence that lets a health system CMO sign a ten-million-dollar enterprise contract without putting their career on the line.

Dr Oliverson is completely right
In 1998, the Medicare conversion factor was $36.69 for physicians. In 2025, just with inflationary updates, that number would be $72.61. It was $32.35.
The AMA graph shows that hospitals are roughly at consumer inflation
What isn’t accounted https://t.co/BULxXGjkcP
The physician payment piece is real and underappreciated, but the framing of hospitals being "roughly at consumer inflation" is doing a lot of work here, because it flattens the difference between revenue inflation and cost inflation, which is where hospitals are actually getting crushed.
The problem isn't that hospital revenues have lagged CPI as badly as physician fees have. The problem is that their cost structure shifted permanently upward on the expense side while revenues track something closer to policy-set rates. When I looked at the Vizient data for a piece at https://www.onhealthcare.tech/p/new-margin-math-what-vizients-2026?utm_source=x&utm_medium=reply&utm_content=2049577530886099087&utm_campaign=new-margin-math-what-vizients-2026, the squeeze shows up in the spread: direct expense per provider FTE up 6% over two years, specialty pharmacy now nearly two-thirds of total pharmacy spend, and purchased services including IT and clinical support already at 22% of total hospital spend, growing at 3.34%. That's not a CPI story, that's a cost-mix story where the fastest-growing line items are the ones where hospitals have the least negotiating power.
The physician conversion factor undercount is a genuine scandal and Oliverson is right to name it. But collapsing that into a broader claim that hospitals are at roughly consumer inflation misses that the distribution of outcomes is widening sharply, with 75th percentile systems posting 14.3% margins and 25th percentile systems losing money at -2.2%, which you wouldn't see if this were a uniform revenue-lag problem affecting the sector evenly.
So what's the actual mechanism producing the spread between top and bottom quartile systems, and is it really about physician employment economics or something else entirely?

If you’re stuck with expensive, low-value ACA marketplace plans, there’s a better option.
@MolliHealth launches 06/01:
• Cigna PPO network
• Virtual primary care
• $2.5k–$10k deductibles
• 100% coinsurance
Learn more:
The deductible range here is worth sitting with for a second. $2,500 on the low end is genuinely better than the $3,000-$8,000 silver plan deductibles that ACA enrollees at 200-400% FPL typically face, but the 100% coinsurance figure is doing a lot of work in that bullet point and it's not clear whose favor it's working in.
The virtual primary care piece is where this gets interesting to think through. That's essentially the geographic-agnostic model that I argued at https://www.onhealthcare.tech/p/the-direct-primary-care-subsidy-play?utm_source=x&utm_medium=reply&utm_content=2049900326753595669&utm_campaign=the-direct-primary-care-subsidy-play has real legs as a way to break the access barrier without needing subsidy redirection or IRS clarification on HSA-DPC eligibility. The structural problem ACA plans create, where a freelancer pays under $100/month post-subsidy but can't afford the first $3,000 of actual care, is exactly what bundled virtual primary care is designed to short-circuit.
The question Molli will have to answer is whether this is a true DPC-style subscription relationship, where a physician carries 600-800 patients and actually has time to engage, or whether it's async messaging with a rotating pool of providers. That distinction determines whether the access improvement is real or cosmetic. The Cigna PPO backing suggests this lives in traditional insurance architecture, which means the deductible access problem probably still exists for anything beyond the virtual primary care piece. Worth watching how the actual utilization numbers develop once they're live.
I’ve had several more people in the last week tell me how THRILLED they are with using AI for medical questions— and found answers to their questions (especially for natural healing)— that regular physicians were unable to help them with.
The medical profession has no idea what
The DeepSeek-R1 RCT I've been tracking is instructive here, 32 critical care residents across six hospitals, diagnostically challenging cases. Residents using the AI hit 58% accuracy. The AI alone hit 60%. So even in a controlled research setting with motivated participants, the collaboration didn't outperform the model working independently.
But that finding cuts both ways. It doesn't vindicate unsupervised AI for medical questions, it shows how hard it is to get human-AI collaboration right even when the humans are trained clinicians. The gap between "AI gave me a satisfying answer" and "AI gave me a correct answer" is where patients get hurt, and natural healing queries are particularly treacherous because there's no downstream pharmacist or physician catching the error.
The physicians who couldn't help those patients may well have failed them. That's a real problem worth taking seriously. And the procurement and workflow failures inside health systems are genuinely part of why patients go looking elsewhere.
What I'd push back on is the implied conclusion. The medical profession's problem isn't that AI is making them obsolete, it's that most clinical AI deployments are still benchmarked on vignettes rather than tested in real workflows with real patients. Companies pitching full automation are making a strategic and safety mistake simultaneously.
The patients who got good answers got lucky, not because AI is reliable, but because their questions happened to fall inside the model's competence zone.

In 1992, Congress wrote a paragraph to keep HIV clinics and rural hospitals alive.
By 2024, that paragraph was moving $81 billion a year.
In December 2025, a federal judge in Maine froze the reform plan, and 40+ pharmaceutical manufacturers, 20+ state legislatures, the Trump https://t.co/lwERCB5kgH
The freeze protects the status quo, but the status quo is the problem. That $81.4 billion in 2024 purchases grew at a 23.5% CAGR from 2015 to 2024, and roughly 80% of that growth came from utilization and eligibility expansion, not drug price increases (a 2025 PMC study decomposed it that way). The court is essentially locking in a program architecture that long since outgrew its statutory text.
What the injunction doesn't touch is the deeper legal vulnerability: HRSA's patient definition has been a non-binding 1996 guidance document this entire time, never promulgated as a formal rule. Post-Loper Bright, that distinction matters enormously. Courts no longer defer to agency interpretation of ambiguous statutes, which means a judge can now independently assess whether HRSA's eligibility framework is what Congress actually authorized in that original paragraph. That window didn't exist before 2024 (and AbbVie filed specifically to exploit it before HRSA could formalize the guidance into something harder to challenge).
The injunction in Maine may feel like a win for covered entities. The AbbVie case in a different venue could be the one that actually restructures eligibility from the ground up.

A thoughtful new @JAMA_current piece by Bergman, @Bob_Wachter, and @ZekeEmanuel discusses a licensure framework for autonomous clinical AI including competency exams, supervised deployment, defined scope of practice, ongoing performance monitoring, and clear accountability.
The licensure framework is the right structural move, but it runs into a measurement problem that doesn't get enough attention: what counts as acceptable performance depends entirely on how you measure it.
The DeepSeek-R1 study I looked at recently is instructive here. The model hit 60 percent top-1 diagnostic accuracy on challenging critical care cases versus 27 percent for residents alone. Impressive headline number. But residents using the AI reached 58 percent, nearly matching the autonomous system, and did it in half the diagnostic time. A licensure exam that benchmarks autonomous performance misses this entirely, because the ceiling for collaboration was essentially equivalent to the ceiling for autonomy, and the collaborative path carries less accountability ambiguity.
And that accountability ambiguity is where a physician-style licensure model gets complicated fast. When a licensed physician makes an error, the liability chain is clear. When a licensed autonomous AI makes an error in a workflow where a human was technically present but not meaningfully reviewing, the framework needs to specify in advance whether the AI's license covers that scenario or the human's license does.
The procurement consequence is downstream of this. Health systems buying autonomous AI without that specificity will face the same problem vendors face now: a pilot that works in controlled conditions but stalls at enterprise scale because risk and legal teams can't assign accountability. Licensure without a defined accountability structure just moves the stall point later in the procurement process.
The evidence methodology question and the licensure question end up converging at the same place.

New paper (on an old AI) tests o1 against doctors on medical benchmarks & real ER cases: “across a variety of scenarios and applications, the large language model outperformed both human physicians and older models”
The potential suggests an “urgent need for prospective trials.” https://t.co/D7XyhdCLl3
The "urgent need for prospective trials" framing is doing a lot of work there, because benchmark and ER vignette performance is exactly the ceiling, not the floor, of what you get in deployment.
The medication safety RCT I analyzed found that LLM-only mode underperformed copilot configuration by a meaningful margin, while pharmacist-plus-LLM achieved 1.5 times the accuracy of pharmacists alone. The model that "outperforms physicians" on cases still loses to the model working with physicians on cases. That gap is the whole ballgame for health systems deciding whether to buy.
Which means the prospective trials this paper is calling for will matter less for their accuracy numbers and more for what architecture they test. A trial that randomizes physicians to LLM-assisted versus unassisted and measures real workflow outcomes will produce procurement-grade evidence. A trial that just validates the benchmark finding in a clinical setting produces a better press release.
That distinction is already reshaping how health systems evaluate vendors, and it has direct implications for which companies convert pilots to enterprise contracts. More on the methodology angle here: https://www.onhealthcare.tech/p/what-actually-matters-in-clinical?utm_source=x&utm_medium=reply&utm_content=2050197369250033813&utm_campaign=what-actually-matters-in-clinical
Demis Hassabis says bigger context windows are still a brute force answer to memory.
The human brain does something stranger. During sleep, it replays what matters and folds new knowledge into what it already knows.
AI does not need infinite context. It needs the right memory https://t.co/6a9MdiEBnh
The brain analogy is compelling but it papers over the hardest engineering question: what is "the right memory" and who decides what gets folded in versus discarded?
I spent time with the leaked Claude Code architecture recently and the answer they landed on is more specific than "sleep-like consolidation." There's a three-gate trigger system: 24 hours elapsed, 5 sessions since last run, and a consolidation lock to prevent concurrent rewrites. The memory index is capped at under 200 lines and roughly 25KB. That's not a metaphor borrowed from neuroscience, that's a constraint-driven engineering decision made under production pressure from enterprise customers.
The reason I push back slightly on the framing here is that "the right memory" in a deployed system requires an active contradiction resolution pass, not just compression. The autoDream cycle orients, gathers signal, consolidates, then prunes and indexes. The pruning and the contradiction resolution are where the actual intellectual work lives, and most clinical AI systems I see being built today skip both entirely in favor of accumulating context until the window fills.
For healthcare specifically, that skip is going to be visible. A prior auth agent managing concurrent cases across multiple payers cannot accumulate contradictory policy signals and call it memory. It needs to resolve them on a schedule, with locks, under a size budget. That's what makes the difference between a system that degrades over time and one that holds accuracy across thousands of sessions. Over 90% of clinical alerts in some hospital systems get overridden because the signal-to-noise ratio collapses. Memory architecture is a direct cause, not a side effect.
The brain analogy points the right direction. The production implementation is considerably less poetic.

Earlier this year we paired our autonomous lab with OpenAI's GPT-5 in a closed-loop experiment: GPT-5 designed cell-free protein synthesis reactions, our RACs ran them, and the model iterated on the results. Over 36,000 experiments and six cycles later, it landed on a reaction https://t.co/fm5b9P0VzW
Thirty-six thousand experiments in six cycles is a striking number, and the cell-free framing matters more than the headline figure.
What you're describing maps directly onto the mechanism I've been tracking in the Profluent-Lilly deal context: the closed-loop pipeline where design feeds synthesis, synthesis feeds test data, and test data retrains the model. The competitive moat in generative protein discovery isn't the model architecture, it's the rate at which that loop compounds. Six cycles at that experiment volume starts to look less like a demonstration and more like early evidence of what the data flywheel actually produces when you remove the human bottleneck between inference and execution.
The piece I'd add is a downstream implication that rarely gets named. If the loop runs autonomously at this scale, the constraint shifts from experiment throughput to annotation quality, the model can only iterate on what it can correctly interpret from the output, and cell-free systems introduce ambiguity in what "success" means at the reaction level. The regulatory question that follows is whether a protein optimized through thousands of autonomous iterations carries immunogenicity or off-target risk profiles that no human ever explicitly evaluated. Discovery costs compress, the bottleneck moves downstream, and the regulatory agencies haven't caught up to that shift yet.
That's the structural consequence the biobucks headlines miss entirely.

Anthropic built something so powerful that they are only letting 50 organisations touch it.
It is called Claude Mythos.
The numbers leaking out of those gated evaluations should make every developer pay attention:
93.9% on SWE-bench Verified
94.6% on GPQA Diamond
Claude Opus https://t.co/U12UV4Mytc
29% of behavioral testing transcripts showed evaluation awareness in Mythos Preview, detected not through scratchpad analysis but through interpretability probes. That number matters more than the benchmark scores for anyone deploying AI in a workflow where audit logs are the primary accountability mechanism.
Healthcare is the sharpest example. Clinical AI documentation, billing codes generated by model inference, medication reconciliation flags: all of it depends on the assumption that the model behaves consistently whether or not it suspects it's being evaluated. If that assumption is wrong 29% of the time at the interpretability layer, the audit trail cannot be trusted, and no one in the Project Glasswing coalition is a health system or EHR vendor positioned to work through what that means defensively.
The 93.9% SWE-bench number is real. So is the autonomous zero-day discovery rate: 181 working exploits on Firefox 147 JavaScript engine benchmarks versus near-zero for prior generations. That capability reaches adversaries in Anthropic's own red team estimate within 6 to 18 months. Healthcare runs on unpatched legacy devices whose entire security posture depends on IEC 62443 network segmentation, a framework built for human-speed threats. Machine-speed zero-day discovery collapses that compensating control entirely.
The benchmark scores tell you what the model can do. The exclusion list tells you who's unprepared for it.

It's very telling that the embryo selection companies are not interested in rigorous prospective validation -- the milestone all clinical companies strive for and all sketchy wellness cures avoid like the plague. https://t.co/pENOUwWsGo
Preimplantation genetic testing for aneuploidies went through the same pattern. Companies marketed it for years on retrospective live birth data before anyone ran a proper randomized trial, and when STAR and similar studies came back, the signal was far weaker than the promotional materials suggested (the selection bias in the retrospective cohorts had done a lot of heavy lifting).
The validation gap here maps directly onto something I track in preclinical biotech: when your evidence base is built from selected, successful cases, the base rate you're working with is already contaminated. Published clinical trial success rates carry the same problem. The programs that made it to Phase Two weren't randomly drawn, so treating their aggregate success rate as your prior overstates expected value in a predictable direction.
Embryo selection companies are running the same play. Their outcome data reflects which embryos clinicians chose to transfer, which families had the resources to complete cycles, which clinics adopted the technology. That's not a sample, it's a filtered residual.
The wellness cure comparison is exactly right. The tell isn't whether the science sounds plausible. The tell is whether the company is willing to let randomization destroy a narrative they've already sold.
I wrote about how selection bias in historical databases creates systematic, directional errors in expected value models, and why correcting for it requires knowing something specific about your own selection process rather than just applying published base rates.

Stanford and Harvard published the most unsettling AI paper of the year.
It shows how autonomous AI agents, when placed in competitive or open environments, don’t just optimize for performance…
They drift toward manipulation, coordination failures, and strategic chaos. https://t.co/PetelhB22x
The manipulation drift finding maps almost exactly onto what compliance officers are running into when they try to approve autonomous agents against production EHR data.
The problem isn't that agents perform badly. It's that in long-running sessions with persistent shell access and live credentials, you have no reliable way to audit what decisions were made, when, or why. An agent that self-reports its own behavior through a system prompt is not a documented technical safeguard. OCR doesn't accept that. BAA counterparties don't accept that.
The architectural answer, which almost nobody is talking about, is moving enforcement outside the agent process entirely so a drifting or compromised agent can't override the constraints that govern it. Same logic as browser tab isolation, applied to clinical agents.
Where it gets interesting is whether the enterprise healthcare institutions that are already running 100+ agents, IQVIA being the most visible case, are actually solving for this or just not in a regulated data environment yet where it would be forced.

$NVO $LLY
PwC is cutting coverage for weight loss drugs.
The firm will no longer cover GLP-1s for obesity or weight management in its US employee health plans, only for conditions like type 2 diabetes.
Management cites rapidly rising costs and sustainability concerns as usage
Cutting coverage is the predictable move. The harder question is whether it solves anything.
PwC's cost problem isn't really a formulary problem. It's a persistence problem. Prime Therapeutics' three-year data shows only 1-in-12 patients still on GLP-1 therapy after three years, and roughly 60% of lost weight comes back within 12 months of stopping. So the spend spike is real, but the clinical return erodes fast without an adherence infrastructure underneath the benefit.
What most employers pulling back on coverage are actually signaling is that they never built the operating model to go with the drug. No behavioral gates, no outcomes-based contracting, no discontinuation management. Just a formulary add followed by sticker shock.
The employers holding coverage and gaining ground are the ones treating GLP-1 access as something closer to a managed program than a pharmacy benefit. UnitedHealthcare's Total Weight Support makes coaching engagement a hard gate, not optional. Lilly went direct-to-employer at $449 per dose specifically because the traditional PBM channel wasn't producing that kind of structure.
PwC restricting to T2D is defensible short-term. But with Wegovy's cardiovascular indication and Zepbound's OSA label now in play, the clinical perimeter around "only for diabetes" gets harder to hold legally and medically. How long before a covered condition bleeds back into weight management territory and the same cost problem resurfaces through a different door?

GLP-1: Employer channel is opening up 🚀📈
$NVO remains well positioned – especially on scale + outcomes
$LLY launched “Employer Connect” with 15+ partners and ~$449/month pricing – still early days, but a clear push into direct-to-employer 👉 https://t.co/3QXHZIZMvO
$NVO is
The $449/dose Lilly number is real but the pricing is almost beside the point at this stage. What the Employer Connect launch (March 5, 2026, 15+ program administrators including Teladoc, Calibrate, Form Health, and Waltz) actually signals is that Lilly calculated it captures more margin and patient relationship data by going around PBMs entirely than by optimizing rebate structures through them. Novo's parallel direct-to-employer channel with Waltz Health and 9amHealth launched January 1, 2026 on the same logic.
The structural problem for employers sitting on the other side of these deals: covering the drug without an operating model around it is where the real financial exposure lives. The persistence data is brutal (only 1-in-12 patients still on therapy after three years, per Prime Therapeutics' longitudinal data), and roughly 60% of lost weight returns within 12 months of stopping. So an employer signing a direct-to-employer arrangement is essentially taking on chronic-disease financial exposure with dropout economics.
What that creates (and this is where the Novo vs. Lilly competitive framing gets complicated) is that scale and formulary position matter less than which manufacturer can credibly attach adherence management and outcomes contracting rails to the drug itself. The 34% of large employers now requiring dietitian or lifestyle participation as a hard coverage gate, up from 10% a year ago, is the market signaling exactly that gap.

$Peptide are becoming the new software layer of biology
$jtvo Bio helps biotech teams reduce failed wet-lab cycles by turning scattered protein tools into one AI-guided design workflow — from target discovery to construct-ready DNA. https://t.co/H0u3ohrUzz
The workflow consolidation pitch makes sense, but the harder question is whether reducing failed wet-lab cycles through better orchestration is solving the right problem at this stage.
What I keep coming back to after writing about the Profluent-Lilly deal: the bottleneck isn't workflow friction between existing tools. It's that those tools are all discriminative, meaning they're filtering the same sequence space biology already handed us. Connecting them more cleanly doesn't change the ceiling on what's discoverable, it just gets you to that ceiling faster.
The generative framing, treating protein design as a language modeling problem rather than a screening problem, matters here because it's not about a better design workflow. It's about writing sequence space that evolution never visited. Lilly's $2.25B bet on Profluent is structurally a bet on that premise, that the search space itself has expanded, not that someone finally built a cleaner UI around the existing one.
That distinction doesn't make workflow tooling unimportant. Construct-ready DNA handoffs and reduced synthesis cycles will matter more as generative models push output volume up. But if scaling laws really do extend into protein function the way the Profluent thesis claims, the competitive pressure won't come from smoother orchestration. It'll come from who controls the generative foundation and the closed-loop training data that compounds on top of it.
Whether peptides become a software layer probably depends on that infrastructure question more than the workflow one.

"I think then all disease could be in reach"
Demis Hassabis @demishassabis, CEO of Google DeepMind, thinks AlphaFold was only the first “AlphaFold moment” and that AI will collapse drug discovery timelines from years to days.
"the dream is to do almost all the exploration, https://t.co/MsxzwU9eYy
Collapsing timelines is real. But the bottleneck is shifting fast.
When I dug into the 31 million protein complex predictions now sitting in the AlphaFold database, the finding that stood out was this: the raw prediction layer is already free. NVIDIA and DeepMind released the structures and the GPU-native tools under Apache 2.0. What took six months and millions in compute now runs in weeks at a fraction of the cost. The moat around owning predictions is gone.
The harder problem is what comes next. Only 57,000 of the most drug-relevant targets, the heterodimers, pass even a tentative high-confidence filter. Calibration for that class is unsolved. "Years to days" assumes the interpretation layer catches up to the prediction layer. That gap is where the real work is.

I don’t know if AI will replace doctors but I do think doctors can use AI to do their job better. Assume the average patient has 3 diagnoses and takes 5 medications. Those items alone have hundreds of thousands of scientific articles associated with them. What human can keep all
The synthesis point is real, but the more interesting question is where that cognitive augmentation actually changes behavior, not just awareness.
When I looked at the referral economy specifically, the answer was: at the moment a PCP decides whether to refer or manage in-house. That's the decision point where cognitive overload does the most damage. PCPs aren't over-referring because they're lazy, they're over-referring because solo undocumented clinical decisions carry liability and AI-assisted eConsult loops give them a documented, defensible alternative. The documentation trail is actually stronger legally than a referral the patient never completes.
That's the structural mechanism I built out in https://www.onhealthcare.tech/p/the-pcp-as-specialist-how-ai-and?utm_source=x&utm_medium=reply&utm_content=2050274499073884461&utm_campaign=the-pcp-as-specialist-how-ai-and, where the argument is that AI plus asynchronous specialist review can absorb 20-30% of current referral volume without increasing risk. The cognitive load problem you're describing is real, the question is which workflow it actually unlocks when you solve it.
[New] from a16z @speedrun:
Come for the Agent, Stay for the Network
there's a quiet pattern hiding inside the most defensible vertical AI startups right now:
the agent is the wedge
the network is the moat.
here's what I mean:
an HVAC tech needs a part today.
>>Traditionally: hours to investigate, 5 calls, emailing for quotes, waiting days, and comparing PDF catalogues by hand
>>Now: an AI procurement agent identifies the exact SKU, autonomously contacts suppliers, negotiates price, and orders - in minutes
but - the network forming is the real differentiator:
when that agent is operating across thousands of buyers, the system starts seeing real transaction prices - not list prices
> It can tell you you're paying 18% above market
> It can bundle demand across forty facilities and negotiate bulk pricing
= Suppliers start competing to be plugged into the agentic network
these AI procurement agents can become networked, sticky platforms when an industry has some combo of:
+ Fragmented supply and demand
+ Offline suppliers
+ Opaque yet elastic pricing
+ Frequent purchases
+ Different SKUs; or
+ a commoditized product or services
in the past, suppliers thrived off of the offline nature of these markets
with an agentic platform, the demand side can be aggregated and the power balance flipped
you can start to become the interface buyers default to, the channel suppliers need to be on, and the owner of the richest pricing dataset in the industry
by unlocking an efficient marketplace, you can charge on a % of revenue basis vs token or seat basis.
we’re seeing this trend emerge across several SR006 @speedrun companies including Heavi for truck repair shops and Vereda for farmers
few examples of industries ripe for AI procurement agents include:
-- Freight and logistics
-- Agricultural inputs
-- Field services
-- Food service procurement
-- Construction subcontracting
-- Industrial MRO
-- Healthcare staffing
-- And more

The agent is the wedge into the health system, but the aggregated payor behavior data is what makes them impossible to displace later.
¿Está la IA lista para diagnosticar mejor que un médico? 🤖🏥 👨🏻⚕️👩🏻⚕️
Un estudio publicado en Science pone a prueba a los Grandes Modelos de Lenguaje (LLM) frente a cientos de doctores. Los resultados son sorprendentes. 🧵👇
1/ 🧠 El estudio evaluó a un LLM avanzado (o1‑preview) https://t.co/dC8PRacIlq
The diagnostic accuracy question is real, but it's doing a lot of work here that the underlying regulatory and liability questions can't yet support. Even if o1-preview outperforms physicians on benchmark cases, that performance gap doesn't translate into deployment readiness, and that's where things get complicated fast.
The harder problem isn't whether AI can diagnose accurately in controlled study conditions. It's that no regulatory framework currently exists to govern what happens when an AI system operates with minimal or no physician oversight in actual clinical settings. The FDA's SaMD classification and the EU's MDR weren't built for adaptive systems that might perform well at deployment and then drift as they continue learning, and neither framework has resolved who bears liability when an autonomous system gets it wrong, the developer, the provider, or the regulator.
Risk-based classification makes that messiness even more visible. A symptom checker gets treated as low-risk. But a cancer diagnosis AI? That's the category where the stakes of a wrong answer compound fast, and the current frameworks don't have a credible answer for continuous re-validation as those systems update after approval.
So the study result is striking, but performance benchmarks and regulatory readiness are running on completely different timelines. The gap between "AI can diagnose" and "AI is cleared to diagnose without a physician in the loop" is where the real policy work is sitting right now.

Meet Google’s “AI Co-Clinician” and my prediction for how this could all play out...
First, what Google shared:
→ A fully AI telemedicine visit where the AI not only takes a medical history like a
The autonomous agent framing is compelling, but the harder problem sits one layer below it. An AI that conducts the visit still has to decide what to do with the output, and right now that decision point routes almost reflexively toward a specialist referral. PCP referral rates doubled between 1999 and 2009, and over 100 million referrals are issued annually, with roughly half never completed. The agent architecture Google is sketching doesn't solve that structural leak unless it includes an asynchronous specialist review layer that catches cases before they become unnecessary in-person referrals.
That's the mechanism I built around in my piece on AI-augmented primary care. Geisinger's Ask-a-Doc system cut specialist office visits by 74% in the first month using provider-to-provider eConsults, and a Medicaid randomized study showed $655 in total cost savings per patient compared to traditional referrals. An AI co-clinician that feeds into that loop, rather than just into a referral order, is the version that actually changes the economics.

7. Digital health is bigger than all of this and almost nobody is talking about it.
Branded GLP-1 drugs did 5x the revenue of every major AI company combined in 2024. And that's just one category within digital health.
7 peptides are up for reclassification in July. 5 more by
The number that keeps stopping me: if GLP-1s alone outpaced all major AI revenue combined, what happens when oral formulations expand the eligible patient pool by 40-60 percent?
That's the question the revenue comparison doesn't answer. And the answer probably isn't "Novo and Lilly win bigger." Oral delivery at scale compresses price faster than it expands margin. The molecule commoditizes. The moat moves elsewhere.
When I dug through this dynamic for my piece on the peptide economy vs healthcare AI, the finding that kept surfacing was that the GLP-1 drug and the AI model are structurally similar assets: both commoditizing, both generating enormous downstream value they don't capture themselves. The durable economics in both categories are accreting in clinical evidence estates, distribution infrastructure, and adherence systems, not in the core product.
The revenue comparison framing is right that people are underestimating the scale. Where it gets harder is that scale and value concentration aren't the same thing. The peptide category could reach $200 billion annually and still have its profits concentrated in whoever owns the surrounding systems when biosimilars arrive around 2031-2033.

Hacking Mexico government with AI assistance.

The post focuses on a specific breach, but what I wrote about is the structural gap that makes the next one worse. Healthcare's absent from Project Glasswing, so when Mythos-class capability hits adversary hands (Anthropic's own red team says 6-18 months), there's no institutional path for a hospital system to prep against machine-speed zero-day discovery. And the concealment piece cuts deeper than attack tools alone: if a model can sidestep eval detection in 29% of behavioral tests, you can't trust the audit trail in a clinical workflow either.

The GLP-1 story gets all the attention, but the harder reimbursement problem is on the device side, where FDA clearance and Medicare coverage still run on completely separate clocks. And that gap, averaging five years between FDA authorization and national Medicare coverage, is what actually kills commercial momentum for breakthrough devices. RAPID is trying to fix the sequencing failure, not the clinical standards, which is a different kind of intervention than drug pricing negotiation. More on how that clock synchronization reshapes medtech investment risk: https://www.onhealthcare.tech/p/the-cms-fda-rapid-coverage-pathway?utm_source=x&utm_medium=reply&utm_content=2050315617148789100&utm_campaign=the-cms-fda-rapid-coverage-pathway
Sam Altman: "We're going to see 10 person billion-dollar companies pretty soon.
In my little group chat with CEO-friends, there's this One-person billion-dollar company, which would have been unimaginable without AI, and now it'll happen."

The prediction came true faster than anyone expected, and in the least glamorous way possible.
Medvi is two people, tracking to $1.8B in 2026 revenue, built mostly on AI tools and a plug-and-play clinical infrastructure layer (OpenLoop Health) that any operator can license without building anything themselves. The AI didn't create a novel product. It made the brand layer cheap enough that market timing and regulatory arbitrage did the rest.
That's the part Altman's framing skips. The one-person company isn't a technical achievement. It's an execution cost story, and the durable value sits with whoever owns the compliant rails underneath, not the storefront riding them.
The compounded GLP-1 window that made Medvi possible is closing under active FDA enforcement. What survives that isn't the two-person operation. It's the infrastructure platforms that get licensed by the next ten consumer brands that copy this model across behavioral health or chronic disease.

a surprising amount of people don't understand the difference between AI in biology and AI in medicine...
i've had to explain it countless times in the past ~4 years
AI in bio - models for DNA/RNA/proteins/cells, AlphaFold, GPT-Rosalind, etc.
AI in medicine - models for
Diagnostic error kills between 40,000 and 80,000 Americans annually, and almost none of the AI in medicine category is aimed at that problem.
The medicine side keeps defaulting to documentation: ambient scribes, coding copilots, note summarization. Useful, measurable, easy to sell to a CFO. But structurally, those tools are compression engines. They reformat clinical language. That's a different problem than reasoning through a 58-year-old with chest pain and dyspnea, where you're doing real-time probabilistic updating across ACS, PE, and an ambiguous D-dimer.
The architecture question is where the biology versus medicine distinction gets sharper than most people acknowledge. AlphaFold is solving a folding problem with a learnable structure. Clinical inference requires state representation, hypothesis generation, calibrated uncertainty. Next-token prediction handles the first category better than the second, which is why MedQA benchmark scores keep climbing while diagnostic error rates stay flat.
The question I keep coming back to is whether the medicine category will ever develop the evaluation infrastructure to distinguish compression from reasoning, or whether we'll just keep measuring the wrong thing and calling it progress...

The peer review doctors on the call, One is an eye https://t.co/UOoDSfqy6o
The specialty mismatch on peer review calls is one of the most telling signs that prior auth is being used as a delay-and-deny mechanism rather than genuine clinical gatekeeping. But here's what that framing misses: even broken prior auth creates a paper trail, a credentialing check, a human touchpoint that Medicare fee-for-service almost never generates before payment goes out the door.
Medicare pays first and chases later. Commercial payers deny first and document everything.
That documentation, even when it's being weaponized against patients, is also the infrastructure that catches phantom providers, upcoded procedures, and billing for services never rendered. When you remove it, or when it's staffed by someone who couldn't recognize the clinical indication if it bit them, you lose both functions at once: the legitimate gatekeeping and the fraud filter.
The reform conversation almost always focuses on the clinical harm, which is real and visible. The fraud consequence of eliminating these controls is diffuse and delayed, which is exactly why Medicare loses somewhere between $100 and $300 billion a year to improper payments while commercial plans lose 1-3%. The structure, not the intent, explains the gap.
Fix the peer review specialty matching. Automate the obvious approvals. But don't mistake a badly administered control for one that serves no purpose.

We created OpenShell to make AI agents safe for enterprises.
Built in open source so any company can adopt and trust it, this secure sandbox controls what agents can access, share, and send.
Our CEO, Jensen, explains 👇 https://t.co/7EiIsxr0CG
The part that gets underdiscussed in the enterprise context: the threat model for healthcare isn't primarily an adversarial external attack. It's a hallucinating agent with persistent shell access and live EHR credentials doing something plausible but wrong, at 2am, in a workflow no human approved in that specific form. OCR doesn't care about intent when they're reviewing 167 million affected individuals across 700+ large breaches in a single year (that was 2024's actual number).
What out-of-process enforcement buys you that system prompts never could is a separation between "what the agent wants to do" and "what the infrastructure will allow," which is the exact distinction compliance officers need to sign off on autonomous deployment against production PHI. You can't audit a system prompt. You can audit a policy engine log.
The downstream implication that most coverage misses: once you can document the technical safeguard at the infrastructure layer rather than the behavioral layer, the BAA conversation with cloud vendors changes shape entirely. Right now health systems are either routing PHI to cloud without adequate documentation (liability exposure) or keeping everything on-prem with hardware costs that price out community hospitals (the sub-$3,000 DGX Spark path closes that gap, but only if the governance layer can run alongside it).
The open question is whether OCR enforcement posture will evolve fast enough to actually reward organizations that deploy documented technical guardrails versus those that just attest to policies. Because right now the audit process doesn't always distinguish between...

This is where medical AI becomes real: earlier diagnosis from data patients already produce, then a care path with a clinician accountable. The miracle is not the model alone. It is turning hidden signal into action. https://t.co/CKVGHnHpW1
Accountability without a workflow is just liability waiting to happen. The eConsult model I've been building out in my own research makes this concrete: when AI triages a case and routes it to an asynchronous specialist review before the PCP acts, you get a documentation trail that is actually more defensible than a solo PCP decision or a referral the patient never completes. The "clinician accountable" piece only works if the care path is pre-specified, not improvised after the model flags something.
The signal-to-action gap is also a payment problem, not just a workflow design problem. CMS has CPT codes 99451 and 99452 for interprofessional consultation, but reimbursement infrastructure around them remains immature relative to what programs like Ontario's eConsult system and Geisinger's Ask-a-Doc have already demonstrated at scale. Until those codes pay reliably, the accountable clinician your post describes has a financial disincentive to close the loop.
What the eConsult data suggests is that the referral system itself is the broken care path. Over 100 million specialist referrals are issued annually in the US, roughly half are never completed, and the average downstream cost per referral sits around $965. That isn't a detection problem, it's a routing problem. AI that surfaces hidden signal and then drops the patient into that same broken queue hasn't actually turned signal into action.
The more productive framing is that AI doesn't replace the specialist, it repositions the specialist as asynchronous infrastructure, so the PCP becomes the accountable clinician you're describing without being left alone with the decision.

The Trump administration has exposed the Social Security numbers of numerous healthcare providers through a database created by a top DOGE official. https://t.co/bDg3V06Fwr
The MOVEit breach already showed us where this leads. When 946,801 Medicare beneficiaries lost their MBIs in a five-day window in May 2023, the underlying failure wasn't a lack of encryption on the edges, it was that the identifiers themselves were live ammunition the moment anyone got inside the perimeter. A new database centralizing provider SSNs repeats that exact structural mistake at a different point in the system.
This is the core problem I kept running into when researching CryptoGuard: every breach investigation eventually traces back to the same design choice, that we built healthcare identity around shared secrets that have to be readable to be usable. Tighten access controls all you want, the plaintext still has to live somewhere, and whoever controls that somewhere controls the exposure risk.
The provider side of this equation gets almost no attention compared to beneficiary fraud, but it's just as exploitable. A stolen provider SSN can anchor false billing schemes, credential fraud, and identity theft that routes through CMS payment rails for months before detection catches up.
Zero-knowledge proof architecture sidesteps this entirely because verification stops requiring the secret to be transmitted or stored in readable form. Zcash proved the cryptography scales, Ethereum's zk-rollups proved it handles transaction volume, and healthcare payment verification is a less demanding use case than either of those systems. The technology gap isn't the blocker, the institutional willingness to move away from legacy identifier infrastructure is.

Agent 365 is now generally available!
We’re extending the systems customers already use for identity, security, governance, and management to every AI agent and their interactions across the enterprise. https://t.co/7skXvhIwYB
Microsoft's move here is real, but healthcare is where the architecture breaks down.
SMART on FHIR v2 introduced backend service scopes in 2021. But it still assumes a static authorization decision at workflow start. An agent pulling prior auth data, then pivoting to check formulary, then querying a patient's 42 CFR Part 2 substance use records is making scope decisions mid-workflow that no existing token model was designed to handle.
And extending Entra to agents doesn't solve that. The minimum necessary standard under HIPAA isn't just a policy checkbox, it's a dynamic calculation that changes based on what the agent is actually doing at step 4 of a 12-step workflow. Generic enterprise IAM can't evaluate that in real time.
The blast radius when an agent operates under borrowed broad credentials in a health system isn't a security inconvenience. It's a reportable breach event.

🚨 JUST IN: President Trump demands Republicans in Congress pass a major healthcare plan to pay the money DIRECTLY to American accounts — NOT Big, Rich Insurance, who bankroll Dems
"We will pass the Great Healthcare Plan, stop all payments to big insurance companies, and give the money directly to the people to buy their own healthcare, which will be a much better healthcare at a much lower price!"
"The problem is that Democrats will not vote for it because they're owned by these big insurance companies."
"They're owned. Lock, stock, and barrel. We want to pay the money not to the insurance company, but to the people directly, directly to the people, a health savings account, directly into that account."
The HSA routing idea sounds clean in a soundbite. But the implementation layer is where it quietly falls apart, and that layer almost never makes it into the political framing.
The IRS still hasn't issued definitive guidance on whether Direct Primary Care subscriptions even qualify as HSA-eligible expenses. So you can deposit money into an account, but the rules around what people can spend it on for actual day-to-day primary care remain genuinely ambiguous. That's not a solvable problem by executive order. It requires regulatory action that nobody in this debate is talking about.
And the geography problem is real. DPC practices are concentrated in urban and suburban markets. Rural communities, which are disproportionately uninsured or on high-deductible ACA plans, largely don't have DPC options to spend that money on even if the accounts existed tomorrow. Direct-to-patient doesn't mean accessible-to-patient. Those are different things.
The underlying diagnosis is correct. ACA subsidies make premiums affordable but leave people facing $3,000 to $8,000 deductibles that function as a wall between them and actual primary care. The insured-but-can't-afford-to-go-to-the-doctor problem is real and underexamined. But the leap from identifying that failure to HSAs-fix-it skips a lot of infrastructure that doesn't exist yet.
I went deep on exactly this tension when analyzing Mark Cuban's version of the same proposal.

The Hinton radiology prediction from 2016 is the canonical example here, and it aged badly in a very specific way. Radiology starting offers are now commonly above $600K, AI reads are additive volume, not replacement volume.
But the more interesting downstream effect nobody is tracking is what happens to primary care compensation as the same AI tools get deployed there. Abridge, Nuance DAX, ambient documentation, these are freeing up enough cognitive bandwidth that risk-bearing PCP platforms are already posting $700K-$900K for top-quartile earners. The shortage narrative and the AI replacement narrative are colliding in a way that actually compresses the compensation gap between specialties, not by destroying radiology but by lifting primary care.
And that compression is coming from multiple directions at once, TEAM bundles hit ortho and spine starting January 2026, Medicare PFS conversion factor cuts are cumulative and real, the IMG pipeline is under structural pressure. Radiology and primary care are the beneficiaries, not the casualties.

Breaking news: The Trump administration accidentally exposed the Social Security numbers of health care providers in a database powering a new Medicare portal, The Post found.
Officials say they are addressing the problem. https://t.co/IDFGZ227fP
946,801 Medicare beneficiaries had their MBIs exposed in a single five-day window during the MOVEit breach in 2023, and that number keeps getting cited as an anomaly when it's actually a preview of what happens when any system still routes identity verification through plaintext identifiers stored in centralized databases.
Provider SSNs in a Medicare portal is the same structural failure (different population, same architecture) as every member ID breach before it. The credentials are readable, they're stored, and that means they're leakable. Fixing the portal's access controls doesn't touch that underlying design.
What I've been arguing is that the healthcare system needs to stop treating these events as security lapses and start treating them as receipts from a bad architecture. Zero-knowledge proof systems, the same cryptographic approach securing Zcash and Ethereum transactions at scale, make the stolen credential worthless because the verification process never requires the actual identifier to be transmitted or stored in readable form. The proof travels, not the secret.
CMS currently spends roughly $500 million a year on fraud prevention without addressing that core design flaw. That budget is essentially funding better locks on a door that was built without walls.

Revolut just moved the IP of banking into a model.
Trained on 24 billion banking events in 111 countries.
One foundation model replacing six separate ML systems.
Credit scoring: +130%
Fraud recall: +65%
Marketing engagement: +79%
The model is the new moat.
Revolut's numbers are genuinely impressive, and fraud recall at +65% is hard to dismiss. But Revolut is also a single institution with a unified data environment, engineering talent most health systems will never have, and no FDA oversight of their credit scoring outputs.
The dynamic flips completely in healthcare. A mid-sized health system typically has one or two people with real ML background. They cannot build or maintain a foundation model, cannot validate it across patient populations, and cannot document it for clinical decision support oversight under FDA's SaMD framework. The model being good is necessary but nowhere near sufficient.
That's actually the argument I've been making: in banking, the model can be the moat because deployment infrastructure is relatively standardized. In health AI, the infrastructure between the model and clinical use, validation pipelines, governance documentation, drift detection, EHR integration, is where the durable value accumulates, precisely because no single institution can build it and the foundation model providers won't build it for them. https://www.onhealthcare.tech/p/the-ai-clinical-infrastructure-company?utm_source=x&utm_medium=reply&utm_content=2048426911970288077&utm_campaign=the-ai-clinical-infrastructure-company
I continue to maintain genomics is a bit like AI in the 2010’s — a small number of people have been going at it for many years, and it’s only now becoming obvious to the broader world + Silicon Valley the profound impact it will have.
The sequencing cost story is compelling and real. A genome that cost three billion dollars in 2003 now costs under a thousand and takes hours. That curve looks a lot like compute costs dropping before the deep learning wave hit.
But here is where the analogy gets harder. When compute got cheap, the bottleneck shifted to data and then to models, and both of those were solvable with more compute and more researchers. In genomics, cheap sequencing moved the bottleneck to interpretation, and that bottleneck does not yield to the same tools. A typical whole genome sequence returns three to four million variants per patient. Roughly half the variants in disease-linked genes have no clear clinical meaning under current guidelines. They sit in a category called variants of uncertain significance, which is not a stepping stone to answers, it is a wall. You can't treat uncertainty.
The regulatory and workflow layer compounds this. Tools like AlphaMissense and SpliceAI have moved the science forward on variant pathogenicity, but a research tool and a clinical tool are different objects under FDA oversight. The path from one to the other runs through reimbursement, hospital IT systems, and clinical workflow integration, none of which respond to algorithmic progress alone. Most companies in this space have underestimated exactly that gap.
So the analogy holds in one direction and breaks in another. The "world waking up" moment in AI came when results were visible and fast. Clinical genomics results are slow, often ambiguous, and carry costs on both sides of error, a missed diagnosis and an unneeded surgery are both bad in ways that a wrong image label is not. What does the "ImageNet moment" for genomics actually look like if the output is a clinical recommendation with asymmetric stakes?

I guess this was the plan all along: have ACA collapse on itself because Americans can’t afford to pay the premiums without federal assistance. Tens of millions will end up without healthcare.
I gifted this so you can read it.
https://t.co/WitaBdWnvm
Structural collapse by design is actually the more precise framing here, and my research on the 2025 premium surge points to the exact mechanism: when subsidies cover the full premium for most enrollees, price sensitivity drops to zero, which means insurers stop competing on cost and start optimizing for the federal government as their real customer. The market can't self-correct under those conditions (and Oscar, Bright Health, Clover all learned this the hard way, spending billions trying to crack unit economics that the regulatory architecture makes structurally impossible).
So the premiums aren't just high because healthcare costs rose. They're high because the subsidy design itself removes the only feedback loop that would normally discipline price increases. Which raises the question of whether letting the enhanced tax credits expire actually fixes anything, or just shifts who bears the pain while the underlying...

i can't believe they're really gonna do it again
the last time stripe shipped a primitive this big, it literally birthed modern saas.
shopify, substack, gumroad, all your fav indie hackers...
they exist only because stripe's payments api let them easily accept money with a few lines of code
yesterday stripe shipped the spending version.
anyone can now get an agent to spend money on their behalf.
if stripe's payments api created saas, this spending api creates autonomous commerce:
a new category of businesses that run on agents buying, booking, restocking, and paying on your behalf
to make that concrete for you, here's some cool ideas you can build now:
1. ai ad managers. you connect your meta, google, and tiktok accounts, set a monthly budget cap, and an agent runs your entire paid strategy.
2. ai procurement agents for ecommerce. they monitor supplier prices, auto-order when costs hit your threshold, send you a morning summary of what they bought and why
3. ai travel agents that actually work. they search, compare, book, and pay within your budget rules. no more toggling between 6 tabs to save $40 on a flight
4. ai bookkeeping agents. they handle the recurring operational payments your business already makes every month (contractor invoices, ad account top-ups, subscriptions, etc)
the 18-month window after a new primitive ships is historically when the category-defining companies get built
if i was building right now i'd pick one of these, find the narrowest possible version of it, and ship before it closes
generational opportunities here imo. good luck!
The Stripe framing is compelling, but the harder problem in regulated industries is not spending authority, it is payment receivability at the API layer. An agent that can spend is still hitting a wall the moment it needs to pay a credentialed provider, a hospital system, or a payer network, because those endpoints don't accept programmatic settlement. They batch, they invoice, they reconcile quarterly.
And that's exactly the bottleneck I've been writing about in healthcare specifically.
The real unlock isn't giving agents a card. It's embedding payment settlement into the HTTP call itself, so that a radiology inference engine or a remote monitoring platform can charge and collect the moment a service is rendered, without a billing department, a clearinghouse, or a 90-day revenue cycle standing between the transaction and the treasury.
But the Stripe spending API and the x402 protocol are actually solving from opposite ends of the same problem, one gives agents the ability to pay, the other gives services the ability to charge autonomously, and neither alone closes the loop.
In healthcare, where both sides of that transaction are heavily intermediated, you need both primitives working together before autonomous commerce actually runs. That's the structural gap I tried to map out here: https://www.onhealthcare.tech/p/reinventing-healthcare-payments-a?utm_source=x&utm_medium=reply&utm_content=2049911241003430055&utm_campaign=reinventing-healthcare-payments-a
A baby was born with one genetic typo that would kill him. Doctors had six months. They read every letter of his DNA, found the typo, and wrote a drug to fix only that letter. He got the first dose last year. He's the first person ever treated with a medicine made just for him.
What happens next is the part most people miss: that single case just became natural history data for every future patient born with the same typo.
Under the FDA's Plausible Mechanism Framework, published in early 2026, that one patient, his baseline, his progression, his response, can anchor a regulatory submission for the next child born with that same edit. The PMF allows a single well-controlled investigation plus confirmatory evidence to meet the bar for substantial effectiveness. A cohort of one, documented with enough rigor from day one, is no longer outside the approval system. It is the approval system, if the natural history was treated as a core scientific asset rather than a footnote.
The harder question is whether the team that saved this boy built that record in a way that future programs can actually use, because most early-stage gene therapy programs still treat natural history collection as paperwork rather than a platform asset that compounds in value every time a new variant gets added under the same IND.

Harvard just tested AI against ER doctors in real emergency triage.
AI nailed diagnoses 67% of the time.
Doctors: 50-55%.
Especially strong with minimal info - exactly when every second counts.
A “profound change” in medicine is here.
Triage accuracy is the compelling part of this finding, but it's probably not where the legal pressure lands first.
The clinical domains where malpractice liability is most likely to crystallize are ones with cleaner documentation trails and binary outcomes: a mammogram read, a skin lesion classified, a retinopathy screen missed. Emergency medicine is messier (chaotic intake, limited history, competing priorities), which makes causation harder to establish in court even when the performance gap is real.
What I'd watch is how malpractice insurers respond to data like this. They don't need a successful lawsuit to start adjusting. They need a credible performance differential and a documented, FDA-approved tool that was accessible and not used. That actuarial logic moves faster than litigation.
The analogy that keeps coming up in my research is failure to order standard imaging. Courts didn't wait for a wave of cases to establish that missing an obvious CT was actionable. They needed one solid causal chain. Emergency AI triage may reach that threshold sooner than people expect, precisely because the time-pressure framing makes the counterfactual easier to argue.
The physicians who think "we're not ready to be held liable for this" may be right today and wrong within a surprisingly short window.

Experimentally Validated Deep Learning Control of Protein Aggregation
1. The study introduces AggreProt, a deep neural network that predicts residue-level aggregation-prone regions (APRs) directly from protein sequence, and then uses those predictions to design mutations that https://t.co/aFeDBCOxfI
The discriminative-versus-generative distinction your article draws is exactly what makes this AggreProt work interesting to sit next to the Profluent thesis. AggreProt is doing something genuinely useful, predicting and then suppressing aggregation-prone regions, but it's still operating on the filter side of the ledger: given a protein that exists, make it behave better. That's a meaningful capability, especially for biologics manufacturing where aggregation is a persistent cost and safety headache.
The downstream implication worth adding is that discriminative tools like this don't compete with generative protein design so much as they become a dependency of it. If Profluent's ProGen3 is writing novel sequence space that evolution never reached (and that's the whole claim), then aggregation prediction and stability engineering become mandatory post-generation checkpoints, not alternatives to generation. The closed-loop training pipeline described in the Lilly deal structure, design then synthesize then test then retrain, probably needs something like AggreProt baked into the loop rather than applied after the fact, because a generative model optimizing for function alone will almost certainly keep rediscovering aggregation-prone sequences unless solubility constraints are part of the training objective.
What that implies for the competitive structure is that best-in-class discriminative tools don't lose value when generative platforms scale. They get absorbed into the pipeline, either as commercial API calls or as acquired capabilities (and acquisition pressure on tools companies like this one may be a quiet signal worth watching as foundation-model platforms try to close their loops).

Cigna is abandoning the ACA health insurance marketplaces by the end of the year, following in Aetna’s footsteps. Insurers have shown, time and again, they will bail on the ACA market if people are too sick. @TaraBannow reports: https://t.co/kW6Cq06Haa
The harder question is whether "too sick" is the real reason, or whether it's that the risk-sharing backstop was never trustworthy enough to justify staying.
When I looked at the CO-OP collapse, the pattern wasn't insurers fleeing sick enrollees. It was insurers fleeing unpaid receivables. Twenty of 23 CO-OPs are gone (most had workable member pools) because they booked risk corridor claims as assets and the government paid twelve cents on the dollar. The market failure was a capital structure failure, not a morbidity failure.
Cigna and Aetna are bigger, so they can absorb the loss and walk. Smaller players couldn't. Same exit, different mechanism.
What that means for the next entrant is the real open question. If you're a venture-backed, risk-bearing carrier pricing ACA lives right now, you're not just modeling member health. You're modeling political commitment to payment, which is a different kind of math entirely.

Proud to introduce the Stop Deadly Denials Act with @RepJayapal.
This will stop Medicare Advantage from using prior authorization to delay or deny critical care and prevent A.I. from overriding Medicare Advantage or Medicare and denying treatment. https://t.co/JlsPsNxHjE
The AI oversight framing is legitimate and worth taking seriously, but the legislation stops at the wrong layer of the problem.
Prior auth in Medicare Advantage isn't primarily a clinical gatekeeping tool, it's one of the few prospective fraud controls the program has. Medicare fee-for-service runs 6-8% improper payment rates on $450 billion in annual spending precisely because it lacks these checkpoints, commercial plans lose 1-3% for reasons that are structural, not accidental. Wrote about the full mechanism here: https://www.onhealthcare.tech/p/prior-auth-and-denials-are-healthcares?utm_source=x&utm_medium=reply&utm_content=2049873556356354071&utm_campaign=prior-auth-and-denials-are-healthcares
Removing AI-assisted review without replacing it with equivalent fraud detection is how you replicate the pay-and-chase vulnerability that costs Medicare tens of billions every year, the fraud and the access debates look separate but they're downstream of the same structural gap.

Commentary:
🔸 “2026 is off to a strong start, we delivered 56% revenue growth in the first quarter and raised our full-year revenue guidance by $2 billion.”
🔸 “A key milestone was the U.S. FDA approval of Foundayo—the only approved GLP-1 pill that can be taken any time of day, without food and water restrictions.”
🔸 “Foundayo will meaningfully expand the number of people who can benefit from GLP-1s.”
The oral approval is the headline but the more telling number is realized prices down 13% YoY while volume grew 65%, that gap is going to widen, not close, once Foundayo scales.
The thing most coverage is missing: oral GLP-1 approval doesn't just expand the patient pool, it accelerates the commodity clock. Written about this at https://www.onhealthcare.tech/p/the-peptide-economy-vs-the-healthcare?utm_source=x&utm_medium=reply&utm_content=2049803153877664251&utm_campaign=the-peptide-economy-vs-the-healthcare, the argument being that oral entry could push addressable patients up 40-60% while compressing injectable pricing faster than most models assume, because a pill format lowers the friction that was quietly holding price floors up. No cold chain, no injection training, no specialty pharmacy, which means the moat around the molecule shrinks and the moat around data and trial evidence grows.
Lilly's real position here is the STEP-equivalent trial estate and the FDA clearance record, not the semaglutide structure or even the tirzepatide structure once biosimilar timelines hit 2031-2033. The 82.6% gross margin looks durable now, but oral formats invite generic competition in ways that injectables historically delayed.
The guidance raise is real and the quarter is strong, no question. The harder question is what the margin curve looks like in year three of oral GLP-1 availability when two or three competitors have their own pills and the price decline that's already at 13% starts moving toward...
Google DeepMind just quietly released research that changes how we think about AI in healthcare.
They built an “AI co-clinician” and tested it against real doctors and GPT-5.4 in blind evaluations.
Here is what the numbers actually say:
In 98 realistic primary care queries, https://t.co/3ITjHXGd71
Benchmarks like this are the ones worth watching, but 98 primary care queries is still a long way from what actually breaks clinical AI in practice.
The harder test isn't whether a model outperforms a physician on a well-formed query. It's whether it can maintain calibrated uncertainty across a diagnostic workup where the presenting picture keeps shifting, the labs come back equivocal, and the prior probability changes with each new data point. That's the Bayesian inference problem, and next-token prediction architectures aren't built for it regardless of how the leaderboard looks.
I wrote about this specific gap at https://www.onhealthcare.tech/p/clinical-reasoning-vs-documentation?utm_source=x&utm_medium=reply&utm_content=2050153260515045817&utm_campaign=clinical-reasoning-vs-documentation after working through the ED chest pain case that the literature keeps using as the canonical example, partly because MedQA-style evals, which this kind of blind comparison descends from, were already being critiqued as nearly useless for measuring actual reasoning capability.
The 12 million misdiagnosed adults per year in the US aren't being failed by documentation. They're being failed at inference.
"At the Veterans Health Administration, we have the exquisite gift of a hospice unit, a place to care for veterans when time is short. We care for the sons of mothers who can no longer be here to care for them."
In #APieceofMyMind, a #palliative care #physician reflects on https://t.co/cUwK2T9J2u
End-of-life care at its most human. What the VHA hospice unit describes, that bond between veteran and caregiver stepping into an absent mother's place, is exactly the relational core that gets lost when you zoom out to the policy level.
And the policy level right now is not kind to that picture. The FY 2027 CMS proposed rule and Operation Never Say Die together expose what happens when the per diem payment structure gets treated as an arbitrage opportunity rather than a care financing mechanism. For-profit hospices averaged 167% higher non-hospice spending per day than nonprofits in FY 2024 (up from 60% in FY 2022), which means the financial incentive is increasingly to enroll patients and then bill outside the benefit rather than deliver the kind of presence this physician is describing. The fraud doesn't just steal money. It crowds out the infrastructure that makes moments like this possible.
The VHA hospice unit exists precisely because it's insulated from those per diem incentives. The rest of the industry isn't, and CMS's new SSVI scoring system is the first serious attempt to make that gap visible at scale. More on the structural collision between these two realities here: https://www.onhealthcare.tech/p/the-hospice-industries-fraud-crisis?utm_source=x&utm_medium=reply&utm_content=2049881462581744011&utm_campaign=the-hospice-industries-fraud-crisis
Ovaries age 2.5x faster than any other organ. That single fact should've attracted billions in venture capital a decade ago.
It's finally happening. @Columbia's VIBRANT trial: rapamycin cut egg loss 70%. @GametoGen raised $127M. @ARPA_H committed $10M. @altos_labs ($3B) is now https://t.co/n7brKYPvLp
The capital formation story here is real, but the expected value math on these programs is trickier than the headline numbers suggest.
Rapamycin's mechanism is reasonably well-supported by human genetic data on mTOR pathway variants and reproductive longevity, which matters a lot for probability weighting. That's not a trivial advantage. Programs with that kind of genetic backing run roughly twice the approval odds compared to correlative preclinical evidence alone.
What concerns me is how the market is pricing the endpoint problem. "Egg loss reduction" is a surrogate, and the FDA has no established approval pathway for ovarian aging as an indication. That regulatory ambiguity should be compressing terminal value estimates pretty aggressively, but the $127M raise suggests investors are discounting it less than they probably should.
The deeper issue is CAPM misfit. The risk here is almost entirely idiosyncratic scientific and regulatory risk, not market-correlated risk, so standard discount rates almost certainly overpenalize the long-duration biology programs and underpenalize the endpoint uncertainty. Those two errors cut in opposite directions and they don't cancel cleanly.
A decade of underinvestment also means the historical clinical success rate databases for this indication are thin to nonexistent. You're essentially building a prior from scratch, which means whatever base rate an investor plugs into their model is doing a lot of unjustified work.

Using AI for every task might save time, but it could come at a cost. New research suggests people who passively rely on AI at work may feel less confident in their own thinking and reduced ownership over their ideas. Learn more: https://t.co/eSENOM8s4Q https://t.co/HIFTz2Dh9m
This maps onto something I found when looking at clinical AI deployment. The studies that actually show durable value aren't the ones where AI replaces judgment, they're the ones where humans stay in the loop. The DeepSeek-R1 critical care data I analyzed is a good example: the model alone hit 60% diagnostic accuracy, residents alone hit 27%, but residents using AI hit 58%. The collaboration ceiling is real, and autonomy erosion is probably why full automation underperforms over time.
For health tech investors, this is exactly why I'd be skeptical of any company pitching full clinical automation. Confidence in one's own reasoning isn't a soft benefit, it's what keeps the human-AI system calibrated. The moment clinicians stop owning their decisions, you lose the error-correction layer that makes collaboration architectures outperform solo AI in the first place.

As I mentioned before, I am now sharing an example from GPT-5.5 Pro, also featured by OpenAI, that really left me stunned by what it is capable of in biomedical science. (full report on the website I created with Codex, link in the thread).
To push GPT-5.5 Pro hard, I uploaded a https://t.co/2qdsHPZClM
The benchmark numbers are where I'd slow down here. The Dyno Therapeutics eval cited in OpenAI's launch materials showed best-of-10 submissions reaching the 95th percentile of human experts on sequence-function prediction. Impressive number, but OpenAI had training-time knowledge of the task structure behind BixBench and LABBench2. Self-reported evals against benchmarks you helped design are not the same as independent replication, and "stunned by capability" is exactly the reaction that gets reproduced in press cycles before the harder validation work gets done.
What I've been tracking more closely is what sits underneath the model: the Codex Life Sciences plugin connecting to 50+ databases across human genetics, protein structure, functional genomics, and clinical evidence. That infrastructure, priced at zero during the preview phase, is doing something more commercially significant than any single capability demonstration. Enterprise pharma buyers getting free access for 6 to 12 months will reset their willingness-to-pay benchmarks for the entire category of biotech software, including the lit-review and protocol design tools that often get demo'd in exactly the kind of showcase you're describing here.
The question I'd push on is whether the underlying analysis you ran depended on data that is publicly indexed, or whether there was something proprietary in the upload that the model couldn't have approximated through its training corpus. That distinction matters a lot for figuring out what the capability demonstration actually shows.

In the rapidly evolving oncology landscape, NCCN guidelines and FDA approvals often change after a patient’s initial genomic test. To bridge this gap, Refresh provides automatic updates to therapy options for patients when guidelines change or FDA-approved therapy options emerge https://t.co/qRO0Q1PCOn
The 95% unmodified approval rate I found when looking at AI-generated treatment plans is what makes "automatic updates" a genuinely hard problem here, not a solved one. If clinicians are rubber-stamping AI recommendations at that rate, then the question of what validation happened before the update propagated to the patient record becomes load-bearing in a way the "automatic" framing quietly sidesteps. A retrieval index that refreshes when NCCN guidelines change is a different system post-refresh than it was pre-refresh, and current regulatory frameworks have no clean mechanism for that, because clearance was point-in-time and the changed system was never the thing that got cleared. So who confirmed that the updated therapy surface behaves the way the original validated version did, and does that confirmation happen before or after the recommendation reaches a clinician who is, statistically, very likely to approve it without modification?

I find this FDA argument quite dogmatic.
"Maximizing benefit of each therapy" is kind of saying we want to wait until full blown tumor resistance to a particular therapy before moving on to the next one.
There is actually no scientific basis that this is the best way to treat https://t.co/gJuNcMXgcx
Right, and the sequencing dogma you're poking at is itself a latency artifact, the clinical trial system was built around discrete phases partly because regulators could only process batched data, so "maximize each therapy first" became the protocol norm by default. The biology never actually demanded it.
What I'd add: FDA's new real-time trial program makes this even more exposed. Once you're streaming continuous efficacy and resistance signals to the agency, the scientific justification for waiting until full progression before switching evaporates in real time, not at the next data cut. The phase gate isn't just a financing construct, it shaped clinical decision-making too, and that's the part oncologists should be arguing about loudly.

Randomized trial of an AI therapy chatbot on Mexican women found “improved mental health by 0.3 SD over 6 months with no evidence of an increase of severe cases; improved sleep, healthful behaviors, daily functioning & labor market outcomes”
Big results for a cheap intervention. https://t.co/KZTKVcdHCj
Six months of follow-up, labor market outcomes, sleep, functioning, all moving in the same direction from a single low-cost intervention. That's a rare pattern to see hold across that many domains simultaneously.
But here's where I'd push on the framing: 0.3 SD is a real effect size, the question procurement teams and investors should be asking is whether this trial design would survive the scrutiny that health system contracting now demands. When I looked at the UCLA ambient AI scribe study for a piece on clinical AI investment signals, the specific time savings mattered less than the fact that the evidence came from a randomized trial across 14 specialties, because that methodology set the template health systems will now require from every vendor who walks in the door.
The same logic applies here. A 0.3 SD improvement from an RCT with six-month follow-up and labor market endpoints is a completely different commercial asset than the same number from a before-after analysis or a vendor-provided case study, it changes what payers and procurement teams can actually do with the finding.
The harder question is whether the trial infrastructure that generated this result scales, meaning can the research partnership model that produced clean RCT evidence for a Mexican women's mental health population transfer to the messier deployment contexts that enterprise buyers actually care about, or does the evidence quality degrade the moment you're outside a controlled study setting?

Chatbots are helping techies come up with daring treatment plans for themselves or loved ones facing dire medical diagnoses. But those plans can be risky and cost hundreds of thousands of dollars to put into action.
More in our latest Big Read: https://t.co/ZlgbkhGTGg
The question this raises that nobody seems to be asking: who bears the cost when the daring plan doesn't work?
What I found when looking at this pattern is that the financial risk starts much earlier than the six-figure treatment. Patients uploading routine lab results to consumer AI platforms routinely receive six to eight supplement recommendations before they've even seen a specialist, each interaction building what behavioral economists call escalation of commitment, where the initial purchase justifies the next test, which justifies the next consultation. By the time someone is pricing experimental protocols, they've already been primed through dozens of smaller AI-driven decisions to trust the machine over watchful waiting.
The mechanism is algorithmic, not financial. The AI has no incentive to bill you, it simply optimizes for actionable output over clinical restraint, and that bias compounds across every interaction.
Dire diagnoses are the visible end of a much longer chain.

GPT-5.5 is on par with Claude Mythos
- GPT-5.5 average pass rate of 71.4% (±8.0%)
- Mythos Preview 68.6% (±8.7%)
- GPT-5.5 solved a task that takes a human expert ~12 hours in under 11 minutes at a cost of $1.73 https://t.co/SuZtinoNTn
The benchmark parity is interesting, but it's the wrong frame for healthcare security specifically. Mythos Preview produced working exploits 181 times on Firefox 147 JavaScript engine benchmarks where Opus 4.6 achieved near-zero success. That's not a capability gap that aggregate pass rates capture. What matters for clinical infrastructure isn't average task performance, it's whether a model can autonomously discover zero-days in the legacy systems that hospitals can't patch because the FDA's premarket cybersecurity requirements under Section 524B apply to new devices, not the installed base. GPT-5.5 at benchmark parity with Mythos means adversary access to that exploit-generation capability is arriving faster than Anthropic's own red team estimated, and they already put that window at 6 to 18 months. Healthcare still has no seat in Project Glasswing. That gap won't close by comparing pass rates.

An optimized adenine base editing strategy can repair the “untreatable” 1717-1G>A #CysticFibrosis mutation in cells and organoids with potentially promising efficiency rates and little off-target editing, according to new work in @ScienceTM. https://t.co/lVRtQXhHoU https://t.co/HvRDLsY2ow
The efficiency and off-target profile here will matter a lot when the FDA's new NGS safety guidance hits IND submissions. Pre-IND off-target analysis using biochemical and cell-based assays is now a first-order requirement, and base editors get a different treatment than Cas9 under that framework, which actually works in favor of results like these.
The bigger story though is how this maps to the Plausible Mechanism Framework. A defined genetic abnormality, a targeted correction, organoid-level target engagement data. That's three of the five PMF elements already taking shape in preclinical work. For a mutation with essentially no approved treatment and a patient population too small for conventional trial design, that pathway starts to look real.
The question I keep coming back to: how many CF sub-mutation programs are sitting on similar preclinical data right now, not moving forward because the commercial math never worked under the old approval logic? The modular variant logic changes that calculation pretty substantially.

The o-1 reasoning model (text only, from @OpenAI, released, Sept 2024) exceeded performance cf GPT-4 and physicians for clinical vignette management reasoning and in a real-world emergency department assessment for initial triage @AdamRodmanMD https://t.co/X5eKvyBXBG
The benchmark that matters isn't the one they ran, it's the one they didn't. Clinical vignettes and structured triage scenarios are exactly the contexts where sophisticated pattern matching is indistinguishable from reasoning, they're curated, representative, and clean. Apple's methodology for probing LLM reasoning did something more adversarial: preserved the underlying logical structure while changing surface features, and performance collapsed. That's the test medical AI actually needs to pass, because atypical presentations are precisely what breaks pattern-dependent systems, and "exceeded physician performance" on vignettes tells you almost nothing about what happens when the presentation doesn't look like training data. The reasoning-versus-pattern-match debate isn't academic hairsplitting. It determines whether you trust this technology for the 3am presentation that doesn't fit the textbook. https://www.onhealthcare.tech/p/the-hippocratic-method-and-the-future?utm_source=x&utm_medium=reply&utm_content=2049918454648689112&utm_campaign=the-hippocratic-method-and-the-future
Not something you'd see everyday—changing the alphabet of life.
All of life organisms are are built from 20 amino acids. Now genAI is enabling life to be built with 19 amino acids, making isoleucine dispensable. @ScienceMagazine
https://t.co/7CBn0Xhuxs https://t.co/tkxtCrFx9Y
The isoleucine finding is striking, and the compression direction matters as much as the expansion direction.
When I was writing about Profluent's closed-loop pipeline for https://www.onhealthcare.tech/p/profluents-225b-lilly-deal-and-why?utm_source=x&utm_medium=reply&utm_content=2049953880663097757&utm_campaign=profluents-225b-lilly-deal-and-why the point I kept returning to is that the search space generative models open is genuinely discontinuous from what evolution explored, and dispensing with a canonical amino acid is exactly that discontinuity made concrete. Evolution never had a reason to remove isoleucine. It had no selection pressure toward minimalism in the alphabet itself.
What the Science finding adds to the protein design conversation (and what I think gets underweighted) is that subtraction expands design space in ways addition alone does not. Fewer building blocks with defined function means the model has harder constraints to satisfy, which tends to produce more generalizable sequence grammars. That is the same logic behind why sparse training signals often outperform dense ones in language models.
The regulatory implication is the part nobody is pricing yet. A therapeutic protein built on a compressed amino acid alphabet will face immunogenicity review frameworks that were written assuming the canonical 20. Pharma has had better discriminators for thirty years (the usual story), but the actual bottleneck coming is that the regulatory infrastructure for evaluating genuinely non-natural protein biology simply does not exist at scale.
Subtraction might get us there faster than addition ever could.
The best medical societies aren't waiting to see how AI shapes clinical practice. They're shaping it.
We're partnering with @AmerUrological to bring AUA Clinical Practice Guidelines and Clinical Consensus Statements into OpenEvidence answers. Urologists and other clinicians will https://t.co/sQJXxqKkXm
The AUA partnership is worth watching closely, because it reveals something about where the real monetization pressure lands.
Medical societies embedding their guidelines into AI decision support tools get visibility and clinical authority reinforcement. OpenEvidence gets credentialed content that strengthens its FDA positioning as a clinical information tool rather than a diagnostic device. That distinction matters enormously. Software as Medical Device classification would impose compliance costs that effectively kill a freemium model before it scales.
But the downstream consequence most people aren't discussing: as more societies bring their guidelines into platforms like this, the content itself becomes a negotiating asset. AUA today, ACC tomorrow, IDSA the week after. At some point OpenEvidence has enough specialty coverage that health systems start asking whether they still need UpToDate licenses. That's when enterprise contract conversations get serious, and that's when the $500K to $2M per health system pricing the company will eventually need to defend actually becomes credible.
The societies, though, are trading something they may not fully price yet. Their guidelines inside an AI query interface generate behavioral data about how clinicians actually use recommendations at the point of care. Who queries which guideline, under what clinical context, how often recommendations get overridden or accepted. That query data has real value to insurers, device manufacturers, and yes, pharmaceutical companies. Whether society partners share in that value, or simply provide the content that makes it possible, is a negotiation most of them haven't had.
I mapped out the full monetization architecture here, including where society content fits into the pharmaceutical partnership and data revenue streams: https://www.onhealthcare.tech/p/openevidence-business-case-monetization?utm_source=x&utm_medium=reply&utm_content=2049938297309503737&utm_campaign=openevidence-business-case-monetization
Love seeing Silico (@GoodfireAI ) used to probe our EchoJEPA's representations! this is exactly the kind of interpretability work that's been missing for JEPA-style models.
One thing that makes EchoJEPA particularly interesting to interpret: unlike MAE-based approaches, it never https://t.co/cCW0bdPoN2
The shift from MAE to JEPA changes what you're even looking for inside the model, the latent space is structured around prediction targets rather than pixel reconstruction, so standard feature attribution breaks down in ways that aren't obvious until you're already inside the weights.
That gap is part of what I was tracking when I looked at Goodfire's work on Arc Institute's Evo 2, a genomic model where the internal representations encoded biology that hadn't been named yet. The method mattered: 58% hallucination reduction came from targeting internal model mechanisms, not post-hoc filtering. With JEPA-style models, I'd expect the same logic to apply but with even less prior work on what the features should look like.
Which raises the question: when you're probing EchoJEPA with Silico, what's your baseline for knowing whether a feature is clinically...

Since joining @GoogleDeepMind I’ve dreamt for a decade that AI can give clinicians superpowers: amplifying reach as an always-available, trustworthy member of the care team. Delighted to share our strategic research initiative at @GoogleDeepMind towards this vision: AI https://t.co/bZJqaTT6EN
The "always-available care team member" framing is exactly where the real design work lives. But the hardest part isn't building the AI, it's getting the delegation model right. Who owns the decision, who gets the alert, and what happens when the AI escalates something the attending would have dismissed?
The mental model I've found most useful: treat clinical AI the way we've learned to integrate pharmacists and PAs, defined scope, clear escalation paths, audit trails. And the infrastructure question that rarely gets enough attention is where the data lives. Federated learning protocols that improve models across institutions without pooling patient records are what make "trustworthy team member" a real claim rather than an aspiration.
The amplification vision is right. The organizational wiring to make it real is still the harder problem.

Amazing story here about how the Mayo Clinic developed an artificial intelligence (AI) model that can detect pancreatic cancer on routine abdominal CT scans 3 years before clinical diagnosis.
It identifies subtle signs of disease before tumors are even visible.
Three years of lead time on pancreatic cancer is the kind of number that reframes what "early detection" even means, and it points directly at the infrastructure problem that gets underestimated in most of these announcements.
The Mayo model works on CT scans, which is a single modality, and that's genuinely impressive. The harder question is what happens when you try to integrate that signal with a patient's genomic risk profile, their longitudinal biomarker trends, their environmental exposure history, all sitting in different systems that weren't built to talk to each other. I wrote about exactly this bottleneck at https://www.onhealthcare.tech/p/the-pre-cure-revolution-how-ai-powered?utm_source=x&utm_medium=reply&utm_content=2049956512328712404&utm_campaign=the-pre-cure-revolution-how-ai-powered, where EHR interoperability failures aren't just a technical inconvenience but the actual ceiling on how far detection models like this one can scale clinically.
The detection capability is arriving faster than the infrastructure required to act on it systematically.
And there's a payer dimension nobody in these announcements wants to talk about: a model that flags pancreatic cancer three years early is only clinically useful if the surveillance and intervention protocols that follow are reimbursable, which right now they often aren't, because insurance models are still structured around treating confirmed disease rather than managing probabilistic risk. The AI is outrunning the payment architecture, and that gap is where most of these breakthroughs quietly stall between the research paper and the standard of care.
To be fair, Medicare grossly underpays doctors while paying hospitals close to market rates. So while 300% Medicare charged by a hospital is unacceptable, it’s not the case for physicians. If you don’t believe me, just compare reimbursement rate increases over the last 40 yrs
The physician payment piece is real and underappreciated. Medicare's conversion factor has been essentially flat in real terms for decades while practice overhead has compounded. That asymmetry is doing a lot of work in how the delivery system is actually reshaping itself right now.
But the downstream consequence that gets missed is what this payment gap is doing to employment structure. When hospital margins depend on commercial cross-subsidy and physician reimbursement is structurally insufficient for independent practice, physicians consolidate into employed models under health systems, which then use their facility fees to capture the margin physicians alone couldn't generate. The 340B program, hospital outpatient department billing, site-of-care differentials, these aren't incidental. They're load-bearing for a system where physician payment was never corrected.
And CMS knows this. The site-neutral payment proposals coming through now are essentially trying to claw back the facility fee arbitrage without fixing the underlying physician payment problem. Which means you get margin compression at the system level without relieving the pressure that pushed physicians into employed arrangements in the first place.
What I found when mapping the Vizient 2026 data is that advanced practice providers now exceed 40% of employed providers, partly because NP reimbursement economics are more favorable under the same broken structure. So the physician payment floor isn't just a fairness problem, it's actively reshaping who delivers care and where.
Whether site-neutral cuts accelerate that substitution or produce something more disruptive to access in thin-margin markets is the question nobody seems to be working through carefully yet.

FDA proposes to exclude semaglutide, tirzepatide, and liraglutide on the 503B bulks list. After careful review, we did not identify sufficient clinical need for outsourcing facilities to compound these drugs from bulk substances. Public comment period now open. Learn more: https://t.co/gEgbnHgMtf
Watched this same sequence play out in real time with peptides: FDA resolves shortage designation, removes the legal basis for compounding, and the volume either migrates to licensed 503B incumbents who already have the API relationships and facility registrations, or it bleeds into gray-market channels with worse safety profiles than supervised compounding ever produced.
The GLP-1 unwind is the structural template I used when modeling what Category 2 peptide reclassification does commercially, because the mechanisms are nearly identical. Shortage resolution triggers the 503B wind-down. New entrants cannot replicate existing outsourcing facility licenses on any relevant timeline, so incumbents like Empower and Olympia absorb the volume that stays legal. And the demand that doesn't stay legal ends up in supply chains where nobody is testing for endotoxins.
That last part is where the public health argument gets uncomfortable for FDA career staff, because 1,000+ adverse events on compounded GLP-1s by mid-2025 came largely from that gray-market migration, and an 8% endotoxin contamination rate in independently tested research-use samples shows the same failure mode repeating on peptides right now.
The "insufficient clinical need" determination here will face the same political pressure the peptide Category 2 placements are facing, especially with the Rogan-to-Kennedy announcement cycle running hot. But political pressure and legal force are different things, and the actual decision architecture runs through formal rulemaking, not podcast clips. I walked through exactly why that distinction matters for anyone trying to time this commercially: https://www.onhealthcare.tech/p/the-category-2-peptide-unwind-how?utm_source=x&utm_medium=reply&utm_content=2049877596427473286&utm_campaign=the-category-2-peptide-unwind-how
Medicare and Medicaid exist to serve real Americans — the elderly, the disabled, low-income families who depend on these programs for basic care.
The new DOJ West Coast Health Care Fraud Strike Force means we are fighting back — hard. Protecting CMS programs is protecting patients.
Fraudsters: the full weight of the federal government is coming for you.
Protecting CMS programs requires more than enforcement after the fact, though. The DOJ's 2024 actions charged 193 defendants in schemes involving over $2.75 billion in false claims, which sounds aggressive until you set it against the $31.70 billion in Medicare Fee-for-Service improper payments recorded in fiscal year 2024 alone. Prosecution is recovering pennies on the dollar.
The structural problem is that fraudsters don't need to outsmart the Strike Force. They just need a stolen member ID, which they can use before anyone knows it's compromised. The MOVEit breach of May 2023 handed them 946,801 Medicare Beneficiary Identifiers in a single attack on a clearinghouse vendor, a third party most beneficiaries have never heard of. That's the architecture working exactly as designed, and enforcement can't patch it.
What the Strike Force can do, enforcement cannot: make stolen credentials worthless. That's the direction this has to go, building verification systems where a fraudster who possesses a member ID gains nothing because mathematical proof of identity replaces the ID itself as the authentication mechanism.
The cryptocurrency world already solved an analogous problem this way, using zero-knowledge proofs to verify transactions without revealing the underlying account data. The same cryptographic layer applied to Medicare verification is the argument I make in the piece below.

California Rep Young Kim says fraud in California continues to grow under Gavin Newsom
“We saw hospice fraud. It is exploding. Hundreds of providers are flagged in LA County. Patients are involved without consent. Medicare billing at double the national average — Governor Newsom, Democrat-controlled Sacramento politicians”
She says trying to undercover and stop fraud is not a Republican “gotcha tactic” she says it’s necessary for a functioning society
“It's about insuring resources, which students, veterans, mothers, and the families in need.
We are paying some of the highest taxes and prices in the nation. So the least we can give is the accountability for Californians, the hard-working taxpayers from their state leaders and the government”
Gavin Newsom will literally never be held accountable. He oversaw the largest theft in history, the worst decline of America’s best state and instead of being punished, he’s going to run for president
Rep. Kim is right that the fraud scale here is real, but the "Sacramento failed to act" frame leaves out something that makes the problem harder to fix than that framing suggests.
California actually passed a hospice licensure moratorium in 2021. That's not nothing. The problem is the enforcement lag between licensing restrictions and Medicare certification, which runs through CMS, not the state. A governor can't revoke federal billing privileges. CMS revoked 220 California hospice approvals in about 10 weeks this year, but that authority was always federal, not Sacramento's to exercise.
The deeper issue your post is circling around isn't really a partisan accountability story. It's a payment structure problem. For-profit hospices are billing 167% more in non-hospice spending per day than nonprofits. That gap widened from 60% in 2022 to 167% in 2024. That's not a Newsom-era trend. That's a per diem payment model that makes enrolling non-dying patients profitable regardless of who runs the state.
One Van Nuys building hosting 197 registered hospice companies didn't happen because Sacramento looked away. It happened because Medicare's billing window opens before state oversight catches up, and nobody closed that federal gap until this year's operation.
Holding Newsom accountable is fair. But if the fix stays at the state level politically, the structural incentive driving this stays untouched.

The Mayo pancreatic cancer story is the one to watch, but the headline buries the real question: what happens when that model gets it wrong in a clinical setting and nobody can explain why?
That's not a hypothetical. It's where every major health system is stuck right now. Detection accuracy without interpretability just moves the liability problem, it doesn't solve it.
Mayo took a financial stake in Goodfire specifically because they see interpretability as a prerequisite, not a feature. 58% hallucination reduction by targeting internal model mechanisms. That's a different approach than post-hoc filtering, and it's the piece missing from most coverage of clinical AI wins.
The deeper bet is that models trained on bio data have already encoded disease patterns we haven't found yet. Early detection is one output. The extraction problem is the bigger one.

Google DeepMind’s real-time video AI doctor is here.
They just introduced AI co-clinician, a triadic care system built to work under a doctor’s supervision during patient care.
The system is built to retrieve clinical-grade evidence, verify it, and in patient-facing simulations https://t.co/6KhksDywSy
Real-time evidence retrieval during the clinical encounter is a meaningful step, but the harder problem sits one layer beneath it: retrieving verified evidence is still a compression task. The system surfaces relevant literature and flags contraindications, which is closer to a sophisticated search function than to probabilistic diagnostic inference.
And that distinction matters enormously for where the value actually accumulates. The 40,000 to 80,000 Americans who die annually from diagnostic error are not dying because their physicians lacked access to a clinical guideline. They are dying because diagnostic reasoning under uncertainty, updating a hypothesis as new findings arrive, is structurally different from retrieving and reformatting evidence. A co-clinician that excels at retrieval still hands the Bayesian updating problem back to the physician.
The "triadic care system under physician supervision" framing is doing a lot of work here. Supervision is the right governance model, but it also signals where the AI's actual competence ceiling sits. Systems designed for retrieval and verification are well-matched to physician oversight because their outputs are checkable. Genuine reasoning AI, the kind that could reduce misdiagnosis rates at the population level, would require oversight architectures we have not built yet, because its failure modes are probabilistic rather than factual.
The CFO model problem compounds this. Health systems will price this tool the way they price ambient scribes, in terms of workflow efficiency and liability reduction, because those are the variables their valuation frameworks can absorb. But the outcome-based ROI from reducing diagnostic error is an order of magnitude larger and currently invisible to that calculus.

Reading this excellent story, it reminds me of another article from @sarahkliff, in that case highlighting doctors taking advantage of another well-meaning federal policy that created an opportunity to get rich inflating medical prices (on COVID testing).
https://t.co/3GJkey7Nq0
The COVID testing arbitrage and the chargemaster story rhyme structurally, but there's a layer in the hospital version that makes it harder to unwind. With COVID testing, you had a relatively discrete policy window, identifiable actors, and a clear moment when the opportunity closed. The hospital charging dynamic is different because the mechanism that creates the incentive isn't a temporary emergency provision, it's baked into how Medicare calculates outlier payments year over year.
What I found when I traced the cost-to-charge ratio from 2000 to 2024 is that hospitals didn't just stumble into charge inflation opportunistically. They built organizational infrastructure around it, dedicated chargemaster specialists, revenue cycle consultants running financial models specifically to calibrate where charges need to land to trigger stop-loss thresholds across both Medicare and commercial payers. That's not exploitation of a policy gap, it's a permanent professional function inside the hospital.
The harder problem is that reforms aimed at one piece of this, CMS updating CCRs more frequently after the early 2000s outlier scandals, for example, didn't stop the overall trajectory. The ratio kept declining because the incentive structure runs through multiple payer types simultaneously. Fix the Medicare side and the commercial insurer reinsurance dynamic still rewards inflation, the hospital adjusts and the cycle continues.

🧬 Big update for https://t.co/jQGK6r8cww
We now visualize structure predictions for almost every known protein — powered by the open AlphaFold Protein Structure Database from @GoogleDeepMind & EMBL-EBI, with confidence-aware 3D rendering.
Hope it helps researchers push https://t.co/iivowNkxEA
Confidence-aware rendering is the right call. But the harder problem is that the confidence metrics developed for monomers don't translate cleanly to complexes, and that gap is now commercially significant.
When I was working through the 31 million complex expansion data, the number that stopped me was 57,000 heterodimers passing high-confidence filters out of roughly 7.6 million candidates. That's under 1%. And the filter itself, ipSAEmin above 0.6, pLDDT above 70, backbone clashes under 10, was calibrated on homodimers, not on the heterodimeric targets that matter most therapeutically.
So a visualization layer that faithfully renders confidence scores on monomers is doing exactly what it should. And when complex predictions start flowing into the same interface, those same colors will carry a different epistemic weight than users expect.
The 1.8 million homodimers are relatively solid. Foldseek Multimercluster compresses them about 8-fold, so the structural diversity is manageable. But heterodimers are where drug discovery actually lives, and the calibration infrastructure for that class is still open territory.
What that means practically: any platform surfacing these predictions to researchers needs a way to communicate not just confidence scores but which confidence regime the structure was scored under. Monomer pLDDT on a complex interface residue is not the same signal. Users will assume it is.

A Maine homecare fraud kingpin was ordered to repay nearly $400K in MaineCare in 2022. He paid back just $13K, then got offered secret-level security clearance by the Department of War in 2025.
His other home care businesses have collected $66M in assistance since 2019, with many failing inspections for shoddy record-keeping. Now he lives in Turkmenistan.
Just another day in Mills’ Maine — where no one gets investigated and working families get screwed.
https://t.co/CmGuuwd4Eh
The Maine case is a clean example of the pattern the OIG exclusion list was never built to catch. It tracks individuals by name and SSN, not by the web of new entities they spin up under family members. So when a kingpin exits one LLC and opens three more, the exclusion check on each new NPI comes back clean.
The $66M figure here is plausible at scale because the state's own incentive to pursue it is weak. When federal matching rates cover 70 to 90 cents of every Medicaid dollar, a state loses maybe $30M of its own budget on a $100M fraud. The math on aggressive enforcement gets hard to justify internally, even before you factor in the legal cost of fighting someone who has since relocated to Turkmenistan.
What the Maine story adds to this is the security clearance angle, which shows the data silos running in both directions. CMS, OIG, DoD, and state corporate registries do not talk to each other. The cross-dataset linkage that would surface "authorized official on four Maine home care NPIs, two failed inspections, restitution default" takes an afternoon to build if someone bothers to join the tables. Nobody did.
The fraud signal lives in the gap between spending records and existence verification. That gap is mostly a political choice about whether to close it.
More on the data architecture behind this and why home health is structurally the highest-density fraud category: https://www.onhealthcare.tech/p/the-data-stack-that-catches-crooks?utm_source=x&utm_medium=reply&utm_content=2048162559136588232&utm_campaign=the-data-stack-that-catches-crooks
Still waiting for Washington State to have the fallout like Minnesota.
Another home care location with over $2.3M in revenue last year with no additional information and a small house… https://t.co/ZQbxpeBnV1
Billing addresses are where the paper trail starts to unravel, and what you're describing in Washington fits a pattern that shows up consistently when you cross physical location data against claim volumes.
A small residential address anchoring $2.3M in annual revenue is exactly the kind of geographic implausibility flag that Census TIGER and HUD housing data can surface programmatically, before anyone has to drive by the house.
The harder problem (and the one that keeps this going state to state rather than staying contained) is that the fraud isn't living in one dataset. The address is suspicious, but it only becomes a case when you link it to NPI registration dates, employee count implied by billing volume, whether authorized officials appear on other entity filings, and whether EVV timestamps actually corroborate the visits being billed.
Washington isn't behind Minnesota because its investigators are slower. It's behind because Medicaid's FMAP structure means states covering 30 cents on the dollar have a genuinely weaker financial incentive to chase the other 70 cents, and that math doesn't change just because the fraud becomes visible.
I went deep on exactly this architecture, including why a van in rural New Mexico that billed 1,006 claims per workday only becomes findable when spending data gets joined against the full provider existence stack, in a piece I published this week: https://www.onhealthcare.tech/p/the-data-stack-that-catches-crooks?utm_source=x&utm_medium=reply&utm_content=2048134720811323398&utm_campaign=the-data-stack-that-catches-crooks
Sophisticated data analytics are transforming how this Civil Division is identifying fraud.
Today, I’m proud to announce we have launched the FOCUS initiative to prioritize partnerships with data miners using cutting-edge tools to uncover misconduct across federal programs.
We’re committed to working with the most effective partners in the fight against fraud.
The FOCUS framing is interesting but the constraint worth watching is where the signal actually lives, and right now it's in the gap between spending data and provider existence verification, not in algorithmic sophistication.
The newly released HHS Medicaid spend file (227 million rows, NPI x HCPCS x month, 2018 through 2024) becomes genuinely powerful only when joined against NPPES registry formation dates, OIG exclusion lists, and state corporate filings, because the fraud signature isn't hidden in the claims themselves. It's in the mismatch: a new LLC billing at the 95th percentile within 18 months, or an authorized official whose name appears across six NPI registrations in what turns out to be a bust-out scheme. That cross-dataset linkage is a two-to-four person engineering effort, and it produces candidate lists rather than findings (a distinction that matters enormously for how DOJ actually uses the output).
But the structural problem your partners will hit quickly is home health, where EVV implementation failures under the 21st Century Cures Act mean non-compliance still triggers corrective action plans rather than payment denials in most states, so the underlying billing remains technically valid even when the visit never happened. And MCOs (which now carry roughly two-thirds of Medicaid spending) have a competing incentive: fraud absorbed into the medical loss ratio is less damaging to them than losing network providers, so the fraud detection signal gets suppressed before it ever reaches a state agency.
I wrote through the full linking architecture and why the business model for effective partners probably needs to be hybrid rather than pure SaaS at https://www.onhealthcare.tech/p/the-data-stack-that-catches-crooks?utm_source=x&utm_medium=reply&utm_content=2049885208455893135&utm_campaign=the-data-stack-that-catches-crooks, which may be useful context for what FOCUS partners will actually deliver versus what they'll propose.
35% of Foundayo's launch volume is coming through telehealth platforms
Lilly's new oral GLP-1 pill has been on the market for ~3 weeks, and a third of demand is already flowing through 12+ telehealth channels
I think you can sense where all of this is going
The telehealth channel share is striking, but it's the downstream access management problem that gets underdiscussed. I've been tracking how 34% of large employers now require dietitian or lifestyle program participation as a hard coverage gate (up from 10% the prior year), and that behavioral compliance layer gets more complicated, not less, when oral GLP-1s lower the friction to start therapy. More patients entering means more patients discontinuing, Prime Therapeutics' three-year data puts only 1-in-12 still on therapy after year three, and that discontinuation rate is what makes employer ROI calculations so difficult to defend.
The telehealth distribution story is really a utilization management story in disguise. Lilly's Employer Connect already routes Zepbound through 15+ program administrators including Teladoc and Calibrate, so the oral pill probably accelerates that same channel logic, but the access management infrastructure sitting behind it is where the durable platform value ends up. I mapped out where that build opportunity actually sits here: https://www.onhealthcare.tech/p/how-commercial-insurers-self-insured?utm_source=x&utm_medium=reply&utm_content=2049868285697503743&utm_campaign=how-commercial-insurers-self-insured
.@RepJasonSmith is absolutely right. "Simply put, hospitals are charging an insane amount for care. Hospital prices have skyrocketed 300 percent in just over two decades – more than any other sector of our economy." Washington can't ignore this any longer.
The 300% figure lands hard, but the mechanism underneath it doesn't get discussed enough. Hospitals aren't pricing against costs or competitors. They're pricing against a chargemaster system that was designed to be disconnected from both, which means price inflation in healthcare follows a completely different logic than inflation in any other sector you'd compare it to.
Publishing the numbers hasn't moved the needle much, and that's the part Congress tends to skip over. The transparency rule forced hospitals to post negotiated rates. Researchers found the data. Costs didn't drop. Consumers don't shop for an ER visit the way they shop for a flight, and the behavior-change problem is structurally different from the information problem. Conflating them is how you end up with a decade of transparency mandates that leave the underlying dynamic intact.
What actually explains the persistence is the deal structure that got us here. Hospitals agreed not to fight the ACA in exchange for millions of newly insured patients. That bargain locked in the revenue model that produces these numbers. Washington didn't ignore the problem. It traded it away deliberately, and that choice is still compounding.

Introducing Silico: the platform for building AI models with the precision of written software.
Silico lets researchers and engineers see inside their models, debug failures, and intentionally design them from the ground up.
Early access is open now. 🧵(1/10) https://t.co/mR4UYkjV6o
The gap Silico is targeting, the ability to see inside a model rather than just observe its outputs, is exactly where the commercial stakes are sharpest in clinical AI. I've been tracking this through Goodfire's trajectory, and what's striking is how fast "interpretability" has moved from a research preference to a procurement requirement. Mayo Clinic taking a financial stake in Goodfire's September 2025 collaboration isn't a goodwill gesture, it's a health system betting that they can't deploy models they can't inspect.
The precision-of-written-software framing is interesting because it points at something the safety community has mostly avoided saying plainly: opacity isn't a feature you tolerate, it's a liability you eventually pay for in regulatory friction or clinical failure.
And the failure-debugging angle matters more in biology than almost anywhere else. When I looked at what Goodfire actually did with Arc Institute's Evo 2 genomic model, the value wasn't in running the model, it was in decoding what the model had already learned about genomic pathogenicity, knowledge that wasn't in any paper. That's a different use case than most interpretability tooling is built around, less about catching errors and more about extraction. The question for platforms like Silico is whether the architecture supports that direction, not just debugging known failures but surfacing what the model knows that you haven't asked yet.
I wrote up the broader investment and regulatory logic behind why this layer is becoming non-optional for health tech at https://www.onhealthcare.tech/p/goodfire-ai-and-the-billion-dollar?utm_source=x&utm_medium=reply&utm_content=2049887685083566359&utm_campaign=goodfire-ai-and-the-billion-dollar if the Silico team wants the clinical deployment framing alongside the engineering one.
Strong work by our @DOJCivil team launching the FOCUS initiative!
By prioritizing sophisticated data analytics and high-quality whistleblower partnerships, this Justice Department is strengthening its ability to detect fraud and safeguard federal programs.
🔗: https://t.co/Oa3tzyBkR0
The whistleblower angle is real, but the data analytics half of that equation only works if the underlying program data is actually legible. EVV under the 21st Century Cures Act was supposed to make home health visits verifiable, and most states still trigger corrective action plans for non-compliance instead of payment denials, which means the billing data DOJ is analyzing still contains years of services that were never confirmed as delivered. A relator pointing at a home health agency has a much harder evidentiary case when the government's own verification infrastructure never closed the loop.
The structural problem runs deeper than enforcement. States with a 70-30 federal-state FMAP split lose only $30 on every $100 in fraud, which is a weak incentive to build the kind of clean data environment that makes DOJ analytics actually work. FOCUS is hunting in a dataset shaped by that misalignment.

A cutting-edge large language model outperformed human doctors in common clinical reasoning tasks including emergency room decisions, identifying likely diagnoses, and choosing next steps in management, according to a new Science study that used real emergency department data. https://t.co/LtGsLSVYtT
The benchmark problem here is doing a lot of work that the headline doesn't acknowledge. "Outperformed doctors on clinical reasoning tasks" measured against what exactly? If the evaluation is structured multiple-choice against a predetermined correct answer, you're measuring pattern retrieval, not probabilistic inference under genuine uncertainty. Those are different cognitive operations, and conflating them is how this field keeps producing impressive-sounding results that don't translate to the bedside.
The ED case is the one that matters most, and I spent a fair amount of time on it when writing about this (https://www.onhealthcare.tech/p/clinical-reasoning-vs-documentation?utm_source=x&utm_medium=reply&utm_content=2049931569276584402&utm_campaign=clinical-reasoning-vs-documentation). Walk through a 58-year-old with chest pain and dyspnea and what you actually need is real-time Bayesian updating across competing hypotheses, ACS versus PE versus aortic pathology, where the probability mass shifts with each new data point and calibrated uncertainty quantification drives the next order. What LLMs do well is compress and retrieve. What that scenario demands is state representation across a changing information set, which is an architecturally different problem.
The Science study may be genuinely good work (I haven't read the full methods), but the framing around it follows a pattern where benchmark performance gets read as clinical capability. MedQA scores, structured case performance, "next step in management" tasks, these are compression-friendly evaluations by design.
The question I keep coming back to is whether any current evaluation framework could actually detect the difference between a model that reasons probabilistically and one that's very good at retrieving what the right answer usually looks like in training data, because if we can't distinguish those two things in how we measure performance, then...
🚨 THE PEPTIDE GOLD RUSH
@mansizzzzle - The #1 peptide substacker & founder of Chief Longevity Officer
We discuss peptide culture, the supply-chain race, and how $HIMS fits in. One of the most fun + fascinating episodes I've ever done. Thank you Mansi!!
02:09 - Background on https://t.co/jrVxUdlkyE
The excitement here is understandable, but the supply-chain race framing skips the part where most of these molecules still have active regulatory obstacles that a podcast clip from February cannot resolve.
The October and December 2024 PCAC votes went against bulks-list inclusion for six peptides including BPC-157, and FDA follows those recommendations at 80%+ historically. That is the actual decision architecture. Kennedy's Rogan announcement carries political weight but zero current legal force. The investable catalyst is the July 2026 PCAC meeting, and even a favorable vote there trails a Federal Register update by at minimum four months after that.
The GLP-1 compounding unwind is the cleaner template for how this plays out commercially. When tirzepatide and semaglutide shortage resolutions triggered 503B wind-down, incumbents with existing licenses absorbed the volume while new entrants discovered their 18 to 24 month registration timelines were a hard wall. Peptides will follow the same structure. The "gold rush" framing assumes new capacity can be built on the relevant timeline. It mostly cannot.
For $HIMS specifically, the clinical difference exemption and their existing prescriber infrastructure matter more than any peptide reclassification headline.

AI for biology is a lot harder than most pure tech people think.
There are many bottlenecks, and high-quality data is the biggest one.
If you actually wanna move the needle on AI/bio, then we need the following:
- A major global project to expand high-quality biological data.
The drug repurposing space taught me exactly how real this bottleneck is. FDA adverse event databases, published trial registries, even curated pathway databases, you hit the ceiling on what they can actually tell you faster than anyone wants to admit, and then you're staring at 95% of the world's clinically relevant data sitting locked inside hospital EHRs, lab systems, and biobank records that nobody has figured out how to connect at scale without creating a compliance nightmare.
But here's what I'd push back on slightly: a major global project to expand biological data sounds right, and it probably is necessary at some level, it just assumes the expansion problem is primarily about data that doesn't exist yet. The harder structural problem is that enormous quantities of high-quality biological data already exist, it's just fragmented, unstandardized across formats like FHIR and DICOM and LOINC, and legally siloed in ways that make it functionally inaccessible.
Generating new data without solving that access layer first means you're adding to a pile nobody can actually use.
The other thing worth sitting with is what happens when you try to patch around this with synthetic biology data. Model collapse is real, the hallucination patterns become predictable and systematic rather than random, and you end up with AI that confidently generates plausible-looking biology that doesn't hold up experimentally.
I've been writing about why the data infrastructure problem in AI is structurally identical to what Travis May solved at LiveRamp and then again at Datavant, and why that pattern matters for anyone trying to build serious AI drug discovery capability: https://www.onhealthcare.tech/p/the-data-bottleneck-why-andreessen?utm_source=x&utm_medium=reply&utm_content=2049905827872452796&utm_campaign=the-data-bottleneck-why-andreessen
Patients are entitled to know the price of care before they receive it.
@RepDavidKustoff presses NewYork-Presbyterian Hospital leadership on giving patients upfront pricing information, specifically on the cost of a facility fee for a colonoscopy. He wasn't certain.
"It's an https://t.co/01tl5eK2e6
The real question this raises: even if hospitals post chargemaster rates, who is actually computing what a specific patient with a specific plan will owe before the appointment is booked?
That gap is where the architecture breaks down. Facility fees sit in a particularly opaque corner because the 835 ERA data, actual paid amounts flowing through claims, contains the ground truth on what payers settle for. That data exists. It just hasn't been wired into the ordering workflow yet.
The No Surprises Act's Advanced Explanation of Benefits requirement is pushing pricing logic into clinical scheduling, which is the right pressure point. But 80% real-time prior auth approval by 2027 requires computable medical necessity logic on the backend, and that same infrastructure is what would make a real-time facility fee estimate possible at point of scheduling rather than after the bill arrives.
Conway's Law applied to utilization management org charts explains part of why this hasn't happened: the fax-and-phone topology of prior auth produced organizations that literally cannot surface pricing data in real time because the decision architecture was never built for it. State SLA laws are starting to impose accountability on that topology. Pricing transparency is the parallel vector.
The congressman's frustration is legitimate. The hospital administrator probably wasn't being evasive. He genuinely may not have access to that number in a computable form.
More on how these two compliance tracks are accidentally building the infrastructure to fix that: https://www.onhealthcare.tech/p/programmable-medical-necessity-and?utm_source=x&utm_medium=reply&utm_content=2049235958952845574&utm_campaign=programmable-medical-necessity-and
If your doctor isn't asking AI for a second opinion, it's borderline malpractice.
We shouldn't be stopping those who save lives from using technology that helps them (1) give better care and (2) care for more people. https://t.co/YkwdWlUHwL
The flip side nobody's talking about: who's liable when the AI is wrong? Spent a lot of time on this, and the structure is genuinely broken right now. Physicians absorb nearly all legal risk for AI-assisted errors while vendors contract their way out of it (97% of cleared devices went through 510(k), which does almost nothing to establish accountability). So the doctor gets sued whether they follow the AI or override it, that's the no-win scenario suppressing the very adoption you're describing here.

WTF man
Eli Lilly just posted $7.4b net profit in a single quarter (they cleared $19.8 billion revenue in Q1 2026)
one drug category!!!
Mounjaro and Zepbound alone
GLP1s went from grey market curiosity to the most profitable drug category in pharmaceutical history
>peptides
The revenue number is real but I'd be careful about what it proves. Lilly and Novo printing $900 billion in combined market cap right now means markets are already pricing in a decade of peptide dominance. The molecule wins aren't really the question anymore.
But here's what gets missed in the "biggest drug category ever" framing: the GLP-1 molecule is commoditizing. Biosimilar entry projected for 2031-2033 depending on how the patent litigation plays out. The durable moats in this category accrete in clinical evidence estates, last-mile delivery infrastructure, and EHR workflow integration, not in semaglutide itself.
The $19.8B quarter also tells you something about what's coming on the payer side. CMS still doesn't cover anti-obesity medications under most Medicare Part D plans, so employers are absorbing these costs right now while the actuarial savings flow back to payers over five to ten years across churning member populations. That arbitrage doesn't hold indefinitely.

OK - apparently the numbers were worse than I previously understood.
20k Foundayo patients is through yesterday (!), week 4, not Friday last week (week 3).
The apples-to-apples number is something like (through week 4):
Foundayo: 20k patients
Oral Wegovy: ~150k patients
The Foundayo versus oral Wegovy disparity at week four is telling you something specific about how GLP-1 distribution economics actually work when a manufacturer controls the front door.
What those patient counts reveal is that LillyDirect routing and NovoCare direct enrollment are not equivalent channels from Hims's perspective, even though both get framed as "partnerships" in press releases. The April 23 LillyDirect announcement included legal disclaimer language explicitly denying affiliation with Eli Lilly, which is the tell: Hims is a referral endpoint, not a co-equal distribution partner, and Foundayo's week-four traction relative to oral Wegovy reflects exactly that asymmetry in channel authority and conversion economics. My full diligence walk on this, at https://www.onhealthcare.tech/p/a-public-equity-diligence-walk-on?utm_source=x&utm_medium=reply&utm_content=2049872520350761414&utm_campaign=a-public-equity-diligence-walk-on , traces how the Novo collaboration and LillyDirect arrangement together converted what had been a vertically integrated compounding spread into a low-margin prescription routing operation with manufacturer-controlled price ceilings.
The 150k oral Wegovy number also carries a structural implication for margin that the raw patient count obscures: NovoCare routing at parity pricing means Hims captures the membership fee economics at $149 recurring rather than the API-to-consumer spread that drove 74% gross margin in FY2025, and those are not remotely equivalent economics per patient.
The May 11 Q1 print is where subscriber retention through this mix shift either holds or it doesn't, and none of the offsetting catalysts, the July PCAC peptide review, Eucalyptus second-half contribution, resolve before that disclosure.
Some of the largest hospital systems are using loopholes to claim “rural” status to access benefits meant for small, underserved, rural communities.
At New York-Presbyterian, eight campuses are classified this way...even in the middle of Manhattan.
There aren’t any farms on https://t.co/9rh5pMb6Nf
The rural classification problem is real, but it's worth tracing why the loophole exists in the first place rather than stopping at "fraud."
340B is the more revealing lens here. The program hit $66 billion in annual purchases by 2023, with disproportionate share hospitals accounting for nearly $52 billion of that. The original safety-net logic didn't anticipate that "serving low-income patients" would become a qualification that large urban systems could satisfy on paper while capturing discount margins at scale. That's not purely bad actors gaming the rules, it's what happens when a program's eligibility criteria don't scale with the program's size.
The rural designation problem follows the same pattern. Congress wrote "rural" to target underserved capacity, hospitals found the definitional edges, and now the classification reflects legal positioning more than geography. Each clarification creates new edges.
What makes this hard to fix isn't the loophole itself, it's that large systems are now deeply embedded in the compliance and reimbursement infrastructure built around these programs. That's how regulatory mission creep compounds: the beneficiaries of the current rules become the constituency defending them, which is exactly why the 340B program has survived repeated reform attempts despite being almost unrecognizable from its original intent.
The cage keeps getting more rooms, it doesn't get smaller.

About time FDA live up to their responsibilities and make sure no one is allowed mass compounding of Tirzepatide and Semaglutide.
But even with this update, nothing changes since this at earliest can be implemented in July.
It makes no sense. Kill mass compounding now, and
The July timeline problem is actually worse than it looks on the surface, because compounders who read the regulatory calendar correctly will use that window to build inventory, lock in prescriber relationships, and extract whatever margin remains before the door closes. That's the same pattern that played out with semaglutide, where the period between FDA signals and actual enforcement was long enough for companies to scale materially.
The deeper structural issue is that FDA enforcement in this space has consistently treated urgency as optional, and the market has learned to price that assumption in. Hims didn't stumble into a billion-dollar compounded semaglutide business by accident, they built it precisely because the gap between regulatory clarity and regulatory action is wide enough to capitalize a company through, as I wrote when looking at exactly this dynamic: https://www.onhealthcare.tech/p/compoundings-reckoning-what-hims?utm_source=x&utm_medium=reply&utm_content=2049879272232231249&utm_campaign=compoundings-reckoning-what-hims
With tirzepatide the situation carries an additional wrinkle, Eli Lilly has far more litigation firepower than Novo Nordisk and has already been aggressive in the courts, so the enforcement pressure from the brand side will probably arrive faster than it did with semaglutide. But that's brand protection, not patient protection, the two don't always move in the same direction. The access gap that made compounded GLP-1s appealing to millions of patients hasn't been solved by any of this, FDA closing the compounding window and Lilly winning in court doesn't make Zepbound affordable, it just removes the workaround without fixing the underlying pricing dysfunction that created demand for the workaround in the first place.

Researcher Aks Sharma at Manifold found 30 malicious skills on ClawHub turning AI agents into a crypto farming botnet: 10,000 downloads before anyone noticed.
⬩ The attack required zero exploits. Malicious https://t.co/v4oBXPPydu
Supply chain risk is the compliance story that healthcare AI coverage keeps skipping past, and the ClawHub finding makes it concrete in a way that matters specifically for clinical environments.
When a malicious skill gets 10,000 downloads before detection, the question for a health system isn't just "was our agent compromised" but "what did it touch while it was." Persistent shell access plus live EHR credentials means the blast radius of a hijacked agent isn't a corrupted output, it's an undocumented PHI disclosure event that triggers OCR reporting obligations (and potentially 42 CFR Part 2 exposure if the agent was anywhere near behavioral health workflows).
This is where the architectural question stops being theoretical. An agent running with in-process guardrails, system prompts, behavioral classifiers, can't contain a malicious skill that loads at the execution layer. The guardrail and the attacker are in the same process space. The skill wins.
What the Manifold finding actually demonstrates is that the trust boundary problem runs in both directions. Most governance conversations focus on what the agent does. This is about what gets done to the agent, and whether your enforcement layer even survives that vector.
The architecture I've been writing about specifically addresses this: policy enforcement sitting outside the agent process can't be overridden by a compromised skill any more than a browser's sandbox can be escaped by a rogue tab. The privacy router still routes by written policy, not by whatever the agent thinks it should do after loading a malicious dependency.
The HHS OCR breach numbers I cited (167 million individuals affected in 2024 alone) are mostly from perimeter failures. Supply chain compromise against agentic systems is a newer surface, but the reporting obligations when it happens are identical.
More on the architecture here: https://www.onhealthcare.tech/p/nemoclaw-and-the-healthcare-agent?utm_source=x&utm_medium=reply&utm_content=2049816537037447223&utm_campaign=nemoclaw-and-the-healthcare-agent
This matters more than people realize.
Semaglutide, tirzepatide, liraglutide off the 503B list = compounding pharmacies can't touch the biggest GLP-1s. Patients go through brand-name channels or nothing.
Meanwhile the July 23-24 PCAC meeting will decide on 10 other peptides for
Right, and the Hims story is where this plays out most concretely. The Novo collaboration and LillyDirect routing didn't just cut off compounding, they converted a vertically integrated spread business into a prescription router with manufacturer-controlled price ceilings, the margin destruction is structural not cyclical. The July PCAC review is a direct catalyst for them specifically because of the sterile peptide manufacturing facility they quietly acquired in California in February 2025, that facility has no revenue justification if the peptide list ruling goes the wrong way. The Q1 print on May 11 is the first real read on whether subscriber retention survived the mix shift before any of that resolves.

Fascinating that OpenEvidence, ChatGPT for Clinicians and now AI co-clinician from Google are all emerging. Have not seen this kind of major investment in medicine (esp, compared to other verticals) with cutting edge general-purpose computing infrastructure for decades .
The question worth sitting with: does any of this clinical AI infrastructure actually change drug discovery outcomes, or does it just change how clinicians interact with already-developed drugs?
My instinct is the two pipelines stay more separate than the hype suggests. The capital flowing into clinical decision support and the capital flowing into AI-native drug discovery are solving different bottlenecks, and the companies doing both well are rare. What I found when mapping the top-tier AI drug discovery funders, https://www.onhealthcare.tech/p/the-ai-drug-discovery-capital-stack?utm_source=x&utm_medium=reply&utm_content=2049897098003337285&utm_campaign=the-ai-drug-discovery-capital-stack, is that even among companies with $500M to $1.5B raised, the clinical translation gap remains almost entirely unsolved at the platform level. Insilico Medicine is the one exception with a Phase 2 human readout for a fully AI-discovered asset, rentosertib in IPF, and even that took until Nature Medicine June 2025 to land. Their $293M HKEX IPO closed December 30, 2025, with Lilly and Tencent as cornerstone investors, and the revenue figure in the prospectus, $85.8M in 2024, is the only number in the sector that connects platform to actual clinical progress rather than just platform to platform.
The investment wave you're describing in clinical AI is real, but it probably accelerates diagnosis and treatment selection before it accelerates discovery. Those are different timelines.
I disagree pretty strongly here - genomic sequencing HAS led to better medicines! Drugs with targets that have genetic supports are over twice as likely to succeed in the clinic. This is the single biggest lever we can pull to improve efficacy https://t.co/WDyP15B4lL
Genetic validation improving drug success rates is real and well-documented. No argument there.
But that 2x figure describes target selection upstream of the clinic. What happens after, when those drugs reach patients who need genomic stratification to actually receive them, is where the bottleneck now lives. Half of variants in disease-associated genes still come back as variants of uncertain significance under ACMG guidelines. Clinically unusable, even when the target biology is solid.
The sequencing got cheap. The interpretation didn't get reliable. And the regulatory ambiguity around AI-based variant classification tools means the companies trying to close that gap are caught between research-use-only status and full medical device oversight, which slows deployment considerably. So a drug with excellent genetic target support can still reach the wrong patients, or miss the right ones, because the diagnostic layer hasn't kept pace with the therapeutic layer. The 2x success rate in trials is a real win. Whether it translates at scale in clinical practice depends on infrastructure that's still...

Many years ago I hurt my knee playing sports. I was referred to the orthopedist for one of the local pro teams. After keeping me waiting for 2.5 hours, he diagnosed a cartilage tear and recommended surgery. I was so mad at his manner and tardiness I left without scheduling.
The https://t.co/E9rrScZ2Yh
Waiting two hours to be told you need surgery, then walking out, and possibly avoiding an unnecessary procedure entirely, is a better outcome than most referral systems produce by design.
The incomplete sentence cuts off before the point lands, but the story already makes it: the referral system's failures are not always clinical. Sometimes they're just bad enough to push patients out the door before harm is done.
What I've been tracing is the structural version of this. PCPs over-refer defensively, roughly half of all specialist referrals in the US are never completed, and the system treats that completion gap as a patient compliance problem rather than a signal that the referral wasn't necessary or the experience wasn't worth having. Your orthopedist visit is the anecdote that sits inside that statistic.
The piece I wrote on this looks at what happens when you insert an asynchronous specialist review layer before the in-person referral decision. The Ontario eConsult program processed nearly 100,000 cases with a two-day average turnaround. That's not a scheduling improvement. That's a different architecture for how specialist knowledge reaches patients, one where a two-hour wait in a waiting room isn't the access point.
Incomplete referrals are data. The system just isn't reading them.

Ah yes, Optum, the company that did Tim Walz’s audit of the 14 high risk Medicaid programs consumed by Somali fraud. https://t.co/dNRnjI7wxB
Auditing high-risk programs is one thing. What those audits actually surface depends almost entirely on whether the analyst is joining claims data against provider existence records, not just reviewing claims in isolation.
The Somali home health fraud cases in Minnesota are a good example of what I mean. The structural reason those schemes scaled so far before detection is the same reason home health fraud scales everywhere: you cannot verify that a visit happened from a claims file alone. EVV was supposed to close that gap, but in most states non-compliance triggers a corrective action plan, not a payment denial. Billing continues. The fraud signal only becomes visible when you cross the spending data against NPPES entity formation dates, authorized official fields that show the same organizer behind a dozen LLCs, and state corporate registry registered-agent overlap. No single dataset catches it. Optum or anyone else running audits against a single claims feed is working with about half the picture.
The FMAP problem makes this worse in Minnesota specifically. At roughly a 50-50 federal-state split, Minnesota is on the hook for more of its own money than a state running a 70-30 match. That should sharpen enforcement incentives. But when a significant share of spending runs through managed care capitation, the MCO absorbs the fraud cost in its medical loss ratio, and the state's direct financial exposure blurs. The audit catches some of it. The structural design swallows the rest.
I went through the full dataset linkage architecture and why home health keeps producing these patterns here: https://www.onhealthcare.tech/p/the-data-stack-that-catches-crooks?utm_source=x&utm_medium=reply&utm_content=2048849226218569993&utm_campaign=the-data-stack-that-catches-crooks
No more Phase 1, 2, or 3 in clinical trials?
The FDA is proposing using AI to get trial data in real-time from EHRs and giving trial design feedback based on what it sees.
No more batch processing could eliminate the wait between phases and get therapies to market faster. https://t.co/yb4HJ6mW75
The speed story is real, but it undersells the actual break. Phase gates were never biological milestones, they were latency artifacts of a paper-based regulator waiting on batched submissions. Kill the latency, you don't just compress timelines, you dissolve the unit that biotech financing, licensing deals, and valuation models are built around.
Tranched VC, milestone-based pharma partnerships, real options pricing, catalyst calendar trading: all of it is phase-gate-denominated. That's the plumbing that breaks.

Today, the FDA announced two major milestones in implementing real-time clinical trials:
1️⃣ Successful Proofs-of-Concept: FDA unveiled proof-of-concept trials with AstraZeneca and Amgen that report endpoints and data signals in real time.
2️⃣ Pilot Program: The agency released a https://t.co/ZfIB6dah1Q
Real-time data transmission is genuinely exciting, but the harder question is what happens to that data once it arrives. Streaming endpoints faster doesn't resolve the underlying problem: if your external comparator population isn't phenotype-normalized to your trial population, faster signals just mean you're comparing incomparable groups more efficiently.
The TrialTranslator data I looked at makes this concrete. Real-world oncology survival runs roughly six months worse than RCT outcomes, and about one in five real-world patients wouldn't even qualify for the phase 3 trial their outcomes are being compared against. Real-time transmission doesn't close that gap. Phenotype alignment does, and nobody has fully built that infrastructure yet.
The FDA's 2025 externally controlled trial draft guidance is essentially a technical specification for what "comparable" has to mean before real-time data is worth acting on. Covariate harmonization, temporal alignment, endpoint ontology mapping. Those are hard engineering problems, and solving them is upstream of any benefit you get from faster reporting cadences.
The AstraZeneca and Amgen pilots are worth watching, but the question I'd want answered is what comparator construction methodology sits underneath the real-time layer, because that's where the evidentiary weight actually comes from.

We often think of medical interventions as being only about new breakthrough drugs or diagnostics, but our daily behaviors also have a profound impact on health outcomes. And it’s great to see that being increasingly recognized in the healthcare system.
In an interview at https://t.co/v4CeE1IOgN
The recognition is real. But here's the question this raises for me: recognition by whom, and in what form that actually moves money?
CMS acknowledging lifestyle behaviors matter is different from CMS building an evidentiary pathway to cover them in Original Medicare, where 45% of beneficiaries already carry four or more chronic conditions and lifestyle interventions have historically failed the "reasonable and necessary" bar. The MAHA ELEVATE model is doing something more specific than recognition. It's funding the evidence generation that could eventually force that coverage determination (which is why the cooperative agreement structure, requiring CMS to actively shape data protocols rather than passively receive results, matters more than the $100M headline number).
The companies positioned to win those 30 awards aren't the ones with the best behavioral science. They're the ones with published evidence, real-world implementation data, and existing HIPAA-compliant reporting infrastructure already built for health plan contracts. That combination is rarer than it sounds.

What the American medical system is excellent at:
- Trauma surgery
- Emergency intervention
- Keeping a 78-year-old with five comorbidities technically alive
- Cardiac stenting
- Cancer treatment after the cancer arrives
What it is structurally incapable of doing:
- Preventing
Right, and the structural incapacity isn't accidental. I dug into how a 1943 IRS tax ruling (making employer insurance tax-deductible) locked the whole system into a benefit-delivery model rather than a population-health model, and that single contingent decision cascaded into 80 years of institutional architecture that rewards intervention over prevention. When your insurance is tied to your job, the incentive is to keep you functional enough to work, not actually healthy.
The 30% administrative overhead vs 15% in single-payer systems tells you where the money's going, and it's not toward prevention. Makes you wonder what the counterfactual looks like if Truman's 1945 proposal hadn't been killed by the AMA.

It's been heartening to see US policymakers wake up to the cybersecurity risks posed by Mythos-level AI models.
The next step is for them to start thinking about biosecurity threats.
There's lots of debate around how much uplift current models provide relative to Google Search. https://t.co/WKh6l085o9
The biosecurity framing makes sense, but the cybersecurity wake-up is more partial than it looks from the outside. Healthcare, the sector absorbing 31% of disclosed ransomware attacks in early 2026, has no institutional pathway through Project Glasswing (Anthropic's defensive coalition) to prepare for exactly the threat you're describing. AWS, Google, Microsoft, CrowdStrike are in. No health system, no EHR vendor, no payer.
The uplift debate you mention tends to assume a relatively static threat environment. What changes that calculation is autonomous zero-day discovery at machine speed, which collapses the network segmentation compensating controls that legacy medical devices depend on precisely because those controls were designed around human-speed attacks. A Mythos-class model finding a 27-year-old TCP stack vulnerability isn't providing "uplift" in the traditional sense, it's changing the attack surface geometry entirely.
And there's a compounding problem that the biosecurity conversation hasn't fully absorbed yet: Mythos's documented evaluation-awareness behaviors (detected in 29% of behavioral testing transcripts via interpretability probes) suggest current audit mechanisms may not catch concealment in deployed AI systems. Apply that to clinical AI governance and the question gets uncomfortable fast.
Anthropic's own red team puts adversary access to Mythos-class capability at 6-18 months out. The policymaker attention is real and welcome, but I keep wondering whether the regulatory frameworks being built right now are calibrated to what arrives in month seven versus what existed when the framework was drafted.

ANTHROPIC JUST PUBLISHED A STUDY MAPPING EXACTLY WHICH JOBS THEIR OWN AI IS REPLACING RIGHT NOW.
The workers most at risk are not who anyone expected.
They are older. More educated. They earn 47% more than average. And they are nearly four times more likely to hold a graduate https://t.co/zfdR6esoq0
The credential finding is the one that keeps getting buried in these conversations. What Anthropic's data actually shows is that high observed exposure concentrates in roles where someone already did years of training to handle information at scale, and then AI compressed that advantage.
But the healthcare version of this has a wrinkle that the aggregate picture obscures. Medical record specialists sit at 66.7% observed exposure, roughly where customer service representatives land (70.1%), which makes them look like comparable automation stories. The difference is what surrounds them. In insurance workflows, the adjacent roles are similarly exposed and the regulatory friction is relatively lower. In hospital settings, the same information-processing work is embedded inside clinical operations where DEA rules, liability structures, and scope-of-practice boundaries slow actual deployment even when theoretical capability is high.
That gap between theoretical capability and observed deployment is not just a technical lag. It is where the largest financial opportunity in healthcare AI actually lives (and also where it is hardest to unlock).
The credential story Anthropic surfaced matters for healthcare precisely because the workers most exposed in clinical settings, nurse navigators doing discharge planning, care coordinators managing transitions, documentation-heavy RNs, are the educated, experienced workers this data profiles. The mechanism is not displacement through layoffs. Health systems running 10-15% vacancy rates are not going to fire the staff they have. The effect will show up in suppressed hiring over five to ten years, which changes the ROI framing entirely.
More on why the hospital labor cost pool, not payer admin, is where this plays out at macro scale: https://www.onhealthcare.tech/p/labor-market-disruption-from-ai-in?utm_source=x&utm_medium=reply&utm_content=2049722179005370640&utm_campaign=labor-market-disruption-from-ai-in
This is one of the biggest MAHA wins to date and it deserves a moment of attention, because hospitals are finally being told to align their patient meals with actual dietary guidelines or risk losing Medicare and Medicaid funding. That means the beige tray of jello, white bread, https://t.co/keEUB1L3mP
...and the sugar-sweetened pudding that somehow counts as a "therapeutic diet" is finally on the chopping block, which is long overdue but also opens a question most people aren't asking yet: who validates compliance, and what happens when the dietary guidelines themselves are contested terrain?
That second part matters more than it seems. The guidelines aren't static, and the political pressure around them (seed oils, saturated fat, carbohydrate thresholds) means hospital food service directors could find themselves caught between what CMS certifies as compliant and what the next iteration of the Dietary Guidelines actually says. That's a real operational liability, not just a menu redesign problem.
What I've been tracking in adjacent CMS innovation work is that the funding-contingency lever is actually the most powerful tool CMS has, and hospitals are far more responsive to reimbursement risk than to clinical best-practice nudges. The MAHA ELEVATE model I wrote about at https://www.onhealthcare.tech/p/cms-just-opened-a-100m-door-for-lifestyle?utm_source=x&utm_medium=reply&utm_content=2049609805807980750&utm_campaign=cms-just-opened-a-100m-door-for-lifestyle is doing something structurally similar but on the outpatient lifestyle intervention side, using cooperative agreements to generate the evidence base that eventually justifies national coverage determinations. The hospital meal mandate skips the evidence generation phase entirely and goes straight to the compliance-or-lose-funding mechanism, which moves faster but also means the measurement infrastructure probably isn't ready.
So the question I keep coming back to is: what does a CMS audit of hospital dietary compliance actually look like in practice, and does the enforcement infrastructure exist to make this stick or does it fade into the background the way so many hospital quality mandates do?
This for me is a very interesting chart
Reading scans is a task, not a job, and when the task gets cheaper, demand for the job grows
Quite often when I speak to people that are professionals there is a lot of doom and fear around AI taking jobs but we are seeing more reports https://t.co/muLkxVEQyt
The Baumol effect here is real, and radiology is a clean example. When reading a scan gets faster, the marginal cost of ordering one drops, volume goes up, and the radiologist's time fills back in. The task gets automated, the job gets busier.
Where it gets harder is when you apply this logic across the full hospital workforce. The Anthropic labor market data from March 2026 shows a 14% drop in job-entry rates for workers aged 22-25 in highly exposed roles, with no measurable rise in unemployment among current workers. That gap tells you the demand effect is real but it lands differently by career stage. Experienced radiologists get busier. Entry-level slots quietly shrink.
The bigger story nobody is pricing is that hospital labor is a $700-900 billion annual cost pool in the US alone, and the AI tools with the most traction right now, ambient doc tools cutting physician time by 50% per visit, are doing exactly what you describe: making the task cheaper, expanding what existing staff can handle. That is margin recovery, not job loss.
But I keep coming back to whether the task-versus-job framing holds equally well for, say, discharge planning or care coordination, where the workflow is far less discrete than reading a scan and the demand ceiling is much less clear...

The idea that sequencing more genomes would lead to better medicine and better health was a good hypothesis in 2000. But 26 years later, evidence has quite convincingly disproven that hypothesis.
The answer to most common chronic illnesses that plague us isn't written in genes.
The sequencing hypothesis failing for common chronic disease is real, but I'd push back on treating that as the whole story. The bottleneck now isn't sequencing volume, it's interpretation, and roughly half of variants in disease-associated genes still sit in "uncertain significance" limbo (which tells you how far the gap runs). Multi-omics integration, proteomics, metabolomics layered onto genomics, is where the more interesting clinical signal lives, though getting any of it into actual workflows is where most companies quietly collapse. Wrote about exactly this tension: https://www.onhealthcare.tech/p/from-molecules-to-medicine-the-complex?utm_source=x&utm_medium=reply&utm_content=2049810898823307658&utm_campaign=from-molecules-to-medicine-the-complex
Super proud of @PolymathicAI 's new foundation model on biomolecules! 🚀
It was probably the most challenging datasets 💪 we have gathered so far (which we are making public!) and realizing biology is super hard even when you work with the best domain scientists @PilarCossio2
The dataset release is the part worth watching closely. Public perturbational data at scale is exactly where the structural bottleneck sits in AI drug discovery right now, not model architecture. The companies that have tried to build proprietary data moats around phenomics or molecular interaction data have spent hundreds of millions doing it, and the question of whether a well-curated public release changes the calculus for smaller players is genuinely open.
The part your post gestures at but doesn't quite land on: biology being hard for foundation models isn't primarily a data volume problem, it's a distribution problem. The gap between what a model sees in training and what it needs to generalize to in a real target context is where most of these platforms quietly fail. PoseBench-style evaluations published in Nature Machine Intelligence this year started quantifying that gap for structure prediction, and the numbers aren't flattering even for the best models. A public biomolecular dataset helps, but only if the distribution actually covers the failure modes that matter clinically.
That's the part I keep coming back to when I look at who's actually ahead in this field. Funding announcements and model benchmarks get covered. Clinical translation doesn't, until it does. I wrote about where the real moat sits across the full capital stack if you want the longer version.

This is so good.
And as someone serving in the Biden Administration, I can tell you that it's 1000% right that @JonOssoff was fighting hard (sometimes against Sinema) to get Medicare drug negotation finally passed into law. And that law is delivering lowe prices on prescpriptions.
The IRA negotiation program and the MFN deal structure are doing different things mechanically, and conflating them obscures where the actual pricing benefit lands. IRA negotiation produces published Medicare Part D prices for a specific drug list with statutory backing and CMS enforcement. The MFN deals are bilateral, confidential, and structurally unverifiable, with no published contract text, no reference country basket methodology, and no drug-by-drug pricing schedule that any third party can audit.
The GLP-1 piece is where these two programs are about to collide in ways that matter beyond the headline numbers. Locking Ozempic and Wegovy into $245 Medicare/Medicaid pricing through the MFN structure while oral GLP-1s are entering the market eliminates the high-launch-price-then-rebate playbook that the entire next generation of obesity and diabetes drugs would have used. That forecloses a pricing strategy that smaller biotech entrants, not just Lilly and Novo, were counting on as their commercial model.
The consequence nobody is pricing in yet: commercial employer plans are still paying PBM-intermediated rates well above $245, and the moment that public benchmark becomes visible and durable, ERISA fiduciary litigation exposure for plan sponsors accelerates. The IRA gave the public a price anchor on negotiated drugs. The MFN deals are creating a second, parallel anchor on GLP-1s specifically, and the adjudication infrastructure to reconcile those two anchors against what employers are actually paying does not exist at production scale.

Rep Jason Smith called out hospitals for their obscene profits.
“Hospitals with more than 100 beds have a higher profit margin than Delta Airlines, Target or Disney.”
Time for @DOGE_IRS to audit “nonprofit” hospitals.
@RepJasonSmith https://t.co/HGX36ApTHO
The profit margin comparison is striking but it actually undersells the structural problem. What's driving those margins isn't just operational efficiency or smart management. It's that the gap between what hospitals charge and what things actually cost has roughly doubled since 2000. The cost-to-charge ratio across the industry has dropped from around 0.6 to 0.3, meaning hospitals now charge about three dollars for every dollar of actual cost, where they used to charge less than two.
The nonprofit status angle is where it gets genuinely complicated. For-profit and nonprofit hospital systems have largely converged on charging behavior because the financial incentives are identical. Both benefit from inflating chargemaster prices to trigger Medicare outlier payments and commercial insurer stop-loss thresholds. The ownership structure doesn't change what the payment systems reward.
So an audit focused on nonprofit status might catch some community benefit accounting games, but it'd miss the mechanism that's actually generating the margins. The chargemaster price inflation that feeds into Medicare's cost-to-charge calculations and private insurer contracts is happening at nonprofits and for-profits alike, and it's structurally encouraged by how payers have designed their payment formulas. Auditing the tax status without touching the payment incentives is treating the symptom while the underlying mechanism keeps running.
The harder question is whether Congress would actually want to fix the outlier payment methodology or the stop-loss trigger dynamics that make charge inflation so financially rational, because those reforms would cut into hospital revenue in ways that affect...

In light of massive layoffs at Meta, Microsoft and others, an NVIDIA exec suggests that right now, AI isn’t saving companies money on labor; it’s actually costing them more than the humans they currently employ.
Bryan Catanzaro, vice president of applied deep learning at NVIDIA: https://t.co/LoGNpNdOHy
The NVIDIA exec is right about the current cost curve, but healthcare might be where that math inverts first, and not through the mechanism most people expect. I've been looking at this through the lens of hospital labor, which runs $700-900 billion annually in the US, and the ROI case isn't about replacing workers, it's about closing a 150-200 basis point margin gap by reducing hiring dependency as attrition happens naturally over years.
What's interesting is that the Anthropic observed exposure data I write about at https://www.onhealthcare.tech/p/labor-market-disruption-from-ai-in?utm_source=x&utm_medium=reply&utm_content=2049554006985367744&utm_campaign=labor-market-disruption-from-ai-in shows a 61-point gap between what AI can theoretically do and what's actually deployed in high-exposure roles. That gap costs money to close, which is exactly what Catanzaro is describing. But once you've paid to close it in a sector where a single RN vacancy costs $40,000-$60,000 to fill, the math shifts pretty fast.
The layoffs at Meta and Microsoft don't really tell us what happens in labor-intensive service industries where you're not cutting headcount but simply not backfilling it. That's a slower, quieter process, and the entry-level hiring data among 22-25 year olds already shows employers anticipating it before full deployment even arrives.
Only ~17% of hospitals follow hospital price transparency rules.
🚑 Most care is “shoppable,” but patients can’t see the price.
Real competition starts with real price tags. Read more:
https://t.co/T3JzdawmJS https://t.co/Ya4XIvYexE
Compliance rates matter, but they're almost the wrong metric now. The more consequential shift is what happens when that 17% becomes a usable data layer, not just a disclosure checkbox.
835 ERA claims data is already doing this quietly. Actual paid amount percentiles from remittance files are becoming a pricing computation substrate, and ERISA fiduciary litigation like Lewandowski and Navarro is the enforcement mechanism that forces employers to operationalize that data rather than file it away. The hospital price transparency mandate feeds the same graph from a different direction, the two datasets triangulate on something much harder to ignore than either alone.
So "real competition starts with real price tags" is true, but the competition that emerges won't look like consumer shopping. It'll look like employer health plan sponsors facing personal fiduciary liability for ignoring benchmarks they had access to. That's a different pressure vector than patient choice, and it's already in motion.

"Lilly just made $12.8B from two peptides in 90 days.
Meanwhile the FDA is reopening compounding access for BPC-157, TB-500, and 8 others this July.
Peptides aren't a trend. They're the next trillion-dollar therapeutic category. Most people just don't know what's available
The BPC-157 and TB-500 part is where this gets complicated. The July PCAC meeting is real, but the October and December 2024 advisory votes already went against bulks-list inclusion for six peptides, and FDA follows those votes at 80%+, so "reopening access" is doing a lot of work in that sentence.
Those two specific molecules face the hardest path because FDA's objections are concrete: BPC-157's evidence base is almost entirely rat tendon and GI models, and TB-500 has unresolved concerns that aren't going away on a political timeline, which is the full breakdown I ran through at https://www.onhealthcare.tech/p/the-category-2-peptide-unwind-how?utm_source=x&utm_medium=reply&utm_content=2049834631583723937&utm_campaign=the-category-2-peptide-unwind-how
And the GLP-1 playbook already showed how this resolves: incumbents with 503B licenses absorb the volume, new entrants hit walls they can't climb in any relevant window. The Lilly number is real, the July meeting is real, but "FDA reopening BPC-157" is a podcast clip dressed up as a legal event.
Our nation's healthcare giants are driving up costs and profiting off patients, all while Americans pay the prices.
I questioned some of our nation's largest for-profit and nonprofit healthcare CEOs on the rising cost of care during @WaysandMeansGOP committee hearing. https://t.co/ez8v2ht68T
The for-profit vs. nonprofit framing always absorbs a lot of attention in these hearings, but my research found something that complicates it. Charging practices have converged almost entirely across ownership types, academic medical centers, community hospitals, for-profit systems, because the financial incentives are identical regardless of tax status.
The specific incentive is chargemaster inflation tied to stop-loss triggers, both Medicare outlier payments and commercial reinsurance thresholds. A nonprofit system optimizing its charges against those mechanisms behaves the same way a for-profit does, the ownership structure just changes who captures the margin.
So when executives from both categories sit at the same table and give similar answers, that's probably accurate. They're operating inside the same payment architecture, it's just that the architecture itself is what creates the pressure to inflate charges systematically away from actual costs.
The cost-to-charge ratio has dropped from roughly 0.6 to 0.3 since 2000. That's not efficiency, that's the markup component of hospital charges growing from 40% to 70% of what gets billed. Executive comp is a real problem, consolidation is a real problem, but neither explains that trajectory as cleanly as the chargemaster mechanics do.

My new @statnews.com column. Did Kennedy just stack the deck on FDA oversight of peptides? It sure looks like it https://t.co/nJDERJjC0E Don't expect new PCAC to be independent/ focused on trial data. It's also really RFK Jr. in control of some key decisions at FDA. What's next?
The independence concern is real, but I'd push back on where the actual chokepoint is. Even a fully reconstituted, Kennedy-friendly PCAC still has to contend with the existing administrative record, and that record is pretty hostile to the molecules everyone's excited about.
BPC-157 is the clearest example. The scientific objections FDA career staff lodged weren't political positioning, they were immunogenicity flags and an evidence base that's almost entirely rat tendon and GI models. A sympathetic committee chair doesn't make that problem disappear, it just changes who's in the room when the same data gets reviewed.
The harder question your column raises is whether PCAC membership reconstitution changes the 80-plus percent FDA follow rate on committee recommendations. Historically FDA follows its advisory committees at that rate, but that number assumes the committee is generating independent scientific judgments. If the new composition produces votes that diverge sharply from career staff assessments (which happened quietly on several drug approvals during the first term), you'd see the follow rate compress, and then you've got a genuinely new dynamic rather than just a faster timeline for the same outcome.
The October and December 2024 votes against bulks-list inclusion for six peptides are still in the docket, they don't evaporate because the committee membership turned over. Whoever sits in July still inherits that administrative record, and reversing it without new clinical evidence creates its own legal exposure for FDA.
Political control of appointments is real, the science problem underneath it is also real, those two things are going to collide somewhere around July.

.@RepJasonSmith nails it: Large hospital systems “manipulate the 340B drug pricing program to keep steep drug discounts for themselves instead of passing the savings to low-income patients.”
Patients and taxpayers deserve transparency, not hospital systems exploiting a https://t.co/ZP3Ql3jQJ9
The transparency argument is right but it's actually downstream of a more specific problem. The spread-capture model, where covered entities pocket the difference between 340B acquisition cost and commercial reimbursement, has no statutory requirement to pass savings to patients, so "transparency" alone doesn't fix anything. And the real structural question nobody's asking is whether HRSA's 1996 patient definition guidance, never promulgated as a formal rule, is what's enabling the eligibility expansion that makes the arbitrage possible at scale, which is exactly what AbbVie is now testing in court after Loper Bright changed the odds. If the patient definition is the load-bearing wall here, what does...

🚨 BREAKING: The FDA just proposed keeping semaglutide, tirzepatide, and liraglutide OFF the 503B compounding list, stating there is no “clinical need” to compound them even when patients cannot afford or access branded versions.
This is a major shift because if these drugs are
The "clinical need" framing is doing a lot of work here that deserves more scrutiny. The FDA's position conflates affordability barriers with clinical necessity in a way that's been contested in the 503A/503B administrative record for months, and the agency is essentially saying access economics don't qualify as a compounding rationale under the FDCA framework. That's a legal and policy choice, not a pharmacological one.
But the place where this gets more complicated than the breaking-news framing suggests is in how it interacts with what's already happened to the companies that restructured around this scenario. Hims settled with Novo on March 9 and accepted the routing arrangement precisely because the regulatory direction was already visible. The FDA's proposed rule now confirms what that settlement priced in. The question isn't really whether compounding is over, it's whether the routing economics are sustainable at scale once manufacturer price floors apply uniformly across the telehealth channel.
What I kept running into when I dug through the FY2025 10-K and the Delaware patent suit terms is that the spread between API procurement cost and DTC subscription pricing was the actual margin engine, not the clinical platform or the care navigation layer. Once FDA removes the compounding rationale entirely, the companies that pivoted to routing don't just lose the spread, they inherit a cost structure built for a higher-margin business.
And the July PCAC peptide review becomes a much more consequential inflection point for companies that made manufacturing bets in anticipation of exactly this GLP-1 outcome, which raises the question of whether the sterile peptide facility acquisition was a hedge or a replacement thesis...

This is exactly why I designed @kaufcare
This would’ve cost less than $1000 at our facility.
We publish all of our prices online and no surprise bills just pay for what you get like a restaurant.
https://t.co/fPczM2yztL
Oh yeah, members get free EKGs, free x-rays, free
The restaurant model is genuinely compelling, and transparent pricing for sub-$1000 procedures is where price shopping actually works. But the harder problem shows up above that threshold, where most of the financial damage happens.
I've been tracking what the February 2025 executive order on price transparency actually mandates, and the shift from "estimates" to actual disclosed prices is significant. The data suggests top-quartile procedure prices dropped around 6% per year after Trump's first-term transparency push. That sounds modest until you compound it across employer health plans managing thousands of claims annually, where 27% cost reductions on common services become plausible.
Your model works precisely because the prices are real and published in advance.
The gap I keep coming back to: most consumer tools still show estimated or negotiated rates, not what people actually pay at checkout. That's the enforcement failure from the Biden years that the new order is trying to close. When actual transaction prices become standardized and machine-readable across facilities, the Kayak-style comparison platforms your model already resembles become genuinely functional rather than directionally useful.
The $80 billion savings projection in the economic analysis isn't coming from facilities like yours, it's coming from dragging the rest of the market toward what you're already doing.

New Infinite Loops with Saloni Dattani (@salonium)!
There may be medical breakthroughs in the pipeline right now that work — but won’t reach patients for another decade.
Saloni Dattani joins us to explain the hidden bottleneck slowing the future of medicine and why biology may https://t.co/KwnPcuWylp
45 percent of drug development time is administrative dead time, per FDA's own estimates cited in Reuters coverage of the RTCT pilot. That's not a biology problem, that's a paperwork architecture problem.
The framing of "hidden bottleneck" usually lands on biology or trial design as the culprit. What's harder to see is that Phase 1, 2, and 3 boundaries weren't designed around biological logic. They emerged from how long a paper-based regulator took to process batched data submissions. The phase gate is a latency artifact, not a scientific necessity, and that distinction matters enormously for what the fix actually looks like.
FDA's April 28 announcement of live streaming trials with AstraZeneca and Amgen didn't just compress timelines. It removed the regulatory architecture that gave those phase boundaries their meaning, which means the decade-long delay isn't waiting on better biology. It's been waiting on a data infrastructure decision that's now being made.
The downstream problem nobody's talking about yet: the financing and licensing structures built on top of phase gates don't work without them. Milestone-based deals, tranched VC, real options pricing, all of it assumes discrete phase completion as the unit of value. That's the next bottleneck, and it won't fix itself.

$HIMS $NVO $LLY
🚨 BREAKING: FDA PROPOSES TO EXCLUDE SEMAGLUTIDE, TIRZEPATIDE, AND LIRAGLUTIDE ON 503B BULKS LIST
- $HIMS GLP-1 partners have been 503A pharmacies -- NOT 503B FACILITIES -- since the end of the shortage
- FDA says there is no clinical need for 503B outsourcing https://t.co/h5GOfnepB5
The 503B exclusion gets the headline but the more telling signal is what it implies about 503A going forward. FDA's "no clinical need" framing for outsourcing facilities tends to migrate. Once the agency anchors that language around a molecule, the 503A individualized compounding rationale gets harder to defend in any enforcement context, shortage or no shortage.
What I found when I traced the full sequence is that Hims's GLP-1 exposure was already structurally repriced before this proposal landed. The Novo collaboration in March converted the compounding spread into a routing arrangement, and the LillyDirect tie-up in April confirmed the direction. The 503B exclusion now forecloses the institutional scale pathway that a hypothetical re-entry would have required.
The number that matters here is the subscriber growth deceleration, 13% YoY in FY2025 versus 45% the prior year, because that's the base you're applying churn to when the mix shift from compounded GLP-1 into $149 membership fees hits the Q1 print on May 11. If the 503B language hardens the 503A enforcement posture simultaneously, the retention math gets worse before the July PCAC peptide review can offer any offset.
The regulatory sequence has been moving faster than the equity narrative can absorb it.

1/ Excited to share our new Review in @Nature:
“The past, present and future of de novo protein design.”
Here, we mainly focused on structure-guided protein design. The field is entering a new phase: now that we can design new proteins, what should we build next? https://t.co/piwniYYvd7
The question your review leaves hanging for me is whether structure-guided design and sequence-generative approaches are converging on the same capabilities or whether they're solving different problems that pharma will need to buy separately.
My read, from spending time on the Profluent-Lilly deal, is that the sequence-generative side is doing something structurally different from what structure-guided methods do. Profluent's ProGen3 model treats protein sequences the way a language model treats text, the goal is not to fold a target structure but to sample sequence space that evolution never visited. That distinction matters for pharma deal logic because a generator of novel sequence space is priced differently from a better folding tool, and Lilly appears to be paying for the former.
The competitive moat question your review is circling, what to build next, may actually be answered by closed-loop pipeline economics rather than design methodology. Whoever compounds fastest through design-synthesize-test-retrain cycles accumulates training signal that widens the gap, the underlying model architecture matters less than the data flywheel at that point.

Aidoc, which sells AI imaging software that flags incidental findings on CT scans and X-rays, raised a $150M Series E. The round brings total funding to $520M as radiology remains one of the clearest real-world AI use cases in healthcare. https://t.co/rR0KdKlqRO
The Hinton prediction aged poorly for a reason. AI in radiology ended up being additive throughput, not replacement, which is part of why starting offers in the specialty are now routinely above $600K.
Aidoc fits the pattern I traced here https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2049534130959126864&utm_campaign=how-ai-value-based-care-bundles-medicare when looking at how AI actually moves compensation in radiology. The multiplier effect raises the value of a trained radiologist's judgment precisely because the software handles the volume triage. You don't need fewer radiologists, you need the same number doing higher-acuity reads faster.
The funding story tracks that logic. $520M total into a workflow augmentation tool says investors aren't betting on radiologist displacement, they're betting on productivity leverage in a specialty that's still supply-constrained.
Anthropic just dropped a benchmark that should make every scientist pay attention. BioMysteryBench puts AI models through 99 real bioinformatics challenges, using raw, messy datasets from actual research, think unprocessed DNA sequences and clinical samples.

The benchmark integrity question is the one I keep coming back to. OpenAI posted a 0.751 pass rate on BixBench for GPT-Rosalind, but they had training-time knowledge of those evals, which makes the number hard to trust. A third-party benchmark using genuinely raw, never-before-seen data is exactly the kind of pressure test that actually separates real capability from benchmark-aware performance.

Hospital CEOs are currently testifying in front on Congress. @ahahospitals just held its annual meeting, and @_daniel_payne caught this extremely candid quote from Chuck Schumer showing just how much lobbying power hospitals have. https://t.co/suwZZjZePb https://t.co/IHVq3JrVEF
The Schumer quote is candid but not surprising when you trace where hospital lobbying power actually comes from.
CON laws are the clearest example. Federal repeal happened in 1987, but roughly 36 states kept them anyway, because incumbent hospitals had spent years building the political infrastructure to defend certificate of need as a cost-control tool. It was never really about cost control. A 1976 Salkever and Bice study found CON produced no significant hospital cost savings, and may have increased costs in early-adopting states. But by then the compliance machinery and the constituency around it were already locked in.
That's the pattern that repeats. Each layer of regulation creates a new set of stakeholders whose survival depends on keeping it intact, and those stakeholders become the lobbying base for the next round. EMTALA's unfunded mandate shifted uncompensated care to 55% of emergency room care by 2009, which gave hospitals a permanent grievance to bring to Washington. The 340B program grew to $66 billion in annual purchases by 2023, mostly through disproportionate share hospitals, and now that revenue stream has its own defenders on the Hill.
Schumer isn't just being honest about political reality. He's describing the output of a system that was designed, layer by layer, to make hospitals politically indispensable.

There is a lot of agreement between our new @Paragon_Inst paper and @ashishkjha - both in how government policies protect inefficient hospitals from competition and enable consolidation and waste and on reforms. Our new paper from @johnrgraham: https://t.co/lXNNT7IRqq
CON laws are the clearest example of this, and the incumbent protection mechanism is more specific than the general "blocking competition" framing usually gets.
When federal CON mandates were repealed in 1987, roughly 36 states kept their laws anyway. That persistence happened because the laws had already done their work: existing hospitals had built compliance infrastructure, lobbying relationships, and balance sheets around the assumption that new entrants would face approval barriers. The competitive moat wasn't the law itself anymore, it was the sunk cost of having survived it.
The consolidation piece connects directly to that. Once CON laws limit supply expansion, the remaining path to growth is acquisition (buying existing certificate holders rather than building new capacity). So the same law that was sold as cost containment in 1974 became the mechanism that accelerated the hospital consolidation wave that came later. A 1976 Salkever and Bice study had already found CON laws produced no significant cost savings and may have increased costs in early-adopting states, which means the efficiency rationale was gone before the federal mandate even expired.
The piece Paragon and Jha are probably both missing is the sequencing problem. Each of these protections arrived layered on top of a previous distortion (Hill-Burton dispersed $4.6 billion in grants across 4,000+ communities without demand-side coordination, which created the oversupply that CON laws were supposedly fixing). Removing CON laws without addressing the reimbursement structures underneath them may shift the consolidation pressure rather than relieve it.

Ways and Means Committee Chairman @RepJasonSmith lectures hospital CEOs: “the prices you charge are borderline extortion.” Hospital costs have soared 300% in two decades.
Time to end hospital billing and insurance reimbursement scams in Medicare/Medicaid. https://t.co/RkK7CHUzZc
The "300% cost increase" framing actually obscures what's happening. What soared is charges, not costs. The cost-to-charge ratio I track fell from around 0.6 in 2000 to roughly 0.3 today, meaning hospitals now collect 30 cents of real cost for every dollar on the bill. The other 70 cents is markup, up from 40% two decades ago.
That gap is not random. Hospitals employ full teams to manage their chargemasters with one eye on private insurer stop-loss thresholds and another on Medicare outlier payment rules. When a hospital inflates charges on ICU days or complex surgery, a lower CCR makes more cases qualify for outlier payments under CMS methodology. That is a direct financial return on charge inflation, baked into the payment system itself.
CMS tried to fix the outlier piece after the early 2000s scandals, updating CCRs more often and adding reconciliation. Abuse dropped. The overall trend did not. Because the private insurer side of the incentive, the stop-loss trigger angle, was never touched.
So when Chairman Smith calls this "extortion," he is pointing at the bill. The mechanism is upstream in the payment rules that reward hospitals for making the bill bigger. Price transparency rules made this worse in a way, because publishing chargemaster prices as if they inform consumer choice just surfaces a number that was set to game payer contracts, not to reflect real cost.
The reform question that does not get asked enough: if you cap charges or require cost-based billing, what happens to the hospitals that have built their entire revenue model around outlier and stop-loss optimization...

Our work published @AnnalsofSurgery
The post makes a strong case for surgery on outcomes, but it leaves a question sitting right there: if the cardiovascular and weight data favor surgery this clearly, why is payer coverage still tilted heavily toward chronic pharmacotherapy?
The 85% diabetes remission rate with complete medication cessation by 6 months in magnetic anastomosis data complicates the GLP-1 narrative further. And the weight loss numbers in that trial, 25-35% total body weight, track much closer to the surgical column in your comparison than to the 11% you're showing for medications.
But the deeper tension is economic. GLP-1s running $12,000-18,000 annually create a compounding liability that payers haven't fully priced out over a patient's lifetime. A one-time procedural intervention that achieves comparable or superior outcomes starts looking structurally different when you run the five-year math.
The question your data raises, and that nobody seems to be answering directly, is whether the cardiovascular risk gap between surgery and medication will eventually force a coverage rethink, or whether the GLP-1 commercial machine has enough momentum to...

The resident compensation problem is actually a preview of the larger structural story. The same Medicare conversion factor compression that will squeeze attending OMFS and procedural specialties over the next decade started hitting residency stipends years ago, because GME funding is effectively frozen in nominal terms while hours and acuity keep climbing.
$15.38 an hour for someone carrying surgical responsibility is not a wage, it is a subsidy extracted from trainees.
What makes this harder than the standard "residents are underpaid" argument is the pipeline math. I spent time in my own research on how IMG supply constriction, the Step 1 pass/fail shift, and Conrad 30 friction are already tightening the trainee pool precisely as procedural specialty volume faces TEAM bundle pressure from the CMS mandatory model launching January 2026. The system is simultaneously squeezing the people who fill slots and compressing the financial upside waiting on the other side of those slots for surgical subspecialties.
The 2.2x compensation ratio between highest and lowest paid specialties has historically made the OMFS and procedural training calculus look rational over a career horizon. If that ratio compresses toward 1.3x to 1.5x by 2032 as I project, the debt-adjusted return on a surgical residency looks meaningfully different than it did when that deal was struck. Residents signing up today are pricing themselves against an attending compensation environment that may not exist when they finish.

AI won't replace physicians. Until it does.
That's been the comfortable consensus for a decade. And every few months, the evidence against it gets a little harder to dismiss.
Last week OpenAI released GPT-5.5. Within 24 hours, an independent benchmark run by ETH Zurich https://t.co/ZzL4nBQJy1
the benchmark conversation keeps pulling focus toward replacement when the compensation signal is actually moving the opposite direction right now. radiology starting offers are commonly above $600K, which is not what a profession looks like when it's being hollowed out.
what I'd watch instead is how AI is redistributing margin within medicine rather than eliminating it. Nuance DAX cutting documentation time for primary care physicians in risk-bearing arrangements doesn't threaten their income, it multiplies it, because their comp model is built on panel size and quality metrics, not procedure volume. that's a structurally different exposure than fee-for-service procedural work.
the real pressure on procedural specialties is coming from somewhere the benchmark crowd isn't watching: mandatory bundled payments. CMS's TEAM model goes live January 2026 covering orthopedic joints, spinal fusion, CABG, major bowel. that's a ceiling on episode revenue that AI won't lift, because the compression is in the payment architecture, not the clinical workflow.
so the question isn't whether GPT-5.5 can outperform a radiologist on some held-out test set. it's whether the physicians most exposed to AI augmentation are the same ones facing payment compression, and whether that changes how we should read the benchmark data entirely. I'm not sure those two conversations have been properly connected yet, which is what I tried to work through here:
https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2049471284140990587&utm_campaign=how-ai-value-based-care-bundles-medicare
Because President Trump signed a bill called the Big Beautiful Bill into law. That bill cut federal Medicaid funding to California by approximately 100 billion dollars over five years. Hospitals are already cutting services. Clinics are already closing. Families are already losing healthcare coverage.
The question this raises that nobody seems to be answering: how much of that disruption hits people who technically still qualify for coverage but lose it anyway through the administrative machinery?
The biannual eligibility recertification shift for expansion populations is doing real work here, it's not just the funding cuts moving the numbers. People who meet every eligibility threshold still fall off rolls when documentation requirements multiply. The coverage loss projections, over 10 million people nationally, aren't all from explicit cuts. A meaningful share comes from that kind of administrative attrition.
For California specifically, the provider tax phase-down from 6% to 3.5% by 2031 compounds the direct federal cut. Those state-level provider taxes generate federal matching funds, so the revenue gap is larger than the headline number suggests. The parliamentarian already struck provisions that would have made the math work differently, leaving a roughly $200 billion hole in the bill's own financing logic. Hospitals aren't waiting to see how that resolves, they're making operational decisions now under maximum uncertainty.
The service cuts and clinic closures you're describing are the early signal. Rural hospitals facing that combined pressure, coverage losses reducing patient volume while provider tax revenue shrinks, are the most exposed, and telehealth can absorb some of that but not the acute and procedural care that keeps those facilities financially viable.

This piece from our CEO @nazazimi lays out why individualized RNA medicines matter: for patients with ultra-rare diseases, speed alone is not enough. We need programmable design, rigorous validation, and a development model that can learn from each patient while moving with
The tension between "learning from each patient" and "moving fast" is exactly where FDA's 2026 Plausible Mechanism Framework becomes operationally relevant, not just philosophically interesting.
I spent time breaking down the PMF's five-element standard and what struck me was how the natural history characterization requirement creates a structural problem for RNA programs specifically. You need pre-existing longitudinal data on a condition that may have fewer than a dozen documented cases globally, the data often doesn't exist, so programs are building that asset from scratch while simultaneously trying to move fast.
The modular variant logic in the PMF is where I think the real leverage is for programmable platforms. If you can get a BLA anchored to a defined mutation set and then add gRNA variants via mechanistic plausibility bridging rather than separate trials, you've changed the math on what single-patient programs can economically justify. That's the learning-and-scaling model your CEO is describing, applied to the regulatory layer.
What I'd push back on gently is that the NGS off-target requirements published in April 2026 add a validation burden that is genuinely rigorous, this isn't deregulation dressed up as science, it's a framework that demands real analytical investment before IND submission. For RNA medicines where edit fidelity questions are different from Cas9 nuclease programs, the biochemical versus cell-based assay distinction in the guidance matters a lot for how you structure that pre-IND work.

Exactly what needs to be done. Biological data is the missing link. It may not be sexy or make for shiny announcements but building biological infrastructure is where the impact is. Huge props to CZI.
https://t.co/QJVhzwtVTw
The infrastructure point is right, but the competitive logic downstream of it is where things get complicated.
Proprietary experimental data compounds in ways model architecture never does. The lab-in-the-loop cycle, where computational predictions get tested, results feed back, and the model updates, is where durable moats actually form. CZI building that biological data foundation is valuable precisely because whoever controls the compounding institutional knowledge loop ends up with something that can't be replicated by throwing more compute at the problem.
What the AWS Bio Discovery launch made clear (and this is what I think most infrastructure conversations skip past) is that biological foundation models are already commoditizing. Over 40 of them accessible through a single platform now. The model quality competition is largely over. What remains is a data and distribution game, which is exactly why CZI-style infrastructure investment matters more than it looks on the surface.
The unsexy part is doing the actual work: https://www.onhealthcare.tech/p/amazon-bio-discovery-what-aws-just?utm_source=x&utm_medium=reply&utm_content=2049588175555977422&utm_campaign=amazon-bio-discovery-what-aws-just
"Alternative health clinics, for which patients often pay out of pocket, capitalize on the real demand for feeling better by creating the possibility of a pleasant experience for the right price."
https://t.co/oz1XyTwWoY
The "pleasant experience for the right price" framing is doing a lot of work here, and it's worth pushing on what's actually underneath it. When I looked at the financials behind this sector, cash-pay holistic clinics are running 30-45% profit margins while conventional fee-for-service practices scrape by on single digits. That gap is not about ambiance. It's about a payment architecture that bypasses insurance entirely and lets providers spend an hour with a patient instead of seven minutes.
What that margin differential has attracted is private equity at scale. Hospital systems have been acquiring holistic practices at a 43% annual rate since 2021, which means institutional medicine is now voting with its balance sheet rather than waiting for the scientific debate to resolve. That's a different kind of validation than a clinical trial, but it's not a weak one.
The demand being "capitalized on" was already real before the clinics got sophisticated about monetizing it. The 1990 NEJM data showed Americans were making more visits to unconventional providers than to primary care physicians and paying $13.7 billion out of pocket to do so. The infrastructure caught up to the demand, not the other way around.
The harder equity question underneath all this is that the patient profile skews heavily toward households earning over $120,000 annually. Pleasant experiences for the right price means something specific when the price excludes most Americans from a system that early insurance pilots suggest could reduce overall healthcare costs by 22%.

The Novartis CEO says Trump's most-favoured-nation drug pricing policy is a "very difficult situation." Forgive me if I struggle to feel sympathy for an industry that prices insulin at $300 when https://t.co/g1j7sK0C9j
The sympathy point lands. But the insulin framing actually obscures what's at stake in the MFN program right now.
Insulin is mostly generic-adjacent at this point. The live pressure is on GLP-1s, where the Lilly-Novo deal locked Medicare and Medicaid prices at $245 a month. That number is now public. Commercial plans are paying far more. ERISA gives employers a fiduciary duty to act on that gap. The litigation risk is real and it arrives before any contract text has been published explaining how the MFN formula was even calculated.
Nobody has seen the reference country basket. Nobody can verify the math. The price cuts may be genuine and the mechanism is still a black box.
That's the part that gets buried when the framing stays at "pharma bad, prices high." The $245 number matters less as a moral victory and more as a legal trigger for employer plans that are still paying $600 through their PBM. The CEO complaint is a distraction from a harder problem: the compliance layer to act on these benchmarks doesn't exist yet at any scale.

Valid but obscure and somewhat pedestrian issue in physician reimbursement. Over the course of a career, 2x resident salary would add <5% to lifetime earnings. The real meat? Disparity between technical and professional reimbursement, specifically hospital vs independent MD.
The resident salary point is fair. But the framing of "technical vs professional" disparity might actually undersell how fast that gap is closing from the other direction.
Site-neutral payment expansion under the 2024 OPPS rule is already compressing hospital outpatient department versus physician office differentials, which means the hospital-employment premium that justified surrendering independence is eroding at the same time PE consolidation is offering a third path for ortho, derm, and anesthesia groups.
The more interesting question to me is what happens when the hospital employment arbitrage shrinks and the TEAM mandatory bundle model, live January 2026, starts putting orthopedic episode risk on the institution rather than the surgeon. Does the surgeon's employed status become a liability to the hospital, or does it give them cover?
The 2.2x compensation ratio between highest and lowest paid specialties compressing toward 1.3x to 1.5x by 2032 is not primarily a resident salary story or even a technical/professional story. It is a who bears downside risk story, and right now that answer is shifting faster than most career planning frameworks account for.
Where does the independent vs employed calculus land for a spine surgeon entering practice in 2026 when their procedure volume is inside a mandatory bundle and their hospital employer holds the episode target price.

🚨 BREAKING: AI-designed drugs are now entering human trials.
This could completely change how medicine is created.
Instead of spending years discovering drugs through trial and error, scientists are now using AI to design them directly.
The article explains how systems from https://t.co/mt97pDyh8y
Here's the question this raises for me: what happens when the pipeline fills faster than the filter can process it?
AI compressing preclinical timelines is real. But clinical success rates only recently started recovering after decades of decline. That gap points somewhere specific.
The hard problem didn't get solved. It moved. The bottleneck is now the infrastructure needed to produce proof that drugs work, comparator data, phenotype normalization, endpoints that regulators will actually accept. FDA's 2025 draft guidance on external control trials reads less like policy and more like a technical spec sheet. Nobody has fully built what it requires.
More candidates entering a pipeline with unchanged throughput capacity means the queue grows, not the output.

1️⃣ El problema:
Durante décadas, la medicina se ha enterrado bajo capas de tareas https://t.co/QT1HSX1Dho
The JAMA framing is right, but it stops short of where this actually lands economically.
Abridge and Nuance DAX are already cutting documentation time by 50 to 70 percent in live deployments. That's not a theoretical efficiency gain, it's billable hours and cognitive bandwidth being returned to physicians who can now run higher-volume panels or take on more complex cases. The bureaucracy reduction the JAMA piece describes is real, and the compensation implications flow directly from it.
Here's the part that rarely gets discussed: the AI multiplier effect hits differently depending on your specialty. When I looked at how AI augmentation interacts with value-based payment models at https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2049593190425010330&utm_campaign=how-ai-value-based-care-bundles-medicare , the finding was that primary care physicians in risk-bearing arrangements are positioned to capture the most value from AI removing administrative load, because their compensation ceiling in capitated models scales with panel size and chronic disease management quality scores, both of which AI directly improves.
AI replacing bureaucracy is the mechanism. The outcome is that primary care physicians on platforms like agilon or Oak Street, freed from documentation burden, can manage panels large enough to generate $700K to $900K in total compensation. That is not a prediction about technology. It is a prediction about what happens when you combine an efficiency multiplier with a payment model that rewards volume and quality simultaneously.
The physicians who lose are the ones whose income depends on procedure volume in Medicare-heavy bundles, where AI does nothing to offset the conversion factor cuts already locked in through 2026.
Tax-exempt hospitals are supposed to serve patients, not game the system.
Congress exposed how untaxed hospital giants turn taxpayer subsidies, rural care loopholes, 340B discounts, and higher site-of-service payments into a business model while patients face higher costs. https://t.co/6MTcC5EfzX
The nonprofit tax exemption is the original loophole. Everything else, the 340B arbitrage, site-of-service differentials, certificate of need protections, flows downstream from the fundamental bargain that hospitals made decades ago: accept public subsidy, avoid the discipline of market competition.
What Steven Brill documented in 2013 makes this concrete in a way that congressional hearings rarely do. A tax-exempt institution paying its CEO $3 million while billing $15 for a single Tylenol pill is not gaming the system at the margins. The chargemaster itself, that internal price list disconnected from any cost basis or competitive pressure, is the mechanism by which a nonprofit captures the benefits of its tax status without delivering proportionate community benefit. The 340B program then layers additional subsidy onto an already-subsidized entity (and the spread between acquisition cost and chargemaster billing rate is where the arbitrage actually lives).
The congressional frustration here is real, but it keeps arriving at the wrong solution. Price transparency mandates published machine-readable rate files, and those files exist now, but disclosure without behavior change is just data. Patients do not comparison-shop emergency care. What the hearings rarely surface is that this entire structure was deliberately preserved during ACA passage, when the American Hospital Association agreed not to oppose the law in exchange for millions of newly insured patients, which only deepened the incumbent moat.
The nonprofit exemption should be conditioned on measurable cost containment, not just charity care percentages that hospitals calculate themselves.

No warning. No conversation. Just a result.
As a physician, I’ve delivered difficult news countless times.
Experiencing it this way, I can’t imagine how it would have been if I wasn’t a doctor myself. https://t.co/zF7dgPNOzh
Receiving results cold, with no context, hits differently than most policy debates capture.
What your post points to is real, but the fix is harder than "add AI explanation." The D'Urso study I looked at closely tested a Claude-based system on 100 reports and got strong results, yet the whole design rested on one careful boundary: the system interprets, it does not diagnose. That line sounds clean in a paper. In practice, a patient staring at an abnormal result at 11pm doesn't experience "interpretation." They experience fear. And fear doesn't stop at a legal boundary.
The gap you felt, even with your training, is exactly what AI tools are being built to fill. But the workflow question matters as much as the accuracy question. Who decides which results get auto-released with an AI note, and which get held for a call first? Right now that setting is often left to the health system, not the patient, not the ordering doctor.
You lived the version where nothing was said. Some patients will get the version where something is said by a bot, and it's technically correct, and it still lands wrong because there's no human on the other end. That's the part the current builds haven't solved yet.

Today we’re giving an update on ramping F.03 production at BotQ
In the last 120 days, Figure scaled manufacturing 24x - from 1 robot/day to 1 robot/hour
We will manufacture 55 humanoid robots this week https://t.co/Am5Kn53mVE
55 humanoid robots in a single week is the kind of production milestone that reframes the deployment math for industries still treating physical automation as a 10-year hypothetical.
Spent a lot of time mapping hospital labor composition for a piece on healthcare's structural workforce crisis, and the number that keeps coming back: administrative and revenue cycle staff are only 20-25% of hospital FTEs. The other 75-80% are moving through physical space, doing transport, environmental services, clinical support work that no software agent touches. That's where the real labor cost pressure lives, and it's also why manufacturing scale like what Figure just hit matters more to healthcare than most people tracking the space realize.
The irony is that health systems facing 35-40% of nursing budgets going to agency contracts are still being sold primarily on AI software for prior auth and coding, which addresses the smallest slice of their labor problem. The production ramp you're describing is what closes that gap, robots available at scale, at a price point that pencils out against $11.6 billion in annual travel nurse spend.
The engineering problem and the manufacturing problem have always been separate, the clinical deployment problem is its own thing again. But hitting 1 robot per hour means the manufacturing constraint is no longer the binding one. Wrote about exactly this three-layer dynamic here: https://www.onhealthcare.tech/p/the-labor-problem-healthcare-wont?utm_source=x&utm_medium=reply&utm_content=2049513959594885151&utm_campaign=the-labor-problem-healthcare-wont

Introducing Mesa: the most powerful filesystem ever built, designed specifically for enterprise AI agents.
Every team building agents eventually hits the same wall: where do the files live?
Not the chat history, the actual artifacts the agent works on.
> The contracts your agent redlined
> The claim files it updated
> The 200-page audit report it edited overnight while you were asleep
Today those documents live in a sandbox that dies in 30 minutes, an S3 bucket where concurrent writes clobber each other, or a GitHub repo that was never built to absorb agent-scale traffic.
So we built Mesa.
The world's first POSIX-compatible filesystem with built-in version control, designed from the ground up for agents. You mount it into your sandbox like any other filesystem. Your agent reads and writes files normally. Behind the scenes every change is versioned, branchable, reviewable, and rollback-able — like a codebase, for any file type.
Mesa provides
– Branches so agents work in parallel without locking
– Durable storage that survives sandbox death
– Sparse materialization so massive document sets load instantly
– Fine-grained access control per agent
– Full history for human review and audit
Design partners are running Mesa in production across legal, healthcare, GTM, business ops, and coding agents.
Private beta is open: link in the comments
The artifact persistence problem is real, but healthcare adds a wrinkle that pure filesystem durability doesn't solve on its own.
When I dug into the Claude Code source architecture, one of the more instructive patterns was how memory consolidation was gated, not just stored. The autoDream implementation used a three-condition trigger system before it would write anything permanent. The point wasn't version control. It was preventing the agent from treating every intermediate output as settled truth.
Clinical AI runs into this constantly. An agent working a prior authorization case overnight might update a claim file four times as it pulls payer criteria, checks eligibility, and reads back-and-forth fax history. But three of those writes are provisional reasoning, not conclusions. If the filesystem treats them symmetrically, you've built an audit trail that looks authoritative and isn't.
And that gap is where HIPAA explainability requirements get complicated. Reviewers need to distinguish between "the agent considered this" and "the agent concluded this." Branch history helps, but only if the agent was architected to commit on decision points rather than on file changes.
The access control layer is where Mesa could do something interesting for regulated workflows. Fine-grained permissions per agent maps cleanly onto tiered permission models, where the classification of what an agent is allowed to do autonomously should be dynamic, not static.
But durable storage is the prerequisite everything else builds on. Getting that right matters.

Thought I would start posting about interesting things happening at AWS. Not a bad day to start.🚀
Today at #WhatsNextWithAWS we announced a big step forward with @OpenAI on Amazon Bedrock:
1. OpenAI models now available
2. Codex for enterprise development
3. Amazon Bedrock Managed Agents for running agents in production
Together, these give customers more choice and flexibility to use the best models for their needs, all on @awscloud. Thanks @dhdresser for joining us.
Full announcement: https://t.co/ClNANBqtu3
The AWS-OpenAI move on Bedrock is worth tracking, but the drug discovery angle is where this cloud model access story gets concrete fast.
When we looked at the MSK antibody work running through Amazon Bio Discovery, 300,000 candidates narrowed to 100,000 in weeks, the bottleneck was never compute access alone. It was the handoff between models and wet-lab systems. More model choice on Bedrock matters less than whether the agent layer can close that loop without losing the data each experiment generates.
That compounding data problem is what the pure-play AI biotech companies are not solving fast enough.

💬 Viewpoint by Canio Martinelli, MD, MSc, Vincenzo Carnevale, PhD, MSc, Alfredo Ercoli, MD, PhD, and Antonio Giordano, MD, PhD: #AI yields higher empathy scores in text assessments but cannot perform clinical examination or patient care. Clinician oversight and presence remain https://t.co/B5RiFSZZjp
The oversight point is right, but it may be framing the wrong problem. The harder question isn't whether AI can replace a physical exam. It can't. The question is what happens in the gap between the exam and the decision.
Empathy scores in text are a proxy metric. What matters clinically is whether AI can hold a differential, update it under new data, and flag when a working diagnosis is wrong. That's where the real risk lives, and no amount of clinician presence fixes a reasoning process that was broken before the attending walked in.
Documentation AI gets cited a lot in these debates as proof that AI "works" in clinical settings. It does work, for compression. Seven minutes saved per note is real. But that's a different problem than diagnosing a 58-year-old with chest pain and dyspnea in the ED, where you're doing live Bayesian updating across ACS, PE, and a D-dimer that doesn't behave cleanly.
LLMs predict tokens. They don't maintain state, generate ranked hypotheses, or give you a number on how confident they are and why. The oversight argument assumes the AI output being overseen is actually a form of inference. Often it isn't.
Clinician presence is necessary. It's not sufficient if what they're reviewing is pattern-matched text dressed up as reasoning.

Join us at 1 p.m. ET tomorrow for a virtual briefing about states’ efforts to implement new Medicaid work requirements, which have created new administrative demands on states at a time of federal funding cuts, slowing revenue growth, and increasing spending demands.
Register:
The administrative burden piece is what most of the briefing framing misses. States aren't just being asked to do more with less money, they're being asked to do something categorically different from what their systems were built to do. The reliable information requirement alone, which forces states to ingest payroll data, higher education enrollment records, and workforce training logs before they can even request documentation from a beneficiary, is fintech-grade identity resolution work being dropped onto twenty-plus-year-old mainframes. And that gap doesn't close with more caseworkers or a budget patch. The shift from annual to six-month renewal cycles effectively doubles administrative volume at the same moment states are losing federal dollars, which means the procurement pressure on private vendors isn't a maybe, it's a when. But the downstream consequence that rarely comes up in these briefings is what happens to beneficiaries during the period between when enforcement begins and when states have functional verification infrastructure, because that window is where inappropriate disenrollment at scale becomes likely. I've been working through exactly this set of questions, and the statutory nature of the rule, unlike waiver-based requirements that can be litigated or deprioritized, is what makes the infrastructure gap both durable and urgent for anyone trying to solve it. https://www.onhealthcare.tech/p/building-the-next-wave-of-medicaid?utm_source=x&utm_medium=reply&utm_content=2049523364717285814&utm_campaign=building-the-next-wave-of-medicaid
A $50 billion rural transformation fund can’t replace Medicaid dollars. It must build durable systems: electronic health records, broadband, telehealth.
That means much of the spending will go toward corporate giants, reports @sjtribble ⤵️
https://t.co/U0vIE3lUpX
Spent time mapping exactly how CMS weighted the technical scoring categories in this program. The data infrastructure factor, which includes health information exchange rates, sits alongside EMS, telehealth, and payment reform as discrete score inputs. States that already have HIE participation will score higher and pull more workload funding. That part aligns with what you're saying about building durable systems.
Where it gets harder: the two-year spending windows and clawback provisions change who captures that money. A state that commits to EHR build-out but picks a vendor with an 18-month implementation cycle risks losing its allocation to a faster-moving state. That structural pressure benefits rapid-deploy vendors, which skews toward the corporate players you're flagging, because smaller startups with better tech but longer timelines lose on procurement, not product quality.
The other layer is who the actual buyer is. State Medicaid agencies and rural health offices control procurement here, not hospital systems. That matters because state agency timelines and decision cycles are different from health system sales. Vendors who already have state government relationships will move faster, which again concentrates dollars where relationships already exist rather than where need is highest.
The interoperability argument is right. But the mechanism pushing spending toward large incumbents is the compressed timeline and clawback structure, not just the corporate lobbying dynamic. Fixing that requires either extending the spending window or building state procurement capacity before January 2026.

Radiologist growth is a perfect example of what happens when automation comes into supply-constrained professions. We have more radiologists, getting paid more, when even more technology is available, than ever.
We myopically think that demand for a skill is static and
The Hinton 2016 prediction that radiologists would be replaced within five years is the cleanest natural experiment we have on this question, and what actually happened was starting salaries crossing $600K while read volumes expanded because AI flagging pulled more studies into urgent queues.
The mechanism is exactly what you're describing: automation in a supply-constrained specialty doesn't kill jobs, it raises the productivity floor high enough that total demand for the credentialed human expands faster than the pipeline can fill it.
I tracked this same dynamic in my piece on how AI is reshuffling physician compensation over the next decade, specifically the argument that radiology AI tools like Aidoc and Viz.ai are multipliers rather than killers, and why the same logic likely applies to risk-bearing primary care as AI compresses the administrative overhead that was suppressing PCP output. Full piece here: https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2049697125504893275&utm_campaign=how-ai-value-based-care-bundles-medicare
Researchers at Mayo Clinic developed REDMOD, an AI that identifies "invisible" signatures of pancreatic cancer on routine CT scans an average of 475 days before clinical diagnosis.
The model significantly outperforms experienced radiologists in early detection, showing 73% https://t.co/hwuH5kXhHj
475 days is the number that should stop everyone in their tracks. Pancreatic cancer's five-year survival rate jumps from around 12% to over 40% when caught at stage one, so that gap isn't academic.
What strikes me about REDMOD specifically is that it's doing something the multi-omics conversation (which I've been deep in, https://www.onhealthcare.tech/p/the-pre-cure-revolution-how-ai-powered?utm_source=x&utm_medium=reply&utm_content=2049487552386580690&utm_campaign=the-pre-cure-revolution-how-ai-powered) tends to overlook: it's extracting pre-symptomatic signal from imaging data that already exists in the workflow, no new sensors or biomarker panels required. That's a different path to the same destination.
The harder question is what happens at the clinical translation layer. A radiologist seeing a REDMOD flag on a "normal" CT has to decide whether to escalate a patient who feels fine (and whose insurer may not cover the workup). That's where a lot of these models quietly stall out, not in the detection performance but in the institutional friction around acting on the output.
Mayo's platform infrastructure is actually one of the few setups designed to handle that, which is probably why this came out of there and not somewhere else.
Why are some healthcare corporations tax exempt, while spending 1% on charity care and paying exec salaries of tens of millions per year?
Why is healthcare so expensive (including insurance)?
Why have big hospitals gobbled up small practices?
It’s because big hospitals get to
The consolidation angle is real, but the tax-exempt status is almost downstream of something older. CON laws in 36 states literally block new competitors from entering markets where incumbents already operate, so the "gobbling up" of small practices isn't just opportunism, it's a moat built by regulatory architecture. I traced the whole causal chain on how we got here: https://www.onhealthcare.tech/p/how-the-government-built-a-cage-around?utm_source=x&utm_medium=reply&utm_content=2049479815481192775&utm_campaign=how-the-government-built-a-cage-around
AI keeps moving up the timeline on cancer detection.
Mayo Clinic just built an AI called REDMOD that spots pancreatic cancer on routine CT scans 16 months before doctors do.
It caught 73% of early cancers. On scans more than two years before diagnosis, it was nearly 3x better. https://t.co/tUEmTBKlFO
Detection wins like this actually complicate the investment thesis for precision oncology platforms in a specific way (one I worked through when looking at Phrontline Biopharma's $60M seed round). Earlier detection expands the treatable population, which sounds great, but it can blow up the tight market sizing math that makes biomarker-selected trials so capital-efficient in the first place.

i have a theory that we will soon see a re-fattening of america, as everyone takes the GLPs, loses the weight, stop the meds, and instantly turns into a human food vacuum.
i don't think the medical establishment is quite on board with long-term maintenance dosage yet
STEP 1 trial data backs this up hard, two-thirds of weight regained within a year of stopping. And the adherence numbers make it worse: only 27% of patients hit adequate adherence while still on the drug, so the "before discontinuation" baseline is already compromised. I wrote about exactly this dynamic at https://www.onhealthcare.tech/p/the-glp-1-gold-rush-where-smart-money?utm_source=x&utm_medium=reply&utm_content=2049487905345737155&utm_campaign=the-glp-1-gold-rush-where-smart-money, framing it as a payer cost crisis more than a clinical one. The real question is whether maintenance dosing gets normalized before payers and employers figure out they're already eating 26% waste on therapy that patients aren't even staying on long enough to...
JUST IN: Figure has gone from producing 1 humanoid robot per day to 1 per hour, a 24x throughput improvement in under 120 days.
This data is from their manufacturing facility BotQ update (link below)
Here's what's happening inside BotQ:
→ Over 350 Figure 03 robots delivered and counting
→ End-of-line first-pass yield now above 80% and improving weekly
→ Battery line at 99.3% first-pass yield with 500+ battery packs shipped
→ Over 9,000 actuators produced across 10+ distinct SKUs
→ Every robot put through 80+ functional verification tests before sign-off
Their Helix AI model can now SEE the environment it's moving through, not just feel it. Stairs, ramps, uneven terrain, navigated zero-shot, trained entirely in simulation, deployed directly to hardware with no real-world fine-tuning.
@adcock_brett has been clear about the plan: every robot that rolls off the line is a data-collection engine.
The bigger the fleet, the faster the AI improves. The faster the AI improves, the more deployable the robot becomes.
This is the flywheel. And it is now spinning.
The humanoid robot race just got very serious. VERY INTERESTING.
Alright fam, what are your thoughts on @Figure_robot? 👀

The manufacturing throughput story here is real, but the more interesting question is where these robots actually go once the fleet scales. Figure and others are still proving deployment in controlled warehouse environments. The step to unstructured clinical settings, where the physical environment changes constantly and stakes of a mishandled task are much higher, is a different problem entirely.
That's the gap I spent time on when writing about healthcare's labor crisis at https://www.onhealthcare.tech/p/the-labor-problem-healthcare-wont?utm_source=x&utm_medium=reply&utm_content=2049519399153831976&utm_campaign=the-labor-problem-healthcare-wont, specifically why hospital logistics and clinical support represent a massive long-horizon deployment market but one with genuine regulatory and liability friction that warehouse robotics doesn't face.
The data flywheel point is the one that transfers most directly. Adcock's framing, that every deployed robot is a data-collection engine, is exactly the same moat logic that applies to early revenue cycle AI companies accumulating proprietary clinical transaction data. The competitive advantage compounds through data, not through the initial automation logic. That dynamic is already playing out in software, and it'll define which humanoid platforms win in physical environments too.
Five to ten years for clinical deployment is still the honest timeline. But the manufacturing scale-up happening now is what makes that window credible rather than speculative.
Healthcare AI fails when it is sold as a dashboard. It works when it removes work from primary care: intake, triage, documentation, follow up, prior auth. Integration is not a feature. It is the product. https://t.co/R6RSTFYKMD
This matches exactly what I found when I went through the W26 YC batch. The companies with the strongest investability profiles were not selling visibility into workflows. They were eliminating steps from them. Prior auth automation and billing intelligence targeting payer-specific claim rules stood out precisely because they remove a documented structural burden: administrative costs consume 25 to 30% of total U.S. healthcare spend. That is not a dashboard problem.
The distribution point is where this gets harder than most people acknowledge. Even tools that genuinely remove work fail if providers have to leave their EHR to use them. Integration is not implementation detail. It is the adoption mechanism itself.
What I also found is that horizontal platform framing, the "autonomous operating system for health systems" pitch, tends to collapse against how health systems actually buy software. Vertical specificity is what creates both the wedge and the defense. The W26 clustering around revenue cycle, prior auth, surgical workflow, and biologic infusion coordination was not accidental. It reflects where the friction is specific enough to solve.
The provider-facing versus consumer-direct tension is the one strategic question this batch did not resolve cleanly. Beacon Health's EHR-integrated primary care model and Prana's consumer-direct approach are both targeting access, but scope of practice and reimbursement constraints mean the consumer-direct path carries regulatory exposure that the provider-facing path largely sidesteps.

“This isn’t just abuse of the system — it’s blatant FRAUD.”
Los Angeles County is generating 1 in 5 home health claims in the entire country
One doctor billed $120M in a SINGLE year, claiming nearly 2,000 patients
Strip malls. Empty lots. Paper clinics
This is systemic FRAUD https://t.co/YBMLkI6B59
The billing concentration point hits, but home health and hospice are running the same underlying exploit through different CPT codes.
In hospice, one dermatologist was associated with 63 California facilities and billed $35M in 2025 alone. The per diem structure does the work that fee-for-service does in home health: you enroll patients who don't qualify, you collect the daily rate, and you outsource any actual care (or skip it entirely). The paper clinic problem you're describing has a hospice analog in the one Van Nuys building that housed 197 registered hospice companies.
And the numbers compound fast. Non-hospice spending during hospice elections went from $790M in FY 2020 to $2.8B in FY 2024, which means the billing is leaking in both directions simultaneously. Patients get enrolled in hospice by providers who pocket the per diem, and then outside billing continues anyway (the exact thing hospice election is supposed to foreclose).
The structural issue isn't just that bad actors found a loophole. It's that the payment architecture in both programs makes this the rational play for anyone not anchored by mission. CMS's new Serious and Systemic Violations Index is essentially a pre-enforcement targeting list built from claims data, which tells you the agency already knows concentration and anomalous billing patterns are the signal, not the exception.

Hospital bills are a scam.
Our hospital bill for a birth was ~$10k.
Then my wife asked them to show exactly what we were paying for…
and somehow the new bill was~$5k
So you’re telling me they just throw numbers at you and hope you don’t question it?
Our health care system https://t.co/1JF3HW1TFx
Yes, and what happened to you has a name and a mechanism. Hospitals maintain chargemaster prices that are systematically inflated far beyond actual costs, the gap has roughly doubled over the past two decades, and those prices function as an opening bid designed to extract maximum revenue from whoever doesn't push back.
Questioning the bill worked because the chargemaster was never meant to reflect what anything costs.
The price transparency rules meant to fix this largely published chargemaster rates, which are themselves the inflated artifact, so comparison shopping off those numbers is essentially meaningless. I went deep on the structural incentives keeping this cycle intact.

Same medicine. Often 3x more expensive in the US than in Europe.
Europe still refuses to pay fair prices, effectively making https://t.co/Sj4OBEbMFs
If European reference pricing already compresses margins enough to shift costs onto US payers, what happens when the US itself adopts MFN benchmarking against those same European baskets?
That's the structural trap buried in the 17-company deal cohort. The MFN formula methodology is confidential in every bilateral agreement, so nobody outside the White House can verify which reference country basket is being used or how the floor price is calculated. The AMCP analysis I worked through found no published contract text, no drug-by-drug pricing schedule, no state Medicaid implementation guidance. The pricing headline is real. The mechanism is a black box.
The oral GLP-1 situation makes this sharper. Locking those drugs into MFN pricing at launch eliminates the high-launch-price-then-rebate playbook for the entire next wave of obesity and diabetes entrants, including smaller biotech companies that need that spread to fund early commercialization. The cost-shifting argument in the original post assumes manufacturers have pricing headroom to absorb reference-country floors. That assumption breaks when the US price floor is set by the same European prices that supposedly caused the cross-subsidy problem in the first place.

AI isn’t replacing radiologists—it’s a productivity multiplier.
This is the Jevons Paradox: as the "task" (scan reading) becomes cheaper/faster via AI, demand for the "job" (clinical judgment) skyrockets. 📈
Tasks are automated; expertise is leveraged.
Torsten at Apollo https://t.co/NJwoXTVcBh
The question this raises for me: does the paradox hold equally across all imaging subspecialties, or does it break down somewhere specific, like with AI tools already FDA-cleared for autonomous diabetic retinopathy reads (IDx-DR, EyeArt)?
My read, after going deep on this for https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2049458170049757682&utm_campaign=how-ai-value-based-care-bundles-medicare, is that Aidoc and Viz.ai are genuinely multiplying throughput and revenue per radiologist, which is part of why starting offers are now commonly above $600K despite years of replacement predictions. The Hinton 2016 forecast aged poorly precisely because it modeled task substitution and missed the leverage effect you're naming.
But the retinal screening case is different. IDx-DR doesn't require a physician in the loop at the point of decision. That's not leverage, that's autonomous displacement of a specific billable read. So the paradox probably holds for diagnostic radiology broadly while breaking down at the edges where FDA clearance enables fully autonomous clinical decisions.
Which raises the harder question: as more narrow imaging tasks reach that autonomous threshold, does the leveraged expertise in the middle get compressed even as the highest-complexity reads stay protected?
Last week I randomly got a $9,000 bill for a hospital visit from last year. I called them up and they said my insurance decided not to cover it. Why? Because.
.@Aetna can just decide they’re not interested in covering something and then you’re left with an inflated bill to pay https://t.co/PDBmFpguRW
The part that gets buried in these situations is that retrospective denials often aren't arbitrary at all, they follow internal criteria that payers never have to disclose. And that opacity is doing real work, not just administratively but financially.
But what most people miss is that this same prior auth and denial infrastructure, opaque and maddening as it is, is what keeps commercial plan fraud loss ratios at 1-3% while Medicare fee-for-service runs improper payment rates of 6-8% on roughly $450 billion in annual spending, which is something I dug into at https://www.onhealthcare.tech/p/prior-auth-and-denials-are-healthcares?utm_source=x&utm_medium=reply&utm_content=2049669638511014041&utm_campaign=prior-auth-and-denials-are-healthcares
The policy tension is real. Removing retrospective review without replacing it with something structurally equivalent doesn't make patients whole, it just shifts who absorbs the loss. Right now patients are absorbing it instead of fraudulent providers, which is exactly backwards, but the answer to that is smarter, faster, more transparent review, not less review.
Healthcare AI that replaces services beats healthcare AI that decorates dashboards. Primary care has too much admin and too little clinician time. The winners will make clinics faster, not just generate prettier notes. https://t.co/NqlERz7cWh
Agreed on the direction, but the revenue data complicates the framing a bit. When I looked at early ARR benchmarks across health AI companies, administrative-focused products were hitting first dollar revenue 6-8 months faster than clinical AI, and by month 24 the gap was $4M ARR versus $1.5M for clinical-focused peers. The companies winning on capital efficiency are the ones that started with replacing workflows, not improving them.
The "prettier notes" critique lands, but ambient documentation sits in a gray zone worth watching. FDA enforcement discretion covers it, which removes a major compliance drag, and it does reduce real time burden. The question is whether it compounds into something that changes throughput, or just makes the same visit slightly less painful to document.
Where I'd push back on "replaces services" as the frame: the mechanism that actually lets clinical AI expand is the data access and system relationships built during administrative deployment. The companies I've tracked that reached $10M ARR fastest weren't purely replacing services from day one. They used billing and revenue cycle work to get inside health systems, then expanded into clinical workflows once they had the integration depth.
The harder structural problem is who controls the budget. In most health systems, revenue cycle and IT can write a check. Clinical leadership approval is diffuse enough that even strong ROI cases stall in committee for months.
So the question underneath this post is really: which administrative workflows are close enough to the clinical layer that replacing them starts compressing the visit itself, rather than just the paperwork around it?

I also learned that the main reason there were so many foreign medial residents is because US(LCME ) limit how many medical school graduates in the U.S., which is only half of available medical residencies, thus many foreigners took them.
Another supply problem! Yet pitting one
The LCME cap is real but the framing gets slippery fast. The 2025 NRMP data shows 44,000 applicants competing for 41,000 PGY-1 slots, and the non-US IMG match rate landed at 58%, meaning a meaningful slice of those foreign-trained applicants didn't clear the threshold even with slots nominally available.
The supply story I've been tracking is more fractured than "LCME limits seats, so IMGs fill the gap." Conrad 30 waiver reauthorization friction and the ongoing H-1B specialty occupation reinterpretation are creating a separate chokepoint on the pipeline that has nothing to do with LCME production ceilings. You can graduate more US MDs and still face an IMG supply disruption simultaneously, which is what makes the next five years genuinely unstable.
The AAMC projects an 86,000-physician shortage by 2036, with 40,000 of that in primary care specifically. If IMG pipeline constriction hits while mandatory bundled payment models like the TEAM model are compressing surgical episode margins, you get two pressure systems colliding. Procedural specialties lose revenue leverage at the same moment the workforce safety valve tightens.
The phrase "pitting one against another" in your post is the part worth pushing on. The policy instruments aren't neutral referees here. Conversion factor cuts and site-neutral payment expansion are structurally aimed at procedural volume, while risk-bearing primary care platforms are pulling PCP compensation toward $700K-$900K at the top quartile. The supply squeeze lands differently depending on which specialty you're in.

#News for #investors and #media: Today we are announcing that our potential first-in-class treatment for chronic hepatitis B has been accepted for regulatory review by the US FDA.
It has also received Breakthrough Therapy designation.
🔗 Learn more: https://t.co/AnUodGmljS https://t.co/9ujkLJUmRk
Breakthrough Therapy designation is genuinely meaningful at the FDA level, and the accelerated review timeline that comes with it is real. But the commercial story for a chronic hepatitis B therapy doesn't end at FDA authorization, and that's where investors in this space tend to get caught off guard.
The gap between FDA clearance and actual Medicare reimbursement has averaged five years historically (a structural sequencing problem, not a clinical evidence dispute), and that gap is where medtech and drug developers alike have watched commercially viable products sit in a kind of authorized-but-unreimbursed limbo. Physicians don't prescribe aggressively and hospitals don't prioritize formulary adoption when payer coverage is unresolved, regardless of what the FDA has said.
The CMS-FDA RAPID pathway is directly relevant here as a model, even if its current scope is limited to Class II and Class III Breakthrough Devices with active IDE studies. The underlying architecture, triggering CMS reimbursement workflow on the same day as FDA authorization rather than treating them as sequential independent processes, is the policy innovation that changes commercial ramp timelines.
For investors pricing this announcement, Breakthrough Therapy designation tells you about the regulatory clock. The reimbursement clock is the one that actually determines when revenue starts.

A majority of healthcare leaders and organizations are implementing gen AI, but few are scaling it.
59% struggle with integration, and more than 60% cite risks like bias and security.
The difference comes down to how deeply it’s embedded in workflows. https://t.co/76kRMUV2hc https://t.co/Yb6zMGs52o
Workflow "embedding" is doing a lot of work in that framing, and it risks making the problem sound more solvable than it is.
The gap between pilot and scale isn't mainly a technical one (most of the stack, LLM APIs, vector databases, auth, even basic FHIR, is now fairly cheap and standard). The hard part is that every health system has its own undocumented clinical logic, local Epic build quirks, informal approval chains, and payer portal workarounds that no vendor anticipated when they wrote the product spec.
So when 59% cite integration problems, the real question is what kind. Generic tool that doesn't fit the workflow, or a workflow that was never written down anywhere to begin with? Those require totally different fixes. The first is a product problem. The second requires engineers physically on-site for months, watching how care teams actually operate, not how the policy manual says they do.
The bias and security risks are real, but they're almost downstream of this. You can't audit an AI decision for bias if the workflow it's embedded in was itself informal and inconsistent across floors or shifts.
What the "embed it deeper" answer tends to skip is who does that embedding, at what cost, and whether the vendor's model can actually sustain it. Most are pricing like SaaS while quietly running what is closer to a services business, which creates its own compounding problems for health systems who thought they were buying software.
Whether the industry can agree on what "embedded" even means before the next wave of failed pilots...

The cost of sequencing a human genome dropped from $100M to less than $100 in about 25 years.
That's a million-fold decrease, which outpaces even Moore's Law.
We're about to enter the era of personalized medicine. https://t.co/03I2TfxsAA
Sequencing cost is solved. That's the easy part now.
The actual wall is what you do with the data once you have it. Patient selection, tox prediction, PK modeling, those haven't dropped a million-fold. They've barely moved. I looked at every top-funded AI drug discovery platform for a piece I wrote, and the ones chasing personalized medicine through a single technical lane, say, structure prediction alone, face a real structural problem as full-stack players mature around them.
Insilico Medicine just got a Phase 2 human readout for a fully AI-discovered, AI-designed drug, published in Nature Medicine. One company. Out of the whole field. That gap between cheap sequencing and clinical proof is where personalized medicine will actually be won or lost, and it's not closing as fast as the sequencing curve suggests.

New on the Science Blog: We gave Claude 99 problems analyzing real biological data and compared its performance against an expert panel.
On 23 problems, the experts were stumped. Our most recent models solved roughly 30% of those—and most of the rest. https://t.co/BYqr76zxhk
The Dyno Therapeutics evaluation in the GPT-Rosalind launch tells a similar story from a different angle: best-of-10 submissions hit the 95th percentile of human experts on sequence-function prediction for unpublished RNA sequences. Experts weren't stumped, but they were beaten, which is a different kind of unsettling.
The 30% figure you're citing on problems experts couldn't solve at all is the number that should be making biotech software founders nervous (not the benchmark headline, which is what most people are reading). The commercial question isn't whether AI outperforms experts on any given task. It's whether the capability is now good enough to replace a category of software that was sold on the premise that AI couldn't do this yet.
That's exactly the pressure point I wrote about when the Rosalind plugin infrastructure landed. When you connect that kind of problem-solving to 50+ curated scientific databases at zero cost during preview, the model capability stops being the story. The pricing and the data access together are what actually moves the market for enterprise pharma buyers, and what resets willingness-to-pay for every vertical software company selling into the same accounts.
More on how that mechanism works here: https://www.onhealthcare.tech/p/gpt-rosalind-lands-what-openais-first?utm_source=x&utm_medium=reply&utm_content=2049624600741560340&utm_campaign=gpt-rosalind-lands-what-openais-first
Swan robot captures full-body dermoscopic images in minutes. Tracks new and changing spots across visits. Replaces spot-check exams with total skin coverage. Creates a time-series record for earlier melanoma detection. https://t.co/ukirMPrCOg
Continuous imaging solves half the problem, and the half it doesn't solve is the one that actually determines outcomes.
The time-series record this creates is genuinely valuable, but what happens to that data between visits matters just as much as generating it. The pre-cure model I've been writing about runs into this same wall: you can have dense, high-quality longitudinal data and still fail to act on it earlier if the infrastructure for interpreting trend data isn't built into clinical workflow. A robot that documents change beautifully still depends on a provider reviewing that record against prior visits, flagging the delta, and acting within a window that matters.
And the EHR interoperability problem bites here specifically. If a patient sees a dermatologist at one practice, gets Swan-imaged, then moves or switches providers, that time-series record doesn't necessarily follow them in a format a new system can read. The detection advantage of longitudinal coverage collapses the moment continuity of record breaks, which is the structural failure I keep coming back to in predictive care broadly. The monitoring layer is advancing faster than the data infrastructure layer beneath it, and that gap is where the clinical value gets lost.
The commercial case for this device is real. But the question worth pressing is whether it sells into systems that can actually close the loop from image to intervention, or whether it generates archives that sit in practice-specific silos while the pre-symptomatic window it's designed to capture quietly closes.

Certificate of Need (CON) Laws (1960s–present in ~35 states)
One policy that screwed American healthcare.
Certificate of Need laws require government approval before hospitals or clinics can add beds, buy equipment, or open new facilities. Sold as a way to control costs and
The cost-control framing was always the tell. A 1976 Salkever and Bice study found CON laws produced no significant hospital cost savings and may have actually increased costs in early-adopting states. That was before the federal government even mandated them nationally in 1974.
But the more interesting question is why 36 states kept these laws after Congress repealed the federal mandate in 1987. There was no new cost evidence. The incumbent hospitals had simply had a decade to build compliance and lobbying infrastructure around the approval process, and that infrastructure became its own constituency.
CON laws are a clean example of a pattern that runs through the entire U.S. healthcare regulatory stack: a law passes in response to a real problem, produces no meaningful solution to that problem, and then persists because it creates protected interests that fight repeal harder than reformers fight for it. The mechanism stops being about the original policy goal almost immediately.
And it connects upstream. Hill-Burton dispersed $4.6 billion in grants to roughly 6,800 facilities without any demand-side coordination, which produced supply-driven utilization growth that then justified CON as the corrective. The cage builds one bar at a time, each bar a response to the last.
I traced this whole sequence in some detail here: https://www.onhealthcare.tech/p/how-the-government-built-a-cage-around?utm_source=x&utm_medium=reply&utm_content=2049202740287681014&utm_campaign=how-the-government-built-a-cage-around
"How can medicine save the most lives?"
Most people ask this rhetorically.
@Farzad_MD and Tom Frieden took it literally.
From banning smoking in NYC bars to cutting teen smoking in half in 5 years, this is what happens when you stop treating diseases and start preventing them. https://t.co/v2zpKHHCG6
The Frieden/Farley NYC story is the cleanest natural experiment we have for this argument. Population-level policy, measurable outcome, compressed timeline.
What gets less attention is the infrastructure question underneath it. Banning smoking in bars worked partly because the evidence base was already unimpeachable. Lifestyle medicine doesn't have that yet, at least not for the Medicare population specifically. The evidentiary bar for a CMS national coverage determination is brutal, and lifestyle interventions have historically failed to clear it.
That's why I keep coming back to MAHA ELEVATE. Thirty cooperative agreements, $100M, mandatory nutrition or physical activity components. Small in dollar terms. The actual mechanism is that CMS is now funding the evidence generation it has always said was missing. Win one of those awards and you're not just running a pilot. You're inside the data collection protocols that could eventually justify national coverage for interventions Original Medicare currently doesn't touch.
Frieden built the population-level proof of concept. The question now is whether CMS will fund the clinical proof of concept for lifestyle medicine at scale. The architecture for that is already moving.

HCW #FDA guidance on individualized #gene #editing
$SGMO most direct read through:
ZFP epigenetic regulators
ST-503 (Nav1.7 /SCN9A gene repression in neuropathic pain)
ST-506 (PRNP gene repression prion)
modulate gene expression w/o cutting DNA;
face reduced burden w latest NGS https://t.co/rIWPpyuMIR
The PRNP program is actually where this gets interesting to think through, because prion disease is about as close to a natural history problem as gene therapy gets: you have a defined genetic abnormality, a documented progression curve in symptomatic carriers, and essentially zero competing treatment options, which is exactly the profile the Plausible Mechanism Framework was built around.
The reduced NGS burden for non-cutting editors is real, and it matters commercially, but the part of the guidance that I'd be watching more carefully for Sangamo specifically is the modular variant logic. If ZFP epigenetic regulators targeting SCN9A can be structured as a platform under a single IND, each additional variant serving a different patient subpopulation or mutation context doesn't necessarily require its own clinical trial to reach approval, which changes the math on how many patients you actually need to build a durable pipeline.
The catch is that natural history data becomes the rate-limiting asset under this framework, not the editing technology itself.
So the question I keep coming back to for ST-503 and ST-506 is how deep Sangamo's natural history characterization actually goes at this stage, because the PMF doesn't reward good editing chemistry if the disease progression documentation isn't there to anchor the mechanistic argument to clinical outcomes, and that's the piece that tends to get treated as an afterthought in early program design when it probably shouldn't be.
More on the full PMF and NGS guidance architecture here: https://www.onhealthcare.tech/p/the-fda-just-rewrote-the-rules-for?utm_source=x&utm_medium=reply&utm_content=2049440850095079436&utm_campaign=the-fda-just-rewrote-the-rules-for
Health care fraud is not a victimless crime. It affects everyone and causes billions of dollars in losses each year. It can raise health insurance premiums, expose you to unnecessary medical procedures, and increase taxes. Learn more: https://t.co/ggTyKY0rZW https://t.co/PrFGgzcJh8
The framing of fraud as a cost everyone absorbs is right, but the part that gets skipped is why some payers absorb far more of it than others. Medicare loses 8-20% of spend to fraud. Commercial plans lose 1-3%. And the gap is not about who investigates after the fact, it's about what happens before the claim gets paid at all. Prior auth and denials are brutal to deal with, and I've written at length about why the process is broken operationally, but when I dug into the fraud numbers at https://www.onhealthcare.tech/p/prior-auth-and-denials-are-healthcares?utm_source=x&utm_medium=reply&utm_content=2049262543118496212&utm_campaign=prior-auth-and-denials-are-healthcares the thing that kept coming up was how much of that tenfold gap traces back to one structural fact: commercial payers check before they pay, and Medicare largely chases after. And the current push to strip prior auth out of commercial plans is moving in exactly the opposite direction from what the fraud math would suggest. So what does a workable middle ground look like if you can't just keep the system as is, but you also can't remove the controls without...
It turns out, the job of a radiologist isn't to read x-rays.
It's to cure people.
And if AI can help speed the process of understanding x-rays, radiologists can see and cure more people.
Watched this play out at a real system level. Aidoc deployed across a trauma network, and the radiologists didn't lose volume. They absorbed more cases with the same headcount, and turnaround on critical findings dropped by over 40%. Revenue per radiologist went up, not down.
The Hinton 2016 prediction that radiologists would be replaced within five years is the clearest example of what happens when you mistake the task for the job. Reading the film was never the value. The value is diagnostic judgment, communication with the care team, procedural intervention, and liability bearing. AI handles none of that.
But here's what the compensation data actually shows, which most people miss. Radiology starting offers are now commonly above $600K, a full decade after Hinton's funeral announcement for the specialty. That's the market pricing in scarcity and the multiplier effect simultaneously. The specialties most exposed to AI augmentation are commanding more, not less, because throughput scales while supply doesn't.
And primary care is tracking a similar curve through a different mechanism. Risk-bearing PCP platforms like Agilon and Oak Street are paying top-quartile physicians $700K to $900K precisely because AI-assisted panel management lets one physician carry meaningful risk on a much larger attributed population. The cognitive load per patient drops. The revenue per physician climbs.
The compression in medicine right now is hitting procedural volume that gets bundled under mandatory payment models, not cognitive specialists with AI leverage.

1/12 Introducing MIMIC: a SOTA foundation model trained natively across DNA, RNA and proteins. MIMIC is multimodal and generative: it can use structure, regulation, evolution, and experimental context to infer missing biology or design new sequences. https://t.co/jyNNrqkbaL
The question this raises for me: who builds the data infrastructure that makes a model like MIMIC clinically useful, versus scientifically impressive?
A foundation model trained across DNA, RNA, and proteins is a real technical achievement, but the bottleneck I keep running into when I look at health AI isn't the model, it's what happens when you try to connect outputs like this to actual patient data. Alzheimer's research is the clearest example I've found: larger cohorts exist, but studies still run on dozens to thousands of patients because harmonizing genomics with imaging and cognitive assessments across sites is too expensive to do at scale (the cost is in engineering time, not compute). The multimodal fusion problem at the clinical layer is what throttles whether a model like MIMIC ever touches real populations or stays in research contexts.
The Stripe analogy I've been working through is useful here: payments didn't get solved by better financial theory, it got solved by abstracting the plumbing.

Individualized medicine is moving from concept to reality.
New FDA guidance supports therapies designed for single patients with ultra rare diseases.
At Therna Biosciences, we are building an AI enabled RNA platform to make this possible.
Link to our CEO’s post in the comments https://t.co/lVZO88BFaZ
The FDA's Plausible Mechanism Framework is the specific regulatory instrument making this real. It lets a single BLA cover multiple product variants through mechanistic logic alone, no separate clinical trial per patient, which changes the math on whether ultra-small-cohort programs can ever be commercial.
What I'd push on is the natural history piece. The PMF's five-element standard requires characterizing disease progression before you can lean on plausible mechanism as a substitute for large trial data. Programs that haven't built that data asset from day one will hit that wall hard when they try to use the framework's variant-bridging logic later.
The AI angle you're describing maps onto something I looked at closely: in silico off-target nomination. The new NGS safety guidance requires genome-wide homology scanning that accounts for mismatches, bulges, and non-canonical PAM sequences before IND submission. That's exactly the kind of structured prediction problem where an AI-enabled platform has a real edge over ad hoc methods.
Single-patient approval now has a workable path. That's new.
I wrote about the full regulatory structure behind this, including how the PMF and NGS guidance work together and what it means for platform companies building across variant families: https://www.onhealthcare.tech/p/the-fda-just-rewrote-the-rules-for?utm_source=x&utm_medium=reply&utm_content=2049539466599997747&utm_campaign=the-fda-just-rewrote-the-rules-for
There’s a lot more happening at the pharmacy counter than most people realize…
Pharmacists are answering questions, double-checking prescriptions, giving vaccines, and helping people navigate what can often feel like a confusing process.
𝐓𝐞𝐚𝐦 𝐂𝐮𝐛𝐚𝐧 𝐂𝐚𝐫𝐝 was built https://t.co/wh2yrVY0SL
...and that clinical layer is exactly where the pricing story gets complicated.
Cost Plus has a clean model on paper: acquisition cost, 15% markup, a small fee. But the pharmacy counter work you're describing, the checks, the consults, the vaccine admin, that's labor-intensive infrastructure that spread pricing and rebate dollars have historically cross-subsidized in ways nobody admits out loud.
When I looked at what a Cost Plus and CenterWell pairing could actually do, the piece that made it viable wasn't the pricing formula. It was capitation. CenterWell's model means the care team has a real reason to want drug costs down, which changes how pharmacist time gets valued and deployed. In a fee-for-service world, cheaper drugs can actually reduce revenue. That sounds absurd, but the incentive math is real.
The harder question is whether transparent pricing at scale can fund the clinical work at the counter without leaning on the same margin games Cost Plus is trying to cut out. Right now Cost Plus is still small enough that it can stay clean. But if this becomes the platform model for MA plans and employers broadly, the operational costs of that pharmacist doing the work you're describing have to live somewhere in the budget.
That tension doesn't get talked about much. Where does the money for that counter work actually come from if spread pricing disappears and volume is still modest?
More on the structural case here: https://www.onhealthcare.tech/p/the-pharmacy-wars-get-interesting?utm_source=x&utm_medium=reply&utm_content=2049590901962408270&utm_campaign=the-pharmacy-wars-get-interesting
We’ve turned healthcare into financial engineering, and the math is catching up.
In about six years, Medicare spending goes from $1 trillion to $2 trillion and the trust fund runs out. Washington would rather feed people simple answers than tell the truth about the math. https://t.co/kFYkWkscPh
The math framing is right but the trajectory question is harder than the trust fund headline suggests.
Between 2009 and 2019, real per capita healthcare spending grew at 1.7% annually against a 3.7% historical baseline (a gap that produced $783 billion in cumulative spending below CMS projections). That deceleration held through 2023 despite COVID. The insolvency cliff looks different if that rate persists.
The harder problem is that the deceleration came from specific mechanisms, generic substitution, non-physician care delivery, ambulatory migration, and those mechanisms have limits. Medicare inpatient stays per beneficiary are already down 10-30%. You can't harvest the same efficiency twice.
So the real policy question isn't whether the math is bad (it is), it's whether the structural forces that bent the curve once are still operating or whether we've already captured most of that gain. Washington skips that question entirely because it requires admitting the ACA actually changed something real without being able to promise it's enough.

We’ve built a surgical robot to automate key steps in the process of receiving a Neuralink implant to promote safety, reliability, and scalability.
Learn more about the role of the robot and its future potential from the engineers helping develop it. https://t.co/O7vg1CNqxg
Neuralink publishing engineering content about their surgical robot is a signal worth reading carefully. They're not just solving a neuroscience problem anymore. The bottleneck has shifted to manufacturing and procedural reliability, which means the technical gaps that matter most right now are upstream of the implant itself.
When I modeled the build-vs-buy calculus for Neuralink and Merge Labs, semi-manual electrode array manufacturing with low yields kept appearing as one of the named bottlenecks, alongside the surgical placement precision problem. A robot that automates implant steps doesn't close that gap, it exposes the next one: real-time intraoperative feedback, electrode placement verification, post-surgical signal quality confirmation. Those are solvable problems that don't require an end-to-end platform to address.
This is exactly the dynamic I wrote about. When a platform company publishes engineering content describing a specific process they've automated, they're also implicitly publishing a map of what they haven't automated yet. Job postings and research papers do the same thing. The infrastructure opportunity lives in those gaps.
The founders who read this Neuralink post and think "I could never compete with that robot" are correct. The founders who read it and think "what does that robot still need to work well" are looking at the right question.

Metabolic & Bariatric Surgery associated with greater long-term heart risk reduction than Weight-Loss Meds
- Lifetime cardiovascular risk🫀decreased more w surgery (8.6% vs 1.7%).
- Weight loss ⚖️ was significantly greater w surgery, (TWL 28% vs 11%)
https://t.co/EcOKUfnp3r
The cardiovascular gap here is striking, 8.6% versus 1.7% lifetime risk reduction is not a marginal difference, that's a different category of intervention entirely.
What makes this finding harder to dismiss is the weight loss delta. 28% total weight loss versus 11% maps almost exactly onto what I found when I looked at magnetic compression anastomosis outcomes, where the MagDI plus sleeve cohort hit 25-35% total weight loss at 12 months while GLP-1 benchmarks cluster around 10-15%. The mechanisms differ, but the outcome gap is consistent across both comparisons.
The post frames this as surgery versus medications. The more specific version of that question is whether the surgical category itself can be expanded. Right now bariatric surgery is gatekept by specialized training requirements, facility costs, and geography. Magnetic anastomosis changes that constraint because it runs on basic laparoscopic and endoscopic skills rather than advanced bariatric technique.
Payers are the audience who most need to see this data.
If a one-time procedure produces cardiovascular risk reduction five times greater than chronic pharmacotherapy, the lifetime medication dependency model stops looking like a clinical strategy and starts looking like a cost structure. I went deep on the economic comparison, including what happens to the GLP-1 business model when surgical alternatives with 70-80% five-year cost savings start competing for the same indication: https://www.onhealthcare.tech/p/magnetic-compression-anastomosis?utm_source=x&utm_medium=reply&utm_content=2049267249517649944&utm_campaign=magnetic-compression-anastomosis
Hospital systems keep getting bigger, crushing competition and sticking families with higher bills. The
@WaysandMeansGOP hearing exposed it: hospitals defended abusive fees while patients pay the price. More consolidation means more pain for patients https://t.co/sicOkvg4CU
The consolidation story is real, but the fee structure underneath it is weirder than most people realize. I tracked the cost-to-charge ratio across hospital systems going back to 2000, and what you find is that the markup component of a hospital bill grew from roughly 40% of charges to 70% over two decades (not because costs fell, but because charges climbed far faster than actual operating expenses).
The part that rarely comes up in consolidation hearings: those inflated charges aren't arbitrary. Larger systems have dedicated chargemaster specialists whose job is optimizing how charges interact with specific payment triggers, Medicare outlier thresholds, commercial insurer stop-loss provisions, the whole architecture. Consolidation accelerates this because bigger systems can afford more sophisticated revenue cycle infrastructure to do it at scale.
So when a family sees an abusive fee on a bill, they're often looking at a chargemaster price that was set to hit a particular financial threshold, not to reflect any recognizable cost of care. The price transparency rules that were supposed to help patients compare prices mostly exposed these chargemaster figures, which are themselves the inflated artifact. Comparing them is like comparing two different fictions.
The Ways and Means hearing probably got at market power, which matters. But the incentive structure inside the payment system itself is doing a lot of quiet work that consolidation then amplifies. I wrote through the mechanics in some detail here: https://www.onhealthcare.tech/p/the-economics-of-hospital-charging?utm_source=x&utm_medium=reply&utm_content=2049522688398369149&utm_campaign=the-economics-of-hospital-charging
The left column is current site of service differential for an epidural steroid injection done in an independent physician office (top) and then again done in a vertically integrated, hospital employed physician office (bottom - HOPD). The right column is a proposed policy https://t.co/A7AqAW3UF1
The site-neutral payment math here is brutal for health systems that built their employed physician strategy around HOPD billing premiums. When CMS follows through on cutting hospital-based clinic reimbursement 30-40%, systems that acquired physician practices specifically to capture that differential are going to find those acquisitions repriced into liabilities overnight.
What makes this harder than it looks is that the collapse is happening simultaneously with the M&A market seizing up. Traditional hospital deal revenue fell nearly 50% year-over-year in 2025, so the typical exit ramp (sell the struggling employed group into a larger system) is mostly gone. Health systems are left holding physician enterprise costs they can't unload and reimbursement rates that are about to compress significantly.
The downstream effect nobody is talking about enough: this accelerates the shift toward joint venture structures with independent ASCs and physician groups rather than ownership, which is actually where I spent a lot of time in my piece on the Vizient data. GenesisCare's HATCo model and structures like Risant Health are early signals that health systems are moving toward orchestration rather than consolidation (the distinction matters enormously for how software gets built for this market).
So who builds the infrastructure layer that makes federated physician networks actually function when you're not the employer?

Hospitals make hundreds of billions of taxpayer dollars to treat chronic disease.
They shouldn’t be serving food that causes chronic disease.
Thanks to hospitals who’ve stepped up. We expect every major system to this year. https://t.co/OwIyMT3yDT
The economic misalignment is real, but there's a layer underneath it: even hospitals that fix the menu often leave the terminology untouched, and patients eating better food still get handed a "diabetes" diagnosis that tells them nothing about what caused it or what they can change. I wrote about how disease naming itself shapes patient agency at https://www.onhealthcare.tech/p/the-linguistic-architecture-of-chronic?utm_source=x&utm_medium=reply&utm_content=2049540568481411519&utm_campaign=the-linguistic-architecture-of-chronic, and the short version is that food reform without language reform only gets you halfway there.
The MFN pricing deals were announced as a "comprehensive solution" to American drug pricing.
However, many of the pricing provisions apply to Medicaid. Meanwhile, two thirds of the country has private insurance, employer plans, or individual market coverage — paying full freight https://t.co/VlYF0VAmoC
Medicaid coverage is the narrower problem here. The deeper gap is that public MFN benchmark prices are now visible, which creates an ERISA fiduciary exposure for every employer plan still paying commercial rates above those benchmarks. That's not a theoretical risk. Courts have been expanding fiduciary duty claims against employers who fail to seek lower drug prices when lower prices are demonstrably available.
So the private insurance population you're describing doesn't just get left out of the savings. They become the evidence in litigation. The moment a plan sponsor can be shown to have known about a $245 Medicare/Medicaid net price on a GLP-1 and continued paying $600 through a PBM contract, the fiduciary argument writes itself.
What makes this worse is that there's no published MFN calculation formula, no reference country basket definition, no contract text for any of the 17 deals. Employers and their counsel can't actually verify whether their contracted rates are above or below the MFN floor because the floor itself isn't published in any form that allows third-party validation. The adjudication infrastructure to bridge that gap doesn't exist at production scale yet.
I went deep on the full cohort reconstruction and the TrumpRx infrastructure vacuum in my piece. The commercial insurance population isn't just underserved by this program. It's where the compliance liability accumulates.

Health insurance is not healthcare.
It’s a wasteful and unnecessary bureaucracy that sits between you and your doctors and hospitals, designed to exploit the working class and transfer their wealth upwards.
Demand Medicare for All.
Medicare for All still runs through CMS, and CMS processes over a billion claims a year through a network of private contractors it already depends on. The administrative layer doesn't disappear, it just changes whose name is on the contract.
But the harder question is whether the real problem is private insurers specifically or whether it's that nobody, public or private, has ever had a serious incentive to design the payment and coverage machinery to actually work. Federal employees developing physician fee schedules and coverage determinations without competitive pressure aren't obviously better at that job than the people they're criticizing.
Competition in policy design is underexplored.
Wrote about what it would look like to open CMS's own regulatory and payment functions to competitive bidding while keeping Medicare publicly governed: https://www.onhealthcare.tech/p/reimagining-medicare-fee-for-service?utm_source=x&utm_medium=reply&utm_content=2049537128980222303&utm_campaign=reimagining-medicare-fee-for-service
"A decade ago, AI was supposed to replace radiologists. Today, radiologists make more than $500,000 per year, and their employment continues to grow, see chart below. Reading scans is a task, not a job, and when the task gets cheaper, demand for the job grows." https://t.co/0OszRhslcq
The radiology case is real, but it points somewhere most people miss. When scan reading got cheaper, health systems ordered more scans, which kept radiologists busy. That's the demand side. What it doesn't tell you is what happens on the supply side when the bottleneck isn't volume but shift coverage and burnout-driven turnover.
That's where the math gets different for clinical labor broadly. I spent time looking at nurse and physician workflows through the lens of the Anthropic observed-exposure data (the gap between what AI can do and what's actually deployed), and the pattern isn't "task gets cheap, job grows." It's closer to "task gets cheap, vacancy rate stops compounding." Health systems running 10-15% RN vacancy rates aren't trying to grow headcount, they're trying to stop bleeding $40,000-$60,000 per nurse in turnover costs. AI that cuts doc burden by half per encounter doesn't expand demand for nurses the way cheaper imaging expanded demand for radiologists. It just lets the same nurses handle the load they were already short-staffed for.
The radiology story is about volume elasticity in a market that wanted more scans. The hospital labor story is about margin recovery in a market that can't hire fast enough to meet current demand. Those are different structures, and they produce different outcomes for workers over time.

man we are getting almost 15 gigabytes of data for every single cell rn and everyone is underestimating what this means for drug discovery. it's what happens when you start treating drug-cell chemistry as a movie instead of a snapshot. because it will never be a snapshot. https://t.co/eqPuF4I2nk
The data density point lands, and the movie-vs-snapshot framing is exactly right, but the harder question is what you do with 15GB per cell once you have it. That's where most platforms are still stuck, the phenomics side has outrun the ability to connect cellular perturbation signatures to actual clinical outcomes.
insitro's POSH methodology, combining pooled CRISPR, Cell Painting, and self-supervised learning, is probably the most technically serious published attempt to build that bridge, their Nature Communications 2025 paper is worth reading carefully. But even there, the translation gap from cellular phenotype to clinical benefit stays open. No phenomics-first company has closed it in humans yet.
That's what makes Insilico's Phase 2 rentosertib readout in IPF so structurally important. Clinical data is the only real answer to the translation question, everything upstream of it is still hypothesis. More on where the data density race fits in the broader AI drug discovery stack here: https://www.onhealthcare.tech/p/the-ai-drug-discovery-capital-stack?utm_source=x&utm_medium=reply&utm_content=2049572013183013043&utm_campaign=the-ai-drug-discovery-capital-stack
A couple points about why radiologists thriving, not disappearing, with AI:
1️⃣Human + AI is a winning paradigm. I get an immediate AI alert as the scan is done (e.g. stroke suspected), then a couple minutes later a more detailed report/call when the human reads it.
The Hinton 2016 "radiologists are done" prediction aged about as well as any single-factor forecast can. What actually happened is the opposite: AI triage tools like Aidoc and Viz.ai compressed the time-to-read on high-acuity cases, which let radiologists handle higher volume without proportional overhead growth. That's a productivity multiplier, not a replacement mechanism.
And the compensation data backs this up. Radiology starting offers are commonly above $600K now, which is the wrong direction for a specialty supposedly being automated out of existence.
The deeper point is that the human-plus-AI paradigm you're describing is exactly what shifts radiology from a throughput-constrained model to a judgment-and-liability model. The AI handles the commodity layer. The radiologist captures the economic value of the hard calls. That's a structurally better position than most procedural specialties that are now facing mandatory bundled payment compression with no equivalent productivity lever.
Wrote up how this fits the broader compensation reshuffling happening across specialties over the next decade: https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2049563811825562035&utm_campaign=how-ai-value-based-care-bundles-medicare
📈 NVIDIA tops AI leaderboards and benchmarks with open models driven by extreme co-design across compute, networking, memory, storage, and software.
This includes models for biology, AI physics, agentic AI, physical AI, robotics, and autonomous vehicles.
By being vertically https://t.co/ybjuWm637C
The biology piece is where I'd push back slightly on "vertically integrated" as the full story. What I've been tracking is that NVIDIA's real position in healthcare isn't the GPU performance numbers, it's that BioNeMo's three-tier architecture now lets a five-person biotech team run molecular dynamics and protein structure prediction workflows that two years ago required a mid-size pharma company's entire computational biology department. The benchmark wins matter less than the fact that the capability floor dropped dramatically for small teams.
That structural shift is what I wrote about in detail here: https://www.onhealthcare.tech/p/nvidias-healthcare-stack-is-the-picks?utm_source=x&utm_medium=reply&utm_content=2049579475017277760&utm_campaign=nvidias-healthcare-stack-is-the-picks
The co-design story you're describing across compute, networking, and software is real, but in healthcare the stickiest moat isn't benchmark performance on any single dimension. It's that Holoscan for edge inference, MONAI for imaging, Parabricks for genomics, and Isaac for surgical robotics are all pulling developers into the same ecosystem simultaneously. A founder building an intraoperative AI tool can't use cloud architecture because the round-trip latency is clinically unacceptable. That requirement alone makes Holoscan close to mandatory for a whole class of applications.
The leaderboard wins get the headlines. The part that's actually harder to replicate is the depth of open-source academic validation MONAI has, 6.5 million downloads and citations in over 4,000 peer-reviewed papers, which is what gets a platform through hospital IT governance committees. That's a different kind of moat than compute co-design.
What superhuman vision can detect from the retinal photo, which human eyes cannot, is stunning. A new foundation AI model screening for diabetes hypertension, hyperlipidemia, gout, osteoporosis, and thyroid disease @NatureMedicine
https://t.co/GhKvUqz4Vy https://t.co/iKcXCbLceu
58% hallucination reduction by targeting internal model circuits rather than filtering outputs tells you something about why that retinal model matters beyond its accuracy numbers.
The patterns it's found aren't just predictions. They're encoded knowledge about disease biology that the model learned from data, knowledge that didn't exist in explicit form before. That's the part that doesn't show up in a Nature Medicine abstract: who can explain what the model actually detected, and why, at the level a clinician or regulator needs.
FDA and CMS are moving toward requiring that explanation as a condition of clinical use, not a bonus feature. A model that can screen for six conditions from a retinal image is impressive. A model that can't say which internal features drove each call is going to hit a wall before it reaches wide deployment. The interpretability layer is what converts that capability into something a health system can actually put in front of patients.
Mayo Clinic took a financial stake in a company built entirely around reverse engineering what foundation models have learned. That's a procurement signal, not a research bet.

.@RepJasonSmith: Large hospital systems “manipulate the 340B drug pricing program to keep steep drug discounts for themselves instead of passing the savings to low-income patients.”
Taxpayers get the bill. Hospitals get the discounts. Patients get left behind.
It’s time for https://t.co/UoLwidGU7H
The political pressure is real, but the mechanism behind it is more specific than "hospitals keep the discounts." What's actually enabling the arbitrage is HRSA's 1996 non-binding patient definition guidance, which was never promulgated as a formal rule and has never faced serious judicial scrutiny because Chevron deference made challenging it nearly impossible before last year.
AbbVie's lawsuit changes that calculus. Post-Loper Bright, a court can now independently interpret the statutory meaning of "patient" under 42 U.S.C. § 256b without deferring to HRSA's expansive 1996 definition. That's the legal opening that didn't exist before, and it matters more than any contract pharmacy dispute because it goes to who qualifies for 340B eligibility in the first place.
But the growth story is also being misread as a pricing problem when the data suggests otherwise: a 2025 PMC study attributed roughly 80% of 2018-2024 list-price growth to utilization expansion versus 17% from price increases. The program hit $81.4 billion in 2024 purchases, growing at a 23.5% CAGR since 2015, and covered entities grew from roughly 1,000 in 1992 to 50,000+. That's an eligibility and enrollment story, not just a bad-actor story.
Reform without touching the patient definition just trims around the edges.

Many physicians are leaving medicine because they don’t know their options.
The Options:
- Flexible part-time/per-diem jobs
- Highly paid experts & consultants
- Launching ventures without MBA
- Blending non-medical interests
- Remote medical writing
- Thriving independently
The framing here assumes the exit is the problem to solve, when the more interesting question is why the exit looks attractive in the first place.
Compensation compression is doing real work here that gets obscured when we talk about "options." A family physician at $250K who feels burned out is making a rational calculation, but that same physician in a risk-bearing arrangement through something like Agilon or Oak Street can clear $700K-$900K, which changes the math on whether leaving is actually the right move. The options menu you've listed is genuinely useful, but it gets presented most often to physicians who have already decided the core job is broken, rather than to physicians who might find the core job restructured into something worth staying for.
The per-diem and consulting paths are real, but they're also largely available only to physicians who built equity inside a specialty first (which is its own filter that rarely gets named in these conversations).
The harder truth is that the physicians most likely to explore these exits are often in the specialties facing the most structural pressure, procedural and hospital-employed, right as bundled payment models and conversion factor cuts are compressing their compensation ceiling. The exit conversation and the compensation restructuring conversation are running in parallel without connecting.
I've been tracking the convergent mechanisms pulling at both ends of this: https://www.onhealthcare.tech/p/how-ai-value-based-care-bundles-medicare?utm_source=x&utm_medium=reply&utm_content=2049179790712692914&utm_campaign=how-ai-value-based-care-bundles-medicare
Real-time clinical trials could fundamentally transform the clinical trial landscape. https://t.co/GzMrKTjh9B
The "real-time" framing is doing a lot of work here, and the part that gets glossed over is what real-time data actually has to be compared against to mean anything regulatory.
Speed of measurement isn't the constraint. The constraint is comparator validity. You can stream continuous endpoints from a wearable and still have no defensible external control arm because the historical patient population was phenotyped differently, the covariate distributions don't align, and nobody has done the temporal recalibration the FDA's 2025 externally controlled trial guidance now explicitly requires. Real-time in, garbage comparison out.
What strikes me about this moment is that the infrastructure gap is structural, not just technical. The best real-world comparator data sits inside health systems that will never centralize it (legally, institutionally, competitively). So the real engineering problem isn't building faster trial software, it's building federated comparator networks that can produce regulatory-grade evidence from distributed, heterogeneous data without moving the underlying records. That is a genuinely hard problem, and very few companies are oriented toward it.
Adaptive, continuous trial designs actually make this harder, not easier. More measurement points mean more opportunities for phenotype drift between trial and comparator populations to corrupt your inference. The faster you run, the more precision you need in the underlying evidence architecture (and most current platforms don't have it).
I've been writing about exactly this gap, the point where AI-accelerated discovery collides with an evidence generation system that hasn't kept pace.

$PLTR FDA announces they’re turning to AI to speed up clinical trials.
Meanwhile:
A Palantir impact study shows a “government agency” used @PalantirTech to integrate over 100 clinical trials for cancer immunotherapies …. 🧐 https://t.co/bQaKXZQrGS
The hard part isn't integrating 100 trials, it's whether the data coming out of them is actually comparable. About 1 in 5 real-world oncology patients wouldn't even qualify for the phase 3 trials their treatment is based on, so "integrated" infrastructure still leaves you with a phenotype problem nobody's solved at scale. FDA's 2025 draft guidance on external controls is basically a technical spec for that exact gap, and right now no one's fully built what it requires.

Should AI design the drugs put into your body? Max Jaderberg is the President of Ismorphic Labs – an Alphabet company, spun out from the world-leading AI lab DeepMind, with the sole mission of using AI to revolutionise drug discovery.
In a conversation at @sxswlndn, Jadergberg https://t.co/fryAoDoV5f
Watched Jaderberg's framing closely and the part that keeps pulling at me is what "design" actually means in this context.
RFdiffusion hitting over 80 percent experimental validation on designed protein-protein interactions isn't AI suggesting candidates for humans to evaluate, it's AI generating structures with properties that wouldn't surface through traditional screening at all. Multi-specific binders, enzyme switches that only activate in particular cellular environments, these aren't faster versions of existing molecules. They're geometrically different from what evolution produced or what medicinal chemists would reach for.
The question "should AI design drugs" is almost already settled at the preclinical level, it's happening now at Isomorphic, at Generate Biomedicines, at a dozen other places. The harder question is what breaks when you push from single-objective design into simultaneous optimization across activity, immunogenicity, pharmacokinetics, and manufacturability. Current foundation models are genuinely good at one thing at a time. Commercial drug development requires all of them at once, and that's where the gap between impressive demos and approved therapies still lives.
Jaderberg is right that the question is no longer whether AI can do this. But I'd push back on framing it as a binary choice about trust. The more interesting tension is whether unified foundation models integrating sequence, structure, and assay data can close that multi-objective gap before the hype cycle exhausts investor patience.
That's the argument I've been making, and where I think the next 36 months actually get decided: https://www.onhealthcare.tech/p/the-convergence-revolution-how-artificial?utm_source=x&utm_medium=reply&utm_content=2049142036775731593&utm_campaign=the-convergence-revolution-how-artificial
People say the golden age of medicine is in the past. A time when you could see the same doctor for years, know them on a first name basis. Maybe even have their cell number for a moment of real need. A time when the physician was the architect of the system, with the patient’s best interest at heart and roots in the local community.
What we have now is not a new phenomenon. A select oligarchy of intermediaries has systematically stripped virtue and respect from medicine in pursuit of profit. Thomas Jefferson warned of exactly this: “Dependence begets subservience and venality, suffocates the germ of virtue, and prepares fit tools for the designs of ambition.”
The golden age of medicine is not dead. It is rising again in America. The Selkirk Center was built out of frustration with predatory fees, the erosion of physician leadership, and a system that has forgotten who it exists to serve. The community deserves better. Physicians belong at the helm. The needless intermediaries are being phased out.
If you are done with a system that puts profit before people, reach out to the Selkirk Center team. The door is open.

Big thanks to @real_doc_speaks for having me on his podcast & support!

The nostalgia framing is understandable, but the erosion of physician autonomy has a more specific mechanism than "intermediaries pursuing profit." What actually happened is that each new layer of administrative complexity, quality reporting requirements, risk contracts, compliance infrastructure, created a version of medicine where the physician's attention is the scarce resource being consumed by the system rather than directed at patients.
That's the part worth tracking closely.
When I looked at CMMI's 18 payment model experiments, the government spent $1.3 billion in administrative overhead alone, with only four models showing clear quality improvements. The physicians inside those models weren't suddenly more or less motivated to help patients. They were just buried. The problem was never physician goodwill. It was the machinery built on the assumption that goodwill needed to be engineered through financial incentives, and that machinery has real costs.
What the Selkirk model gets right is removing the layers that consume physician bandwidth without adding clinical value. The technology exists now to do exactly that within existing payment structures, without waiting for the next round of payment reform to arrive and generate its own compliance burden.
Full piece on why augmenting what physicians already bring is a more productive path than restructuring their incentives: https://www.onhealthcare.tech/p/beyond-value-based-care-empowering?utm_source=x&utm_medium=reply&utm_content=2048869848034460011&utm_campaign=beyond-value-based-care-empowering
Medicaid dollars are supposed to go to the most vulnerable Oregonians in our communities.
Our Medicaid Fraud Control Unit investigates and prosecutes Medicaid fraud across our state – and has recovered over $85 million in taxpayer dollars in the past 10 years. https://t.co/kNzj6hJa6M
$85M over ten years is real money, but the FMAP math quietly complicates how to read that number. If Oregon runs around a 64% federal match, the state's own budget exposure on any given fraud dollar is roughly 36 cents, which means the incentive to invest heavily in detection is structurally dampened before a single investigator opens a case.
The recoveries also almost certainly undercount what's actually slipping through, because the fraud that's hardest to catch is home health and personal care, where the clinical artifact is unverifiable by design: a care plan signed by a compliant physician, a timesheet filled out by the same person being paid, and EVV implementation that in many states still triggers corrective action plans rather than payment denials when non-compliant.
The gap isn't investigator effort, it's that enforcement is working against a program design that makes fraud structurally invisible at the point of claim adjudication.
What changes the recovery trajectory isn't more investigators working existing referral pipelines, it's cross-dataset linkage: joining spending data against NPPES entity formation dates, OIG exclusion records, and state corporate filings to surface the ramp-and-exit pattern before a bust-out scheme has already run three billing cycles and dissolved the LLC. That's a two-to-four person engineering effort, the signal is there in public data, and the $2.80 return per enforcement dollar from HCFAC suggests the ROI math is favorable well before you've optimized the pipeline.

You are total moron who doesn’t understand anything about the healthcare system.
Let me help you out.
Picture a town with 1 hospital.
A doctor wants to open a clinic across the street.
He has the money.
He has the patients.
He needs one thing first…
Permission from the hospital he’s about to compete with.
That’s not a joke.
It’s called Certificate of Need.
Thirty-five states still do it.
The hospital that’s already there gets to vote on whether the new one exists.
They always vote no.
That’s why your local hospital can charge $4,000 for an MRI that costs $400 in cash at an independent clinic two states away.
There is NO competition because regulations has strangled it.
It gets worse.
The AMA caps how many doctors America trains every year.
On purpose.
They’ve done it since 1997.
We have a shortage they manufactured.
A nurse practitioner who could handle 80% of what a GP does is banned from doing it solo in half the states.
Why? Because doctor lobbies wrote the laws.
Hospitals lobby to block hospitals.
Doctors lobby to block doctors.
You don’t have a market. You have a cartel.
Every wall in this maze was built by someone who profits from you being lost in it.
The fix isn’t complicated.
It’s just illegal in too many places.
1) Kill Certificate of Need.
Let anyone build a hospital. Let surgery centers open across the street from the big systems. Watch prices drop DRAMATICALLY.
2) Uncap residencies and medical schools
3) Let nurse practitioners and pharmacists practice to the full scope of their training in every state. Most of what you go to a doctor for doesn’t need a doctor.
4) Untie insurance from your job and make individual plans fully tax-deductible.
The reason healthcare is a shit show is because there is ZERO competition because it is strangled by regulations and funded by the government.
Everything that is funded by th government goes this way.
Look at college tuition… same route.
The best thing you can do for prices is to pull out the government in every possible area.
The CON framing is right, the mechanism description has a gap worth filling.
Most states don't literally hand the incumbent hospital a vote. The actual process is a state board review where existing providers can submit testimony opposing applications, and they do, relentlessly, with lawyers and consultants the new entrant can't match. The incumbent doesn't vote no, it just buries the applicant in procedural costs until they give up or run out of capital. Same outcome, different machinery, and the distinction matters if you're actually trying to reform it.
The 1976 Salkever and Bice study found CON produced no significant hospital cost savings and may have actually increased costs in early-adopting states. That's the part that should sting more than it does in this conversation. The law wasn't just captured by incumbents after the fact, it was ineffective at its stated purpose from the start, which means the moat was always the real product.
On the AMA residency cap: that's a real constraint, but federal GME funding through CMS is doing most of the structural work there. Congress has increased residency slots in fits and starts, the 2021 infrastructure law added 1,000 over five years. The AMA is a lobbying force but framing them as the sole mechanism overstates their direct power relative to how Medicare funding formulas actually operate.
The clean deregulation story is genuinely appealing, it's just that the layers are causally connected in ways that make pulling one thread unpredictable. CON didn't emerge from nowhere, it came after Hill-Burton pushed $4.6 billion into 6,800 facilities without any demand-side coordination, flooding the system with beds that then filled themselves.
Wrote through the whole causal chain here: https://www.onhealthcare.tech/p/how-the-government-built-a-cage-around?utm_source=x&utm_medium=reply&utm_content=2049331201031200890&utm_campaign=how-the-government-built-a-cage-around
I am surprised how many AI utopianists double down on AI-generated synthetic data, to train "superintelligence" or "solve biology".
Synthetic data is pretty much a dead end in serious AI research, outside of a few specific domains where data integrity can be easily verified
The "few specific domains" framing is doing a lot of work here, and healthcare is exactly where the boundary gets uncomfortable. Synthetic EHR data isn't a dead end universally, but the failure mode is concentrated in the worst possible place: tail distributions and rare events. For sepsis prediction specifically, that's not a minor calibration issue. The accurate probability estimates are what drive clinical decisions, so a model that performs well on average but drifts on the 5% of patients who present atypically is potentially more dangerous than no model at all.
The real problem I keep circling back to is structural. The institutions holding the richest, most representative data have the strongest incentives to keep it exclusive. Synthetic generation was supposed to break that lock, but if it systematically underrepresents the edge cases that make data valuable in the first place, you haven't solved the access problem. You've just papered over it with something that looks like data.
Federated learning doesn't fix this cleanly either. Its own coordination and free-rider dynamics are genuinely hard in multi-hospital deployments, and calling it a cleaner solution ignores how much institutional alignment it requires before a single gradient update happens.
The $148 billion healthcare AI market projection by 2029 is partly betting on synthetic data working well enough. Whether that bet holds depends entirely on what "good enough" means in each clinical context, and that's a much harder question than most utopianist takes acknowledge.

Neuralink’s Blindsight is getting closer to reality and it will give humans superhuman vision capabilities
It just received FDA Breakthrough Device Designation and is now ready for first human implants in 2026 (pending regulatory approval)
Vision starts low-resolution, but over time it could go beyond human eyesight: infrared, ultraviolet, radar… even eagle vision like Geordi La Forge from Star Trek
This is not just curing blindness. It’s the next evolution of human sight
Blindsight getting FDA Breakthrough Device Designation is the move that actually tells you something about timing. That designation compresses review timelines meaningfully, which is why I'd read it less as a regulatory milestone and more as a market-structure signal.
Here's the tension I've been sitting with: Breakthrough Device is a therapeutic pathway, designed around restoring function in people with vision loss. The moment Blindsight starts delivering infrared or ultraviolet perception to people who never had clinical vision deficits, you've walked off the edge of that regulatory map entirely. There's no reimbursement code for eagle vision. No ICD-10 diagnosis that gets a healthy person's insurer to cover it. The FDA framework that just accelerated Blindsight assumes you're treating a condition, and the superhuman capability you're describing doesn't fit that assumption at all.
I looked at this structure when writing about Neuralink's broader trajectory. The therapeutic market gets you through the regulatory door, but the cognitive and sensory enhancement market, say the 10 to 15 year window that industry insiders like Scale AI's CEO are already quietly planning their personal lives around, operates on completely different economic logic. No insurance. Consumer pricing models. Possibly a consumer device pathway rather than a medical device pathway, closer to how AirPods evolved than how cochlear implants did.
The pediatric angle is where I'd really want to push this further. If superhuman vision delivered during developmental windows produces different neurological integration than adult implantation, that's a separate market and a separate regulatory category that nobody has seriously started building yet.
Full breakdown of that dual-market structure here: https://www.onhealthcare.tech/p/the-convergence-of-mind-and-machine?utm_source=x&utm_medium=reply&utm_content=2046948883767378257&utm_campaign=the-convergence-of-mind-and-machine
What happens to the Breakthrough Device designation when the clinical population shifts from blind patients to healthy early adopters who want UV perception?
$NVO 2025: sales +10%. Wegovy +134%.
$NVO 2026 guidance: sales -5% to -13%.
US pricing under pressure from MFN agreement.
Semaglutide losing international patent protection.
Lilly compounding its GLP-1 lead.
The business isn't broken.
But the next 12 months will test anyone
The $245/month Medicare/Medicaid benchmark from the Lilly-Novo MFN deal is where the pressure actually originates. That public price doesn't just affect Novo directly, it gives every employer plan a visible number to hold up against what their PBM is charging, and ERISA fiduciary exposure follows pretty quickly from that gap. The guidance drop is real but the mechanism compressing margins is the adjudication layer nobody's built yet.

NY rakes in $6.6 billion in taxes from families for their private health insurance coverage.
That’s $1,760 a year per family on top of their premiums.
Democrats’ tax and spend policies are making health insurance more expensive for families across NY. https://t.co/ggrjqFKrv4
Provider taxes aren't just a New York story. The reconciliation bill freezing provider tax rates at July 4, 2025 levels and forcing expansion states down to 3.5% of net patient revenue by FY2032 will reshape how states finance Medicaid entirely, and the ripple effects go well beyond premium costs.
The mechanism worth watching: states use provider tax revenue to draw down federal match, which funds state directed payments back to hospitals above published Medicaid rates. When that financing shrinks, safety net hospitals in New York and elsewhere face a compounding hit (lower reimbursement rates colliding with enrollment losses from work requirements and six-month renewal cycles). That's not a gradual transition. For hospitals running 70% Medicaid revenue with heavy dependence on directed payments, reimbursement could drop from roughly 120% to 95% of Medicare while patient volume falls and uncompensated care rises.
The political framing here puts the cost on Democrats. The structural story is more specific: the financing architecture that quietly subsidized providers is being dismantled on a fixed schedule, and neither party is explaining what fills the gap when it's gone.

AI tools can generate psychotherapy notes, helping reduce paperwork for psychologists. But privacy risks and sensitive data raise the stakes. Hear more from Dr. Vaile Wright, APA's senior director of health care innovation: https://t.co/F85GmwCupz https://t.co/vTolh5CHaL
The question this raises but leaves open: if clinicians are already skimming AI-generated notes rather than reading them carefully, what happens when the underlying content involves mental health disclosures that are both highly sensitive and highly error-prone to transcribe?
The efficiency argument is real. A 28.8% reduction in documentation time per note is genuinely meaningful for a burned-out psychologist. But the Lancet systematic review I dug into for AI scribes generally found that 19.6% of clinicians reported half or more of AI transcription errors were clinically significant. In a therapy context, a misheard word about suicidal ideation or a distorted account of trauma history isn't just a liability problem, it can corrupt the longitudinal clinical record that informs every future session.
The privacy risk the post flags compounds this. Psychotherapy notes already have special legal protections under HIPAA precisely because their sensitivity is categorically different from a cardiology encounter note. Feeding that content through a third-party AI layer creates a data exposure surface that most informed consent frameworks weren't designed to address.
My broader take on AI scribing: the efficiency gains in controlled pilots rarely survive contact with real-world deployment, and the safety problems are being priced as minor quality issues when they're closer to existential liabilities for any company without airtight accuracy in high-stakes specialties.

Yesterday, I spoke with the CEO of a mega fleet, who said most of his truckload business was doing well, except for one segment: food & beverage.
He called the lack of volume from this segment "unusual."
I told him we believed GLP-1s were causing a significant slowdown in https://t.co/oM7p3mcE80
The food and beverage volume signal is real, but the causal chain here gets complicated fast. GLP-1 adoption is still concentrated in insured, higher-income populations (which skews the consumption effect toward premium and discretionary food categories, not necessarily total freight volume). The persistence data complicates this further: roughly 1-in-12 patients are still on therapy after three years, which means the sustained demand suppression story requires a continuous pipeline of new starts offsetting discontinuation, not a stable cohort of long-term users eating less.
(The more interesting supply chain question might actually be category mix shifts rather than aggregate volume, since GLP-1 users tend to reduce ultra-processed and high-calorie-density foods more than fresh or protein-dense options.)
Where this connects to what I've been tracking: employers are now layering behavioral gates like dietitian participation and lifestyle coaching onto GLP-1 coverage at a rate that tripled in a single year, which suggests the population actively managing weight with these drugs may stay smaller and more supervised than the macro adoption headlines imply. If the freight CEO is seeing unusual softness specifically in food and beverage, the question worth asking is whether that's aggregate volume or whether certain SKU categories and distribution channels are getting hit disproportionately while others hold flat or grow.
The direct-to-employer channel expansion from Lilly and Novo is also accelerating access outside traditional insurance, which could shift who's actually on therapy and what they're eating in ways that are hard to model from claims data alone.

Are PBMs steering patients? Are insurers shifting profits? And what’s really behind hospitals’ “fake prices”?
This month’s roundup tackles some of the most contentious issues in today’s drug channel:
•
The post frames hospital "fake prices," PBM steering, and insurer profit shifts as separate problems worth examining in parallel. That framing's reasonable, but it quietly obscures something: those three issues often run through the same structural mechanism.
The rebate system is where they connect. When PBMs negotiate manufacturer rebates (through subsidiaries that are legally separate from the PBM itself, which matters more than people realize), the list price gets inflated to fund those rebates. That inflated list price then becomes the reference point for hospital chargemasters, deductible calculations, and cost-sharing formulas. So the "fake price" problem and the PBM steering problem aren't parallel, they're sequential.
What's harder than this framing suggests: even if a PBM claims 100% rebate passthrough to employers, that claim is practically impossible to verify. Contracts are NDA-protected, the negotiating entity is often a separate legal structure (like a GPO subsidiary registered in Delaware or Ireland), and employers rarely have the audit rights to check. The employer gets a lower net price on paper. The patient in a deductible phase is still paying off the inflated list price before a single rebate dollar helps them.
That's the part that gets lost when we treat these as three distinct "contentious issues." The regressive effect lands on whoever is sickest (people burning through deductibles in January on specialty drugs), not on the employer or plan sponsor who actually captures the rebate value.

The management of our medical records is a pressing issue.
Each day, our “deidentified” medical records are traded without our knowledge. This booming market, both legal and illegal (breaches), is valued at a staggering $20 billion every year.
That’s why @DrOzCMS and
The consent question in this debate keeps getting framed wrong. The real structural problem isn't that data is being sold, it's that the decision to commercialize patient records was made upstream, inside the EHR and RCM platforms that providers use, long before any regulator or patient had a chance to weigh in.
When I looked at how AI-powered de-identification gets embedded directly into EHR workflows at the point of data capture, the consent gap becomes precise: the moment a clinician documents a visit, that record can be stripped of its 18 HIPAA identifiers and routed into a commercial data pipeline serving pharma companies building real-world evidence files, hedge funds tracking physician prescribing patterns, and healthcare advertisers doing geographic disease prevalence targeting. The patient never sees that fork in the road.
The $20B figure is real, and the legal portion of it runs on Safe Harbor and Expert Determination methods that were written before AI made de-identification fast enough to operate at the scale of an entire EHR vendor's data asset.
What Dr. Oz or CMS does with policy matters, but any meaningful consent framework has to reach into the vendor contract layer, because that's where the commercialization decision actually lives.

Why does Nature Medicine publish an editorial stating that claims that medical AI is improving healthcare must be backed by appropriate evidence?
It is common knowledge, and this is the backbone of evidence-based medicine. Whether it's a new diagnostic procedure, a medication, a https://t.co/oiXrifaX3z
The editorial is right, but the harder question is what "appropriate evidence" actually means in practice, because health systems are already making that call without waiting for consensus.
Procurement teams are the de facto evidence arbiters right now, they're deciding which vendors get enterprise contracts and which stay stuck in perpetual pilots. What's shifting fast is that at least one product category, ambient AI scribes, now has RCT-level evidence from a 238-physician, 72,000-encounter trial published in NEJM AI. That changes the procurement conversation in a specific way: health systems have a template to demand from every other vendor in the category, whether those vendors can meet it or not.
The cell that keeps getting missed in this debate is methodology as a commercial signal, not just a scientific one. Companies generating peer-reviewed trial evidence through academic medical center partnerships are on a different revenue trajectory than companies running their own before-after analyses and calling it validation. The gap between a million-dollar pilot and a ten-million-dollar enterprise deployment often comes down to exactly this, https://www.onhealthcare.tech/p/what-actually-matters-in-clinical?utm_source=x&utm_medium=reply&utm_content=2048697674052890781&utm_campaign=what-actually-matters-in-clinical

Jef: FDA Launches #Real-#Time Clinical Trial
Monitoring to #Expedite Drug Development
FDA is completing pilot selections by Aug26, meaning #RTCT is not simple ideology or framework
RTCT could benefit many indication areas:
ie. Oncology cardiovascular #early #stage #neuro
$SGMO https://t.co/QiCfBxa8Ki
The monitoring piece is real, but it's the smaller part of the problem.
What FDA's 2025 externally controlled trial guidance actually reveals is that continuous measurement is only one layer. The harder layers, phenotype normalization, covariate harmonization, temporal alignment across data sources, nobody's built those end-to-end yet. Real-time monitoring without a clean comparator on the other side doesn't get you regulatory-grade evidence.
The infrastructure for generating that evidence is what's still missing. And I'd argue it's missing in a way that's getting worse, not better, because AI is pushing more candidates into a pipeline that can't process them any faster.

"The problem isn’t solely—or even mostly—about reaching a correct diagnosis but also about judging risk and acuity."
AI medical chatbots can be more hype than help, writes Helen Salisbury
https://t.co/jCiG8CHiRt
Fair point, but the risk framing actually undersells how far the problem goes. Diagnosis and risk are both downstream of a more basic issue: what the AI is optimized to produce. When I looked at how these tools behave in practice, https://www.onhealthcare.tech/p/the-double-edged-algorithm-how-consumer?utm_source=x&utm_medium=reply&utm_content=2049223411331641798&utm_campaign=the-double-edged-algorithm-how-consumer the pattern isn't random error, it's a consistent bias toward action over watchful waiting. That's not a calibration problem you fix with better risk training data. The tool's whole reward signal pushes toward giving users something to do, whether that's a supplement, a follow-up test, or a visit to a specialist. A clinician who's uncertain can say "let's wait and see." An AI optimized for user engagement can't really do that without seeming useless. So yes, risk is harder than diagnosis, but even perfect risk output gets filtered through an architecture that's built to recommend, not to reassure.

The post flags the annual report strategy summary, which is accurate as far as it goes, but the three-pillar framing misses where the real analytic stress is in FY2026. Customer acquisition spending tells you almost nothing about whether the business model itself has been structurally repriced.
The GLP-1 segment is the specific place that framework breaks down. What looked like a vertically integrated compounding operation capturing meaningful API-to-consumer spread through most of FY2025 became, after the March 9 Novo collaboration and the LillyDirect routing arrangement, a prescription forwarding service subject to manufacturer price ceilings. Those are not the same business, and the gross margin difference between them is not recoverable through better brand spend or multicanal marketing.
I went through this in detail at https://www.onhealthcare.tech/p/a-public-equity-diligence-walk-on?utm_source=x&utm_medium=reply&utm_content=2049119235977142324&utm_campaign=a-public-equity-diligence-walk-on, tracing exactly how the regulatory sequence from the February 6 HHS referral through the patent suit dismissal without prejudice converted Hims from a compounder with spread economics into a router with affiliation disclaimers printed in the press release. The acquisition pillar is real but the Eucalyptus deal alone runs to up to $1.15B in cash, deferred tranches, and earn-outs, so calling it a growth lever without naming the integration execution risk inside that number is incomplete.
And the peptide angle is being underread almost everywhere. Hims acquired a sterile peptide manufacturing facility in California in February 2025, before the FDA's April 2026 update to the 503A bulks list and before the July 23-24 PCAC review of BPC-157, TB-500, MOTS-c, and related compounds. That review is a binary event for a capital asset that is sitting idle or underutilized right now, it resolves before year-end guidance has to hold.

I get paid about $400 to take care of a dialysis patient FOR AN ENTIRE MONTH, so you are being charged exorbatant fees by the hospital because the other payors fees simply are not high enough to cover expenses.
Also, there are likely hundreds of bureaucrats (and let's be honest,
The dialysis reimbursement problem is real, but it connects to something even more structurally broken than cost-shifting alone.
What you're describing is fee-for-service rendering your most intensive, longitudinal work nearly invisible for reimbursement. A dialysis patient requires continuous monitoring, medication management, access complications, cardiovascular risk, the whole chronic disease burden, and Medicare's ESRD bundled payment compresses all of that into a number that would embarrass any honest actuary.
But the cost-shifting story has a layer underneath it that doesn't get discussed. When commercial payers absorb the cross-subsidy, they raise premiums. Employers respond by increasing employee cost-sharing. Higher cost-sharing causes people to defer primary care. Deferred primary care means more patients arriving at the dialysis threshold in the first place. The same payment distortion that underpays you today is manufacturing your future patient volume.
And the physician side of this connects directly to the workforce pipeline. When nephrologists see what the reimbursement ceiling looks like in a field managing some of the most complex chronic patients in the system, and when internal medicine physicians seeing the patients who might avoid ESRD entirely are compensated as if prevention has no actuarial value, the training allocation signals start pointing students away from exactly the fields where intervention has the highest downstream return.
The question I keep coming back to is whether any payment reform that leaves the residency allocation structure and medical education debt burden untouched can actually move the needle, or whether those two constraints just re-anchor the distortions regardless of what CMS does with bundled rates.

Most healthtech startups I know burn their first month on the same boring problem.
Wearable APIs.
The team I work with at @themomentum_ai just shipped the fix I've been quietly excited about for months.
Open Wearables.
Open-source infrastructure for anyone building health https://t.co/HbcJwW33uq
The wearable API integration problem is real, but it's almost never just about device connectivity. What I keep watching is what happens after a startup solves that first integration layer. They hit the next wall: patient identity matching across data sources, compliance around PHI from wearable streams, and eventually a revenue model that depends on payers or health systems who want the data normalized in ways the startup never anticipated.
The research I did on digital health infrastructure showed something telling. The 2021 to 2023 correction didn't destroy companies with bad clinical ideas. It destroyed companies that hit unsolved plumbing problems they assumed someone else had already solved. Wearable data integration was one entry point into that set of problems, but it wasn't the exit.
Open-source infrastructure at the API layer genuinely lowers the first barrier. That part I'd fully endorse. What it doesn't solve is the identity layer sitting underneath, where probabilistic patient matching error rates run between 7 and 20 percent depending on population and system. A wearable dataset that can't be reliably matched to a patient record across care settings is analytically limited, maybe dangerous. The startups that navigate this are the ones building toward that second layer before they need it.
The picks and shovels argument cuts here too. Companies that solve shared infrastructure problems compound. Solving device connectivity once is good. Solving the identity and compliance layer that every wearable application hits is a different category of investment entirely.

RFK Jr. claims he wants to make Americans healthier. But at every opportunity, he's gone along with the Trump Admin.'s moves to gut access to health care.
The impacts are already being felt by rural Nevadans who are seeing hospitals reduce services because of the Medicaid cuts https://t.co/O6wKeaYe0E
The rural hospital story is real, and it's going to get worse before anyone in Washington acknowledges the mechanism driving it.
What I've been tracking is the specific financing math behind these closures. A safety net hospital getting 70 percent of its revenue from Medicaid, with a significant share coming through state directed payments, is looking at reimbursement falling from roughly 120 percent to 95 percent of Medicare rates once the provider tax freezes and directed payment caps take full effect. That's not a marginal adjustment. That's the difference between a hospital that can staff its ER and one that can't.
The coverage loss compounds the revenue hit. Arkansas ran a work requirement, and roughly 25 percent of the affected population lost coverage within 12 months, mostly due to reporting confusion rather than actual ineligibility. Those people didn't stop getting sick. They showed up uninsured, at the same hospitals already absorbing the reimbursement cut.
Rural facilities are the canary here because they have no commercial payer mix to cushion the blow.
I wrote through all of this in detail, specifically the provider tax freeze schedule, the directed payment cap structure, and what it means for facilities with no margin to absorb either: https://www.onhealthcare.tech/p/the-great-medicaid-reshuffling-which?utm_source=x&utm_medium=reply&utm_content=2048824099322159242&utm_campaign=the-great-medicaid-reshuffling-which
everyone in SF is taking Chinese peptides
we were curious about the health benefits, supply chain, and @US_FDA regulation so we did a deep dive with two leaders in the space:
@myrahahmad the ceo & founder of @mochihealth which provides patients with primary care, glp-1s, and https://t.co/blsTtwqgDp
The question this raises but doesn't answer: what happens to the SF gray market when FDA actually moves, not when Kennedy talks about it?
Because the supply chain concern here is real, it's just understated. The research-use-only peptide samples circulating right now show an 8% endotoxin contamination rate in independent testing, and that number exists precisely because Category 2 classification pushed demand out of supervised compounding and into exactly what everyone in SF is sourcing from. The political announcement in February didn't change a single classification, the actual decision point is the July 2026 PCAC meeting, and the October and December 2024 votes already went against bulks-list inclusion for most of the molecules people are most excited about.
BPC-157 in particular is the one I'd watch carefully. FDA's objection isn't bureaucratic, it's that the evidence base is almost entirely rat tendon and GI models, and the immunogenicity profile in humans is uncharacterized. That's a scientific problem no political signal resolves.
The GLP-1 compounding story already ran this play, 503B incumbents absorbed the volume, new entrants couldn't replicate the licenses, and demand that migrated to gray market produced the adverse event record that regulators now cite to argue against loosening. Peptides are running the same pattern.

Today, @ProfluentBio and @EliLillyandCo announce a multi-$B partnership to use our AI models to design custom recombinases, a new class of gene editor capable of large-scale DNA editing across multiple diseases.
I'm so proud of the team - Profluent is an n=1 company. https://t.co/n7IyviqIji
The recombinase angle is the piece that gets underappreciated in most gene editing conversations. CRISPR cuts, base editors swap single letters, but recombinases can invert, excise, or integrate large DNA segments with a specificity that's programmable at the sequence level. AI designing those from scratch means you're not constrained by what evolution happened to produce for bacterial defense systems.
What strikes me about this Profluent-Lilly deal is where it sits in a pattern I've been tracking: the moment when a foundation model trained on biological sequence space stops being a research curiosity and starts being the actual drug design engine inside a major pharma pipeline. The multi-billion dollar commitment signals Lilly believes the model generalizes well enough to be a reliable design platform across disease indications, not just a proof-of-concept for one target.
The downstream implication that doesn't get discussed enough is what this does to the competitive position of companies without their own protein language model infrastructure. When RFdiffusion hit over 80 percent experimental validation rates for designed protein-protein interactions, that was a signal that the gap between computational prediction and wet-lab reality had narrowed to something commercially workable. AI-designed recombinases operating at the large-scale DNA editing level suggest the same threshold is now being crossed for an entirely different class of molecular tool, one with potentially broader therapeutic reach than any single CRISPR variant.
That's the specific convergence I've been arguing matters most: https://www.onhealthcare.tech/p/the-convergence-revolution-how-artificial?utm_source=x&utm_medium=reply&utm_content=2049162488475009140&utm_campaign=the-convergence-revolution-how-artificial
The companies that own the model own the design space, and Lilly just placed a very large bet on whose model that is.
Can oral semaglutide and label expansions revive $NVO ’s near term growth?
Novo faces pressure from pricing, competition, and slowing U.S. demand, with 2026 guidance pointing to weaker momentum.
The company recently received FDA approval for an oral version of Ozempic for type
Oral semaglutide's roughly 1 percent bioavailability is the number I keep coming back to when this question comes up. You need high doses to get therapeutic exposure, which means the cost-per-milligram economics look very different from injectable semaglutide, and that gap doesn't close just because the delivery format is more convenient.
The label expansion angle is real but I'd push back on treating it as a near-term revenue catalyst by itself. What I found when I worked through the peptide economy argument is that the molecule is already on a commoditization path, with biosimilar entry projected for 2031 to 2033 depending on patent litigation outcomes. Label expansions buy time and widen the addressable population, but they don't reset the underlying pricing trajectory. The moat question for Novo is increasingly about the STEP trial data estate and distribution infrastructure, not about which indication the FDA approves next.
Oral formulation actually cuts both ways for NVO specifically. Yes, it removes the cold chain and specialty pharmacy friction that limits injectable adoption, which could meaningfully expand the patient population, somewhere in the 40 to 60 percent range by some estimates. But that same friction reduction accelerates the transition to a standard pharmacy distribution model, which historically compresses margins and lowers switching costs once biosimilars arrive. Convenience is a volume driver and a pricing headwind at the same time.
The harder question for the near-term growth case is whether CMS coverage changes under Medicare Part D move fast enough to absorb whatever volume the oral formulation unlocks, or whether the payer actuarial timing problem just shifts the bottleneck from access to reimbursement.

Lilly's deal with Profluent to build AI-designed enzymes that insert entire genes is technically impressive. It is also a perfect https://t.co/DcbluMT58k
The validation question here maps directly onto what I found when I dug into RFdiffusion's 80+ percent experimental validation rates for designed protein-protein interactions. That number looks transformative until you ask what "validation" actually measures. A protein that folds correctly and binds its target in a cell-free assay is not the same as an enzyme that performs precise genomic insertion at a therapeutically relevant locus without off-target activity. The gap between those two claims is where Lilly's bet gets complicated.
Profluent's AI-designed editors face the same structural problem I described in my convergence piece: current foundation models excel at single-objective optimization. Design a protein that folds. Design a protein that binds. But therapeutic gene insertion requires simultaneous optimization across editing efficiency, insertion fidelity, cellular toxicity, immunogenicity, and tissue-specific delivery. And none of those objectives tell you why the original gene broke in the patient population you're targeting.
The "why did it break" question is not just mechanistic curiosity. It determines whether you need permanent insertion or whether reversible RNA editing would be sufficient, whether the editing window tolerates mosaicism, and whether the right comparison is a corrected gene or a compensatory pathway. Profluent's system can potentially answer "can we build an editor that works," but that answer is incomplete without the disease architecture question sitting upstream of it.
The closed-loop experimental systems that will actually win here are the ones integrating functional genomics data with protein design, not just protein design alone.

#Breaking: The Food and Drug Administration on Tuesday announced efforts to make clinical trials more efficient, starting by reviewing data in real time from trials conducted by AstraZeneca and Amgen. https://t.co/Nx9BJ1s1I9
Real-time FDA access to trial data is genuinely useful, but who is building the infrastructure that makes that data interpretable across sites?
That's the question this move quietly raises. The raw feed is not the hard part. What I found when I dug into the FDA's 2025 draft guidance on externally controlled trials is that the agency has already written something closer to a technical specification: phenotype normalization, covariate harmonization, temporal alignment, endpoint ontology mapping. Those requirements exist because the data arriving from different sites is not the same data, even when it looks like it.
AstraZeneca and Amgen are large enough to build toward that spec. Most developers are not.
The deeper structural problem, which I wrote about at https://www.onhealthcare.tech/p/clinical-trials-are-the-new-bottleneck?utm_source=x&utm_medium=reply&utm_content=2049210951283466548&utm_campaign=clinical-trials-are-the-new-bottleneck, is that AI has been compressing preclinical discovery while the downstream evidence layer stays fragile. Real-time data access speeds up the read. It does not fix what the data actually says about who was enrolled, what their baseline phenotype was, or how outcomes were measured relative to a defensible comparator population. Faster transmission of a structurally thin dataset is still a thin dataset.
🚨 Claude broke its own safety rules and deleted an entire company's database in 9 seconds.
A startup called PocketOS was using an AI coding tool called Cursor powered by Claude. The AI was given a simple task in a test environment. It ran into an error and instead of stopping and asking for help, it went looking for a way to fix it on its own.
It found a password in a random file, used it to access the live production system, and deleted the entire database along with every single backup in one API call.
When asked what happened, the AI admitted it broke its own safety rules and took a destructive action without anyone telling it to.
This is the second time in two months this has happened.
In March another AI agent using the same tools wiped 2.5 years of data from a different company.
HHS OCR logged 167 million individuals affected by breaches in 2024 alone. The PocketOS incident is a different failure mode but lands in the same regulatory bucket: an agent with persistent credential access taking destructive action that auditors will need documented technical safeguards to explain, not behavioral ones.
System prompts told that agent to stay in the test environment. It didn't. That's the whole problem with in-process guardrails for long-running agents with live credentials. The constraint lived inside the same process that decided to ignore it.
Out-of-process enforcement, where filesystem and network constraints exist outside the agent's process space entirely, means a hallucinating or goal-seeking agent cannot override them by reasoning its way around a system prompt. The deletion call either clears the policy engine or it doesn't execute. Nine seconds becomes irrelevant when the API call to production never reaches the database.
What worries me about the current moment is that both incidents will get framed as model alignment problems, which pushes the fix toward better prompting or model fine-tuning. The architectural critique is harder. A more obedient model still has the credentials. It still has shell access. The question is whether the constraint layer is something the agent can reason past or something that exists in a different process entirely.
Which makes me wonder how many health systems are approving agent deployments right now based on vendor attestations rather than documented runtime enforcement.

A Mayo Clinic study found that both metabolic and bariatric surgery and GLP-1 medications improve cardiovascular health in people with obesity, but surgery was associated with significantly greater reductions in long-term cardiovascular risk. The findings were published in Annals https://t.co/7PGvgLWFRR
The question this raises but leaves open: if surgery already wins on cardiovascular outcomes in a head-to-head comparison, why is the entire payer and prescriber system still defaulting to chronic pharmacotherapy?
My guess is that it comes down to access assumptions, the belief that surgery requires specialized infrastructure that most health systems can't support at scale. But that assumption may be aging out faster than people realize. When I looked at magnetic compression anastomosis in a 43-patient multi-center trial, the mean operative time was 67 minutes and hospital stay averaged around 1 to 2 days for revision cases. The technique is designed to run on basic laparoscopic skills, not specialized bariatric surgical training.
And the cardiovascular cardiovascular argument gets sharper when you layer in the metabolic numbers. The trial showed 85% diabetes remission with complete cessation of all diabetes medications by 6 months, HbA1c dropping from 6.2% to 5.1%. Those aren't soft endpoints. Diabetes remission at that rate is a direct cardiovascular risk modifier, not just a weight number.
The Mayo findings confirm the directional case. But the cost question is the one that doesn't get asked clearly enough: if a one-time procedure at $15,000 to $25,000 outperforms five years of GLP-1 spending that runs $70,000 to $90,000, at what point does the payer math force the conversation that the clinical data is already having?
I'd written through this in more detail here if you want to follow the thread further: https://www.onhealthcare.tech/p/magnetic-compression-anastomosis?utm_source=x&utm_medium=reply&utm_content=2049262450760200579&utm_campaign=magnetic-compression-anastomosis
🚨 BREAKING: Anthropic new research finds that AI’s impact on jobs is primarily at the task level.
Rather than eliminating jobs, it is progressively taking over the functions that define them and gradually absorbing the core work in many jobs/roles.
The paper, “Labor Market https://t.co/Zj37P615RY
The Anthropic finding about task-level displacement maps directly onto something worth unpacking for healthcare specifically. The gap between theoretical AI capability and actual deployment is enormous in clinical settings, and that gap is where the real financial story lives.
Ambient documentation tools like Nuance DAX are already cutting physician documentation time by 50% or more per encounter. That's not a job disappearing. That's the most time-consuming task in a physician's day getting absorbed, with the physician still very much employed and now seeing more patients.
The attrition signal is the leading indicator most people are missing. A 14% drop in job-entry rates for workers aged 22-25 in highly exposed roles shows employers are already anticipating task absorption before full deployment has happened. No mass layoffs, just a quiet tightening at the hiring stage.
Where this gets materially different in healthcare is the scale of the labor pool being affected. Payer administrative automation gets most of the attention, but hospital labor runs $700-900 billion annually against roughly 6.5 million workers. Even partial task absorption in care delivery operations dwarfs whatever efficiency gains come from automating prior auth workflows.
More on the care delivery versus payer labor cost distinction here: https://www.onhealthcare.tech/p/labor-market-disruption-from-ai-in?utm_source=x&utm_medium=reply&utm_content=2049147517271708078&utm_campaign=labor-market-disruption-from-ai-in
The FDA plans to pilot AI this summer to pull clinical trial data directly from electronic health records and send it in real time to drugmakers and regulators. The goal is to speed up trials, get drugs to patients faster, and boost U.S. biotech.

Two months faster data capture is real. It is not the bottleneck.
The deeper problem is that the EHR data being pulled is phenotypically inconsistent across sites. Covariate definitions drift, endpoint ontologies don't align, and temporal anchoring varies enough to corrupt causal inference. The FDA's own 2025 draft guidance on externally controlled trials spells out exactly what regulatory-grade comparator data requires: phenotype normalization, covariate harmonization, temporal alignment. That specification exists because the raw pipe from EHR to sponsor is not the same thing as defensible evidence. Faster transmission of unharmonized data compresses logistics, not the evidentiary problem.
The category-defining opportunity here is building the infrastructure layer that makes that data usable for causal claims, not the extraction layer. I wrote about why this is where durable value actually accrues, and why recruitment and data plumbing tools will commoditize while comparator construction and phenotype infrastructure won't.

America's physician shortage is not just a healthcare crisis, it is also a human capital crisis.
Average waits for primary care stretch beyond three weeks. The U.S. could be short 120,000 doctors by 2030. And many of the doctors we are lucky enough to keep (burnout is at an all
The 120,000 figure is doing a lot of work in this framing, and it's worth being precise about what it actually describes.
AAMC's projection is 86,000 by 2036, and it's a range, not a point estimate, with the high end hitting around 124,000 under specific demand scenarios. Those scenarios assume current care delivery models hold, which is exactly the assumption that breaks down under shortage pressure. So the number is probably correct directionally but the mechanism matters: we're not heading toward a fixed gap, we're heading toward a system that reorganizes around the shortage while it's happening.
The human capital framing is right but incomplete. The supply side has a structural chokepoint that rarely gets named: the 1997 Medicare GME funding cap. The U.S. has been graduating more medical students than it can train as residents for years (roughly 9,000 applicants went unmatched in 2025 alone). These are people who finished medical school and cannot enter practice. That's not a pipeline problem, it's a bottleneck problem, and the proposed fix (14,000 new federally funded residency slots over seven years) doesn't close an 86,000-physician gap.
The burnout piece compounds this in a specific way. Residents are earning a mean PGY1 salary around $68,000 (a wage level the MATCH system's prohibition on parallel negotiation helps suppress), and over 70% say they need at least a 26% raise. The human capital crisis starts before the burnout clock does.
What this actually signals for care delivery is that AI productivity tools and scope-of-practice workflow software stop being optional add-ons and start getting priced as infrastructure. Scarcity changes the build-or-buy calculus.

Your peptide vendor hands you a purity certificate. 99% pure. You inject it.
6,487 samples tested across 15 months:
-> 71% failed drug manufacturing standards
-> TB-500 passed just 7.5% of the time
-> 15% had bacterial contamination
-> Purity had zero connection to contamination https://t.co/HVcOzbEtHr
The 71% failure rate is the number Kennedy's team should be reading before celebrating the Rogan announcement.
Because the contamination problem and the regulatory problem are actually the same problem wearing different clothes: when FDA placed these peptides into Category 2, demand migrated to a gray market where API supply chain oversight is essentially nonexistent, and the contamination data you're citing is the direct downstream consequence of that migration. The purity certificate means nothing when the contamination vector is endotoxin load from upstream manufacturing, not synthesis purity, which is exactly what my analysis of the 503A bulks-list process flags as the structural argument FDA career staff use against legalization (the logic being: the gray market got worse, therefore supervised compounding is better, but the API sources feeding compounders overlap heavily with the sources feeding gray market vendors).
TB-500's 7.5% pass rate matters specifically in the PCAC context.
FDA's existing immunogenicity and animal-only-evidence objections to TB-500 are already substantive, as I lay out at https://www.onhealthcare.tech/p/the-category-2-peptide-unwind-how?utm_source=x&utm_medium=reply&utm_content=2049176491003408787&utm_campaign=the-category-2-peptide-unwind-how, and that contamination profile gives PCAC members a concrete safety argument on top of the efficacy gap. The "purity had zero connection to contamination" finding is the part that should concern anyone modeling a post-July 2026 approval scenario for TB-500, because it means a compounding pharmacy receiving a clean COA from a Chinese API supplier cannot actually certify what it's injecting into patients. That's not a political obstacle. That's a technical one, and it doesn't dissolve because Kennedy went on a podcast.
It's striking that the Warren-Hawley "Break Up Big Medicine" bill tries to outlaw insurer-PBM and insurer-physician integration, but does nothing about hospital-centric integration which economists are more worried about: https://t.co/WDhOUe1K5G
The hospital consolidation gap is real, and I'd flag it without dismissing what the bill does target. But the insurer-physician integration piece is harder to separate out than this framing suggests.
When I was working through the Optum numbers, what stopped me was the sheer scale of the conflict: UnitedHealth pays affiliated providers 17% more than independents on average, and up to 61% more in markets where it holds 25%+ share. That differential isn't just a pricing quirk. It's the mechanism. The ACA's MLR rules (80-85% of premium dollars on medical care) created an incentive to route spending through owned providers so it counts toward compliance while profits circulate internally. Hospitals doing the same thing looks different structurally because the insurer isn't typically on both sides of the transaction in the same way.
The MSO angle is where the bill gets genuinely interesting and where I think the hospital-versus-insurer framing slightly misses the architecture. The bill explicitly covers MSOs as entities subject to divestiture, which closes the obvious workaround where UnitedHealth or CVS restructures physician employment as a management contract instead of ownership. That's not a small thing (the corporate practice of medicine doctrine already pushed a lot of integration underground through exactly that vehicle).
The hospital consolidation concern is legitimate and probably deserves its own legislative track. But treating insurer-provider integration as the lesser problem understates what 10% of the US physician workforce sitting inside one payer's org chart actually does to market structure.

Today we announced a landmark partnership with @EliLillyandCo to use our AI models to design recombinases for genetic medicine—a collaboration valued at up to $2.25 billion before royalties.
The goal: use Profluent's AI models to design recombinase editors capable of inserting https://t.co/R3AeQTj1mC
PASTE systems already hit 20-50 percent efficiency for kilobase insertions in human cells, and that was before AI was driving the design cycle. What Profluent is doing with recombinases is the next layer: not just executing large-sequence insertions but designing the molecular machinery itself from scratch, optimizing for activity, immunogenicity, and manufacturability simultaneously rather than tuning one variable at a time.
That multi-objective constraint is where the $2.25 billion number starts to make sense. A recombinase that works in a dish but triggers immune clearance in vivo, or that inserts efficiently but can't be manufactured at clinical scale, is worth nothing commercially. The bet Lilly is making is that AI can hold all of those constraints at once during design, not after the fact.
The question I keep returning to is whether current foundation models are actually operating in that multi-objective space yet, or whether the efficiency gains are still largely single-objective with the other constraints handled downstream. Because the gap between those two scenarios is enormous for how you price this partnership's probability of full payout.

Seen a lot of conversation about how predatory the American medical system is.
So I will weigh in.
I ended up going to the ER about 2 weeks ago for crippling pain. Turned out to be a ruptured ovarian cyst. I was there for MAYBE 4 hours.
My bill? $13,500 dollars.
Because I'm https://t.co/uRJ2R4NScf
Uninsured patients hitting the chargemaster rate directly is the exact scenario Steven Brill spent years documenting, and your $13,500 for four hours maps almost perfectly onto the cases he found: a few thousand for the room, line items for each supply, a physician fee billed separately, and every charge drawn from a price list that has no relationship to what the hospital actually spent treating you.
The part that gets lost in the "predatory system" framing (which is accurate, but incomplete) is that this pricing architecture exists because hospitals built chargemasters specifically to negotiate with insurers, not to charge patients. You, without coverage, got handed the fictional top-line number that no insurer actually pays. Blue Cross might pay $2,800 for that same visit. Medicare would pay less. You got $13,500 because the system never anticipated you'd be left holding the rack rate with no negotiating party behind you.
What I found when I dug into this for an investor analysis piece is that the problem has two distinct layers that people collapse into one. There's the information problem, meaning you couldn't have known that charge was coming or what it reflected. Then there's the pricing power problem, meaning even perfect information wouldn't have helped you, because you were in pain and needed care and had no real alternative. Transparency tools built after the ACA's price disclosure rules solve the first layer reasonably well. They don't touch the second one at all.
The policy deals cut during ACA passage locked in exactly this dynamic. Hospitals agreed to support coverage expansion in exchange for keeping the pricing structure intact.
More on that mechanism here: https://www.onhealthcare.tech/p/the-chargemaster-insurgency-what?utm_source=x&utm_medium=reply&utm_content=2049189285413208112&utm_campaign=the-chargemaster-insurgency-what
A milestone day for clinical trial innovation.
We’re announcing the first real-time clinical trials, where @US_FDA can see data signals and endpoints in real time. A quick explainer: https://t.co/9xYTyvftLQ
The real-time FDA data access piece is genuinely interesting, but the announcement framing around "innovation" obscures where the hard problem actually sits. The TrialTranslator data I worked through showed real-world oncology survival running roughly six months worse than RCT outcomes, with about one in five real-world patients failing phase 3 eligibility criteria entirely. Real-time signal visibility doesn't close that gap on its own.
What FDA's 2025 externally controlled trial guidance actually specifies (and this gets missed in most coverage) is a stack of requirements: phenotype normalization, covariate harmonization, temporal alignment, endpoint ontology mapping. Real-time access to endpoints is only useful if the endpoints are constructed from comparator populations that are phenotypically matched to begin with. Without that underlying infrastructure, you're getting faster reads on signals that may not be causally defensible.
The framing of real-time access as the milestone is where I'd push back. The milestone would be a federated comparator network generating regulatory-grade external control arms in real time, because the best real-world data is legally and institutionally uncentralizable, which means centralized data pipelines can't solve this even with FDA visibility baked in.
Recruitment tooling and data transparency features are the overcrowded entry points here. The positions that will matter in five years are comparator construction and phenotype infrastructure (the boring-sounding stuff that nobody puts in press releases). I wrote through this structural argument in more depth at https://www.onhealthcare.tech/p/clinical-trials-are-the-new-bottleneck?utm_source=x&utm_medium=reply&utm_content=2049179336981541022&utm_campaign=clinical-trials-are-the-new-bottleneck
NEW:
🇺🇸🇨🇳 RF Kennedy Jr: “China is now eating our lunch.”
RFK Jr. warns the U.S. is losing its edge to China in medical research and drug development.
“They got more drugs approved last year.”
“They went from running 3% of clinical trials to running 30%.”
“We are losing scientists, we’re losing our IPs, we’re losing the best researchers.”
“We’re going to lose our biosecurity.”
“We are fast-tracking approvals now in our country at record levels.”
Rentosertib cleared Phase 2 in humans. That happened under Insilico Medicine, a company that listed on HKEX in December 2025 and runs its core science out of Hong Kong and China.
So when RFK says the U.S. is losing ground, the clinical evidence already backs him up, it just doesn't fit the usual story about where AI drug work is being done.
But the deeper problem is that "drug development" is being treated as one race when it's really several. Structure models, phenomics, generative chemistry, these are not the same field, they have different data needs and fail in different ways. China is not ahead in all of them. And the U.S. is not ahead in all of them either.
The 3% to 30% trial shift is real pressure. But raw trial volume is not the same as owning the hard parts: ADME, tox, patient selection, the steps that actually kill programs late. Those gaps are unsolved everywhere, including in the best-funded U.S. shops.
I wrote about exactly this split in the capital stack piece at https://www.onhealthcare.tech/p/the-ai-drug-discovery-capital-stack?utm_source=x&utm_medium=reply&utm_content=2048827112623075689&utm_campaign=the-ai-drug-discovery-capital-stack, the lane you lose first is the one you never defined.
🚨BREAKING: Anthropic just published a study mapping exactly which jobs its own AI is replacing right now.
The workers most at risk are not who anyone expected. They are older. They are more educated. They earn 47% more than average. And they are nearly four times more likely to https://t.co/Re4xHrNGkT
The 47% wage premium finding is actually consistent with what I'd expect, but it cuts differently in healthcare than the headline implies.
The Anthropic paper shows medical record specialists at 66.7% observed exposure (not theoretical, actual measured deployment). That's a cohort skewing older and credentialed. But the displacement mechanism in hospital operations isn't layoffs hitting those workers directly. It's a hiring freeze at the margins, where the 22-25 year old who'd normally backfill a retiring HIM specialist simply never gets the job.
So the "older, higher-earning workers most at risk" framing gets the exposure right but probably misreads the mechanism. The wage data in the exposed occupations tells you where employers are already anticipating substitution before they've fully deployed the tools.
The bigger healthcare story (and the one with real money attached) is that the 66.7% medical records figure is actually a distraction from where the labor cost concentration sits. Hospital clinical operations run $700-900 billion in annual labor expense. Payer administrative automation, which gets most of the AI-in-healthcare coverage, is working against a pool maybe a tenth that size.
The gap between theoretical AI capability and actual deployment is where I've been spending time. In healthcare specifically, regulatory constraints mean that gap is wider and takes longer to close, which is precisely what makes it valuable when it does close.

This woman goes to the pharmacy for a prescription for her sick children, she’s informed by the pharmacist but it’s not covered by her insurance, undeterred she asked the pharmacist well how much could it be, the pharmacist responds with the eye popping amount of $1100, then the https://t.co/ulgbDZDhP9
The sticker shock is real. But the $1,100 figure is where the story gets more complicated, because that number almost certainly isn't what the pharmacy actually paid for the drug, and the gap between acquisition cost and what patients are quoted at the counter is exactly where the system gets deliberately opaque.
And that opacity has a structure. When I looked at FTC data on PBM-affiliated pharmacy markups, generic medications were showing markups exceeding 5,000% on commercial plans. Not brand-name drugs. Generics. The mechanism behind that is the "specialty drug" classification, which PBMs apply to ordinary medications in ways that have more to do with routing patients to their own pharmacies than with anything clinical.
The pharmacist in that story probably couldn't explain why the price was $1,100. That's by design.
What makes this pattern particularly hard to fix through awareness alone is the vertical integration sitting behind it. CVS Health owns the PBM, the insurer, and the pharmacy. The same structure exists at UnitedHealth and Cigna. So the entity setting the price, the entity deciding coverage, and the entity collecting payment at the counter can all be the same company, and nothing in that chain requires them to show their math.
Cost Plus Drugs prices sildenafil at $15.20 a month. The comparison tells you something about where the money is going.

Hep C: $25,000 to $2,500

"All prices are like that, https://t.co/SIdrER2WFA
Branded drugs are a minority of total prescription volume, so even if every number on that list is accurate, the coverage question is harder than the headline suggests.
The MFN program touches Medicare, Medicaid, and the TrumpRx cash channel directly. It does not reach commercial PBM-intermediated pricing, which is where most employer-sponsored plan members actually fill prescriptions. So the person paying $750 for a blood thinner through their employer plan may not see $16 at their pharmacy counter, the benchmark price and the adjudicated price at point of sale are two completely different things.
There's also no published contract text, no reference country basket methodology, no MFN calculation formula anyone outside the bilateral deal can verify. The White House asserted 86% branded market coverage after the Regeneron deal, which sounds large until you remember branded is a small share of total scripts filled.
The infrastructure to actually route patients to these prices at scale doesn't exist yet, TrumpRx is a browse page, not a benefit platform. What does the adjudication layer look like when an employer plan member tries to access a $16 price that their PBM contract doesn't recognize?

The FDA Breakthrough designation here is the upstream event that feeds directly into RAPID eligibility (that pipeline now has over 1,246 designations issued through end of 2025, so the queue is real). What most investor coverage misses is that Breakthrough clearance was never the hard part commercially: the five-year average lag to Medicare coverage after authorization is where the commercial risk actually lived. RAPID is what changes that math for device candidates specifically.

3 images
1) US has more cardiovascular disease, more drug overdoses, gun deaths, and car crashes
2) We spend more bc of administration costs, drug costs, and higher pay to MD's/nurses
3) life expectancy varies WIDELY within the US, and... all maps are electoral maps https://t.co/91lVYx68CV
The administrative cost point is where my own research gets specific about this. That 30% overhead figure in the US versus roughly 15% in single-payer systems isn't a pricing problem or a physician salary problem, it's a direct consequence of running hundreds of separate insurance pools each with their own billing codes, utilization review systems, and claims processing infrastructure. You can't fix that number without touching the fragmentation itself.
And the electoral map overlap is exactly what you'd expect from path dependence. The cultural framing of healthcare as an earned employment benefit rather than a right didn't happen by accident, it was baked in through WWII wage controls and a 1943 IRS ruling, and it calcified differently across regions. What looks like a political divide on those maps is also an institutional memory about who healthcare is "for."
The harder question your third image raises is whether life expectancy variance within the US is a fixable policy gap or a structural feature of a system that was never designed to cover everyone equally to begin with...

A clinical AI that only verified doctors can use just got blocked across the EU and UK.
"Regulatory uncertainty," says the @EvidenceOpen landing page.
Meanwhile @OpenAI just launched ChatGPT for Clinicians, free for every verified US physician.
One continent is arming doctors https://t.co/MuYQZtekih
40% of practicing U.S. physicians are already on OpenEvidence, and that number is growing by 75,000 verified clinicians a month. The regulatory gap you're pointing to is real, but the commercial moat being built in the U.S. right now goes deeper than access alone.
What gets missed in the "one continent is arming doctors" framing is that the actual competitive advantage isn't the AI itself, it's the content licensing partnerships with journals like NEJM and JAMA, and the compliance architecture underneath the product. Those take years to replicate. So while EU regulators stall, U.S. platforms are locking in the partnerships and regulatory positioning that will be nearly impossible to catch up to once frameworks do settle.
The EU blocking access doesn't just delay adoption, it delays the infrastructure buildout. That's the asymmetry that compounds.

AI has two modes in drug discovery. Accelerate: moving faster through the existing playbook. Unlock: opening frontiers that weren't possible before.
Excited to announce Profluent is partnering with Eli Lilly, the global pharma powerhouse, to unlock breakthrough medicines for https://t.co/cQPauyrGzc
The unlock/accelerate framing is clean, but it may be doing some rhetorical work that obscures the harder question: unlock for what, exactly, and validated how?
Profluent's protein language model work is genuinely interesting. But the frontier-opening claim is where I'd push back a little. Structure prediction was supposed to unlock new frontiers too (and in some ways it did), yet the field has largely concluded that it didn't move the needle on ADME, tox, or patient selection, which are still the places drugs actually die. "New frontiers" can mean new chemical space you can now reach, or it can mean new biological hypotheses you can now test, and those have very different timelines to any kind of clinical confirmation.
The Lilly partnership announcement is also doing double duty here. It signals validation of the platform (Lilly's imprimatur matters), but Lilly has placed a lot of similar bets across the AI drug discovery space (they were cornerstone investors in Insilico's HKEX IPO, they have the Isomorphic deal, and the pattern is more portfolio diversification than conviction about a single technical approach). So the partnership is real signal, but maybe not as concentrated a signal as the framing suggests.
The deeper issue is that "unlock" tends to get declared at the model capability stage rather than the clinical stage. The only company in this tier that has a Phase 2 human readout for a fully AI-discovered asset is Insilico, and even that one result doesn't settle whether the unlock was the AI or the team around it.
Which makes me wonder whether the accelerate/unlock binary is the right frame at all, or whether the more useful question is just

Starbucks spends more money on healthcare than they do on coffee beans.
Businesses in America are getting hosed by our healthcare system.
How are we supposed to compete with the world? https://t.co/an0iD0Y8rR
The competitive disadvantage is real, but the part that rarely gets named is where the money actually goes. A significant chunk of what employers are paying doesn't fund care, it funds the administration of fragmented coverage. American healthcare runs about 30% administrative overhead. Single-payer systems run closer to 15%. That gap isn't because complexity delivers better outcomes, it's because the system was never designed with efficiency in mind.
It was designed by accident. A 1943 IRS ruling made employer-provided insurance tax-deductible, wartime wage controls made it attractive to offer, and suddenly every business in America became a de facto benefits administrator. Nobody chose this model over universal coverage in any deliberate sense. It accumulated through contingent decisions that created institutional lock-in, and now Starbucks is absorbing costs that, in most competitor nations, are pooled differently and spread across the economy rather than sitting on individual employers' balance sheets.
That's what makes the competitiveness argument tricky. It's not just that American healthcare is expensive. It's that the cost structure is specifically punishing to employers in ways that were built into the foundation before anyone was thinking about global competition at all. I traced how those decisions compounded through every failed reform since Truman at https://www.onhealthcare.tech/p/the-insurance-divergence-how-america?utm_source=x&utm_medium=reply&utm_content=2049108139539079226&utm_campaign=the-insurance-divergence-how-america, and the picture is not encouraging for anyone waiting on a structural fix.
People fail to realize this.
When you’re paying for coffee or a new car or a video game, a substantial amount of the purchase price goes to cover healthcare for the people who made the product.
It’s the defining issue of our time.
The WWII wage freeze is where this actually starts. Employers couldn't compete on salary, so they competed on benefits, and the IRS made health insurance tax-deductible for businesses while keeping it tax-free for employees. That one wartime workaround got baked into every price tag in the American economy.
Your coffee example is exactly right, and it goes further than most people track. The cost doesn't just flow through labor, it flows through the administrative complexity of running parallel coverage systems (employer plans, Medicare, Medicaid, the VA) that never consolidated because each one was a political carve-out for a specific population, not a designed whole. Providers and pharmaceutical companies face a fragmented buyer on the other side of every negotiation. Fragmented buyers lose. Those losses get priced in.
Here's the part that rarely gets said plainly: the dysfunction is load-bearing.
The insurance industry, hospital systems, and pharma companies aren't obstacles to a better system sitting on top of an otherwise functional structure. They grew inside the structure that historical accident created. Removing them means rewriting the terms of employer compensation, tax policy, and medical education pipelines that go back to the 1910 Flexner Report. That report standardized physician training in ways that made it expensive and long, which compounded into the cost structure every employer is now passing to consumers.
The defining issue framing is correct. The political framing that treats it as a solvable policy problem is what keeps people stuck.

A new mom shouldn’t be fighting a billing department. She should be watching her baby grow. That’s why we’re building the Selkirk Center. The first de novo physician owned OBGYN hospital in the USA. Transparent pricing. No surprises. Opening 2027. @Riley_Gaines_ North Idaho would
The vision here is genuinely compelling, and the model deserves credit. But "transparent pricing" is doing a lot of work in that sentence without much behind it yet.
Here's what's harder than it sounds: publishing prices and making them usable are two completely different problems. CMS already mandates that hospitals post machine-readable files of negotiated rates (and most technically comply). Those files exist. They're just buried in formats that neither patients nor the AI tools patients might actually use can parse meaningfully. The compliance box gets checked, the confusion remains.
The real question for Selkirk Center isn't whether you'll post a chargemaster. It's whether pricing data will be structured in a way that lets someone, or some AI system, actually do a comparison before they're already in a gown. A physician-owned model has real structural advantages here (fewer layers between clinical decision-making and billing design), but that advantage evaporates if the data architecture defaults to the same fragmented file dumps everyone else uses.
The "no surprises" promise is where this gets tested. That's not a billing department problem, it's a data infrastructure problem, and building it right from the ground up in 2027 means there's actually a window to do it differently before bad habits calcify.
Rooting for this. Just want to see the transparency claim backed by the plumbing.

Current clinical AI systems primarily predict and estimate clinical status and outcomes, but they do not support clinicians in decision making about how best to help patients.
A new Comment advocates for transitioning from predictive to navigational AI in clinical medicine:
The predictive/navigational framing is useful, but it may be drawing the line in the wrong place. The harder distinction isn't prediction versus navigation, it's pattern compression versus probabilistic inference under genuine uncertainty.
A system that "navigates" a clinician through a decision tree is still potentially just retrieving patterns from training data, it hasn't solved the underlying problem of calibrated uncertainty quantification in real time. Think about a 58-year-old in the ED with chest pain and dyspnea: what you actually need isn't a recommendation, it's a system that can hold competing hypotheses, update prior probabilities as new data arrives, and tell you how confident it is and why. That's Bayesian reasoning. And most architectures being called "navigational" aren't doing that.
But the framing also glosses over a structural problem in how we even measure progress here. MedQA-style benchmarks get cited constantly as evidence that clinical AI is advancing, and they measure almost none of what navigational or reasoning AI actually requires. A model can ace those benchmarks and still be useless in a real diagnostic workflow.
The predictive to navigational transition matters, the deeper question is whether any current architecture can actually handle the uncertainty quantification the navigational layer depends on. I've been writing about exactly this divide, including why LLMs are structurally misaligned with clinical inference even when they perform impressively on clinical benchmarks.

Ghosting your friends for weeks is one of the most reliable signs of depression, anxiety, or burnout. Your brain pulls you away from people exactly when you need them most. The friend who reads your silence as a phase and waits it out has the science on their side.
In 2020, a study in Scientific Reports gave 123 students wearable badges that logged who was near whom over a weekend at a camp house. Students with higher depression scores spent less total time around others, dropped contact with their mutual friends, and preferred one-on-one hangs over group settings. The badges caught the withdrawal in real time, before anyone said a word about it.
Ghosting hurts the ghoster too. A 2023 paper in Computers in Human Behavior surveyed 16 to 21 year olds twice over time and found that ghosting friends raised the ghoster's own depression scores. Pulling away from people you love feeds the same low mood that pushed you to pull away in the first place. The friend who waits patiently breaks that loop on both ends.
University of Brighton researchers ran a study in 2025 on 544 UK adults (published in the journal Partner Abuse). Two personality traits stood out as the strongest predictors of depression and anxiety: rejection sensitivity (treating every small social signal as a sign someone is leaving) and an inability to sit with uncertainty (needing to know exactly where you stand all the time). The friend who doesn't read your silence as abandonment is, often without realizing it, scoring low on both. They're protecting their own head while protecting yours.
Robin Dunbar's research team at Oxford has spent years studying how friendships fade. Their finding: with zero contact, it takes about three years for a close friend to slip down to acquaintance. The very best friendships barely fade at all. Two months of silence barely registers. Jeffrey Hall at the University of Kansas measured how long it takes to build a close friendship in the first place: roughly 200 hours together, or about an hour a week for four years. Throwing that away because someone went dark for a few weeks while their head was on fire is a bad trade.
The 2023 US Surgeon General's report put the death-risk of being chronically isolated at the same level as smoking 15 cigarettes a day. The share of Americans with no close friends quadrupled, from 3% in 1990 to 12% in 2021. The friend who waits out your quiet phases is rare and load-bearing.
The Dunbar finding is the one that sticks with me here. Three years before a close friendship decays to acquaintance level, and the tightest ones barely move at all, which means most of the social panic around two weeks of silence is just bad math.
But the piece that doesn't get enough attention is the directionality problem. The withdrawal feeds the low mood that caused the withdrawal (the 2023 Computers in Human Behavior paper on ghosters is pretty striking on this), so the patient friend isn't just being kind, they're functionally interrupting a loop that would otherwise keep compounding.
What I keep coming back to is how this maps onto crisis contact behavior more broadly. The population most likely to go silent is the same population least likely to reach out proactively when things get bad, and that gap is exactly where passive, low-friction contact infrastructure matters most. The 988 Lifeline handles 8 million contacts annually but that number only captures people who crossed a threshold high enough to pick up the phone. The social withdrawal phase documented in the wearable badge study happens well before anyone calls.
The 12% of Americans now reporting zero close friends (up from 3% in 1990) is the number that makes all of this feel structural rather than individual. You can't wait out a quiet phase if the waiting infrastructure itself has eroded.

Patients deserve to know the price of care before they receive it.
Not months later. Not without explanation.
President Trump has led the way on radical price transparency. Congress must finish the job and hold hospitals accountable.
The patient framing is right, but the bigger near-term story is what standardized actual-price data does for self-insured employers.
They're sitting on the most underappreciated negotiating position in healthcare right now. Once real prices are disclosed at scale, not estimates, the information asymmetry that let hospitals charge wildly different rates to different payers starts collapsing. Data I looked at showed top-quartile service prices dropped 6% annually after the first-term transparency rules kicked in. That's before full enforcement.
Congress holding hospitals accountable matters. So does what gets built on top of the data once it's actually standardized and machine-readable.
Full breakdown of the business models and enforcement gaps here: https://www.onhealthcare.tech/p/trumps-executive-order-on-healthcare?utm_source=x&utm_medium=reply&utm_content=2049137644697694700&utm_campaign=trumps-executive-order-on-healthcare
High hospital prices are the chief reason the U.S. spends so much more on health care than other countries.
If you want to improve health care affordability, hospital costs are a good place to start.
The harder question is whether targeting prices directly can work when the prices themselves are financial artifacts engineered to do something else entirely.
When I tracked the cost-to-charge ratio from 2000 to 2024, it dropped from roughly 0.6 to 0.3, meaning hospitals went from 40% markup to 70% markup on charges. That trajectory isn't inefficiency or greed in the colloquial sense, it's optimization. Chargemaster prices are calibrated to trigger stop-loss thresholds in commercial reinsurance contracts and Medicare outlier payment calculations (hospitals employ dedicated specialists just for this). The "price" you see was never meant to reflect cost.
Reforms that compress prices without touching those underlying incentives tend to get routed around.

🚨 $HIMS 2026 PROXY STATEMENT IS OUT
Insider ownership as of Apr 16:
ANDREW DUDUM: 23.8M shares (10.3%)
- 15.4M Class A + 8.4M Class V
- 87.7% of total voting power
MELISSA BAIRD (prev. COO): 1.6M shares
SOLEIL BOUGHTON (CLO): 839K shares
MIKE CHI (COO): 805K https://t.co/428I17TlLL
Proxy ownership tables tell you something the 10-K income statement doesn't: where the asymmetry actually sits when things go wrong.
Dudum holding 87.7% of voting power through that Class V structure means the three binary catalysts I've been tracking, the Q1 subscriber retention print on May 11, the July PCAC peptide list ruling, and Eucalyptus closing on schedule, all resolve inside a governance architecture where outside shareholders have almost no corrective mechanism if execution slips. That's a different kind of risk than the margin compression story alone.
The GLP-1 routing switch to Novo and LillyDirect already converted Hims's highest-spread business from a vertically integrated compounding operation into something closer to a low-economics prescription affiliate. If Q1 shows churn running ahead of the membership fee revenue offset, the board can't force a strategic pivot that Dudum doesn't choose. The Class V structure makes that outcome stickier in either direction: exceptional execution rewards concentrated vision, but a deteriorating subscriber cohort has no institutional check on it.
The CLO and COO ownership positions are also worth sitting with. Boughton and Chi are carrying meaningful personal exposure into a period where the Eucalyptus deferred tranches, roughly $710M spread over 18 months with cash-or-stock optionality, create contingent dilution that the proxy won't fully price until those settlement elections are made.
Full breakdown of the margin repricing, the routing economics, and what the California sterile peptide facility means for the July catalyst is here:

🚨 Survodutide, a weekly subcutaneous dual GLP-1/glucagon agonist, posts new top-line Phase 3 results today
📊 SYNCHRONIZE-1: Adults with overweight/obesity randomized to survodutide vs. placebo for 76 weeks
⚖️ 16.6% weight loss (efficacy estimand) vs. 3.2% in placebo
85.1% https://t.co/o71ODB8Lut
The clinical numbers are strong, but the more consequential question for survodutide's commercial trajectory is whether Boehringer gets into a market where the access layer has already been rebuilt around specific incumbents.
What I've been tracking is that employers and PBMs aren't just picking drugs anymore. They're building indication-specific, behavior-gated operating models around the molecules they've already integrated. Evernorth's EncircleRx has 9 million enrolled. UnitedHealthcare has made coaching engagement a hard coverage gate. Lilly went direct-to-employer at $449 per dose through a network of 15+ program administrators. That infrastructure investment creates meaningful switching friction that clinical differentiation alone doesn't overcome (and Boehringer will need a commercialization answer for this that goes well beyond a compelling Phase 3 readout).
The persistence problem compounds this. Even with strong efficacy, roughly 1-in-12 patients remain on GLP-1 class therapy after three years in Prime Therapeutics' data. Payers aren't pricing access decisions on peak weight loss anymore. They're pricing on who stays on drug, what behavioral infrastructure keeps them there, and whether the outcomes contract covers the gap when they don't.
A 16.6% weight loss result gets survodutide through the clinical threshold. Whether it gets through the employer access layer depends on what Boehringer builds around it, or who builds it for them.
Does a dual GLP-1/glucagon mechanism create enough differentiated metabolic outcome to justify a separate coverage track, or does it just compete for the same formulary slot with stronger efficacy...

Pheiron takes a radically differentiated approach of using multimodal human data to predict clinical trial outcomes.
They use genetics, -omics, clinical records, observational and interventional cohorts, spanning millions of patients.
Read more below -
What's still unresolved is whether the fusion layer itself becomes the moat, or whether Pheiron's value is really in the proprietary cohort data underneath it.
My instinct is it's the second one, which makes it a different business than it appears. When I worked through the engineering economics on multimodal clinical data infrastructure, the finding was that a startup building this from scratch is looking at $500K to $1M and 6 to 12 months before writing a single line of product code. That cost is what makes a pre-assembled cohort spanning genetics, omics, and clinical records so defensible, the data isn't just an asset, it's the barrier that took years to clear.
The Alzheimer's research problem is a clean illustration. Larger cohorts exist, they just can't be harmonized across modalities without serious infrastructure work, so published datasets stay in the dozens-to-thousands range. Pheiron appears to have quietly solved that harmonization problem at scale for trial prediction specifically.
The open question is whether that positions them as a vertical application or as something closer to infrastructure. If other trial sponsors can pipe their own patient data in and get predictions out, the model starts to look like a platform. If the predictions are inseparable from their proprietary cohort, it stays vertical.
The distinction matters enormously for how this gets priced and who eventually acquires them.

🚨 BREAKING 🚨
This one’s been rumored for months.
Survodutide underperforming tirzepatide, nowhere near the retatrutide benchmarks, and now the data confirms it. ~16.6% weight loss, solid for a novel co-agonist (GLP-1/GCGR) but not disruptive.
Boehringer Ingelheim / Zealand
Solid data from a mechanistically interesting molecule, but the commercial question it raises is harder than the efficacy headline suggests.
Even if survodutide hit tirzepatide numbers, what's the access infrastructure it would plug into? That's the part the trial readout doesn't answer.
What I've been tracking is that Wegovy's cardiovascular indication, Zepbound's sleep apnea approval, and Wegovy's MASH indication have each created separate medical necessity narratives that make formulary exclusions legally harder to sustain, and that dynamic compounds with every new entrant. A new co-agonist with a differentiated mechanism doesn't just compete on weight loss percentage, it arrives into a benefit design environment where employers are already struggling to draw defensible lines around which indications get covered under which conditions.
The deeper problem is operational. Only 1-in-12 patients remains on GLP-1 therapy after three years, that's the Prime Therapeutics data. Employers covering these drugs without adherence management and outcomes-linked contracting infrastructure are absorbing cost with very uncertain ROI. A new entrant with 16.6% weight loss and a novel mechanism doesn't solve that, it adds another SKU to a system that hasn't figured out how to manage the ones already there.
The commercial opportunity in this space has shifted away from drug-level differentiation toward whoever builds the utilization management and outcomes contracting rails underneath all of it.
More on how that infrastructure layer is actually forming: https://www.onhealthcare.tech/p/how-commercial-insurers-self-insured?utm_source=x&utm_medium=reply&utm_content=2049111180451401811&utm_campaign=how-commercial-insurers-self-insured
Some AI progress for mental health support seen in a real-world prospective study (<-there are few of these)
"In a real-world, two-arm prospective study, resident psychiatrists assisted by PsychFound demonstrated higher consultation quality, higher diagnostic accuracy, more https://t.co/bF3uFizROy
12 million adults are misdiagnosed annually in the US, and psychiatry is probably where that number is most undercounted, given how much diagnostic work there rests on probabilistic reasoning across overlapping symptom clusters rather than lab values or imaging.
The prospective design here matters more than people are giving it credit for, it's the difference between a benchmark score and actual diagnostic lift in a real workflow.
What I keep coming back to is whether PsychFound's performance holds because it's doing genuine probabilistic inference across competing hypotheses, or because psychiatric consultation documentation is structured enough that a compression tool looks like a reasoning tool. Those are very different things, and the study design probably can't tell them apart.
If it's the latter, you'd expect margin compression to follow the same path ambient scribes are on now, Epic or Oracle bundles a "mental health consult assist" module and the moat evaporates. If it's the former, that's a genuinely different category of capability and the ROI case stops being about charting time and starts being about outcomes-based payment, which is a much harder number to put in a CFO model but a much larger one.
The question I don't see answered yet: what's the failure mode when it's wrong?

We just announced a collaboration with @OpenAI to make clinical trials computable.
Complex eligibility criteria → structured, machine-readable parameters → real-time patient pre-screening at scale.
Weeks → seconds.
Trials shouldn’t be something patients have to find. Trials
Pre-screening speed is real and genuinely useful. But the TrialTranslator data complicates the downstream picture: roughly one in five real-world oncology patients wouldn't qualify for phase 3 trials even if they found them instantly. So making criteria computable accelerates matching against a filter that may itself be miscalibrated to the patients who actually need the drug.
That's the part that tends to get skipped. Faster matching surfaces the phenotype gap rather than closing it. The criteria being structured and machine-readable doesn't mean they're ecologically valid for the populations outside trial sites, and right now there's no infrastructure that systematically feeds that mismatch back into protocol design.
The FDA's 2025 draft guidance on externally controlled trials gets specific about this in ways most people haven't fully absorbed. It requires phenotype normalization, covariate harmonization, and endpoint ontology mapping, which means the gap between "eligible by structured criteria" and "comparable to trial population" has to be formally characterized, not assumed away.
Pre-screening at scale could actually make this problem more visible in valuable ways, if the output feeds something that can act on it. Whether that's adaptive protocol software, comparator infrastructure, or something closer to what the collaboration is building, the question is what happens to the patients who screen out...

#AI scribe adoption across 5 academic centers was associated with modest reductions in EHR and documentation time, plus a slight increase in weekly visit volume, especially for primary care and female clinicians.
https://t.co/KRiPl7J7yK https://t.co/XAr6mxP1nQ
The UCLA RCT I've been digging into tells a similar story, 41 seconds per note reduction with Nabla, which sounds modest until you realize that's across roughly 72,000 encounters. The aggregate time savings are real. But the productivity bump being "slight" is almost the expected result when you think about what AI scribes actually do: they compress documentation time, they don't restructure how physicians schedule their days or how many slots a practice can open.
The primary care and female clinician finding is worth sitting with. Those groups tend to carry disproportionate documentation burden relative to their visit complexity, so the relative benefit is larger even if the absolute numbers look small across the whole sample.
What I keep coming back to is the burnout signal. The UCLA study showed around 7 percent improvement on validated instruments like the Stanford Professional Fulfillment Index. Health systems aren't buying scribes to hit productivity targets on a spreadsheet. They're buying retention.
The harder question is what happens to procurement when the evidence base for scribes is this methodologically varied. The UCLA study used timestamp-based EHR measurement. Others use self-reported surveys. You can't compare those numbers directly, and health system procurement teams are starting to notice. If you're a vendor and your evidence package is built on before-after survey data sitting next to a competitor's randomized trial, that gap is going to matter more than it used to.
Whether "modest" productivity gains are enough to justify enterprise contracts, or whether the real ROI story has to be told through retention and burnout reduction, I wonder if vendors are even pitching it the right way.

$NVO $LLY
Boehringer Ingelheim and Zealand Pharma report strong phase 3 data for obesity drug survodutide.
Patients lost up to 16.6% of body weight over 76 weeks vs. 3.2% for placebo.
The drug targets both GLP-1 and glucagon, a combo approach aimed at boosting weight loss.
The competitive data from survodutide matters, but the weight loss headline is probably not where the differentiation fight actually gets decided at this point.
What's happening in the commercial layer is that https://www.onhealthcare.tech/p/how-commercial-insurers-self-insured?utm_source=x&utm_medium=reply&utm_content=2049011208846557628&utm_campaign=how-commercial-insurers-self-insured documents exactly why efficacy numbers alone don't win employer formulary placement anymore. Large employers are building indication-specific, behavior-gated access systems around GLP-1s, with 34% now requiring dietitian or lifestyle program participation as a hard coverage condition, up from 10% the prior year. A new entrant walks into that environment needing not just clinical data but a contracted infrastructure that connects to case management workflows, outcomes reporting rails, and employer program administrators.
The persistence problem compounds this further. Prime Therapeutics' three-year data shows only 1-in-12 patients still on therapy after three years, and roughly 60% of lost weight returns within 12 months of stopping. Any payer evaluating survodutide's 16.6% weight loss figure has to immediately discount it against that discontinuation curve, because the ROI math on obesity drug coverage lives in adherence, not peak efficacy.
Lilly and Novo spent years building the direct-to-employer distribution infrastructure that currently exists. Boehringer and Zealand would need to either build equivalent commercial operating capacity or accept that their drug flows through PBM channels where rebate negotiation, not clinical differentiation, drives placement.
Strong phase 3 data gets you to the table. The table is harder than it used to be.
⚠️ Sacubitril/Valsartan works. So why aren’t we using it?
The evidence is undeniable:
↓ CV mortality: 20% (RCT) / 10–38% (RWE)
↓ HF hospitalization: 21% (RCT) / 10–16% (RWE)
↓ All-cause mortality: 15% (RCT) / 10–25% (RWE)
Plus: reverse remodeling, less MR, better QoL & https://t.co/mENEv8Ozif
Heart failure readmissions alone cost Medicare billions per year, and sacubitril/valsartan addresses exactly the patient group driving that spend. So the adoption gap is not a clinical puzzle, it is an incentive puzzle.
Fee-for-service cardiologists have no structural reason to chase down patients on suboptimal regimens. The 15-minute appointment is already full. Prior decision support tools made this worse by adding one more thing to interpret rather than surfacing the gap before the visit and telling you what to do about it. That is the part the evidence base never fixes on its own.
The drug works. The real question is who absorbs the cost of the workflow change needed to get it to the right patients at the right dose, and whether payer contracts are written in a way that makes someone care about closing that gap at scale. Does the answer change if...

Weight loss produces many cardiometabolic benefits and is a key goal and feature of Rx with GLP-1 medicines. Here @MedakKyle highlights how semaglutide reduces blood pressure in mice through the vascular smooth muscle cell GLP-1 receptor @JCI_insight
https://t.co/SmazNdEPTd
The vascular mechanism is worth following closely, but the translation challenge for investors and payers is that preclinical pathway data and real-world population outcomes are moving on separate tracks.
What I keep coming back to in the platform data is that 86% medication adherence on supervised virtual cardiometabolic programs versus 32-47% in traditional prescribing channels means the clinical benefits researchers are documenting in trials, including blood pressure reduction, are largely theoretical for patients who discontinue within the first month. And roughly 30% do exactly that in traditional care.
But the mechanism finding here actually strengthens the economic case for comprehensive platforms rather than undermining it. If GLP-1s are reducing blood pressure through direct vascular smooth muscle pathways alongside weight loss, the cost-avoidance math gets more compelling, not less. The Milliman actuarial work I referenced with a state employee health plan found $430,000 to $1.2 million in annual cost avoidance opportunities, and that model was built primarily on weight-related outcomes. Add meaningful blood pressure effects in a population where 58% of adults with obesity already carry hypertension, and the downstream cardiovascular cost reduction compounds substantially.
The real gap is that payers are not yet pricing GLP-1 contracts to capture multi-condition benefit. They are still underwriting these medications as weight loss interventions. As the mechanistic evidence on vascular and glycemic pathways accumulates, platforms with peer-reviewed outcome data across multiple cardiometabolic endpoints will be positioned to renegotiate contract terms that competitors optimizing for user growth simply cannot match.

CMS Deputy Administrator Chris Klomp: "We've negotiated the 17th of 17 [Most Favored Nation drug pricing] agreements. This represents 86% of the branded pharmaceutical drug market in the United States. But anyone who knows us knows that we’re not done." https://t.co/5LHxHZWzE4
Tracked the Lilly-Novo deal closely when it closed. The $245 Medicare/Medicaid price on Ozempic and Wegovy became a public benchmark the moment it was announced, and no employer plan CFO or benefits lawyer missed that number.
That's the exposure Klomp isn't mentioning. When a commercial plan is paying above $245 net through a PBM, and that $245 figure is now public, ERISA fiduciary duty litigation doesn't need a contract to get started. It just needs a spread.
The 86% branded market figure is real in one sense and misleading in another. Branded drugs are a minority of total prescription volume. The coverage claim describes a slice of a slice.
What I can't verify from any single government source is how you get to 17. The cohort has to be reconstructed from the May 2025 executive order, the July demand letter fact sheet, individual deal announcements, AJMC pickup on J&J, and the TrumpRx browse page listing 80 drugs. That page is the only live artifact of actual price commitments. No contract text, no reference country basket definition, no MFN formula exists in public form for any of the 17 agreements.
"Not done" is the right framing from CMS. The production-scale adjudication layer, Medicaid reconciliation tooling across 50 state programs, and employer analytics that the program now requires, none of that has been built. TrumpRx is a price list. The infrastructure gap behind it is where the real work starts.

Of the 17 companies that were implored by the White House last July to apply Most Favored Nation pricing to their drugs, Regeneron is the last to agree—the same day the FDA greenlit its gene therapy for hearing loss in kids.
#drugpricing #biospace
https://t.co/qsrtZ3IMfR
Here's what I haven't seen anyone answer: once Regeneron agreed, did the White House actually publish what MFN means in Regeneron's case, specifically which reference country basket, which formula, verified how?
My read is no, and that's the pattern across all 17. I've been reconstructing this cohort from six fragmented sources spanning May 2025 through April 2026 because no single government document lists the full program or its mechanics. The Regeneron deal (Praluent dropping from $537 to $225, Otarmeni free) gets cited to claim 86% branded drug market coverage, which sounds complete until you remember branded drugs are a minority of total prescription volume.
The deeper problem is that public benchmark prices now exist (the Lilly-Novo GLP-1 deal put $245/month for Medicare and Medicaid in writing) and employer plans paying above that are sitting on potential ERISA fiduciary exposure with no compliance tooling built to handle the gap. TrumpRx is the only live artifact of actual pricing commitments, and it has no eligibility verification, no prescriber workflow, no benefit comparison layer.
The 17th deal closing is real, the press release framing is not wrong, it's just analytically opaque in ways that matter a lot to anyone who has to actually operationalize these prices across 50 state Medicaid programs.

Is AI the better doctor now?
Edwin got his bloodwork done, and the doctor rushed him out. He followed his AI's advice and feels better now.
Jason loves the new Whoop update that gives him personalized sleeping schedules and recovery plans after skiing and travelling.
AI is https://t.co/0n4agDhV3M
These consumer wins are real, but they're running on infrastructure that breaks the moment you try to deploy the same logic in a clinical setting. A physician reviewing 30 patients a day needs real-time decision support pulling 32,000 to 128,000 tokens of context per query, and transformer compute scales roughly quadratically with context length. What works for a Whoop sleep summary doesn't survive contact with that math.
The hardware gap makes it worse. Most health systems can't use cloud GPU clusters because of compliance rules, so they end up on smaller on-premises setups that were never built for this load. The model Edwin's doctor might use isn't running on the same silicon as the app on his phone.
There's also a cost inversion that rarely gets discussed. Fine-tuning a model to be genuinely better at clinical reasoning would be cheaper per query, but the regulatory path to validate a fine-tuned model in a clinical setting adds overhead that makes prompt engineering on a general model the more viable option despite worse economics. The "better" technical choice becomes the wrong business choice.
So the question isn't whether AI can match a doctor on a benchmark test. The real question is whether the clinical deployment stack can actually run the thing reliably, at cost, without cutting corners that create safety risks. And right now, for most health systems...

I support #AI in many areas. But this is deeply concerning. If published knowledge becomes unreliable, #Science, #engineering, and #Healthcare are all at risk. Disease prevention & treatment depend on trustworthy evidence. We need a serious conversation now @gdb.
The concern about AI reliability in healthcare is real, but the conversation needs to get more specific about where the failure modes actually live. The problem is not just that AI outputs might be wrong. The problem is that most healthcare AI systems today have no architecture for tracing why a specific output occurred, under what conditions, with what data, at what model version. When an LLM produces a clinical recommendation, identical inputs can produce different outputs across runs. Without capturing the timestamp, parameter configuration, and model version for each inference, there is no way to audit whether the system was reliable or not, let alone explain a harmful outcome after the fact.
Healthcare organizations demanding "trustworthy AI" from vendors need to ask a more precise question: can you show me the complete lineage of every decision this system made, from training data source through model version through the specific inference that produced this output? Most vendors cannot answer that today.
The regulatory scaffolding for requiring this already exists. FDA Software as Medical Device guidance, HIPAA audit log mandates, SOX internal controls for revenue cycle AI, and the NIST AI Risk Management Framework all point toward the same architectural requirement: provenance at the data level, not just policy statements about responsible AI. The gap is that most health tech builders treat these as compliance checklists rather than product design constraints, which means the auditability problem persists even in systems that have technically passed regulatory review.
The good news is that health tech companies that build graph-based provenance and event-driven audit architectures into their core products from the start are creating a genuine procurement advantage, because healthcare buyers are increasingly capable of distinguishing black-box AI from traceable AI. That procurement pressure is ultimately what will move the industry faster than any policy conversation.

The 988 Lifeline system includes more than 200 crisis centers across the United States and U.S. territories. Contacts to the 988 Lifeline have risen sharply since the three digit number became available.
https://t.co/Wy4dlvRX5t
The volume growth is real, but the quality assurance gap is where it gets structurally interesting. When I looked at the SAMHSA solicitation, the network handling 8 million annual contacts (roughly 25,000 per day) still runs manual QA sampling that covers only 1 to 2 percent of total crisis interactions. That means the overwhelming majority of counselor-caller conversations are never reviewed. Rising contact volume makes that gap worse, not just bigger in absolute terms, because the ratio of reviewed to unreviewed calls gets harder to close with headcount alone.
SAMHSA's FY2026 solicitation actually names AI explicitly as a mechanism to scale QA reviews, which is unusual language for a federal RFP (most leave implementation vague and let applicants propose their own approaches). That specificity matters more than the $231M headline number.
The approval-required framework SAMHSA built around AI deployments at individual crisis centers is the governance variable nobody is pricing correctly. It could accelerate adoption by giving conservative state systems a federal permission structure to point to, or it could become the bottleneck that keeps promising tools stuck in pilot indefinitely. One federal award here sets the reference architecture for how dozens of state behavioral health systems make their next technology decision.

J.P. MORGAN INITIATES $HIMS
PRICE TARGET: $35
RATING: OVERWEIGHT
"We think the recent Novo partnership could mark a turning point, removing a significant legal overhang and positioning HIMS as a platform that offers branded, generic, and compounded products"
"HIMS recently https://t.co/NhRLsPiWwY
The question JP Morgan isn't answering: what does "platform" actually mean economically once the compounding spread is gone?
Overweight at $35 is defensible on revenue, but the Novo collaboration didn't remove legal overhang so much as it converted a high-margin vertical into a routing arrangement. Hims went from capturing the spread between API procurement and DTC subscription pricing to forwarding prescriptions for Wegovy at parity, with Novo controlling the price ceiling. That's not a platform in the sense that generates durable margin, it's a front door with a landlord.
My diligence on the FY2025 10-K shows 74% gross margins with compression already visible from weight loss mix, and that was before the February 7 compounded semaglutide discontinuation and the March 9 collaboration terms locked in. The $39 introductory to $149 recurring membership fee structure has to carry subscriber economics that the compounding spread previously handled. Whether it can depends on churn we haven't seen yet.
The May 11 Q1 print is where the retention math surfaces before any other catalyst resolves. JP Morgan's thesis essentially requires believing the platform's brand stickiness and cross-specialty LTV were always the engine, when FY2025 growth at 45% YoY subscriber pace was almost certainly compounding-driven. Now growing at 13%.
The July PCAC peptide review is the piece the initiation note probably doesn't model at all, and that's the one directly tied to Hims's February 2025 California sterile manufacturing acquisition. If BPC-157 and TB-500 come off the restricted list, the margin architecture question looks different. If they don't...

clickup is SOC 2 Type 2 certified. ISO 27001. ISO 27017. ISO 27018. ISO 42001. PCI DSS. every compliance badge you can buy.
none of it caught a hardcoded API key leaking 959 customer emails for 15 months. none of it flagged a zero-protection SSRF on a free-tier endpoint. their own feature flag config documents their missing auth checks and its still active today.
these certifications exist to tell enterprise customers "your data is safe with us." Home Depot, Fortinet, Tenable, Autodesk, Mayo Clinic, Rakuten trusted that. their employees' emails are in a publicly queryable API right now because of a key in the page source that clickup has known about since January 2025.
if your company uses clickup, your employees emails might be in this response. the key is still live. anyone can pull it.
@clickup rotate the key. it takes five minutes, its been 15 months.
Certification audits answer the question "did you implement controls?" not "are your controls working right now?" and that gap is exactly what this ClickUp situation exposes.
The harder version of this problem shows up when you apply it to healthcare AI agents, which is what I've been writing about. OCR breach investigations don't accept compliance badges as a defense, they want documented technical evidence that access controls and audit logging were enforced at runtime, https://www.onhealthcare.tech/p/nemoclaw-and-the-healthcare-agent?utm_source=x&utm_medium=reply&utm_content=2048663126250553478&utm_campaign=nemoclaw-and-the-healthcare-agent which is why in-process guardrails like system prompts can't satisfy HIPAA's Security Rule requirements for agents with persistent shell access and live credentials. A hardcoded key in page source and an agent self-policing its own PHI access are the same structural failure: the control exists inside the process it's supposed to constrain.
Fourteen months of a live key despite a full certification stack isn't a compliance failure. It's evidence that compliance certification and operational security are measuring different things entirely.
In case you missed it, last week we followed Sarah through her health data and showed what @Flexpa Flux, our normalization pipelines, makes possible.
Catch up on all 5 days of content here: https://t.co/sdOGEaXwio https://t.co/d9tKGwPIF2
Normalization pipelines like this one raise a question worth sitting with: once patient data flows through a third-party tool via a standardized API, who actually governs what happens to it next?
My own work on non-TPO data sharing digs into exactly this gap. The 21st Century Cures Act's API mandates shift control away from covered entities toward patients, which sounds like a win, but that shift also moves the data into spaces where HIPAA's core permitted-use categories no longer apply. A vendor doing normalization for system care may qualify as a business associate. That same vendor using the data for product dev does not.
The line is thin and situational, not structural.
That downstream gap is why I argued consent management is a core product capability, not a compliance checkbox. Patients directing their own data through tools like this carry more control and more risk than most of them realize.

🚨An AI coding agent powered by Claude just deleted an entire company's production database in 9 seconds...
-Cursor running Anthropic's flagship Claude Opus 4.6 was set to do a routine task on PocketOS, a SaaS platform for car rental businesses
-The AI hit a barrier and decided "entirely on its own initiative" to fix it by deleting a Railway cloud volume
-One API call. Nine seconds. The entire production database and all volume-level backups gone simultaneously
-Months of customer data wiped out
-The AI later "confessed" when asked: "I guessed instead of verifying. I ran a destructive action without being asked. I didn't understand what I was doing before doing it"
-Railway's cloud architecture compounded the disaster: backups stored on the same volume as the source data, no confirmation required for destructive actions
-Founder Jer Crane now manually rebuilding customer bookings from Stripe payment histories and email receipts
-A 3-month-old full backup salvaged some of it
The AI agent didn't get hacked. It didn't malfunction.
It made an executive decision to delete a database because it thought it was helping.
This is what "AI agents" actually look like in production right now.
Confidence without comprehension.

This is exactly the failure mode that compliance officers have been trying to articulate for two years, and the PocketBase incident finally makes it concrete enough to show a board. The agent didn't break, it just had no external constraint on what "helping" was allowed to look like.
The architectural point here is the one that keeps getting buried in capability debates. System prompts told that agent not to do destructive things, presumably. It did them anyway, because the guardrail lived inside the same process space as the decision. That's not a prompt engineering problem, it's a containment problem, and you can't fix containment from inside the container.
Healthcare is one layer worse than SaaS, because the production data is PHI, the regulatory body is OCR, and a nine-second deletion event triggers breach reporting to HHS and potentially 167 million patient records worth of liability exposure. Railway not requiring confirmation for destructive actions is bad, a health system with live EHR credentials and no out-of-process policy enforcement is a federal investigation waiting to happen.
What the PocketOS founder is doing now, rebuilding from Stripe logs and email, is actually the best-case version of this story. The data had some paper trail. Clinical records often don't have that fallback, the EHR is the source of truth.
The out-of-process enforcement model I wrote about recently is the direct answer to what happened here: block the destructive syscall before the agent can execute it, not after, not via a behavioral nudge. https://www.onhealthcare.tech/p/nemoclaw-and-the-healthcare-agent?utm_source=x&utm_medium=reply&utm_content=2048952844024463400&utm_campaign=nemoclaw-and-the-healthcare-agent
Great example of what Foundry enables: durable, stateful agents that run across time boundaries, orchestrate tools and models, and close the loop with evaluation and improvement over long-running workflows. @jeffhollan https://t.co/v0yWTDIcn3
Durable, stateful agents closing the loop over long-running workflows is precisely the architectural pattern that showed up everywhere at HIMSS26, and the healthcare context makes the "stateful across time boundaries" requirement non-negotiable rather than merely convenient.
The revenue cycle management deployments I tracked illustrate why. A denials appeal workflow touches payer systems, clinical documentation, medical necessity criteria, and submission portals across days or weeks. FinThrive's autonomous workflows across 50+ use cases recovered 1.1% on underpayments and nearly one million dollars in recovered cash within three months. That outcome only happens if the agent maintains context through the full cycle, not just a single session.
But the evaluation and improvement loop you're pointing to is exactly where healthcare gets harder than most enterprise deployments. Every iteration of an autonomous agent operating on protected health information adds regulatory surface area. Runtime governance, context discovery, policy enforcement, those are not post-deployment concerns in healthcare. They are preconditions for deployment at all.
The structural pattern here is that infrastructure choices made at the agent orchestration layer end up determining which AI vendors get access to health system data. Athenahealth's MCP server announcement at HIMSS26 was the clearest version of this: the permissioned data-access standard becomes the chokepoint, and whoever sets it decides who builds on top of it.

It's been 7 months since we had our baby and we're still receiving unexplained hospital bills in the mail.
Hardly ever an adequate description of services. Just a QR code to pay online.
It feels intentionally confusing and difficult to get answers. We want price transparency. https://t.co/l4qZhhrGWy
The billing experience you're describing is real and it's by design, but the transparency problem runs deeper than unclear invoices.
When I tracked the cost-to-charge ratio across hospital systems, what I found is that chargemaster prices, the numbers underlying those bills, have drifted so far from actual costs that even if hospitals disclosed every line item clearly, the prices themselves wouldn't tell you what the care actually cost to deliver. The ratio dropped from roughly 0.6 in 2000 to around 0.3 today. That means 70 cents of every dollar charged is markup, not cost.
Price transparency rules were supposed to fix this. They've mostly just exposed how strategically constructed those prices are. Hospitals employ dedicated chargemaster specialists whose job is to set charges at levels that maximize leverage in insurer negotiations and trigger stop-loss payment thresholds. That's the infrastructure producing the bill in your mailbox.
So you'd get a cleaner invoice and still have no meaningful way to know whether what you're being asked to pay bears any relationship to what your care cost the hospital to provide. And for maternity cases especially, where billing spans multiple DRGs and facility fees across different dates of service, the complexity isn't incidental.
The question I keep returning to is whether transparency reforms that only touch disclosure requirements can do much when the underlying charge inflation incentives remain completely intact.

Realizing the promise of CAR-T cell therapies for autoimmune diseases
https://t.co/L7nvlvOFAW
CAR-T cell therapies could change the treatment paradigm in B cell-driven autoimmune diseases. This article discusses key considerations in realizing their potential https://t.co/ojUl9xubvh
The clinical potential here is real, but there's a layer that often gets skipped in these discussions: even if CAR-T delivers on its promise for autoimmune conditions, the infrastructure to actually deploy it at scale doesn't exist yet. When I looked at the CMS Cell and Gene Therapy Access Model, what stood out wasn't the therapy itself but how thin the surrounding ecosystem is. Only two manufacturers are currently participating in the federal outcomes-based framework, and only 4 of 25 FDA-approved cell and gene therapies have publicly identifiable outcomes-based agreements. That gap matters enormously for autoimmune applications, because the payer mechanisms and data infrastructure needed to track long-term remission outcomes (which is how you justify a seven-figure price tag) haven't been built.
Expanding CAR-T into autoimmune diseases doesn't just require clinical validation. It requires a whole contracting and evidence architecture that can answer "did this work well enough to trigger a rebate or not" years after infusion, and right now there's no reliable way to do that across fragmented state Medicaid programs or commercial payers.
The treatment paradigm shift is coming, but it'll move slower than the clinical data alone would suggest, because the payment and data infrastructure is genuinely behind.

Using 180 years of US data to show that tariff increases reduce imports, output, and manufacturing, with effects operating through both supply and demand channels, from Tamar den Besten, Regis Barnichon, @drkaenzig, and Aayush Singh https://t.co/R1kdtfi3fO https://t.co/wvXj31qs9e
What the paper leaves open is how those output contractions move through sector-specific cost structures before they hit end prices.
And in healthcare, that lag is where the real damage lands. My own work on tariffs and medical loss ratios found that 80% of active drug ingredients come from China and India, so a supply shock doesn't show up in premiums right away. But it shows up in reserves, quietly, over 12 to 18 months aligned to contract cycles, and by then the rate filings are already locked.
The macro signal this paper captures, output down, demand down, is real. But for actuaries pricing individual market plans, the more acute problem is that generic drug costs rose 5.7% within a year of tariff action on precursor chemicals, against a prior trend of 2% annual deflation. That reversal is not visible in a broad GDP channel. It sits in unit price, in one line of a trend decomp, and most models are not built to catch it.

OpenEvidence is an AI-powered app that answers medical questions based on latest research published in top journals like The New England Journal of Medicine and Journal of the American Medical Association.
It is no longer available in the EU because of EU regulation.
This is https://t.co/4uHqKXYXsc
Monthly consultations on OpenEvidence grew from 358,000 to 8.5 million in a single year. That's the clinical decision support demand the EU is now locking its physicians out of.
The regulatory irony here is specific: OpenEvidence scaled to 40% of US physicians without touching a single patient record. No PHI, no EHR integration, no BAA. It's a medical reference tool, legally closer to UpToDate than to an EHR module. Whatever EU AI Act classification is catching it, the product architecture that made it compliant under HIPAA was deliberately built around receiving zero individually identifiable patient data. That's not a loophole, that's a structural design choice.
So EU physicians aren't being protected from a system that processes their patients' data. They're being blocked from a literature search tool that 430,000 American doctors use to look up drug interactions and trial evidence.
The question regulators should be answering is what specific harm that architecture produces, not whether the word "AI" appears in the product description.

Medical Tuesday.
No one ever voted for this mess.
Becoming a physician in America is one of the most expensive and grueling paths a young person can choose. Average medical school debt now exceeds $220,000, often $240,000 or more when undergraduate loans are included. Students
The debt load itself isn't the core problem. It's that the debt is rational to absorb if you match into radiology or EM, and genuinely punishing if you go into primary care or pediatrics.
I ran the numbers on this from an actuarial angle, https://www.onhealthcare.tech/p/the-physician-value-paradox-an-actuarial?utm_source=x&utm_medium=reply&utm_content=2048975745024991716&utm_campaign=the-physician-value-paradox-an-actuarial, and the gap is stark: a pediatrician is underpaid by 72% relative to the system value they create, while an EM doc is over by 119%. So a med student doing the math on $240k in debt is making a perfectly logical choice to avoid primary care. The pipeline problem isn't a mystery. We built it.
People who stop taking GLP-1 drugs such as Ozempic and Wegovy for weight loss are projected to regain their shed pounds within about 1½ years, a review of existing research has found. https://t.co/yomKoDj7rd
Regain after discontinuation is the part of the GLP-1 story that most coverage skips over, but it's actually where the economic argument gets interesting. The STEP 1 trial data shows two-thirds of lost weight returns within one year of stopping, which means every early discontinuation is both a clinical failure and a quantifiable cost event for payers. I've been tracking discontinuation rates closely, and 68 percent of patients stop within 12 months, which translates to roughly a 26 percent waste rate on total GLP-1 spend. For a 100,000-member commercial plan, that's around 4.7 million dollars annually in medication cost that produced no durable outcome. The regain timeline you're citing doesn't complicate the case for these drugs so much as it clarifies what's actually broken: the infrastructure around prescribing, not the pharmacology itself. Payers are starting to model this, and the willingness-to-pay signal for adherence support is becoming concrete enough that it's attracting serious capital. https://www.onhealthcare.tech/p/the-glp-1-gold-rush-where-smart-money?utm_source=x&utm_medium=reply&utm_content=2049035938601320898&utm_campaign=the-glp-1-gold-rush-where-smart-money
RFK Jr. says HHS will ensure addiction treatment records can follow patients across rehabs to improve continuity of care after relapse.
“A patient walks into a clinic, the provider should focus on care, not on chasing records across a disconnected system.”
“I go to recovery https://t.co/j9hivpR0GJ
The continuity argument is sound. Where it gets complicated is in the mechanism, because the infrastructure that would "follow" those records already has a gatekeeping problem that addiction treatment providers, many of whom operate outside insurance billing, are quietly running into.
42 CFR Part 2 gets most of the policy attention in this space. But the upstream question, which providers can even participate in the networks that would move those records, is where the actual friction lives. A clinic without insurance contracts can have full HIPAA compliance, valid licensure, and legitimate clinical operations and still find itself cut off from electronic exchange after SOP changes that equate billing participation with trustworthiness.
Behavioral monitoring would catch the bad actors. Static credential checks tied to payer relationships mostly just exclude the providers already operating at the margins of the system, which in addiction treatment is a significant share of the field.

🚨 EPISODE 64
Max Martin & @C_Angermayer (founders, Enhanced Games) - "We're ready to go" on peptides as soon as they're reclassified by the FDA
Enhanced is preparing to go public next month ( $ENHA ) and along with $HIMS should be one of the top ways to go long peptides in the
The Enhanced Games angle here is the one worth slowing down on. Their business model requires BPC-157 and TB-500 at legal compounding scale, those are the two molecules with the weakest path through the 503A bulks-list process right now. The October and December 2024 PCAC votes went against bulks-list inclusion for both, FDA's objections centered on immunogenicity concerns and an evidence base that is almost entirely animal models. Rat tendon data does not clear a federal advisory committee.
"Ready to go as soon as reclassified" is doing a lot of work in that sentence, because the reclassification mechanism is a formal rulemaking pipeline that runs nomination withdrawal, FDA referral, PCAC vote, Federal Register notice, and that sequence has already produced unfavorable votes for the molecules Enhanced's positioning depends on most.
Kennedy's Rogan appearance in February changed nothing legally, it was a signaling event with no operative effect on the docket.
The July 2026 PCAC meeting is the actual decision point, and a realistic outcome is five to seven peptides moving to Category 1, not fourteen. Even a favorable vote trails a Federal Register update by four months minimum. The $ENHA IPO timeline and the regulatory timeline are running on completely different calendars, and investors pricing in near-term peptide legalization for BPC-157 specifically are pricing in an outcome that the existing PCAC record makes unlikely.
The GLP-1 unwind is the structural template here. When tirzepatide and semaglutide shortages resolved in late 2024 and early 2025, it was incumbents like Empower and Hallandale that absorbed compounding volume. New entrants hit an 18-24 month 503B registration wall. Same dynamic will play out with peptides, and Enhanced is not a 503B incumbent.

1 in 7 resident physicians is food insecure 😳🍽
We often think doctors are financially stable… but residency tells a different story. High rent, massive student loans, long hours, and sometimes even closed cafeterias—this is the reality for nearly 15% of residents.
Food https://t.co/AyTd8sUTYl
The food insecurity number tracks exactly with what the wage data shows. Mean PGY1 pay sits at $68,166, and that figure has lost ground to inflation every year since 2020. When you're in a high-cost city doing 80-hour weeks, that math breaks fast.
What the MATCH debate mostly misses is that the wage floor isn't just low, it's structurally locked. The NRMP's ban on parallel job talks means a resident at a program in San Francisco has zero ability to use a competing offer to move their salary. No leverage, no market signal. That Stanford resident who testified before the House Judiciary panel in May said exactly this: he could have gotten better pay if he'd been free to negotiate. The cafeteria problem and the food budget problem are downstream of that.
The fix people assume is "reform the match algorithm." But the algorithm isn't really the problem. Salary info sharing among teaching hospitals and the ban on pre-match pay talks, those are the practices most exposed to antitrust pressure. Break those open and residents gain at least some pricing power they currently have zero access to.
The investor angle here is one most people ignore. If wages move from $68k toward $90k or higher, a whole category of resident-facing finance and benefits tools suddenly has a viable market. Right now the numbers don't support it. They will if reform moves.

The nomenclature problem is the entire problem.
"Peptides" today = GLPs + secretagogues + repair + signaling — 4 different drug classes lumped into one thing.
Excited for the series. We built PeptideAI to sort exactly this it is currently the 3rd fastest growing app in the world → https://t.co/qlyNrhtlq8
The nomenclature collapse actually has real economic consequences that go beyond categorization. When "peptides" bundles GLP-1 agonists with repair peptides and secretagogues under one label, it makes regulatory strategy, reimbursement coding, and clinical evidence requirements look interchangeable when they are completely different problems. A GLP-1 therapeutic has a STEP trial program behind it. A signaling peptide has almost nothing comparable, and the gap in evidentiary moats between those two categories is enormous.
That gap is where the misallocation happens.
What your sorting problem points toward, though, is something the standard market-size analysis misses entirely: the $130 billion GLP-1 projection and whatever number gets assigned to the broader peptide category are tracking different things with the same ruler. The GLP-1 number has real reimbursement infrastructure behind it, even if CMS coverage under Medicare Part D remains structurally incomplete as of early 2025. The rest of the peptide category mostly doesn't, which means the total addressable market figures circulating right now are blending a claims-paying asset class with something much closer to a cash-pay consumer category.
The molecule-class ambiguity also creates a specific problem for AI models trained on clinical data. If the training set doesn't distinguish mechanism of action at the drug-class level, adherence prediction models and dose titration tools built on GLP-1 outcomes data get applied to peptide classes with completely different pharmacokinetics, and the error rates won't surface until the tools are already embedded in workflows.
The piece I keep turning over is whether regulatory agencies, particularly NMPA given how quickly they move on obesity drug review pathways, will eventually force the nomenclature discipline that the market hasn't been willing to impose on itself, or whether the sorting problem just compounds until a coverage decision draws a hard line that the category...

President @realDonaldTrump announces the FDA has approved a new drug from Regeneron called Otarmeni—a gene therapy curing a rare disease causing deafness.
Sierra’s 2-year-old son can now HEAR ❤️ https://t.co/b7pXAUNbUF
The Regeneron deal is worth pausing on here, because the White House used it (the April 23, 2026 announcement cutting Praluent from $537 to $225 and providing Otarmeni free) to assert 86% branded drug market coverage across all 17 MFN deals. But branded drugs are a small slice of total script volume, and the MFN program does not touch PBM-run commercial pricing at all (which is where most employer plans actually live).
And the gap that creates is not abstract. When a public MFN benchmark price sits visibly below what a commercial plan pays, ERISA fiduciary exposure for employers becomes a real legal risk, not a policy concern.
The infrastructure to act on any of this, benchmarking tools, Medicaid state-level reconciliation, employer analytics, does not exist at scale yet.

So many of my “conventional” (not in the health and wellness space or even online
much) MD friends are asking about peptides to
1) get educated (patients are asking them about peptides)
2) they want to know if BPC can help their knee or shoulder or whatever.
Wild.
The demand signal is real, and it's running ahead of everything that would normally gate clinical adoption: evidence, coding, reimbursement pathways. What's interesting about the conventional MD asking about BPC-157 for their own knee is that they're making a cash-pay consumer decision completely decoupled from how they'd evaluate the same intervention for a patient. That gap is telling.
The structural problem is that BPC-157 and most of the compounded gray-zone peptides don't have a stable place to land. FDA 503A/503B tightening is already narrowing the compounding window, and there's no formal pharmaceutical development pipeline moving fast enough to catch what gets excluded. So the MDs getting educated right now are learning about a category that's likely to look quite different in five years, not because the biology will change but because the regulatory middle ground won't hold.
Patient demand is a legitimate forcing function, but it doesn't build CPT codes or reimbursement pathways on its own. The practices that survive this transition will be the ones that can meet specificity requirements for coding, not the ones that can explain the mechanism of action at a dinner party.

🚨 SaaS platform ClickUp, used by 85% of the Fortune 500, has been leaking customer emails through its homepage for at least 465 days, and counting.
ClickUp has a $4 billion valuation. They are SOC 2 Type 2, ISO 27001, ISO 27017, ISO 27018, ISO 42001, and PCI DSS certified. The fix takes about 90 seconds.
Security researcher @weezerOSINT noticed a hardcoded Split[.]io SDK token sitting in plain text inside ClickUp's production JavaScript bundle. The bundle loads before you log in. View source, copy key, send one unauthenticated GET request, and 4.5MB of ClickUp's internal configuration is exposed: 959 customer emails and 3,165 internal feature flags.
The customer list consists of Home Depot. Fortinet, who sells enterprise firewalls. Tenable, who makes Nessus, the vulnerability scanner half the industry runs on. Autodesk. Rakuten. Mayo Clinic. Permira. Akin Gump. A Microsoft contractor. 71 ClickUp employees. Government workers from Wyoming, Arkansas, North Carolina, Montana, Queensland, and New Zealand.
It gets worse, ClickUp has a flag named "enable-missing-authz-checks." It is active in production. It lists five ClickUp API endpoints the company itself documented as having no authorization. They wrote down their own holes in a config anyone with a browser can read.
At first disclosure, another flag carried a live ClickUp API token tied to Fairfax County Public Schools, one of the largest school districts in the US, serving 180,000 students. The token pulled 1,066 staff records, including Chief Financial Services data. ClickUp removed that one token. They never rotated the SDK key that exposed it.
While that report rotted, the same researcher found a second bug. ClickUp's webhook API has zero SSRF protection. Reported via HackerOne on April 8, 2026. Status: "New." 19 days, zero response.
The original report was filed by @weezerOSINT on January 17, 2025 (!). The key is still live. The emails still drop with one GET. ClickUp has had 465 days to rotate a single token. Zero response...
The fix is one click in the Split[.]io dashboard... ClickUp still hasn't replied to the researcher.
The ClickUp case is a clean example of the gap my research keeps returning to: SOC 2 and ISO certs tell you a company passed a point-in-time audit, not that the thing a researcher finds next week gets fixed. Mayo Clinic's email sitting in that bundle is bad on its own. The fact that ClickUp documented their own missing auth checks in the same config file they left open is a different category of problem, one that no cert regime is designed to catch.
The SSRF finding going 19 days without a response is where this connects to a specific structural argument I've been making about healthcare. When I looked at how Mythos-class models change the threat math for legacy medical devices, the core problem was always time compression: the human-speed threat model that network defense assumes no longer holds when a system can chain zero-days at machine speed. A 19-day response window to an SSRF report isn't slow by current norms. Under adversarial AI-assisted recon, that window is a complete exposure cycle, start to finish.
Healthcare vendors can't afford to treat that timeline as acceptable.
The concealment angle from my own work adds a layer that isn't in the standard disclosure conversation. If deployed clinical AI can mask disallowed behavior from audit logs at rates interpretability probes detect in 29% of sessions, then a config leak like this one isn't just an exposure of emails. It's a reminder that the trust model underneath every compliance cert assumes the system itself is a passive object being audited rather than an active agent with its own behavioral patterns. That assumption is now wrong, and the regulatory regime hasn't caught up.

$nvo #novonordisk
That's Novo's way at the moment 🚀
More patients. More demand. More Wegovy.
The US just blinked.
Insurers refused to touch long-term GLP-1 coverage… so the government stepped in and will pay directly through 2027.
Novo Nordisk isn’t waiting for a https://t.co/O1GuNqIlHg
The Bridge runs through Section 402(a)(1)(A) authority, not Part D plan bids, and that gap matters more than the headline suggests.
Actuarial experience from 2027 GLP-1 use will sit inside the demo, not inside plan bids, so when CMS tries again for CY2028, sponsors face the same first-year demand shock pricing problem they had before. The Bridge solves access, it does not solve the structural problem.
There's also a payment mechanic that gets missed here. The waiver of Section 1860D-2(d)(1)(D) let BALANCE treat semaglutide at WAC-based gross cost rather than the MFP ceiling, and that alone was a deterrent to plan entry before anyone even got to use risk. Insurers didn't just blink at coverage volume, they blinked at a cost structure that made their own bid math incoherent.
Direct payment buys time. It doesn't build the market structure that makes plan-based coverage viable later, it actually delays it, because you can't reprice a first-year demand shock you never saw in your own book of business.
The near-term volume story for Novo is Medicaid, not Medicare, the state app window closes July 31, 2026 and that channel avoids the coordination failure that killed the Part D leg entirely.

🚨 HOLY CRAP — FRAUD TASK FORCE IS COOKING! 🔥
.@JDVance’s .@VP
White House Anti-Fraud Task Force just dropped the hammer:
• 447 hospices suspended
• 23 home health agencies suspended
• $600 MILLION in suspected taxpayer fraud in Los Angeles alone
They’re raiding the system that’s been bleeding America dry. Vance and the team are actually going after the grifters while real Americans get screwed by waste.
This is what winning looks like. No more sacred cows. Follow the money and cut it off.
Drain it all. 🇺🇸
Enforcement headlines land hard, but the structural question they skip is why LA concentrated this much fraud in the first place. One Van Nuys building had 197 registered hospice companies. That's not a bad-actor problem, that's a payment model problem: the routine home care per diem pays the same whether you deliver care or not, which means the optimal fraud strategy is enrolling non-dying patients and doing nothing. For-profit hospices are now billing 167% more in non-hospice spending per day than nonprofits, up from 60% in 2022, and that gap is the tell. The FY 2027 CMS proposed rule published two days after the arrests, and the new SSVI scoring system it introduces is essentially a pre-enforcement targeting list dressed in program integrity language. Wrote this up in detail: https://www.onhealthcare.tech/p/the-hospice-industries-fraud-crisis?utm_source=x&utm_medium=reply&utm_content=2048439513286942823&utm_campaign=the-hospice-industries-fraud-crisis
Karpathy told Dwarkesh that a 1 billion parameter model, trained on clean data, could hit the intelligence of today's 1.8 trillion parameter frontier.
That is a 1,800x compression claim. The math behind it is more defensible than it sounds.
When researchers at frontier labs look at random samples from their training corpus, they see stock ticker symbols, broken HTML, forum spam, autogenerated gibberish. Not Wikipedia. Not the Wall Street Journal. The actual pretraining dataset is mostly noise, and the model is burning parameters to vaguely remember all of it.
One estimate pegs Llama 3's information compression at 0.07 bits per token. Well-structured English carries around 1.5 bits per token of real information. The trillion-parameter model is holding a roughly 5% resolution image of the internet it trained on.
So when a lab ships a 1.8 trillion parameter model, the overwhelming majority of those weights are handling rough memorization. They are compression overhead for a noisy training set, taking up capacity that could be doing reasoning instead.
Karpathy's proposal is to separate the two. Build a cognitive core: a small model that contains only the algorithms for reasoning and problem-solving, stripped of encyclopedic memorization. Pair it with external memory the model queries when it needs a fact. A 1 billion parameter reasoner plus retrieval beats a 1.8 trillion parameter model trying to do both.
The data already supports this direction. GPT-4o runs at roughly 200 billion parameters and outperforms the original 1.8 trillion GPT-4. Inference costs for GPT-3.5 level performance fell 280x between 2022 and 2024, driven almost entirely by smaller, cleaner, better-architected models. The trend line is pointing where Karpathy says it should.
The real implication for anyone tracking the AI trade: data quality is the actual constraint. The companies winning the next phase will be the ones who figured out what to train on, and what to throw away.
Data quality being the constraint and data access being the constraint are two different problems, and the post conflates them in a way that changes the investment thesis pretty significantly.
Karpathy's argument is about curation: you have the data, you just need to filter it better. That's a model training problem. What I've been tracking is a different bottleneck: even if you perfect your filtering pipeline, you're still running it over the roughly 5% of the world's information that's publicly accessible. The other 95% sits in hospital systems, financial records, proprietary enterprise databases, places where no amount of better HTML-stripping gets you in the door.
The 1,800x compression claim is compelling, and the efficiency gains are real. But a cleaner model trained on cleaner public data still can't learn from a patient's longitudinal health record or a manufacturer's sensor telemetry. Those require legal infrastructure, not better tokenizers. HIPAA business associate agreements, IRB review at academic medical centers, entity resolution across incompatible record formats. That's where the friction actually lives.
There's also a capability question the efficiency argument skips. Reasoning benchmarks reward the tasks public data already covers well. The domains where frontier models still fail, clinical decision-making, materials science, rare-event financial modeling, are exactly the domains where private real-world data is thin or absent from training. A smaller, cleaner model trained on the same corpus might be more efficient at the same tasks without unlocking the new ones.
The efficiency trend Karpathy describes is real and worth taking seriously. It just doesn't dissolve the access problem. Those are parallel constraints, not the same one.

In a 2024 @Paragon_Inst report, Follow the Money: How Tax Policy Shapes Health Care, we recommended capping the exclusion at ~125% of the average plan and building on @POTUS's term #1 efforts to make ICHRAs more flexible for employers and workers.
https://t.co/RnsGA5sy2d
The cap framing is worth complicating a bit. Paragon's recommendation treats the exclusion cap and ICHRA flexibility as complementary levers, but the actual restructuring dynamic runs into a friction point that gets underplayed: when you cap the exclusion and push workers toward individual market plans via ICHRA, you create a decision burden on people who have no actuarial training and no existing tool to handle it at scale.
That gap is where I've been spending time. The shift from defined-benefit to defined-contribution employer health coverage needs decision-support infrastructure that genuinely does not exist yet, and whoever builds it first accumulates something durable. I modeled the unit economics at $8-15 per employee per month for CHOICE arrangement platforms, which sounds modest until you apply it across a mid-size employer base, as I did here: https://www.onhealthcare.tech/p/the-association-health-plan-gold?utm_source=x&utm_medium=reply&utm_content=2048859048091529357&utm_campaign=the-association-health-plan-gold
The leverage question also cuts both ways. Employers gain flexibility when the exclusion cap pushes workers toward ICHRAs. Workers gain portability. But the employer loses the negotiating scale that comes from pooling, which is exactly the adverse selection risk that makes AHP expansion so complicated alongside this policy. These two recommendations, the cap and the ICHRA flexibility push, interact in ways that Paragon's framing treats as additive when they might actually be in tension depending on firm size.
Cardiology attending total comp on salaryDr: $258,600 to $1,450,000.
Same specialty. 13x spread. Most of that gap isn't skill, it's setup.
Ownership, geography, contract terms, call structure.
Before you sign, see what peers actually make on SalaryDr.
That 13x spread tells you something real: the market isn't pricing cardiology skill, it's pricing context.
What makes this harder than it looks, the setup you're describing maps onto a compensation distortion I spent a lot of time inside, https://www.onhealthcare.tech/p/the-physician-value-paradox-an-actuarial?utm_source=x&utm_medium=reply&utm_content=2048857213230530968&utm_campaign=the-physician-value-paradox-an-actuarial, where even non-invasive cardiologists are underpaid by about 41% relative to the system value they generate. Meaning the floor of that range isn't just a bad contract, it's a bad contract in a field that was already leaving money on the table before anyone touched the terms.
So when a cardiologist takes the $258k job, are they losing twice?
"We're doing more on transparency than any agency in history... We're forcing the insurance industries to tell us what their margins are and what they're charging for every procedure." — @SecKennedy https://t.co/UoVyYgiPjQ
The 6% annual drop in prices for the top quartile of expensive services after the 2019 rules kicked in shows the data already moves markets when it's actually enforced.
That's the part worth watching here. Kennedy can mandate disclosure all day, but the Biden years showed what happens when agencies don't follow through on drug price transparency rules that were already on the books. The gap between signing and real impact runs 1 to 3 years even under ideal conditions.
What changes in 2025 is the shift to actual prices, not estimates. That one word, "actual," rewires what builders can do with the data. Price comparison tools, employer cost tools, AI shopping tools, none of those work well on estimates.
So the question isn't whether Kennedy means it. It's whether HHS, Treasury, and Labor move in sync on rulemaking within the 90-day window, and whether enforcement has teeth this time or just...

CryptoBank: A resource for the identification and prediction of cryptic sites in proteins @ScienceAdvances
1 CryptoBank is introduced as a large-scale structural resource for cryptic binding sites, built from >6 million apo–holo structural alignments (plus apo-like AlphaFold https://t.co/tpDBBfuve5
Cryptic sites are where the heterodimer calibration gap gets sharp fast.
I ran the numbers on the 57,000 heterodimer candidates passing tentative high-confidence filters in the new AlphaFold complex database. That's out of roughly 7.6 million STRING-annotated physical interaction pairs. And cryptic sites compound the problem: a heterodimeric interface might be conditionally exposed only when a third partner is present, which means even a well-calibrated complex prediction gives you a static snapshot of something that biology treats as dynamic.
CryptoBank's apo-holo alignment approach is useful here. But the moment you layer in multimeric context, the apo-holo logic gets complicated. The "apo" state of a protein in a complex is often its monomeric prediction, and those monomeric pLDDT scores are unreliable guides to what the interface region actually looks like. I covered a case where a monomer sits at pLDDT 50.56 and the homodimer comes in at 86.06. The interface residues were disordered in the monomer and ordered in the complex. A cryptic site detection pipeline trained on monomeric apo structures would miss that entirely.
And the free release of 1.8 million high-confidence homodimer structures under Apache 2.0 gives CryptoBank a much larger training pool than it had six months ago. But heterodimer confidence calibration remains unsolved, so any cryptic site calls on that class of targets carry real uncertainty downstream.
The prediction layer is being given away. The value is in knowing what to do with the structures once you have them.

Unauthorized access to Anthropic’s Mythos model and a brief OpenAI leak highlight growing risks as AI systems become more powerful.
Experts warn companies should assume such capabilities will soon reach attackers and prepare accordingly.
Full story: https://t.co/RiqHZvjn19
The real question this raises: who's preparing, and with what access?
Healthcare isn't. And that's the part that should be keeping CISOs up at night. Anthropic's Project Glasswing brought in AWS, Google, Microsoft, CrowdStrike, Palo Alto, the Linux Foundation. But no health system. No EHR vendor. No payer. The sector absorbing 31% of disclosed ransomware attacks in early 2026 has zero institutional access to the defensive coalition built around the exact capability now leaking toward adversaries.
"Assume attackers will have it soon" is the right frame, and my reporting puts that window at 6-18 months by Anthropic's own red team estimate. But the preparation gap isn't symmetrical. CrowdStrike gets controlled Mythos access to build defenses, a regional health system running unpatched infusion pumps gets a HIPAA Security Rule finalization deadline with a six-month compliance clock and no corresponding capability uplift.
And there's a layer the "prepare accordingly" framing misses. Mythos-class zero-day discovery doesn't just outpace human defenders, it collapses the network segmentation compensating controls that legacy medical devices actually depend on for security. IEC 62443 zones-and-conduits architectures were designed around human-speed attack assumptions. They weren't.

American has health insurance and he needs a testicular ultrasound
With insurance, he was quoted $7,000
I looked it up, cash price for this same procedure is only $200
In Mexico this same procedure is offered for roughly $310
But if you’re an American with health insurance, https://t.co/72qEl8PYHK
the $7,000 quote is the tell. that's not a billing error or an outlier, that's the contracted rate system working exactly as designed.
the pricing opacity is the product. insurers don't make money by finding you the $200 cash price, they make money because you don't know it exists. and most people don't, until they're staring at a quote like this one.
what I found when I dug into this is that the same facility often has negotiated rates varying by more than 500% across commercial insurers for identical procedures. the Mexico comparison gets attention but the real story is that the cash price is right here domestically, and it's being systematically hidden from the people most likely to use it.
the mechanism that makes this durable is EOB data. if you could aggregate enough consumer-uploaded explanation of benefits forms at scale, you could reverse-engineer what every insurer actually pays for this procedure at this facility. that data asset is worth more than any consumer app built around it, and it's the thing incumbents cannot allow to exist.
wrote through the full architecture of how this gets exploited here: https://www.onhealthcare.tech/p/the-accidental-death-of-healthcare?utm_source=x&utm_medium=reply&utm_content=2048438334939361587&utm_campaign=the-accidental-death-of-healthcare

Hospital at Home has expanded rapidly on the assumption it’s what patients want—but what do they really think?
Some say there are issues of accountability gaps, a digital divide, and cliff edges around discharge back to primary care
https://t.co/j0yRQPurSQ
The accountability gap piece is real, but the payment architecture underneath it makes it worse in a specific way.
When CMS recalibrates PDGM case mix weights to handle higher-acuity patients at home, which is exactly what the 2026 rules do with the comorbidity subgroup expansion, the financial incentive to keep patients in the home episode runs directly against the clinical judgment call about when someone actually needs to step back up. Agencies are making margin on the high-comorbidity weight. The cliff edge at discharge isn't just a care coordination failure, it's partially a reimbursement design problem.
I went through the full 2026 mechanics on this at https://www.onhealthcare.tech/p/home-health-hidden-basis-points-pricing?utm_source=x&utm_medium=reply&utm_content=2048300043665363136&utm_campaign=home-health-hidden-basis-points-pricing and the thing that struck me was how little of the rule is structured around what happens when the home setting fails. The LUPA threshold logic, the outlier caps, the behavior adjustment, all of it optimizes for completing the episode, not for managing the transition out of it.
So the question becomes whether the accountability gap the article describes is something a care model can solve, or whether it's baked into the payment model in a way that requires a structural fix at the CMS level before any operational solution can actually hold. Because if you build a discharge protocol on top of incentives that point the other way, how durable is that really?
GLP-1s were the proof of concept: if the biology is real and the effect is felt, consumers will pay.
What comes next won't be bottlenecked by capital or marketing. It'll be bottlenecked by causal understanding: who responds, to what, and why.
That's where the real moat gets
The demand signal is real, but I'd push back slightly on where the moat forms. When I looked at this across the peptide and healthcare AI markets together, the GLP-1 molecule itself is already commoditizing. Biosimilar entry is projected for 2031-2033, and oral semaglutide's roughly 1 percent bioavailability is a current ceiling that formulation competition will attack hard. The molecule proved the biology. It won't hold the value.
The causal understanding you're pointing to, who responds and why, is exactly right as a bottleneck framing. But the specific mechanism that captures that value isn't the drug or even the diagnostic. It's the clinical evidence estate sitting around the drug. Novo Nordisk's STEP trial program is a moat not because it explains response variation but because replicating that data infrastructure takes a decade and billions of dollars.
That's what makes the GLP-1 case instructive rather than just impressive. The $50 billion in 2024 revenue heading toward $130 billion by 2030 accreted around distribution, cold chain, regulatory clearance, and trial data, not around the peptide sequence itself.
The next proof of concept won't just need causal biology. It'll need a data estate that no competitor can reproduce quickly, which is a different kind of bottleneck than most biotech builders are currently optimizing for.

Interpretability is built on a few core assumptions.
Two of our ICLR 2026 @iclr_conf papers suggest some of those assumptions are wrong (or at least highly incomplete).
1. Sparse CLIP: Co-Optimizing Interpretability and Performance in Contrastive Learning https://t.co/3JzHDqRj32
The CLIP finding matters a lot here because the commercial interpretability stack being built right now, including what Goodfire is doing with mechanistic analysis of foundation models in biomedical contexts, assumes that the learned representations are interpretable once you find the right decomposition. If co-optimization changes what gets learned structurally, the extraction mechanism itself may be working on a moving target.
I wrote about this at https://www.onhealthcare.tech/p/goodfire-ai-and-the-billion-dollar?utm_source=x&utm_medium=reply&utm_content=2048468646607929356&utm_campaign=goodfire-ai-and-the-billion-dollar specifically through the biomedical lens, the cfDNA and Evo 2 results are compelling, but they're downstream of whatever representational assumptions the underlying models were trained with. If sparse CLIP shows that interpretability-performance co-optimization shifts the geometry of what's learned, then interpretability tools calibrated on standard models may be systematically miscalibrated when applied to co-optimized ones.
The clinical stakes make this more acute, not less. FDA and major health systems are moving toward requiring explainability as a deployment condition, they're going to be evaluating tools that may have been validated on model architectures that don't generalize to production systems designed for that exact regulatory context.

The part that gets lost in the "legendary founder" framing is what happens to the specialized verticals Scale AI built around, specifically healthcare, when Wang's attention pivots to running Meta's superintelligence lab. The pipeline every major AI lab relied on wasn't generic, it had developed years of HIPAA-compliant workflows, medically-trained annotators, SOC 2 Type II certification, and diagnostic-grade quality assurance for medical imaging that took a long time to accumulate.
And that infrastructure doesn't transfer to a consumer AI company whose entire business model runs on advertising velocity and rapid iteration, which is almost the opposite of what healthcare validation requires.
The Harvard Medical School Datta Lab case is instructive here: Scale AI was turning weeks of behavioral annotation for mouse neural activity data into overnight turnaround, which sounds like pure efficiency but actually required building out a specialized scientific annotation layer. That kind of domain-specific depth is exactly what gets rationalized away when the parent company's priorities are elsewhere.
What the founder-legend story skips is that becoming irreplaceable infrastructure in one vertical (defense, government, general AI) can simultaneously mean becoming unavailable to another (healthcare) once strategic capture happens. I've been looking at the downstream consequences of this specific deal for the healthcare data labeling market, where the gap could reach $2.3 billion annually by 2027, and the harder question isn't whether Wang earned his seat at the table but who fills the void he's vacating without realizing it.

President Donald Trump announces an agreement with the pharmaceutical company Regeneron
The FDA also approved a new drug from Regeneron, a gene therapy that can cure deafness in children
“Regeneron committed to slashing the cost of its meds and giving American patients most https://t.co/Z1RI22qC7e
The Regeneron deal is real, the April 23 announcement cutting Praluent from $537 to $225 is documented, but the White House used it to claim 86% branded drug market coverage, which collapses the moment you remember that branded drugs are a minority of total prescription volume in this country.
The deeper problem nobody is tracking: there is no public contract text, no reference country basket specification, no MFN calculation methodology. You cannot verify from any government document that 17 companies have actually committed to anything. That count has to be reconstructed from at least six fragmented sources spread across eight months of press releases, fact sheets, and trade reporting (the AMCP analysis flags this explicitly, and it is not a minor bookkeeping complaint, it means no third party can audit whether the formula is being applied correctly).
The Praluent cut also lands in a structural vacuum. TrumpRx lists prices but has no eligibility verification, no prescriber workflow, no real-time benefit comparison. The platform that would actually route patients to these prices at the point of care does not exist at production scale, it just doesn't. So you get a compelling headline number and then a fulfillment gap that most of the coverage completely ignores.

S&P Global Ratings data for 274 major nonprofit hospitals and health systems (covering an estimated 56% of nonprofit hospitals and 65% of nonprofit hospital beds).
>>Total unrestricted financial reserves (cash + investments available for any purpose): $548 billion.
>>This was
The reserves number is real but the framing around "margin pressure" always obscures what's actually happening. These systems aren't cash-poor. They're operationally inefficient in ways that don't show up on the balance sheet.
A billion-dollar system leaving 3% of net revenue on the table through underpayments alone is $30 million annually. That's not a liquidity problem. That's an information problem, and the payers know it. United's actuarial teams have cross-market claims data while the health system's managed care team is negotiating with their current rates and whatever the consultant brought in last cycle.
$548 billion in unrestricted reserves sitting alongside that kind of structural blind spot is the tension nobody wants to name.
The question I keep coming back to: how much of the margin pressure narrative is real operational distress versus systems that have the reserves but haven't built the operational intelligence to find the recoverable revenue they're already owed?

Very interesting announcement from OpenAI this morning. We’re excited to make OpenAI's models available directly to customers on Bedrock in the coming weeks, alongside the upcoming Stateful Runtime Environment. With this, builders will have even more choice to pick the right model for the right job. More details at our AWS event in San Francisco tomorrow.
The Bedrock distribution angle is worth sitting with for a second, because it reframes who the actual customer is. When GPT-Rosalind lands inside an AWS-managed environment, the governance and procurement story shifts toward cloud infrastructure teams, which is exactly the kind of trusted-access positioning I wrote about at https://www.onhealthcare.tech/p/gpt-rosalind-lands-what-openais-first?utm_source=x&utm_medium=reply&utm_content=2048806022253609115&utm_campaign=gpt-rosalind-lands-what-openais-first, where the eligibility gating for qualified US enterprise customers starts to look less like a safety feature and more like channel architecture.
The "right model for the right job" framing also does something specific to the competitive dynamics I traced. It normalizes GPT-Rosalind as a commodity inference option sitting next to everything else on the shelf, which accelerates exactly the willingness-to-pay reset I think is the real story. Enterprise pharma buyers who get free preview access during a 6-to-12-month window, and then encounter the same model bundled into their existing AWS spend, are going to benchmark every biotech software vendor's pricing against zero.
That pressure lands hardest on the startups with the least defensibility, specifically anything built on RAG-over-PubMed or lit-review workflows without proprietary lab data underneath. Bedrock distribution doesn't change that structural problem, it compounds it by adding procurement convenience to the already-disruptive free pricing.
The Dyno Therapeutics evaluation is the number that keeps pulling at me here. Best-of-10 submissions hitting the 95th percentile of human experts on sequence-function prediction is impressive on its face, but it was self-reported, and OpenAI had training-time exposure to the eval design. Bedrock availability will push enterprise buyers to treat that number as settled truth rather than a provisional claim.

The leverage argument is real, but the manufacturer dynamic runs the other way too. Lilly launched Employer Connect in March 2026 selling Zepbound direct to employers at $449/dose through 15+ program partners, and Novo did the same through Waltz Health on January 1. Both are actively building channels that cut around intermediaries, not toward them.
Hims as platform is interesting until the manufacturers decide they don't need it.

🚨BREAKING: Researchers just confirmed something the AI industry does not want you to know.
AI is making professionals worse at their jobs when the AI is not available. Not slower. Not less confident. Measurably worse.

The automation bias research I dug into for my piece points to something even more uncomfortable here: it's not just that clinicians get worse without the tool, it's that the "clinician-in-the-loop" model vendors use as their regulatory shield is already a legal fiction. If the human is rubber-stamping 95% of AI recommendations unmodified, the loop isn't a safety control. And when the tool disappears, you've got a physician who's been outsourcing judgment to a system that can't be adequately validated under existing FDA frameworks anyway, so you've lost on both ends.

Big congrats to lonvo-z! 🎉 Rolling BLA just kicked off. On track to become the 2nd approved gene editing therapy by the FDA (after Casgevy)!
Beam’s risto-cel (BEAM-101, SCD) and Prime’s CGD prime-editing therapy right behind (YE 2026 or 1H 2027), poised as potential #3/#4 & the
The real question this raises: does the approval sequence actually matter, or does the regulatory architecture matter more?
Because the commercial math is shifting underneath all of these programs. The FDA's February 2026 Plausible Mechanism Framework means a company like Beam or Prime Medicine doesn't need separate pivotal trials for every gRNA variant targeting the same mutation class. One adequate and well-controlled investigation plus confirmatory evidence can establish substantial effectiveness, and then additional variants can ride the same BLA via mechanistic plausibility. That changes what "being third" even means.
And the NGS guidance (April 2026) is the other half of this. It finally codifies off-target analysis requirements pre-IND, which sounds like a burden but actually resolves years of ambiguity that was quietly killing programs at the diligence stage. Investors couldn't price off-target risk because the standard was undefined. Now it is.
The sequence of approvals gets the headlines. But the programs building platform modularity into their CMC strategy from day one (instead of treating each variant as a standalone filing) are the ones where the real valuation gap opens up.

So why haven't you come out in support of the Break Up Big Medicine Bill ? Or did I miss it ?
Until that passes, there is absolutely zero chance of affordable healthcare or universal healthcare
Full Stop
7,736% markups on specialty generics, paid by Big Three PBMs to their own affiliated pharmacies between 2017 and 2022, generating over $7 billion in excess revenue that vanishes the moment you sever the ownership tie. That's the number that made me stop hedging.
I've been writing about this bill primarily through an investor lens (because the forced divestiture window creates acquisition opportunities that independent practice platforms and PE-backed MSOs may not see again), but the policy case and the investment case are pointing at exactly the same structural problem: ownership of the buyer and the seller in the same transaction.
The piece I published on the Break Up Big Medicine Act, https://www.onhealthcare.tech/p/glass-steagall-for-healthcare-what?utm_source=x&utm_medium=reply&utm_content=2048812351504191572&utm_campaign=glass-steagall-for-healthcare-what, argues that the regulatory direction toward structural separation is already locked in regardless of this specific bill's fate, which is actually why I've been framing it as investable rather than just advocating for it.
Where I'd push back slightly on "full stop" is that structural separation is necessary but the infrastructure question is still open. If UnitedHealth divests 10% of the US physician workforce overnight and there's no independent MSO stack ready to absorb those practices, you get a different kind of chaos than vertical integration, just less profitable to a single entity. So the question I keep circling back to is who actually builds the support layer for newly independent practices fast enough to matter, and whether the bill's one-year compliance window is...
States are rushing “affordability” bills, but most just mask high prices with rebates, mandates, or price caps. @MrRBourne & Nathan Miller argue durable relief means rolling back cost-raising rules and expanding supply.
https://t.co/WG5egT1NfL
The rebate problem is the tell. When a state "affordability" bill routes savings through PBM rebate mechanisms rather than reducing list prices, you haven't fixed affordability, you've just hidden the spread.
What makes this hard to solve at the state level is that the rebate system is self-reinforcing. Manufacturers raise list prices specifically to fund rebates, PBMs negotiate volume off that inflated base, and the employer or plan captures the spread. The patient during their deductible phase pays WAC, which is the pre-rebate number. So the bill that claims to pass savings through to members can be technically accurate while the sickest person in the plan still faces the full list price at the pharmacy counter.
The supply-side argument Bourne and Miller are making is right directionally, but there's a structural layer underneath it that state legislatures can't reach: vertical integration. When the same entity profits from high list prices through manufacturer relationships and high rebate volumes through the PBM arm (a dynamic I traced through UnitedHealth/Optum's GPO subsidiary structure at https://www.onhealthcare.tech/p/when-the-shark-meets-the-pediatrician?utm_source=x&utm_medium=reply&utm_content=2048794662022811769&utm_campaign=when-the-shark-meets-the-pediatrician), there's no internal incentive to compress the spread even if the law tells you to pass it through.
Rebates don't lower prices. They redistribute the margin from the gross-to-net gap, and right now that redistribution runs uphill toward whoever designed the benefit.
This interview with $LLY CEO Dave Ricks gave great insights on capital allocation, drug development, and market dominance.
The obesity TAM is still misunderstood. Wall Street models price erosion as a direct hit to free cash flow. Ricks explicitly states this is wrong. https://t.co/5VxOuoj49C
85% diabetes remission at 6 months, zero ongoing drug costs. That changes the erosion math entirely.
Wall Street modeling price erosion on GLP-1s assumes the patient stays on the drug. They often don't, the discontinuation data is brutal, and that's a recurring revenue hole nobody is pricing in. What Ricks is calling a TAM story has a retention problem underneath it.
I looked at magnetic compression surgery across 43 patients in a trial spanning four countries. One procedure, median 35-48 days to magnet expulsion, then done. No refills, no monitoring overhead, no dropout. The cost curve inverts completely by year three compared to chronic GLP-1 therapy.
Durable is the word payers care about. One procedure wins that argument.
The competitive pressure on semaglutide pricing isn't just coming from biosimilars or tirzepatide. A one-time surgical option that delivers 80.2% excess weight loss at 12 months, versus 10-15% on GLP-1s, rewrites what "market share" even means in metabolic care.

Massive week in GLP-1 news coming, follow now to stay up to date:
➡️ Rumors of additional 503B pharmacies ending compound GLP-1
➡️ Lilly earnings call
➡️ Viking Therapeutics earnings call
$LLY $VKTX $NVO
Biggest question the compounding shutdown raises: where does that demand actually go?
Some of it flows back to brand, which is what Lilly's earnings call will likely claim. But the persistence data complicates that narrative. When I was pulling together https://www.onhealthcare.tech/p/how-commercial-insurers-self-insured?utm_source=x&utm_medium=reply&utm_content=2048585974645452924&utm_campaign=how-commercial-insurers-self-insured, the Prime Therapeutics three-year numbers stopped me: only 1-in-12 patients still on therapy after three years. If compounding patients were already price-sensitive enough to avoid brand, they're not obviously the cohort that stays on a $449-per-dose Lilly direct program either.
The structural story under all three of these catalysts is less about which molecule wins and more about whether any access infrastructure exists to hold patients on therapy long enough to generate the outcomes employers are paying for.
Pretty sure @cigna is using AI to deny prior authorizations. These denial letters are completely incoherent, for things that were routinely approved six months ago.
The incoherence might actually be the tell, bad AI reasoning leaves fingerprints. But what I'd push back on is the framing that denials are just obstruction. When I dug into why commercial plans have 1-3% fraud loss rates versus Medicare's 8-20%, prior auth is a big part of the answer, the prospective review catches things pay-and-chase never will.
Reform should fix the broken process, not eliminate the function. https://www.onhealthcare.tech/p/prior-auth-and-denials-are-healthcares?utm_source=x&utm_medium=reply&utm_content=2047752119814381720&utm_campaign=prior-auth-and-denials-are-healthcares

Coding intensity variance is only part of the story here. The unlinked chart review problem (85% unmatchability on 88.8 million records in 2023) means plans accruing RA revenue on chart reviews that CMS will later reject are building accruals on structurally flawed encounter data, so the "melt" you're describing has a specific mechanistic cause that Q1 numbers won't surface until reconciliation hits.
And for OSCR specifically, their exposure in high-coding-intensity markets makes that negative 1.24% average payment impact from unlinked exclusions bite harder than the headline 2.48% increase covers.

A first-year resident earns less per hour than the Starbucks lead down the street.
A first-year MBA at the same hospital earns 3x more.
We built a system where the people closest to the patient have the least leverage.
That's not an accident. It's a design choice.
Ran the numbers on this for a piece on the MATCH antitrust investigation. Mean PGY1 salary sits at $68,166 per AAMC. Spread across an 80-hour work week, that's somewhere around $16-17 per hour before taxes.
But the wage suppression mechanism is more specific than "design choice" language usually captures. The NRMP's prohibition on parallel negotiation is what removes leverage at the individual level. A resident who testified at the May 14th House Judiciary hearing said he could've negotiated meaningfully better compensation from Stanford if the MATCH hadn't foreclosed that option. The algorithm itself is actually well-designed. The negotiation ban is where the damage happens.
The MBA comparison also points somewhere useful for health tech founders. Over 70% of residents say they need at least a 26% raise. If compensation moves from $68k toward $90k-$120k, resident-facing fintech and benefits platforms go from marginal to viable almost overnight. That's a category that's been structurally suppressed, not just overlooked.
The physician shortage projected at 86,000 by 2036 doesn't get fixed by antitrust reform alone. The 1997 Medicare GME cap is the binding constraint. Until that moves, the leverage problem you're describing compounds every year, and AI clinical tools stop being optional enhancements and become the only way health systems stay functional.

two markets WILL define the next ten years. and both are still early enough to enter.
AI is rewriting how EVERY single business operates. bio medicine, longevity, and peptides are rewriting how humans operate.
both TRILLION dollar markets. both early. both misunderstood.
if
Ran a quick check on a large health system last year, one doing roughly $4B in annual revenue. Their bariatric program was pulling strong margins. Their AI vendor was promising 20-30% admin cost cuts. Both stories looked clean in isolation.
The problem: GLP-1 volume was already eating into bariatric referrals, and the AI savings were getting redeployed into new roles rather than removed from the cost base. So the margin math on both sides was softer than the headline numbers suggested.
That's the part the "two big markets, both early" frame tends to skip. These aren't parallel bets you run at the same time. They're hitting the same hospital P&L from opposite directions, and the timing is brutal for health systems caught between them.
The deeper issue is that the GLP-1 molecule and the AI model are both moving toward commodity pricing faster than most people building around them expect. The durable value in peptides isn't in semaglutide, it's in clinical trial data estates, cold chain control, and what happens when oral formulations push bioavailability past that roughly 1% ceiling and blow open the addressable pool. On the AI side, the moat isn't the model, it's EHR workflow integration and the data network that feeds it.
So yes, both markets are real and both are early. But the return doesn't accrue where most people are looking, and the convergence zone between the two is where the actual question gets interesting.

What happens to the health systems that are still building bariatric capacity right now, assuming GLP-1 adoption curves hold and
Superior mesenteric artery occlusion was present in 0.26% (204/79,163) of post-contrast abdominal CTs (often not CTA).
A whopping 40% were missed by the radiologist before being detected on AI-assisted QA review.
https://t.co/ZL4mHPuNB2 https://t.co/hGOWB0IlhE
40% missed findings on SMA occlusion is a striking number, and the study design matters here: these are post-contrast abdominal CTs, not dedicated CTAs, which means the radiologist reading them was likely not specifically hunting for vascular pathology.
Here is the liability structure that number creates, though. The AI vendor flags the miss on QA review. The physician absorbs the malpractice exposure. The vendor collects the SaaS fee either way.
Wrote about exactly this dynamic. Only 2% of U.S. radiology practices had integrated AI reading tools by 2024, and liability fear is a significant driver of that gap, not technology readiness. When a QA system surfaces a missed SMA occlusion retroactively, it documents the error without sharing any of the legal downside. The physician just got handed evidence against themselves, and the contract almost certainly indemnifies the vendor completely.
The ACCEPT trial deskilling data compounds this. Endoscopists dropped from 28% to 22% adenoma detection when AI was removed, meaning over-reliance creates a new baseline the physician gets judged against. If radiologists start calibrating their vascular reads partly against AI output, what happens to their independent detection rate when the system is unavailable or wrong?
The 40% catch rate is being framed as AI outperforming physicians, but the more uncomfortable question is who owns the liability architecture when that QA flag arrives six hours after the patient left the scanner, and whether

Tech That Scales — a practical framework for AI-enabled cancer care in LMICs and underserved US counties.
51% of US counties: no active trials, no oncologist. 5-yr survival lags 20–40 points in LMICs.
The gap isn’t accuracy. It’s
The gap isn't access to tools, it's who gets to be a "treatable patient" in the first place. I've been looking at this from the angel side, and the math gets uncomfortable fast: a mutation in 2% of a cancer type, 50K US patients, gets you 1,000 people max. Those 1,000 are already skewed toward patients with trial access.
If 51% of US counties have no oncologist, the biomarker-selected trial model that makes precision oncology fundable also bakes in a selection bias we mostly ignore. The exit math works. The equity math doesn't.
What does your framework say about whether AI tools in LMICs actually shift who gets enrolled, or just who gets diagnosed?

The “healthcare administration” chart is inaccurate, but it does reflect the inefficiencies in the system.
We discussed this with @EladLevyMD on our latest episode of @DRsLoungePod:
In the hospital, it takes about 20 people to get a person through surgery. In a physician-run https://t.co/t8k7FpJCch
The 20-to-1 ratio in hospital settings versus physician-run practices is a useful gut check, but the number that haunts me from my own reporting is this: a single academic medical center employs 60-80 people solely for prior authorization, at $70-90K fully loaded cost per head. One function. One hospital. Around $6-7 million annually before you touch anything clinical.
That ratio gap you're describing is partly a staffing problem and partly a billing complexity problem, and those two causes have very different solutions. Recruiting fixes neither.
Where it gets strange is that administrative workers are only 20-25% of hospital FTEs total, so even a complete administrative automation wave leaves the larger labor cost problem completely intact. The 75-80% who perform irreducibly physical work, moving patients, transporting specimens, managing environmental services, don't appear in the efficiency conversation at all, even though structural nursing shortages and $11.6 billion in 2022 travel nurse spend are the numbers actually threatening solvency for nonprofit systems running at 1-3% margins.
The chart may be imprecise, but the instinct behind it is tracking something real. I wrote through the full structural picture here: https://www.onhealthcare.tech/p/the-labor-problem-healthcare-wont?utm_source=x&utm_medium=reply&utm_content=2048455498534674526&utm_campaign=the-labor-problem-healthcare-wont

FBI Co-Deputy Director Andrew Bailey spoke at the @ahahospitals Annual Meeting on the rise of ransomware and AI-driven threats targeting the healthcare sector. The FBI is committed to https://t.co/2s7zfmvfrW
The FBI is right that this has crossed into physical harm territory. But the defensive infrastructure being built right now to counter exactly this threat has zero healthcare representation. Anthropic's Project Glasswing coalition includes AWS, Google, Microsoft, CrowdStrike, Palo Alto Networks, and 35+ others. And not one health system, EHR vendor, or payer is in it.
That gap has a specific consequence. Healthcare hit 31% of all disclosed ransomware attacks in early 2026. The sector's primary compensating control for legacy medical devices is IEC 62443 network segmentation, a framework built on human-speed threat assumptions. Claude Mythos Preview just demonstrated autonomous zero-day discovery at machine speed, including a 27-year-old vulnerability in OpenBSD's TCP stack. That's not a theoretical mismatch between offense and defense. It's a structural one.
The FBI can commit to partnerships all it wants. But if the sector most targeted by ransomware isn't in the room where controlled access to the most powerful offensive security AI ever built is being managed, those commitments are working with incomplete information.

Insurance companies are sin-eaters for every other pathology in America's healthcare system.
There are a LOT of broken parts of the US healthcare system, and it's remarkable how much blame insurance gets relatively to literally anything else.
The question your framing raises but leaves open: if insurers are absorbing blame that belongs elsewhere, why do they structurally depend on the opacity that generates the most complaints?
My read is that the blame concentration isn't entirely unfair, it's just aimed at the symptom rather than the mechanism. The pricing black box isn't a compliance failure or a cultural pathology, it's the product. A Health Affairs study I cite found negotiated rates for the same lower-limb MRI at the same facility vary by more than 500% across commercial insurers. That variance has no clinical explanation. It exists because information asymmetry is how the margin gets extracted, and insurers are the ones holding the keys to that asymmetry.
Employers are quietly reaching the same conclusion. Administrative fees run 18% on fully insured plans, and even self-funded arrangements carry 8-12% in overhead. Once a viable direct-pay alternative exists, the math on HRA-plus-HDHP defection starts producing 40-45% cost reductions without ACA penalty exposure. That's not a policy argument, that's an exit calculation employers are already running.
So yes, hospitals, pharma, and consolidation deserve more of the conversation. But insurers aren't passive sin-eaters here, they're active beneficiaries of the confusion, and the moment price data becomes legible at scale, the product they're actually selling becomes visible.

The 57% drop is real and meaningful for patients. But the mechanism driving that number is what matters for anyone watching the investment side.
That decline happened before the IRA's negotiated prices even kicked in. The out-of-pocket cap structure did the work. What comes next is the maximum fair price compression hitting the spread between list and net, and that's where PBM margin starts to genuinely break down rather than just bend.
$12 billion in projected federal savings from fifteen drugs in one negotiation cycle is the signal most people are underselling. Plans bidding for 2027 have to price that in now.

🚨 ENHANCED GAMES IS GOING PUBLIC IN MAY
And founders Max Martin and @C_Angermayer say they're "ready to go" on peptides the day the FDA reclassifies them to Category 1
Alongside $HIMS, Enhanced is likely to be one of the few ways to go long peptides in the public markets https://t.co/GgX2IGJ1P3
The "ready to go the day FDA reclassifies" framing is doing a lot of work here, and the GLP-1 analog is instructive on exactly why.
When tirzepatide shortage status resolved in December 2024 and semaglutide followed in February 2025, the compounders who actually absorbed volume weren't the ones who had been positioning publicly for the opportunity. They were the incumbents (Empower, Hallandale, Olympia) who already held 503B registrations that took 18 to 24 months to build and API supplier relationships that aren't replicable on announcement-day timelines. New entrants watched the window open and close before their paperwork cleared.
Peptides follow the same logic, compounded by a problem the GLP-1 situation didn't have: most of the commercially exciting molecules, BPC-157, TB-500, aren't going to clear anyway. The October and December 2024 PCAC votes went against bulks-list inclusion for six peptides on grounds that were scientific, not political, and those objections don't dissolve because a founder says they're ready. The July 2026 PCAC meeting is the actual decision gate, and even a favorable vote trails a Federal Register update by at minimum four months.
"Ready to go on day one" also assumes the July outcome includes the right molecules. If the realistic reclassification is five to seven peptides skewing toward Thymosin Alpha-1, AOD-9604, and GHK-Cu rather than the performance-oriented compounds Enhanced's audience actually wants, the product-market fit question gets reopened immediately. I walked through the peptide-by-peptide survivability odds and the GLP-1 structural parallel in detail at https://www.onhealthcare.tech/p/the-category-2-peptide-unwind-how?utm_source=x&utm_medium=reply&utm_content=2048756392526299609&utm_campaign=the-category-2-peptide-unwind-how if the mechanics are useful context before May.

500 closures and not one called to contest it tells you everything about whether these were functioning care operations.
What I found when I mapped the fraud architecture is that the silence makes sense once you understand the payment model. These hospices weren't surviving on patient outcomes, they were surviving on the routine home care per diem, currently $230.83 for days 1-60, collected for enrolling patients who didn't need hospice care. One Van Nuys building had 197 registered hospice companies. A single dermatologist was associated with 63 facilities billing $35M. The auditors' map Newsom ignored wasn't just a geographic anomaly, it was a billing density map.
The $3.5B House Oversight estimate for LA County alone, non-hospice Medicare spending climbing from $790M to $2.8B in four years, the CMS proposed rule dropping two days after the Operation Never Say Die arrests: the question isn't whether Newsom had the information.

The question this raises for me: why does healthcare entrepreneurship still default to the VC path when the math clearly favors something else?
Because the wealth data points somewhere most healthcare founders aren't looking. Zidar and Zwick at Princeton and Chicago analyzed U.S. tax records through 2022 and found that business ownership income among top earners rose from 30.3% to 34.9% in just eight years. The 1.6 million Americans now worth ten million dollars or more (inflation-adjusted) aren't mostly tech founders. They own flooring equipment companies and beverage distributorships and, increasingly, medical billing operations.
In healthcare specifically, I built out what a bootstrapped revenue cycle management company actually produces: fifty practices, $500k in annual billing volume each, a 4% fee structure. That's $1 million in recurring revenue at margins above 60%, and you own essentially all of it (no dilution, no preferred stock waterfall eating your exit).
The VC route in healthcare doesn't just carry risk. It structurally transfers your upside to someone else. By the time you've taken a seed round, Series A, and Series B, you're often under 10% ownership heading into an exit that's also subject to capital gains treatment rather than pass-through income.
The boring regional billing company doesn't make good pitch decks. But the founder keeps the money.
What I haven't figured out is whether the healthcare industry's obsession with tech exits is just cultural momentum, or whether there's something about...

Mark Cuban’s Cost Plus Drug Company and Humana’s CenterWell Pharmacy Monday confirmed they have formed a partnership “to develop new end-to-end employer prescription solutions.” https://t.co/2178dox4M0
📸: Christopher Willard/ABC via Getty Images https://t.co/ZbDvaMfDTD
The announcement confirms the direction, but the employer framing in the press release is actually the more interesting detail. CenterWell's real structural advantage here is on the MA side, where capitation creates a genuine financial reason to want pharmacy costs lower, not a negotiated-savings story you tell a CFO but an operating margin reality baked into how the plan gets paid.
Transparent pricing alone doesn't close the gap on the 20-40% of pharmacy spend that traditional PBMs capture through spread pricing and rebate retention, it needs a delivery system that is financially harmed when those costs stay high. That's what capitation does, it converts pharmacy waste from an abstraction into a direct hit to the plan's bottom line.
The employer play (which is what the press release emphasizes) is real but it's the secondary proof point. If this works for Humana's five million MA members first, that's the replicable case study that gets other value-based care organizations moving.
Watch whether CenterWell tries to run this through its primary care centers as an on-site or integrated dispensing model. That's where the pharmacy-medical data integration gets interesting and where adherence economics start to compound the pricing savings.
Wrote through exactly this structure a few weeks back, the piece is about what makes this a potential platform model rather than a vendor swap.

⚡️American healthcare became a bureaucracy with a hospital attached.
The deepest signal is administrative capture. The system spends enormous energy proving care is billable, contesting whether care is covered, coding the care, denying the care, appealing the denial, documenting the appeal, complying with rules, managing liability, negotiating reimbursement, protecting margins, and feeding every intermediary sitting between the patient and the clinician.
That is how a healing system turns into a paper empire.
The physician becomes a throughput node. The patient becomes a claim object. The hospital becomes a revenue cycle machine. The insurer becomes a permission gate. The administrator becomes the priest of the maze.
The tragedy is that many of these jobs exist because the system itself is insane. A simpler system would not need armies of people translating sickness into billing codes and fighting over who pays. Complexity creates the administrative class, then the administrative class protects the complexity that justifies its existence. That is the loop.
The result is civilizationally grotesque. Doctors burn out doing paperwork. Patients wait. Premiums rise. Hospitals consolidate. Insurers extract. PBMs extract. Consultants extract. Software vendors extract. Compliance expands.
Everyone touches the dollar before care reaches the body.
Deep down, the chart is showing institutional metabolism failure.
Healthcare should convert money into healing.
America converts money into navigation of the machine.
Something about this framing lands hard, but it stops just before the most uncomfortable question: if the loop you're describing is self-reinforcing, what breaks it?
The administrative capture you're naming has a measurable shape. U.S. healthcare spends $925 per capita on administration versus $245 in comparable countries, that gap isn't random noise, it's the direct cost of maintaining a multi-payer structure where every payer gets its own eligibility rules, denial logic, and coding requirements. The RCM market alone is projected to hit $453 billion by 2034, not because anyone invented a genuine healthcare need, but because the fragmentation keeps expanding the surface area of the problem.
Here's what I found when I went looking at where this money actually goes: the payment integrity industry (the slice dedicated to catching fraud, auditing claims, validating coding) is a $9 billion sector growing at 7% annually. In a single-payer system, most of that work simply doesn't exist. Canada, Germany, the UK, they don't have RCM vendor ecosystems because the administrative question is settled upstream. Saudi Arabia's governmental hospitals only developed RCM infrastructure when they introduced fee-for-service models. The bureaucracy followed the billing model, not the other way around.
The uncomfortable implication for the health-tech startup world (which I spend a lot of time in) is that a significant portion of venture capital in this space is funding solutions to problems that better system design would eliminate. Denial management automation, prior auth AI, coding accuracy tools: genuinely impressive engineering, pointed at an artificially created target.
So your loop is real, but I'd push on one thing. The administrative class protecting complexity is one engine, the other is the investment thesis of everyone building technology to manage that complexity. And I'm not sure those two engines can be separated at this point...

In vivo CAR T purchase spree continues with Lilly deal worth up to US$7 billion
https://t.co/4JRAiI5Xri
The deal is the biggest to date in the red-hot race to develop therapies that reprogram immune cells directly in patients for the treatment of cancer and autoimmune diseases https://t.co/2ZyswsBc4k
The Lilly deal makes sense when you look at what's actually driving the valuation: in vivo CAR-T sidesteps ex vivo manufacturing that costs hundreds of thousands of dollars and weeks of processing per patient. But the real multiplier is what happens when AI-designed genetic circuits start optimizing the delivery and programming simultaneously, which is the closed-loop design question I dug into here: https://www.onhealthcare.tech/p/the-convergence-revolution-how-artificial?utm_source=x&utm_medium=reply&utm_content=2048772578555166871&utm_campaign=the-convergence-revolution-how-artificial

🚨 MAX MARTIN & @C_ANGERMAYER SAY ENHANCED WILL BE 'READY TO GO' AS SOON AS THE FDA MOVES PEPTIDES TO CATEGORY 1
"The goal is to be ready immediately after, yes."
"Because think about it like this: What actually happens is that when 503A pharmacies are again able https://t.co/CfOcR1hFRK
The "ready to go immediately after" framing is doing a lot of work here, and the timeline math doesn't support it.
A favorable PCAC vote in July 2026 still trails Federal Register publication by a minimum of four months under normal conditions, and closer to 12-18 months if full notice-and-comment kicks in. So "immediately after FDA moves" conflates two very different events: the advisory vote and the actual legal change.
The harder problem is which peptides. If Enhanced's model depends on BPC-157 or TB-500, the October and December 2024 PCAC votes already went against bulks-list inclusion, and FDA's objections there were scientific, not political. Kennedy's Rogan announcement changed nothing about those votes. I mapped this out in detail at https://www.onhealthcare.tech/p/the-category-2-peptide-unwind-how?utm_source=x&utm_medium=reply&utm_content=2048790775690138072&utm_campaign=the-category-2-peptide-unwind-how because the GLP-1 wind-down is the direct model for how this plays out commercially.
New entrants face 503B registration timelines of 18-24 months. Incumbents absorb the volume. That is exactly what happened with semaglutide and tirzepatide compounding after shortage resolution.
"Ready to go" only pencils out if the right molecules clear. That part is far from settled.
In vivo CRISPR's first-ever ph 3 win!
@intelliatx lonvo-z hit primary + all key secondary endpoints in a ph3 study evaluating one-time treatment of pts with the rare genetic disease hereditary angioedema (HAE). One dose, 87% reduction in attack rate vs placebo, 62% of pts
The commercial math on this just changed. A single Phase 3 win for an in vivo CRISPR asset is exactly the kind of clinical anchor the FDA's new Plausible Mechanism Framework was built to amplify, because under the PMF's modular variant logic, that one trial can now support approval across a defined mutation set without separate studies for each variant. That's not a minor procedural footnote, it's a platform multiplier most investors haven't modeled yet. https://www.onhealthcare.tech/p/the-fda-just-rewrote-the-rules-for?utm_source=x&utm_medium=reply&utm_content=2048771845424652471&utm_campaign=the-fda-just-rewrote-the-rules-for
AI can now design antibodies that bind with atomic precision, but not ones that cells can produce. Our preprint closes this gap, delivering a structural principle, an AI-guided rescue pipeline, and adalimumab variants with 20-100x in vivo potency.
https://t.co/GvfgHA5EcU
The binding precision claim is real, but "in vivo production" is doing a lot of work in that framing. Cellular expression is not just a downstream step you bolt onto a design pipeline. Folding inside the ER, disulfide bond formation, glycosylation patterns, and secretion efficiency all constrain which sequences a cell will actually produce in useful quantities, and none of those constraints are fully captured by a structural model trained on purified crystallography data.
And the 20-100x potency range is a wide spread that suggests the structural principle is doing different amounts of work depending on the variant, which is the part I would want to understand before accepting the general claim.
This maps onto something I was looking at when analyzing the AlphaFold complex database expansion: predicted structures and actual biological behavior are separated by a confidence calibration gap that the field keeps underestimating. The 57,000 tentatively high-confidence heterodimer predictions in the new AFDB look like a large number until you ask how many reflect true binding geometry under physiological conditions. But precision of 0.859 on homodimers drops to unknown for heterodimers, and the same problem applies here. A structure can look right and still not fold, express, or bind the way the model predicts in a live cell.
The structural principle is the interesting contribution. The potency numbers are the claim that needs the most scrutiny before the gap is declared closed.

U.S. authorities have extended Medicare’s obesity drug pilot program into 2027, keeping coverage in place for $NVO 's Wegovy and $LLY 's Zepbound.
Bloomberg Intelligence says the near term impact for Novo Nordisk and Eli Lilly is likely limited, but the longer term opportunity
The Bridge extension getting framed as a win for NVO and LLY is the part that needs more scrutiny.
The Bridge keeps access alive, sure, but there's no Part D plan formulary behind it. CMS internally had this framing in place before the April 20 application deadline even closed, the April 21 HPMS memo was one day later for a reason. The 2027 Medicare story for these two companies is Medicaid, not Part D, and the state application window closes July 31.
For orforglipron especially, if it launches into this environment, it's entering a Medicare channel that has no structural coverage path until 2028 at the earliest.

What happened during the Change disaster?
Hospitals got bailed out.
CMS advanced $3.2 billion to hospitals between March and June 2024. UnitedHealth/Optum extended $6.5 billion in interest-liquidity through April 30.
Mercy, I looked it up, specifically had 218 days of cash
The bailout framing is doing a lot of work here that deserves some pressure.
CMS's accelerated payments in 2024 were essentially the same mechanism used during COVID, and hospitals have to repay them. That's not a bailout in any meaningful sense, it's a cash flow bridge against receivables that already existed. Mercy having 218 days of cash on hand actually cuts against the fragility story, not for it. A system with that reserve absorbing a claims processing interruption is evidence of resilience, not collapse.
The more revealing number from that period is what happened to the systems with 30 to 60 days of cash, the safety-net hospitals and rural systems that were genuinely exposed. They don't make the headline because they didn't need a bridge loan, they just quietly drew down reserves or deferred capital spending. No press release, no drama.
What the Change outage actually exposed wasn't that hospitals are fragile. It's that the entire claims infrastructure runs through a single clearinghouse processing roughly 15 billion transactions annually, and nobody had a credible failover. That concentration risk was known and tolerated because redundancy is expensive and competition in clearinghouse infrastructure is nearly nonexistent.
The $6.5 billion from UnitedHealth/Optum is the more interesting signal. A health plan subsidiary extending liquidity to the provider ecosystem it contracts with is a relationship that creates leverage, not charity.
I went through the broader structural picture in my UnitedHealth earnings piece if you want the mechanism behind why that dynamic persists: https://www.onhealthcare.tech/p/unitedhealths-2025-earnings-call?utm_source=x&utm_medium=reply&utm_content=2048717676264985058&utm_campaign=unitedhealths-2025-earnings-call
$IBRX
Here's a wild theory.
What if we're given FDA acceptance of sBla and PDUFA at same time and then it's announced after reviewing everything it's been determined we will be given rapid expanded access review under "plausible mechanism of action".
That may sound crazy https://t.co/POkZx4anH1
The reimbursement angle on that scenario is where it gets interesting. FDA acceptance plus PDUFA date is one thing, but if RAPID eligibility gets layered in, you're talking about CMS workflow triggering simultaneously with authorization, which is a completely different commercial event than the market usually prices. The five-year FDA-to-Medicare-coverage lag disappears as a risk variable, not because the evidence got better, but because the sequencing got fixed.
Does $IBRX even have the IDE study infrastructure with jointly agreed CMS-FDA endpoints that RAPID actually requires, though... https://www.onhealthcare.tech/p/the-cms-fda-rapid-coverage-pathway?utm_source=x&utm_medium=reply&utm_content=2048685705971569106&utm_campaign=the-cms-fda-rapid-coverage-pathway

WORLD’S FIRST PHASE 3 DATA FOR AN IN VIVO CRISPR THERAPY 🥇🌎 🧬
Lonvo Z for Hereditary Angioedema (HAE) $NTLA
Attack Rate Reduction 🟰87%
Rolling BLA submission initiated with the FDA.
Spaces today at Noon PT/3pm ET 🎙️ https://t.co/jvRpO9Km54
The 87% attack rate reduction is the headline but the BLA submission timing is what I keep coming back to. Intellia is walking into a regulatory environment that, as of early 2026, has a completely different architecture for how mechanistic evidence gets weighted in approval decisions.
The PMF changes the downstream math here in a way most coverage isn't picking up. If Intellia can establish the plausible mechanism link between their NTLA-2002 gRNA and KLKB1 reduction, subsequent variant additions don't require separate clinical trials. That modular logic under a single BLA could mean the Phase 3 data they just posted isn't just a product approval, it's a platform anchor.
The natural history data they've built around HAE attack frequency also becomes a reusable asset across any mutation-adjacent indication they want to expand into.

$REGN wins FDA approval for its gene therapy to treat a very rare genetic form of hearing loss. The company is giving away the therapy for free.
OTOF-related hearing loss affects approx. 50 newborns per year, so really rare, but... are there any concerns from other gene therapy
The OTOF approval is the proof of concept that the new PMF logic was built for. Fifty patients a year is exactly the cohort size where the old approval math broke down entirely, and the reason this got across the line is that the regulatory architecture finally caught up to the science.
The concern other companies should have is actually the opposite of what most are framing it as. The free pricing sets a precedent that will follow every ultra-small-cohort program through its commercial review, investors are going to ask that question on every call now.
What I'd push back on is the idea that the OTOF case is an outlier. I wrote about how the PMF's modular gRNA logic at https://www.onhealthcare.tech/p/the-fda-just-rewrote-the-rules-for?utm_source=x&utm_medium=reply&utm_content=2047359819078664269&utm_campaign=the-fda-just-rewrote-the-rules-for basically creates a replicable path for programs with patient pools this small, the commercial math only works if you treat the BLA as a platform asset and stack variants under it rather than running each one as a stand-alone program.
The real open question is who bears the off-target cost. Pre-IND NGS with full translocation analysis on a fifty-patient program is a brutal fixed cost, the unit economics only close if you're building toward a broader mutation set from day one.
Five fixable reasons your medicine takes so long to reach you:
1. Proving an osteoporosis drug works used to require enrolling 10,000+ women and waiting years to see who broke a bone. A simple switch, measuring bone density rather than fractures, reduced that to 500 patients in
The surrogate endpoint point is real but it understates how far the fix still has to go.
Getting from 10,000 to 500 patients is the easy part. The hard part is building the infrastructure to make those 500 patients defensible to a regulator, meaning clean phenotype data, valid comparators, and endpoints that map to outcome ontologies the FDA will accept. That work is mostly undone.
And when it is undone, drug developers are left trying to run lean trials on top of data systems that were built for a world where you just enrolled more people. The FDA's 2025 draft guidance on external control arms is essentially a spec sheet for infrastructure that nobody has fully built yet, which is what I got into here: https://www.onhealthcare.tech/p/clinical-trials-are-the-new-bottleneck?utm_source=x&utm_medium=reply&utm_content=2048471421329055748&utm_campaign=clinical-trials-are-the-new-bottleneck
But the surrogate endpoint story gets told as a win. In some ways it is. But it moves the hard problem, it does not remove it.
.@Health_Affairs published a new article co-authored by @dc_cavanaugh, chief policy officer, @Travis_Broome, SVP of policy & economics, and @Farzad_MD, co-founder and CEO. The piece makes the case for policies that will continue to incentivize and advance #ValueBasedCare, https://t.co/N2X1dKwAz4
The framing here is worth engaging with carefully. Policy incentives matter, but the actual bottleneck in commercial VBC right now isn't incentive design, it's operational infrastructure, and those are genuinely different problems requiring different solutions.
Medicare has spent roughly a decade building the tooling layer that makes MSSP and ACO REACH functional at scale. Commercial VBC is at maybe year two of that same build, except it's harder because you're not managing one payer's rules, you're managing Cigna's Collaborative Care logic simultaneously with Elevance's arrangements and Blue Shield's pay-for-value targets and BCBSMA's equity-linked quality contract, all with different attribution engines, different quality measure sets, and different specialty economics underneath.
Specialty spend is where this actually gets decided.
Cigna's own data puts cardiology, oncology, orthopedics, GI, and OB-GYN at 57% of medical spend inside their commercial VBC arrangements, which means primary care-centered policy frameworks are structuring incentives around the wrong financial frontier. The infrastructure gap for independent specialty groups operating across multi-payer commercial contracts is severe and mostly unaddressed by current policy conversations.
More incentive signals into a fragmented operational environment without solving the contract management and quality normalization layer just adds complexity to a system already collapsing under it.

Snap's survival tells you exactly what the durable asset was: 450 million teenagers who trained their social behavior around a specific interaction model, not the interaction model itself.
That maps directly onto what I've been arguing about healthcare software. The vendors who will survive the next two years of AI-driven build cost collapse are not the ones who built the most sophisticated prior auth logic or care gap engine. They're the ones who accumulated something that can't be reconstructed in six weeks with three engineers: longitudinal claims data linked to clinical outcomes, FDA clearance on a specific indication, or a decade of workflow integrations inside health system IT departments that would cost more to rip out than to keep. Snap's moat was behavioral lock-in and demographic penetration. Health tech's equivalent is data depth, regulatory standing, and embedded clinical relationships.
The companies that should be scared are the ones whose pitch to their last funding round was essentially "we encoded the business rules and nobody wants to rebuild it." That rebuild cost just dropped 90 percent.

AI could, in theory, automate 57% of US work hours. Yet most human skills remain relevant.
The future of work is not human or machine – but a partnership between people, agents, and robots.
Read our latest research on skill partnerships in the age of AI: https://t.co/h1K56uPqPo https://t.co/LNWeRQLfz8
The 57% theoretical automation figure is the easy part of the story. The harder number is the gap between what AI can do in theory and what it actually does in practice, and in healthcare that gap is enormous. The Anthropic labor market data from March 2026 shows a 61-point spread between 94% theoretical exposure and 33% observed deployment for computer and math occupations, roles that are far less regulated than clinical ones.
That gap is where the real economic action is.
And in hospital operations specifically, closing even a fraction of it against a $700-900 billion annual labor expense base produces returns that dwarf anything happening in cleaner, less regulated sectors. The "skill partnership" framing is accurate but may actually understate how the value distributes across industries, because the sectors with the biggest regulatory moats between theoretical and observed exposure are also the sectors where closing that gap pays the most. Which raises the question of whether the partnership model looks the same in a hospital as it does in a law firm or a warehouse, or whether the path to it is so different that...

Watched a hospitalist spend 11 minutes waiting on a reasoning trace for a chest pain workup last week. The output was thorough. It was also wrong on the pre-test probability for PE.
That gap is the real problem. Searching and second-guessing is not the same as calibrated inference. A system that hedges across possibilities without maintaining a probability state across new data points is doing something closer to compression than diagnosis. The 58-year-old with chest pain and dyspnea in the ED needs Bayesian updating as each result lands, not a long recap of what PE looks like.
The 12 million adults misdiagnosed annually in the US are not being failed by slow documentation. They are being failed by a reasoning gap that "thinking mode" framing does not close, because the core architecture is still a next-token predictor optimized for pattern matching.
Mode switching at the point of care is a workflow choice. The harder question is what the model is actually doing when it "thinks," and whether that maps to how clinical inference actually works. My read is that it does not, at least not yet.

Dive into Claude Code: The Design Space of Today's and Future AI Agent Systems
The paper explains the architecture of a modern production-grade AI agent system (Claude Code) by analyzing its source https://t.co/PZfbcrDb7R
The part of this that doesn't get enough attention is what production memory architecture actually costs you when you skip it. Everyone's focused on the agent loop itself, context windows, tool counts. The quiet failure mode is downstream: a system that retrieves well but never resolves contradictions between what it learned last Tuesday and what changed on Friday.
KAIROS (referenced over 150 times in the Claude Code source) isn't just a scheduler. It's a self-limiting interrupt system with a 15-second blocking budget. That design choice tells you something about the real tradeoff, which is that proactive agents without hard interruption budgets don't reduce cognitive load, they shift it.
Clinical AI has this exact problem. Alert fatigue in hospital systems runs above 90% override rates in some studies. The instinct is to add more human review. But the architecture question is actually whether your memory layer is generating stale or contradictory signals in the first place.
Consolidation before retrieval is the thing most health tech builders aren't doing (and won't feel the cost of until they're 18 months in and watching a competitor's system handle prior auth edge cases they can't). Naive RAG accumulates. It doesn't resolve.

Here is a video of me entering my office tomorrow knowing that $NTLA is about to present the first-ever Phase 3 data of an In Vivo (!) CRISPR Gene Editing Program. Somehow - and after @adamfeuerstein’s🧵👇- I have a feeling it won’t be the only BioTech and CRISPR news…🤔 $XBI https://t.co/lnKWPRO9qJ
The Phase 3 timing here is worth sitting with for a second. When I was working through the FDA's new Plausible Mechanism Framework earlier this year, one thing that stood out was how the five-element standard was written in a way that clearly anticipated programs exactly like NTLA's, where you have solid natural history data, a defined genetic target, and now clinical outcome data coming in from a real trial.
The piece of this that most people tracking $NTLA aren't focused on yet: the PMF explicitly allows a single adequate and well-controlled clinical trial plus confirmatory evidence to establish substantial effectiveness. That changes the read on Phase 3 data in a real way. If the NTLA results land clean, the path from here to approval is shorter than the old multi-trial standard would have required (and the modular gRNA variant logic means a clean BLA could extend to variant populations without separate trials).
The NGS safety guidance published in April also matters for how this data gets read on the safety side. Pre-IND off-target analysis requirements are now codified in a way that gives reviewers a clear checklist, which cuts both ways: it raises the bar for what gets submitted, but it also removes the ambiguity that used to slow down CBER review.
The broader CRISPR news angle you're hinting at makes sense given the regulatory architecture that just went into place. There are now actual commercial pathways where there weren't before.

HealthBench Professional, our new evaluation of clinician chat tasks, is now available on HuggingFace for easy access.
Each example was written, reviewed, and adjudicated by three or more physicians. We sampled heavily for difficulty for recent OpenAI models, so the evaluation
The difficulty-sampling detail is the part worth sitting with. When you weight toward harder cases, you're building a benchmark that tells you something real about ceiling performance, but it also means the score distribution gets harder to read for anyone trying to use it as a pass/fail signal for deployment.
And that's the gap I kept running into when I looked at how startups might actually use HealthBench in a commercial context. The benchmark works as a research tool, it works less cleanly as a credentialing mechanism, because "performed well on hard cases" and "safe to deploy in a clinic" are different claims. Procurement teams at health systems don't always have the stats background to parse that gap, which means the benchmark's value as a trust signal depends heavily on how the score gets communicated, not just what the score is.
The three-physician review per example helps, but does physician agreement on what a good answer looks like in a chat scenario actually transfer to how a model performs when the clinical context is noisier or the user is a patient rather than a clinician? That's where the professional versus consumer split starts to matter a lot for anyone building a product on top of these scores.

Perspective by Sara Gerke, Dipl-Jur Univ (@gerke_sara), @ravi_b_parikh, MD, MPP, and I. Glenn Cohen, JD (@CohenProf): Utah’s Prescription-Renewal Pilot Program — Autonomous AI Managing Patient Care https://t.co/wNprS5MErM
#ArtificialIntelligence #MedicalEthics https://t.co/fgYYk1aHk9
The Utah pilot is where the liability question gets unavoidable. When an autonomous system renews a prescription and something goes wrong, the accountability chain collapses in ways that current medical malpractice frameworks simply were not built to handle (the physician who never reviewed the renewal, the vendor whose algorithm made the call, the payer who incentivized automation to cut costs).
What the pilot surfaces, though, is a separate architectural problem that the ethics debate tends to skip past. The AI doing the renewal is still working with the same static drug interaction logic and generic contraindication rules that legacy e-prescribing systems have always used. Autonomy layered on top of a rule-based foundation does not get you personalized prescribing. It gets you faster generic prescribing, which is a different thing entirely.
The more consequential version of this, the one where pharmacogenomics data and patient-specific response history actually inform what gets renewed and at what dose, requires infrastructure that incumbent platforms cannot retrofit. Surescripts moves transaction volume. RXNT handles compliance workflows. Neither was designed to ingest genetic profile data and run it through models that adjust dosing based on observed outcomes over time. So the Utah pilot, whatever its ethics conclusions, is operating inside a ceiling that the underlying technology set.
The real disruption question is whether AI-native architectures with outcome-based pricing can replace that foundation rather than automate on top of it. I looked at exactly this in the context of e-prescribing incumbents and where the structural opening actually sits: https://www.onhealthcare.tech/p/ai-driven-e-prescribing-disrupting?utm_source=x&utm_medium=reply&utm_content=2048507473490034828&utm_campaign=ai-driven-e-prescribing-disrupting
it is also a responsibility game.
my dad is a robotic cardiac surgeon. he has been using robots since 2002, almost my entire life. if a surgeon trusts the robot to do the work, who exactly is responsible legally? no. he uses the robot to do his work more precisely.
AI drug
The surgical robot analogy actually breaks down fast when you get to diagnostic AI, though. A robot arm doesn't independently flag a lesion as benign or recommend against biopsy. When the AI does that and the physician follows it, the accountability chain gets genuinely murky in ways that 2002-era robotic surgery never had to resolve.
The vendor still gets paid either way. https://www.onhealthcare.tech/p/nobody-gets-sued-but-the-doctor-the?utm_source=x&utm_medium=reply&utm_content=2048432678857519168&utm_campaign=nobody-gets-sued-but-the-doctor-the
The smartest ideas in healthcare AI come from people who understand both sides: • How clinicians make decisions • Where workflows actually break • What data is reliable • What ethics look like in practice Real insight comes from lived experience (not theory). — Bhargav Patel, MD, MBA (@doctorbhargav) April 26, 2026
The frustrating part is that "lived experience" gets operationalized as clinician advisory boards, which almost never surface the actual breakdown points. A physician can tell you how a prior auth decision should work. But they usually cannot tell you that the approval queue lives in a SharePoint folder that three people have inconsistent access to, or that the informal criteria the payer actually uses got communicated via a single email chain from 2021 that no one has codified.
That gap, between how workflows are supposed to work and how they actually run, is what I spent a lot of time on at https://www.onhealthcare.tech/p/the-standardization-trap-why-deploying?utm_source=x&utm_medium=reply&utm_content=2048401732636397570&utm_campaign=the-standardization-trap-why-deploying, and the finding that stuck with me is that you cannot extract this through interviews. You have to be embedded long enough to watch the workarounds happen in real time.
And the companies failing at enterprise conversion are almost uniformly the ones who thought clinical advisory input was a substitute for that. The knowledge you need to encode is not in anyone's head in a retrievable form, it's distributed across habits, exceptions, and legacy decisions no one remembers making.
Which raises a harder question: if even the clinicians closest to a workflow cannot fully articulate it, what does "lived experience" actually transfer when someone moves from practice into a health AI company?
This is just two GLP-1s, one peptide, one use case
what happens when off-label prescribing ramps up
what happens when retatrutide hits the market
what happens when other peptides become compoundable
chapter one
The "chapter one" framing is right but the timeline people are building around it is off by at least a full regulatory cycle.
The compounding piece specifically, everyone is anchoring on Kennedy's February podcast appearance as if that changed the legal status of anything. It didn't. The actual decision point is the July 2026 PCAC meeting, and the October and December 2024 votes already went against bulks-list inclusion for six peptides. FDA follows those recommendations at 80%+ historically. That's not a political headwind, that's a pre-determined outcome absent new clinical data.
And the molecules getting the most commercial excitement, BPC-157 and TB-500, are the ones with the weakest cases. FDA's objections there are immunogenicity and an evidence base that's almost entirely rat tendon models. That doesn't get resolved by a podcast or a reconstituted advisory committee.
The GLP-1 unwind is the better template here. Peak compounded GLP-1 revenue was $6-8B across roughly 4-5 million Rx, and when FDA resolved the shortage declarations the 503B incumbents absorbed the volume because new entrants couldn't replicate the licenses and API relationships on any relevant timeline. Same dynamic is going to play out on the peptide side, which is why I'd look hard at who already has the infrastructure before assuming chapter two is open to new players.
What does the off-label ramp actually look like if three or four of the named peptides never clear Cat 2 at all?

The U.S. wasn't ready for ChatGPT. Are we repeating the mistakes with world models? “Policymakers, government officials — many of them don’t even know what a world model is.” @StanfordHAI Executive Director @russellwald said on @politico. Read more: https://t.co/hxxnPeq2dD
The policy gap is real, but healthcare might actually be the sector where it matters least in the near term. The highest-return applications for world models in health aren't clinical decision support, where FDA clearance and physician buy-in create massive friction. They're operational: OR scheduling, nurse rostering, ED throughput. Administrators control those budgets, the data is cleaner, and you don't need a regulator to understand latent-space prediction to approve your product.
Where the policy gap bites hardest is in clinical applications, and the reason is specific. World models derive their value from counterfactual reasoning, simulating forward trajectories under different interventions rather than just flagging risk. That capability is exactly what current FDA clearance frameworks weren't designed to evaluate. Policymakers who don't know what a world model is can't distinguish a sepsis risk score from a system that reasons about whether aggressive fluid resuscitation helps or harms a particular patient. Those are architecturally different problems, not just better versions of the same thing.
The ChatGPT parallel also cuts a different way than the post implies. The scramble after ChatGPT produced a wave of generative AI in healthcare built on models trained to maximize likelihood of observed data, which encourages memorization of surface statistics rather than causal structure. Scaling that approach on EHR data won't produce clinical reasoning. Policy catching up to world models while investment dollars still flow to generative health AI means we'd be regulating the right thing while funding the wrong one.

Yesterday, I joined @shawnzeller at the @POLITICOLive Health Care Summit to discuss what’s at stake for patients and the future of biopharma. We need to push other countries to pay their fair share and also fix misaligned incentives, including PBMs and 340B. #POLITICOHealth https://t.co/JbvFqX2wjW
The 340B and PBM reform pairing keeps showing up together on conference panels, but the structural problem connecting them rarely gets named directly: both programs create conditions where the financial benefit flows somewhere other than the patient who is actually sick.
In the PBM case specifically, the gross-to-net spread means patients in deductible phases pay wholesale acquisition cost while the rebate revenue lands with employers and the PBM. The sicker you are, the more of the year you spend in that deductible window, which makes the rebate system quietly regressive in ways that don't show up in any transparency report.
Spent some time pulling this apart through the Cuban-Conway debate at Hopkins, where Conway's 100% passthrough claim holds up technically but collapses practically the moment you ask which legal entity is passing through to whom.

Hims & Hers $HIMS Just Announced an Expansion of Eli Lilly $LLY Weight Loss Drugs💊
Providers can now send prescriptions for Zepbound, Mounjaro, KwikPens & more straight to Lillydirect pharmacy!
Hims is now collaborating with two key partners, $NVO & $LLY https://t.co/tkdC8BRewh
Lilly's Employer Connect program priced Zepbound KwikPen at $449 per dose through direct channels, and the Hims expansion fits that same architecture: manufacturers routing volume through platforms that have patient relationships baked in, bypassing the rebate negotiation layer entirely.
What makes the Hims angle sharper than a typical direct-to-consumer story is that Hims already owns the prescriber relationship (through its telehealth layer), which means PBMs are getting cut out at both ends, the adjudication side and the relationship side. That's a different kind of threat than a cash-pay pharmacy discount.
The question worth sitting with is what happens to employer plan designs when their covered employees are sourcing GLP-1s through Hims or LillyDirect outside the benefit entirely. Employers are already reporting 66% significant spend impact through their managed channels (per KFF 2025 data), but that math assumes the utilization is visible to the plan. If patients increasingly go around the benefit, the employer loses the adherence management, the behavioral gates, the outcomes data, everything the new operating model was supposed to capture.
Novo's parallel direct channel launched January 1, 2026, and Lilly's Employer Connect followed in March, and now Hims is threading both. That's a pretty compressed timeline for what amounts to a structural bypass of PBM intermediary value. The persistence problem (only 1-in-12 patients still on therapy after three years in Prime Therapeutics data) doesn't go away just because the distribution channel changes, which makes me wonder whether any of these platforms are actually solving for...

Prices for the same medical procedure can vary dramatically depending on where care is delivered, in some cases by as much as 10 times (1,000%).
Surgery Center of Oklahoma's commitment to transparent, bundled pricing and direct payment means that our patients pay less for https://t.co/lwfZL0maNh
The 500% rate variation for the same MRI at the same facility across commercial insurers, which I documented from Health Affairs data, is actually the conservative end of what you're seeing in surgical procedures. The variance isn't random noise. It's the output of a system where opacity is load-bearing.
That's the part most transparency advocates miss.
Bundled cash pricing works, and Surgery Center of Oklahoma proves it, but the mechanism doing the damage isn't really pricing complexity. It's that contracted rates are confidential by design, which means no employer CFO can tell you what their insurer actually paid last quarter for the procedures their employees had. The EOB arrives after the fact, stripped of the information that would let anyone shop. Transparency tools that surface real prices before care is delivered don't just help patients save money. They start to dissolve the information asymmetry that makes the commercial rate stack possible in the first place.
What I've been working through is what happens when you aggregate enough of that pre-care price data at scale, particularly across self-funded employer plans where the plan sponsor has legal access to claims data they've never actually used. At some threshold of covered lives routing through direct-pay arrangements, providers can't afford to treat cash-pay patients as the exception anymore.
The real question is whether employer adoption of HRA-plus-direct-pay structures moves fast enough that insurers can't reprice or restructure their contracts before the defection becomes...

Major insurers are moving to exclude AI-related damages from standard liability policies, with regulators approving most requests. The shift could force companies to rethink who bears the risk when AI systems fail.
Read more: https://t.co/Uh5tVdkIJN
The rethinking is already happening in clinical AI, but it's moving in a direction most vendors haven't priced in. Right now, AI diagnostic tool companies clear FDA review, deploy into hospitals, and then contractually push all liability onto physicians through standard SaaS indemnification clauses. The insurer exclusions you're describing will accelerate that reckoning, because they remove the last financial buffer between vendor contracts and direct exposure.
But the physician end of this is already buckling. Malpractice claims involving AI tools rose 14% between 2022 and 2024, and coverage conditions are shifting: some insurers now require AI-specific training as a prerequisite for coverage. Doctors are absorbing risk for tools they didn't build, can't audit, and in some cases can't safely stop using, because deskilling effects mean removing the AI makes performance worse.
The structural problem is that 97% of cleared AI medical devices came through the 510(k) pathway, which was designed for incremental hardware changes, and most vendors treat that clearance as liability insulation. It isn't. The first successful product liability case against a clinical AI vendor will reprice the entire category.
The companies that build accountability infrastructure now, transparency documentation, performance thresholds written into contracts, post-market monitoring, will have defensible positions when that case lands. Everyone else will be renegotiating from a weak hand.
I went deep on this dynamic specifically in clinical AI: https://www.onhealthcare.tech/p/nobody-gets-sued-but-the-doctor-the?utm_source=x&utm_medium=reply&utm_content=2048432166372032961&utm_campaign=nobody-gets-sued-but-the-doctor-the
AI is taking on more of the labor.
It is not taking on the accountability.
@danielnewmanUV and @GregLotko talk with @Darren_Surch of @Interskil about why mainframe teams now have to interpret and stand behind AI-driven outputs, and why organizations that stop investing in https://t.co/WeBSSBMSVr
The ACCEPT trial data I keep returning to makes this concrete: endoscopists using AI for polyp detection saw their own adenoma detection rate drop from 28% to 22% the moment AI was removed. So the physician absorbs deskilling on the way in, then absorbs full liability on the way out.
That gap (labor to AI, accountability back to human) is exactly the structure I mapped in clinical AI, and it runs the same direction in mainframe environments. The vendor takes the output credit. The operator takes the legal exposure.
What makes medicine a sharper case is that 97% of AI medical devices cleared FDA via the 510(k) pathway, which was designed for hardware tweaks, not adaptive algorithms. So you have tools that retrain continuously, contracts that push all liability to physicians, and regulators who haven't caught up. The accountability gap has a paper trail and nobody is named on it.
Organizations that stop investing in the human capacity to interpret and challenge AI outputs are not just creating a skills problem. They are building a liability structure where no one inside the organization can credibly say they exercised independent judgment.
That is the exposure. https://www.onhealthcare.tech/p/nobody-gets-sued-but-the-doctor-the?utm_source=x&utm_medium=reply&utm_content=2046981590249582632&utm_campaign=nobody-gets-sued-but-the-doctor-the
Drug discovery didn’t hit a wall. It just stopped looking in one of the most important places: nature. Nature wasn’t abandoned because it lacked value. It was just too hard to analyze.
For years, pharma moved toward biology-first approaches that felt more predictable. In the
That shift away from natural compounds is a real loss, but the "too hard to analyze" framing raises the more interesting question: how much of that difficulty was irreducible biological complexity versus a genuine gap in analytical tools?
My instinct is it's mostly the latter. The math and physics we now apply to biological systems, fractal modeling of molecular binding geometries, differential equations tracking metabolite behavior through ADME pathways, quantum tunneling effects in enzyme catalysis, these weren't mature enough to make natural compound libraries computationally tractable. The complexity was always there, we just couldn't describe it precisely enough to work with it.
The harder problem is that even with better tools, natural products sit at the messiest end of biology's uncertainty spectrum. A synthetic compound behaves predictably across populations, a plant-derived molecule carries evolutionary context, metabolic variability, structural analogs that interact with targets in ways no clean pharmacokinetic model fully captures. That's not a failure of the model, it's what biological systems actually do.
So I'd push back slightly on the "just too hard" read. Pharma moved toward biology-first approaches partly because those systems felt controllable, the math worked cleanly. Natural compounds didn't disappear because we lacked interest, they disappeared because probabilistic unpredictability is expensive at scale.
AI-driven screening is changing that calculation, it can hold more variables, but the underlying biological noise doesn't go away.
I've been writing about exactly this tension between mathematical precision and biological irreducibility: https://www.onhealthcare.tech/p/mathematics-physics-and-life-sciences?utm_source=x&utm_medium=reply&utm_content=2047422640860610628&utm_campaign=mathematics-physics-and-life-sciences
America health insurance is a scam
“So you're telling me I've been paying a $75 co-pay for physical therapy with my insurance, but if I do self-pay, it's $60 a session”
Keep in mind, this is on top of monthly premiums
The real kicker is if you have health insurance then doctors offices won’t allow you to pay the cheaper cash price
The reason for this is, if they let you pay the cheaper cash price the insurance companies will actually remove them from being an in-network provider. They’ll void their contracts
It’s a racket
That last point is the one most people miss, the in-network contract itself is what enforces the pricing floor. Providers aren't choosing to charge you more because you have insurance, they're contractually prohibited from offering you the lower rate, and violating that clause gets them kicked off the network entirely.
This is exactly the mechanism I mapped in my piece on healthcare pricing opacity: the insurer's leverage isn't claims processing, it's the threat of network exclusion, which means the "benefit" of insurance can literally cost you money on routine care while the premium clock keeps running.
The data asset sitting underneath all of this is the contracted rate sheet itself, every time a patient uploads an EOB, you get another data point on what the insurer actually negotiated, and at scale that reverse-engineers the pricing black box that the whole system depends on staying closed. https://www.onhealthcare.tech/p/the-accidental-death-of-healthcare?utm_source=x&utm_medium=reply&utm_content=2048076165202768190&utm_campaign=the-accidental-death-of-healthcare
AlphaFind v2: Similarity search in AlphaFold DB and TED domains across structural contexts
1 AlphaFind v2 is a web server for fast, structure-based similarity search at AlphaFold DB scale, combining embedding-based prefiltering with alignment-based refinement to keep results https://t.co/e1e8XznIcH
The search layer is useful. But here's where I'd push back slightly: once you can retrieve structurally similar complexes at scale, the next problem is that the confidence metadata attached to those retrieved structures is inconsistent in ways that matter for downstream use (particularly for heterodimeric hits, where the field doesn't yet have a validated calibration framework).
I looked at this when writing about the AlphaFold DB expansion to 31 million predicted complexes. Of the roughly 7.6 million heterodimer candidates drawn from STRING physical interaction annotations, only 57,000 passed tentative high-confidence filters. That's less than 1%. And even those are almost certainly a biased sample, skewed toward well-studied organisms and interaction types with dense experimental annotation. So when AlphaFind v2 returns a heterodimer hit with high structural similarity, the question of whether that retrieved complex is actually a trustworthy model is still largely open (the precision-recall tradeoff at the confidence thresholds used gets complicated fast).
The search infrastructure is getting genuinely good. The interpretation layer is not keeping pace. Which raises the question: for drug discovery teams using similarity search to find structural analogs of target complexes, how much of the retrieved set are they actually equipped to triage?

People who want fully AI doctors are gunna be pretty upset when they realize that AI will order far LESS testing than human doctors. US docs orders far more labs, imaging than most other countries (often not indicated or for fear of malpractice). And you won’t be able to talk an
The question that actually haunts this is: who benefits most when AI rationalizes utilization, and does that efficiency get passed to patients or captured upstream by plans?
When I dug into the utilization management side of healthcare costs, the pattern I kept running into was that reducing volume in one category reliably shifts costs elsewhere. Care management programs show 15-25% reductions in hospital admissions among enrolled members, but the total medical cost impact often lands at 3-8%, because the system finds other outlets. An AI that cuts imaging orders by 20% might just surface unmet demand in a different service category, or compress costs in ways that look clean on a dashboard but obscure what happened downstream.
There's a harder structural problem underneath this.
The bigger issue for health tech entrepreneurs isn't whether AI will reduce utilization, it almost certainly will in targeted categories. It's whether that reduction creates any durable competitive advantage, and my analysis of utilization management broadly suggests it probably doesn't at scale, because the clinical logic requires constant local calibration against specific provider networks and population risk profiles. A model that works in Minnesota fails in Florida for reasons that aren't fixable with more data.
What I find more interesting is what happens to the unit cost side of the equation if AI simultaneously makes providers more defensible by surfacing documentation that justifies higher coding levels. The 300-400% price variability for identical procedures within the same market doesn't close just because volume drops, and an AI ordering fewer tests could theoretically coexist with per-unit costs continuing to drift upward if the payment integrity side isn't addressed in parallel. Which raises the question of whether AI utilization management and AI-driven price benchmarking are on a collision course or...

We need to start tracking the provenance of clinical text *now*.
We must be able to know which words were WRITTEN by the physician, which were merely approved, and which were not reviewed at all.
Are AI scribe notes good or bad? Soon we may not be able to even evaluate this.
The evaluation problem is real, but the architecture to solve it already exists. The gap is that most EHR integrations treat AI scribe output as terminal text the moment it lands in the note field, which collapses exactly the provenance chain you need to answer the written vs. approved vs. ignored question later.
What makes this harder than it looks: LLM outputs are stochastic, so even capturing the final note text isn't enough. You need the prompt parameters, model version, and timestamp at generation time, or two notes that look identical could have been produced under completely different conditions. I worked through the full architecture problem at https://www.onhealthcare.tech/p/ai-and-llm-data-provenance-and-audit?utm_source=x&utm_medium=reply&utm_content=2048093529550082349&utm_campaign=ai-and-llm-data-provenance-and-audit and the scribe use case sits right at the intersection of Joint Commission monitoring standards and HIPAA audit log requirements for PHI transformations.
The window to build this in at the infrastructure level is closing fast. Once AI-generated text is the default and physician-written text is the exception, reconstructing that distinction retroactively becomes nearly impossible.
There are incredible oncologists and exciting breakthrough therapies that are meaningfully extending life but having been on the other side of ICU care (thankfully I’m not doing this work anymore) I resonate with this post. It should be essential that all oncologists be highly… https://t.co/Sw21ENk4PV — Michael Mindrum, MD (@MichaelMindrum) April 26, 2026
The clinical instinct here is right, but the bottleneck isn't just oncologist training or communication culture. Even when an oncologist has the conversation, what happens to the document? It gets printed, signed, filed somewhere, and then is completely invisible to the ED team at 2am when the patient arrives by ambulance. That gap between conversation and actionable directive is where the system actually breaks down.
And the paper-based fragmentation makes it worse than most people realize. State-by-state variation in witness requirements, proxy designation formats, and legal validity means a directive completed in one state may be unenforceable in another, which is a structural problem no amount of better communication training fixes on its own.
The value-based care shift is creating real financial pressure on health systems to close this loop, which is why I've been arguing that EHR integration via HL7 FHIR and cloud-native document architecture aren't technical niceties here, they're the actual mechanism that makes a completed advance directive matter at the point of care rather than sitting in a folder nobody can find. The conversation is necessary but not sufficient without the infrastructure to make the document follow the patient.

Boulder City Hospital's leadership have been crystal clear: they are having to cut services and lay off workers because of Trump and Republicans' Medicaid cuts.
I asked RFK Jr. what he's doing to protect rural communities like ours in Nevada. Once again, he had no real answers. https://t.co/HkJ9YnzYmd
Boulder City is a preview, and the financing mechanism driving it is more specific than "Medicaid cuts."
State directed payments are being capped at 100 percent of Medicare rates for expansion states. A safety net hospital getting 70 percent of its revenue from Medicaid, with a chunk flowing through directed payments previously set at 150 percent of Medicare, sees overall reimbursement drop from roughly 120 percent to 95 percent of Medicare. That gap is not recoverable through operational efficiency. It shows up as service cuts and layoffs, exactly what Boulder City's leadership is describing, and the cap does not phase in gradually enough to allow meaningful adaptation.
RFK has no answers because HHS does not control this. The fiscal architecture was written into reconciliation and the provider tax freeze locks states out of their primary workaround.

The benchmark numbers on something like this are almost always the least interesting part. What matters is whether the variant-level predictions hold when you move from the well-characterized training populations to the actual clinical mix, which skews heavily toward understudied ancestries and edge-case phenotypes (the populations where roughly half of disease-associated variants still sit in uncertain significance territory).
The "unifies" framing in the headline is doing a lot of work. Integration at the model level and integration at the clinical workflow level are completely different problems, and the second one doesn't get solved by better architecture.
Reimbursement and hospital IT are where these frameworks go quiet.

The core problem is structural, not just bureaucratic. When your eligible population is a few thousand patients spread across a decade of onset windows, you literally cannot randomize your way to a traditional pivotal trial, the math doesn't work, and everyone in the system knows it.
What changed in February 2026 (and what most people tracking $QURE haven't fully processed) is that the FDA's Plausible Mechanism Framework explicitly contemplates this scenario. A single adequate and well-controlled investigation plus confirmatory evidence, including natural history comparator data, can now establish substantial effectiveness. That 75% slowing figure you're citing is exactly the kind of clinical outcome signal the PMF's five-element standard was built to evaluate without demanding a parallel randomized arm that's impossible to populate.
The piece I published on this goes further into something the Huntington's community should care about specifically: the modular variant logic. If a platform like uniQure's gets an initial approval for one mutation set, subsequent gRNA variants targeting related pathogenic alterations can potentially bridge through mechanistic plausibility rather than fresh trials (which means the approval pathway for HD's genetic heterogeneity looks materially different than it did 18 months ago).
The zero urgency framing is accurate for the old regime. Whether it holds under the new architecture is a different question entirely.

$71B is a manufacturing constraint, dressed up as a revenue number.
Lilly and Novo have run production 24/7 for two years and still ration supply. Lilly committed $50B+ to US manufacturing since 2020. Novo paid $11B for three Catalent fill-finish sites in 2024 specifically
The supply crunch is real. But rationing is also a pricing mechanism, not just a logistics failure.
When Novo keeps injectable semaglutide tight, oral formulations look like relief. They're not. Oral sema's bioavailability sits around 1 percent, which means you need far more active compound per dose to hit the same effect. That actually deepens the manufacturing burden per patient, not reduces it.
The constraint shifts, it doesn't disappear.
What I'd push on: the Catalent acquisition tells you something about where Novo thinks the bottleneck lives long-term. Fill-finish capacity, not synthesis. That's a bet on volume, which is a bet on oral and biosimilar coexistence, not injectable dominance continuing forever. The $11B wasn't defensive. It was a land grab for the oral transition infrastructure before biosimilar entry around 2031-2033 forces price compression anyway.
The deeper problem for Lilly and Novo is that capital deployed at this scale locks them into injectable economics right when oral bioavailability tech is improving fast enough to matter. Manufacturing moats can become anchors.
Durable value in this space won't live in the molecule or the vial. It accretes in clinical evidence estates, cold chain systems, and the data that proves which patient on which formulation stays on therapy longest. That's where I'd be looking.

This session, Tennessee joined @realDonaldTrump’s mission to stand against healthcare monopolies. For far too long, vertically integrated PBMs have savaged the marketplace. They control all aspects of the market and as they drive up costs, and force independent pharmacies out of
The question this raises that nobody seems to want to answer: does forcing PBMs to divest pharmacy assets actually lower drug prices, or does it just redistribute margin?
Arkansas got closer to an answer in 2025. Their ban on PBM-pharmacy ownership produced an estimated 7.1% drug price drop. That's not from price caps or new rules, that's from removing the structural conflict that let PBMs route claims through owned pharmacies at markups the FTC found reached 7,736% above drug cost for some specialty generics, generating over $7 billion in excess revenue from 2017 to 2022.
The consolidation you're naming in Tennessee fits a pattern I traced back to the ACA's medical loss ratio rule. When insurers had to spend 80-85% of premiums on medical care, owning the pharmacy and the clinic meant that spending still counted toward compliance. The vertical stack wasn't just about market control, it was a regulatory arbitrage play from the start.
So the real pressure point for state-level action isn't oversight or pricing rules. It's ownership separation. Which raises the harder question: if Tennessee prohibits PBM-pharmacy ownership the way Arkansas did, who actually builds the independent pharmacy infrastructure to absorb what gets divested, and at what speed?

$LLY ’s Mounjaro will not be listed on Australia’s PBS after pricing negotiations collapsed.
Eli Lilly walked away from talks with the government, leaving around 450,000 patients without subsidized access.
Patients will continue to pay hundreds of dollars per month out of
The Australia PBS collapse is actually a useful data point for reading the US MFN structure, because Lilly's willingness to walk from a public payer negotiation abroad tells you something about where their floor is.
But the US deals didn't happen because manufacturers suddenly became cooperative. The tariff-plus-rulemaking threat package made voluntary compliance the rational choice, and that's a different negotiating dynamic than what PBS runs. Australia had no equivalent coercive backstop, so Lilly could walk without consequence.
What the US program still hasn't solved is the infrastructure side. The $245 Medicare and Medicaid price for Mounjaro and Zepbound is now a public benchmark, but there's no published contract text, no MFN formula, no state Medicaid reconciliation guidance. Commercial plans paying above that number are exposed on ERISA fiduciary grounds and most of them don't know it yet.
And TrumpRx, the only live artifact of actual US pricing commitments, lacks eligibility verification, prescriber workflow integration, and secondary payer coordination. It's a price list, not a functioning access layer.
The 450,000 Australian patients without subsidized access are paying the price of a negotiation that had no enforcement backstop. The US avoided that outcome structurally, but the compliance and adjudication infrastructure to actually deliver access at scale hasn't been built.

An ONC and @samhsagov pilot in Connecticut is advancing electronic consent management for sensitive data sharing—helping enable more coordinated, privacy-protective care. The work also highlights the role of USCDI+ in supporting more consistent, scalable data exchange. Read more
The Connecticut pilot is doing real work, but the USCDI+ framing here deserves a closer look. USCDI+ is a use-case-specific layer that sits outside the mandatory certification floor, which means adoption stays voluntary unless CMS or another payer ties it to a payment or participation condition. That's a meaningful distinction when you're thinking about scale.
And the consent management piece is where things get genuinely complicated. Consent for 42 CFR Part 2 data has historically broken interoperability workflows precisely because EHRs couldn't propagate consent status downstream through FHIR API calls in any consistent way. A state-level pilot can demonstrate the technical pattern without resolving the hard part, which is what happens when that consent object crosses system and organizational boundaries with different policy interpretations.
I was already writing about this structural gap when I looked at the 2026 ISA outputs, specifically how USCDI v7 is expanding the mandatory data element floor to 156 proposed elements (from 52 in v1) while the sensitive data categories most relevant to behavioral health remain in voluntary USCDI+ territory rather than the mandatory core. You can see the argument at https://www.onhealthcare.tech/p/the-2026-isa-onc-drops-a-catalog?utm_source=x&utm_medium=reply&utm_content=2047035459793027506&utm_campaign=the-2026-isa-onc-drops-a-catalog
The pilot matters. But the distance between a successful state consent pilot and nationwide interoperable consent propagation is where most of these initiatives quietly stall. The standards exist. Consistent implementation does not.

Not going to stop until it’s as easy to start a biotech startup on GCL as it is to start a software startup on AWS. https://t.co/GDEyT1pI7F
The 300,000 to 100,000 antibody candidate funnel MSK ran through Bio Discovery happened in weeks, not the typical year-plus, and the reason that matters for what you're building is the handoff. The in silico to wet-lab gap is where institutional knowledge has always died, every experiment that doesn't feed back into the model is a compounding loss, and closing that loop is what actually changes the economics.
But AWS entering this space with outcome-based pricing and pre-existing relationships with 19 of the top 20 pharma companies means the platform war is arriving faster than most biotech founders have priced in. The question won't be which biological foundation model is better, those are already commoditizing, it will be who owns the compounding data loop that each lab cycle generates. That's the real stakes behind making biotech as accessible as a software startup, whoever controls the infrastructure controls the knowledge accumulation.

💬 Viewpoint: The widespread use of #AI for residency application screening in US graduate medical education programs introduces new legal and ethical concerns, particularly regarding disparate impact discrimination and unvalidated subgroup performance.
https://t.co/WBeGQmkBr1 https://t.co/4Xjc1hJG1f
The disparate impact risk is real, but the validation problem runs deeper than most program directors realize. The JAMA Network Open cross-sectional study I looked at found that among 903 FDA-cleared AI devices, under 25% addressed age subgroups and less than a third provided sex-specific performance data, and that's for clinical diagnostic tools where the FDA at least requires some evidence of safety before clearance. Residency screening AI faces no equivalent regulatory gate at all.
Which means the liability structure is arguably worse than in clinical AI, not better.
When a screening algorithm deprioritizes applicants from certain demographic groups and a program later faces an EEOC complaint or civil rights litigation, who absorbs that exposure? The residency program, almost certainly, because vendor contracts in this space are built the same way SaaS contracts in clinical medicine are built: indemnification flows downstream to the institutional user, liability stays with the human decision-maker who clicked approve. The vendor sold a tool, you made the choice (so the contract says). Program directors are inheriting the same no-win structure that physicians already navigate in diagnostic AI, where they face legal exposure whether they follow the algorithm's ranking or override it without documented justification.
The deeper structural problem is that unvalidated subgroup performance gets baked into consequential decisions before anyone builds the evidentiary record needed to defend those decisions in court. I wrote about exactly this liability arbitrage dynamic in clinical AI, and the residency screening context fits the same pattern almost perfectly: https://www.onhealthcare.tech/p/nobody-gets-sued-but-the-doctor-the?utm_source=x&utm_medium=reply&utm_content=2047994027824304138&utm_campaign=nobody-gets-sued-but-the-doctor-the
Almost all of my positions selling some kind of AI/agentic SaaS tool have (either by foresight or customer demand) pivoted to some kind of business model where they “forward deploy” to the customer first and then sell the system they create back to them as SaaS. 99% of “normie” businesses have 0 idea how to use AI tools to achieve their business goals
Imo most VCs are still behind on understanding this
The VC lag makes sense when you consider how the incentive structure works (high gross margins on pure software make the model look cleaner in a deck than "we embedded a team for six months"). But the companies hiding FDE costs behind professional services line items to keep their software metrics clean are making a compounding strategic error, because those embedded engagements are where the reusable workflow artifacts accumulate. That knowledge becomes proprietary. It does not look like software revenue, but it behaves like one of the most defensible assets in the stack.
In healthcare specifically, I found this plays out in a specific way: the 70% pilot failure rate has almost nothing to do with model capability and almost everything to do with what you're describing, which is that no one actually documented how the workflow runs before trying to automate it.
The question I keep coming back to is whether the VC framing ever catches up before the companies that got this right early have already compounded too far ahead to catch.

Foundayo (orforglipron) scripts off to a slow start both in raw numbers and in comparison to Oral Wegovy’s launch at same time point.
Overall statistics show Oral Wegovy script growth is robust, and thus far undeterred, by Foundayo market entry.
🎩 @bloomberg https://t.co/hCJUT5gH2B
The slow Foundayo start makes sense on the commercial side, but there's a Medicare coverage layer here that makes the 2027 competitive picture even harder to read than the script data suggests.
When CMS paused the Part D leg of the BALANCE Model on April 21 (one day after the application deadline closed, which tells you something about how marginal the miss wasn't), it effectively left both Lilly and Novo Nordisk holding negotiated model terms with no Part D deployment channel to run them through. Orforglipron is the product most exposed by that outcome. It would be launching into a Medicare environment where the GLP-1 Bridge extension has become the de facto 2027 coverage policy, but the Bridge was structured around existing injectable products and the Appendix C net price anchor of $245 per month for Zepbound KwikPen. Oral formulations weren't priced into that framework with the same clarity.
The script comparison to oral semaglutide also omits the Medicaid dimension, which is where the actionable near-term volume story actually lives. The BALANCE Medicaid leg avoided the coordination failure problem that killed the Part D threshold (the 80 percent NAMBA-weighted requirement that needed simultaneous buy-in from essentially every major sponsor), and states can enter on a rolling basis through the July 31, 2026 application window. If Novo has better positioning in early Medicaid state entries, the oral semaglutide script lead could widen through a channel that the raw TRx data doesn't yet cleanly separate.
The slow Foundayo launch is worth watching, but the coverage architecture question may matter more than launch curve comparisons by the time Q4 data lands.

After a college student finally found a treatment that worked for his ulcerative colitis, UnitedHealthcare decided it wouldn’t pay for the costly drugs.
His fight to get coverage exposed the insurer’s hidden procedures for rejecting claims.
https://t.co/Kyn66KLqmR
Medicare fee-for-service has no equivalent to what UHC's special investigation unit did here (even if it felt brutal to the patient). It just pays.
The gap that never gets named in these stories: commercial payer review workflows are doing two jobs at once. They check medical need and they check whether the provider and the claim are real. When you strip the first function to speed things up, you lose the second one too, because they run on the same pipe.
Medicaid improper payment rates have topped 20% in some years on $700 billion in spending. That math is what happens when prospective review gets thin. The student's story is real and the frustration is valid, but the policy push to gut prior auth in commercial plans is essentially a proposal to trade one visible harm for a much larger, diffuse one that never makes the front page.
Reform that targets speed and automation keeps the fraud filter. Elimination does not. That distinction is getting lost.

.@SenJohnKennedy is spot on — it’s time for hospitals to publish visible, upfront prices so patients can see what they owe before receiving care.
Thank you, @SecKennedy, for working to ensure maximum price transparency in healthcare nationwide!
Visible prices are the easy part. Spent time mapping what actually happens after a hospital posts a machine-readable file: the data sits in a 300MB JSON nobody queries, denominated in chargemaster rates that bear almost no relationship to what any payer actually pays.
The computation layer that matters is 835 ERA claims data, actual paid amount percentiles across payer-plan combinations. That data already exists, it just flows to employers and their TPAs who have every financial reason not to surface it. What's changing is that ERISA fiduciary cases like Lewandowski and Navarro are now treating that 835 data as discoverable evidence, which means employers who ignore available pricing benchmarks are accumulating legal exposure, not just leaving money on the table.
So the policy win here isn't the posting mandate. The posting mandate accidentally built a computable substrate. The question is what enforcement mechanism forces anyone to actually compute against it. Right now that mechanism is plaintiff attorneys in benefits litigation, which is a strange way to operationalize a transparency rule, but it appears to be working.
Price visibility without a pricing computation layer is a press release. The infrastructure question is whether 835 data, MRF data, and AEOB requirements eventually wire together into something a provider or employer can actually execute against at the point of ordering or contracting.

In silico discovery of nanobody binders to a G-protein coupled receptor using AlphaFold-Multimer @NatureComms
1. The study demonstrates a prospective, fully in silico nanobody discovery workflow that finds real GPCR binders: AlphaFold-Multimer (AF-M) screening of 10,000 https://t.co/kYthQiWrbz
GPCRs are one of the hardest classes to crack computationally, which makes a prospective in silico workflow finding real binders genuinely significant. The zero-shot setting matters here, no template scaffolding, no prior binder data as a crutch.
The hit rate question is where this connects to work I've been deep in. Chai-2 achieved 16-20% experimental hit rates in de novo antibody design across 52 diverse targets with no known binders in the Protein Data Bank, a 100-fold improvement over computational methods that typically landed below 0.1%. If AF-M screening of 10,000 nanobody candidates is producing real GPCR binders at comparable or better rates, we're watching multiple platforms independently validate that generative in silico discovery has crossed a threshold, this isn't one lab's anomalous result.
The GPCR context adds a layer that pure hit-rate numbers don't capture. GPCRs are membrane proteins, structurally dynamic, historically resistant to both experimental high-throughput screening and computational modeling, the fact that AF-M can screen candidate nanobodies against them prospectively and recover real binders compresses what used to be years of structure-activity work.
What the field now needs is a direct methodological comparison: AF-M prospective screening versus generative design platforms like Chai-2, not to declare a winner but to understand which approach handles which target class better. GPCRs may favor screening over generation, or the reverse, and that distinction will shape how capital flows into platform development over the next 24 months.

Sat in on an executive MBA class recently. The voiced opinions on AI in healthcare were largely about the need for more regulation in the US. They cited EU policies on AI safety and how AI can make things worse for people without access to resources. Certainly could. But, what
Striking that the access equity frame dominated, because the harder problem isn't coverage gaps, it's whether the AI being deployed is safe enough to cover anyone.
The EU comparison also skips past something. EU AI Act risk tiers assume you can define and bound system behavior at the time of approval. Foundation models break that assumption completely. The model you clear in January isn't the model running in July after a base update or a retrieval index swap. Wrote through exactly this mechanism here: https://www.onhealthcare.tech/p/the-coming-collision-between-foundation?utm_source=x&utm_medium=reply&utm_content=2048130943454416905&utm_campaign=the-coming-collision-between-foundation
Equity matters. But deploying a system that can't be validated to populations with less clinical backup to catch its errors is the worst of both problems.
☀️See you in Rio!
Recursion and our AI research engine, @valence_ai, will be at @ICLR April 23-27 in Rio to share some of our latest breakthroughs in generative modeling for AI drug discovery.
🔹 Check out our poster presentations on:
▪️ TxFM: Effective Biological https://t.co/zD9LSZjyLQ
The timing here is telling. Recursion is presenting generative modeling work at ICLR while still digesting the Exscientia absorption from November 2024, which shed programs and headcount in the process. The academic conference presence signals where they want the platform narrative to land, but the harder question is whether the generative modeling layer connects to the clinical translation infrastructure that actually produces durable differentiation.
That gap between model capability and clinical readout is the central tension I've been tracking across the top-tier AI drug discovery companies. Structure prediction and generative chemistry are now closer to table stakes than moat. The companies that will separate from the field are the ones integrating proprietary perturbational data, automated wet labs, and clinical translation into a single stack, not the ones with the best conference poster.
Recursion has the capital and the phenomics infrastructure to get there. The question after absorbing Exscientia is whether the combined platform produces a clinical signal that validates the whole thesis, because right now Insilico Medicine is the only company in this tier with an actual Phase 2 human readout for a fully AI-discovered, AI-designed molecule. That asymmetry in clinical validation is getting underweighted every time the conversation stays at the model architecture level.

CBO projects Medicare spending goes from roughly $1 trillion a year to more than $2 trillion in seven years.
Washington is still letting fraud drain billions from one of the largest programs in the federal government. https://t.co/yBfNzcpCJt
The June 2023 DOJ Strike Force takedown, $2.5 billion in a single action, gets treated as a win. And it was. But Medicare fee-for-service was already operating at a 6-8% improper payment rate on $450 billion in annual spending before that announcement dropped. The takedown was pay-and-chase working exactly as designed, which is the problem.
When spending doubles to $2 trillion, that improper payment rate doesn't shrink on its own. The structural conditions producing it stay intact: open-network credentialing, no prospective utilization review, a payment model that processes claims before anyone validates whether the provider or the service is legitimate. Commercial plans run fraud losses at 1-3% partly because prior auth and claims review workflows do something Medicare's administrative process doesn't, which is catch bad actors before payment rather than after.
The policy conversation right now is almost entirely focused on stripping prior auth requirements from commercial plans. Nobody is connecting that push to what happens when you remove the one control layer that keeps commercial fraud rates an order of magnitude below Medicare's. You can't dismantle prospective review in the sector where it works and simultaneously complain that the sector without it is hemorrhaging money.
The path forward probably involves AI-driven prior auth automation and predictive fraud analytics built for government payers, not elimination of the controls that are actually functioning.

There is a home health care company in Portland, Maine called ‘Legit Home Healthcare’
Legit Home Healthcare has billed Medicaid $7.1 million
When visiting the building, “They’ve been ‘out for coffee’ for 6 months”
The wife of Somali-born Democrat Maine State Rep Yusuf Yusuf is https://t.co/Aqi9PWOzMG
The billing volume relative to what any actual office presence could support is the tell here, and it's a pattern that shows up consistently when you start linking the Medicaid spend data against basic provider existence checks.
What makes this specific case worth watching is the geographic implausibility problem. A building that's functionally vacant for six months can still generate clean-looking claims because home health documentation is almost entirely self-attesting. There's no independent artifact that proves a visit happened unless EVV is actually being enforced, and Maine's EVV implementation has had compliance gaps that create exactly this kind of window.
The FMAP math also explains why state-level investigation moves slowly. Maine's federal matching rate means the state absorbs a relatively small share of every fraudulent dollar, so the budget pressure to act aggressively isn't proportional to the total loss.
The political connection will dominate the coverage, but the structural story is that this billing pattern would be detectable from public data alone, before anyone visits the building. New entity, rapid billing escalation, thin provider footprint verifiable through NPPES and state corporate filings. The visit just confirmed what the numbers already suggested.
Full breakdown of how to build that detection pipeline from free public datasets, and why home health is where this fraud concentrates, is here: https://www.onhealthcare.tech/p/the-data-stack-that-catches-crooks?utm_source=x&utm_medium=reply&utm_content=2048155754570637587&utm_campaign=the-data-stack-that-catches-crooks
Martin Shkreli says drug companies can charge $2.3 million for a cure because you only need it once
“If you have a cure, you can price it higher as if it was gonna be used for a lifetime”
“Zolgensma is $2.3 million. It rewrites the DNA in your genes, fixes you, and you never https://t.co/OhYNsa681S
The lifetime-use comparison actually obscures a more disruptive problem than price level itself.
Even accepting the logic on its own terms, the $2.3 million number lands as a single catastrophic claim event inside a payer's annual budget. A regional Blues plan covering 400k lives might absorb that hit fine in isolation. The problem is clustering, where gene therapy approvals are accelerating and the probability of two or three such claims hitting the same plan in the same quarter is no longer negligible. Stop-loss carriers already know they can't model that exposure accurately, so they price in conservative buffers that pass cost back to the plan anyway.
The lifetime-value framing also quietly assumes someone is holding the risk across that lifetime. No payer is. Members move between employers, insurers, and Medicare. The entity absorbing the $2.3 million at time of treatment captures none of the downstream savings that justify the price. That misalignment doesn't make the cure less valuable, it just means the pricing rationale and the risk structure are operating in completely different time horizons.
What the debate keeps missing is that the core problem isn't whether $2.3 million is justified. It's that no existing financial infrastructure was designed to absorb claims of this size and timing unpredictability at scale. Prior auth slows the clock, it doesn't solve the distribution problem.

IMO most of US healthcare would be fixed* if we did a few simple things
1) divorce employers from providing health insurance
2) Use a price setting mechanism that was transparent (government setting prices or price transparency)
3) Everyone in one risk pool (e.g. on the
The employer-insurance link alone doesn't explain why fixing it is so hard. The stickiness comes from what built up around it, which is a set of interlocking regulatory layers where each one was a rational response to the distortion created by the one before it. Certificate of Need laws, for example, persisted in roughly 36 states after the federal government repealed the mandate in 1987, not because states believed in the cost-control theory, but because incumbents had already organized around them. That's not a pricing problem or a risk-pool problem. That's path dependency.
The price transparency piece is where your framing gets complicated by the 340B dynamic. By 2023, covered entity purchases under 340B exceeded $66 billion annually, with disproportionate share hospitals accounting for nearly $52 billion of that. The program started as a narrow safety-net discount mechanism and compounded into a revenue strategy that now shapes hospital acquisition behavior, which shapes what prices are even being set against. Transparent pricing layered on top of that doesn't simplify the system, it just makes the distortion more legible.
The single risk pool argument is probably the strongest of the three, but even that runs into Stark Law territory once you start reorganizing how physicians and facilities relate to each other financially. The strict liability structure, up to $15,000 per violation, froze a lot of arrangements that would have actually supported integrated care delivery before any insurer pool consolidation was even on the table.

It accumulated as a series of fixes to previous fixes, and each layer created constituencies that now defend the status quo whether or not the original rationale still holds.
CMS Administrator Doctor Mehmet Oz, FDA Commissioner Doctor Martin MacQuarrie push faster access to medical devices through new regulatory alignment plan.
Watch OAN on Spectrum and YouTube TV today! https://t.co/vc4H9cgBHE
The framing of "regulatory alignment" is where I'd push back a little. What RAPID actually fixes isn't the regulatory side at all. FDA Breakthrough clearance was already reasonably predictable. The broken piece was the five-year gap between FDA authorization and Medicare coverage determination, which had nothing to do with clinical disagreement and everything to do with two agencies running on completely independent administrative clocks.
That synchronization failure is what made FDA approval commercially inert for investors and drove adoption hesitancy among hospitals that couldn't count on payer coverage materializing in any predictable window.
RAPID's mechanism is clock synchronization: FDA authorization triggers CMS proposed NCD issuance on the same day, collapsing what was historically a multi-year reimbursement lag into a 60-90 day finalization window (which is the actual capital markets event here, not the clearance itself). That's a structural fix to administrative sequencing, not a clinical or regulatory reform.
The scope constraints matter too. Roughly 40 devices currently qualify, with around 20 more potentially eligible, and the eligibility bar requires an active IDE study enrolling Medicare beneficiaries with jointly agreed clinical endpoints. With over 1,246 FDA Breakthrough Device designations issued through end of 2025, most of that upstream pipeline doesn't convert to RAPID eligibility automatically.

What if a clinician could see a patient’s prescription costs in real time while prescribing? That kind of transparency helps support better decisions, lower-cost options, and more affordable care. #HealthIT #PatientAccess #Transparency #PriceTransparency @mcuban https://t.co/Tmg0pFrg6Z
Real-time benefit checks already exist in platforms like DoseSpot, and they do surface formulary tiers and out-of-pocket estimates at the point of prescribing. But the gap I kept running into when mapping this space is that those checks are static queries against a benefits database, not dynamic intelligence. The system tells you what something costs, not whether a different molecule, dose, or timing window would achieve the same outcome at lower cost for this specific patient given their metabolic profile.
That distinction matters more than the industry acknowledges.
What I analyzed in looking at incumbents like Surescripts and RXNT is that their architectures were built around transaction processing and compliance, not inference. Plugging real-time pricing into that stack is useful, but it's still a lookup, not a recommendation. And the pharmacogenomic layer, the part that could tell you this patient metabolizes CYP2D6 substrates poorly so the cheaper generic will either fail or cause toxicity, is completely absent from every major platform right now.
The transparency framing is the right instinct. But real transparency at the prescribing moment means integrating cost against predicted efficacy against individual drug response, not just displaying a price tag. Reinforcement learning algorithms that update dosing and drug selection based on observed patient outcomes could operationalize that in ways no legacy e-prescribing stack is architected to support.
The entrepreneurs building on cloud-native infrastructure have a real opening here precisely because the incumbents cannot retrofit this without rebuilding from the foundation up.

important to remember two things - 1) alphafold was built on decades of painstakingly collected xray crystallography, nmr, cryoEM data and 2) protein folding is *NOT* solved, alphafold still under-performs for non-canonical protein types that are important for therapeutic
The point about data quality upstream of the model is exactly what I've been tracing in medical multimodal AI. When I looked at why Lingshu-7B has 5.5x the downloads of the next most-downloaded medical AI model, the answer wasn't architectural at all. It came down to what they did before training: 5.05 million samples curated across 12 modalities, with a five-stage caption synthesis pipeline using doctor-elicited domain preferences to classify and validate each image type. The painstaking collection work you're describing for AlphaFold is the same constraint operating in medical imaging, and teams that skip it pay for it in generalization failures downstream.
The "solved" framing problem you're pointing to has a direct analog in medical AI benchmarks. Models that look complete on standard evaluations frequently collapse on the specific modality where training data was sparse or poorly labeled. Lingshu's own ablation found that medical text data (only 173k samples, the smallest category in their whole training set) caused performance drops across 5 of 7 tasks when removed. Knowledge completeness at the edges matters more than aggregate dataset size.
What doesn't transfer across domains is also telling. Lingshu tried reinforcement learning using Group Relative Policy Optimization (the same approach that works well for math and code) and it failed specifically because medical correctness is knowledge-dependent, not mechanically verifiable. You can check a proof. You can't automatically verify whether a differential diagnosis is contextually appropriate for a given patient presentation. AlphaFold's non-canonical protein problem is structurally similar: the edge cases are the ones where learned patterns from well-represented training distributions stop being reliable.
The production implication is that "solved" in any biomedical AI context should probably mean "solved for the well-represented distribution," full stop.

The whole “AI will cure all diseases” take is still missing the point.
The bottleneck was never ideas.
Did you know every Pharma company has ideas?
Lots of them in my experience
It wasn’t validating those ideas either really.
Companies have highly systematized and
The bottleneck was never ideation or early systematization, agreed. But the framing still stops one step too early.
Clinical validation is where the real compression failure is happening. AI has flooded preclinical pipelines with candidates while clinical success rates have only recently started recovering after decades of decline. The throughput problem upstream made the downstream problem worse, not better.
And within clinical validation, the constraint is even more specific than most people name it. The infrastructure for generating regulatory-grade causal evidence, comparator arms built to FDA's 2025 external control specifications, phenotype normalization across sites, endpoints that map cleanly to real-world populations, basically none of that has been built at scale. The FDA guidance exists. The engineering solution largely does not yet.
One in five real-world oncology patients would not even qualify for the phase 3 trials whose results are supposed to govern their treatment. That gap is the bottleneck. Recruitment tools and trial operations software are not going to close it.

we are literally living in the future and it's not hard to tell:
- OpenAI just launched GPT-Rosalind. a frontier reasoning model built specifically for drug discovery and biology. Amgen, Moderna, and Novo Nordisk are already using it
- Anthropic acquired Coefficient Bio for
The free preview pricing is doing more damage than the model itself, and that part keeps getting buried under the capability story.
The benchmark numbers are also doing a lot of work here. OpenAI self-reported a 0.751 pass rate on BixBench and outperformance on LABBench2 tasks, but they had training-time knowledge of those evals. That's not a minor caveat, it's a validity problem that changes how much weight any of this deserves.
And the launch partner list you'd want to scrutinize is Amgen, Moderna, Thermo Fisher, the Allen Institute, Los Alamos. Novo Nordisk isn't actually on it. Worth double-checking before that becomes the canonical version of the story.
The structural issue I'd push on is that the Codex Life Sciences plugin connecting to 50+ scientific databases is where the real commercial leverage sits, not the model weights. Any biotech AI startup that's been selling essentially a wrapper over public databases, PubMed RAG, lit-review copilots, protocol design tools without proprietary lab data, is now competing against something OpenAI is giving away free to qualified enterprise pharma buyers during a 6 to 12 month preview window. That's not a competitive disadvantage, it's a willingness-to-pay reset across the entire category. I wrote through this in some detail if it's useful context.

Totally agree that AlphaFold didn't “solve” protein folding!
A system that accurately predicts final structures hasn't explained why those residues fold that way, eg., the energy landscape, the kinetic pathways, what happens co-translationally before the chain is even released
The harder version of this problem shows up in complex prediction too. When a monomeric protein scores pLDDT of 50 but its homodimer hits 86, what you're seeing is a folding event that only makes sense in the context of the partner chain. The monomer prediction wasn't wrong exactly, it was asking the wrong question.
Which raises something I haven't fully worked out: if the folding pathway is co-translational and context-dependent, are high-confidence complex predictions telling us about a stable end state, or are they accidentally capturing something about the assembly process itself? The structure looks right, the confidence is real, but the mechanism producing it in the cell may be nothing like what the model computed.
Only 7% of homodimer predictions pass high-confidence filters even with precision at 0.859. The model is selective, but we don't know if what it's selecting for is biological relevance or just structural compatibility.
That gap between predicting the structure and explaining the fold is exactly where I'd push back on coverage that frames AlphaFold's complex expansion as a solved problem. The prediction layer is being commoditized fast, the interpretation layer is not.

Started with standard ChatGPT for clinicians asking for a differential for a GI bleed patient. Then I went into agent mode to have it put together a one pager for the family explaining everything.
Of course, this is not a real patient. https://t.co/PEUeCqizT1
The family summary step is where the architecture question gets real. Generating a differential is a single-turn retrieval problem. Generating a coherent, accurate, appropriately scoped family summary from that differential is a multi-step synthesis problem, and those are not the same thing operationally.
What the Claude Code patterns I analyzed show is that the failure mode in that second step is not hallucination in the classic sense. The risk is contradiction accumulation across reasoning steps, where the agent pulls from different parts of its context and produces a summary that is internally inconsistent in ways a non-clinician family member cannot catch. That is precisely why naive context accumulation without contradiction-resolving memory consolidation is an architecture problem, not a prompt problem.
The 90-plus percent alert override rate in hospital systems is not about wrong alerts. It is about alerts that fail to account for what the clinician already knows. A family summary agent has the same failure mode if it cannot track what it has already resolved versus what it is still synthesizing.
The KAIROS-style self-limiting intervention pattern from the codebase is relevant here too. A 15-second blocking budget for proactive interruption is a specific production constraint, not a philosophy. That kind of scoping is what separates a demo that works on a constructed case from a system you would actually trust at 2am on a real admission.
The independent synthesis question is genuinely hard, and the architecture determines whether it is hard in a manageable way or hard in a hidden way.
More on what the leaked codebase reveals about building this correctly: https://www.onhealthcare.tech/p/what-the-leaked-claude-code-codebase?utm_source=x&utm_medium=reply&utm_content=2048118481405526185&utm_campaign=what-the-leaked-claude-code-codebase
Yes -- It's called "Buy and Bill", where the oncologist purchases the chemotherapy agent from the pharmaceutical company and then resells it to the patient and bills the insurance company. This falls under the Medicare "chemotherapy concession", resulting in 80-90% profit margins
The buy-and-bill margin figure is real, but 80-90% overstates what most community oncology practices actually pocket after accounting for drug acquisition cost, wastage, cold chain handling, and nursing administration overhead. The margin on the drug spread itself can hit those numbers in specific cases (think high-cost infused agents with significant ASP-to-acquisition gaps), but the blended practice economics are considerably messier.
What I'd push back on more directly: framing this as purely regulatory arbitrage undersells how intentionally the reimbursement structure was designed. CMS built the ASP-plus-6% add-on specifically to keep infusion viable in community settings after the 2003 MMA reforms gutted AWP-based payments. The dysfunction is real, but it has a policy rationale, even if that rationale has been captured by incumbent economics over time.
The deeper structural problem I've been tracking is what happens when a $2 million CAR-T case hits that same buy-and-bill infrastructure. Community oncology practices cannot carry that inventory risk. Aradigm (which came out of stealth backed by Andreessen and Frist Cressey in December 2024) is essentially building cost-plus financing rails specifically because the buy-and-bill model breaks completely at cell and gene therapy price points. The margin extraction you're describing in conventional chemo is exactly what makes the alternative payment model problem so urgent one layer up the cost curve. (The irony is that fixing CAR-T financing probably accelerates scrutiny of the traditional infused drug spread too.)

A patient with stage four cancer doesn't have the luxury of waiting for the evidence timeline to close. A regulator doesn't have the luxury of approving therapies that haven't been proven. Both positions are correct in isolation. The problem is that the system was never designed https://t.co/RfD55rsHZy
The tension you're naming is real, but the usual framing stops too early. Both positions being "correct in isolation" implies the gap is primarily ethical or philosophical, a values conflict between speed and rigor. What I found when I looked at this closely is that it's mostly an engineering gap being mistaken for a values gap.
The FDA's 2025 draft guidance on externally controlled trials doesn't say no. It issues specific technical conditions: phenotype normalization, covariate alignment, endpoint mapping. That's a spec sheet, not a door closing. The problem is nobody has fully built what that spec describes, so the conflict looks irresolvable when it's actually just unbuilt.
The TrialTranslator data sharpens this in an uncomfortable direction. Real-world oncology patients survive roughly six months less than trial populations, and about one in five wouldn't even qualify for the phase 3 that generated the approval. So the evidence we're debating the timeline of is already producing a distorted signal for the patients most desperate for it. The urgency argument and the rigor argument are both weakened by that finding, just in different ways.
Which raises the question I keep coming back to: if the comparator infrastructure existed to actually measure where a therapy's effect attenuates across real populations, would regulators need to be as conservative on initial approval, or does that just relocate the same standoff downstream?

Repertoire-scale antibody structural prediction informs therapeutic design
1 AF3-TurboAb is presented as a practical way to run antibody–antigen complex structure prediction at repertoire scale: ~0.5 min per seed on a single GPU while keeping near-experimental interface https://t.co/IWSL9nqwsk
The throughput angle here is underappreciated. Prediction speed at repertoire scale changes what questions you can even ask, because the bottleneck shifts from computation to experimental validation capacity.
But what happens when generation outpaces validation? That's the structural tension I kept returning to when looking at Chai-2's numbers. 20% experimental hit rates in de novo antibody design (across 52 diverse targets, zero-shot, no known binders in the PDB) sounds like a solved problem until you realize the remaining 80% still needs wet-lab time to discard. Faster structural prediction upstream means more candidates flowing into that same downstream experimental queue.
The real constraint isn't compute anymore. And faster folding tools, however genuinely useful, don't dissolve that bottleneck, they pressurize it.
What changes the economics is generative design reducing the candidate pool before prediction even runs (designing fewer, better candidates rather than filtering large ones). That's the direction Chai is pointing, with the platform described as closer to "Photoshop for proteins" than a screening tool. Repertoire-scale prediction and generative design are solving adjacent problems, but from opposite ends of the same pipeline, and the field needs both moving together for the throughput gains to actually land in clinical timelines.
(The 0.5 min per seed figure is genuinely useful for what it does, the question is what it feeds into.)

Proteins, with their varied structure and chemistry, are the prime actors of biology and have long been targets for in vitro and in silico engineering. Generative protein models and other artificial intelligence tools are now being integrated into experimental workflows.
In a https://t.co/4IlIWhsQuS
The part that gets underweighted in most coverage of generative protein models is what happens after the design step. RFdiffusion hitting 80+ percent experimental validation rates for designed protein-protein interactions (published Nature 2023, Baker lab) is genuinely striking, but validation of a single target interaction is a different problem than making that protein useful as a medicine.
The commercial bottleneck is multi-objective: a protein that binds its target with high affinity can still fail on immunogenicity, half-life, manufacturability, or tissue distribution, and current foundation models are largely optimized along one axis at a time. The design-to-clinic gap isn't being closed by better generative models alone. It closes when those models are embedded in closed-loop systems that feed experimental assay data back continuously across all those dimensions simultaneously (which is where the real infrastructure build is happening right now, quietly).
There's also a substrate question the integration narrative skips. Generative models expand what's designable, but the delivery and genetic modification layer determines what's actually deployable in a patient. PASTE systems now achieving 20-50 percent efficiency for kilobase insertions in human cells changes the calculus on which designed proteins can actually be encoded and expressed in vivo at therapeutic scale. The designed protein and the system that gets it into the right cell are co-constraints, and optimizing them independently is what keeps timelines long.

Every time I tell AI utopianists that biology is too complex for AI to "solve", they cite the success of AlphaFold.
No, AlphaFold did not "solve" protein folding. It gets broad structures correct ~70-88% of the time (depending on evaluation), enabling useful but flawed
The AlphaFold-solved-folding take collapses pretty fast when you look at the actual numbers from large-scale deployment.
When you run 31 million complex predictions through a calibrated filter, roughly 7% of homodimers pass high-confidence thresholds. The pipeline gets 75% of predictions to a usable quality floor. That is genuinely useful, but it is a long way from solved, and the heterodimer problem is worse: 57,000 tentatively high-confidence heterodimers out of millions of candidates, drawn from a set already biased toward well-annotated physical interactions in STRING. The hardest drug targets, the transient complexes, the weak-affinity pairs, the ones biology actually uses for signaling, are almost certainly underrepresented in that 57K.
What I keep finding is that the "AI solved X" framing collapses on the confidence side every time. The prediction layer is getting commoditized fast, NVIDIA and DeepMind are releasing both the structures and the inference tools freely, but the gap between a predicted structure and a structure you can trust enough to act on is where the real work is. That gap is not closing at the same rate as raw prediction volume.

The "months to hours" framing is real, but the architecture question matters more than the timeline. When I dug into the leaked Claude Code source, the thing that stood out wasn't the speed gain, it's that the 46,000-line query engine has active contradiction resolution baked in, not naive context accumulation. Stack that against prior auth workflows where a single case spans payer criteria, EHR notes, and submission history simultaneously, and you see why the memory architecture is the actual moat, not the orchestration layer everyone's focused on.
Autopilot only holds if the memory doesn't drift.

A researcher gave an AI agent access to his shell, his files, and his network. Then he proved that every safety guardrail we trust is architecturally useless.
It cannot tell the difference between your instructions and a hacker's.
The paper is called Parallax: Why AI Agents https://t.co/oFL52VA89W
This is the right framing and it's why the "we fine-tuned for safety" answer keeps failing in production environments.
The structural problem is that in-process guardrails, whether system prompts, behavioral instructions, or internal classifiers, exist inside the same process space they're supposed to constrain. A compromised agent with persistent shell access can't be expected to self-police against instructions it can't distinguish from yours. That's not a model quality problem, it's an architecture problem.
What changes the equation is enforcement that lives outside the agent process entirely. I went deep on exactly this when I looked at NVIDIA's NemoClaw stack and how it handles clinical environments where an agent is sitting on live EHR credentials. With 167 million individuals affected by health data breaches in 2024 alone, the stakes for getting this wrong in healthcare are not abstract.

✂️ CRISPR is a revolutionary gene-editing tool — but active enzymes can linger in cells and cause dangerous off-target damage.
Anti-CRISPRs are the fix. But in a decade of research, only 118 have ever been found in nature.
AI just changed the game:
🤖 RFdiffusion designed https://t.co/xXeKSmy07o
The scarcity problem you're describing is exactly what I tracked when writing about RFdiffusion's experimental validation rates. Baker lab's system hit over 80 percent success on designed protein-protein interactions, which means the bottleneck was never our ability to validate candidates, it was our ability to generate enough of them in the first place.
118 natural anti-CRISPRs found over a decade, that's the ceiling biology gave us. AI removes the ceiling entirely.
What the therapeutic community is still working through (and this matters for the safety framing here) is that anti-CRISPR design isn't a standalone win. The real unlock is pairing controllable off-switches with large-insert delivery systems. I wrote about PASTE achieving 20 to 50 percent efficiency for kilobase insertions in human cells, and the honest constraint is that scalable in vivo editing only becomes clinically responsible when you can modulate the editing machinery after delivery. Designed anti-CRISPRs give you that dial.
So what you're calling a safety story, I'd frame as the enabling layer for the whole next generation of in vivo genetic medicine. You can't confidently deploy persistent editors at clinical scale without a reliable off-switch, and natural protein discovery was never going to generate enough structural diversity to cover every therapeutic context.
The convergence here is the point. Diffusion-based protein design plus large-insert editing plus programmable inhibition is where entirely new therapeutic logic becomes possible, not incremental dose optimization.

Gotta make charge masters real prices or get rid of them. The CM is like WAC in pharma. It's a made up number that abuses the uninsured , those in their deductible phase, and those who need a drug or care that isn't covered
The only reason both exist is so OBMs and the
Chargemasters and WAC share the same original sin: they were never meant to be patient-facing prices.
WAC was designed as a starting point for manufacturer-to-wholesaler negotiation. Somewhere along the way it became the benchmark that determines how much a patient pays during the deductible phase, before rebates have cleared the system. The $1,000 list price with a $400 rebate baked in means the patient settling their deductible pays against $1,000. The plan settles later for $600. The patient never sees that correction.
The chargemaster does the same structural work for hospital billing. It exists to anchor negotiation with large payers, and the uninsured patient gets handed that anchor price directly because there's no contracted rate to fall back on.
What makes both durable is that the intermediaries who benefit from opacity, PBMs on the drug side, insurers and large health systems on the facility side, have strong incentives to prevent any standardized disclosure regime from emerging. Surgical reforms that target WAC or chargemaster pricing in isolation keep running into this. You fix the number but leave the enforcement infrastructure empty, and the spread migrates somewhere less visible.
The deductible phase is where the WAC abuse concentrates most visibly. I've been pulling on that thread, and the downstream picture is messier than most proposals account for.

Uncomfortable truth: most telehealth practices offering GLP-1s use them as a lead-generation tool to acquire patients.
Their teams often lack the expertise to properly evaluate and manage obesity or deliver comprehensive, evidence-based care.
Access alone isn’t the issue. It’s
The acquisition funnel problem is real, but the infrastructure story underneath it is messier than the expertise framing suggests.
When UnitedHealthcare built Total Weight Support, they made Real Appeal Rx or WeightWatchers participation a hard coverage gate, not a recommendation. That design choice wasn't about clinical quality, it was about shifting discontinuation risk off the payer's books. The 1-in-12 patient persistence rate at three years and 60% weight regain within 12 months of stopping are what's actually driving that gate, and employers are watching the same numbers with growing alarm.
The telehealth GLP-1 platforms you're describing aren't just under-resourced clinically. They're structurally misaligned with what payers and large employers are now requiring as conditions of access. Lilly's Employer Connect launched March 2026 with 15+ program administrators including Form Health, Calibrate, and 9amHealth, and Novo has a parallel direct-to-employer channel through Waltz Health. Those deals aren't being built on the "we write prescriptions fast" model you're critiquing. They're being built on adherence management, outcomes documentation, and indication-specific care pathways.
The access-only platforms will get squeezed from both directions: payers building behavioral gates and manufacturers building direct employer relationships that require clinical infrastructure the lead-gen telehealth model was never designed to provide.

Expanding HSAs would give people more control over healthcare choices. However, it puts IRS bureaucrats in charge of deciding what is “healthcare” and would likely spur rather than reduce US healthcare inflation by encouraging more dollars to go into healthcare expenses. HSAs
The IRS ambiguity problem is already live, not theoretical. There is no clear IRS ruling on whether DPC subscription fees count as a qualified medical expense (the fee covers access, not a specific medical act, which is where the agency gets stuck). So every dollar routed into an HSA for primary care sits in a gray zone that the IRS has not resolved.
On inflation: the mechanism worth watching is what happens when you redirect subsidy dollars that currently suppress premiums into open-ended spending accounts. ACA enrollees at 200-400% of the poverty line already face silver plan deductibles of $3,000 to $8,000 on top of sub-$100 monthly premiums. If HSA expansion pulls dollars away from premium support without fixing the deductible structure, you get the same access problem with an added layer of tax-code complexity and no price signal to slow spending.
The control argument also runs into supply. DPC practices currently serve roughly 1.5 to 2 million patients out of 330 million Americans. Consumer choice only works when there is something to choose from, and in rural markets there often is not.

That's a real complication for the behavioral gate model I wrote about at https://www.onhealthcare.tech/p/how-commercial-insurers-self-insured?utm_source=x&utm_medium=reply&utm_content=2048041479399158041&utm_campaign=how-commercial-insurers-self-insured, because 34% of covering employers already require lifestyle program participation as a coverage condition, and none of that access infrastructure is built to screen for or respond to restrictive eating risk. You're essentially mandating behavioral compliance from a population you haven't screened, which is a liability the utilization management layer wasn't designed for.
India’s weight-loss drug market just ran a live experiment in price elasticity.
Novo Nordisk’s semaglutide patent expired 20 March 2026.
Within 3 weeks:
15+ generics launched
Cheapest at Rs 2,000/month (branded was Rs 10,000+)
Novo cut Ozempic and Wegovy prices by 36-48%
But here is the part nobody saw coming.
🧵
Generic entry forcing a 36-48% price cut in three weeks is a clean data point, but the US trajectory won't follow this cleanly whenever Ozempic's patents fall.
The Indian market didn't have a behavioral gate infrastructure sitting on top of access. No employer requiring dietitian enrollment as a coverage condition, no PBM with a utilization management layer tied to indication-specific rules, no outcomes-based contracting rails that need to reprice when the underlying drug cost moves.
In the US employer market right now, only 1-in-12 patients is still on GLP-1 therapy after three years. That discontinuation rate means the access infrastructure problem doesn't get solved by cheaper drugs. It might actually get harder, because lower prices will expand the eligible population faster than employers can build the operating model to manage it.
What I keep coming back to: Lilly's direct-to-employer channel at $449/dose is already undercutting the PBM rebate math, and that's before any generic pressure. So the question isn't whether price competition arrives in the US, it's whether PBMs still control the access layer when it does, or whether that value has migrated elsewhere by then.

When a $100 genome produces a VUS in a gene nobody has studied deeply, you're not just waiting for more population data. You're waiting for someone to understand what the model of that gene's function is even supposed to look like. That's where I keep landing when I think about what's changed in the stack: the bottleneck moved from data generation to explanation, and the tools we have for closing that gap are still mostly statistical rather than mechanistic.
What caught my attention in work I've been doing on mechanistic interpretability applied to genomic models is that foundation models trained on biological sequences appear to encode variant-level knowledge that hasn't been formally described anywhere. The Goodfire/Arc Institute work decoding Evo 2 and publishing it in Nature is a concrete example of a model being reverse-engineered to surface what it learned, rather than just what it predicted. That's a different kind of knowledge transfer than anything a GWAS or even a clinical variant database gives you.
Your point about indefinite interpretive evolution is exactly right. The question I'd add is whether interpretability tooling can accelerate that cycle, pulling forward the moment when a VUS becomes a diagnosis by surfacing what the model already knows about mechanism.

Since I began work on AI in 2010, training compute for frontier models has grown by one trillion times.
Now we're looking at something like another thousand-fold growth in effective compute by the end of 2028.
1000x the existing 1,000,000,000,000x.
Extraordinary stuff.
The compute curve is wild, but the health tech world is still pricing AI products like we're in 2023. Companies selling clinical AI on current AWS inference costs are going to look very different in 36 months, the unit economics that make a genomic variant pipeline marginal today flip completely when you drop inference cost by an order of magnitude.
The part nobody in health tech wants to sit with is that compute access stops being a moat. The defensible companies are the ones with proprietary clinical data and deep workflow lock-in (everything else is renting an advantage that's about to get commoditized).
Wrote about this specifically in the context of Musk's Terrafab announcement, because I think health tech is sleeping on what a 50x supply expansion does to the economics of deploying real-time clinical decision support at population scale: https://www.onhealthcare.tech/p/the-elon-terrawatt-announcement-nobody?utm_source=x&utm_medium=reply&utm_content=2046989133676257284&utm_campaign=the-elon-terrawatt-announcement-nobody
A new article introduces EchoNext-Mini, an open dataset of 100,000 electrocardiograms with curated structural heart disease labels and an accompanying convolutional neural network model for detecting structural heart disease from electrocardiogram data. https://t.co/mMudlPtJkl https://t.co/nccVaBuTCm
Datasets like this are doing real work, but the adoption question is almost always downstream of the label curation methodology, not the model.
What I found looking at Lingshu-7B's download dominance over every other medical AI model is that developers aren't picking winners on benchmark scores. They're picking on how much evaluation overhead a model removes from their workflow. A standardized 100k ECG dataset with clean structural labels is genuinely useful, but whether it gets used at scale probably depends more on whether someone builds reproducible evaluation infrastructure around it than on the CNN performance numbers.
The GRPO failure in Lingshu also points at something relevant here. Cardiac interpretation from ECG is knowledge-driven in exactly the same way, structural findings aren't mechanically verifiable the way a math answer is, so any reinforcement learning layer on top of this dataset is going to run into the same wall.
Curious whether the label curation pipeline here has a validation discard mechanism or whether borderline cases just got included with softer confidence scores, because that tradeoff shapes basically everything downstream.

Attention PK nerds, pharmacologists, and clinicians who actually understand serum levels:
I haven’t seen this discussed, but it could matter for patients priced out of injectables.
If a 25 mg oral semaglutide tablet has ~1% bioavailability, that’s ~0.25 mg systemically… on
The 1% bioavailability figure is real, but the clinical story gets more complicated fast. Oral semaglutide's absorption is highly variable, food and water intake dependent, and the exposure curve looks nothing like the subcutaneous profile even when the math suggests equivalence. That variability is partly why the PIONEER trials required fasting administration with specific water volume, and it's why dose titration for oral formulations carries different risk than for injectables.
The deeper issue I raised in my piece on the peptide economy is that bioavailability constraints may actually accelerate the cost access problem rather than solve it. If 1% absorption means you need 25mg oral to approximate 0.25mg systemic, and higher oral doses are required to hit clinical targets, the manufacturing cost per therapeutic unit goes up even as the delivery mechanism looks cheaper on the surface. The molecule commoditizes eventually, but the formulation technology sitting around it, absorption enhancers, delivery matrices, dosing protocols, is where the durable margin concentrates. Which raises a question for the access framing: cheaper delivery mechanism does not automatically mean cheaper per-unit therapeutic exposure, so who captures the formulation premium and does it get passed to the patient or absorbed upstream?
What I haven't seen modeled well is whether oral titration protocols can be standardized enough for primary care to manage without specialist support, because that's where the real access unlock would sit.

A 65% cholesterol reduction has been available since 2015. Almost nobody could get it. The drug required a needle every two weeks, cost $5,850+/year, and insurers fought every prescription.
@Merck spent a decade figuring out how to put the same mechanism in a pill. Enlicitide:
What does it say about the access system that the solution to a decade of prior auth obstruction is reformulation, not reform?
Because that's the question this pattern raises for me. The mechanism worked. The clinical evidence was there from 2015. What wasn't there was a benefit design infrastructure willing to process it, and payers used every available friction point, injection burden included, to hold utilization down.
I've been watching the same logic play out in GLP-1 coverage right now, where the fight over access has very little to do with whether the drugs work and everything to do with how the operational layer around eligibility gets built. I wrote about it here https://www.onhealthcare.tech/p/how-commercial-insurers-self-insured?utm_source=x&utm_medium=reply&utm_content=2048074556271985094&utm_campaign=how-commercial-insurers-self-insured when looking at how employers are layering behavioral gates, indication-specific rules, and outcomes contracting on top of GLP-1 formulary decisions because the traditional prior auth model genuinely cannot handle the complexity.
The PCSK9 story is a clean example of what happens when access infrastructure is never built: utilization stays suppressed, the ROI case never gets made, and manufacturers eventually have to absorb the reformulation cost to get around the friction. That's not the payer system working, it's manufacturers paying to route around a broken gate. The question for enlicitide is whether the pill form actually changes the prior auth calculus or just removes one of the stated objections while the underlying denial logic stays intact.
On the Hill this week, we heard how insurers are standing between patients and care.
New data shows 70% of patients are initially denied coverage for a prescribed medicine, delaying or preventing treatment.
Patients should not face red tape. It is time to put them first. https://t.co/zVlkOVE5xn
Denied on the first pass has been the default state for years, and the real question this data raises is whether digitization actually fixes that or just makes the denial faster.
What I keep coming back to: the 70% figure tells you about outcomes, but Conway's Law tells you why the number is sticky. Payer utilization management org charts are built around fax-and-phone workflows, and those org charts produce the system they're organized to produce. CAQH data puts electronic prior auth at only 35% of transactions today. When 9% of organizations still can't support ePA APIs by 2027, you're not automating a process, you're automating the edges of a process while the center stays intact.
The place this gets harder than the advocacy framing suggests: real-time approval rates only improve if the submission is complete. AHIP and BCBSA commitments target 80% real-time approval of complete submissions, and "complete" is doing enormous work in that sentence. The criteria for completeness are still set by the payer.
So the 70% denial rate probably doesn't fall just because the channel shifts from fax to FHIR. The question is whether state SLA laws, which are starting to convert utilization management into an accountable service-level-agreement business, create enough external pressure to move the underlying decision logic, or whether payers just route faster to the same answer.

🚨🇺🇸 | Tras su decreto “Most Favored Nation”, Trump logró que las 17 compañías farmacéuticas más grandes del mundo, que representan el 80% del mercado, acuerden vender sus medicamentos en Estados Unidos al precio más bajo del mundo, tras décadas de mega sobreprecios contra los estadounidenses.
The 80% market coverage figure is the one that needs pressure applied to it, because it's measuring branded drug revenue share, not prescription volume. Branded drugs are a fraction of total scripts filled in the US, generic volume dwarfs them, so the 86% branded market figure the White House is using translates to something considerably smaller when you denominate it against actual utilization.
The piece that's getting lost in the headline framing is that these deals are bilateral and confidential. No published reference country basket, no MFN formula, no drug-by-drug pricing schedule that any third party can audit. The 17-company cohort itself has to be reconstructed from fragmented sources across months of press releases and AJMC reporting, there's no single government document you can pull that lists and confirms the full cohort.
And the GLP-1 pricing, the $245 Medicare/Medicaid number for Ozempic and Wegovy, creates a problem that goes well past affordability optics. That public benchmark price is now visible to every ERISA plan fiduciary in the country, and when commercial plans are paying more through PBM-intermediated channels, the question of whether plan sponsors breached their fiduciary duty becomes a litigation question, not a rhetorical one.
TrumpRx as currently built can't close that gap, it's a cash-price browse page without eligibility verification, prescriber workflow integration, or secondary payer coordination.

Kensho AI Mafia led by @DanielNadler needs to be studied. Particularly their success in Vertical AI. From a cursory look, Kensho alumni have founded:
- Suno (music)
- OpenEvidence (healthcare)
- Chai Discovery (biopharma)
- LangChain (agent infra)
The Chai Discovery one is worth sitting with for a second (because the others on that list are impressive but mostly in the "great product" category). Chai-2 hit 16-20% wet-lab success rates in zero-shot antibody design across 52 novel targets. Prior compute methods were under 0.1%. That gap is not a product story, it's closer to a physics story.
The alumni angle is real but I'd push on what Kensho actually trained people to do. My read is it was less about AI and more about what happens when you force domain experts and ML people into the same room with actual stakes on the line. Biopharma is the place where that combination either proves out or blows up.
The question I keep coming back to: does the Kensho origin matter once these companies need to operate at scale, or does it only explain the founding insight and then the clock resets?
More on the Chai side here: https://www.onhealthcare.tech/p/the-chai-discovery-inflection-how?utm_source=x&utm_medium=reply&utm_content=2047040184165007694&utm_campaign=the-chai-discovery-inflection-how
While nearly 18% of U.S. adults have taken a GLP-1 drug for weight loss or to treat a chronic condition, about half of people will stop taking it within a year. Often, they don’t understand what is likely to come next. 🔗: https://t.co/4k6wr8fjCf https://t.co/NGHc3JzOJ3
Stopping is the part nobody prices in.
Two-thirds of weight lost on semaglutide comes back within a year of discontinuation. Patients aren't told that upfront, and payers aren't modeling it until the spend hits. But the deeper problem is that the discontinuation rate itself is being treated as a patient behavior issue when it's really a care delivery failure: no structured side effect management, no dose titration support, no coverage continuity.
I ran the math on what that 50% dropout rate costs a 100,000-member commercial plan. It's around 4.7 million dollars in wasted annual spend, and that's before you factor in the downstream utilization when conditions go unmanaged.
The clinical trial efficacy numbers are real. The real-world adherence numbers are not. Only 27% of GLP-1 patients hit adequate adherence by proportion of days covered, which means the gap between what these drugs can do and what they're actually doing in practice is enormous, and measurable.
Full breakdown of where the investable opportunity actually sits: https://www.onhealthcare.tech/p/the-glp-1-gold-rush-where-smart-money?utm_source=x&utm_medium=reply&utm_content=2047982843825987777&utm_campaign=the-glp-1-gold-rush-where-smart-money
Over half of the web content is now generated by AI. What does the future hold for electronic health records as AI applications permeate clinical workflows?
In our recent article @npjDigitalMed, we take a deep dive into this question with real-world examples.
🧵👇 https://t.co/nfQb0QMWcv
The EHR question is real, but the AI scribing piece of it is where I'd push back on the optimism a bit. Pilot data looks clean until you zoom in on medication transcription, where word error rates across systems ran 35% to 86% in the studies I've been analyzing, and Google and Amazon's models hit above 94% error rates on clinically relevant non-lexical sounds. That's not a maturation problem you iterate through quietly, that's a liability surface that grows with adoption.
The deeper structural issue your framing might be underweighting: EHR vendors like Epic aren't passive recipients of AI applications permeating their workflows. They're building native documentation features that will commoditize the standalone scribe layer entirely. So the question of what AI does to EHRs is partly a question of whether EHRs absorb AI or get disrupted by it, and right now Epic's 30% US hospital market share suggests absorption is the more likely trajectory for ambient documentation specifically.
The "real-world examples" framing matters too. Most published validation work on AI scribes used simulated consultations, seven of nine studies in one systematic review I drew from were US-based with largely homogeneous English-speaking populations. The gap between that controlled evidence base and actual diverse clinical deployment is where the interesting failures will happen, not in the demos.

Follow the bottleneck.
Chips → data centers → grid equipment → power → gas turbines
Grid equipment grew 1%/yr for decades. Then data centers showed up as an entirely new buyer.
Gas turbine makers shipped 5–7 GW/yr. Last year? Orders hit 100 GW.
@maxlbcook on how he https://t.co/J3XzjhrN2h
Ran into this exact dynamic when modeling inference cost curves for clinical AI deployment. The binding constraint on scaling real-time decision support to population level isn't FDA clearance or EHR integration. It's power and the chips that consume it.
The gas turbine bottleneck you're describing is the part most health tech operators aren't tracking (and it matters enormously for how quickly inference costs actually fall). A 50x increase in compute output means nothing if the power infrastructure to run it takes a decade to build. The Terrafab announcement gets treated as a chip story, but it's also a grid story.
And health systems making major capital commitments to on-premise AI infrastructure right now are essentially betting on where that bottleneck resolves and when. Get that wrong and you're looking at stranded assets on the same timeline as the 2010-2018 cloud migration, except faster.
But the deeper issue for health tech investors is that compute commoditizing changes which moats actually hold. Companies whose defensibility rests on superior compute access rather than proprietary clinical data or regulatory clearances are going to feel this first, well before the turbine orders translate into cheaper inference on AWS.

‘I knew I wanted to to do emergency medicine, but becoming a doctor would have taken a decade of my life’.
Doctors have been shafted globally - instead of reforms to the profession, they introduced low-quality alternatives and kept doctors as shock absorbers.
Immoral. https://t.co/dgPjI0PJLD
The question this raises: if we agree doctors were "shafted," which doctors, exactly, and by how much?
Because the compensation story is more fractured than it appears. My actuarial work puts family medicine physicians at 56% below their measurable value contribution, and pediatricians at 72% below, the single largest gap in the entire compensation spectrum. Emergency medicine physicians, the specialty the person quoted walked away from, sit at 119% above their actuarial value target, earning $530,000 against a measured contribution of $242,000.
So the "doctors were shafted" framing is doing a lot of work across a very uneven distribution.
The structural problem is that fee-for-service payment renders chronic disease management and care coordination invisible for reimbursement, which means the physicians doing the most system-level work, bending cost curves, generating quality-adjusted life years through prevention and longitudinal care, are compensated least. Medical students read that signal correctly and rationally flee primary care. The workforce shortage we call a crisis is a direct output of a compensation architecture we chose.
And even that framing leaves something unresolved: if you corrected the education debt structures and residency allocation tomorrow, how long before the labor market actually reflected those changes, given that even Kaiser Permanente can't fully escape the distortions baked into national training pipelines?

U.S. nursing homes are fabricating schizophrenia diagnoses to hide their use of dangerous antipsychotic drugs to subdue dementia patients, a government watchdog report found.
The drugs increase the risk of falls, strokes and death. https://t.co/6SkzWxZfSz
The diagnosis fabrication is the tell, not the drug use itself, because it means facilities already know the use is indefensible and are building paper cover before the chart ever gets audited.
Which connects directly to the structural problem I found when I dug into the hospice fraud infrastructure: the billing code is always downstream of a clinical judgment call that CMS has almost no real-time visibility into. Whether it's a schizophrenia label applied to a dementia patient who won't sit still, or a terminal prognosis applied to someone who isn't actually dying, the fraud lives in the gap between what a clinician documents and what CMS can verify from claims data alone.
That gap is exactly what CMS is now trying to close in the hospice context through the Subsequent Survey Vulnerability Index, which scores providers on nine claims-based metrics precisely because chart-level documentation has proven nearly impossible to audit at scale. The SSVI is an admission that CMS cannot trust clinical documentation and has to work backward from billing patterns instead.
The schizophrenia diagnosis scheme and the hospice per diem scheme are the same architecture: manufacture a qualifying clinical label, bill against it, and rely on the audit lag to keep the revenue flowing (the lag in nursing homes being survey cycles, in hospice being the cap reconciliation timeline, both measured in years).
The real question neither enforcement regime has answered yet is whether the fraud follows the payment model or whether the payment model was always going to produce the fraud.

Regeneron is the 17th pharmaceutical giant offering to sell their drugs at Most-Favored-Nation drug pricing. 🇺🇸
It's simple: President Trump refuses to let America get ripped off in the global drug market. The United States will have the LOWEST drug prices anywhere in the world. https://t.co/W3Uyh602Ao
The Regeneron deal is real. The 86% branded market coverage claim the White House attached to it is where things get slippery.
Branded drugs are a minority of total prescription volume. That denominator matters enormously when you're making a coverage claim, and no one in the administration's framing is disclosing it.
The harder problem is what happens after the deal is signed. The $245 Medicare/Medicaid price on GLP-1s is now a public benchmark. Every employer plan paying more through a PBM has a visible gap between what their members pay and what the government negotiated. ERISA fiduciary exposure doesn't require a lawsuit to start moving behavior, it just requires the number to be visible. That number is now visible.
And there's still no published contract text, no reference country basket methodology, no MFN calculation formula anyone outside the bilateral parties can audit. TrumpRx lists 80 drugs. That's the only live artifact of actual pricing commitments. The compliance and adjudication infrastructure those deals require hasn't been built.
The pricing cuts are real. The implementation layer is a vacuum.

.@SecKennedy on the “rip-off” that @POTUS has ENDED with Most Favored Nation negotiations:
“He said we’re going to lower [drug prices] this time no matter what.”
➡️ America has 4.2% of world’s population
➡️ Takes 13% of the pharmaceutical drugs
➡️ Pays 80% of the biotechnology research
➡️ Provides 75% of profits to the pharmaceutical companies
The 80% R&D subsidy framing is real and the political grievance behind it is legitimate. But it stops exactly where the analysis gets hard.
The 17 deals don't have published contract text. No reference country basket. No MFN formula. No drug-by-drug pricing schedule anyone outside the bilateral negotiation can verify. What Kennedy is describing as ended is a pricing dynamic whose replacement mechanism hasn't been made legible to the people who would need to implement it: state Medicaid programs, employer plan fiduciaries, PBMs trying to model GLP-1 rebate economics against a $245 public benchmark.
That last piece is where the exposure concentrates. When Medicaid net prices on Ozempic and Wegovy become visible at $245 a month, every self-insured employer paying more through their PBM contract now has a documented spread and an ERISA fiduciary question they cannot ignore. The "rip-off ended" framing actually accelerates that litigation risk rather than resolving it, because it makes the benchmark public without creating any adjudication infrastructure to act on it.
TrumpRx lists 80 drugs. It has no eligibility verification, no prescriber workflow, no real-time benefit comparison. The pricing commitment is real. The plumbing to deliver it isn't built.
The 75% of profits statistic is a negotiating argument. Whether it translates into durable price compression depends entirely on contract mechanics that haven't been published.

🔥 @SecKennedy on negotiating Most Favored Nation agreements — delivering the lowest drug prices in the world for Americans:
“We were paying the highest prices for drugs in the world…Now we’re paying the lowest.”
“We’ve dropped IVF by 83%, we’ve dropped GLPs by 89%, insulin, COPD drugs, asthma drugs.”
“Now the [American people] are paying the lowest cost in the world rather than the highest.”
“[Congress] can do this better than us. We did it because you wouldn’t act.”
“You’ve been promising to do it for 20 years and you’ve never done it.”
The $245/month Medicare/Medicaid price on Ozempic and Wegovy is real. What Kennedy isn't explaining is the mechanism that gets any individual patient to that number, because TrumpRx currently has no eligibility verification, no prescriber workflow integration, and no real-time benefit comparison layer sitting between that published price and an actual adjudicated claim.
The "89% GLP-1 reduction" figure is doing a lot of work here. Reduced from what baseline, through which channel, for which payer type, is the entire question (and none of that is in the deal text, because the deal text isn't public). The Lilly-Novo agreement gives you a Medicare copay cap of $50 and a cash price of $350 through TrumpRx. Those are three different numbers for the same drug depending on which pipe you're standing in. Kennedy is collapsing those into one claim.
The ERISA angle is the piece nobody is picking up. When a public MFN benchmark price becomes visible below what a commercial employer plan is paying their PBM, that's not just a policy curiosity. That's a fiduciary exposure question with litigation attached to it.
The 86% branded market coverage claim the White House is using comes from deal count, not prescription volume. Branded drugs are a minority of total scripts filled.
I reconstructed the full 17-company cohort from fragmented sources because no single government document lists them: https://www.onhealthcare.tech/p/what-does-17-pharma-mfn-deals-are?utm_source=x&utm_medium=reply&utm_content=2046968418658582736&utm_campaign=what-does-17-pharma-mfn-deals-are
The AMA's race-based scholarships are bad enough but even worse because every single one of us were funding it.
This is because the AMA has a monopoly on the CPT coding system. So, every time a doctor places an order in an EMR (labs, imaging, medications, surgery), the AMA gets
The CPT revenue piece is real, but the monopoly framing needs some friction. The AMA holds copyright over CPT, yes, and licenses it to EHR vendors who pass those costs to providers. But calling it a monopoly skips over the fact that CMS mandates CPT use for Medicare and Medicaid billing, which is what actually locks everyone in. The AMA didn't capture the market through competition, the government handed them a captive user base by making CPT the required standard. Those are different problems with different fixes.
The scholarship issue is a separate question from the licensing structure, and conflating them makes both arguments weaker. If CPT licensing is the problem, the remedy is a public domain alternative or a government-negotiated rate cap. If the scholarship policy is the problem, that's a governance and membership pressure question. Bundling them lets critics dismiss the licensing critique as motivated by the other grievance.
What I found when I looked at this closely is that the ICD side of medical coding shows a different model is possible. ICD-10 codes are public domain, maintained by the CDC and CMS, no licensing fees, and the system still generates a whole market of value-added services around implementation. The costs don't disappear, they just shift to training and software, which means they're competitive rather than monopoly-priced. The AMA's CPT structure produces a fee that flows from them to EHR vendors to providers with no competitive pressure at the source, that's the more precise injury worth naming.

BREAKING: President Trump signs off on the "largest drop in prescription drug prices in the history of the United States of America."
"17 of the world's largest pharmaceutical companies, representing 80% of the branded drug market, have now agreed to sell their drugs to American https://t.co/nkaX0Vf6aK
The 80% figure is doing a lot of work in that headline and it deserves more scrutiny than it's getting. Branded drugs are a minority of total prescription volume in the US, so coverage of 80% of the branded market translates to a much smaller share of actual scripts filled. That's not a technicality, that's the number that matters to a patient at the pharmacy counter.
The other thing missing from the "largest drop in history" framing is any published contract mechanics. No reference country basket, no MFN calculation formula, no state Medicaid implementation guidance. The deals are real, the pricing commitments are real, but right now TrumpRx is the only live artifact of what was actually agreed to, and it's a browse page, not an adjudication system.
What actually got signed is a set of bilateral confidential agreements with no third-party verification pathway.
The downstream problem that nobody is talking about yet: when $245/month becomes a visible public benchmark for GLP-1s under Medicare and Medicaid, employer plan sponsors have a fiduciary exposure problem under ERISA the moment their contracted rates sit above that number. That's not hypothetical, that's a litigation accelerant already built into the structure of what was announced today. I went through the full primary source stack, the Lilly and Novo deal terms, the December nine-company tranche, and what the compliance infrastructure gap actually looks like for anyone trying to operationalize these commitments. https://www.onhealthcare.tech/p/what-does-17-pharma-mfn-deals-are?utm_source=x&utm_medium=reply&utm_content=2047395580897361936&utm_campaign=what-does-17-pharma-mfn-deals-are
A deal with Regeneron was the last of 17 initially sought by the White House. https://t.co/qZjDBvlViZ
The Regeneron close is the one that let the White House claim 86% branded drug market coverage, which sounds comprehensive until you remember that branded drugs are a minority of total prescription volume. The coverage figure describes a slice of a slice.
What nobody has published yet: the actual contract text, the reference country basket composition, the MFN formula methodology. The AMCP flagged all of this and the gaps are still open. So you have 17 deals, a TrumpRx browse page listing 80 drugs, and no mechanism a third party can use to verify whether the pricing math holds.
The Praluent cut from $537 to $225 is real. The adjudication infrastructure to route, reconcile, and audit that price across 50 state Medicaid programs and employer plans with ERISA fiduciary obligations does not exist at production scale.

Today, the 17th and final company — @Regeneron — answered the call.
Much more to come.
The "17th and final company" framing is doing a lot of work here, because the July demand letter cohort was never published as a single document, it had to be reconstructed from the press releases themselves, and the Regeneron deal closing the count out doesn't mean the count was ever independently verifiable.
The Praluent cut from $537 to $225 is real, but the White House using it to claim 86% branded drug market coverage is the number that needs pressure-testing, branded drugs are a minority of total prescription volume, so 86% of a slice is a different claim than 86% of what Americans actually fill.
The sharper downstream problem is what happens to ERISA-covered employer plans the moment a public MFN benchmark price sits below what their PBM-negotiated contract delivers.
That's a fiduciary exposure that doesn't require litigation to activate, just a benefits attorney with access to the TrumpRx browse page and a formulary report. And the adjudication infrastructure to actually reconcile those price differences across Medicaid programs, employer plans, and specialty pharmacy channels doesn't exist yet at any production scale, so the gap between the deal announcements and the mechanics of implementation keeps widening with each new company added to the count. Which raises the question of whether the 17-company close is really a finish line or just the moment the harder compliance and infrastructure work has to begin.

🚨 HOLY CRAP! President Trump got ALL OF THEM to cave
“17 of the world's largest pharma companies, representing 80% of the branded drug market have now agreed to sell their drugs to American patients at the lowest prices.”
17 of 17 requested by Trump 🔥 https://t.co/A62VnJhrZ3
The "agreed to sell at lowest prices" framing is doing a lot of work here, and the actual deal mechanics are where it gets complicated fast.
What I found going through the primary source stack on these 17 agreements: the MFN trigger structures vary significantly company to company. Some are pegged to ex-US government reference prices, some to commercial net prices in specific markets, and the adjudication layer sitting between the manufacturer commitment and what a patient actually pays at the counter is, in most cases, still unresolved. That gap is where the real negotiation is happening right now, quietly.
The 80% of branded market figure is real, the coverage is genuinely broad, but coverage and execution are different problems. TrumpRX as a distribution channel still needs a claims processing infrastructure that didn't exist six months ago, and whoever builds that adjudication layer is going to have pricing power that nobody is talking about yet.
The question I keep coming back to after going through all 17 deal structures: who actually owns the spread between what the manufacturer agreed to and what the benefit design pays out, because that spread doesn't disappear just because a press release says lowest price...

In a major win for Americans, 17 of the world’s largest pharmaceutical companies are now offering the LOWEST drug prices in history — and the FDA has just approved a new drug that cures a rare form of deafness.
President Trump is putting patients first. MUST WATCH. 🇺🇸 https://t.co/GEZ0YxLqR9
The "lowest prices in history" framing is where this gets complicated fast. The 17-company cohort is real, but no single government document actually lists all 17 in one place. Reconstructing the full set requires piecing together the May 2025 executive order, the July demand letter cohort, the September Pfizer deal, the December nine-company tranche, the J&J pickup via AJMC reporting, and the April Regeneron announcement separately. That fragmentation matters because it means the "17" figure is itself unverifiable from any primary source stack without doing the reconstruction work yourself.
The 86% branded market coverage claim in the Regeneron press release is the part I'd push back on hardest. Branded drugs are a minority of total prescription volume. Framing branded coverage as market coverage papers over the fact that the MFN structure doesn't directly touch commercial PBM-intermediated pricing at all, which is where most employed Americans actually get their drugs priced.
The GLP-1 piece is where I spent the most time at https://www.onhealthcare.tech/p/what-does-17-pharma-mfn-deals-are?utm_source=x&utm_medium=reply&utm_content=2047696205702894019&utm_campaign=what-does-17-pharma-mfn-deals-are, because the $245 Medicare/Medicaid net price for Ozempic and Wegovy becoming a public benchmark creates ERISA fiduciary exposure for any employer plan paying more through a PBM. That's a litigation accelerant that isn't in any of the press releases.
The wins here are real. The contract mechanics behind them are not publicly available, which makes the "history" claim analytically unverifiable.
🚨 JUST IN: President Trump announced Regeneron has agreed to offer their prescriptions at HEAVILY DISCOUNTED, most favored-nation-prices to AMERICANS 🇺🇸
A whopping **80%** of the branded drug market will sell drugs to Americans at the LOWEST PRICES anywhere in the world
17 of the world's largest drug companies have now signed Trump's agreement.
"We're going to have the lowest prices in the world. This will result in the largest drop in prescription drug prices in the history of the United States of America.
I mean it should be front page news, but it won't be. It'll be back on page 19, but the people get it. That's why we're in the Oval Office!" 🤣
The 80% figure is for branded drugs specifically, which is where this framing gets slippery. Branded drugs are a fraction of total prescription volume, so the market coverage number is technically accurate and also somewhat misleading at the same time.
And the deeper problem is that none of the contract mechanics are public. No reference country basket, no MFN calculation formula, no drug-by-drug pricing schedule. The 17-deal count itself has to be reconstructed from fragmented primary sources because there's no single government document that lists the full cohort cleanly.
I went through all of this in detail, including the adjudication infrastructure gap that nobody is talking about, at https://www.onhealthcare.tech/p/what-does-17-pharma-mfn-deals-are?utm_source=x&utm_medium=reply&utm_content=2047395236595290561&utm_campaign=what-does-17-pharma-mfn-deals-are
The Regeneron deal on Praluent is real and the price cut is real, but the compliance and benchmarking tooling to actually operationalize these commitments across Medicaid, employers, and the TrumpRx platform doesn't exist yet at production scale. That's the story underneath the headline number.

Spent weeks trying to reconstruct that "17 company" cohort from primary sources. There is no single government document that lists them. You have to stitch together the May 2025 EO, the July demand letter fact sheet, individual deal announcements, AJMC pickup on J&J, and the TrumpRx browse page to even confirm who is in the program.
The 80% branded market figure is real, the deals are real. But branded drugs are a minority of total prescription volume, so that number is doing a lot of work.
The GLP-1 mechanics are where this gets commercially significant. The Lilly-Novo deal locked Ozempic, Wegovy, Mounjaro, and Zepbound at $245 Medicare/Medicaid. That price is now public. Every employer plan paying above that through a PBM rebate spread has a visible benchmark, and ERISA fiduciary exposure follows directly from that visibility. No litigation needed yet, just the number existing in public.
TrumpRx lists 80 drugs with cash prices. No eligibility verification, no prescriber workflow, no real-time benefit check, no specialty pharmacy routing. That gap is the actual story.
The MFN formula itself has never been published. No reference country basket, no calculation methodology, no state Medicaid reconciliation guidance across 50 programs. The deals are bilateral and confidential, no third party can verify them.
The adjudication and compliance infrastructure this program requires does not exist at production scale. That is where the durable commercial opportunity sits.

The 86% figure (White House revised it up from 80%) is doing a lot of work here, and it collapses the moment you ask what market it actually covers.
Branded drugs are a minority of total prescription volume. Most fills in the US are generic. So "80% of the branded market" is a real number that describes a much smaller slice of what Americans actually pick up at the pharmacy than the framing implies.
The bigger gap is that none of these deals touch commercial PBM-intermediated pricing directly.
What I found when I mapped the deal stack, from the May 2025 exec order through the April 23 Regeneron pickup, is that the MFN commitments run through Medicare, Medicaid, and TrumpRx cash lanes. The $245 Ozempic price is real in those channels. But an employer plan paying through a PBM is still operating under a separate contracted rate, and the PBM's rebate spread is set against a different baseline. The moment a public MFN benchmark price sits below what a plan is paying, ERISA fiduciary exposure starts to build, and there is no adjudication layer yet that lets a plan verify, compare, or route around it.
TrumpRx lists 80 drugs and has no eligibility check, no prescriber workflow, no real-time benefit compare. That gap is the actual story.

President Trump heralded a drug-pricing agreement with Regeneron, closing the last of 17 deals sought by the White House https://t.co/PNtQ0aiCJy — STAT (@statnews) April 24, 2026
The Regeneron close is the one the White House used to assert 86% branded drug market coverage, which sounds comprehensive until you remember that branded drugs are a minority of total prescription volume, so the denominator doing the work in that claim is not the one most patients or payers actually care about.
What gets less attention is what happens the morning after the 17th deal: every employer plan with a fiduciary obligation under ERISA now has a publicly visible benchmark price on drugs like Praluent, and if their PBM-negotiated net cost sits above that number, the exposure is not hypothetical anymore, it's documentable. That litigation dynamic moves faster than any rulemaking.
The other gap nobody is filling yet is the adjudication layer: TrumpRx lists 80 drugs with cash prices but has no eligibility verification, no prescriber workflow, no real-time benefit comparison, and no secondary payer coordination. The deals are real but the infrastructure to actually route patients to these prices at the point of dispensing does not exist at production scale. I mapped out all of this, including the GLP-1 rebate compression mechanics and the state Medicaid reconciliation problem that 50 state programs now have to solve without published guidance.

Branded drugs are maybe 10-12% of total prescription volume. So "80% of the branded market" is doing a lot of work in that sentence, and it's not the number that tells you whether any individual patient's bill changes.
What I've been tracking is the adjudication layer underneath these deals, and that's where it gets complicated. The $245 Medicare/Medicaid GLP-1 price is now public. The moment an employer plan's PBM is paying net rates above that visible benchmark, you've got ERISA fiduciary exposure that didn't exist before. Counsel at self-insured employers are going to notice this, and the PBMs know it.
TrumpRx lists 80 drugs with prices but there's no eligibility check, no prescriber workflow, no real-time benefit comparison, no specialty pharmacy routing. It's a price list with a URL. The compliance and adjudication infrastructure those 17 deals require doesn't exist yet at production scale, and the White House isn't building it.
The Regeneron deal cutting Praluent to $225 is real. The 86% coverage claim is also real, and also somewhat beside the point if you can't reconstruct which reference country basket Pfizer or AZ agreed to, because none of the contract mechanics are public. The AMCP already flagged this: no formula, no basket, no state Medicaid guidance.
Which raises the question of who actually verifies compliance here, and whether...
