Breaking: Anthropic files confidential S-1 with SEC for IPO, less than one week after $65B raise. But is this Peak AI?

It’s raining mega-IPOs. One week after Oura’s filing a confidential S-1 with the Securities and Exchange Commission for its IPO, massively bigger Anthropic, the developer of Claude AI, has done the same. As with Oura, neither share price nor number of shares has been disclosed in this preliminary filing. Anthropic release

The S-1 filing comes on top of their 28 May announcement of a $65 billion Series H funding led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. The valuation of $965 billion makes Anthropic the most valuable AI company on Planet Earth and perhaps the entire Solar System, surpassing OpenAI by about $113 billion. Anthropic’s valuation in February was $380 billion with their Series G raise, so the Series H valuation multiplied that by a stunning 2.5 times+ in three months. The new funds will be used for AI research, expanding its computing power for Claude, and scaling its products and partnerships.  CNBC, Mobihealthnews, Anthropic release

Anthropic’s over-the-top valuation was boosted by its projected annual revenue run of $50 billion, tipping into profitability this quarter, beating its own growth metrics regularly, and introducing new Claude products such as Claude Opus 4.8 and Claude Mythos Preview with advanced cybersecurity available to a limited group of companies. Anthropic in January rolled out Claude for Healthcare for providers and consumers. Claude pulled in front in corporate sales, ahead of OpenAI, as of April, and last month inked a new partnership with Bristol Myers Squibb to implement Claude throughout the company.

But are we at Peak AI? Axios, never one to shy away from Cold Buckets of Water when it makes for a good lede, has been trumpeting for the past week that companies are suddenly shying away from their “discovery” of soaring AI costs. Suddenly, ballooning IT costs, uncertain productivity gains, and a strange combination of employee overuse and sudden skepticism are causes for concern. An AI consultant told Axios that employees blew through half a billion dollars in a single month because they didn’t put usage limits on Claude licenses. Then the CEO of an AI software company, CloudBees, admitted that companies are using workforce cuts to offset their soaring AI costs. This has to be one of the worst-kept secrets in corporate America. Even a casual peruser of LinkedIn would have known this a year ago.

Corporate adoption in Axios‘ view is running into four expensive headwinds such as:

  • Using AI to automate disliked tasks rather than prioritizing revenue-generating tasks–which is understandable without guidance and pressure on time.
  • Using AI for trivial tasks such as checking the weather (well, no one said they couldn’t)
  • Leadership is clueless on what AI tools work and are throwing licenses at the employee wall to see what sticks.
  • Reluctance to give AI models proprietary information, which makes the AI tool less effective. (Not feeding AI models proprietary information to prevent it from becoming public in LLM models is, one would believe, an understandable concern.)

Even OpenAI’s Sam Altman commented when Anthropic’s Series H was announced that corporate costs are the most valid concern to date.

Unless there is a massive enterprise pullback in AI spend, though, look to Anthropic floating that IPO no later than the fall, even if corporate AI spend pulls back.

A Must-Read potpourri: the ‘math’ of AI data center builds, healthcare AI failures, telehealth in schools, Hippocratic AI’s problems, the loss of empathy.

Your Editor will be Away From The Desk more than a bit over the next two weeks that lead up to the US Memorial Day holiday. I’ve collected seven articles to read and consider over the next few days. Enjoy!

Where Are All The Data Centers?

Author: Ed Zitron.  Self-published on Where’s Your Ed At?

If you’re puzzled about the ‘math’ of data centers–what capacity is available now, what is actually online/operational, and what’s the pipeline like–you will appreciate the detail that Mr. Zitron has gone to in cataloging those and much more. It turns out that we are not in the Land of Math, but in the Land of Myth, ruled by the Great Oz.

Despite what the builders say, and Microsoft’s and Oracle’s ever-cheery press releases, operational data centers are a fraction of what’s needed now or projected. The centers take 18-24 months to build and then many more months to complete–to fit out with chips, cooling, power, and networking that links sites and the end users. The AI giants, despite all the money flowing their way, will run out of money before the operating capacity they need gets online. Every data center takes 18-24 months to build, and even with retrofitting older data centers, the capacity is not there, nor for some time to come. In other words, the cavalry is in a neighboring country, much less the next state. Nobody has yet built an operating 1 GW data center. Centers are in megawatts and that, not many MWs. 

FTA:

  • “Oracle is building 7.1GW of total capacity for OpenAI, and keeps — laughably! — saying 2027 or 2028, when at this rate, Stargate Abilene won’t be done until mid-2027, and the rest either never get finished or are done in 2030 or later.”
  • “This is setting up a horrifying situation where Oracle desperately needs OpenAI to pay it for capacity that doesn’t exist, and if it ever gets built, it’s likely to be years after OpenAI has run out of money, which is the same problem that Microsoft, Google, and Amazon have with their $748 billion of deals with Anthropic and OpenAI, though thanks to the $340 billion or more necessary to build the Stargate data centers, Oracle’s problems are far more existential.”

The article also makes the point that Oracle does not have the fallback businesses that Microsoft, Google, and Amazon have to cushion the blow of AI failure. Oracle has the bottomless pit of Oracle Health, only one part of which is the VA EHR. It has a crushing burden of a massive debt load, the most recent being financed by a large bond fund since banks wouldn’t touch it. It kicked 30,000 employees and their expertise  to the curb. Will Larry Ellison sell a yacht or an island to help finance this as a 40% owner? More in Oracle Steps Back From The Debt Brink and Oracle’s Rock and Hard Place in Abilene

This is one long, well-written, and researched analysis by Mr. Zitron, whose expertise is in PR and is a well-known Silicon Valley critic. 

Telehealth in Schools: Expanding Student Access in a Hybrid Health Care System

Author: Paul Samargedlis. Published on Telehealth.org

Healthcare shortages across the US are affecting K-12 schools and children’s health. School-based telehealth programs can reduce absenteeism, expand access to mental health care, and deliver preventive care, bringing that care to where children already are. School-based telehealth programs in states such as Texas and North Carolina have demonstrated measurable improvements in attendance and emergency department utilization. Much will have to change in coordinating efforts and obtaining funding among school systems, local providers, and governments.

Artificial Intelligence Acquisitions: Agencies Should Collect and Apply Lessons Learned to Improve Future Procurements

Author: Government Accountability Office (GAO) Report to Congressional Requesters. April 2026 (49 pages)

Federal agencies reportedly more than doubled their use of artificial intelligence (AI) from 2023 to 2024, and they used a range of approaches to acquire additional AI capabilities through fiscal year 2025. In April 2025, the Office of Management and Budget (OMB) issued guidance to help agencies acquire AI responsibly, but agencies have not by and large shared that knowledge. This paper attempts to fill this gap in part. GAO identified trade-offs, challenges and benefits. The paper identifies approaches agencies made in acquisition and makes recommendations. The recommendations most impact DOW, DHS, GSA, and the VA.

Top AI Failures in Healthcare

Author: Dmitrii Gorbunov. Published on LinkedIn.

Mr. Gorbunov sums up five costly failures (or about to be failures) where AI has been used in healthcare: physician decision overrides (UnitedHealthcare), claims denials (Cigna), fabrications of consent documents (Sharp Healthcare), and adding diagnostic codes without physician confirmation (Kaiser Permanente). The fifth one, Doctronic, was spoofed by Mindguard to issue triple the dose of Oxycontin [TTA 26 Mar]. The lack of rules, audit and audit trails that can be confirmed and trusted will cost healthcare organizations money and already are having legal consequences.

The Architecture of Voice: Why AI Tools Can Mimic Style But Not The Voice

Stuart Miller (Haverin Consulting)’s fourth article on AI’s effect on language and writing. An AI LLM can partly fill two parts of the Competence Framework–Skills and Knowledge–but it does not have Experience. It is incomplete in these three points of Context, and Voice represents the accumulation of Context. FTA: “The dangerous part is the assumption that accelerated Knowledge substitutes for Experience, when in fact accelerated Knowledge, and improved Skills untethered from time, is precisely the recipe for the Builder’s Mirage. The Builder’s Mirage is the illusion of competence, produced without the underlying thing being present.”

Hippocratic AI Fires Its International Sales Team

It’s turning into Theranos 2.0. FTA: “Revenue is an estimated $17–20M ARR. Burn rate is $404M.” Their customers are also their investors. and Hippocratic AI has quietly withdrawn from all of its international markets, terminated every international contract, and let go of the international sales team that built those relationships.Contracts were sold without country language versions, adequate GPU infrastructure, and compliance.

Christina Farr: “Where is all of our empathy? Where did it go?”

Christina Farr is the former CNBC healthcare tech reporter, founder of  Second Opinion Media, and is a funder/advisor in the field. The article is derived from his and Alex Koshykov’s interview for their podcast Digital Health Inside Out (48 minutes, go to YouTube, no paywall). “A no-holds-barred conversation about what’s broken in healthcare media, what’s about to break in digital health, and why she’s not coming back to journalism.”

Until next week….

Funding/deal roundup: WHOOP’s $575M Giant raise, Anthropic buys med AI startup for $400M, early stage fundings for Jimini, Insight Health; Noom buys compounder; Mount Sinai NY to embed OpenEvidence

Deals lately are very large…or very small. All have “AI” somewhere. Some unusual ones this past week.

The WHOOP wearable definitely whooped it up with a $575 million Series G (for Giant) funding. It’s a fitness and health watch that is reasonably trim and presentable sans a screen. It tracks sleep, activity, heart health and menstrual cycles (if applicable) through measurement of heart rate variability (HRV), resting heart rate (RHR), respiratory rate, and blood oxygen levels, and appeals to the very athletic with metrics around recovery and strain. The Boston-based company claims 2.5 million members internationally; in 2025 it marked 2025 growth of 103% and exited at the infamous ‘run rate’ metric of $1.1 billion. Their AI twist is around biometric data and how it is used to guide tracking and performance. It is heavily pitched to elite sports with famous athlete endorsers/investors such as soccer star Cristiano Rinaldo, basketball’s LeBron James, and golfer Rory McElroy.

The round was led by Collaborative Fund and includes global participation from a gang of investors including 2PointZero Group, Qatar Investment Authority (QIA), Mubadala Investment Company, Abbott, Mayo Clinic, Macquarie Capital (entities administered by Macquarie Capital), Glade Brook, B-Flexion, IVP, Foundry, Accomplice, Affinity Partners, Promus Ventures, and Bullhound Capital alongside a group of prominent global athletes and individual investors. The additional funds will be used for growth in the US plus international expansion across Europe, the GCC, Latin America, and Asia. The wonderfully subjective (by investors) metric of valuation stands at $10.1 billion. Total funding since 2012 is over $900 million.

WHOOP received the infamous Warning Letter from FDA’s Center for Devices and Radiological Health (CDRH) in July 2025 regarding marketing claims for Blood Pressure Insights (BPI) on the basis that the company did not have an approved application for premarket approval (PMA) or 510(k) approval of that feature. The founder/CEO is contesting FDA as he believes that the feature is for general wellness purposes and is covered under the 21st Century Cures Act.  Mobihealthnews, WHOOP release

(In all honesty, this Editor had only vaguely heard of it, but her idea of a expensive watch usually has the name Elgin or Hamilton on the face and is usually antique (Omega too, sigh). In fitness watches, she thinks of Apple, Samsung, and the low-profile Withings (which makes traditionally styled smartwatches) but none of them have persuaded her to part with several hundred dollars.)

Anthropic buys a tiny bio research software developer for a stunning $400 million in stock. Coefficient Bio was founded only eight months ago and reportedly had only nine employees. It was so stealthy that it never got past the placeholder website. The amount was reported by its 50% owner, venture capital firm Dimension, which realized a hefty 38,513% IRR on the investment. Coefficient was working on AI models and software for biological research.  Apparently founder Samuel Stanton and his team will join Anthropic’s Health Care Life Sciences area. It’s interesting that Anthropic is building up their healthcare footprint after making their customized AI available to both consumers and clinicians, quite a contrast to OpenAI’s purchase of TPTN, a small podcaster of tech news and personalities (CNBC).

Early stage companies also nabbed some decent fundings

Behavioral health therapy assistant Jimini Health raised $17 million in seed funding from M13, Town Hall Ventures, LionBird, Zetta Venture Partners, and OneMind, bringing total funding to more than $25 million. Their AI-forward (of course) Sage platform fills the niche left by fully remote telementalhealth companies in supporting large behavioral health provider organizations. NYC-based Jimini  promotes a clinician-supervised and controlled patient-facing, reimbursement-ready and compliant infrastructure with licensed clinicians maintaining oversight of every patient interaction. According to the release, the funding will be used to build partnerships with “several of the largest behavioral health provider organizations in the country and expand Sage’s clinical capabilities across comorbidities, care settings, and patient engagement modalities”. Release, Behavioral Health Business, Mobihealthnews

Insight Health’s $11 million Series A will be used to scale its agentic AI platform. The round was led by Standard Capital, with participation from Kindred Ventures, Pear VC, Eudemian, 43 and ElevenLabs. Insight Health uses AI to automate routine clinical and non-clinical tasks such as phone and front-desk coordination, referral and fax processing, pre-clinical intake, and clinical documentation. For instance their agents engage with patients directly via voice or text. Current customer base is in clinics. Their Aura AI Scribe and Virtual Care Assistant are available in athenahealth’s Marketplace. Their total funding is about $16 million. Release, Mobihealthnews

Short takes:

Noom buys 503A licensed pharmacy Tailor Made Compounding (TMC). The buy, according to Noom, will enable them to expand beyond weight loss GLP-1s further into the healthy aging segment, with longevity peptides, hormone replacement, and cosmetics. Noom has weathered several pivots, starting in 2008 with fitness apps, then added behavioral change with a weight-loss coaching app in 2017. It has pretty much settled into the lucrative e-prescribing and wellness ‘preventative care’ area targeting health plans and employers. TMC’s client base includes 400 clinics and multiple telehealth partners, which presumably Noom will let them maintain. Acquisition cost and staff transitions were not disclosed beyond integration ‘later this summer’.  Release, Mobihealthnews

‘IT’ clinical information search engine/AI chatbot OpenEvidence inks deal with NY’s Mount Sinai Health System. It is Mount Sinai’s first enterprise-wide AI deployment and integration across clinical roles, according to the health system’s announcement last week. It will be integrated into their Epic EHR. OpenEvidence, with a eyeblinking valuation of $12 billion [TTA 13 Feb], claims a daily average usage by 40% of US doctors in 10,000 hospitals and medical centers of their free search engine trained on journals and clinical medical data only. It fills a gap that competitors Doximity, Epocrates, and Medscape aren’t doing. It has added clinical trial matching to its capabilities filtering trials by study design, enrollment status, and geographic proximity. This adds on to Sutter Health’s integration into doctors’ Epic workflows announced earlier this year. Healthcare IT News
