AI in Healthcare

Where the capital is concentrating, where the moats actually are, and where a disciplined investor should — and shouldn't — deploy.

The Argument in One Breath

The durable returns in healthcare AI accrue not to the best model but to whoever owns the proprietary data loop and the workflow distribution. Back the infrastructure and workflow layer where switching costs compound; rent exposure to drug-discovery platforms only against de-risked clinical readouts, not promises.

Sector Overview — The Setup

Healthcare AI has crossed from narrative into spend. In 2025, U.S. digital-health startups raised $14.2 billion — the highest total since 2022 and a 35% jump on 2024 — with AI-enabled companies capturing 54% of those dollars, up from 37% a year earlier. On the broader healthcare-investment lens that includes biopharma and devices, AI absorbed more than $18 billion, roughly 46% of all healthcare investment for the year.

The defining feature of this cycle is not growth — it is concentration. Deal count is falling even as deal dollars rise. Q1 2026 saw global digital-health funding of $7.1 billion across only 216 deals: a slight decline in value but an 83% surge in average check size. Capital is consolidating into fewer, later-stage, AI-native winners. Roughly 29% of disclosed healthcare-AI rounds now exceed $200M, and median round size in pure-play healthcare AI has climbed to an unusually high ~$103M.

The cycle signal: this is no longer a seed-stage land grab. It is an early consolidation phase, where a handful of category leaders are being capitalized to win — and the alpha is in identifying which categories produce durable winners versus which collapse into commoditized features.

Structural Tailwinds — Why Now

The obvious tailwinds are real: clinician burnout, a structural labor shortage, an ageing population, and language models finally good enough to handle unstructured clinical conversation. Over 70% of large hospital systems worldwide now use AI in at least one clinical domain. But the obvious case is priced in. The investable insight sits one layer deeper.

First-order: the ROI is now provable

Documentation burden has moved from a soft satisfaction problem to a hard financial one. At WVU Medicine, clinicians reported 78% more undivided patient attention and 77% higher work satisfaction after ambient AI rollout. When ROI is measurable, procurement cycles compress and budgets shift from innovation pilots to operating expense.

Second-order: the IPO window reopened, re-rating the private stack

After a two-year drought, six “Health Tech 2.0” companies went public across 2024–25 — Waystar, Tempus, Hinge Health, Omada, Caris, and HeartFlow — adding $36.6 billion in fresh market cap. Critically, these came to market profitable or near-profitable, not as hype vehicles.

A credible public exit path re-prices every private round behind it. It gives crossover funds a reason to underwrite later-stage rounds at scale — which is precisely why mega-rounds are exploding. The exit window, not the technology, unlocked the 2025–26 capital surge.

Third-order: regulatory friction is a moat, not just a cost

In an AI world, regulation inverts. Compliance burden, clinical validation, EHR integration, and HIPAA-grade data handling create exactly the friction that horizontal AI labs cannot easily cross. Regulation is the wall that keeps frontier labs out of your cap table’s TAM.

Competitive Dynamics — Who Wins and Why

The central question is the same in every segment: does the model commoditize, and if so, what doesn’t? Foundation models are converging and getting cheaper. Any thesis built on “our AI is better” is renting an advantage. The durable moats are elsewhere.

Moat typeWho holds itWhy it’s defensible
Proprietary data loopTempus, CarisClosed-loop genomic + clinical + imaging data can’t be scraped; it compounds per patient.
Workflow lock-inAbridge, AmbienceOnce embedded across thousands of seats, switching cost is organizational.
Regulatory validationFDA-cleared incumbentsYears of trials and clearances are non-replicable by a fast follower.
Platform controlEpic + Microsoft/NuanceOwns the system of record; can bundle “good enough” AI at near-zero marginal price.

The investable read: in documentation AI, the note itself is going to zero. The winners convert the ambient-listening beachhead into the revenue-cycle and coding stack — workflows that touch money, carry higher switching costs, and Epic is slower to absorb.

Investment Thesis — The Argument

Core Thesis

In healthcare AI, the model is a depreciating asset; the proprietary data loop and embedded clinical workflow are the appreciating ones. Overweight the infrastructure and workflow-platform layer, deploy at growth stage, and treat AI drug discovery as a separate, option-like sleeve underwritten only against de-risked clinical readouts.

The thesis resolves into three positions of decreasing conviction:

  • Highest conviction — own the data/workflow infrastructure. This is where the moat survives model commoditization. Switching costs are organizational; data assets compound.
  • Selective — back documentation platforms escaping their category. Only those expanding into coding, RCM, and revenue integrity before the EHR commoditizes the note.
  • Optional / convex — the drug-discovery sleeve. The largest TAM, but 2026 is the year of binary Phase III tests. Pair platform exposure against asset-stage names only after readouts.

The drug-discovery nuance most theses miss

The popular framing — “AI compresses 10-year timelines to 18 months” — describes the front page, not the P&L. The bankable value in 2026 is the unglamorous back end: trial operations, regulatory documentation, manufacturing, and pharmacovigilance. Front-end molecule generation remains unproven at scale; the ~90% clinical failure rate has not yet been beaten by AI-designed compounds. Underwrite the picks-and-shovels, not the lottery ticket — until a Phase III says otherwise.

Risk Factors — What Could Kill the Thesis

Platform commoditization (highest probability)

Epic + Microsoft bundling "good enough" AI natively into the EHR could collapse pricing for the entire workflow layer before startups escape into adjacent revenue-touching products.

Clinical failure in drug discovery (highest severity)

2026 delivers the first large-scale Phase III tests of AI-designed drugs. A high-profile failure could re-rate the entire AI-pharma category downward.

Valuation & concentration risk

~$103M median rounds and ~$5B marks on pre-profit workflow companies price in flawless execution. With capital concentrating in a few names, one stumble marks down comparables across the book.
