Generate:Biomedicines just announced Phase 3 trials for GB-0895, an antibody entirely designed by AI, recruiting patients from 45 countries as of late 2025. Isomorphic Labs has human trials "very close." That's not hype. That's proof that AI-designed drugs work in humans.
And the market hasn't priced this in yet.
Generative biology, applying the same transformer architectures behind ChatGPT to protein design doesn't incrementally improve drug discovery. It compresses it. Traditional timelines: 6 years from target to first human dose. Generative biology: 18-24 months. That's not faster iteration. That's a category shift.
Here's what's actually happening: A handful of well-funded companies have already won the scaling race. Profluent's ProGen3 model demonstrated something critical that scaling laws (bigger models = better results) apply to protein design just like they do to LLMs. The company raised $106M in Series B funding in November 2025. EvolutionaryScale built ESM3, a 98-billion-parameter model trained on 2.78 billion proteins, and created novel GFP variants that simulate 500 million years of evolution computationally. Absci is validating 100,000+ antibody designs weekly in silico, reducing discovery cycles from years to months.
These aren't startups anymore. They're infrastructure.
The Market Opportunity Is Massive, But Concentrated
The AI protein design market is $1.5B today (2025) and grows to $7B by 2033 (25% CAGR). Protein engineering more broadly: $5B → $18B in the same window. But here's the friction: success requires vertical integration. Algorithms alone are defensible for exactly six months. What matters is the ability to design, synthesize, test, and iterate at scale: wet lab automation, manufacturing readiness, regulatory playbooks.
Generate raised $700M+ because it built all three. Profluent raised $150M because it owns the data and the model. Absci went public because it combined proprietary platform with clinical validation. The solo-algorithm play? Dead on arrival.
This matters for founders evaluating entry points. The winning thesis isn't "better protein design." It's "compressed drug discovery + manufacturing at scale + regulatory clarity." Pick one of those three and you're a feature. Own all three and you're a platform.
Follow the Partnerships, Not the Press Releases
Novartis: $1B deal with Generate:Biomedicines (Sept 2024). Bristol Myers Squibb: $400M potential with AI Proteins (Dec 2024). Eli Lilly + Novartis: Both partnered with Isomorphic Labs. Corteva Agrisciences: Multi-year collab with Profluent on crop gene editing.
These deals aren't about technology proving. They're about risk transfer. When Novartis commits $1B and strategic alignment, they're not hedging on whether AI-designed proteins work they're betting on speed-to-market mattering more than incremental efficacy improvements. That's a macro signal: pharma's risk tolerance is shifting from "is it better?" to "can we deploy it in 36 months?"
For investors, this is the tell. Follow where the check sizes are growing, not where the valuations are highest.
The Real Risk Isn't Technical—It's Regulatory and Biosecurity
Can generative biology design novel proteins? Yes. Can those proteins fold predictably? Mostly. Will they work in vivo? That's the test happening right now in Phase 3 trials.
But the bigger risk is slower: regulatory alignment. Agencies are adapting, but they're not leading. Gene therapy has 3,200 trials globally. Only a fraction navigated the approval gauntlet successfully. AI-designed therapeutics will face the same friction unless founders invest heavily in regulatory affairs early not late.
And then there's dual-use risk. Generative biology lowers barriers to misuse. AI models could design pathogens or toxins for bad actors. This isn't hypothetical, it's why 94% of countries lack biosecurity governance frameworks. Founders that build secure-by-design architectures and engage proactively with regulators on dual-use mitigation will differentiate themselves sharply from those that don't.
The Next 24 Months: Clinical Data Wins. Everything Else Is Narrative
Generate's Phase 3 readout will determine whether the market reprices generative biology from "interesting" to "inevitable." If it works, expect a flood of follow-on funding, accelerated IND filings, and a stampede of partnerships. If it fails or if safety signals emerge you'll see valuation compression and investor skepticism that lasts years.
For founders: don't chase market size. Chase clinical validation. For investors: don't chase valuations. Chase clinical milestones.
The inflection point is here. The question is whether you're positioned to capture it or just watch it pass.
