Chai Discovery's $130M Series B and the open-source Chai-1 protein-structure model put the category back in conversation against AlphaFold 3 and Isomorphic Labs. Recursion and Tempus operate the largest phenomics and clinical-genomics datasets in the public-comparable set, while Insilico Medicine pushed its first generative-AI-designed molecule INS018_055 into Phase II for IPF. Owkin partners with hospitals on federated learning, EvolutionaryScale shipped ESM3 as a frontier protein language model, and Xaira Therapeutics launched in 2024 with one of the largest seed rounds in biotech history. Atomwise, Cradle, Latent Labs, and Iambic round out the computational-chemistry layer.

Key trends 2026
- Foundation-model biology arrives. Chai-1, ESM3, and AlphaFold 3 reset the structure-prediction baseline for in silico screening.
- Phase II readouts begin. Insilico's INS018_055 IPF program gives the first generative-AI-discovered drug a real clinical signal.
- Federated data beats centralized scraping. Owkin's hospital network model sidesteps the patient-data licensing wall that blocks others.

FAQ
Frequently asked
Which AI drug-discovery startup has raised the most?
Among our tracked startups Chai Discovery leads at $130M Series B. Public peers Recursion and Tempus have raised more historically (Recursion $400M+ pre-IPO, Tempus IPO 2024) but trade as listed companies rather than VC-staged startups.
Has any AI-designed drug reached clinical trials?
Yes. Insilico Medicine's INS018_055 for idiopathic pulmonary fibrosis advanced into Phase II — the first molecule with both target identified and structure designed by generative AI to reach that stage. Several Recursion and Iambic candidates are in Phase I.
What does Chai-1 give researchers that AlphaFold 3 doesn't?
Chai-1 ships with weights downloadable for non-commercial research and matches AlphaFold 3 on ligand and antibody benchmarks. AlphaFold 3 is gated behind Isomorphic's web server with usage caps, which limits high-throughput in-silico screening pipelines.
