Overview
- Anthropic has reportedly acquired stealth startup Coefficient Bio in an all-stock deal just over $400 million, based on a letter obtained by Newcomer.
- Neither Anthropic nor Coefficient Bio has given on-the-record comment in response to the reports.
- Coefficient Bio, founded in September 2025 by ex-Genentech Prescient Design researchers Nathan Frey and Samuel Stanton, builds AI that automates lab work such as drug R&D planning and clinical regulatory strategy.
- Reports say the team will join Anthropic’s Health Care Life Sciences group led by Eric Kauderer-Abrams.
- The purchase would be Anthropic’s third known acquisition and aligns with a push toward a possible IPO after a $30 billion Series G that reportedly valued the company at $380 billion.
