Coefficient Bio: Everything to know about Anthropic’s $400 million biotech acquisition
Anthropic is making strides in the AI space. The AI firm has acquired stealth startup Coefficient Bio for over $400 million in an all-stock deal. Closed in early April 2026, the acquisition pulls a tiny team of elite ex-Genentech researchers into Anthropic’s Healthcare and Life Sciences group, pushing the AI lab’s ambitions beyond smart chatbots into drug discovery.
Founded in late summer 2025 in New York City, Coefficient Bio has operated in near-total stealth for just 7-8 months before its explosive exit. Backed heavily by Dimension, which reportedly held about half the company, the startup assembled fewer than 10 experts focused on AI-native biotech tools.
