# Chai Discovery Raises $400M Series C for AI Drug Discovery

> Chai Discovery has raised a $400 million Series C that values the AI drug-design startup at $3.8 billion, announced July 14 and led by Index Ventures with Kleiner Perkins, Sequoia, and Dimension. The valuation is roughly triple where the company stood just seven months earlier, a jump that captures how hot AI biotech has become. Founded in 2024 by a team drawn from DeepMind and academia, Chai builds AI models for molecular design and drug discovery, the kind of work that aims to compress years of pharmaceutical trial and error into faster computational search. The raise gives it the capital to scale that effort at a moment when investors are betting heavily on AI reaching into the life sciences. The pace of the markup is its own story. A near-tripling in seven months says less about any single result than about how much money is flowing toward the idea that AI can meaningfully accelerate how new drugs are found.
