Medical AI Startup OpenEvidence Reaches $15 Billion Valuation

OpenEvidence, an AI medical search platform often called the "ChatGPT for doctors," reportedly raised $250 million in a new funding round led by hospital systems and Andreessen Horowitz, driving its valuation up to $15 billion. This follows a previous valuation of $12 billion in January, bringing its total funding raised over the past year to more than $1 billion. The rapid valuation surge highlights intense investor interest in domain-specific AI tailored for healthcare as tech giants like OpenAI and Anthropic aggressively expand their own clinical tools. Furthermore, OpenEvidence's established footprint among medical professionals makes it a prime acquisition candidate for companies looking to instantly gain clinical traction and secure valuable compute infrastructure. More than two-thirds of U.S. physicians now use OpenEvidence to assist with diagnosis and treatment decisions. Insider reports note that the company may consider a sale, partly to secure long-term compute capacity as data center infrastructure faces potential bottlenecks.
