OpenEvidence Raises $250M at $15B, 25% Above January's $12B Mark and Weighing Sale

Business Insider reports that OpenEvidence, the AI clinical search engine used by roughly 40% of US physicians, quietly closed a $250 million round at a $15 billion valuation — up from the $12 billion mark set by its January 2026 Series D and its second doubling in nine months. Sources say the founders are fielding acquisition interest and could be open to selling the company rather than pushing on to IPO. The raise follows Sacra estimates that OpenEvidence hit roughly $300 million in annualized revenue by mid-2026, cementing it as one of the fastest-scaling vertical AI companies in healthcare.
