OpenAI Lines Up a $30B Bridge at $1.25T; Microsoft Researchers Crack a 31-Year-Old Math Problem With AI Agents — October 23, 2026

OpenAI is reportedly closing an up-to-$30 billion round at a $1.25 trillion pre-money valuation, led by UAE investors and Coatue, while efficiency neolab Flapping Airplanes raises $1 billion. Microsoft Research details how human-directed AI agents helped prove the KLS conjecture, and Recursive ships Flint, a 40B open coding model that runs on a laptop.
