OpenAI CFO says company in funding talks at valuation nearly 50% above March round

The signal here is momentum rather than a number: a reported step-up of nearly half again on the March mark implies private buyers are still willing to underwrite OpenAI's capital needs at a steep premium, even with the round's size and terms undisclosed. That matters most for the private AI names whose valuations are benchmarked against OpenAI, and for the crossover funds and strategics competing to get into the cap table. Whether the talks convert into a closed round at that level, and on what structure, is the open question.
