Quoting John Gruber

Simon Willison's AI Notes published: So it’s well known that Y Combinator owns some stake in OpenAI. But how big is that stake? This seems like devilishly difficult information to obtain. I asked around and a little birdie who knows several OpenAI investors came back with an answer: Y Combinator owns about 0.6 percent of OpenAI. At OpenAI’s current $852 billion valuation , that’s worth over $5 billion. — John Gruber , Y Combinator’s Stake in OpenAI Tags: openai , y-combinator , ai , john-gruber
