Musk says he was alarmed upon hearing about a $10 billion investment from Microsoft around 2022. “I reacted quite negatively because at a 10 billion scale there’s no way Microsoft is just giving that as a donation or any charitable way,” he says. He texted Altman that “I was disturbed to see OpenAI with a $20B valuation. De facto. I provided almost all the seed, A and B round funding.” An exhibit shows Altman responded: “I agree this feels bad, we offered you equity when we established the cap profit but you didn’t want at the time which we are still very happy to do any time you’d like.” Musk says he asked for a legal investigation and at this point had lost faith in OpenAI.
