Doesn't Sam Altman famously not own OpenAI? His whole arrangement is so shady.
So a non-profit can absolute invest in or own a for-profit subsidary. This is extremely common. The idea is that the for-profit returns will flow back to the non-profit and remain dedicated to the non-profit mission.
Where things get really shady and run the risk of IRS violations is when the leadership of the non-profit has a seperate for profit stake in the subsidary.
Is there a more benign explanation for these things? Altman is undeniably famously cagey and political but despite most of the tech and non-tech worlds at this point seeing him as some kind of con artist, I still kind of want to try to believe he's not.
No doubt some of OpenAI's founding principles like "stop + assist if a competitor gets to AGI first" are likely flying out the window, perhaps in part due to him and also as one might anticipate of initial lofty ideals and promises, but even with the recent New Yorker and other articles he seems like someone who maybe regularly placates people to avoid personal problems and lies to get out of trouble rather than a Machiavellian tech baron.
Sam has stake in Y Combinator from when he was CEO, who also has an ownership stake in OpenAI.
So to say that he owns no part of OpenAI is silly.
