The courtroom fight between Elon Musk and OpenAI moved closer to a jury trial in Oakland on Monday, with the dispute threatening to reshape who runs the AI company and how it is ultimately organized.

Elon Musk took the stand as the high-profile trial over the future of OpenAI kicked off on Tuesday — claiming that CEO Sam Altman took control of a group founded as a “charity” and improperly morphed it into a money-minting corporate juggernaut.
