The fight here is not really about one bad board meeting or one spicy text thread. It is about who gets to control one of the most important AI companies on earth — and whether OpenAI was allowed to evolve from a nonprofit mission into something much more commercial. That is why Elon Musk being back on the stand matters. On April 29 in federal court in Oakland, he spent another day under questioning, defending his claim that OpenAI and Sam Altman broke the original deal.

He says OpenAI was founded in 2015 as a nonprofit meant to build advanced AI for humanity, not for private enrichment, and that he gave money and credibility to that mission.

If Musk wins major remedies, the court could disrupt OpenAI’s governance, limit who controls it, and complicate relationships with investors and partners. Even if he loses, the trial is dragging internal decisions, old emails, and governance choices into public view. (cnbc.com) exposure changes how counterparties think about risk. That part is bigger than the courtroom theatrics. (aol.com) ### What is the real bottom line? Musk’s second day on the stand did not settle the facts. But it clarified the stakes.
