Elon Musk’s lawyers faced off with OpenAI in court Tuesday as a federal judge weighed the billionaire’s request for a court order that would block the ChatGPT maker from converting itself to a for-profit company.

A federal judge weighed in Tuesday on a long-brewing legal feud between billionaires Elon Musk and Sam Altman over OpenAI, suggesting she’s unlikely to halt the company’s plan to restructure for now.

Musk’s request to block OpenAI’s conversion is the latest move in a grudge match between the world's richest person and OpenAI CEO Sam Altman.

Elon Musk's lawsuit against OpenAI on its shift to a for-profit entity might go to trial, ruled a federal judge. Musk co-founded OpenAI, and his legal move highlights tensions over its corporate restructuring.

Elon Musk asked a judge to block OpenAI's attempt to transition from nonprofit to for-profit. It's not the first time he's feuded with CEO Sam Altman.

A preliminary injunction stopping OpenAI’s conversion to a for-profit company is unlikely in a case of “billionaires versus billionaires,” said the judge.

The injunction Musk asked for would freeze OpenAI's transformation to a more conventional, public benefit for-profit company, just as it's in talks to raise as much as $40 billion in a funding round

A federal judge said on Tuesday that parts of Elon Musk's lawsuit against OpenAI to halt its conversion to a for-profit entity might go to trial, adding that the Tesla CEO will have to appear in court and testify.
