Elon Musk lost the latest battle in his lawsuit against OpenAI, but a judge appears to have given the billionaire reasons to be hopeful.

In a significant clash of tech titans, Elon Musk and Sam Altman find themselves at odds over the future direction of artificial intelligence (AI) as their respective companies, xAI and OpenAI, vie for dominance in developing frontier AI models.

The evidence presented by Musk's team to prove that OpenAI violated a contract by accepting around $44 million in donations from Musk, and then planning to convert into a for-profit entity was deemed "insufficient for purposes of the high burden required for a preliminary injunction."

A judge denied Elon Musk's bid to stop Sam Altman from converting OpenAI into a for-profit, but the rivals are still set to have their day in court.

U.S. District Judge Yvonne Gonzalez Rogers denied Elon Musk’s attempt to pause OpenAI’s for-profit model but agreed to fast-track the trial later this year.

U.S. District Court Judge Yvonne Gonzalez Rogers has rejected Elon Musk’s motion for an injunction that would have blocked OpenAI’s transition into a for-profit company.

Musk does not have "the high burden required for a preliminary injunction" to block the conversion of OpenAI, said U.S. District Judge Yvonne Gonzalez Rogers in Oakland, California.

Musk had filed a motion for preliminary injunction in US District Court for the Northern District of California, claiming that OpenAI's for-profit conversation "violates the terms of Musk's donations" to the company. But Musk failed to meet the burden of proof needed for an injunction, Judge Yvonne Gonzalez Rogers ruled yesterday.

Musk, an early OpenAI backer, has been engaged in a legal showdown with the company and Altman for over a year, alleging a breach of contract and the betrayal of OpenAI's founding nonprofit mission.

A federal judge refused to give Musk an immediate injunction against OpenAI's switcheroo, but threw him a lifeline.

Elon Musk lost a court bid asking a judge to temporarily block OpenAI from turning into a for-profit business, but he also scored a win: the right to a trial.
