April 24 (Reuters) – A U.S. judge on Friday dismissed Elon Musk’s fraud claims in ‌his lawsuit accusing OpenAI and co-founder ‌Sam Altman of betraying OpenAI’s original mission, but plans ​to proceed to trial on Musk’s breach of charitable trust and unjust enrichment claims.

The ruling was issued by U.S. District Judge Yvonne Gonzalez ‌Rogers in Oakland, ⁠California.

Jury selection is scheduled to begin on Monday, and opening arguments are ⁠expected on Tuesday.

Musk had said dismissing his fraud and constructive fraud claims, which he proposed, ​would streamline ​the case and ​keep jurors focused on ‌his goal of ensuring that OpenAI benefit humanity rather than be a “wealth machine.”

The case centers on Musk’s claim that OpenAI, Altman and Microsoft, one of OpenAI’s largest investors, conned him and the public by ‌forming a for-profit entity in ​2019, after he left OpenAI’s ​board.

OpenAI is ​preparing for a potential initial public ‌offering that could value it ​at $1 trillion, ​Reuters has reported.

Musk is seeking $150 billion in damages, according to a person involved in ​the case, ‌with proceeds going to OpenAI’s charitable arm.
