A federal judge has appointed a mediator to help resolve the dispute between Musk’s xAI and Altman’s OpenAI. A trial ran from April to May 2026 in the US District Court for the Northern District of California, presided over by Judge Yvonne Gonzalez Rogers. The advisory jury came back with a unanimous finding that Musk’s core claims were barred by the statute of limitations, leading to a dismissal of the main case on May 18, 2026. Musk filed the original lawsuit, formally titled Musk v. Altman, in February 2024, alleging OpenAI violated its founding 2015 nonprofit charter by transforming into a for-profit entity. He sought up to $150 billion in damages. The jury determined Musk waited too long, meaning the substance of the case never received a ruling on the merits. A separate trade secrets lawsuit by Musk’s xAI against OpenAI, alleging theft of proprietary information related to Grok, was dismissed with prejudice on June 15, 2026.
