Elon Musk and Sam Altman Set for OpenAI Lawsuit Trial

A U.S. jury found OpenAI and Sam Altman not liable in Elon Musk’s case, while additional claims that OpenAI abandoned its charitable mission were dismissed as filed too late.

Fact Check
The claim that Elon Musk and Sam Altman were set for an OpenAI lawsuit trial is confirmed by multiple high-authority sources including NPR, CNBC, and the New York Times. The trial began April 27, 2026, in the US District Court for the Northern District of California, as reported by Cryptobriefing and NPR. The claim's framing as 'set for trial' is slightly behind events - by May 18, 2026 (the event_time), the trial had already concluded with a verdict, as reported by Cryptobriefing's verdict article. The claim's description of the case potentially reshaping 'how nonprofit commitments are treated in technology companies' and affecting 'AI industry structures and investor confidence' is consistent with NPR's reporting that up to $150 billion in damages and potential unwinding of OpenAI's for-profit structure were at stake. The only minor inaccuracy is the 'set for' framing, as the trial was already underway and concluded on May 18, 2026.
Summary

A U.S. jury in Oakland, California, rejected Elon Musk’s claims against OpenAI, Sam Altman, Greg Brockman, and Microsoft after a three-week trial, and U.S. District Judge Yvonne Gonzalez Rogers agreed with the advisory jury’s conclusion that neither OpenAI nor Altman was liable. The judge also dismissed Musk’s breach of charitable trust and unjust enrichment claims on statute-of-limitations grounds, finding they were brought too late. Musk, who co-founded OpenAI in 2015 and left its board in 2018, had argued that the organization was founded as a charitable AI lab and later improperly shifted toward a for-profit model under Altman. He said he contributed about $38 million and sought remedies including up to $134 billion in forfeited gains, removal of Altman and Brockman from leadership, and reversal of a 2025 restructuring. OpenAI argued Musk’s donations had no legally binding written restrictions and that restructuring was necessary to fund the high cost of advanced AI development. Musk’s lawyer said he still has the right to appeal.
