A US court has thrown out Elon Musk's lawsuit against OpenAI and its top executives, Sam Altman and Greg Brockman, after a jury found he waited too long to file the case.
The nine-person jury deliberated for less than two hours following a three-week trial. Judge Yvonne Gonzalez Rogers accepted the verdict as the court's own, dismissing Musk's claims of breach of charitable trust and unjust enrichment.
Musk, an early investor, alleged Altman misled him by transforming OpenAI from a nonprofit into a for-profit enterprise now valued at nearly $1 trillion. However, OpenAI argued there was never a promise to keep the company nonprofit forever.
Outside the court, OpenAI lawyer William Savitt told reporters the jury determined the lawsuit was an after-the-fact contrivance aimed at sabotaging a competitor.
Musk posted on X that he would file an appeal, calling the ruling a "calendar technicality." His lawyer, Steven Molo, compared the loss to historic American defeats, vowing the feud is far from over.
The trial revealed deep tensions between the two Silicon Valley titans, with Altman testifying that Musk's attempt to gain control over OpenAI contradicted its core mission. Altman described the public attacks as "extremely painful."
