After less than two hours of deliberations, a jury on Monday rejected Elon Musk's claims against OpenAI CEO Sam Altman, ending a dramatic chapter in the bitter rivalry between the two tech billionaires, who were once close friends.

The court, led by U.S. District Judge Yvonne Gonzalez Rogers, agreed with the advisory jury's determination that Altman and OpenAI were not liable, and that Musk's "claims of breach of charitable trust and unjust enrichment are dismissed as untimely."
