Musk Testimony Dominated First Week of Musk v. Altman
The first week of the Musk v. Altman trial in Oakland concluded May 2, 2026, after Elon Musk testified for three days, telling the jury OpenAI leaders tried to "steal a charity." Musk sued OpenAI, CEO Sam Altman and President Greg Brockman in 2024, alleging they reneged on promises to keep OpenAI a nonprofit and misused about $38 million Musk donated. OpenAI, which has raised large private capital and counts Microsoft among investors, calls the claims baseless. Musk’s legal team seeks up to $134 billion in damages and wants remedies including reversing OpenAI’s for-profit conversion and removing Altman and Brockman. Judge Yvonne Gonzalez Rogers is presiding; the trial was split into a liability phase expected to conclude by May 21, 2026.
A high-profile legal challenge involving OpenAI, its founders and major investors (including Microsoft) could materially affect governance, corporate structure, investor returns and the broader AI industry; potential large damages and remedy requests make this a consequential event.
