Musk vs OpenAI Trial Enters Second Week
Musk says OpenAI used $38 million in donations to build a $850 billion business, and he wants leaders removed and the conversion undone.
On Thursday, April 30, 2026, Elon Musk concluded three days of testimony in his federal lawsuit against OpenAI CEO Sam Altman and President Greg Brockman, alleging they abandoned the organization's nonprofit mission.
Musk claims he provided $38 million in seed funding for a nonprofit to serve as a "counterweight" to Google, alleging Altman and Brockman orchestrated a "bait and switch" to create a for-profit entity.
During intense cross-examination, Musk clashed with OpenAI lead counsel William Savitt, accusing him of asking misleading questions "designed to trick" him while downplaying his competing company xAI's reliance on OpenAI technology.
Musk's attorneys are seeking up to $134 billion in damages, with Judge Yvonne Gonzalez Rogers set to make the final decision after a jury provides an advisory verdict on liability.
Proceedings resume next week with further testimony expected from Altman and Brockman, while Musk's family office manager Jared Birchall has already testified regarding the disputed $38 million donations.
