Elon Musk takes the stand in high-profile trial against OpenAI

Elon Musk began testifying in his California federal jury trial against OpenAI.

He alleges OpenAI abandoned its nonprofit founding mission and breached a charitable trust.

The lawsuit includes claims of fraud and unjust enrichment, and names Sam Altman, Greg Brockman, and Microsoft as defendants or related parties.

The case could shape OpenAI’s corporate structure, leadership, and the legal limits of AI governance.
