Elon Musk's $134 billion lawsuit against OpenAI, Sam Altman, and Greg Brockman is scheduled to begin with jury selection April 27 before U.S. District Judge Yvonne Gonzalez Rogers in Oakland, with four weeks set aside. Four claims survive from Musk's original 26: unjust enrichment, fraud, constructive fraud, and breach of charitable trust — centering on whether OpenAI's transition from nonprofit to for-profit violated commitments made when Musk donated $38M in seed funding. OpenAI has called the suit a "harassment campaign driven by ego and jealousy"; the trial is expected to surface internal communications about the company's founding promises.
