Musk vs. OpenAI Trial: Jury Selection Set for April 27 as CEO Ouster Bid Escalates

Elon Musk escalated his long-running lawsuit against OpenAI during the week of April 7-11, 2026, seeking not only damages but the explicit ouster of CEO Sam Altman and President Greg Brockman. Jury selection for the trial is scheduled to begin April 27 in federal court in Oakland, California. The case, which Bloomberg estimated involves claims exceeding $100 billion, centers on Musk's allegation that OpenAI's conversion from a nonprofit to a for-profit structure violated the founding agreements he signed when he helped establish and fund the organization in 2015.

The week's proceedings turned combative after OpenAI publicly accused Musk of staging an "ambush" — filing aggressive last-minute motions the company characterized as bad-faith litigation tactics designed to disrupt its IPO preparations and destabilize its leadership. OpenAI's legal team argued that Musk's ouster demands are legally unprecedented and have no basis in corporate or contract law. Musk's team countered that Altman and Brockman's stewardship of OpenAI has systematically betrayed its founding mission of developing AI for the benefit of humanity rather than maximizing shareholder returns.

The trial arrives at a delicate moment for OpenAI. With an IPO in preparation and a $852 billion valuation on the line, prolonged courtroom uncertainty poses real risks to investor sentiment and employee retention. Legal analysts note that the ouster claims face a high bar — courts rarely intervene in corporate leadership decisions unless fraud or clear contractual breach is proven. But the lawsuit's sheer scale and the reputational stakes for both Musk and Altman have made it one of the most watched technology legal battles in years, with implications that extend well beyond the two principals to the broader question of how AI's most powerful institutions are governed.
