Court Examines Sam Altman's Credibility in OpenAI Trial
Sam Altman, CEO of OpenAI, testified under oath in a California federal court as part of a lawsuit brought in part by Elon Musk challenging OpenAI’s for‑profit structure. Plaintiffs' attorney Steve Molo pressed Altman over whether he disclosed economic ties to OpenAI via an LP stake in a Y Combinator fund during his May 2023 Senate testimony. The trial revisited OpenAI’s 2023 board firing episode — when Altman and Greg Brockman were briefly removed — and centers on whether the nonprofit board truly controls the for‑profit entity. Witnesses cited by both sides include former board members Helen Toner and Tasha McCauley, OpenAI cofounder Ilya Sutskever, Bret Taylor, Dr. Zeko Kolter, and Microsoft CEO Satya Nadella. The jury and Judge Yvonne Gonzalez Rogers are weighing Altman’s credibility as a central fact in the case.
The trial involves the CEO of a major AI lab (OpenAI) and questions about governance, disclosure and control of foundational AI models—issues that can influence regulatory scrutiny, corporate governance norms, and public trust in AI across the industry.

Sam Altman to Testify in Musk’s OpenAI Lawsuit
Sam Altman, CEO of OpenAI, is scheduled to testify in a federal trial in Oakland, California on May 12, 2026, in Elon Musk’s lawsuit alleging OpenAI broke commitments to remain a nonprofit. Bret Taylor, OpenAI’s board chair, continued testimony about the board’s role and the company’s corporate recapitalization; he will resume the stand the following morning. Microsoft CEO Satya Nadella also testified, noting Microsoft’s more-than-$13 billion investment in OpenAI and saying Musk did not raise concerns with him about violations. Musk’s 2024 suit names OpenAI, Altman and President Greg Brockman and alleges roughly $38 million in donations were used for unauthorized commercial purposes. The trial began late April/early May 2026 and has included testimony from multiple senior executives.
Musk v. Altman: High‑Profile OpenAI Lawsuit Continues
Elon Musk spent roughly three days on the witness stand this week in his lawsuit against OpenAI, where he alleges that Sam Altman betrayed OpenAI’s original nonprofit mission by converting the organisation to a for‑profit model. During testimony, emails, texts and Musk’s tweets have been introduced as evidence. TechCrunch’s Equity podcast (video) covered the courtroom developments, noted more witnesses remain to testify, and discussed related topics including Big Tech earnings and the limits of the current AI spending cycle. The piece was published by TechCrunch on May 1, 2026.
Trust at Center of Musk–OpenAI Trial
A high‑profile civil trial in Oakland has put the collapse of Elon Musk and Sam Altman’s early partnership under public scrutiny. Musk sued OpenAI and Altman in 2024 alleging the lab abandoned commitments to remain a nonprofit after creating a for‑profit affiliate; closing arguments concluded in mid‑May 2026 and jurors began deliberations. The article traces the relationship from the 2015 founding of OpenAI (initially pitched as a nonprofit counterweight to Google) through tensions over control, fundraising and talent poaching, Musk’s departure from the board in 2018, Microsoft’s $10 billion investment in OpenAI in 2023, and Musk’s creation and February 2026 merger of xAI with SpaceX. The trial features testimony from Musk, Altman and other co‑founders and centers on claims of breach of charitable trust, unjust enrichment and competing narratives about who founded and funded OpenAI.
