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.
High-profile legal proceedings involving OpenAI and its CEO raise questions of trust, transparency and potential regulatory or partner fallout for the AI industry; outcomes could affect public and policymaker confidence in major AI labs.

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.
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.
Musk vs OpenAI Trial Reveals Control and Donation Dispute
During the second week of the Elon Musk v. OpenAI trial, OpenAI president Greg Brockman testified that Musk pushed the company to create a for‑profit arm and sought “absolute control” over it. Musk previously testified that OpenAI CEO Sam Altman and Brockman deceived him into donating $38 million by promising to keep the organization nonprofit; OpenAI later accepted large investments from Microsoft and restructured to operate a for‑profit subsidiary. The court proceedings have included testimony, diary excerpts and other witness accounts; the trial is occurring as OpenAI plans a public listing.
