Musk v. Altman trial over OpenAI begins
A long-running lawsuit filed by Elon Musk against OpenAI CEO Sam Altman and OpenAI president Greg Brockman goes to trial in federal court in Oakland beginning the week of April 24, 2026. Musk alleges OpenAI reneged on promises to keep the lab nonprofit and seeks remedies including unwinding OpenAI’s for-profit conversion, removal of executives, and up to $134 billion in damages; Microsoft is also named as a defendant. The claims have been narrowed to four causes of action. Judge Yvonne Gonzalez Rogers will preside; the court divided the proceedings into a liability phase and a remedies phase, with liability expected to run into mid-May and an advisory jury. The case coincides with major corporate events for both sides, including OpenAI’s potential IPO and Musk’s xAI–SpaceX merger activity.
Musk vs Altman: OpenAI Dispute Moves to Court
Elon Musk has taken his long-running allegation of fraud against OpenAI and CEO Sam Altman to trial. According to reporting cited by t3n, jury selection begins the week of April 27, 2026, and the trial is expected to last two to three weeks. Musk argues that OpenAI’s 2025 restructuring — which created a for‑profit core while retaining oversight by the original nonprofit — violated the founders’ agreement; he seeks Altman’s removal and more than $134 billion in damages to be redirected to OpenAI’s nonprofit arm. OpenAI denies the claims, published internal communications it says show Musk knew of the plans, and characterizes the suit as motivated by jealousy. The case could expose private depositions and documents publicly and has implications for OpenAI’s planned IPO and corporate governance of major AI labs.
Elon Musk Accuses Sam Altman of 'Plundering' OpenAI
At the opening of a civil trial in Oakland on April 29, 2026, Elon Musk accused OpenAI’s leadership—specifically CEO Sam Altman and board chair Greg Brockman—of converting OpenAI away from its original non‑profit mission for personal gain and demanded the company be returned to non‑profit status. Musk’s filing alleges he was misled about how his earlier donations would be used and reportedly seeks $150 billion in damages. The suit also names Microsoft; Microsoft denies any prior collusion with OpenAI and its CEO Satya Nadella is expected to testify. The article notes OpenAI’s corporate evolution (2015 non‑profit founding, later creation of OpenAI LP, and more recently conversion of OpenAI LP into a Public Benefit Corporation) and that judges cautioned Musk to curb public commentary about the case. The dispute comes as OpenAI pursues an IPO and Musk’s xAI competes in the AI market.
