What the Jury Will Decide in Musk vs. Altman
Nine California jurors are deliberating in Elon Musk's lawsuit against OpenAI, its cofounders and Microsoft after closing arguments concluded in federal court in Oakland on May 14, 2026. The jury's verdict is advisory; U.S. District Judge Yvonne Gonzalez Rogers will make the final liability determination. The case, filed in 2024, alleges breach of charitable trust and unjust enrichment tied to OpenAI's 2025 for‑profit recapitalization and donations Musk says were misused. The trial moves into a remedies phase beginning the same week, where Gonzalez Rogers will hear arguments on damages and potential relief if liability is found. Musk has sought a range of remedies including removal of OpenAI executives and return of alleged “ill-gotten gains”; his lawyers previously sought up to $134 billion in damages. Defendants named include OpenAI, CEO Sam Altman, Greg Brockman and Microsoft.
The trial concerns OpenAI — a foundational AI company — and could force structural remedies affecting its for‑profit affiliate, set legal precedent about donor restrictions and nonprofit-to-for-profit transitions, and influence major commercial partners such as Microsoft.

Jury Rejects Musk’s Lawsuit Against OpenAI
A U.S. jury in Oakland on 2026-05-18 unanimously dismissed Elon Musk's lawsuit against OpenAI and its leaders as time‑barred after under two hours of deliberation. Musk had alleged that OpenAI’s leadership, including CEO Sam Altman and board chair Greg Brockman, converted the nonprofit into a profit-seeking enterprise and accused them of enriching investors; he also claimed he was manipulated into donating $38 million. Judge Yvonne Gonzalez Rogers said there was ample evidence supporting the jury's finding and noted the statute-of-limitations issue, and Musk's team reserved the right to appeal. The ruling removes a major legal threat as OpenAI prepares for a potential IPO (reports suggested a possible $1 trillion valuation) and follows large investments from Microsoft, which a Microsoft manager said has committed more than $100 billion to the partnership. The decision is consequential for governance and fundraising timelines across the AI sector.
Musk Testimony Dominated First Week of Musk v. Altman
The first week of the Musk v. Altman trial in Oakland concluded May 2, 2026, after Elon Musk testified for three days, telling the jury OpenAI leaders tried to "steal a charity." Musk sued OpenAI, CEO Sam Altman and President Greg Brockman in 2024, alleging they reneged on promises to keep OpenAI a nonprofit and misused about $38 million Musk donated. OpenAI, which has raised large private capital and counts Microsoft among investors, calls the claims baseless. Musk’s legal team seeks up to $134 billion in damages and wants remedies including reversing OpenAI’s for-profit conversion and removing Altman and Brockman. Judge Yvonne Gonzalez Rogers is presiding; the trial was split into a liability phase expected to conclude by May 21, 2026.
Jury Rejects Musk's OpenAI Lawsuit; Trial Revealed Similar Aims
A jury rejected Elon Musk's lawsuit against other founders of OpenAI and Microsoft, with the trial revealing evidence that weakened Musk's claims — in part because he waited years to file. Plaintiffs argued that Sam Altman and Greg Brockman breached a charitable trust and were unjustly enriched; defense attorneys countered point-by-point that the law and evidence favored OpenAI. Court testimony showed Musk asked Brockman in 2017 to send OpenAI researchers to assist Tesla's autopilot team (work that was not reimbursed), and highlighted Musk's attempts to secure sole control of an OpenAI for-profit affiliate. Musk posted a later-deleted criticism of the judge and said he would appeal. Legal scholars noted Musk himself redirected resources in ways potentially inconsistent with his charitable claims.
