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.

Verdict affects governance and ownership disputes at OpenAI, a major AI platform; it sets precedent for non-profit/for-profit splits, influences talent movement and partnerships, and reduces legal uncertainty for OpenAI's commercial operations.

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.
Jury Rejects Elon Musk Lawsuit Against OpenAI
A California jury delivered a unanimous verdict on May 18, 2026, ruling that Elon Musk’s lawsuits against Sam Altman, Greg Brockman, OpenAI and Microsoft were time-barred under the applicable statutes of limitations. Musk had alleged that OpenAI’s founders and partners improperly converted the nonprofit into a for-profit affiliate, but jurors found any alleged harms occurred before the legal deadlines for the claims. Judge Yvonne Gonzalez Rogers said there was substantial evidence supporting the jury’s finding. Musk’s lead counsel, Marc Toberoff, said the team intends to appeal. The decision removes a major potential legal threat to OpenAI — including a restructuring that Musk sought — ahead of the company’s reported plans for an initial public offering.
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.
