Judge Signals Elon Musk Fraud Suit Against OpenAI Will Reach Jury

U.S. District Judge Yvonne Gonzalez Rogers told lawyers on Jan. 7 and Jan. 8 that she intended to deny OpenAI’s motion to dismiss and that “this case is going to trial,” signaling that a jury should resolve disputed factual questions. During an occasionally testy, roughly 90-minute hearing in Oakland, the judge said there is sufficient documentary evidence to let jurors weigh credibility and timing, and she emphasized that part of the dispute will be whether jurors find witnesses credible.

Elon Musk filed the complaint in August 2024, alleging that OpenAI and certain executives misled him about the organization’s nonprofit status and that the group later adopted a for-profit structure and accrued substantial commercial value. The filing also includes unjust enrichment claims against Microsoft tied to its financial arrangements with OpenAI. The judge made clear she was likely to permit those claims to survive at least to the discovery phase, though she has not yet ruled on every aspect.

Judge Gonzalez Rogers referenced documentary evidence lodged in the case, including a 2017 diary entry by OpenAI co-founder Greg Brockman that reads, “We’ve been thinking that maybe we should just flip to a for profit. Making the money for us sounds great and all.” The judge said that language and other materials supported allowing the dispute to go to a jury, where jurors can assess whether statements and conduct amounted to actionable deception.

A central legal issue is the timing of any alleged fraud, an element with direct statutory consequences. Musk’s fraud claims are governed by a three-year statute of limitations, and the judge indicated she would allow jurors to decide when the suspected deceit began. If a jury finds key events occurred within three years of Musk’s August 2024 filing, the fraud claims would be viable; if not, those portions could be barred.

The hearing suggested high-profile testimony could be required. The judge observed the case may turn on “whether a jury believes the people who will testify and whether they are credible.” Court filings and the hearing indicated that Musk and OpenAI Chief Executive Sam Altman would likely be summoned to testify under oath if the matter reaches trial. Musk has been described as the world’s richest man with an estimated fortune near $713 billion, while Altman’s net worth has been pegged at about $2 billion.

Microsoft’s role looms large. The record notes a $1 billion investment by Microsoft in an OpenAI for-profit subsidiary in 2019 and subsequent dealings that have been characterized as creating roughly a $135 billion stake tied to the partnership. Judge Gonzalez Rogers said she had not decided whether to dismiss Musk’s unjust enrichment allegations against Microsoft.

OpenAI has been described in filings and reporting as having evolved into a commercial enterprise with an estimated valuation near $500 billion; Musk later founded xAI after parting ways with OpenAI, with a recent fundraising round valuation cited at about $230 billion. The court acknowledged the governance turmoil of 2023, when OpenAI’s board briefly fired and then reinstated Altman.

Gonzalez Rogers did not issue a signed ruling at the hearing. She said logistical details about trial structure and scheduling remain to be set, and parties should prepare for discovery and pretrial proceedings directed toward a jury trial that will probe timing, credibility and the scope of the alleged misrepresentations. The case could set consequential precedent for founders, investors and governance of research organizations that become commercial enterprises.
