A federal jury ruled Elon Musk's OpenAI lawsuit untimely, dismissing all claims without reaching the merits. Musk vows a Ninth Circuit appeal.
A federal jury in Oakland ruled May 18 that Elon Musk filed his lawsuit against OpenAI, its executives, and Microsoft too late, finding all claims barred by the applicable statute of limitations [1]. The jury returned the advisory verdict in under two hours [1]. Judge Yvonne Gonzalez Rogers immediately adopted the finding and dismissed all claims [1][2].
The case, filed in the Northern District of California, named OpenAI, CEO Sam Altman, co-founder Greg Brockman, and Microsoft as defendants [1][2]. Musk, who co-founded OpenAI in 2015 before departing its board, alleged that the organization and its principals breached fiduciary duties and betrayed a founding commitment to operate as a nonprofit in the public interest [2]. The jury never reached those underlying allegations. Instead, it found that Musk had sufficient notice of the facts underlying his claims well before he initiated litigation, placing his complaint outside the limitations window [1][2].
The procedural posture matters. Because the dismissal rests entirely on timeliness, the Ninth Circuit on appeal will face a threshold question, whether the limitations clock ran, before it can address the substantive disputes Musk raised [1]. Those disputes, including whether a founder's charitable-mission commitment is legally enforceable against a converted or restructuring entity, remain unresolved on the merits [2]. A ruling in Musk's favor on limitations at the appellate level would return the case to the district court for a merits trial, potentially drawing in Microsoft's deep financial involvement with OpenAI and the company's ongoing conversion from nonprofit to for-profit structure [1][2]. Musk's own AI venture, xAI, competes directly with OpenAI, a fact defendants highlighted throughout trial as evidence of a commercial rather than altruistic motive behind the lawsuit [1].
Musk announced he would appeal, characterizing the verdict as a ruling on a procedural calendar matter rather than the substance of his allegations [1]. His legal team has not yet filed a notice of appeal. The Ninth Circuit, which has shown willingness to scrutinize limitations rulings in complex commercial cases, will set the next schedule once that filing is made [2].
