Musk v. Altman et al. (No. 4:24-cv-04722-YGR, N.D. Cal.) includes claims that continued after the May 2026 trial. Judge Yvonne Gonzalez Rogers adopted the advisory jury’s finding that Musk’s trial claims were time-barred, but subsequently issued orders addressing remaining claims and mediation. The May trial outcome should not be described as dismissal of the entire litigation.

Trial disposition

On April 24, the court deemed Musk’s fraud and constructive-fraud claims voluntarily dismissed with prejudice, while stating that breach-of-charitable-trust and unjust-enrichment claims would proceed to trial.

In her May 20 order, Judge Gonzalez Rogers adopted the advisory jury’s verdict and her statements at trial as findings of fact and conclusions of law under Federal Rule of Civil Procedure 52(a). The order addresses the timeliness of the claims tried; it does not dispose of every remaining cause of action.

Remaining litigation

• On June 10, the court noted that the plaintiffs had chosen not to amend their remaining causes of action and directed the parties to meet and confer on a proposed schedule. The judge expressed concerns about the claims’ viability while finding the existing briefing insufficient to decide them.
• On July 1, the court appointed R. David Proctor as mediator for all claims and defenses, including antitrust claims and claims not reduced to final judgment. The order provides for a special-master role if mediation is unsuccessful; it does not announce a settlement.
• On August 10, Musk and X.AI Corp. filed an answer to OpenAI’s amended counterclaims under California’s Unfair Competition Law and for tortious interference with prospective economic advantage.

These are dated procedural records, not a representation that the public materials establish every subsequent filing or outcome.
