On August 5, 2024, Elon Musk filed a civil complaint in the U.S. District Court for the Northern District of California against OpenAI, Inc., Sam Altman, Greg Brockman, Microsoft Corporation, and several affiliated entities.
The case, captioned Musk v. Altman, et al., No. 4:24-cv-04722, was assigned to U.S. District Judge Yvonne Gonzalez Rogers in the Oakland Division. An earlier version had been filed in San Francisco Superior Court in February 2024 and voluntarily dismissed before the federal refiling.
The operative complaint alleges that OpenAI departed from the charitable mission stated when the entity was formed in 2015. The complaint asserts claims for breach of charitable trust, constructive fraud, fraud, and unjust enrichment against the OpenAI defendants, and aiding and abetting breach of fiduciary duty against Microsoft. Trial began with jury selection on April 27, 2026 in Oakland and is expected to run several weeks.
LEGAL DISCLAIMER: All allegations referenced in this article are drawn from publicly filed pleadings and court orders. The defendants deny the allegations and the matter is being tried on the merits. This article provides general informational content regarding civil procedure, charitable trust law, and fiduciary duty principles.

The Three Procedural Phases of Federal Civil Litigation
Every federal civil case proceeds through three distinct phases, each governed by the Federal Rules of Civil Procedure. Understanding these phases is essential to understanding what the Musk v. Altman trial will and will not decide.
Phase One: Pleadings and the
Motion to Dismiss
In phase one, a defendant may move to dismiss under Federal Rule of Civil Procedure 12(b)(6) for failure to state a claim. The court accepts the well-pleaded facts as true and asks whether they would entitle the plaintiff to relief if proven.
In March 2025, Judge Gonzalez Rogers dismissed the breach of contract claim, ruling that the plaintiff had not pleaded a sufficient written contract barring restructuring. Other claims, including charitable trust, fraud, and unjust enrichment, survived and proceeded to discovery.
Phase Two: Discovery and
Summary Judgment
After document exchange and depositions, either side may move for summary judgment under Federal Rule of Civil Procedure 56, which requires the court to grant judgment when there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.
On January 7, 2026, Judge Gonzalez Rogers denied summary judgment on the surviving OpenAI claims and on aiding and abetting against Microsoft, while dismissing tortious interference and unjust enrichment as to Microsoft. The court also issued statute-of-limitations rulings that narrowed the timeframe of recoverable conduct.
Phase Three: Trial on the Merits
When summary judgment is denied, the case proceeds to trial.
A nine-person jury was empaneled on April 27, 2026 to hear the remaining claims.
As certain claims are equitable in nature, the jury serves in an advisory capacity under Federal Rule of Civil Procedure 39(c), with the court retaining authority to make the ultimate findings on those claims.
The Charitable Trust Doctrine in California
California treats nonprofit assets and donor contributions as held in trust for the charitable purposes for which they were given. Standing to enforce a charitable trust is governed by California Corporations Code Section 5142, which authorizes the Attorney General and certain interested persons to bring a breach action. California Business and Professions Code Section 17510.8 separately requires that funds solicited for a represented charitable purpose be used for that purpose. These statutes form the legal backbone of the charitable trust and constructive fraud counts proceeding to trial.
Recent federal litigation involving technology companies and emerging platforms reflects a growing willingness by courts to examine whether corporate missions, public representations, and platform governance structures can give rise to enforceable legal obligations beyond traditional contract principles.
See, e.g., Musk v. Altman, No. 4:24-cv-04722-YGR (N.D. Cal. 2026) (challenging deviation from nonprofit mission and governance structure); In re Facebook, Inc. Consumer Privacy User Profile Litig., 402 F. Supp. 3d 767 (N.D. Cal. 2019) (allowing claims based on public-facing representations to users).
In litigation involving cryptocurrency exchanges and fintech platforms, plaintiffs have increasingly asserted claims sounding in fraud, unjust enrichment, and breach of fiduciary duty where formal agreements are ambiguous or incomplete.
See, e.g., SEC v. Terraform Labs Pte. Ltd., 2023 WL 4858299 (S.D.N.Y. July 31, 2023) (allowing fraud-based claims arising from representations to investors in a crypto ecosystem); In re Celsius Network LLC, 647 B.R. 631 (Bankr. S.D.N.Y. 2023) (addressing rights and obligations in the absence of traditional custodial agreements).
What Florida Founders, Donors, and Investors Should Take Away
The case is being tried under California law, but the underlying principles travel.
Florida nonprofits, technology startups, and digital asset ventures operate under analogous fiduciary duty and corporate governance frameworks. Founders who solicit contributions on a stated mission, directors who later restructure the entity, and donors who give in reliance on representations should each understand how those obligations are documented and how they survive corporate change.
The same care applies to AI law, blockchain law, and the digital asset estate planning context where mission, control, and restitution are increasingly contested.
How the Verdict Could Reshape Nonprofit AI Governance
The questions before the court reach beyond the parties. Whether nonprofit governance survives a transition to a for-profit subsidiary, whether donors hold enforceable trust interests, and whether third-party investors can be liable for aiding and abetting fiduciary breach will inform how courts evaluate AI labs, public benefit corporations, and digital asset platforms going forward.
The Goliath Ventures Chapter 11 proceeding raises related questions in the cryptocurrency context, where founders, investors, and creditors face overlapping civil, bankruptcy, and criminal tracks.
