TL;DR

On May 18, 2026, a federal jury in Oakland dismissed Elon Musk’s lawsuit against Sam Altman, Greg Brockman, OpenAI, and Microsoft, citing the statute of limitations as the reason for dismissal. The case, which challenged OpenAI’s restructuring and alleged misuse of charitable assets, was ended before the court examined the substantive claims.
The jury’s decision was based solely on the timing of Musk’s filing, which was found to be outside the three-year statute of limitations for the claims he raised. The court did not evaluate whether OpenAI’s conversion from a nonprofit to a for-profit entity violated charitable trust laws or whether the restructuring transferred assets improperly, as these issues were not addressed in the ruling.
U.S. District Judge Yvonne Gonzalez Rogers confirmed the verdict, emphasizing that the case was dismissed on procedural grounds, not on the merits of the allegations. Musk’s legal team has announced an appeal, which aims to challenge the statute of limitations ruling and revisit the substantive issues.

deliberation · statute-of-limitations
upper bound · disgorgement-eligible
$852B-$1T valuation · ~$60B raise
Foundation coalition flagged · April 2025
- Musk filed too late · 2024 filing fell outside the three-year statute of limitations under California Code of Civil Procedure
- The defense’s “harm occurred no later than 2021” timing argument was sufficient
- Discovery-rule tolling rejected — Musk’s argument that asset-transfer magnitude was not knowable in time did not extend the window
- “Fraudulent concealment” tolling rejected — no separate basis to delay the clock
- Microsoft aiding-and-abetting claim dismissed by virtue of the predicate claim being dismissed
- Whether Altman and Brockman violated a charitable trust · not addressed on the merits
- Whether the 2019 for-profit subsidiary structure improperly transferred nonprofit assets · not addressed
- Whether the October 2025 PBC conversion at ~$500B is a legally permissible disposition of charitable assets · not addressed
- Whether the Microsoft AGI-voids-the-deal clause is consistent with the original nonprofit mission · not addressed
- Whether Microsoft’s $13B 2019-2023 investment trajectory aided and abetted any breach of charitable trust · not addressed on its own merits

Implications for OpenAI’s IPO and Legal Challenges
The dismissal clears a significant legal obstacle for OpenAI’s planned IPO, which aims for a valuation between $852 billion and $1 trillion. By removing this lawsuit as a potential disruption, the ruling allows OpenAI to proceed with its public offering. However, the case’s core legal questions about the legality of converting a charitable trust into a for-profit entity under California law remain unresolved and could resurface in future litigation or regulatory review.
This outcome underscores the importance of procedural timing in high-stakes corporate and nonprofit restructuring cases and highlights ongoing legal scrutiny of AI industry practices concerning charitable assets and corporate governance.

Background on OpenAI’s Restructuring and Legal Scrutiny
OpenAI was founded as a nonprofit with a mission to develop artificial general intelligence safely. In 2021, it transitioned into a for-profit entity, claiming this move was necessary to attract investment and scale its research. Musk and others have questioned whether this restructuring violated California charitable trust laws, which require assets held for charitable purposes to remain dedicated to those aims.
Legal challenges have been mounting since late 2024, including investigations by the California Attorney General and petitions from foundations. The case in question was the most high-profile attempt to challenge the legitimacy of OpenAI’s conversion, focusing on whether the transfer of assets and intellectual property was lawful under nonprofit statutes.

Unresolved Legal and Regulatory Questions
It remains unclear whether the underlying legal theory—that converting a charitable trust into a for-profit violates California law—can be successfully litigated in the future, or if it is effectively settled by this procedural dismissal. The California Attorney General’s ongoing investigation and other potential plaintiffs have not been resolved and could lead to new legal challenges.
