Resolution criteria
The jury trial is scheduled for April 27, 2026, in Oakland, California. The market resolves YES if Musk prevails on any material claim in the lawsuit (breach of contract, fraud, breach of fiduciary duty, or unjust enrichment). The market resolves NO if OpenAI and its defendants prevail on all material claims or if the case is dismissed. Resolution will be determined by the jury verdict and any subsequent appeals that reach final judgment.
For resolution purposes, "winning" means obtaining a judgment in Musk's favor on at least one substantive claim that results in meaningful damages or injunctive relief. Dismissals on procedural grounds or settlements that do not constitute a material victory for Musk resolve as NO.
Background
Musk sued OpenAI and its co-founders Sam Altman and Greg Brockman in 2024, alleging they betrayed their original contractual agreements by pursuing profits instead of the nonprofit's founding mission to develop AI that benefits humanity. Musk's attorneys argue that he is owed the "wrongful gains" derived by OpenAI and Microsoft from his early contributions, which could amount to $134.5 billion.
Musk was an influential co-founder of OpenAI in 2015 and provided early financial backing to what was then—and Musk believes should still be—a nonprofit focused on the responsible development of AI. In his lawsuit, Musk alleged that OpenAI abandoned this original purpose, that he had contributed funding as well as his "prestige and reputation" in the understanding this purpose would be maintained, and that OpenAI's leadership had since his departure transformed the company into a "get-rich-quick scheme, selling out the nonprofit for personal gain".
OpenAI said in a letter to investors that it has "strong defenses" and feels confident about its chances of winning the case. OpenAI stated it believes the case is worth no more than the $38 million that Musk donated.
Considerations
The judge found "ample evidence" supporting Musk's claims, pointing directly to Brockman's diary entries and internal communications showing OpenAI's leadership saying one thing publicly and planning something completely different privately. However, the question is whether a jury believes that what happened at OpenAI was legitimate business evolution or deliberate deception. The case hinges on credibility and interpretation of early communications rather than clear-cut documentary evidence, making the outcome genuinely uncertain despite the judge's preliminary findings.
