A jury in Oakland, California, handed a decisive legal victory to OpenAI and CEO Sam Altman on Monday, May 19, 2026, dismissing Elon Musk's $150 billion lawsuit on procedural grounds rather than the substance of his claims. The nine-member jury unanimously found that the statute of limitations had expired before Musk filed his lawsuit in 2024, meaning he waited too long to bring his claims under applicable legal deadlines. The ruling removes a major legal threat for OpenAI at a pivotal moment, but it also leaves the most explosive question at the heart of the case unanswered: whether OpenAI actually betrayed the nonprofit mission on which it was founded in 2015.

What Was Musk Actually Suing OpenAI Over?

Musk cofounded OpenAI in 2015 alongside Sam Altman, Greg Brockman, and other researchers at a time when concerns were growing about how artificial intelligence could reshape society. The original vision was straightforward: the company would focus on building safe AI systems that benefitted humanity rather than prioritizing shareholder returns. Musk claims he contributed roughly $38 million to OpenAI during its early years, but relations between the founders deteriorated sharply after the company created a for-profit subsidiary and Microsoft invested heavily in the organization.

Musk's core accusation was that Altman and Brockman enriched themselves by transforming OpenAI from a nonprofit charity into a for-profit entity. Shortly after the verdict, Musk repeated his accusations on X, stating: "Altman & Brockman did in fact enrich themselves by stealing a charity. The only question is WHEN they did it!" He also warned that "Creating a precedent to loot charities is incredibly destructive to charitable giving in America." Musk has decided to appeal, ensuring that the increasingly bitter feud between two of Silicon Valley's most powerful figures is unlikely to end any time soon.

Why Did the Jury Rule Against Musk if the Core Question Remains Unanswered?

The trial centered on a relatively technical legal question: when did Musk become aware that OpenAI was moving toward a profit-driven structure? Because the lawsuit was filed in 2024, Musk needed to convince jurors that the alleged wrongdoing occurred within the legal time limit for bringing his claims. After deliberating for less than two hours, the jury sided with OpenAI's argument that Musk could have filed his lawsuit much earlier and therefore waited too long.

Evidence presented during the trial showed that discussions about creating a for-profit arm dated back to at least 2017. Jurors also heard testimony that Altman had sent Musk documents in 2018 outlining plans for OpenAI to raise billions of dollars through a for-profit structure. Musk argued that his concerns fully crystallized only in 2023, particularly after Microsoft's substantial investments into OpenAI's for-profit arm. However, OpenAI's lawyers argued that Musk had known for years that the company planned to pursue a commercial structure and raise enormous amounts of outside funding.

How Did Musk's Rivalry with OpenAI Lead to xAI and Grok?

The relationship between Musk and Altman deteriorated significantly after Musk resigned from OpenAI's board in February 2018, officially citing potential conflicts of interest as Tesla became more focused on artificial intelligence. The split deepened after OpenAI created a for-profit subsidiary and Microsoft invested heavily in the company. Microsoft has since committed tens of billions of dollars to its partnership with OpenAI, helping transform ChatGPT into one of the defining products of the global artificial intelligence boom.

Musk became increasingly critical of the company, arguing that OpenAI had moved far beyond the nonprofit vision on which it was founded. In 2023, he launched a rival artificial intelligence company called xAI, the maker of the Grok chatbot, before filing his lawsuit against OpenAI the following year. OpenAI's lawyers portrayed Musk's lawsuit as partly motivated by rivalry, arguing that Musk became hostile only after losing influence within the company and watching Altman turn OpenAI into the dominant force in generative artificial intelligence.

What Questions Did the Verdict Leave Unanswered?

Because the case was resolved on procedural grounds, the court did not answer some of the biggest questions raised by the artificial intelligence boom. The verdict left unresolved critical issues including:

• Governance and Regulation: How these increasingly powerful artificial intelligence systems should be governed and what oversight mechanisms are necessary as they become more capable.
• Economic Benefit Distribution: Who should benefit economically from artificial intelligence development and whether profits should be shared more broadly with society.
• Public Interest Claims: Whether companies developing increasingly powerful artificial intelligence tools can still claim to act in the public interest while pursuing enormous commercial growth and shareholder returns.
• Data Extraction and Consent: How artificial intelligence companies should handle transparency, labor practices, and the extraction of data used to train artificial intelligence systems without explicit user consent.

Nicole Turner Lee, director of the Centre for Technology Innovation, highlighted one of the central problems surrounding artificial intelligence development. She explained that the technology is deeply "extractive," noting that "It does undergo theft where people do not consent as to whether or not their information, their image, their voice, their text are actually being extracted." Turner Lee raised concerns about compensation and consent in artificial intelligence training systems, issues that remained largely outside the scope of the trial due to it ultimately centering on procedural issues.

The ruling also removed the possibility of a far more disruptive outcome that could have threatened OpenAI's corporate structure, its partnership with Microsoft, and the wider wave of investment pouring into the artificial intelligence industry. Meanwhile, OpenAI maintained throughout the trial that there was never an agreement to remain a nonprofit indefinitely. Its lawyers argued that Musk understood from the beginning that developing cutting-edge artificial intelligence would require extraordinary levels of funding and computing power.

What Happens Next in the Musk-Altman Feud?

The verdict was a clear legal victory for OpenAI at a pivotal moment for the company. OpenAI is deepening its commercial partnerships, expanding its relationship with Microsoft, and moving toward what could become one of the largest public offerings in Silicon Valley history. The company is reportedly valued at more than $800 billion.

For Musk, the ruling leaves room to argue that the case was lost on timing rather than substance. He has decided to appeal, ensuring that the increasingly bitter feud between two of Silicon Valley's most powerful figures is unlikely to end any time soon. The broader debate over artificial intelligence's future and governance remains far from settled, with fundamental questions about transparency, data consent, and the public interest still unresolved in the courtroom and in the wider technology industry.
