Elon Musk lost his lawsuit against OpenAI on Monday after a federal jury in Oakland, California, found that he had waited too long to bring the case. The verdict cleared OpenAI, Chief Executive Sam Altman and other defendants of liability on Musk’s claims that the company had abandoned its founding mission as a nonprofit devoted to benefiting humanity. (usnews.com) Reuters reported that the ruling removed a major legal obstacle to OpenAI’s planned initial public offering. PBS and AP said the jury found Musk missed the deadline set by the statute of limitations. (pbs.org) ### Why did the jury throw out Musk’s case? A nine-person jury found unanimously that Musk filed too late and missed California’s three-year statute of limitations, according to PBS, AP and CBS. (cnbc.com) The jury deliberated for less than two hours before reaching its decision. Judge Yvonne Gonzalez Rogers accepted the verdict and dismissed Musk’s claims. The lawsuit had accused OpenAI and Altman of betraying the original vision Musk says he shared when he helped found the company in 2015. Musk argued that OpenAI’s shift toward a for-profit structure, and its ties with Microsoft, violated that understanding. OpenAI denied wrongdoing and argued that Musk’s case was untimely and driven by rivalry after he left the company. (usnews.com) ### What exactly was Musk alleging? Musk claimed OpenAI had strayed from its original mission to develop artificial intelligence for the public good rather than private gain. He sought damages and other remedies against OpenAI, Altman and related defendants, saying the company’s commercial direction breached the principles on which it had been created. (pbs.org) AP said the case centered on whether OpenAI had betrayed a shared vision for it to remain a nonprofit. Microsoft was also drawn into the dispute because of its relationship with OpenAI. ABC News reported that Musk sought $150 billion in damages and asked that Altman be removed from OpenAI’s board. (apnews.com) OpenAI and Microsoft both denied wrongdoing. ### What did OpenAI say during the trial? Sam Altman and OpenAI argued in court that the dispute was not about charity law or corporate promises but about competition. PBS reported that OpenAI told jurors Musk was seeking a business advantage against a former ally that had become a rival. The company said Musk had known about the changes he challenged for years before filing suit. (usnews.com) The three-week trial produced testimony that drew broad attention across the technology industry. The New York Times reported that, although the jury resolved the case quickly on timing grounds, the testimony offered a detailed look at OpenAI’s evolution and the feud between Musk and Altman. (abcnews.com) ### What does the ruling change for OpenAI now? Reuters reported that the verdict removed a major obstacle to OpenAI’s planned IPO. That matters because the lawsuit had posed legal uncertainty around the company’s structure and governance at a time when OpenAI is competing with Anthropic, Google and Meta in the race to build and sell advanced AI systems. (pbs.org) The New York Times said the ruling leaves OpenAI free to keep pressing that competition. CNBC reported that Musk called the outcome a “technicality” in a post on X and said he would appeal. That means the courtroom fight is not necessarily over, but the immediate verdict leaves OpenAI without the trial-level setback Musk had sought. (nytimes.com) ### What happens next in the case? Musk said on May 18 that he planned to appeal the verdict. Any appeal would move the dispute into the next stage of federal litigation, while OpenAI continues its business preparations outside court. Reuters said the company’s IPO plans were a central reason investors and rivals were watching the trial closely. (cnbc.com) (usnews.com)
