Elon Musk Loses Lawsuit: Federal Judge Dismisses xAI’s Trade Secret Claims Against Sam Altman-Led OpenAI, Citing Lack of Evidence
A federal judge has dismissed with prejudice a trade secret lawsuit filed by Elon Musk’s xAI against OpenAI. The court ruled that xAI failed to prove OpenAI induced a former employee to leak confidential chatbot data. This marks Musk’s second major legal loss against the AI firm in four weeks, with the judge citing standard recruitment practices.
A federal judge in San Francisco has dismissed a lawsuit brought by Elon Musk’s artificial intelligence company, xAI, which accused OpenAI of misappropriating trade secrets related to chatbot technology. U.S. District Judge Rita Lin ruled on Monday that xAI failed to provide evidence that OpenAI induced a former senior engineer, Xuechen Li, to disclose confidential information regarding the Grok chatbot.

The lawsuit, initially filed in September 2025, alleged that OpenAI sought proprietary information to compete with the release of Grok 4. Musk’s company claimed that OpenAI was lagging in specific training techniques and pressured the engineer to divulge secrets during the recruitment process.

However, Judge Lin dismissed the case with prejudice, determining that any further attempt to amend the complaint would be futile. The judge noted that it is standard industry practice for employers to inquire about a candidate’s past work experience during recruitment. She stated that inferring wrongdoing from such routine discussions would unfairly expose employers to potential legal liability whenever they interview prospective staff.
Ongoing Legal Conflict Between Musk and OpenAI
This ruling marks the second significant legal defeat for Elon Musk against OpenAI within the last four weeks. In mid-May, a federal jury ruled against Musk in a separate USD 150 billion lawsuit, which had accused OpenAI and its CEO, Sam Altman, of betraying the firm’s original non-profit mission for personal financial gain.

OpenAI welcomed the dismissal, describing the legal action as a baseless campaign of harassment. The company has consistently maintained that it never acquired any trade secrets from xAI. While xAI and its legal representatives have not commented on the latest court decision, the engineer in question, Xuechen Li, remains involved in separate litigation initiated by xAI and continues to deny any allegations of wrongdoing.
