TL;DRA federal judge dismissed xAI’s trade secret lawsuit against OpenAI with prejudice, ruling it would be “futile” to continue. It is Musk’s second court loss against OpenAI in four weeks, following the May jury verdict that rejected his $150 billion claim on statute of limitations grounds.
A federal judge has permanently killed xAI’s lawsuit accusing OpenAI of stealing trade secrets related to the Grok chatbot. US District Judge Rita Lin dismissed the case with prejudice on Monday, meaning xAI cannot bring the same claims again.
Lin said xAI failed to show that OpenAI induced former xAI senior engineer Xuechen Li to divulge confidential information, or that OpenAI engineers even knew Li might have disclosed any. Allowing further amendment, she wrote, would be “futile.”
A routine interview, not espionage
The case turned on a presentation Li gave while OpenAI was recruiting him. xAI alleged OpenAI sought secrets related to the July 2025 release of Grok 4, claiming its own ChatGPT update “could not compete” on complex reasoning and that it was “lagging” in the reinforcement learning techniques Li understood.
