Judge dismisses xAI trade secret lawsuit vs OpenAI

xAI Loses Second Legal Battle Against OpenAI in Four Weeks

U.S. District Judge Rita F. Lin dismissed Elon Musk's xAI trade secret lawsuit against OpenAI on Monday, June 16, 2026, in the U.S. District Court for the Northern District of California. The dismissal was issued with prejudice and without leave to amend, meaning xAI cannot refile the same claims Courthouse News.

xAI accused OpenAI of misappropriating confidential information related to its Grok chatbot through former engineer Xuechen Li. However, Judge Lin found that xAI had failed to demonstrate that OpenAI induced Li to divulge the secrets or that OpenAI engineers knew Li was disclosing confidential material Bloomberg Law.

Judge Cites Absence of OpenAI Misconduct

In her ruling, Judge Lin stated that "mere possession of trade secrets is not sufficient to constitute misappropriation" and noted that allegations were "notably absent" regarding OpenAI's own conduct WSJ. She wrote that allowing further amendment would be "futile."

This marks the second major legal loss for Musk against OpenAI in four weeks. In May 2026, a jury rejected his $150 billion antitrust claim on statute of limitations grounds. No fines, penalties, or monetary awards were issued in this dismissal.

Separate Litigation Against Engineer Continues

xAI is pursuing a separate lawsuit against Xuechen Li directly, though Li has denied wrongdoing. OpenAI welcomed the ruling, stating through official channels that the claims were "entirely unfounded" Engadget.

This case mirrors xAI's earlier February 2026 dismissal. xAI amended its complaint following that ruling but again failed to cure the core deficiency: proving OpenAI's own inducement or knowledge of the disclosure.
