A U.S. federal judge has dismissed Elon Musk’s xAI trade secrets lawsuit against OpenAI, handing the ChatGPT maker a clear legal victory in one of their ongoing battles.
On February 24, 2026, U.S. District Judge Rita F. Lin in San Francisco granted OpenAI’s motion to dismiss the case (3:25-cv-08133-RFL) with leave to amend. The ruling means xAI can refile by March 17, 2026, but must fix critical pleading deficiencies first.
xAI filed the lawsuit in September 2025, accusing OpenAI of systematically poaching eight former employees to steal confidential information. The complaint highlighted alleged thefts of Grok source code, model training methods, and data-center deployment strategies. Specific claims involved engineer Xuechen Li uploading code during an OpenAI interview process, Jimmy Fraiture copying files before joining, and a senior finance executive refusing to certify return of materials.
Judge Lin ruled that xAI failed to allege any direct misconduct by OpenAI itself. In her order she wrote:
“Notably absent are allegations about the conduct of OpenAI itself. xAI does not allege any facts indicating that OpenAI induced xAI’s former employees to steal xAI’s trade secrets or that these former xAI employees used any stolen trade secrets once employed by OpenAI.”
The court found the claims under the federal Defend Trade Secrets Act and California Unfair Competition Law insufficient. There were no facts showing OpenAI knew about, encouraged, or benefited from the alleged thefts. Judge Lin emphasized that simply hiring ex-employees who may have taken materials does not automatically create liability without evidence of use or inducement at OpenAI.
OpenAI welcomed the decision, calling the suit “baseless” and part of Musk’s “ongoing campaign of harassment.” The case is one front in a larger feud that includes Musk’s separate $134.5 billion lawsuit against OpenAI over its shift to a for-profit model.
Legal experts note the dismissal was expected after Judge Lin signaled her tentative view in January. The ruling sets a high bar for proving corporate liability in employee-poaching trade-secret cases.
xAI has not yet commented publicly on next steps, but the option to amend keeps the dispute alive. Industry watchers will monitor whether strengthened allegations appear by the March deadline or if the case fades.
The decision underscores the challenges AI startups face when proving trade-secret theft in fast-moving talent wars. For now, OpenAI has successfully defended itself against claims it stole xAI’s crown jewels.
