Judge Delivers Final Blow to xAI: Trade Secret Lawsuit Against OpenAI Dismissed With Prejudice

The Core Allegation and the Court's Reasoning

The amended complaint zeroed in on former xAI senior engineer Xuechen Li. xAI alleged that Li disclosed trade secrets during the OpenAI recruitment process and connected this to the July 2025 release of Grok 4 . However, Judge Lin found these allegations insufficient.

The court's reasoning was blunt: xAI "does not point to any misconduct by OpenAI" . The complaint lacked plausible claims that OpenAI directed, encouraged, or induced any former employee to steal or misuse xAI's confidential information. Judge Lin concluded that pointing to several employees who left for OpenAI around the same time was not enough to prove a conspiracy to misappropriate trade secrets .

A Two-Strike Dismissal

This was not the first time the case was thrown out. In February 2026, Judge Lin dismissed the original complaint without prejudice, ruling that xAI had not adequately shown alleged wrongdoing . She granted xAI until March 17, 2026, to file an amended complaint, which the company did. The final June 2026 ruling rejected that amended version definitively, with the judge stating that any further amendment would be "futile" .

Broader Context of the Rivalry

The dismissal is a significant chapter in the increasingly bitter feud between Elon Musk and Sam Altman. This lawsuit was one part of a broader legal and commercial war that included xAI also suing former engineer Xuechen Li individually over the same alleged theft . The case's conclusion comes after xAI was merged into SpaceX, a corporate restructuring that did not change the legal outcome .
