xAI Sues Former Engineer, Alleging He Took Grok Trade Secrets to OpenAI

xAI seeks damages with a restraining order following what it calls an August 14 admission.

Overview

  • The complaint filed Thursday in California federal court accuses Xuechen Li of copying Grok-related files on July 25 to personal systems after selling about $7 million of xAI stock.
  • Li resigned a few days later for a role at OpenAI, and xAI says he acknowledged the misappropriation during an August 14 meeting before later forensics found more material on his devices.
  • xAI asks for unspecified monetary damages and a temporary restraining order to block Li’s move, with filings citing a planned August 19 start date at OpenAI.
  • The suit details steps it says Li took to hide the transfers, including deleting browser history, clearing system logs, and compressing and renaming files.
  • OpenAI is not named as a defendant and did not immediately comment, and the case expands a broader legal fight that also features a Texas antitrust action against OpenAI and Apple.
