OpenAI says SEC disclosures undermine xAI’s antitrust lawsuit

Apple, OpenAI and xAI did not immediately respond to requests for comment.

The case is X Corp and SpaceXAI v OpenAI, US District Court for the Northern District of Texas, No. 4:25-cv-00914-P.

ChatGPT maker OpenAI asked a Texas federal judge to throw out an antitrust lawsuit brought by Elon Musk's AI startup xAI before trial, arguing that disclosures by xAI parent company SpaceX undermine claims that Apple's partnership with OpenAI shut out rivals.

OpenAI on Tuesday asked US District Judge Mark Pittman in Fort Worth to rule for OpenAI based on the facts so far in the case, which is now set for a trial in January.

Musk’s companies sued Apple and OpenAI last year, alleging Apple violated antitrust law by exclusively integrating ChatGPT into Apple Intelligence features on iPhones and other Apple devices.

Apple and OpenAI have denied any wrongdoing. Apple previously said its integration deal with OpenAI was not exclusive. X said last week it has settled with Apple, but the terms have not been disclosed.

OpenAI’s new court filing argued that deposition testimony and other evidence bolstered its defense, including recent securities disclosures from Musk’s SpaceX, which began publicly trading in June.

SpaceX’s initial public offering registration statement, OpenAI said, is “replete with disclosures diametrically opposed” to xAI's claims of competitive harm alleged in its lawsuit. The registration “bears no resemblance to the doomsaying in this litigation,” it said.

OpenAI denied it wields monopoly power, a necessary element to prove antitrust violations.
