A federal judge in Texas has ordered Elon Musk’s companies to disclose any agreements with Apple that may explain why they dropped antitrust claims against the technology giant. Judge Mark Pittman, who oversees the case in the Northern District of Texas, issued the order Wednesday after OpenAI asked the court to compel X Corp. to provide information about its resolution with Apple. The order seeks documents related to the decision by X Corp. and SpaceXAI to dismiss their claims against Apple. The companies filed a request to voluntarily dismiss the Apple portion of their lawsuit Tuesday without explaining why. They said they would continue pursuing antitrust claims against OpenAI. The court’s demand for settlement information raises questions about whether an agreement between Musk’s businesses and Apple influenced the dismissal. The companies have not publicly described any such arrangement. Musk’s lawsuit accuses Apple and OpenAI of working together to preserve their power in the rapidly expanding artificial-intelligence market. The complaint describes the companies as “two monopolists joining forces to ensure their continued dominance” and alleges that Apple manipulated rankings in its App Store to favor OpenAI’s products. The case also challenges Apple’s 2024 agreement to integrate OpenAI’s ChatGPT into the iPhone. Apple has reportedly reached a new agreement this year to incorporate Google’s artificial-intelligence services into its products, adding another major player to the competition over AI tools and distribution. The dispute carries implications beyond the companies involved. Apple controls access to a vast mobile-device ecosystem, while OpenAI, Google and Musk’s businesses are competing for influence over the software and services that may shape the next generation of consumer technology. Antitrust scrutiny of those relationships could affect how AI products reach users and whether dominant platforms can favor selected providers. Pittman’s order does not resolve the underlying antitrust claims or determine whether Apple, OpenAI or Musk’s companies violated competition law. It requires Musk’s businesses to provide the judge with any relevant agreements so the court can examine the circumstances surrounding the dismissal.
