A U.S. federal judge has refused to dismiss a high-profile antitrust lawsuit brought by X Corp and its AI-spin-out xAI against Apple and OpenAI, allowing the case to move forward.
The decision, issued by Mark Pittman of the U.S. District Court in Fort Worth, Texas, does not opine on the merit of the claims made by X and xAI, it simply means the complaint is legally sufficient to survive the initial procedural challenge.
Filed in August 2025, the lawsuit alleges that Apple and OpenAI conspired to monopolise the smartphone and generative-AI chatbot markets.
Key points raised by X and xAI include:
- Apple’s integration of OpenAI’s ChatGPT into its “Apple Intelligence” features across iPhones, iPads and Macs, which the plaintiffs claim is exclusive and shuts out rival chatbots.
- Apple allegedly featured ChatGPT prominently (e.g., via its “Must-Have Apps” list in the App Store) while giving lesser visibility to competing apps such as xAI’s Grok.
- The suit claims this combination of device-integration and App Store placement amounts to anticompetitive conduct under U.S. antitrust laws.
Apple & OpenAI’s Defence
In their bid to have the case dismissed, Apple and OpenAI argued:
- The partnership between Apple and OpenAI is not exclusive; Apple is free to work with other generative-AI providers.
- Choosing one partner first is not unlawful and does not automatically equate to anticompetitive behaviour.
- Rivals, including X and Grok, remain available in the App Store and via browsers, undermining the exclusivity assertion.
OpenAI additionally denounced the lawsuit as part of what it called a “pattern of harassment” by Musk’s companies.
Why the Ruling Matters
This ruling is significant for several reasons:
- It signals that the court believes X and xAI’s complaint contains sufficient legal allegations to carry the case further, a procedural win for Musk’s side.
- The case touches on two major themes: the dominance of Big Tech in AI deployment and the power of mobile-app ecosystems (particularly Apple’s) in shaping competitive access.
- For Apple and OpenAI, the ruling means they face discovery, fact-finding and potentially a full trial rather than having the complaint disposed of on a motion to dismiss.
- For X and xAI, the decision boosts their ability to investigate Apple and OpenAI’s internal dealings, contracts and App-Store decisions, something that could reveal industry-shaping practices.
Importantly, Judge Pittman’s order is not a finding that Apple and OpenAI violated antitrust laws. He explicitly stated that the ruling “should not be seen as a judgment on the merits” of X’s allegations.
What it does is allow X’s claims to proceed past the threshold of legal sufficiency. The factual disputes such as whether the partnership truly was exclusive, whether Apple’s App Store placement harmed competition, etc. will be addressed in subsequent phases.
In summary: While the U.S. judge’s ruling does not resolve whether Apple or OpenAI have broken the law, it marks an important step in a high-stakes legal battle. The lawsuit by X Corp and xAI against Apple and OpenAI will carry on, digging into how device-makers and AI providers interrelate and potentially influencing the broader architecture of mobile, AI and app ecosystems.
