Elon Musk’s artificial-intelligence venture xAI, together with social-media parent X Corp., filed a 61-page antitrust lawsuit against Apple and OpenAI in a U.S. federal court in Texas on 25 August. The complaint accuses the iPhone maker and the ChatGPT developer of colluding to keep rival chatbots off Apple’s devices and to suppress competitors in App Store rankings, thereby locking up the smartphone and generative-AI markets. Musk’s companies allege that Apple’s deep integration of ChatGPT into iOS makes it “impossible for any AI company besides OpenAI to reach No. 1,” and they are seeking at least US$1 billion in damages as well as an injunction to unwind the partnership. The suit argues that Apple’s roughly 65 percent share of the U.S. smartphone market, combined with OpenAI’s dominance in conversational AI, creates a tandem monopoly that echoes distribution deals targeted in other recent antitrust actions. OpenAI called the allegations part of Musk’s “ongoing pattern of harassment,” while Apple has not publicly responded in the filings reviewed. The case adds a new front to Musk’s wider legal battle with OpenAI: two days after the Texas filing, Musk’s lawyers asked a judge to block OpenAI from obtaining Meta documents tied to an earlier US$97.4 billion bid for the startup’s assets. The outcome of the Texas action could shape how regulators and courts view exclusive AI distribution deals on mobile platforms.
