Musk’s xAI Sues Apple, OpenAI Over Alleged Antitrust Violations in AI Market

Elon Musk’s artificial intelligence startup, xAI, has filed a federal lawsuit in Texas against Apple Inc. and OpenAI, accusing the two companies of conspiring to stifle competition in the fast-growing AI market. The suit, which seeks billions of dollars in damages, raises fresh antitrust concerns over Apple’s integration of OpenAI’s ChatGPT into its operating systems.

According to the filing, Apple and OpenAI have entered into exclusive arrangements that “lock up markets” and prevent innovators such as Musk’s X platform and xAI’s Grok chatbot from competing fairly.

“If not for its exclusive deal with OpenAI, Apple would have no reason to refrain from more prominently featuring the X app and the Grok app in its App Store,” the lawsuit alleges.

Musk’s Position

Musk, who acquired X (formerly Twitter) in 2022 for $33 billion to bolster xAI’s data and training capabilities, has repeatedly criticized Apple for giving preferential treatment to OpenAI.

On his X platform, Musk wrote:

“A million reviews with 4.9 average for @Grok and still Apple refuses to mention Grok on any lists.”

Earlier this month, Musk accused Apple of manipulating App Store rankings to ensure OpenAI’s dominance, calling it an “unequivocal antitrust violation.”

Responses and Counterpoints

OpenAI dismissed Musk’s claims, calling the lawsuit “part of his ongoing pattern of harassment.” Apple has yet to issue an official response.

Legal experts say xAI’s case could hinge on Apple’s dominant position in the smartphone market. By embedding ChatGPT into iOS, iPadOS, and macOS, Musk argues, Apple is effectively tying hardware sales to one AI provider.

However, Apple could defend its partnership as a legitimate business decision in a competitive landscape, with arguments that the integration was driven by security and performance considerations rather than anticompetitive intent.

Herbert Hovenkamp, a University of Pennsylvania antitrust scholar, noted that the case could force U.S. courts to address a threshold issue: whether AI represents a distinct market under antitrust law.

Broader Context

• OpenAI’s ChatGPT became the fastest-growing consumer app in history after launching in late 2022.
• Apple announced earlier this year it would embed ChatGPT into iPhones, iPads, and Macs, making the chatbot a default option for millions of users.
• Musk’s xAI, founded in 2023, launched the Grok chatbot, now integrated into Tesla vehicles as well as the X platform.
• Musk has also filed separate suits against OpenAI, arguing that the company’s shift from a nonprofit to a for-profit structure violated its founding mission. He even led a $97.4 billion takeover bid aimed at returning OpenAI to nonprofit status, which CEO Sam Altman rejected.
• Apple has faced prior antitrust battles over its App Store practices, most notably with Epic Games, the maker of Fortnite.

What’s Next

The case could provide the first major test in U.S. courts of how regulators and judges define the boundaries of the AI market — and whether Apple’s control over its ecosystem unfairly disadvantages rivals.
