Elon Musk, renowned entrepreneur and owner of SpaceX, Tesla, X (formerly Twitter), and the artificial intelligence startup xAI, has publicly declared his intent to sue Apple. The lawsuit threat comes after Musk’s companies’ flagship applications—X and the Grok AI chatbot—failed to appear in the App Store’s “Must Have” or top recommended apps listings, despite their widespread usage and popularity. This development underscores the intensifying scrutiny of Apple’s app distribution practices and broader antitrust concerns in the global tech ecosystem.

Musk’s Challenge: Alleging Antitrust and Market Manipulation

On Monday night, Musk took to X to voice his grievances. He wrote, “Hey @Apple App Store, why do you refuse to put either X or Grok in your ‘Must Have’ section when X is the #1 news app in the world and Grok is #5 among all apps? Are you playing politics? What gives? Inquiring minds want to know.” Musk further asserted, “Apple is behaving in a manner that makes it impossible for any AI company besides OpenAI to reach #1 in the App Store, which is an unequivocal antitrust violation. xAI will take immediate legal action.”

Musk offered little in terms of concrete legal strategy or specific allegations beyond implied favoritism for OpenAI, the research company that originally developed ChatGPT—the world’s leading AI chatbot app. His public comments, however, immediately sparked debate across the tech community and drew significant attention from regulators and industry watchers.

Apple’s App Store Under Ongoing Antitrust Scrutiny

Apple has faced mounting criticism and legal challenges worldwide over how it runs its App Store. Critics argue that the company’s tight control over which apps are promoted—or even discoverable—distorts competition and potentially harms both consumers and developers. This year, the 27-nation European Union fined Apple 500 million euros (over $550 million) for violating competition rules by preventing app makers from informing users about cheaper alternatives outside the App Store. In 2024, the company was fined nearly $2 billion by the EU for unfairly favoring its own Apple Music service over rivals like Spotify, limiting their ability to promote alternative payment options.

In the United States, Apple was recently found to have violated a court injunction from a lawsuit initiated by Epic Games, the maker of Fortnite. The Epic v. Apple case has put a spotlight on Apple’s 30% commission structure, its anti-steering provisions (which restrict how apps can link to external purchase options), and how App Store curation can bolster certain apps while marginalizing others.

The drumbeat of global regulatory action has forced Apple to alter some of its policies, including allowing developers in some regions to inform users about payment options outside the App Store. However, critics—including influential industry voices like Musk—say these reforms do not go far enough in ensuring a genuinely level playing field.

X and Grok: Market Performance vs. Platform Visibility

X, previously known as Twitter, remains among the most downloaded news and social networking apps worldwide. Musk and his advocates cite data showing X repeatedly topping Apple’s “News” app charts, with millions of active users. Meanwhile, Grok, developed by Musk’s xAI, has rapidly climbed app rankings in the emerging AI chatbot category. According to market analytics firm SensorTower, Grok became the fifth most popular app in its segment within months of launch, competing directly with OpenAI’s ChatGPT.

Despite their popularity and widespread media attention, neither X nor Grok has been highlighted in Apple’s prominent “Must Have” or editorially-curated “Top Apps” features—a coveted spot that can drive massive downloads and brand recognition. As of early Tuesday, the App Store’s top overall apps included TikTok, Tinder, Duolingo, YouTube, Bumble, and OpenAI’s ChatGPT, with no appearance from X or Grok in these sections. Musk’s accusation is that editorial curation by Apple may unfairly hinder the growth of select competitors or push forward certain platforms, raising significant concerns about market manipulation and gatekeeping.

The Broader Fight: Big Tech, Competition, and the Future of Digital Platforms

Musk’s threatened lawsuit comes at a moment when tech giants are locked in fierce battles over digital territory, user data, and the future of artificial intelligence. OpenAI has become the industry leader in AI chatbots following the massive success of ChatGPT, with hundreds of millions of users worldwide. Microsoft, Google, Meta, and others are racing to launch and commercialize their own generative AI solutions. Musk’s xAI is positioning Grok as a more open and less filtered alternative to ChatGPT, frequently citing “freedom of speech” and reduced censorship as its hallmarks.

For Apple, which controls one of the world’s most lucrative distribution points for mobile applications, every decision regarding app visibility and discoverability has enormous ramifications. A place on the “Must Have” or front-page feature drives surges in downloads, user sign-ups, and long-term brand fortunes. Likewise, exclusion from these spaces can stunt growth or disadvantage companies—especially startups and independent developers.

The stakes are sky-high: With the global app market projected to exceed $935 billion in revenue by 2025, the mechanisms of platform curation have become a critical battleground for competition regulators, app developers, and industry moguls alike.

What’s Next for Musk, Apple, and the Tech Ecosystem?

As of this publication, Apple has not commented on Musk’s accusations or the threatened lawsuit. Legal experts say any formal complaint by Musk or xAI would be added to a long list of ongoing investigations and litigation efforts targeting Apple and its App Store policies.

Whether Musk follows through or not, the episode highlights a central tension in today’s digital economy: the immense power wielded by platforms that control digital “gateways” to consumers, and the growing calls by innovators, regulators, and consumers for greater transparency and fairness. As AI chatbots, social apps, and digital services continue to blend, the decisions made by Apple—and contested by rivals like Musk—will help shape the rules of engagement for the next tech generation.
