The Latest Clash in a High-Stakes AI Rivalry

The ongoing rivalry between tech billionaires Elon Musk and Sam Altman erupted into fresh controversy this week as Musk accused Apple of blatant antitrust violations, threatening legal action after claiming the App Store unfairly favors OpenAI. The feud, largely playing out over X (formerly Twitter), has again brought into focus the escalating power struggle among AI’s biggest players and the complex intersection of technology, competition, and regulation.

Musk’s Accusations: Apple ‘Playing Politics’ in the App Store

On Monday evening, Musk shared a pointed post on X from his personal account, alleging Apple was making it “impossible for any AI company besides OpenAI to reach #1 in the App Store”—calling it an “unequivocal antitrust violation.” Specifically, Musk accused Apple of refusing to spotlight Grok, his company xAI’s chatbot, in the “Must Have” section while OpenAI’s flagship ChatGPT app has consistently claimed the top spot.

“xAI will take immediate legal action,” Musk declared in the post. Community notes on X quickly pointed out that other AI apps—including Perplexity and DeepSeek—had reached No. 1 in various App Store rankings in 2025. However, Musk remained adamant that Apple’s practices prevent fair competition for independent AI developers.

Altman Fires Back: Allegations of Manipulation

Sam Altman, CEO of OpenAI and former colleague of Musk, responded publicly, asserting he “heard alleged” that Musk uses his ownership of platforms like X to “harm his competitors and people he doesn’t like,” referencing longstanding reports that Musk has boosted his own social presence through algorithmic tweaks.

Altman linked to a 2023 Platformer report that accused Musk of instructing engineers to amplify his own posts and suppress others—a claim Musk has repeatedly denied. “But OpenAI will just stay focused on making great products,” Altman added, signaling the company’s intent to sidestep personal drama.

A Years-Long Feud Reignites

The public back-and-forth between Musk and Altman is just the latest in a series of confrontations dating back to Musk’s acrimonious 2018 split with OpenAI, an organization he co-founded. In March 2024, Musk filed a lawsuit against OpenAI, accusing it of abandoning its nonprofit mission and aligning too closely with Microsoft—allegations OpenAI vehemently denied. More recently, Altman downplayed Musk’s criticisms during a televised interview, quipping, “You know, I don’t think about him that much.”

Their personal rivalry now unfolds against a backdrop of seismic changes in the AI industry, as rapid advances in generative models have heightened corporate stakes and drawn the eye of regulators around the globe.

The OpenAI–Apple Alliance: Fueling Antitrust Concerns

Fueling Musk’s ire is Apple’s burgeoning partnership with OpenAI, formally announced in June 2024. The collaboration saw Apple integrate ChatGPT capabilities directly into iOS, macOS, and Siri. Apple reportedly prioritized OpenAI’s LLMs (large language models) over other offerings—prompting concerns of gatekeeping and reduced consumer choice.

According to analyst reports, the initial integration was a boon for user engagement, with more than 30% of iPhone users in North America activating AI features powered by OpenAI within the first month. Smaller AI companies have reported difficulty gaining equivalent App Store prominence, echoing Musk’s central complaint.

Antitrust watchdogs have become increasingly vigilant: in July 2025, the U.S. Federal Trade Commission (FTC) and the European Commission confirmed ongoing reviews into Big Tech–AI collaborations to ensure compliance with competitive practices. The Apple–OpenAI alliance is reportedly among the deals being scrutinized.

Market Data: OpenAI’s Lead and Rising Competition

In the wake of Apple’s partnership, OpenAI’s ChatGPT app has consistently dominated App Store download charts, boasting over 150 million downloads globally by mid-2025, according to Sensor Tower. While alternatives like Perplexity AI and novel chatbots from Meta and Google have made inroads, none match OpenAI’s market penetration and Apple’s deep integration.

Musk’s xAI, though hyped for its “truthful AI” claims and aggressively backed by Musk’s online persona, controls a much smaller share of the mobile market. Industry estimates peg Grok’s downloads at fewer than 10 million since its launch—though the technology has attracted critical attention for its anti-censorship stance and raw data outputs.

Regulatory Implications and Industry Reaction

Industry observers caution that Musk’s willingness to litigate reflects broader anxiety about platform control and proprietary advantage as AI becomes increasingly central to global tech strategies. “When one company—whether Apple, Microsoft, or Google—controls which AI products reach billions of users, competition and consumer choice are at stake,” says digital policy analyst Marissa Taylor of the Internet Accountability Project.

Apple has not responded publicly to Musk’s allegations as of this writing. Legal experts say any antitrust case would need to prove exclusionary conduct or preferential treatment beyond algorithmic recommendations—an uphill climb given the opaque nature of App Store curation.

The Broader AI Power Struggle

This public feud ultimately underscores the high-stakes contest to set the rules, standards, and cultural narratives for artificial intelligence around the world. As regulatory scrutiny intensifies in the U.S., EU, and China, tech giants are vying to influence not only who leads in product adoption but also how AI’s future is governed.

Whether Musk’s looming lawsuit produces lasting change or not, the episode reveals deepening unease about monopolistic power in both AI and app distribution. With Apple’s next product event scheduled for September and ongoing regulatory hearings in Washington and Brussels, the coming months promise more sparks—and possibly further escalation in Silicon Valley’s AI wars.
