Accusing the iPhone maker of breaching antitrust regulations in managing the App Store rankings, billionaire Elon Musk said that his artificial intelligence startup xAI would take legal action against Apple. Musk did not, however, provide evidence to support his claim but wrote in a post on X that Apple is behaving in a manner that makes it impossible for any AI company besides OpenAI to reach #1 in the App Store.

Elon Musk’s apparent grievance against Apple is that despite good rankings, products like X and Grok are not receiving prominent placement in Apple's 'Must Have' section, despite their high popularity. He accused Apple of playing politics by ignoring the apps, which are top contenders in their categories.

Currently, ChatGPT holds the top position in the US iPhone App Store’s “Top Free Apps” section, while Musk’s AI startup, xAI, ranks fifth with its Grok app. Google’s Gemini chatbot lags far behind in 57th place. ChatGPT also leads in rankings on the Google Play Store, according to Sensor Tower data.

Musk’s accusations come amid rising tension between his xAI and OpenAI, two major players in the AI industry. Musk's comments about Apple's bias have reignited the ongoing rivalry between the two companies, especially in the wake of OpenAI's recent launch of its GPT-5 model.
