Elon Musk’s AI startup xAI plans legal action against Apple, accusing it of favoring OpenAI’s ChatGPT in App Store rankings and blocking competitors like xAI’s Grok. ChatGPT currently leads the US iPhone App Store, with Grok in fifth place, according to Reuters.

Musk also questioned Apple’s refusal to feature xAI apps in the “Must Have” section. Apple, OpenAI, and xAI have not responded to the allegations.

The dispute comes amid growing regulatory scrutiny and recent legal actions against Apple’s App Store practices, Reuters reported.
