At the time of writing, ChatGPT is listed as Apple’s top free iPhone app in the US, with Grok ranked as the sixth. China’s DeepSeek AI briefly managed to take the top App Store position from ChatGPT in January, however, disproving Musk’s claim that it would be impossible for other AI apps to do so.

Musk threatens to sue Apple for allegedly favoring ChatGPT and blocking other AI rivals from the App Store's top spot. Altman notes that Musk was accused of juicing his own algorithm on X.

Musk has not yet provided evidence that Apple has suppressed his apps. As of this writing, ChatGPT is the top app on the Apple App Store charts; Grok is in the fifth spot, lagging behind Threads.
