Apple collected nearly $900 million in App Store fees from generative AI apps in 2025, according to data from analysis firm AppMagic, covered by The Wall Street Journal ($). The overwhelming majority of Apple's AI app commission revenue came courtesy of ChatGPT downloads leading to subsequent subscriptions, which alone accounted for around 75 percent of the above total. Elon Musk's Grok app came a distant second, making up just 5 percent of the revenue.
