ChatGPT’s mobile app has just crossed a major financial milestone, reaching an estimated $3 billion in total worldwide consumer spending across iOS and Android. The figure, based on new estimates from app intelligence firm Appfigures, tallies up purchases made since the app debuted in May 2023, when it first launched on iPhone before later expanding to Android.
The most striking part of the story is how quickly that spending has accelerated. According to the estimates, 2025 accounts for the overwhelming share of ChatGPT’s mobile revenue so far. Consumers worldwide are projected to spend about $2.48 billion in the ChatGPT mobile app in 2025 alone, a massive 408% jump compared with the roughly $487 million spent in 2024. For context, the app generated an estimated $42.9 million in 2023, its first year on the market, before soaring more than tenfold in 2024.
That sharp rise suggests the ChatGPT app isn’t just popular—it’s converting a growing number of users into paying customers at an exceptional rate. In fact, the pace of spending puts it ahead of many of the best-known apps in the world. Appfigures estimates it took ChatGPT just 31 months to reach $3 billion in consumer spending, while TikTok, one of the biggest mobile revenue generators ever, needed 58 months to reach the same mark. The app also hit the milestone faster than major streaming platforms: Disney+ reportedly reached $3 billion in 42 months, and HBO Max did it in 46 months.
The comparison doesn’t stop with entertainment giants. Among AI competitors, xAI’s Grok is showing one of the closest revenue trajectories to ChatGPT. Grok initially launched in late 2023 for X Premium Plus subscribers and then became more widely available last year. When measuring consumer spending from the point each AI app began monetizing, Grok comes closest to matching ChatGPT’s cumulative revenue pace at the same stage—though ChatGPT still leads the category.
Of course, consumer spending inside the mobile app is only one way to measure the long-term business potential of AI. For ChatGPT, that spending is largely driven by subscriptions. Users can pay for tiers like ChatGPT Plus at $20 per month, while power users and advanced customers can opt for a higher-end plan priced at $200 per month.
But subscriptions aren’t the only revenue lever AI companies can pull. AI apps can also earn money through developer products and enterprise offerings, and advertising could become a meaningful factor, too. ChatGPT may be headed further in that direction, especially as it continues to build an ecosystem around the app. This week, ChatGPT launched an in-app “store” experience—an app marketplace-style move that the company has suggested could be monetized in the future.
Meanwhile, the broader AI race is pushing other tech players to rethink their business models. Google is exploring how to weave advertising into a more AI-driven search experience, including placements across features like AI Mode, AI Overviews, AI shopping experiences, and an increasingly AI-influenced Discover feed. At the same time, Anthropic is targeting enterprise adoption and is reportedly aiming for steep growth over the next few years.
The takeaway is clear: ChatGPT’s $3 billion mobile milestone isn’t just a headline number. It highlights a rapid shift in consumer behavior, where AI tools are moving from curiosity to daily habit—and for a growing share of users, something worth paying for every month.
