ChatGPT has reached a new milestone of three billion dollars in worldwide consumer spending on mobile devices. This estimate comes from the app intelligence provider Appfigures. The figure represents the total spending on iOS and Android since the app launched in May 2023, when it was initially available only on iOS.
What is particularly notable is that the majority of this spending occurred in the current year. Worldwide, consumers spent an estimated 2.48 billion dollars in the ChatGPT mobile app in 2025. This represents a 408 percent year-over-year increase from the 487 million dollars spent in 2024. In its first year of availability in 2023, the app earned 42.9 million dollars before growing by 1,036 percent to reach the 2024 figure.
These numbers indicate a sharp rise in consumer adoption compared to other popular apps. For instance, it took ChatGPT just 31 months to reach three billion dollars in consumer spending. In contrast, the top earner TikTok took 58 months to achieve the same milestone. ChatGPT also reached this figure faster than leading streaming apps like Disney+ and HBO Max, which hit three billion dollars in 42 months and 46 months, respectively.
Among AI rivals, xAI’s Grok is seeing a revenue trajectory similar to ChatGPT. Grok was released in late 2023 to X Premium Plus subscribers before becoming more broadly available last year. When comparing the pace of consumer spending across AI apps, Grok came the closest to matching ChatGPT’s cumulative revenue at the same point after each began monetizing.
While the three billion dollars in spending marks significant consumer uptake, it is not the only measure of AI app adoption or potential long-term revenue. ChatGPT’s mobile customers are purchasing paid subscriptions, such as the twenty-dollar-per-month ChatGPT Plus or the two-hundred-dollar-per-month ChatGPT Pro for advanced users. However, AI apps can generate revenue through other means, including developer offerings and potentially advertisements in the future. Additionally, ChatGPT recently launched its own app store, which the company suggests will be monetized in some way going forward.
Other companies are exploring different revenue models for AI. Google is examining ways to transition its search ads business to AI-powered search, placing ads within features like AI Mode, AI Overviews, AI shopping tools, and an increasingly AI-powered Discover page. Meanwhile, Anthropic is targeting the business market and is reportedly on track to reach seventy billion dollars in revenue by 2028.
