In a groundbreaking shift, the year 2025 witnessed a remarkable milestone: consumers worldwide spent more on non-game mobile apps than on games. This trend, as revealed by Sensor Tower's annual "State of Mobile" report, signifies a global phenomenon with profound implications. With a staggering $85 billion spent on apps, marking a 21% increase from the previous year, and nearly tripling the amount spent five years ago, the mobile app market is experiencing an unprecedented boom.
But here's where it gets controversial: the driving force behind this boom is none other than AI-powered apps. Generative AI, a buzzword of the past year, has led the charge, with in-app purchase revenue in this category skyrocketing to over $5 billion in 2025. Downloads of AI apps have also doubled, reaching an impressive 3.8 billion.
So, what's fueling this AI app revolution? Well, it's a combination of factors. Firstly, the immense popularity of AI assistants among consumers cannot be overstated. The top 10 downloaded apps were all AI assistants, with OpenAI's ChatGPT, Google Gemini, and DeepSeek leading the pack. ChatGPT alone generated a whopping $3.4 billion in global in-app purchase revenue, a figure that speaks volumes about its impact.
In 2025, consumers spent a staggering 48 billion hours in generative AI apps, a 3.6x increase from 2024 and a 10x jump from 2023. Session volume, a key indicator of user engagement, topped one trillion in 2025, with existing users deepening their engagement faster than new users were added.
Another crucial factor is the heavy investment by big tech companies like Google, Microsoft, and X in their AI assistants to challenge ChatGPT. Over the past year, these companies have been rapidly rolling out new capabilities, improving in areas such as coding assistance, content generation, reasoning, task execution, and accuracy. The report specifically highlights advancements in image and video generation, with ChatGPT's GPT-4o image generation model and Google's Nano Banana taking center stage.
Among the top AI publishers, OpenAI and DeepSeek have seen their global downloads nearly double, increasing from 21% in 2024 to almost 50% in 2025. Meanwhile, big tech publishers have also made significant gains, growing their market share from 14% to nearly 30%, leaving earlier ChatGPT competitors like Nova, Codeway, and Chat Smith in the dust.
The report further emphasizes the crucial role of mobile devices in connecting users to generative AI services. Sensor Tower estimates that the total audience for AI assistants in the U.S. topped 200 million by the end of 2025, with more than half (110 million) accessing these assistants exclusively on mobile devices. This is a significant shift from 2024, when only around 13 million users were mobile-only.
While AI apps have undoubtedly been a major revenue driver, Sensor Tower's report also highlights the contributions of other app categories. Social media, video streaming, and productivity apps have played a significant role in fueling the growth, with consumers spending an average of 90 minutes per day on social media apps, totaling nearly 2.5 trillion hours, a 5% increase from the previous year.
This shift in consumer spending patterns raises intriguing questions: What does this mean for the future of the gaming industry? How will AI continue to shape the app market? And most importantly, how can developers and businesses adapt to this new landscape? Join the discussion in the comments and share your thoughts on this AI-driven revolution.
