The GenAI Chatbot app market has increased 152% YoY since last January. Google’s Gemini has gone from a 14.7% share of the market in January 2025 to a 25.2% market share in Jan ’26. ChatGPT has fallen from 69.1% to 45.3%. ChatGPT is losing share but this makes sense as new and capable entrants have launched.
Last month, Grok’s DAU market share hit its highest point yet at 15.2%. This is up 3 points from its 12% share in December 2025.
The market is flattening a bit and I think that’s okay. If you’re reading this, you might be surprised to know you are most likely an early adopter of AI. While the technology itself is increasing rapidly, adoption is not as saturated as you might think.
As you can see, most people have never used a GenAI Chatbot app. If you work in tech, this could be mind blowing to realize. Still, the amount of people using multiple AI apps is growing.
About 20% of AI users are using at least two apps; a sign that people are integrating AI in their daily lives and finding out that some apps are better for certain tasks than others.
“ChatGPT built the category, but as viable alternatives have scaled, users are naturally diversifying their toolkit,” said Tom Grant, VP of Research at Apptopia. “The multi-app usage figure is the number I’d watch here. It tells me that people aren’t just experimenting anymore, they’re building workflows around specific products for specific use cases. The market could end up looking like streaming where a few major players own the market but multiple players can carve out niches based on product differentiation rather than pure network effects.”
Claude is still leading Average Time Spent per DAU (34.7 minutes) after its strong December, even with a tick down in January. ChatGPT and CoPilot also notches slight decreases. Perplexity’ rose 34.3% from November to December and had another nice month-over-month gain in January, to the tune of 30.6%. Surprisingly Microsoft CoPilot (the consumer version) has an average time of 27.2 minutes per DAU, good for 2nd best in our list.
