Data from Sensor Tower reveals ChatGPT’s growth is slowing, suggesting it might be nearing market saturation. While still leading with 50% of global mobile downloads and 55% of monthly active users (810 million in November 2025), Google’s Gemini is experiencing faster growth in downloads, active users, and engagement, particularly with its image generation model, Nano Banana. ChatGPT’s monthly active user growth slowed to 6% (Aug-Nov 2025), while Gemini jumped 30%. OpenAI is responding with a focus on improving its AI. Perplexity and Claude also show substantial growth, intensifying competition.
