News Summary

Recent data from Sensor Tower highlights a shift in the AI chatbot market, with OpenAI’s ChatGPT experiencing a slowdown in user growth. Although still the leader, accounting for 50% of global downloads and 55% of global monthly active users, ChatGPT’s growth from August to November 2025 was only 6%. In contrast, Google’s Gemini saw a 30% increase in the same period, driven by the success of its image generation model, Nano Banana. Gemini has increased its share of global monthly active users by three percentage points over the past seven months, while ChatGPT’s share has decreased by the same margin. The competition is heating up as other chatbots like Perplexity and Claude report significant growth, posing challenges to ChatGPT’s dominance.
