ChatGPT Maintains AI Dominance Amid Slowing Growth, Google’s Gemini Gains Traction
ChatGPT continues to lead the AI assistant market with 50% of global mobile downloads and 55% of monthly chatbot users, according to Sensor Tower data. Yet its growth rate has slowed to just 6% between August and November 2025, suggesting potential market saturation. Meanwhile, Google's Gemini is gaining momentum across key metrics—new downloads, active users, and engagement time—prompting OpenAI CEO Sam Altman to issue a "code red" memo urging improvements in personalization, functionality, and image generation.
Both platforms show robust year-over-year user growth: ChatGPT's monthly users surged 180% to 11.5 million, while Gemini trailed closely with 170% growth. The competition underscores a pivotal moment in AI adoption, where user experience and innovation may determine the next leader in this high-stakes sector.
