ChatGPT's growth is bouncing back as rivals struggle to close the gap

Earlier this year, ChatGPT's dominance of the AI market appeared to be slipping as rivals from Google and Anthropic gained momentum. But new research suggests OpenAI's flagship product is making a surprising comeback. ChatGPT now accounts for more than 81% of worldwide traffic to major AI chatbots, according to a study from Graphite, a research and growth marketing firm. No competitor has managed to capture even 10% of the market. That's a striking finding given the attention surrounding Google's Gemini and Anthropic's Claude, which have been widely viewed as increasingly serious threats to OpenAI. The research also challenges the perception that ChatGPT's explosive growth has stalled. After surging through the first half of 2025, ChatGPT usage largely plateaued for seven months.
