ChatGPT Rebounds to 55.5% Web Traffic Share as Rivals Narrow the Annual Lead

According to Similarweb data, ChatGPT has reclaimed 55.5 percent of global AI chatbot web traffic, checking recent gains by competitors. The year-over-year trajectory, however, underscores a structural shift: OpenAI previously held 73.3 percent of the market, but Gemini has since doubled its share and Claude has grown nearly fivefold. While these metrics do not capture native desktop and mobile app usage, they indicate that early unilateral dominance is giving way to a sustained multi-model race.
