ChatGPT web traffic share has climbed to approximately 56% of worldwide generative AI chatbot website traffic, while Google Gemini has slipped to 25%, according to September 2026 figures attributed to Similarweb. The latest numbers suggest OpenAI is regaining ground after a period in which Google’s AI assistant made significant gains against its biggest rival. (OfficeChai)
The shift is notable because Gemini had substantially narrowed the gap over the previous year. ChatGPT’s recent recovery, combined with Gemini’s consecutive monthly declines, raises fresh questions about whether Google can maintain its momentum in the increasingly competitive AI assistant market.
However, website traffic share is only one measure of competition. Mobile applications, integrations, enterprise deployments and API usage can influence the broader market without appearing in website-visit statistics.
This article examines the latest ChatGPT web traffic share figures, how Gemini’s position has changed, what the numbers reveal about user behaviour, and what businesses should understand when choosing AI platforms.
