ChatGPT's web traffic dominance eroded significantly in the past year, dropping from 77.6% to 53.7% of AI chatbot traffic. Google's Gemini captured the momentum, nearly quadrupling its share from 7.3% to 26.7%.
The shift marks a dramatic change in the AI chatbot landscape, according to traffic analysis firm Similarweb. ChatGPT's lead, while still substantial, has narrowed considerably as competition intensifies.
Google's Gemini emerged as the primary beneficiary of ChatGPT's decline. The search giant's AI assistant grew its traffic share nearly fourfold in twelve months, establishing itself as a serious contender in the generative AI space.
Other AI chatbots collectively account for the remaining traffic share, though no single competitor has matched Gemini's growth trajectory.
The data reflects web traffic only and does not include API usage, mobile applications, or enterprise deployments. This distinction matters: many users access ChatGPT through third-party apps and integrations rather than visiting the website directly. The full picture of user adoption remains unclear without API and app usage figures.
Gemini's rise reflects Google's strategic push to compete with OpenAI. The company integrated Gemini into search, Gmail, and other products, lowering the friction for users to try the service. Free access and tight integration with Google's ecosystem likely contributed to the traffic growth.
ChatGPT's decline from near-monopoly levels appears inevitable given market maturation and increased competition. OpenAI continues to expand its offering with paid tiers, enterprise plans, and custom GPT models.
The web traffic metrics suggest users are diversifying their AI chatbot usage rather than abandoning the category entirely. The growing availability of open-source models and smaller specialized AI tools may also fragment the market further.
Similarweb's methodology measures relative traffic share among major AI chatbot websites. Absolute traffic numbers for individual services remain proprietary information controlled by the companies themselves.
