Google Gemini is approaching double-digit share, and the combined challengers now hold more than 23% of the referral market.

New market figures have suggested OpenAI’s ChatGPT is gradually losing referral share as competitors gain ground across the increasingly competitive AI chatbot industry.

The latest data from Statcounter claims ChatGPT accounted for 76.85% of AI chatbot referrals in April 2026 - which may sound high, but actually marks the platform’s lowest recorded share after three consecutive months of losses for OpenAI, which stood at over 84% just a year ago.

Google Gemini continues to grow, reaching an all-time high of 9% share and holding second place for two consecutive months, with Perplexity and Copilot also both bouncing back after months of decline, while a recent spike for Claude has started to cool.
