ChatGPT Market Share: 2025 Trend

Below you will find the YTD 2025 trend of ChatGPT’s market share in the generative AI chatbot space. As the pioneer and marketplace leader, it has the most to lose, and it has seen a decline in market share this year at the hands of its many smaller competitors.

NOTE: ChatGPT’s market share includes that of Bing’s Copilot product, as they both use the same underlying system; the difference is only that Microsoft Copilot personalizes ChatGPT based on user data in the Microsoft ecosystem.
