ChatGPT continues to dominate the artificial intelligence chatbot landscape, according to newly introduced tracking data from Statcounter. The analytics company, best known for monitoring browser, OS, and search engine market share, has begun collecting data on AI chatbot usage, and its findings show that ChatGPT controls more than 80 percent of sessions both in the United States and globally. The numbers support what many already observe—ChatGPT remains the default name in generative AI, far outpacing rivals such as Google Gemini, Microsoft Copilot, Claude AI, and others.
Since Statcounter began reporting AI chatbot usage in March, the rankings have remained relatively stable. ChatGPT’s market share leads by a wide margin, with competing services clustered far below. Some shifts have occurred: Perplexity AI initially showed strong performance, claiming 16 percent of U.S. user sessions in March, but that figure has since declined to just 6 percent. Microsoft Copilot, on the other hand, has shown steady growth, climbing from less than 1 percent to nearly 10 percent in the same timeframe.
Statcounter’s July figures for the U.S. show ChatGPT holding 80.22 percent of the market, followed by Copilot at 9.51 percent, Perplexity at 5.61 percent, Google Gemini at 2.67 percent, Claude AI at 1.56 percent, and Deepseek at 0.43 percent. On a global scale, ChatGPT commands an even greater share at 82.69 percent. Perplexity follows with 8.06 percent, Copilot with 4.56 percent, Gemini at 2.2 percent, Deepseek with 1.59 percent, and Claude trailing at 0.91 percent.
Despite the compelling numbers, Statcounter’s methodology leaves some questions unanswered. The company states it gathers data from over 5 billion monthly page views across 1.5 million websites, using cookies to identify devices, operating systems, and referral sources. While effective for web analytics, it’s unclear how this technique captures activity from AI tools that don’t typically refer users to other websites—an increasingly common trait among generative AI platforms. This self-contained nature is causing concern among online publishers and creators, especially as AI-enhanced search features from Google and others begin answering questions directly.
At the time of writing, Statcounter has not provided clarification regarding how it differentiates or quantifies chatbot-specific activity in its analytics.
