ChatGPT Share Falls to 56.4% as Gemini Reaches 25% and Claude 9.6%

Summary
ChatGPT captured 56.4% of global AI chatbot web visits in September 2026, down 15.4 percentage points from October 2025 even as it still logged about 5.9 billion visits.
Gemini and Claude drove that erosion: Gemini rose to 25.0% from 13.6%, while Claude climbed to 9.6% from 2.3% and now draws roughly 1.0 billion monthly visits.
Gemini’s gains followed Google’s late-2025 Gemini 3 launch and broad distribution, while Claude benefited from its coding focus, February Super Bowl ads, and a public refusal to support Pentagon mass-surveillance or autonomous-weapons uses.
The market remains highly concentrated, with ChatGPT and Gemini combining for more than 80% of web traffic; DeepSeek, Grok, Copilot, and Perplexity together fell to 8.1% from 11.4%.
ChatGPT’s shrinking share does not mean shrinking usage: after dipping to 53.7% in April 2026, it recovered to 56.4% by September, showing rivals are growing faster rather than OpenAI contracting.
