The headline
ChatGPT still leads AI chatbot web traffic with 55.5 percent in August 2026, but it has fallen from 73.3 percent a year earlier as Gemini roughly doubled to 25.6 percent and Claude rose to 9.3 percent. India is a top market for several assistants, including 100 million weekly ChatGPT users.
Worldwide chatbot web traffic share
Similarweb estimates of worldwide website visits, August 2026 compared with August 2025.
Website traffic only. It leaves out mobile apps and system-level entry points such as Android or Windows, so it understates assistants that live inside other products.
