FAQ
AI search, plain answers.
How many people use ChatGPT in 2026?
ChatGPT passed 900 million weekly active users in early 2026, roughly double a year earlier, and processes around 2.5 billion prompts per day. Google’s Gemini app reached about 900 million monthly users and Google AI Overviews reach 1.5 billion monthly users.
What is ChatGPT’s market share among AI assistants?
It depends on the methodology. By assistant market share, First Page Sage put ChatGPT at 46.4% globally by May 2026, down from 65.3% in December 2024, with Gemini at 27.7% and Claude at 10.3%. StatCounter’s web-based measurement showed a much higher 76.85% in April 2026. The direction is consistent: ChatGPT is still first but losing share to Gemini and Claude.
Do people click through from AI search?
Mostly not. About 93% of AI search sessions end without a website click, and an AI Overview cuts the top page’s click-through rate by 58%. That is why getting cited inside the answer matters more than ranking a link.
