ChatGPT lost 22 points of web share in a year

Similarweb global web-visit share shows ChatGPT dropped from 76% to 54% over the past year, while Gemini rose from 6% to 28% and Claude from 1% to 9%. These are web-traffic shares, not monthly users or revenue. Gemini's 1B app MAU can coexist with ~28% web share because most Gemini use happens in-app or on Android. Data is through May 2026, charted Aug 12.

Why it matters: Solid Similarweb web-share data with clear numbers and source attribution. The shifts are large enough to be newsworthy. Held below 80 because it's a single data source, web-only, and comes via an echohive briefing rather than a primary report.
