ChatGPT's traffic share drops to 57% in a year, Gemini surges to 25%

ME News report, April 16 (UTC+8): According to monitoring by Beating, Similarweb has released generative AI website traffic share data through March 2026. Over the past 12 months, ChatGPT’s share declined from 77.43% to 56.72%, losing over 20 percentage points; Gemini’s share rose from 6.00% to 25.46%, more than quadrupling and capturing the majority of the lost market share. March share breakdown by product: 1. ChatGPT: 56.72% 2. Gemini: 25.46% 3. Claude: 6.02% 4. DeepSeek: 3.74% 5. Grok: 3.44% 6. Copilot: 1.99% 7. Perplexity: 1.64% The most dramatic short-term change was seen with Claude: one year ago, it held just 1.40%, stood at 2.22% in January, and surged past 6% in March, nearly doubling from February to March alone. Grok dropped from second place (7.03%) a year ago to fifth (3.44%), overtaken by DeepSeek. Copilot’s growth was partly due to a change in measurement methodology, as Similarweb now includes traffic from microsoft.com/m365.cloud/chat under Copilot. A year ago, ChatGPT dominated with a 77% share; today, the top two combined account for 82% (ChatGPT at 57% and Gemini at 25%), shifting the landscape from a monopoly to a duopoly. Their growth patterns differ sharply: Gemini rose steadily quarter by quarter, while Claude remained nearly flat for the first ten months before surging from 2% to 6% in the last two months. Grok suffered the steepest decline—once ranked second a year ago, it is now surpassed by three competitors. (Source: BlockBeats)
