ChatGPT’s global web traffic share drops 24 percentage points in a year as competitors like Gemini and Claude expand rapidly.
OpenAI’s ChatGPT saw its global web traffic share decline from 77.6% in May 2025 to 53.7% in April 2026, a 24-point drop over 12 months. The shift reflects broader fragmentation in the generative AI market, with no single rival capturing the lost share.
Google’s Gemini surged from 7.27% to 26.7% in the same period, while Anthropic’s Claude rose from 1.37% to 7.95%. Business adoption data shows Anthropic now leads OpenAI, with 34.4% of companies tracked using its tools versus OpenAI’s 32.3%.
Secondary markets value Anthropic at $1 trillion, surpassing OpenAI’s $880 billion valuation. The traffic data measures consumer-facing usage, not enterprise deployments or API calls.
