About this data
This page compiles published estimates of ChatGPT Search adoption and its position relative to traditional search, drawing on First Page Sage's Q2 2026 market-share report, the Similarweb 2026 AI Search report (via Digital Applied), and analyses from Sedestral and Exposure Ninja.
The AI Behavior Index is the research arm of OneChat AI, an integrated multi-model AI platform. We compile and analyze data from primary research sources to make AI adoption and market trends more accessible to journalists, researchers, and decision-makers.
Why "17% of queries" and "80% market share" coexist: they measure different universes. ChatGPT's ~17% is its share of all global digital queries (search engines + AI assistants combined); the often-cited ~77–80% figure is ChatGPT's share within the AI-chatbot category only. And critically, Google's share falling in relative terms does not mean Google shrank — total search volume grew ~26% globally, so AI captured new query demand rather than simply taking Google's.
Methodology notes: query-volume estimates are panel-modeled (Similarweb) and carry wide error bands — hence the 250–500M weekly range, shown here at its midpoint. Query-share figures blend primary disclosures with secondary analysis and are best read as approximate. Zero-click percentages come from field measurements and vary by query type. The "AI-driven search share over time" series uses disclosed annual anchors with directional interpolation between them.
