Gemini losing market share to ChatGPT and Claude, data shows

Three independent data sources, Pangram, Similarweb, and OpenRouter, show Google's Gemini losing AI market share. Pangram recorded a drop from 12% to 1.9%, while OpenAI holds over 50% and Anthropic grew from 4.3% to 14.9%.

Why it matters: Multiple independent measurements agreeing is a stronger signal than any single report, and Anthropic's near-tripling of share is arguably the more striking half of this story alongside Gemini's decline. It's a real shift in the competitive landscape worth tracking against Google's own usage claims, like Gemini's reported 1 billion monthly users.
