ChatGPT Falls to 57% Share; Gemini Hits 25%, Claude Nearly Triples
Similarweb traffic data shows ChatGPT's consumer AI market share has dropped from approximately 77% to 57%. Gemini surged to roughly 25% share—driven not by users switching, but by Google embedding Gemini into surfaces users already use: Search, Gmail, Docs, Android, Chrome, and Workspace. Claude's share nearly tripled to approximately 6% in a single month without equivalent distribution infrastructure, interpreted by analysts as product-pull rather than funnel-push. DeepSeek, Grok, Copilot, and Perplexity each remain below 4%.
Why It Matters
The structural split is now visible: Gemini grows through Google's distribution moat; Claude grows through user preference despite no comparable surface area. ChatGPT is defending a shrinking majority. For any platform building on top of AI providers, model selection is now a strategic positioning decision, not just a capability choice.
