ChatGPT Falls to 54.7%, Claude Surges 306%

MARKET SHARECHATGPTCLAUDE

ChatGPT is still dominant, but the AI chatbot market is fracturing. New Momentic data shows Claude grew 306% in one quarter, from 203M to 824M monthly visits. ChatGPT slid from 76.5% to 54.7% share in 15 months.

Claude had 1.4% web-visit share in February 2025. By April 2026 it reached 8.2%, with 12.5% in the US specifically. The 306% quarterly growth is off a small base, but the direction has been consistent for four consecutive quarters.

Key engagement signal: Claude has the lowest bounce rate of the seven tracked chatbots (26%), and the second-highest pages per visit (4.34). Users who find claude.ai stay and work. DeepSeek's spike to 12% in February 2025 faded; Claude's rise has compounded steadily since Q2 2025.

ChatGPT is still five times Claude's size by web traffic. These numbers are consumer web visits, not API or enterprise revenue. But consumer web fracturing is historically the leading signal that enterprise preference follows, usually 12-18 months later.

full brief & sources

⚡ Why this matters

  • Web traffic share is a leading indicator of developer mindshare - when developers shift their personal usage, enterprise purchasing follows within 12-18 months
  • Claude's lowest-bounce-rate signal (26%) suggests product-market fit: users arrive knowing what they want and complete tasks, not just experimenting
  • ChatGPT's decline from 76.5% to 54.7% in 15 months is historically fast market share erosion for a category-defining product - comparable to IE6's decline after Firefox

🔍 What happened

  • Data source: Momentic analysis of Similarweb estimates, published June 2 2026, measuring global web visits to AI chatbot interfaces
  • ChatGPT: 54.7% share (down from 76.5% in February 2025)
  • Gemini: 27.4% share (up from 5.6% in February 2025, boosted by Google Search integration)
  • Claude: 8.2% global share, 12.5% in the US - 306% growth in Q1 2026 (203M to 824M monthly visits)
  • Claude engagement stats: 26% bounce rate (lowest in set), 4.34 pages/visit, roughly 7-minute average session
  • The 7-chatbot tracked set: ChatGPT, Gemini, Claude, Copilot, DeepSeek, Grok, Perplexity

💬 Smart takes

  • Tyler Einberger (Momentic): 'Claude's explosive 306% QoQ growth - from 203M to 824M monthly visits - signals a rapidly expanding user base, not just a niche audience for technical users.'
  • Skeptic read: Gemini's 27.4% share is inflated by Google Search steering - it's distribution, not product-market fit. Claude's 8.2% is more organically earned. But 8.2% is still niche compared to what Anthropic needs for its revenue targets.

🧭 Where this goes

  1. LikelyClaude crosses 15% US web-visit share by Q3 2026, coinciding with Apple Intelligence's Claude option rolling out to iOS 27 users
  2. LikelyChatGPT stabilizes around 45-50% as OpenAI pushes enterprise harder and accepts lower consumer share as the tradeoff
  3. PossibleGemini's Google Search distribution advantage diminishes as EU antitrust pressure forces default AI unbundling, narrowing the gap
  4. Wild CardAnthropic achieves parity with ChatGPT in US web traffic before the end of 2026, driven by iOS 27 Extensions distribution

🥄 The Spoon Take

The market that looked like OpenAI's permanent monopoly 18 months ago is now a three-way race. Claude's growth is sticky - low bounce rates, long sessions, steady compounding. The iOS 27 Extensions distribution isn't in these numbers yet. The next report will be significantly different.

🤔 Pushback

Web visits measure awareness and experimentation, not monetization - Claude's revenue share is still far below its traffic share, and that gap is what matters for Anthropic's path to sustainability.
