ChatGPT Drops Below 50% Market Share for First Time: What the New AI Landscape Changes

Friends, sharing an AI update: Sensor Tower data shows ChatGPT’s share has fallen below 50% for the first time.

ChatGPT remains the leader at ~46.4% with 1.1B monthly users; Gemini grows to 27.7%, Claude to 10.3%.
Users are switching assistants more frequently—events like OpenAI’s Pentagon deal triggered unsubscribe spikes.
Monetization is accelerating: H1 2026 projects ~2.3B downloads and $4.2B in spend; ads reach ~17% of ChatGPT daily users, while Claude has a high paid-subscription rate (~13%).
Why it matters: shifting shares and a revenue focus reshape development and integration priorities.
Who will win the next assistant race?
