Sensor Tower’s State of AI 2026 report says ChatGPT’s audience share slipped below 50% for the first time, while Google’s Gemini and Anthropic’s Claude continued to narrow the gap. The report points to Gemini’s default-app advantage and Claude’s growth from enterprise adoption as key drivers.
Why it matters
For readers tracking the AI market, the shift shows that user distribution is becoming less concentrated around one platform. That can matter for companies competing for consumer attention, app placement, and enterprise contracts, especially as AI tools become more integrated into everyday software and workflows.
ChatGPT remains the biggest AI chatbot, but its lead is shrinking. According to Sensor Tower’s State of AI 2026 report, ChatGPT’s audience share fell below 50% for the first time as rival assistants gained traction.
The report highlights two notable challengers: Google’s Gemini and Anthropic’s Claude. Gemini has benefited from being the default app on some devices, while Claude has expanded its presence in part through enterprise use, including adoption linked to government and defense contracts.

The findings also suggest that chatbot competition is moving beyond product awareness and toward distribution advantages. Default settings, workplace adoption, and platform access may play a larger role in future market share than brand recognition alone.
Sensor Tower’s report does not indicate that ChatGPT has lost its lead outright, but it does show that rivals are closing the gap faster than before. For the broader AI sector, that points to a more competitive landscape heading into 2026.
