Context & Analysis

The survey covered June 2024 through May 2026 and tracked six services: ChatGPT, Gemini, Claude, Microsoft Copilot, Perplexity AI, and Agent i. Agent i was counted only for web browser use, and Gemini data had some limitations, so those figures may understate actual usage. The user numbers are expanded estimates that include duplicate counts across mobile apps and web browsers, and desktop apps were excluded from the tally. Valuence concluded that ChatGPT is leading the market while other services are rapidly gaining ground, and it noted that heavy usage is spreading mainly among people in their 20s and 30s, for whom these tools are becoming infrastructure for gathering information and doing work.
