ChatGPT Market Share Drops Below 50% Amid Rising Competition from Gemini and Claude
OpenAI's ChatGPT remains the leading AI assistant with over 1.1 billion monthly users, but its market share fell below 50% for the first time in early 2026, reaching 46.4% by May. Competitors like Google's Gemini and Anthropic's Claude have gained ground, holding 27.7% and 10.3% market shares respectively. Claude also generates higher revenue per user than ChatGPT. User shifts have been influenced by features, pricing, and OpenAI's partnership with the US Department of Defense, which coincided with increased uninstalls. Despite this, the overall AI app market continues to grow globally.
