ChatGPT Sees Majority Non-English Consumer Use

Editorial analysis: For practitioners, the shift to predominantly non-English usage changes evaluation priorities, localization requirements, and dataset composition for real-world deployments. According to OpenAI's Signals data, more than half of active ChatGPT users on individual consumer plans now predominantly use a language other than English (OpenAI, June 30, 2026). OpenAI reports that the most common non-English languages are Spanish, Portuguese, and Arabic, and that relative user growth has been fastest in Africa and Asia, with lower-HDI countries showing the largest relative increases (OpenAI Signals). The dataset described covers Individual plans (Free, Go, Plus, Pro) and explicitly excludes Enterprise, education, and Codex usage (OpenAI). Search Engine Journal summarizes these findings and highlights rapid growth in smaller languages such as Uzbek, Kazakh, and Burmese among languages with over 1 million users (Search Engine Journal).
