UBS analysis based on Similarweb data placed ChatGPT at roughly 100 million monthly active users in January 2023, about two months after its November 30, 2022 launch. However, the figure was not an official OpenAI count, and extensive media repetition largely traces back to that same underlying analysis.\n\nCaveats\n\nThe 100 million figure was an analyst estimate, not an official OpenAI user count.\n\nMany reports repeat the same UBS/Similarweb analysis rather than providing independent measurements.\n\nThe underlying metric was monthly active users, not necessarily 100 million registered individuals.", "url": "https://wpnews.pro/news/chatgpt-had-an-estimated-100-million-monthly-active-users-by-january-2023", "canonical_source": "https://isthisbs.org/tech/chatgpt-reached-100-million-monthly-users-within-two-months-9f43a2fe/", "published_at": "2026-09-07 11:25:27+00:00", "updated_at": "2026-09-07 14:26:33.045568+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products"], "entities": ["ChatGPT", "OpenAI", "UBS", "Similarweb"], "alternates": {"html": "https://wpnews.pro/news/chatgpt-had-an-estimated-100-million-monthly-active-users-by-january-2023", "markdown": "https://wpnews.pro/news/chatgpt-had-an-estimated-100-million-monthly-active-users-by-january-2023.md", "text": "https://wpnews.pro/news/chatgpt-had-an-estimated-100-million-monthly-active-users-by-january-2023.txt", "jsonld": "https://wpnews.pro/news/chatgpt-had-an-estimated-100-million-monthly-active-users-by-january-2023.jsonld"}}
