The enduring historical superlative is outdated because Threads later reached 100 million registered users in five days. Those measurements are not perfectly equivalent, but the claim supplies no qualification preserving ChatGPT’s former record.\n\nCaveats\n\nThe 100 million figure was a third-party estimate, not a confirmed OpenAI user count.\n\nChatGPT held the widely reported adoption record in January 2023, not indefinitely.\n\nComparisons with Threads mix monthly active users with registered-user or signup counts.", "url": "https://wpnews.pro/news/chatgpt-reached-an-estimated-100-million-monthly-users-in-two-months", "canonical_source": "https://isthisbs.org/tech/chatgpt-s-growth-to-100-million-monthly-users-within-two-was-e297e1e3/", "published_at": "2026-09-07 11:26:03+00:00", "updated_at": "2026-09-07 14:26:30.284176+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products"], "entities": ["ChatGPT", "OpenAI", "Threads", "Meta", "Lenz"], "alternates": {"html": "https://wpnews.pro/news/chatgpt-reached-an-estimated-100-million-monthly-users-in-two-months", "markdown": "https://wpnews.pro/news/chatgpt-reached-an-estimated-100-million-monthly-users-in-two-months.md", "text": "https://wpnews.pro/news/chatgpt-reached-an-estimated-100-million-monthly-users-in-two-months.txt", "jsonld": "https://wpnews.pro/news/chatgpt-reached-an-estimated-100-million-monthly-users-in-two-months.jsonld"}}
