ChatGPT reached one billion users with seven months' delay, first sign that even the leader of consumer AI has difficulty achieving its goals.
ChatGPT reached one billion weekly active users, according to internal OpenAI data which presented The InformationThe company estimated to reach the milestone by the end of 2025, however finally touches it in mid-2026, with a seven-month delay.
The delay does not reduce the size of the achievement particularly. ChatGPT is one of the digital products developed faster than any other on this scale, reaching there in less than four years. About one in eight internet users uses it every week, for everything, from code to medical questions.
His course has been rapid. From about 400 million weekly users in February 2025, Sam Altman posted the number to 800 million in October, while in February 2026 ChatGPT exceeded the number of 900 millionIn June, in fact, the application was made faster than any other to one billion monthly users.
The target lost by seven months is perhaps the most revealing number. It is the first clear sign that even OpenAI, the undisputed leader in consumer AI, is now having difficulty responding to its own predictions. Growth on a basis of a billion users is much harder to maintain than on a base of a hundred million.
Competition does not facilitate the situation. Google's Gemini, Anthropic's Claude and a wave of cheaper Chinese models gradually erode OpenAI's lead, which is no longer as large as a year ago. The company continues to lead with ease, but the lead seems to be preserved rather than widened.
The number of users is not just a matter of prestige. Supports valuation behind path of OpenAI to IPO, as well as the argument that consumer interest, and not only corporate contracts, will fund the enormous needs in computing power.
