ChatGPT has doubled its weekly active users to 200 million

ChatGPT now has 200 million weekly active users, according to OpenAI. That represents a doubling of the weekly audience of 100 million the company announced last November. A representative from the company told Engadget that API usage has also doubled since the July release of GPT-4o mini.

User numbers aren’t the only big growth OpenAI has seen over the past year. CEO Sam Altman reportedly told employees this summer that the company’s annualized revenue — which takes a monthly revenue figure and stretches it out over a whole year — had reached $3.4 billion, up from $1.6 billion at the end of 2023.

Separately from today’s usercount announcement, The Wall Street Journal reported that Apple, Nvidia and Microsoft are in talks to invest in a new fundraising round for OpenAI. The only detail the report had about the scale of this funding round was that it would push OpenAI’s valuation above $100 billion.

Microsoft has invested $13 billion into the AI business since 2019, while Apple revealed that ChatGPT will form a large part of its upcoming Apple Intelligence push. Both Microsoft and Apple gave up their seats on OpenAI’s board of directors this summer after the European Commission raised antitrust concerns about the businesses’ close relationships.
