ChatGPT's advertising business has reached a $1 billion annualized revenue run rate, OpenAI says, a mark the company reports hitting in under 200 days of selling ads. OpenAI credits the ad revenue with helping fund a free ChatGPT tier it says reaches more than 1 billion people each week.
OpenAI says ChatGPT ads now run in more than 40 countries, sold through its own team, agencies, and a partner network of more than 50 technology and measurement firms. It is opening self-serve buying through its Ads Manager to businesses in India, Europe, the Middle East, and North Africa, extending a tool it launched for small and medium companies in May.
The number shows how fast a company that spent its early years without ads has taken to the model that funds most of the consumer internet. OpenAI now treats an ad-supported free tier as core strategy rather than a stopgap, a route Google and Meta took years ago. It reaches AI chat with the same basic exchange: a person working through a software purchase, a loan, or a house move becomes an audience a marketer can pay to reach.
One caveat sits under the headline figure. An annualized run rate projects a recent stretch of revenue across a full year, so it describes a pace rather than money booked, and the number is OpenAI's own and unaudited. The company also highlights early advertiser wins, but those results come from OpenAI and its partners, not independent measurement.
The trade is sharper for a product people use as a sounding board. OpenAI says its system reads the current conversation to place a relevant ad and, depending on the country and a user's settings, can also draw on activity from the rest of someone's ChatGPT history. It says ads are labeled, kept apart from ChatGPT's answers, and barred from changing them, and that advertisers cannot see private chats. How clear that separation stays is the open question as OpenAI adds more native ad formats and new ways for businesses to reach customers inside the app.
