OpenAI’s ChatGPT advertising business has reached a $1 billion annualized revenue run rate, a milestone the company hit in fewer than 200 days after launching ads in February 2026. For a company whose CEO once described advertising as a “last resort,” that’s a remarkably enthusiastic embrace of Plan B.
The ad rollout began with US testing in early 2026 and has since expanded to over 40 countries. OpenAI’s self-serve Ads Manager is now live for advertisers across India, Europe, the Middle East, and North Africa, with small and medium-sized businesses making up a meaningful chunk of the advertiser base. The company is targeting $2.5B in ad revenue by the end of 2026, while projecting over $40B in total annualized revenue by year-end.
From “last resort” to billion-dollar business
In 2024, Sam Altman was vocal about his distaste for mixing AI with advertising, flagging concerns about user trust and the ethical murkiness of ads influencing AI-generated responses. By January 2026, OpenAI had officially changed course, announcing plans for ads that would be “relevant, clearly labeled, and respectful of user privacy.” The company was in the middle of massive infrastructure spending, and subscription revenue alone wasn’t going to cover the compute costs of running one of the world’s most popular AI products, particularly with a reported IPO planned for 2027.
