OpenAI's ChatGPT Ads Hit $1 Billion Run Rate in Under 200 Days

OpenAI announced that its advertising business within ChatGPT has reached an annual run rate of $1 billion, less than 200 days after the company began its first ad tests. At the same time, OpenAI opened a self-serve advertising platform for marketers in Europe, India, and the Middle East and North Africa.

The ads appear for users on the free version of ChatGPT and on the cheaper Go subscription plan. OpenAI says the ads are clearly labeled, kept separate from how the chatbot generates its answers, and that advertisers have no visibility into users' private conversations with the assistant.

Pace of growth

The scale of the growth is, according to figures cited by Forbes, unusually fast for a brand-new business line. ChatGPT ad revenue jumped from $100 million in April to $1 billion in August, averaging roughly $83 million a month over that stretch. To hit the $2.5 billion year-end target, OpenAI would need to generate more than $540 million a month in the fourth quarter.

The company has set an even more ambitious long-term goal: $100 billion in ad revenue by 2030. Hitting that mark would require sustaining a compound annual growth rate of nearly 190 percent for several more years, which some analysts view as a highly optimistic scenario.

Geographic expansion

Previously, self-serve ad buying in ChatGPT operated mainly in the United States. Starting August 31, OpenAI is opening that model to small and medium-sized businesses in 31 European countries, as well as in India and the Middle East and North Africa region. At the same time, the company is expanding partnerships with major ad agencies, including WPP and Omnicom, serving both global brands and smaller local advertisers.

Financial backdrop and IPO

Advertising is becoming a third major revenue pillar for OpenAI, alongside enterprise contracts and consumer subscriptions, and API usage billing. The company says it has about 1 billion weekly active users, most of them on the free version of ChatGPT or the cheaper Go plan, giving it a massive base to monetize through advertising without raising subscription prices.

The growth of the ad business coincides with OpenAI's preparations for an initial public offering. The company has already filed the relevant paperwork, with its valuation estimated at $852 billion and a stock market debut expected in 2027 or sooner. Diversifying revenue sources, including the contribution from ads, is meant to reassure future investors that OpenAI is not solely dependent on subscription fees and large corporate contracts.

What it means for advertisers

For businesses, this opens a new channel to reach users at the moment they're using an AI assistant for specific tasks, from shopping to trip planning. The self-serve model, now available in Europe too, lowers the barrier to entry for smaller businesses that previously had no direct access to buying ChatGPT ads and had to go through large agencies.

For Polish advertising and marketing firms, this means keeping an eye on a new ad format competing for budgets with Google Ads and Meta Ads. The pace of OpenAI's ad revenue growth suggests that in coming quarters ChatGPT could become a genuine third advertising platform alongside the existing giants, including for European clients using the self-serve dashboard.
