OpenAI said Monday that advertising on ChatGPT has reached a $1 billion annualized revenue run rate less than 200 days after launch, giving the artificial intelligence company a rapidly expanding source of income as it prepares investors for a potential initial public offering.
The milestone highlights the speed at which OpenAI is attempting to diversify its business beyond subscriptions, enterprise contracts and usage-based API revenue. The company said advertising now represents a “material share of the business,” although it did not disclose the actual revenue generated by the ad operation over the period.
“Advertising is one pillar of OpenAI’s diversified business model, alongside consumer subscriptions, enterprise offerings, and usage-based APIs,” the company said.

An annualized revenue run rate is based on current or recent revenue levels projected over a full year. It does not mean OpenAI has already generated $1 billion in advertising revenue since launching the service.
The rapid expansion of advertising could become an important part of OpenAI’s investment story as it prepares for a possible IPO. The company is facing enormous computing and infrastructure costs as it expands its AI models and services, making the development of multiple high-margin revenue streams increasingly important to its long-term financial model.
OpenAI’s move into advertising was once viewed as unlikely. Chief Executive Sam Altman had previously expressed reservations about introducing ads into AI products, arguing that the model could create incentives that undermine the user experience.
“Ads plus AI is sort of uniquely unsettling to me,” Altman said at an event at Harvard University in May 2024. “I kind of think of ads as a last resort for us for a business model.”
The company has since moved ahead with advertising as it seeks to turn ChatGPT’s enormous consumer audience into a larger commercial opportunity.
The expansion puts OpenAI in competition with an established digital advertising industry dominated by companies such as Alphabet and Meta Platforms. ChatGPT, however, gives OpenAI access to a different type of consumer interaction, with users directly communicating their needs, interests, and intentions to an AI system.
That creates significant potential value for advertisers, but it also raises questions about how commercial messages can be integrated without undermining user trust.
Anthropic, OpenAI’s rival, has repeatedly attacked the advertising model. Its Super Bowl campaign mocked OpenAI’s decision by depicting an AI assistant turning user conversations into opportunities to deliver emotionally targeted advertisements.
Altman described the campaign as “funny” but “clearly dishonest.”
The controversy illustrates the central challenge OpenAI faces as it commercializes ChatGPT: advertising could provide a substantial new revenue stream, but poorly designed ads could weaken the trust that has helped make the chatbot one of the world’s most widely used AI products.
OpenAI said ChatGPT advertising is now available in more than 40 countries. On Monday, it is also launching a self-service advertising platform across India, Europe, the Middle East and North Africa, allowing businesses to participate in the system without relying entirely on direct sales arrangements.
The company said its next phase will include more markets, advertising formats, campaign objectives, purchasing options and measurement tools. It also plans to explore ways for businesses to interact with consumers more directly within ChatGPT.
IPO Puts Pressure on Growth And Monetization
The advertising milestone comes as OpenAI weighs a public listing that could take place as early as this year, although the company has indicated that an IPO is not imminent.
The company is under increasing pressure to demonstrate that its extraordinary user growth can translate into sustainable revenue and eventually profits. AI development requires substantial spending on computing infrastructure, chips, data centers and model training, making revenue diversification a central part of the business case for investors.
OpenAI has also been narrowing its product focus. In recent months, the company has shut down or scaled back ventures including Sora, its short-lived short-video-style AI application, as it concentrates resources on its core AI business. At the same time, OpenAI has experienced senior executive departures, including Chief Operating Officer Brad Lightcap, adding another layer of scrutiny as the company moves toward its next stage of growth.
The $1 billion advertising run rate therefore represents more than a milestone for a new business line. It provides OpenAI with evidence that ChatGPT can generate commercial value from its massive consumer audience without relying exclusively on subscription payments.
However, analysts consider OpenAI’s ability to expand advertising while preserving user trust and maintaining strong growth across its other businesses as the bigger test. If it succeeds, some believe that advertising could become a significant financial pillar alongside subscriptions, enterprise software and APIs, strengthening the company’s revenue profile ahead of a potential public-market debut.
