OpenAI now estimates its advertising business at $1 billion in annual revenue.

OpenAI has announced that its advertising business related to ChatGPT has reached an annualized revenue run rate of $1 billion. This figure represents the projected yearly earnings based on current monthly performance, multiplied by twelve. The company described this milestone as evidence of a functioning “diversified business model,” which includes subscription income, enterprise offerings, and usage-based API access. The achievement is particularly notable given that OpenAI’s advertising initiative within ChatGPT is less than 200 days old. The company began testing ads inside ChatGPT in the United States in early February 2026. On Monday, it expanded the program to include Europe, India, the Middle East, and North Africa. Initially, OpenAI had estimated the annual ad revenue would reach $2.5 billion, though whether that target will be met remains uncertain. The run rate does not reflect actual annual revenue yet but serves as a projection based on current trends. Since March 2026, the anticipated annual ad revenue has grown from approximately $100 million to $1 billion. This means the value has increased tenfold over just a few months. The rapid growth highlights the potential of the advertising segment within OpenAI’s broader strategy. On Monday, OpenAI launched self-service access through its Ads Manager in India, Europe, the Middle East, and North Africa. Marketers can now create campaigns directly using the platform without needing assistance from OpenAI’s sales team. These advertisements appear to users on the free tier and the more affordable “Go” plan. According to OpenAI, these user groups make up the majority of the more than 1 billion weekly active ChatGPT users. Subscribers to the higher-tier plans, Plus, Pro, Business, Enterprise, and Education, do not see ads. In terms of data privacy, OpenAI emphasizes that ads are clearly labeled as “Sponsored” and should not influence the responses generated by ChatGPT. The company follows a similar approach to other major advertisers, using the context of ongoing conversations to display relevant ads. Depending on the region and user settings, additional aspects of ChatGPT usage might be considered to tailor advertisements further, such as past topics and interests of the user. Technically, OpenAI employs a cost-per-click (CPC) model with bid optimization focused on results. Tools such as a tracking pixel and a conversions API are available for measuring success. The platform also supports product feeds, geographic targeting, and custom audiences. These features aim to provide marketers with flexibility and precision in their advertising efforts. OpenAI's expansion into new markets and the introduction of self-service tools indicate a strategic push to scale its advertising operations rapidly. The company appears to be positioning itself as a competitive player in the digital advertising space, leveraging its large user base and advanced AI capabilities. With continued growth in both user engagement and advertiser participation, the future trajectory of OpenAI’s advertising business could have significant implications for the broader tech industry.
