OpenAI is expanding advertising on ChatGPT to 26 more countries, bringing the total to 89, as it builds out its ad business ahead of a potential IPO. The company said in August that the business had reached an annualized revenue run rate of $1 billion. Microsoft (NASDAQ:MSFT) held a roughly 27% stake in OpenAI after its recapitalization in October 2025.
The expansion adds 14 more Latin American countries, including Argentina, Chile, Colombia and Peru, following launches in Mexico and Brazil, along with markets across Europe, the Middle East, Africa and Asia such as Nigeria, South Africa, Ukraine and Pakistan. More than 100,000 advertisers have run campaigns since OpenAI began testing ChatGPT ads in the U.S. earlier this year. Ads appear only on the Free and Go plans, while Plus, Pro and Enterprise subscriptions remain ad-free.
Advertisers in the new markets can buy through technology partners or use self-service access through Ads Manager. In September, OpenAI introduced AI-powered tools for advertisers and began testing business-sponsored agents with select U.S. advertisers.
