OpenAI Expands ChatGPT Ads to 89 Markets

OpenAI on October 21, 2026 expanded ChatGPT advertising to 26 more countries, reaching 89 markets. Ads run for Free and Go users only; Plus, Pro and Enterprise stay ad-free. More than 100,000 advertisers have run campaigns. The ad business hit a $1 billion annualized revenue run rate in August, up from $100 million in March. Named markets include Argentina, Chile, Colombia, Peru, Nigeria, South Africa, Serbia, Ukraine, Cambodia, Bangladesh and Pakistan. Contested: No factual dispute appears in the rated coverage. OpenAI says ads will be labeled, kept separate from chatbot answers, will not influence responses and will not expose user conversations to advertisers. It plans more ad formats, measurement tools and buying options. The step comes as OpenAI and rival Anthropic prepare for possible public listings, with executives indicating a 2027 listing is under consideration.
