OpenAI has expanded advertising inside ChatGPT to 26 additional countries, raising the platform’s stated availability to 89 markets. The rollout, announced on October 21, 2026, is concentrated in Latin America, Africa and Asia, and it arrives roughly eight months after the company began testing ads in the United States. For Spanish users, the service reality is unchanged: Spain entered the European ad rollout in August, and European Economic Area rules still prevent personalized advertising by default.
Key takeaways:
- More markets: OpenAI added 26 countries, for a total of 89 where ChatGPT Ads is available, though it named only 11 of the new entrants.
- Advertiser milestone: More than 100,000 advertisers have run campaigns since launch, a cumulative figure that comes as ChatGPT reaches over 1.2 billion weekly users.
- Limited tiers: Ads remain confined to Free and Go plans; Plus, Pro, Enterprise, Business and Edu subscriptions stay ad-free.
- Privacy unchanged: The expansion does not alter targeting rules, and the EEA and Switzerland still do not receive personalized ads by default.
A wider map, with gaps in transparency
OpenAI has not disclosed the full list of 26 new markets. It named 11: Argentina, Chile, Colombia and Peru in Latin America, plus Nigeria, South Africa, Serbia, Ukraine, Cambodia, Bangladesh and Pakistan elsewhere. That leaves 15 countries unidentified, and the company has not supplied per-country activation dates. The only European additions named are Serbia and Ukraine, both outside the European Union. The broader sequence is clearer: the U.S. pilot began on February 9, Mexico and Brazil followed in August, 31 European markets went live on August 24, India arrived late that month, and Southeast Asia and Taiwan were added in September.
A crucial distinction is that 89 is the number of countries where the advertising platform is available, not a guarantee that every user in the 26 new markets will see ads immediately. OpenAI has framed the expansion as commercial availability rather than a switch that flips everywhere at once.
Advertiser growth and the monetization clock
OpenAI says more than 100,000 advertisers have run campaigns on ChatGPT. The number is cumulative, covers the whole period since launch, and comes without an earlier comparison from the company. Industry coverage nonetheless reported that OpenAI had cited roughly 60,000 advertisers only two weeks before the update, implying a sharp acceleration; trade projections cited in that coverage see 500,000 advertisers by next March and 1 million by next September. OpenAI also says ChatGPT serves more than 1.2 billion weekly users and that “a little more than eight months” have passed since the ad product launched.
The financial context is equally important. OpenAI declared a $1 billion annualized revenue run rate for advertising in August, a figure that measures pace rather than full-year revenue. Ads appear only on Free and Go plans; Plus, Pro, Enterprise, Business and Edu remain without advertising, according to OpenAI’s help center. Campaigns are bought through technology partners or self-service in Ads Manager, and the roadmap promises additional formats, objectives, buying options and measurement capabilities, without dates.
Privacy, formats and competitive pressure
The announcement does not change ad targeting or privacy policy. OpenAI repeated its standard commitments: conversations stay private from advertisers, customer data is not sold, ads are labeled and separated from answers, and advertising does not shape ChatGPT’s responses. In the EEA and Switzerland, personalized ads are off by default; turning off personalization does not remove ads, it only stops the system from using previous chats to choose them.
“We keep conversations private from advertisers and do not sell customer data,” OpenAI said, adding that ads are “clearly labeled and separate from responses” and that “advertising does not influence the answers ChatGPT gives.”
Format experimentation is moving in parallel. On October 5, OpenAI began testing labeled image ads alongside generated images in the United States with a small group of advertisers, while Plus and Pro users remain exempt. It has also added third-party measurement and attribution partners, including DoubleVerify and Integral Ad Science, with brand-suitability work designed to run without access to user conversations. Competitive pressure is mounting: Anthropic has committed to keeping Claude ad-free, Google has denied rumors of ads in Gemini, and Netflix already reaches 250 million ad-supported viewers each month. OpenAI’s challenge is to prove that conversational advertising can scale without eroding the trust that made ChatGPT a mass-market product.
What matters most is speed. Moving from a U.S. pilot to 89 markets and 100,000 advertisers in eight months is not explained by user demand alone; it reflects a revenue line that can support a company preparing for public-market scrutiny. The missing metric is user response: OpenAI has not said how many people disable personalization or downgrade plans to avoid ads. Until it does, the 89-market milestone measures commercial reach, not consumer acceptance.
