Eight months ago, putting ads inside ChatGPT sounded like a risky brand decision. Now it looks like a standard line of business. OpenAI announced that ChatGPT Ads is expanding to 26 more countries, bringing the total to 89, and that more than 100,000 advertisers have already run campaigns.
The new markets lean heavily toward emerging regions. Fourteen more Latin American countries are joining, including Argentina, Chile, Colombia and Peru, following earlier launches in Mexico and Brazil. The list also adds Nigeria, South Africa, Serbia, Ukraine, Cambodia, Bangladesh and Pakistan. This follows recent rollouts across Europe, Southeast Asia and Taiwan. The pattern is clear: OpenAI is not testing in a few rich markets and waiting. It is going wide, fast.
Access works two ways. Advertisers can buy through technology partners or use self-service through Ads Manager. That second option matters. Self-serve tooling is what let Google and Meta build huge long-tail businesses from small local advertisers, and OpenAI is copying that playbook. The company also says it plans more ad formats, objectives, buying options and measurement tools. Those gaps are real today. Advertisers used to Google’s conversion tracking or Meta’s targeting will find the early toolset thin.
The pitch is that ChatGPT catches people mid-decision. OpenAI’s example is a marathon runner planning race-week meals who gets nudged toward a grocery delivery service. That is the same intent-heavy territory search has owned for twenty years, but with a conversational twist. L’Oréal, quoted in the announcement, is already talking about moving from discovery to evaluation to agentic commerce, which hints at where OpenAI wants this to go: ads that lead straight to purchases made inside the chat.
Scale helps the argument. OpenAI says more than 1.2 billion people use ChatGPT each week. Even a small share of that attention is a serious ad inventory, and it gives Google, Microsoft and Perplexity something to worry about. Google is pushing ads into AI Overviews and AI Mode, so the fight over who monetizes AI answers is now direct.
There is also a plain financial reason. Running frontier models for a billion users is expensive, and subscriptions alone are unlikely to cover free access worldwide. OpenAI frames ads as the way to keep free and low-cost tiers alive. Ads appear only on Free and Go plans, while Plus, Pro and Enterprise stay ad-free. That is a sensible split, and it mirrors how streaming services tiered their products.
The risk is trust. OpenAI says conversations stay private from advertisers, customer data is not sold, ads are clearly labeled and separate from answers, and advertising does not influence what ChatGPT says. Those are strong promises. But they are self-reported, and users have little way to verify them. The first time someone suspects a recommendation was bought, the damage will be hard to repair. Search engines have lived with that suspicion for decades. A chatbot that people treat like an advisor may get less patience.
So is this noise? No. The country count is the least interesting number. What matters is that 100,000 advertisers signed up this quickly, which suggests demand is real. Watch for two things next: how good the measurement tools get, and whether OpenAI keeps the line between answers and ads clean once the pressure to hit revenue targets grows.
