What exactly did OpenAI announce?
On 21 October 2026 OpenAI published that ChatGPT ads are reaching 26 more countries, taking the product to 89. The company says that since launching ads a little over eight months ago, more than 100,000 advertisers have run campaigns on the platform.
For Latin America the post is concrete: after Mexico and Brazil, ads reach 14 more countries in the region. The text only names Argentina, Chile, Colombia, and Peru; the rest have to be looked up in the help center (we cover that in the next section).
Three points from the post matter for deciding:
- Where they appear. Only on the Free and Go plans. Plus, Pro, and Enterprise remain ad-free.
- How they are bought. Through technology partners or self-service in Ads Manager.
- What OpenAI promises. That ads are “clearly labeled and separate” from the answers and that advertising does not influence what ChatGPT replies. Also that conversations are not shared with advertisers and that it does not sell user data.
OpenAI adds that the next phase will include new formats, objectives, buying options, and measurement capabilities. Read that the other way round too: today those options are more limited than what you are used to in Google or Meta.
Which Latin American countries can buy today?
OpenAI's Ads Manager availability page, checked on 23 October 2026, lists these countries in the region as available for self-service:
| Subregion | Countries with self-service available |
|---|---|
| North America and the Caribbean | Mexico, Puerto Rico, Dominican Republic |
| Central America | Costa Rica, El Salvador, Guatemala, Panama |
| South America | Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay |
That is 16 countries: Mexico and Brazil, plus the 14 new ones. Honduras, Nicaragua, and Venezuela are not on the list. Spain is available too, in case you sell on both sides of the Atlantic.
The condition most often missed is a different one: to use self-service, the legal entity advertising and being billed has to be in an enabled country. If your company bills from a country on the list but wants to advertise in another, or if an agency runs the account from outside, check this before planning. The list changes often, so check it the day you open the account.
Who sees the ads and who does not?
Ads only appear on the Free and Go plans. In its principles post of 16 January 2026, OpenAI had already said that Plus, Pro, Business, and Enterprise would carry no ads. Go is the low-cost plan, which on that date cost 8 dollars a month in the United States.
For a B2B company that has a direct consequence: someone using ChatGPT on a paid company account does not see your ads. If your typical buyer works at an organization that has already bought Business or Enterprise, you reach them on their free personal account, not when they research vendors from the work one.
OpenAI does not publish how many users there are per plan or per country, so nobody can tell you today what share of your market sees ads. Be wary of any figure that claims to.
There are more limits. In that same January post, OpenAI said that during the trial it would not show ads to accounts belonging to under-18s, nor near sensitive or regulated topics such as health, mental health, or politics. Also that users can turn off personalization and delete the data used for ads. If you sell into sectors like health, check carefully whether your topics fall outside.
Pay to appear, or earn the citation?
They are two different things, and mixing them leads to bad budget decisions.
| Ad in ChatGPT | Citation in the answer (AEO) | |
|---|---|---|
| Where you appear | Beside the answer, labeled as an ad | Inside the answer, as a source or recommendation |
| Who sees it | Only Free and Go users | Any user, including paid plans |
| How long it lasts | As long as you pay for the campaign | As long as your content remains the best source |
| How you get it | Budget and targeting | Clear, verifiable, well-structured content |
If OpenAI holds to what it promises, paying for ads does not improve your position in the answers. And the reverse: a company ChatGPT already cites does not need to buy an ad to be in that conversation.
Which is why the first step is not opening the ads account but knowing where you stand. If you do not know whether ChatGPT already mentions your brand, start with how to tell whether ChatGPT recommends your brand. And if you want to work on the organic side, the AEO guide for B2B companies explains where to start.
What to ask yourself before committing budget
A new channel is attractive for being new. Before testing it, answer these five questions honestly:
- Does your buyer research on free ChatGPT? If they decide from paid corporate accounts, the ad does not reach them.
- Can your legal entity buy? Check the country list and where you bill from.
- Are your current channels already working? If your Google or LinkedIn campaigns bring contacts who do not buy, one more channel multiplies the problem. We cover it in why your campaigns bring leads that do not buy.
- Can you measure what happens after the click? If your CRM does not record which channel each opportunity came from, you will not know whether the channel worked.
- How much are you willing to lose learning? A test in a new channel is a learning expense. Set a ceiling and a cut-off date before you start, with the same logic we use in how much to invest in Google Ads to start.
If you hesitate on two or more, the prudent move is to wait: the channel is not going anywhere, and OpenAI has already said more formats and more measurement are coming.
What to measure if you do test it
OpenAI says it is building more measurement capabilities, so do not expect today the level of detail from platforms with years in the market. What you can control is your side:
- Tag every link. Use your own UTM parameters so your analytics and your CRM separate this traffic from the rest.
- Measure opportunities, not clicks. In B2B a click is worth little. What matters is how many contacts reach a meeting and how many reach a proposal.
- Compare against a known channel. Put the cost per opportunity next to Google Ads or LinkedIn, over the same period.
- Look at contact quality. Check whether you are getting people from companies you can serve or consumers after something else.
- Cut on the date you set. Decide with CRM data, not with the impression that the channel is fashionable.
If you are not clear how your channels connect to your sales today, that map is what we review in a Digital Audit, before adding one more channel.
