ChatGPT Ads in 2026: where it is available and how to start advertising

OpenAI started showing ads inside ChatGPT in February 2026 and within a few months took them to dozens of markets. It is a new channel with little competition so far, and it pays to understand how it works before investing.

How ads in ChatGPT work

The test began on 9 February 2026 in the United States, with adult users on the Free and Go plans. According to OpenAI, ads are clearly labelled and separated from the answer, they do not influence what ChatGPT replies, and advertisers do not get access to conversations.

• They are shown on the Free and Go plans. Plus, Pro, Business, Enterprise and Education have no ads.
• They are not shown to accounts identified as belonging to users under 18.
• They are matched to the topic of the conversation: if someone asks for recipe ideas, the answer may be followed by an ad for a grocery delivery service.
• Users can manage ad personalisation or dismiss ads.

Where it is available today

After the United States, the channel opened in stages. Since 21 October 2026 you can advertise from 89 countries across the Americas, Europe, the Middle East, Africa and Asia-Pacific. The full list, and how to check the up-to-date version, is in ChatGPT Ads: which countries it is available in.

What about Argentina and the rest of Latin America

Since 21 October 2026, advertising in ChatGPT is available in Argentina and 13 other countries in the region, alongside Mexico and Brazil. The rollout is gradual: ad volume is limited at first.

For self-serve buying, the billing entity must be based in an available country, and an Argentine company now qualifies. What changes for a local brand and how to start is covered in ChatGPT Ads launches in Argentina.

How to get ready to advertise

1. Decide which live markets you sell in or want to sell in.
2. Check that your site clearly answers what your customer asks before buying: price, shipping, terms and differentiators.
3. Make sure conversions are measured properly, both on your site and in your CRM.
4. Separate traffic arriving from AI assistants in GA4 so you can compare it with the rest of your channels.
5. Start with a limited test budget and a concrete objective.

This channel is opening market by market: whoever arrives with the structure ready makes the most of the first months, while competition is still low.
