Europe: the current status
OpenAI announced on August 18, 2026 that ChatGPT Ads would expand into 31 European markets, including Germany, France, Spain, Italy and the Netherlands. At first, advertisers had to work through the sales team and partners. The official August 31 update says self-service sign-up through Ads Manager is now available in all 31 markets. Do not treat that opening as a future event.
Brazil was already in the pilot
Brazil is not one of the European countries, but OpenAI confirmed on August 11 that ChatGPT Ads had launched in Brazil, the United Kingdom, Mexico, Japan and South Korea. Check account eligibility and local features in Ads Manager before planning spend.
Audience, privacy and measurement
OpenAI says ads appear for Free and Go users, while Plus, Pro and Enterprise remain ad-free. Ads are labeled and separate from answers; advertisers do not see conversations. The platform describes CPM/CPC bidding, conversion optimization, geo-targeting, custom audiences, Pixel and Conversions API. Availability does not prove incremental audience or ROI: compare qualified visits, events and leads using UTMs, not impressions alone.
From interest to a useful landing page
A sensible test starts with a clear user-intent hypothesis and a landing page that answers that question. Measure the path through the commercial conversation. See Max Assistant's AI for business approach.
