OpenAI announced this week that ChatGPT advertising is rolling out across 31 European markets starting August 24. The list includes Germany, France, Spain, Italy, Poland, Austria, Switzerland, the Benelux countries, and Scandinavia — the core of European e-commerce revenue in a single move.
Five days from now, ChatGPT Ads will be available in 35 countries worldwide. Six months ago, they were US-only.
What's actually rolling out
ChatGPT Ads will appear for users on the Free and Go plans in all 31 markets. Plus subscribers (€23/month in Europe) and Pro subscribers (€229/month) won't see ads. That's the same tier structure OpenAI used for the UK launch in June and the five-country expansion in August — Mexico, Brazil, Japan, and South Korea.
The ads are visually separated from ChatGPT's answers, clearly labeled as sponsored and not woven into the response. OpenAI VP of Ads Dave Dugan confirmed to Adweek that chat histories won't be shared with advertisers and that conversation data won't feed targeting systems.
Access for advertisers won't be instant. Based on the US and UK rollout pattern, there will be a managed-partner phase before self-serve Ads Manager opens in these markets. Register at openai.com/advertisers now. The pipeline filled slowly in the US, but Europe's combined market size means capacity will fill faster.
The GDPR situation across 31 markets at once
If you followed the UK launch in June, you know OpenAI rejected "legitimate interest" as a legal basis for personalized advertising and required explicit opt-in instead. That ruling applies to the EU member states in this batch too — with the added variable that enforcement intensity differs by country.
Germany and France have the most active data protection authorities in Europe. Both have a track record of treating ad tech consent more aggressively than OpenAI's US-market interpretation would assume. Austria, where NOYB's cases have produced the most GDPR ad tech case law, is also in this launch set.
This doesn't mean ChatGPT Ads in Europe won't perform. The UK pilot ran without enforcement incident, and Zalando's participation as launch partner showed that high-purchase-intent targeting works even with the consent layer in place. But it does mean two things:
Your European audience on ChatGPT will split between users who opted in (personalized ads) and users who didn't (contextual-only). You won't know your personalized-to-contextual ratio until the first weeks of campaign data arrive. And if you're building audience lists or lookalike segments for Europe, the data you seed them with needs to be consent-clean. ChatGPT won't be the liability — your upstream CRM and attribution stack will.
How this compares to the US rollout
The US launch started at roughly $60 CPMs in February, then dropped to around $25 by May when CPC bidding became available, according to Search Engine Land's reporting at the time. UK CPMs at launch tracked higher than the US floor due to lower inventory volume.
Expect a similar curve in Europe: elevated CPMs at launch for 10–14 days as inventory is thin, then compression as more advertisers enter through the managed pipeline. The floor will differ by country — German inventory won't price the same as Polish inventory.
Conversion rates in conversational ad placements don't map from search or social benchmarks. The intent signal is different: someone asking ChatGPT about running shoes is earlier in the funnel than someone searching "buy running shoes under €100." Build separate benchmarks. Don't carry your Meta or Google CPA targets into the first 60 days of European ChatGPT data.
What to actually do before August 24
If European revenue is a meaningful share of your business, register at openai.com/advertisers now. The managed-partner window is where early benchmarks get built, and first-mover data in a new market is worth something when you're eventually negotiating placements or talking to agencies about test budgets.
If Europe is marginal for you right now, wait 60 days. Watch four things:
- Published CPM data from early European advertisers (Adweek and Digiday will cover this)
- Whether self-serve opens before end of Q3 or slips into Q4
- How the consent opt-in rate affects your personalized-to-contextual ratio in target markets
- Whether German or French authorities raise any early enforcement concerns
This expansion is the moment ChatGPT Ads stops being a US/UK experiment and becomes a real line in global paid media planning. That doesn't mean you should allocate budget this week. It means you should know what it is before your agency brings it up in September.
If you want to know where your current European attribution stack has gaps before ChatGPT Ads becomes another channel to reconcile, Gromerce's free audit will surface them in about three minutes.
OpenAI built a meaningful ad platform in six months. Whether European advertisers can make it perform is the next question worth watching.
