ChatGPT ads run on the Free and Go tiers only. Every paid tier is ad-free, and free users can trade ads away for fewer daily messages.
Ads appear below responses and carry a "sponsored" label. The rollout began in the US and has moved market by market since.
OpenAI buys are placed through its Ads Manager at ads.openai.com. The self-serve beta opened to every US business in May 2026, with no minimum spend.
The policy has moved too. Health and finance advertisers gained a case-by-case route in April 2026, while political ads stay banned.
The log below is every dated step, each linked to its entry and primary source on our ChatGPT tracker.
