Confirmed
OpenAI moves every ChatGPT Ads campaign to a seven-day average daily budget starting today
OpenAI's Ads Manager help center confirms that starting July 27, 2026, daily budgets become a seven-day rolling average rather than a fixed daily cap: spend can run up to double the budget on a given day, capped at seven times it per week, with no advertiser action required. OpenAI's advertiser email, quoted independently by Search Engine Roundtable and Search Engine Land, also details conversion-optimized (oCPC) bidding, geo-exclusion targeting, a Bulk API, and refreshed product-feed ads showing price and star ratings.
In plain termsYour daily ad-spend limit on ChatGPT is no longer a hard per-day ceiling; OpenAI now averages it out over a week, so some days can cost twice your set budget as long as the week nets out even.
Why it mattersAdvertisers who read a daily budget as a hard per-day ceiling will see individual days run up to double that amount, and the new product-feed ad format puts feed data quality on display inside the ad unit itself.
Our takeI argued in 'Conversational ads converge' that Amazon, Google, and OpenAI had all converged on one mechanic: the model writes ad copy from the merchant's feed instead of advertiser-authored creative. The refreshed product ad format here, showing price and star ratings pulled straight from the feed, is that same mechanic landing as a literal ad unit, so a thin or stale feed now caps what the ad itself can show, not just what a shopping listing says.
