ChatGPT Ads Swaps Bid Caps for Average Cost Targets, What to Check

What Changes When Bid Caps Become Averages?

Search Engine Journal's Matt G. Southern explains that ChatGPT Ads is replacing Max Bid and Max CPC with Target CPA and Target CPC, average cost goals rather than per-auction ceilings. The piece walks through the timeline: new conversion and click campaigns get the targets from November 9, legacy API values start acting as averages from November 18, and the old fields are deprecated on January 1, 2027. It also covers the delivery risk when a target sits below recent performance.

If you buy media on ChatGPT Ads, or run integrations through an API partner, this is a practical checklist rather than a press release. The reporting on how the final winning bid sets the price, and on documentation changes that happened after the author first read the pages, is worth knowing before you plan budgets. Performance marketers and paid social leads should read it now, and agency teams managing client accounts should share it with whoever owns the bidding settings.
