ChatGPT Ads Retires Max Bid and Max CPC — Target CPA and Target CPC Take Over by January 2027
In short: OpenAI emailed ChatGPT Ads advertisers on 5 November 2026 to say it is replacing two bidding options: Max Bid becomes Target CPA (cost per action) for conversion campaigns, and Max CPC becomes Target CPC for click campaigns. The new options became available in Ads Manager on 9 November 2026, for new campaigns and for switching existing ones. Max Bid and Max CPC keep working until they retire on 1 January 2027, when any campaign still using them moves automatically to the new equivalent.
- Max Bid is being replaced by Target CPA: you set an average cost-per-conversion goal and the system bids toward it, instead of capping a maximum bid per auction.
- Max CPC is being replaced by Target CPC: the system can bid above or below your target in individual auctions to get as many clicks as possible within budget, instead of a hard per-click cap.
- "Maximize results" autobidding is simply being renamed "Intelligent bidding" — no functional change there.
- Target CPA and Target CPC became available for new campaigns, and for switching existing ones, on Monday 9 November 2026.
- Max Bid and Max CPC keep running as-is until 1 January 2027. After that date, any campaign still on them is moved automatically to Target CPA or Target CPC.
- Switching to a target-cost model only works well if your conversion tracking is solid — weak signal or an unrealistic target can quietly throttle delivery.
What's changing
On 5 November 2026, OpenAI emailed ChatGPT Ads advertisers about a bidding-model change: two existing options are being retired in favor of cost-target alternatives.
| Retiring | Replaced by | Applies to |
|---|---|---|
| Max Bid | Target CPA (cost per action) | Conversion campaigns |
| Max CPC | Target CPC | Click campaigns |
| Maximize results (autobid) | Intelligent bidding | Rename only, no change |
How Target CPA/CPC actually differ from what you're used to
Target CPA: instead of capping what you're willing to pay per auction, you set an average cost you want per conversion — a purchase, a lead, whatever event you're tracking — and the system adjusts bids and delivery to land near that average across your campaign. New conversion campaigns get this in place of Max Bid by default going forward.
Target CPC: this is the subtler shift. Max CPC capped what you'd pay for any individual click. Target CPC removes that per-auction ceiling — the system can bid above or below your target click by click, aiming to land near your target on average while maximizing total clicks within your budget. If you were relying on Max CPC as a hard ceiling for cost control, Target CPC behaves differently enough that it's worth testing before you lean on it the same way.
The two dates that matter
- 9 November 2026 (already happened): Target CPA and Target CPC became available in Ads Manager, for new campaigns and for switching existing ones over manually.
- 1 January 2027: Max Bid and Max CPC stop being an option. Any campaign you haven't switched yourself gets moved automatically to the equivalent target-cost model.
That gives you roughly seven weeks to switch on your own schedule, test, and adjust targets before OpenAI does it for you.
Before you switch, check these
- Conversion tracking has to be solid first. Confirm your Pixel or Conversions API is actually sending the event you plan to target — purchase, lead, whatever — to the linked data source. Check OpenAI's Event Quality Score (EQS) warnings for signal gaps before you set a target around that event.
- Base your target on real recent numbers, not a wish. Pull your actual CPA or CPC from the last few weeks of delivery. A target set well below what you're currently achieving, or set against thin conversion volume, tends to restrict delivery and leave budget unspent rather than magically lowering your cost.
- Don't switch everything on day one. Move your highest-volume, best-tracked campaign first, watch it for a week or two, then roll the change out to the rest — same logic as testing any new bidding model on Google or Meta.
