ChatGPT Ads now uses cost targets instead of bid caps. From 9 November 2026, new conversion campaigns in OpenAI’s Ads Manager use ChatGPT Ads Target CPA instead of Max Bid, and new click campaigns use Target CPC instead of Max CPC. Existing campaigns keep running until both old options retire on 1 January 2027. Targets are averages, not ceilings, so set them from your real recent costs.
Key takeaways
- New default for new campaigns (9 November 2026): Target CPA replaces Max Bid for conversion campaigns, and Target CPC replaces Max CPC for click campaigns.
- Averages, not caps: individual clicks or conversions can cost more or less than your target.
- Old caps retire on 1 January 2027: campaigns still on Max Bid or Max CPC then move to Target CPA or Target CPC.
- Renamed: “Maximize results” is now called “intelligent bidding.”
- Signals matter: OpenAI asks conversion advertisers to confirm their Pixel or Conversions API sends the selected event, and warns that tight targets or weak signals can leave budget unspent.
What changed in ChatGPT Ads bidding?
On 5 November 2026, OpenAI emailed advertisers about changes to their bidding options, as Search Engine Roundtable reported, and updated its bidding help page, as Search Engine Journal reported. The change replaces two manual bid caps with two average cost targets.
Before this change, conversion and click campaigns in Ads Manager could use an automatic option (“Maximize results”) or a manual limit: Max Bid for conversion campaigns and Max CPC for click campaigns. From 9 November, new campaigns get target options instead of those limits.
| Campaign goal | Old option (bid cap) | New option (cost target) | How the new option works |
|---|---|---|---|
| Conversions (purchases, leads) | Max Bid | Target CPA | You set the average cost per conversion you want; the system adjusts bids and delivery to work towards it |
| Clicks | Max CPC | Target CPC | The system can bid above or below your target in each auction, aiming for as many clicks as possible within your budget at your average CPC |
| Automatic (no target) | Maximize results | Intelligent bidding | A new name for the automatic option; it still adjusts bids and delivery for you |

What is ChatGPT Ads Target CPA, and how is it different from Max Bid?
Target CPA is the average amount you are willing to pay for a conversion, such as a purchase or a lead. OpenAI’s system then raises or lowers bids auction by auction to get as close as it can to that average across the campaign.
Max Bid worked the other way round: it set a limit, and the system would not go past it. That gave advertisers a hard ceiling, but in our view it also meant the system could skip auctions where a slightly higher bid would have produced a cheap conversion overall.
The key point is that Target CPA is an average. OpenAI says individual results can cost more or less than the target, and the campaign’s actual average can also end up higher or lower, as Search Engine Journal reports. If your business needs a strict maximum per lead, a target will not give you that guarantee.
How does Target CPC work in ChatGPT Ads?
Target CPC applies to click campaigns. OpenAI’s explanation, quoted by Search Engine Journal, is that Max CPC capped individual bids, while Target CPC lets the system bid above or below your target in individual auctions. The aim is as many clicks as possible within your budget at the average cost per click you set.
If you have seen Target CPA in Google Ads or cost targets in Meta Ads, the idea will feel familiar. ChatGPT Ads is not alone in moving away from manual caps: Search Engine Journal notes that Microsoft Advertising said in August it would stop offering Max CPC on new non-portfolio campaigns using strategies such as Target CPA and Target ROAS from 1 October; existing campaigns and portfolio strategies can still use it. For a wider comparison of the two search-style platforms, see our guide to Google Ads vs ChatGPT Ads.
How much do you pay with a target?
OpenAI’s bidding page says “the final winning auction bid sets the price you pay,” and that this applies to all bidding strategies, including existing Max Bid and Max CPC campaigns (quoted by Search Engine Journal). It also separates two settings that are easy to mix up:
- Bidding goal: what the system optimizes for (conversions or clicks, with or without a target).
- Billing event: what you are charged for (clicks or impressions). A Target CPA campaign can optimize for conversions while being billed per click or per impression.
Search Engine Journal also noticed that OpenAI’s “basics” page still mentions setting maximum bids at the ad-group level and suggests starting CPC campaigns at a maximum bid of $3 to $5 per click. The help pages were being updated at different speeds, so treat the bidding page as the current reference.
What are the key dates?
| Date | What happens | Who it affects |
|---|---|---|
| 5 November 2026 | OpenAI emails advertisers and updates its bidding help page; “Maximize results” renamed “intelligent bidding” | All ChatGPT Ads advertisers |
| 9 November 2026 | Target CPA and Target CPC become the options for new campaigns in Ads Manager; existing campaigns can switch | Ads Manager advertisers |
| 18 November 2026 | Values sent through the old Max Bid or Max CPC API fields to create a campaign or change an ad group’s bid type are treated as average targets, not maximums | Advertisers using API partners |
| End of December 2026 | Legacy API fields remain supported until this point | API partners |
| 1 January 2027 | Max Bid and Max CPC retire for existing campaigns; legacy API fields deprecated | Everyone still on the old options |
OpenAI has not said what target value a campaign will receive if it is still on Max Bid or Max CPC on 1 January, as both Search Engine Journal and Soku point out. Switching yourself before then lets you choose the number.
How do you set your first Target CPA or Target CPC?
OpenAI’s advice, as reported by Search Engine Roundtable and Search Engine Journal, comes down to good data and realistic numbers. Here it is step by step, with a few steps of our own and one from Search Engine Journal:
- Check your conversion signal first. OpenAI asks advertisers to confirm that the Pixel or Conversions API is sending the selected event to the data source linked to the campaign, and to use Event Quality Score (EQS) warnings to find gaps. If tracking is new to you, our guide to tracking ChatGPT traffic in GA4 is a good companion.
- Work out your real recent cost. Divide spend by attributed conversions (or clicks). OpenAI’s example: $400 of spend and 10 attributed purchases is a $40 actual CPA.
- Set the first target near that number. In the same example, a $20 target will not suddenly produce $20 purchases. OpenAI warns that restrictive targets or weak conversion signals “can reduce ad delivery and leave budget unspent.”
- Change one campaign at a time. In our view, moving your best-performing campaign first and leaving the rest on their current settings makes it easier to see what the target changed.
- Watch spend, volume and actual average cost. Search Engine Journal recommends monitoring total spend, clicks, conversions and actual average cost as the campaign learns.
- Adjust gradually. Once delivery is stable, move the target in small steps towards the cost your margins need.
The logic is similar to the learning period on other platforms: automated bidding needs enough conversion data to work well. We explain that idea for Meta in Meta Ads learning phase: the 50-conversion rule.
Does this matter for advertisers in Lebanon and the Gulf?
It depends on whether you can run ChatGPT Ads in your market yet. Reuters reported on 21 October 2026 (via The Star) that OpenAI expanded ChatGPT ads to 26 more countries, for 89 in total, with access through technology partners or self-service in Ads Manager. That report names countries in Latin America, Africa, Europe and Asia, and says the launch covers the Middle East, but it does not list any Middle Eastern country by name. Check the current country list in Ads Manager before planning budget.
Ads appear to users on ChatGPT’s Free and Go plans; Plus, Pro and Enterprise remain ad-free, according to the same Reuters report. If you are starting from zero, read how to advertise on ChatGPT for the setup, then come back to bidding.
In our view, the skills transfer even if ChatGPT Ads is not open in your country yet. Target-based bidding, conversion tracking and realistic cost goals are the same disciplines that drive results in Google Ads and Meta Ads today.
What should you do now?
- List every ChatGPT Ads campaign still on Max Bid or Max CPC, and note its actual average CPA or CPC over recent weeks.
- Confirm your Pixel or Conversions API sends the right event, and clear any EQS warnings.
- Move one campaign to Target CPA or Target CPC, starting near its real recent cost.
- If you use an API partner, ask which bid fields their tool sends after 18 November.
- Plan to move the remaining campaigns yourself before 1 January 2027 rather than waiting for the automatic switch.
- Keep creative fresh while bidding settles; see ChatGPT Ads creative enhancements for what OpenAI changed on the creative side.
Frequently asked questions
What is Target CPA in ChatGPT Ads?
Target CPA is a bidding option for conversion campaigns in ChatGPT Ads. You set the average amount you want to pay for a conversion, such as a purchase or a lead, and OpenAI’s system adjusts bids and delivery to work towards it. Since 9 November 2026 it replaces Max Bid for new conversion campaigns in Ads Manager.
What is the difference between Max CPC and Target CPC?
Max CPC caps each individual bid. Target CPC is an average: OpenAI says its system can bid above or below your target in individual auctions while aiming for as many clicks as possible at the average cost per click you set.
Do my existing Max Bid or Max CPC campaigns stop on 9 November?
No. Existing campaigns keep running with their current settings, and you can switch them to a target whenever you are ready. Max Bid and Max CPC retire on 1 January 2027, when the remaining campaigns move to Target CPA or Target CPC.
Is Target CPA a guaranteed price per conversion?
No. OpenAI describes the target as an average, so individual conversions can cost more or less, and your actual average can also land above or below the target. A target that is much lower than your recent results can reduce delivery.
What happened to “Maximize results” bidding?
It has been renamed “intelligent bidding.” The reports describe it as a new name for the same automatic option, which adjusts bids and delivery for you.
How should I set my first Target CPA?
Start from your recent actual cost per conversion, not from the number you wish you were paying. OpenAI’s own example: $400 of spend and 10 attributed purchases is a $40 actual CPA, so a $20 target will not produce $20 purchases. Check that your Pixel or Conversions API is sending the right event first.
What changes for advertisers who buy ChatGPT Ads through an API partner?
From 18 November 2026, values sent through the old Max Bid or Max CPC API fields to create a campaign or change an ad group’s bid type are treated as average targets, not maximums. The legacy fields are supported until the end of December and deprecated on 1 January 2027, so ask your partner which fields their tool sends.
