ChatGPT Ads Retires Max Bid on Jan 1: Prep Before Nov 9

OpenAI is changing how you bid in ChatGPT Ads. Starting Monday, November 9, new campaigns default to Target CPA or Target CPC, and the old Max Bid and Max CPC options retire on January 1, 2027. Existing campaigns keep running for now, which makes it easy to ignore until it is not optional.

What Changes and When

• November 9: New conversion campaigns in Ads Manager get Target CPA instead of Max Bid. New click campaigns get Target CPC instead of Max CPC.
• Existing campaigns: Max Bid and Max CPC campaigns keep running as they are, and you can switch them to the new options.
• January 1, 2027: Max Bid and Max CPC retire. Remaining conversion campaigns move to Target CPA, and remaining click campaigns move to Target CPC.
• Renaming: "Maximize results" (autobid) is now called intelligent bidding, and it still adjusts bids and delivery automatically.

OpenAI emailed advertisers about the change on November 5, according to Search Engine Roundtable's report.

Why This Matters More Than a Rename

A Max Bid is a ceiling you set. Target CPA asks the system to find conversions near a cost you name, so the quality of the conversion signal now drives delivery. OpenAI's own guidance says overly restrictive targets or weak conversion signals can reduce delivery and leave budget unspent. For a platform that is still new to most advertisers, a tracking gap you could ignore before can quietly stall a campaign.

What to Check Before Switching

• Conversion signal: Confirm your Pixel or Conversions API is sending the event you plan to optimize for to the linked data source. OpenAI points to Event Quality Score warnings as the place to find signal gaps.
• Your real numbers: Set targets from recent actual CPA or CPC, not from a goal you hope to hit. A target well below what you have been paying can starve delivery.
• Volume: If a campaign gets few conversions, a CPA target has little to learn from. Consider a click campaign with Target CPC until volume builds.
• Move one campaign first: Switch a single campaign, watch delivery and spend for a few days, then move the rest well ahead of January 1.
• Creative settings: Separately, OpenAI turned on creative enhancements by default for self-serve campaigns on October 30. Review that setting while you are in Ads Manager.

Should You Be Running ChatGPT Ads Yet?

That depends on whether you can measure the result. The platform is moving toward automated bidding, which rewards advertisers with clean conversion tracking and punishes the rest. If your tracking is not solid on Google and Meta, fix that first. If it is, a small, capped test is a reasonable way to learn the channel before competition grows.

Frequently Asked Questions

Do I have to change my existing campaigns on November 9?

No. Existing Max Bid and Max CPC campaigns keep running as they are until January 1, 2027. After that they move to Target CPA or Target CPC automatically.

What is the difference between Target CPA and Target CPC?

Target CPA is for conversion campaigns and aims for an average cost per conversion. Target CPC is for click campaigns and aims for an average cost per click.

What happens if my target is too low?

OpenAI says overly restrictive targets can reduce delivery and leave budget unspent. Start from your recent actual cost and adjust gradually.
