ChatGPT Ads Bidding: What Changes on November 9, 2026

OpenAI is changing ChatGPT Ads bidding. From Monday, November 9, 2026, Target CPA replaces Max Bid for new conversion campaigns and Target CPC replaces Max CPC for new click campaigns. Both targets are averages, so the system can bid above or below them in any single auction. Existing campaigns keep their settings until advertisers switch, and on January 1, 2027, OpenAI retires Max Bid and Max CPC and moves any remaining campaigns to targets. On the organic side, a screenshot shared on November 6 shows OpenAI testing a tool that lets verified businesses claim their listing in ChatGPT, track how often they're mentioned and clicked each day, update products and let a business agent answer questions. OpenAI hasn't announced it. The channel is large: more than 1.2 billion people use ChatGPT each week, ads run in 89 countries and Adthena counted 204,489 ad placements from June to September. But a working paper found US paid ChatGPT visits earned $0.89 each against $2.45 for Google search ads, so advertisers should set targets from their own data and measure results carefully.
