OpenAI Expands ChatGPT Advertising with Product Carousels, Brazil Launch, and New Conversion Tools

OpenAI is rapidly upgrading its ChatGPT advertising suite ahead of the Q4 shopping season, introducing a multi-product carousel format that automatically pulls items from retailer feeds. The company is also expanding its ad footprint to Brazil and Mexico, bringing its pilot to nine countries. To attract performance-focused budgets, OpenAI has launched conversion-optimized cost-per-click bidding, integrated with partners like Triple Whale, and set an August 17, 2026 deadline for advertisers to opt out of a new automatic advanced matching pixel default.

Product carousel ad format
