ChatGPT Ads tests multi-product carousel, expands to Brazil and Mexico
OpenAI is testing a multi-product carousel format for ChatGPT product feed ads and will launch ChatGPT Ads in Brazil and Mexico in the coming week, per Search Engine Roundtable. The same advertiser update adds a conversion-optimized bidding (oCPC) beta for product feed campaigns, dynamic URL macros, and new Triple Whale and Hightouch measurement integrations. OpenAI will also make Automatic Advanced Matching the default for existing Web pixels on August 17, 2026, unless advertisers opt out first.
Why it matters: OpenAI is expanding ChatGPT Ads geographically while deepening its measurement stack, the fourth advertiser-facing update in two weeks.
