OpenAI announced a new advertising stack on September 16, 2026. Sponsored Agents let users opt into a clearly labeled conversation with a business-sponsored agent after clicking a ChatGPT ad; the test is limited to select U.S. advertisers. Advertisers can also create, update and analyze campaigns through natural-language prompts in ChatGPT using the Ads Manager plugin. Ads Manager adds AI-assisted copy and imagery plus optional contextual text customization and translation. HubSpot and Shopify integrations are available, with international Shopify availability planned for markets supporting ChatGPT Ads from September 23. Source: OpenAI, September 16, 2026.
