OpenAI has made Shopify its first ecommerce partner for ChatGPT Ads, according to OpenAI's own announcement and coverage from Search Engine Land and PPC Land. US merchants can create, manage and track campaigns from a ChatGPT Ads app, with products already wired in through Shopify Catalog; availability in other markets where ChatGPT Ads run is set for September 23. OpenAI is also testing Sponsored Agents, which let a shopper open a conversation with a business-sponsored agent after clicking an ad, and is adding AI creative tools to Ads Manager. OpenAI says ChatGPT advertising went from nothing in February to a $1 billion annual run rate by the end of August. The open question is how users react to ads that talk back.
