ChatGPT Tests Multi-Advertiser Ads: More Ad Space

OpenAI is testing a new way to show multiple advertisers within a single sponsored unit in ChatGPT. This means relevant ads are grouped together, rather than showing one ad per placement. This expands the available ad space for buyers without increasing the number of ads a user sees. These multi-advertiser units are an early test and are limited to a small subset of ads. The ads are priced through a second-price auction, where the highest bidder wins and pays slightly more than the next highest bid. This deepens the auction process. For users, a single labeled sponsored unit will appear below a response, visually separated from the answer. Ads only show up when the chat topic matches an available advertiser. Paid versions of ChatGPT remain ad-free. OpenAI is also adding new tools to its Ads Manager beta, allowing advertisers more control over campaigns and budgets. Targeting for these ads will soon expand to new markets beyond the U.S., Canada, Australia, and New Zealand. This move shows OpenAI is adopting familiar ad platform mechanics to grow its advertising options.
