OpenAI connects Magnite and PubMatic to remnant ad sales in ChatGPT

ChatGPT advertising is joining the conventional automated market, giving major buyers an easier route through existing systems and OpenAI another way to fill ad inventory.
According to The Information, the agreements let advertisers set budgets, place bids and upload creative for ChatGPT through the familiar Magnite and PubMatic platforms, while OpenAI retains control over ad placement and delivery. The arrangements cover inventory not sold directly; current volume through the new partners is small, and participants expect it to grow as integration deepens. OpenAI is expanding its advertising infrastructure after agreements with Criteo, LiveRamp, StackAdapt and Amazon Ads. A company spokesperson told The Information that the new connections make it easier to buy and manage ads through tools advertisers already use.
