    OpenAI Ad Deals With Magnite, PubMatic; Google Search Budgets Scrutinized

    OpenAI is expanding its ChatGPT advertising business by partnering with supply-side platforms Magnite and PubMatic to fill unused ad space, following its playbook of opening up inventory to third parties before potentially walling it off, as seen with YouTube, Facebook, and Amazon. The partnerships add to OpenAI's existing ad-tech partners including LiveRamp, Criteo, StackAdapt, and Amazon Ads. Meanwhile, prediction markets like Polymarket and Novig are courting celebrity endorsements despite public skepticism. Additionally, ad buyers are reallocating 10-30% of Google search budgets to other channels due to AI Overviews reducing ad performance and higher CPCs, following Alphabet's earnings report showing a slowdown in search ad growth. Publicis completed its acquisition of LiveRamp, and OpenX appointed Robert Horler as CEO.

    • Magnite and PubMatic have signed deals with OpenAI to fill unused ChatGPT ad space.
    • OpenAI's ad-tech partners include LiveRamp, Criteo, StackAdapt, and Amazon Ads.
    • Polymarket launched a celebrity ad campaign featuring LeBron James, Derek Jeter, and others.
