Prebid’s Proposed Auction Overhaul Would Do What The Court Wouldn’t: Separate AdX From GAM
Prebid's proposed auction overhaul aims to separate Google's AdX ad exchange from its ad server, GAM, even though a federal court did not mandate a breakup. This move could give publishers more ad server flexibility and reduce their dependence on GAM, while also helping Prebid meet the court's integration requirements for Google. The new auction model would allow ad servers to bid into Prebid directly, potentially increasing competition and improving auction efficiency.

Key points from AdExchanger’s report
- Prebid is proposing a new auction model that would let ad servers bid into Prebid rather than Prebid bidding into ad servers.
- The proposed framework is currently in the public comment period and aims to be formalized by the end of Q1.

- The change would also enable Prebid to meet the court's integration requirements for Google, while potentially reducing publishers' dependence on GAM.
