Google Keeps Its Ad Stack, but the Remedies Test Begins

Last week Judge Leonie Brinkema rejected the U.S. Department of Justice's proposed structural remedies in its ad tech antitrust case against Google, sparing the company from divesting its AdX exchange or its publisher ad server Google Ad Manager (formerly DoubleClick for Publishers), and from open-sourcing DFP's final auction logic. Instead the court accepted most of the behavioral remedies, subject to modification, so Google keeps the businesses but must operate them under conduct restrictions that have not yet been finalised. Brinkema gave Google and the government 30 days to submit a proposed final judgment, and where the two sides disagree each must file its own preferred version for the court to settle. Digiday's read is that the significance of the ruling turns less on the absence of a breakup than on how consequential those behavioral restrictions prove in practice, with the publisher-side focus shifting to whether remedies improve interoperability and access to auction data.

The crux

The ownership fight is over and Google won, but the real contest is now whether behavioral remedies actually open up auction data and interoperability for publishers, or merely codify the status quo with Google still in control of both the ad server and the exchange.

Sell-side read

No divestiture removes the disruptive restructuring publishers had feared, but it also removes the one change that might have forced a renegotiation of the supply chain. The upside now hinges entirely on the conduct terms: publishers should be pushing hard, before the 30-day window closes, for the auction-data access and interoperability language that actually moves yield.

Watch

The 30-day final-judgment window, closing in early October: whether Google and the DOJ agree on the conduct provisions or force Brinkema to resolve contested terms.
