Google Keeps AdX, but the Ad Tech Ruling Rewrites How Its Auctions Work Worldwide

Judge Brinkema's unsealed opinion swaps a breakup for six years of global conduct rules, a court-appointed monitor and forced interoperability with Prebid.

Judge Leonie Brinkema's full 106-page remedies opinion in the US ad tech case against Google was unsealed on Wednesday, two weeks after a short order in which she refused the Justice Department's request to force a sale of the AdX exchange. The detail confirms that Google keeps its ad tech stack intact. In exchange it accepts six years of behavioural rules, a court-appointed monitor with real investigative powers, an internal compliance officer, and a technical committee to settle disputes. The rules apply wherever Google's ad tech operates, not just in the US. The parties owe the court a joint proposed final judgment by 2 October, and the remedies take effect 60 days after it is entered.
