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.
