What the Google ad-tech remedies trial got right (and what it missed)

I. The order. On April 30, Judge Leonie Brinkema (E.D. Va.) issued a 213-page remedies order in United States v. Google LLC, Case No. 1:23-cv-00108. The order, in its operative paragraphs, requires Google to divest its ad-exchange (AdX) within twenty-four months and to allow third-party ad servers to interoperate with Google Ad Manager via a documented API set within nine. The remedies are structural rather than behavioral, which the DOJ had argued for and which the trial record had supported.

II. The defense. Google's position throughout the remedies phase was that behavioral remedies — interoperability mandates, monitoring trustees, periodic audits — would be sufficient to address the conduct findings without the disruption that divestiture entails. The opinion explicitly engages this argument at section IV.B and rejects it on a factual record that Brinkema describes as "warranting structural relief." The opinion cites Microsoft III at five points and Standard Oil at one, in the lineage that any competition lawyer reading the order will have predicted.

III. The footnote that matters

The provision worth reading carefully is footnote 47 (page 154 of the slip opinion). It addresses the AI-driven bid-logic functionality that Google has been incrementally adding to AdX since late 2024. Brinkema notes, in language that has been deliberately spare, that "no remedy adopted herein is intended to disturb innovation in algorithmic bidding except insofar as such innovation is achieved by leveraging the structural advantages this Court has identified." That sentence is doing a lot of work.

What it commits the court to, in the appellate phase, is a posture in which the AI-driven bid logic is not, by itself, an instrument of monopolization. What it does not do is foreclose a second phase of remedies if the divestiture, once complete, leaves the AI-driven bid logic on the wrong side of the structural line. The footnote is not a concession. It is a reservation.

IV. What the appellate panel will care about

Google has indicated it will appeal. The Fourth Circuit panel will draw on the active senior-circuit-judge pool, and the swing vote in this category of case has historically been Judge Wynn. The opinion is structured in a way that anticipates appellate review — the conduct-finding sections cross-reference the remedies sections with unusual care — and on the record of the trial, the structural relief is well-supported. Predictions in this category are expensive, and I will not make one. The next docket entry to read: Google's notice of appeal, expected within thirty days of the order, and the stay motion that will accompany it.
