A Judge Split the Difference in One of Tech's Biggest Antitrust Cases

Keypoints:

• Judge Leonie Brinkema declined to force Google to sell its AdX ad exchange
• The ruling followed her earlier finding that Google illegally monopolized ad tech markets
• Google must stop tying its ad server to AdX and follow new interoperability rules
• A court-appointed monitor will oversee compliance for six years
• It's the third consecutive Big Tech breakup bid federal courts have rejected

A federal judge handed Google a partial win and a real constraint at the same time. Judge Leonie Brinkema of the Eastern District of Virginia rejected the Department of Justice's push to force Google to sell AdX, its digital ad exchange, even after finding last year that the company illegally monopolized the publisher ad tech market.

The decision doesn't undo that earlier finding. Google can no longer tie access to its ad server, Google Ad Manager, to use of AdX, a practice the court found let Google disadvantage rival ad exchanges and publishers who tried to use them. 

Instead of a breakup, Brinkema opted for behavioral remedies: new interoperability requirements, data-sharing rules, and anti-discrimination provisions, backed by a court-appointed monitor overseeing Google's compliance for six years.

CCIA President Matt Schruers welcomed the outcome directly, saying the court "rightly rejected the proposed break-up of Google's ad-tech business, which would have gone far beyond the judge's original findings in the case." 

That framing matters for what comes next in tech antitrust generally. This marks the third time in recent years a federal court has found a major tech company violated antitrust law, then stopped short of ordering the company broken apart, a pattern that's starting to look less like caution in one case and more like a real judicial standard for how far these remedies will go.
