A Federal Judge Just Handed Down Google’s Punishment After Ruling it Ran an Illegal Ad Monopoly

A federal judge already ruled that Google broke the law to build its ad monopoly.

This week that same judge decided exactly what Google has to pay for it.

What she ordered is not what anyone in Washington expected.

Google Built a Machine That Taxes Every Ad Dollar On the Internet

Google controls the software publishers use to sell ad space online.

It also controls the software advertisers use to buy that space.

And it owns the exchange sitting in the middle connecting the two.

That three-sided control let Google skim somewhere between 20 and 30 cents out of every advertising dollar flowing through the open web.

U.S. District Judge Leonie Brinkema ruled last year that Google built and defended that position illegally.

The Justice Department, then led by Attorney General Pam Bondi, called it "a landmark victory in the ongoing fight to stop Google from monopolizing the digital public square."

It was the second time in two years a federal judge branded Google an illegal monopolist, after Judge Amit Mehta ruled Google's search business violated the same law.

The Justice Department originally filed this case in 2023, and it took three more years to reach an actual penalty.

Two separate federal courts. Two separate rulings. The same company running the table.

The Judge Let Google Keep the Machine but Changed How It Runs

On September 2, Brinkema handed down her remedies ruling, and Google did not have to sell a thing.

The Justice Department wanted Google forced to divest AdX, its ad exchange, and DFP, the ad server publishers depend on to manage their inventory.

Brinkema said no to the breakup.

Instead she ordered Google to follow a new list of operating rules.

Google now has to show rival ad servers the real-time bids running through AdX instead of hiding them.

Google has to scrap its Unified Pricing Rules, the system that let Google set the floor in auctions it also profits from as a bidder.

Publishers get to set different minimum prices for different bidders inside Google Ad Manager instead of accepting Google's one-size rule for everyone.

And Google loses its "first look" and "last look" privileges – the auction advantage that let it see rival bids before deciding whether to beat them.

Longtime ad tech executive Jay Friedman asked the question every publisher is already asking: "What is a web publisher to do if it wants to use a different ad server but still get Google's buy-side demand?"

Matt Schruers runs the Computer and Communications Industry Association, the D.C. trade group that counts Google as a member.

He was out front the same day praising Brinkema's call, saying the court "rightly rejected the proposed break-up of Google's ad-tech business."

Microsoft Proved What Happens When the Breakup Never Actually Happens

Washington ran this exact play before.

In 2000, a federal judge ordered Microsoft split into two companies for running an illegal monopoly on desktop software.

An appeals court threw out that breakup a year later.

Microsoft walked away with a conduct decree nobody outside a law school remembers today, and it went on to build the biggest software company on earth.

Twenty-five years later, Google just got the same deal from a different judge in a different case.

Two federal courts, same result: a new stack of operating rules for Google's own lawyers to manage instead of a breakup.

Every conservative website running Google ads is still handing over roughly a third of every dollar to the same company a federal judge ruled broke the law – twice.

That's the number nobody in Washington wants to put on a headline.

Google has already appealed the underlying monopoly finding in its search case, and nothing stops the same legal team from doing it again here.

Every year these rules sit tied up on appeal is another year Google keeps running the exchange exactly the way it built it.
