Judge rules Google illegally monopolized digital ad markets, setting stage for one of the largest tech industry shake-ups in years.
In a decision that could reshape the digital advertising landscape, a U.S. federal judge has ruled that Google illegally maintained monopolies across key segments of the ad tech ecosystem.
The ruling, handed down by Judge Leonie Brinkema of the Eastern District of Virginia, found that Google’s dominance over both the tools publishers use to sell ads and the exchanges where those ads are bought and sold crossed the line into anticompetitive behavior.
In plain terms: Google held too much power in too many places.
“This is a landmark victory in the ongoing fight to stop Google from monopolizing the digital public square,” said Attorney General Pamela Bondi, who brought the lawsuit alongside a coalition of state attorneys general. “This Department of Justice will continue taking bold legal action to protect the American people from encroachments on free speech and free markets by tech companies.”
A Silver Lining For Google
The judge didn’t buy all of the DOJ’s claims. Notably, she dismissed arguments that Google monopolized tools used by advertisers — a partial win for the tech giant. But on the more critical publisher side, the court found Google engaged in illegal conduct, including tying together products and using its control over data and auctions to undercut competitors.
A forced breakup is now a real possibility. The DOJ is pushing for Google to divest parts of its ad tech business, including Google Ad Manager and its ad exchange. That would be one of the most dramatic regulatory moves ever made against a U.S. tech company.
Naturally, Google disagrees with the ruling. The company says its tools are good for publishers and advertisers alike. “We won half of this case, and we will appeal the other half,” Lee-Anne Mulholland, Google’s vice president of regulatory affairs, said.
“The Court found that our advertiser tools and our acquisitions, such as DoubleClick, don’t harm competition. We disagree with the Court’s decision regarding our publisher tools. Publishers have many options and they choose Google because our ad tech tools are simple, affordable and effective.”
This isn’t the first time Google has found itself in hot water over monopoly claims — a separate ruling last month found it violated antitrust laws in the online search space as well. With additional suits looming against Meta, Apple, and Amazon, the heat is rising across Silicon Valley.
As for what comes next? All eyes are now on the remedy phase. Regulators have asked for structural relief — industry-speak for breaking things up.
And if that happens, the digital ad world could soon look very different.
