Google’s Ad Tech Monopoly: A Judge’s Ruling Awaits

25 Nov, 2025

The future of Google's advertising technology monopoly now rests with Judge Leonie M. Brinkema. Recently, she presided over a three-hour closing argument session involving the Justice Department and Google, focusing on how to address the company's dominance in ad tech. The judge's decision is expected next year, and it could significantly impact how Google operates in the advertising space.

The Justice Department is advocating for a major overhaul, proposing that Google spin off its ad exchange—a system that facilitates transactions between advertisers and publishers. They argue this is essential to foster competition and reduce Google's control. In contrast, Google has put forth a more limited approach, suggesting minor changes rather than a complete breakup.

Judge Brinkema has previously ruled that Google violated antitrust laws in maintaining its dominance in certain areas of advertising technology. Her upcoming decision could be unprecedented, as it might represent the first significant breakup of a tech giant in the modern internet age.

This case reflects a broader governmental effort to rein in major tech companies. While the Justice Department has had some victories, they face challenges, as seen in recent cases involving competitors like Meta. The advertising technology lawsuit, filed in 2023, positions Google as a central figure in discussions surrounding monopolistic practices in the tech industry.

Google’s ad system, which processes millions of requests every second, has come under scrutiny for allegedly taking an excessive portion of transaction profits. Brinkema's prior ruling confirmed that Google monopolizes key areas of the ad system, particularly the tools used by publishers to sell ads.

The discussions have raised important questions about the timing of any potential breakup. Critics warn that if the process takes too long, it may not effectively change the competitive landscape. The Justice Department argues that immediate action is vital, while Google's legal team contends that a quicker resolution through less drastic measures could be achieved.

As the legal battle continues, the implications of Judge Brinkema's decision extend beyond just Google. It may set a precedent for how governments regulate the power of tech giants and reshape the future of digital advertising, impacting businesses and consumers alike.
