Google Faces Potential Breakup of $3.6 Trillion Ad Business
A federal judge is considering forcing Google to dismantle parts of its advertising technology empire—a move that could mark the first major breakup of a Big Tech company and threaten the foundation of its $3.64 trillion business.
Key Takeaways
- Google faces potential forced sale of its AdX exchange and other ad tech units
- Judge Leonie Brinkema heard closing arguments in the landmark antitrust case
- DOJ demands “root and branch” overhaul of Google’s ad business practices
- Decision expected next year, with Google certain to appeal regardless of outcome
Landmark Antitrust Battle Reaches Critical Stage
Judge Leonie Brinkema of the US District Court for the Eastern District of Virginia presided over three hours of closing arguments on Friday regarding remedies for Google’s illegal ad tech monopoly. The Justice Department is pushing for the forced sale of Google’s AdX exchange and other aggressive measures to restore competition.
The scale of Google’s ad dominance is staggering: the company processes 8.2 million ad space requests every second and collects a 20% fee from publishers, according to The New York Times. This advertising technology funds Google’s dominance across search, video, and artificial intelligence.
DOJ Demands “Root and Branch” Overhaul
The government wants Google to spin off technology that facilitates transactions between ad buyers and sellers, while also requiring data sharing with competitors. DOJ attorney Matthew Huppert argued that only a forced sale could effectively restore competition.
“The remedy needs to eradicate Google’s illegally acquired monopolies root and branch,” Huppert told the court, according to Reuters.
The government contends Google used its market dominance to extract larger transaction fees from publishers and advertisers.
Google Pushes Back Against Breakup Proposal
Google’s lead attorney Karen Dunn countered that a breakup would be “extreme” and technically challenging, potentially causing significant disruption for customers. She advocated for behavioral changes instead, arguing these could be implemented within 12-15 months compared to the years required for a divestiture.
Timing Concerns and Impending Appeal
Judge Brinkema, who ruled in April that Google holds two illegal ad tech monopolies, expressed concerns about the timeline. With Google certain to appeal regardless of the outcome, she questioned whether faster-acting behavioral remedies might be more practical than a lengthy breakup process.
The judge emphasized that “time is of the essence” given the rapidly evolving digital advertising industry. Her final decision is expected next year.
This case represents a crucial test for antitrust enforcement in the tech sector. If ordered, it would be the first forced breakup of a tech giant since the government’s campaign to regulate Big Tech began during President Trump’s first term. Google recently avoided similar breakup demands in a separate search monopoly case.
