Judge rejects Google ad tech breakup in antitrust ruling

The court will adopt a series of modifications designed to curb anticompetitive practices, including restrictions on self-preferencing auction tactics and mandates for third-party access to real-time data. These specifics remain under review as the parties work to redact confidential information before the final opinion is released. Google maintains the right to appeal the underlying monopoly finding, a path the company is already pursuing in a separate federal case concerning its dominance in online search.

Judge Brinkema’s decision confirms that Google’s practice of tying its publisher ad server, Doubleclick for Publishers, to its AdX exchange created an environment where competition could not thrive. However, the ruling narrowed the scope of the DOJ’s victory by finding that the government failed to prove an illegal monopoly existed within the advertiser-side tools market. Lee-Anne Mulholland, Google’s vice president of regulatory affairs, welcomed the rejection of the breakup proposal, characterizing the tools as essential for small business growth. The outcome marks a significant chapter in a broader federal effort to reshape the tech landscape, following recent antitrust litigation involving Meta, Amazon, and Apple.
