In a landmark initiative, the U.S. Department of Justice is pushing for Google to split off key segments of its digital advertising business. The DOJ contends that the tech behemoth is unlawfully monopolizing the ad tech arena, a claim supported by last month’s federal court decision.

The Justice Department aims to expedite the sale of Ad Exchange, a pivotal platform matching advertisers with publishers. Furthermore, they are calling for the gradual divestiture of Google’s DFP ad server, a tool integral for digital ad management. This process, to be overseen by a court official, will grant the DOJ veto power over potential buyers.

Judge Leonie Brinkema has scheduled a trial for September 22 to finalize the corrective strategies, following the court’s recognition of Google’s adverse effects on consumer markets. Notably, the DOJ has unveiled additional measures, urging Google to integrate third-party tools into its system to maintain bidding fairness.

Google’s parent company, Alphabet, which drew nearly $350 billion in 2024, primarily from ads, is expected to fiercely contest these directives. Their leadership argues that the suggested divestitures, particularly in the ad management sector, exceed the judge’s ruling scope. They also claim that such enforced sales may not align with legal allowances.

Despite these pushbacks, speculation about how innovative strategies might reshape market dynamics is rampant. Meanwhile, Google opposes the measures, advocating instead for sharing advertising data with rivals to enhance competitive practices.

The tech giant also faces scrutiny in another antitrust case related to its search monopoly, leading the DOJ to propose the divestment of Google’s Chrome browser. This separate case, judged by Amit Mehta, is predicted to reach a decision by August, possibly heralding a historic change for Google.
