Judge Denies DOJ Request to Break Up Google Ad Business

WASHINGTON (AP) — A federal judge on Wednesday denied the Department of Justice's request to force Alphabet Inc. to sell its AdX advertising exchange, delivering a major setback to the government's antitrust campaign while upholding the finding that Google illegally monopolized key digital advertising markets.

U.S. District Judge Amit Mehta issued the ruling in Washington, rejecting the structural remedy sought by prosecutors but affirming his earlier conclusion that Google engaged in unlawful conduct within the publisher ad-server and ad-exchange sectors. The decision leaves Google's core advertising infrastructure intact despite the court's determination of a monopoly.

The DOJ had argued that divesting AdX was the only effective way to restore competition in an industry where Google controls approximately 90% of the market for serving ads on websites. Prosecutors contended that without a forced sale, Google would continue to leverage its dominance to exclude rivals and inflate costs for publishers.

In his ruling, Judge Mehta agreed with the government's assessment of Google's anti-competitive behavior but concluded that ordering a breakup was not warranted under current circumstances. The judge indicated that less drastic measures could address the harms identified in the case. This marks a significant divergence from the DOJ's strategy, which has long pushed for structural changes to dismantle what it describes as an entrenched monopoly.

Google, through its parent company Alphabet, welcomed the decision, stating that the ruling validates its position that the market remains competitive and that forced divestiture would harm publishers and consumers. The company has consistently argued that its advertising tools provide essential services to content creators and that breaking up its business would disrupt the digital ecosystem.

The outcome of the case raises immediate questions about what specific remedies will now be imposed. With the option of a forced sale removed, the court must determine whether behavioral changes or other regulatory constraints are sufficient to ensure fair competition. Legal experts suggest the focus may shift to ongoing monitoring and compliance requirements rather than structural separation.

The Department of Justice has not yet announced its next steps but faces pressure to propose alternative solutions that satisfy the court's monopoly finding without dismantling Google's operations. The case has drawn intense scrutiny from lawmakers, tech industry leaders, and advertisers who are watching closely to see how the ruling reshapes the future of online advertising.

As the legal proceedings move forward, the unresolved issue remains whether non-structural remedies can effectively curb Google's market power or if further litigation will be required to achieve the competition goals originally sought by the government. The decision underscores the complexity of regulating dominant technology firms in a rapidly evolving digital economy.
