United States of America v. Google LLC
N/A (Slip Opinion) (2025)
Rule of Law:
In a Section 2 Sherman Act remedies phase, relief must be tailored to fit the specific violation and deny the defendant the fruits of its unlawful conduct; however, structural remedies like divestiture require a heightened showing of a significant causal connection between the exclusionary conduct and the maintenance of monopoly power.
Facts:
- For over a decade, Google maintained a monopoly in general search services (over 90% market share) and general search text advertising.
- Google secured its dominance by paying billions of dollars annually to browser developers (like Apple and Mozilla), original equipment manufacturers (OEMs like Samsung), and wireless carriers (like AT&T) to be the exclusive, out-of-the-box default search engine.
- These exclusive agreements prevented rivals from obtaining the 'scale'—specifically the volume of user queries and click data—necessary to improve search quality and compete effectively.
- The massive volume of user data Google collected allowed it to improve its search algorithms and monetization, creating a 'network effects' flywheel that further entrenched its dominance.
- Generative AI (GenAI) products, such as ChatGPT and Perplexity, recently emerged as potential competitors to traditional search engines, though they rely on search index data for 'grounding' to ensure accuracy.
- Google integrated its own GenAI features (AI Overviews) into Search, further utilizing its data advantage to answer 'long-tail' (rare) queries that competitors struggle to answer due to a lack of data scale.
- Third-party partners became dependent on Google's revenue share payments, creating an ecosystem resistant to changing search providers.
Procedural Posture:
- The U.S. Department of Justice and various States sued Google in the U.S. District Court for the District of Columbia alleging violations of Section 2 of the Sherman Act.
- The Court bifurcated the proceedings into a liability phase and a remedies phase.
- Following a trial on the merits, the District Court issued a liability opinion ruling that Google violated Section 2 by maintaining a monopoly in general search services and search text advertising through exclusive distribution agreements.
- The parties submitted proposed final judgments and the Court held an evidentiary hearing regarding the appropriate remedies.

Issue:
What equitable remedies are appropriate to redress Google's maintenance of a monopoly in general search services and text advertising, specifically regarding whether the court should order the divestiture of Chrome and Android, ban payments for default distribution, or compel data sharing with rivals?
Opinions:
Majority - Judge Mehta
No to structural divestitures and a complete payment ban, but yes to ending exclusive contracts and compelling data sharing. The Court held that while Google violated the Sherman Act, the remedy must be proportional to the proven harm. Regarding structural remedies, the Court declined to order the divestiture of Chrome or Android. Citing United States v. Microsoft Corp., the Court applied a heightened causation standard, finding Plaintiffs failed to prove a 'significant causal connection' between Google's exclusionary contracts and its maintenance of monopoly power sufficient to warrant breaking up the company, noting that Google's success is also attributable to legitimate innovation and quality. Regarding the payment ban, the Court rejected a complete prohibition on Google paying partners for distribution. The Court reasoned that a total ban would harm the ecosystem (crippling revenues for partners like Mozilla and OEMs) and potentially reduce competition by preventing Google from bidding against rivals. However, the Court enjoined Google from enforcing exclusivity clauses, meaning Google can pay for placement but cannot contractually prevent partners from dealing with rivals. To 'deny the fruits' of the violation (scale), the Court ordered Google to share specific data with 'Qualified Competitors.' Google must share its Search Index data (at marginal cost) and specific user-interaction data (Glue and RankEmbed datasets) to allow rivals to improve their search quality. The Court also ordered Google to syndicate search results to competitors for five years to serve as a bridge while they build their own indexes. Finally, the Court extended these remedies to the GenAI market to prevent Google from leveraging its search monopoly into the emerging AI sector.
Analysis:
This opinion represents a significant development in modern antitrust jurisprudence regarding digital platforms. First, it reinforces the Microsoft III standard that structural remedies (breakups) require a much higher evidentiary burden regarding causation than liability findings do; the court is unwilling to break up a company based on exclusionary contracts alone without proof that the monopoly would not exist 'but for' those contracts. Second, the decision pivots toward 'data as a remedy.' By forcing Google to share the 'fruits' of its monopoly (user interaction data and search indices) rather than destroying the company, the court attempts to engineer competition by lowering barriers to entry (scale) for rivals. Third, the opinion explicitly brings Generative AI into the scope of the remedy, recognizing that the definition of 'search' is evolving and ensuring that Google cannot use its legacy monopoly to dominate the new AI frontier.
