The US Department of Justice (DOJ) has called for a partial breakup of Google, asking a federal judge to force the sale of its Chrome web browser. This follows a landmark ruling earlier this year that found Google guilty of violating antitrust laws by maintaining an illegal monopoly in its search business.
Unprecedented Action Against Big Tech
The DOJ’s move, supported by several states, marks one of the most significant antitrust actions against a tech giant in decades. The proposal also targets Google’s growing dominance in artificial intelligence (AI), with penalties that could transform how Americans search for information and use online services.
Chrome Spin-Off and Restrictions on Default Agreements
Antitrust enforcers propose spinning off Chrome, used by billions globally, to prevent future monopolistic practices. They also demand a ban on Google’s exclusive contracts with companies like Apple and Samsung, which made Google the default search engine on their devices. These agreements, ruled illegal in August by District Judge Amit Mehta, were pivotal in cementing Google’s dominance.

Levelling the Search Market
The DOJ has recommended requiring Google to syndicate its US search results to rival search engines for a decade. This measure aims to create a fairer competitive landscape, allowing alternatives like Bing and DuckDuckGo to gain traction.
AI Concerns Highlighted by Microsoft
The case underscores fears that Google could use its dominance in search to train its AI tools unfairly. Microsoft CEO Satya Nadella warned last year of a potential “nightmare” scenario if Google is allowed to leverage billions of daily search queries as AI training data. Microsoft, which competes with Google through its Bing search engine and an exclusive partnership with OpenAI, has struggled to challenge Google’s market dominance.
Longstanding Antitrust Violations
The DOJ’s case, filed in 2020, alleged that Google used interlocking strategies to stifle competition and limit consumer choice. Judge Mehta ruled that Google’s tactics violated the Sherman Act, a cornerstone of US antitrust law, describing the company as a monopolist acting to maintain its dominance.
Broader Remedies Proposed
In addition to divesting Chrome, the DOJ has proposed separating Google Search from its Android operating system and Google Play app store. While these changes may not involve outright breakups, they aim to dismantle Google’s tightly integrated ecosystem and reduce its market power.
Echoes of the Microsoft Antitrust Case
The case draws parallels to the DOJ’s 1990s action against Microsoft, where the company was accused of bundling Internet Explorer with its Windows operating system to suppress competition. That case ultimately led to more competition, paving the way for browsers like Chrome and Firefox.
Additional Antitrust Challenges for Google
Google faces separate antitrust battles, including a case over alleged monopolization of the digital advertising market. This trial, filed in 2023, is ongoing, with closing arguments expected soon.
Final Decision Expected in 2025
The court is set to deliberate on the DOJ’s proposals in a multi-month process, with a final decision anticipated in 2025. If approved, these measures could mark a turning point for antitrust enforcement in the tech industry, reshaping the digital landscape and curbing Google’s influence.
