Antitrust officials with the US Department of Justice declined to comment on a Bloomberg report that they will ask for a sell-off of Chrome and a shake-up of other aspects of Google's business in court Wednesday.
Justice officials in October said they would demand that Google make profound changes to how it does business -- even considering the possibility of a breakup -- after the tech juggernaut was found to be running an illegal monopoly.
The government said in a court filing that it was considering options that included "structural" changes, which could see them asking for a divestment of its smartphone Android operating system or its Chrome browser.
Calling for the breakup of Google would mark a profound change by the US government's reglators, which have largely left tech giants alone since failing to break up Microsoft two decades ago.
Google dismissed the idea at the time as "radical."
Adam Kovacevich, chief executive of industry trade group Chamber of Progress, released a statement arguing that what justice officials reportedly want is "fantastical" and defies legal standards, instead calling for narrowly tailored remedies.
Determining how to address Google's wrongs is the next stage of a landmark antitrust trial that saw the company in August ruled a monopoly by US District Court Judge Amit Mehta.
Requiring Google to make its search data available to rivals was also on the table.
Regardless of Judge Mehta's eventual decision, Google is expected to appeal the ruling, potentially prolonging the process for years and possibly reaching the US Supreme Court.
The trial, which concluded last year, scrutinized Google's confidential agreements with smartphone manufacturers, including Apple.
These deals involve substantial payments to secure Google's search engine as the default option on browsers, iPhones and other devices.
The judge determined that this arrangement provided Google with unparalleled access to user data, enabling it to develop its search engine into a globally dominant platform.
From this position, Google expanded its tech empire to include the Chrome browser, Maps and the Android smartphone operating system.
According to the judgment, Google controlled 90 percent of the US online search market in 2020, with an even higher share, 95 percent, on mobile devices.
Remedies being sought will include imposing measures curbing Google artificial intelligence from tapping into website data and barring the Android mobile operating system from being bundled with the company's other offerings, according to the report.
