Google's Chrome browser faces potential divestment as DOJ pushes for antitrust action.

• On Thursday, Alphabet's shares dropped 6% after reports emerged that the Department of Justice wants Google to sell its Chrome browser to end its search dominance.

On Thursday, Google's shares dropped by 6% after the Department of Justice announced its call for Google to divest its Chrome browser to address its search monopoly.

The DOJ's Wednesday filing proposes a permanent end to Google's control over this crucial search access point, allowing rival search engines to access the browser that serves as a gateway to the internet for many users.

The latest development in a years-long antitrust case against the search giant found in an August ruling that the company held an illegal monopoly in both search and text advertising, violating Section 2 of the Sherman Act.

Google would be prohibited from forming exclusive agreements with competitors such as Apple and Samsung for a period of 10 years in the event of a potential break-up.
