Alphabet's stock experienced a 6% decline after the Department of Justice called for Google to divest its Chrome browser as part of ongoing antitrust measures.

The DOJ's filing aims to dismantle what it describes as Google's search monopoly, asserting that such a move would permanently address Google's control of this critical search access point and promote competition by allowing rival search engines better access to users.

This development is part of a protracted bipartisan antitrust case, which recently concluded that Google maintained an illegal monopoly in both search and text advertising, violating Section 2 of the Sherman Act.

The proposed remedies could also include restrictions on Google's ability to enter into exclusionary agreements with major competitors like Apple and Samsung, with these measures potentially lasting for a decade.
