Alphabet's Google is making its final arguments in a U.S. court today, aiming to prevent the forced breakup of its lucrative advertising technology business as the Department of Justice's antitrust case nears its conclusion. The DOJ and a coalition of states have asked the judge to order Google to sell its ad exchange, AdX, to restore market competition. The closing arguments cap an 11-day trial focused on Google's alleged monopolies in the ad tech space. The government argued that nothing short of a divestiture would stop Google from stifling competition, while Google maintained that a breakup would be technically complex and disruptive for its customers. This follows a previous ruling where the judge found Google holds two illegal ad tech monopolies. The end of these hearings marks a critical point in Google's years-long battle with the DOJ over its dominance in online advertising. The final decision will now be considered, although the legal fight is expected to continue through lengthy appeals processes, regardless of the initial outcome.
