EU Fines Google $3.5B for Abusing Its Ad Tech Monopoly

The European Commission has levied a substantial fine against Google’s advertising technology division, amounting to €2.95 billion (approximately $3.5 billion) for distorting fair competition in the digital advertising market through internal favoritism across its own tools, according to the European Commission.

The investigation found that Google, beyond its dominance in search advertising, controlled market demand via its ad-buying tools (Google Ads and DV360), its exchange platform (AdX), and its publishing server (DFP), allegedly exploiting its informational edge to edge out rivals at the last second. It also found that Google Ads systematically bypassed other exchanges, directing bids towards AdX and entrenching its dominance even when superior alternatives existed.

Regulators ordered Google to propose concrete remedies within 60 days and warned that failure to comply could trigger corrective measures, with the possibility of forcing divestitures or a total breakup of parts of its ad tech business. The ruling follows earlier antitrust actions and reflects Brussels’ tougher regulatory stance on tech giants, a stance echoed by Google’s response promising to appeal.
