The findings determined that Google violated Article 102 of the Treaty on the Functioning of the European Union by favoring its own advertising technology services over competitors between 2014 and 2025. Among the specific anticompetitive practices identified, the Commission found that Google's demand-side platform DV360 systematically reduced bids submitted to rival supply-side platforms to discourage header bidding and divert demand toward AdX.
The Commission's Executive Vice-President Teresa Ribera stated in September that at this stage, it appears that the only way for Google to end its conflict of interest effectively is with a structural remedy, such as selling some part of its ad tech business. This represents an unusually strong indication from Brussels that behavioral modifications would be insufficient to address the competition concerns.
However, the Commission has expressed significant skepticism about behavioral remedies. Competition lawyer Damien Geradin characterized Google's proposed behavioral modifications as entirely useless, predicting Brussels will conclude structural remedies are necessary. The provisional decision warns that as long as the structural conflicts of interest have not been removed, Google's ability and incentive to favor its own operations would remain.
Google filed an annulment action with the EU's General Court on January 12, challenging the Commission's decision. The company maintains the Commission errs in its assessments of market definition and dominance, and that conclusions over its ad tech practices were also in error.
The Department of Justice has sought complete divestiture of Google's AdX exchange and open-sourcing of DFP's final auction logic. During November closing arguments, Judge Brinkema expressed skepticism about structural remedies, questioning whether divestiture could be enforced during appeals and concerns about identifying qualified buyers for AdX.
Industry observers anticipate final remedial decisions in the first half of 2026, though the complexity of technical issues and legal challenges may extend deliberations. The case represents one of the most significant antitrust enforcement actions against a major technology company in recent years, with potential implications for how vertically integrated digital platforms operate across multiple layers of a market.

The European Commission has published its provisional 363-page decision confirming that Google has dominated digital advertising technology markets for over a decade, warning that only structural remedies potentially forcing the tech giant to sell parts of its ad tech business may effectively end the company's conflicts of interest. The ruling, released on January 14, 2026, reaffirms a 2.95 billion euro fine imposed in September 2025 and provides detailed findings of Google's market dominance and anticompetitive practices.
Market Dominance and Abuse Findings
The Commission's investigation revealed that Google held 91 percent market share in publisher ad servers through DoubleClick for Publishers and 60 to 70 percent dominance in ad exchange markets through AdX. Investigators concluded that Google's vertically integrated ad tech stack created enduring structural conflicts of interest that enabled exclusionary conduct and could not be remedied by competition on the merits alone.The findings determined that Google violated Article 102 of the Treaty on the Functioning of the European Union by favoring its own advertising technology services over competitors between 2014 and 2025. Among the specific anticompetitive practices identified, the Commission found that Google's demand-side platform DV360 systematically reduced bids submitted to rival supply-side platforms to discourage header bidding and divert demand toward AdX.
Mechanisms of Market Manipulation
Investigators discovered that Google used First Look and Last Look mechanisms to allow AdX to observe or react to rival bids in ways unavailable to competitors, fundamentally distorting auction outcomes. These practices effectively gave Google's ad exchange an unfair advantage in every transaction, undermining the competitive process that should determine ad placements and prices.The Commission's Executive Vice-President Teresa Ribera stated in September that at this stage, it appears that the only way for Google to end its conflict of interest effectively is with a structural remedy, such as selling some part of its ad tech business. This represents an unusually strong indication from Brussels that behavioral modifications would be insufficient to address the competition concerns.
Google's Response and Regulatory Skepticism
Google submitted its compliance plan on November 13, 2025, rejecting structural remedies and proposing behavioral modifications instead. The company argued its proposal fully addresses the Commission's decision without a disruptive breakup that would harm the thousands of European publishers and advertisers who use Google tools to grow their business.However, the Commission has expressed significant skepticism about behavioral remedies. Competition lawyer Damien Geradin characterized Google's proposed behavioral modifications as entirely useless, predicting Brussels will conclude structural remedies are necessary. The provisional decision warns that as long as the structural conflicts of interest have not been removed, Google's ability and incentive to favor its own operations would remain.

Parallel United States Proceedings
The European developments occur alongside similar proceedings in the United States, where Judge Leonie Brinkema of the US District Court for the Eastern District of Virginia is expected to deliver her remedies ruling in the coming weeks. In April 2025, Brinkema found Google liable for monopolizing the publisher ad server and ad exchange markets.The Department of Justice has sought complete divestiture of Google's AdX exchange and open-sourcing of DFP's final auction logic. During November closing arguments, Judge Brinkema expressed skepticism about structural remedies, questioning whether divestiture could be enforced during appeals and concerns about identifying qualified buyers for AdX.
Industry Impact and Timeline
The decisions could fundamentally reshape digital advertising markets worth hundreds of billions globally. The way ads get placed on websites, how much publishers earn from their content, and how much advertisers pay for audience reach could all change dramatically if Google is forced to divest key components of its ad tech infrastructure.Industry observers anticipate final remedial decisions in the first half of 2026, though the complexity of technical issues and legal challenges may extend deliberations.
