The Commission accused Google of distorting competition by unfairly favoring its own display advertising technology services. This practice allegedly hurt rival adtech providers, advertisers, and online publishers who compete in the same space.
EU competition chief Teresa Ribera delivered harsh words for the tech giant. “Today’s decision shows that Google abused its dominant position in adtech harming publishers, advertisers, and consumers,” she said in a statement.
The ruling goes beyond just financial punishment. Google must “bring these self-preferencing practices to an end” and implement measures to address conflicts of interest throughout the adtech supply chain.

The company has 60 days to respond with compliance plans. If Google fails to provide satisfactory remedies, regulators warned they will impose stronger measures.
Ribera hinted at potential structural changes. She noted that “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 Adtech business.”
Google Fights Back
Google’s global head of regulatory affairs Lee-Anne Mulholland rejected the Commission’s findings. She called the EU decision “wrong” and announced the company will appeal.
“It imposes an unjustified fine and requires changes that will hurt thousands of European businesses,” Mulholland said. She argued the changes would make it harder for European businesses to generate revenue.
The company defended its advertising practices. Google maintains there is “nothing anticompetitive in providing services for ad buyers and sellers” and points to increased competition in the market.
Google expects to record the fine in its third quarter results. The company filed this disclosure with the Securities and Exchange Commission.
This represents Google’s second major EU antitrust fine. The Commission previously imposed a €4.12 billion penalty in 2018 over Google’s Android mobile system practices.
Trade Tensions Emerge
The fine triggered immediate political backlash from Washington. President Donald Trump posted on Truth Social, calling the penalty “very unfair” to American companies.
Trump warned his administration may launch a trade investigation. This could result in new tariffs on European goods as retaliation for the Google ruling.
The timing creates complications for ongoing trade negotiations. Brussels and Washington have been working on a trade deal agreed in late July.
EU trade chief Maroš Šefčovič had reportedly delayed announcing the Google fine earlier this week. Sources familiar with the process said concerns over trade talks influenced the timing.
The case dates back to 2021 when the EU first opened its probe into Google’s adtech practices. Regulators spent years investigating whether the tech giant gave unfair advantages to its own services.
Google also faces regulatory pressure in the United States. A federal court ruled last year that Google holds an illegal monopoly in search.

U.S. regulators initially sought to break up Chrome browser or Android system operations. However, a federal judge rejected that approach earlier this week, ordering data sharing and contract restrictions instead.
The latest EU fine demonstrates continued regulatory pressure on Google’s advertising business from both sides of the Atlantic. Google stock maintains a Strong Buy consensus rating with analysts setting an average price target of $235.42.
