Google fights DOJ push to break up ad tech business as antitrust trial opens

Alphabet’s Google is back in court, facing a U.S. Department of Justice (DOJ) bid to force it to divest parts of its online advertising empire. The antitrust trial, which opened Monday in Alexandria, Virginia, could reshape the digital ad market if the government succeeds.

The DOJ and a coalition of states want Google to sell its ad exchange AdX, which charges publishers a 20% fee to auction ads in real time, and to make the auction’s decision-making mechanism open source. Prosecutors argue that only structural remedies like divestiture can address Google’s illegal monopolization, after U.S. District Judge Leonie Brinkema ruled earlier this year that Google unlawfully tied AdX to its publisher ad server.

“Leaving Google with the motive and the means to recreate that tie is simply too great a risk,” DOJ attorney Julia Tarver Wood said in opening statements.

Google’s lawyer Karen Dunn pushed back, calling the proposals “radical and reckless,” claiming they would harm competition by giving regulators “broad and unparalleled power” over a major tech platform. Instead, Google has offered policy changes that would make it easier for publishers to work with rivals — but the DOJ insists such tweaks are insufficient.

The trial follows a recent DOJ loss in a separate search monopoly case, where a Washington, D.C. judge refused to impose most of the government’s remedies. But prosecutors argue this case is different, since ad tech is the monopoly itself rather than just a distribution method.

Industry stakeholders are closely watching the outcome. Grant Whitmore of Advance Local, which runs local news outlets in eight states, testified that Google’s control of advertiser tools, publisher tools, and the AdX exchange “offers a lot of opportunities for Google to continue to put their thumb on the scale.” He said Google should also be forced to sell its publisher ad server.

Google has previously floated selling AdX to settle an EU investigation, according to Reuters, and internal documents from those talks may surface during this trial.

The case is part of a broader bipartisan effort to curb Big Tech power, with ongoing actions against Meta, Amazon, and Apple. The stakes are high: a forced breakup of Google’s ad tech stack would mark one of the most significant antitrust interventions in the digital economy’s history.

Google Fined $3.45 Billion by EU for Antitrust Breaches in Adtech; Trump Threatens Retaliation

Google (Alphabet) has been fined €2.95 billion ($3.45 billion) by the European Union for abusing its dominance in the online advertising technology market, marking the fourth major EU penalty against the company in a decade.

The European Commission found that since 2014, Google unfairly favored its own adtech services, particularly its AdX exchange, to the detriment of rivals and online publishers. The watchdog ordered Google to end these self-preferencing practices and address conflicts of interest, warning that stronger remedies, including potential divestitures, remain on the table if compliance efforts fall short. Google has 60 days to propose changes and another 30 days to implement them.

U.S. President Donald Trump blasted the fine as “unfair” and “discriminatory,” threatening to launch a Section 301 trade investigation that could nullify EU penalties and impose retaliatory tariffs. “We cannot let this happen to brilliant American ingenuity,” Trump said, vowing to confront the EU directly.

Google said it would appeal, arguing the decision is “wrong” and would harm European businesses that rely on its services to generate ad revenue. “There’s nothing anticompetitive in providing services for ad buyers and sellers, and there are more alternatives than ever,” said Lee-Anne Mulholland, Google’s VP of regulatory affairs.

The fine comes amid mounting U.S.-EU trade tensions, with Brussels under pressure to balance antitrust enforcement with the risk of Trump’s tariff retaliation on European exports, including cars. While the Commission stopped short of ordering a breakup, critics—including the European Publishers Council—warned that fines alone would not curb Google’s dominance in the €120 billion adtech market.

The ruling adds to Google’s history of penalties in Europe: €4.3 billion in 2018, €2.42 billion in 2017, and €1.49 billion in 2019. Meanwhile, Google faces a U.S. trial in September to determine remedies in a Justice Department case that found it illegally monopolized online advertising.

Google’s advertising business remains the backbone of its revenue, generating $264.6 billion in 2024 (75.6% of total sales) across services including YouTube, Gmail, Maps, and Google Play.

French competition authority launches probe into Meta’s online advertising dominance

The French competition authority announced on Wednesday that it has formally notified Meta Platforms (META.O) of allegations that the company abused its dominant position in the online advertising market. The ongoing investigation, expected to last several months, does not imply immediate liability.

The probe was triggered by a complaint filed in October 2022 by Adloox, an advertising platform now owned by U.S.-based Scope3. In addition, French media giants such as TF1, France TV, and BFM TV are pursuing legal action against Meta over alleged unlawful business practices in the advertising sector.

Meta also faces a high-profile trial in Spain this October, where over 80 media companies have lodged a €551 million ($645 million) complaint accusing the firm of unfair competition in advertising.

Earlier this year, online rights groups filed complaints across Europe targeting Meta’s advertising practices. On the same day as the French announcement, EU antitrust regulators fined Meta and Apple for violations of European Union laws.
