DOJ Warns Google Could Use AI Tools to Extend Search Monopoly As Antitrust Remedies Trial Begins

 |  April 21, 2025

As hearings got underway Monday in the remedies phase of the Justice Department’s successful antitrust lawsuit against Google over its dominance of online search, DOJ lawyer David Dahlquist told the court in opening arguments that strong measures are needed to make sure Google cannot leverage its artificial intelligence products to further extend its search-engine monopoly.

“This court’s remedy should be forward-looking and not ignore what is on the horizon,” Dahlquist said, according to reports from inside the courtroom. “The time to tell Google and all other monopolists who are out there listening, and they are listening, that there are consequences when you break the antitrust laws.”

U.S. District Judge Amit Mehta ruled in August that Google illegally used its market power to crush search-engine competitors and maintain its monopoly. He is now considering proposals from each side as to appropriate remedies to restore competition to the search market.

DOJ, which was joined in bringing the case a bipartisan group of state attorneys general, has proposed forcing Google to divest its Chrome browser and barring it from paying mobile phone makers to make Google the default search-engine on their devices. If that fails to restore competition within five years, the government further urges the court, Google should also be made to sell its Android mobile operating system.

In his own opening statement, Google attorney John Schmidtlein called those proposed remedies “extreme” and “fundamentally flawed,” according to the reports.

“Google won its place in the market fair and square,” Schmidtlein said, according to the Washington Post, adding that the government’s proposals “will reward competitors with advantages they never would have earned in a market where Google competed.”

Google vowed last year to appeal Judge Mehta’s ruling once the remedies phase is finished and proposed far more modest steps, such as providing browser makers with more flexibility in selecting a search engine to incorporate and allowing Android device makers to pre-load more search engines on phones and tablets.

Google share of the search market has fallen in recent years, from nearly 90% in 2020 to closer to 80% today, as AI-powered competitors such as OpenAI’s SearchGPT and Perplexity AI, both of which are expected to testify in the case.

However, Google has also become a major player in so-called retrieval augmented search (RAG), which combines a large language AI model with traditional search technology. Its Google Overviews summaries now appear at the top of its search results pages.

DOJ and the states are concerned that Google’s leading position in AI could allow it to once against crowd out potential competitors in AI-powered search.

“I think ChatGPT is doing just fine without any of the remedies in the case,” Schmidtlein answered.
