The U.S. Justice Department on Tuesday filed its second antitrust lawsuit against Google in just over two years. It’s the latest sign that the U.S. government is not backing down from cases against tech firms even in light of a mixed record in court on antitrust suits.
This lawsuit, which is focused on Google’s online advertising business and seeks to make Google divest parts of the business, is the first against the company filed under the Biden administration. The Department’s earlier lawsuit, filed in October 2020 under the Trump administration, accused Google of using its alleged monopoly power to cut off competition for internet search through exclusionary agreements. That case is expected to go to trial in September.
Google’s advertising business generated $54.5 billion in the quarter ended Sept. 30 from Search, YouTube, Google Network ads and other advertising.
Google also faces three other antitrust lawsuits from large groups of state attorneys general, including one focused on its advertising business led by Texas Attorney General Ken Paxton.
The states of California, Colorado, Connecticut, New Jersey, New York, Rhode Island, Tennessee and Virginia joined DOJ in the latest lawsuit.
Google’s advertising business has drawn critics because the platform operates on multiple sides of the market — buying, selling and an ad exchange — giving it unique insight into the process and potential leverage. The company has long denied that it dominates the online advertising market, pointing to the market share of competitors including Meta’s Facebook.
In its lawsuit, the Justice Department and the states argue that Google sought to control all sides of the market, realizing “it could become ‘the be-all, and end-all location for all ad serving.'”
“Google would no longer have to compete on the merits; it could simply set the rules of the game to exclude rivals,” they allege.
They also claim Google acquired other companies, including its 2008 acquisition of publisher ad server DoubleClick and and a “nascent ad exchange” that would become Google’s AdX, to grow its power in the market and “set the stage for Google’s later exclusionary conduct across the ad tech industry.”
“In effect, Google was robbing from Peter (the advertisers) to pay Paul (the publishers), all the while collecting a hefty transaction fee for its own privileged position in the middle,” the enforcers allege. “Rather than helping to fund website publishing, Google was siphoning off advertising dollars for itself through the imposition of supra-competitive fees on its platforms. A rival publisher ad server could not compete with Google’s inflated ad prices, especially without access to Google’s captive advertiser demand from Google Ads.”
The DOJ Antitrust Division’s progressive chief, Jonathan Kanter, had recently been cleared to work on Google-related matters, The Wall Street Journal reported earlier this month. Bloomberg had previously reported that Kanter was not permitted to work on issues involving the company while the Department evaluated Google’s request to review his grounds for recusal. Before his time in government, Kanter represented some of Google’s rivals and critics, including Yelp and News Corp.
A Google spokesperson said in a statement last year that Kanter’s prior work and statements “raise serious concerns about his ability to be impartial.”
Google is far from the only tech giant that has seen scrutiny from the federal government. At the Federal Trade Commission, Meta is also the subject of two antitrust suits, as is Microsoft’s proposed acquisition of Activision.
Google and other tech companies have also faced increasing scrutiny from abroad, particularly in Europe, where Google has also fought multiple competition cases and new regulations threaten major changes to tech business models.
Google did not immediately provide comment on the suit.

How Broadcom’s big OpenAI deal fits into the data center boom and what it means for the AI trade
Oracle CEO, Clay Magouyrk, sits down with CNBC’s David Faber on Oct. 13, 2025.
CNBC
Oracle CEO Clay Magouyrk, one of the two people tapped last month to lead the software company, is confident that OpenAI will be able to cover the costs of the massive amount of cloud infrastructure services it consumes.
In an interview with CNBC’s David Faber at Oracle’s AI World conference on Monday, Magouyrk said “of course” OpenAI can pay $60 billion for a year’s worth of cloud resources. In July, OpenAI agreed to a five-year deal with Oracle that’s worth over $300 billion.
“Just look at the rate at which they’ve grown to, you know, almost a billion users. That’s just unheard of,” said Magouyrk, who sat alongside fellow Oracle CEO Mike Sicilia for the interview in Las Vegas.
OpenAI said last week that its flagship ChatGPT chatbot, which was publicly launched less than three years ago, now has 800 million weekly active users. In 2024, OpenAI recorded a $5 billion net loss.
Sicilia said Oracle has started integrating OpenAI artificial intelligence models into a patient portal for viewing electronic health records. Oracle acquired EHR vendor Cerner for about $28 billion in 2022.
“I’ve seen the results, and I really do think that they’re going to have a dramatic impact on industries, on enterprises of all types,” Sicilia said of OpenAI.
OpenAI rents out Nvidia graphics chips to run models through Oracle, as well as CoreWeave, Google and Microsoft. At the same time, the company is designing a custom AI processor that Broadcom will build. Earlier on Monday, Broadcom and OpenAI said they will jointly deploy 10 gigawatts worth of the new OpenAI chips.
Building out that much infrastructure requires a hefty amount of new energy.
“I think it’s a factor of time, not a factor of if we’ll have enough power,” Sicilia said.
Oracle shares rose almost 6% on Monday. The stock has gained 86% this year, lifting Oracle’s market cap close to $900 billion.
