The DOJ’s antitrust case against Google is ambitious but risky

The Department of Justice’s latest challenge to Google’s tech empire is an ambitious swing at the company with the potential to rearrange the digital advertising market. But alongside the possibility of great reward comes significant risk in seeking to push the boundaries of antitrust law.
“DOJ is going big or going home here,” said Daniel Francis, who teaches antitrust at NYU School of Law and previously worked as deputy director of the Federal Trade Commission’s Bureau of Competition, where he worked on the agency’s monopoly case against Facebook.

The DOJ’s antitrust chief Jonathan Kanter has indicated he’s comfortable with taking risks, often saying in public remarks that it’s important to bring cases that seek to challenge current conventions in antitrust law. He said he prefers more permanent remedies like breakups compared to promises to change behavior. That sentiment comes through in the DOJ’s request in its latest lawsuit for the court to force Google to spin off parts of its ad business.
Antitrust experts say the Justice Department paints a compelling story about the ways Google allegedly used acquisitions and exclusionary strategies to fend off rivals and maintain monopoly power in the digital advertising space. It’s one that, if the government gets its way, would break apart a business that’s generated more than $50 billion in revenue for Google in the last quarter, potentially opening up an entire market in which Google is currently one of the most important players.
But, they warn, the government will face significant challenges in proving its case in a court system that progressive antitrust enforcers and many lawmakers believe has taken on a myopic view of the scope of antitrust law, especially when it comes to digital markets.
“If they prove the violations they allege, they’re going to get a remedy that’s going to shake up the market,” said Doug Melamed, a scholar-in-residence at Stanford Law School who served at the Antitrust Division, including as acting assistant attorney general, from 1996-2001 during the landmark case against Microsoft. “But it’s not obvious they’re going to win this case.”
Challenges and strengths
Experts interviewed for this article said the DOJ will face the challenge of charting relatively underexplored areas of antitrust law in proving to the court that Google’s conduct violated the law and harmed competition without benefitting consumers. Though that’s a tall order, it could come with a huge upside if the agency succeeds, possibly expanding the scope of antitrust law for digital monopoly cases to come.
“All antitrust cases are an uphill battle for plaintiffs, thanks to 40 years of case law,” said Rebecca Haw Allensworth, an antitrust professor at Vanderbilt Law School. “This one’s no exception.”
But, Allensworth added, the government’s challenges may be different than those in many other antitrust cases.
“Usually the difficulty, especially in cases involving platforms, is market definition,” she said. In this case, the government argued the relevant market is publisher ad servers, ad exchanges, and advertiser ad networks — the three sides of the advertising stack Google has its hand in, which the DOJ said it’s leveraged to box out rivals. “And here, I think that that is relatively straightforward for the DOJ.”
“One way to look at the latest complaint is that it is the newest and most complete draft of a critique that antitrust agencies in the U.S. and abroad have been building against Google for over a decade,” William Kovacic, who served on the Federal Trade Commission from 2006 to 2011 and is now a professor at George Washington Law, said in an email.
Google, for its part, has said the latest DOJ lawsuit “tries to rewrite history at the expense of publishers, advertisers and internet users.” It claims the government is trying to “pick winners and losers” and that its products have expanded options for publishers and advertisers.
Compared to the DOJ’s earlier lawsuit, which argued Google maintained its monopoly over search services through exclusionary contracts with phone manufacturers, this one advances more nontraditional theories of harm, according to Francis, the NYU Law professor and former FTC official. That also makes it more likely that Google will move to dismiss the case to at least narrow the claims it may have to fight later on — a move it did not take in the earlier suit, he added.
“This case breaks much more new ground and it articulates theories, or it seems to articulate theories, that are right out on the border of what existing antitrust prohibits,” Francis said. “And we’re going to find out, when all is said and done, where the boundaries of digital monopolization really lie.”
High risk, high reward?

DOJ took a gamble with this case. But if it wins, the rewards could match the risk.
“In terms of the potential impact of the remedy, this could be a bigger case than Microsoft,” said Melamed.
Still, Francis cautioned, a court could order a less disruptive remedy, like paying damages if it finds the government was harmed as an advertising purchaser, or simply requiring Google to stop the allegedly illegal conduct, even if it rules in the DOJ’s favor.
Like all antitrust cases, this one is unlikely to be concluded anytime soon. Still, a key decision by the Justice Department could make it speedier than otherwise expected. The agency filed the case in the Eastern District of Virginia, which has gained a reputation as the “rocket docket” for its relatively efficient pace in moving cases along.
“What that signals to me is that, given the timeframe for antitrust litigation is notoriously slow, DOJ is doing everything that they can in their choice of venue to ensure that this litigation moves forward before technological and commercial changes make it obsolete,” Francis said.
He added that the judge who has been assigned the trial, Clinton appointee Leonie Brinkema, is regarded as smart and fair and has handled antitrust cases before, including one Francis litigated years ago.
“I could imagine that both sides will feel pretty good about having drawn Judge Brinkema as a fair, efficient and sophisticated judge who will move the case along in an expeditious way,” Francis said.
Still, there are hardly any judges who have experience with a case like this one, simply because there haven’t been that many digital monopolization cases decided in court.
“So any judge who would be hearing this case is going to be confronting frontier issues of antitrust theory and principle,” Francis said.
Immediate impact
Outside of the courts, the case could have a more immediate impact in other ways.
“From the point of view of strategy, the case adds a major complication to Google’s defense by increasing the multiplicity and seriousness of public agency antitrust enforcement challenges,” said Kovacic, the former FTC commissioner. “The swarming of enforcement at home and abroad is forcing the company to defend itself in multiple fora in the US and in jurisdictions such as the EU and India.”
Regardless of outcomes, Kovacic said the sheer volume of lawsuits and regulation can create a distraction for top management and will likely lead Google to more carefully consider its actions.
“That can be a serious drag on company performance,” Kovacic wrote.
The suit could also lend credence to lawmakers’ efforts to legislate around digital ad markets. One proposal, the Competition and Transparency in Digital Advertising Act, would prohibit large companies like Google from owning more than one part of the digital advertising system, so it couldn’t own tools on both the buy and sell side as it currently does.
Importantly, the bill is sponsored by Sen. Mike Lee, R-Utah, the ranking member of the Senate Judiciary subcommittee on antitrust. Lee has remained skeptical of some other digital market antitrust reforms, but his leadership on this bill suggests there may be a broader group of Republicans willing to support this kind of measure.
“An antitrust lawsuit is good, but will take a long time and apply to only one company,” Lee tweeted following the DOJ’s announcement, saying he would soon reintroduce the measure. “We need to make sure competition works for everyone, and soon.”
Rep. Ken Buck, R-Colo., who has backed the House version of the bill, called the digital ad legislation “The most important bill we can move forward” in a recent interview with The Washington Post.
“This is clearly the blockbuster case so far from the DOJ antitrust division,” Francis said. “And I think it represents a flagship effort to establish new law on the borders of monopolization doctrine. And at the end of it — win, lose or draw — it’s really going to contribute to our understanding of what the Sherman Act actually prohibits in tech markets.”

It’s been a tough November for Palantir.
Shares of the software analytics provider dropped 16% for their worst month since August 2023 as investors dumped AI stocks due to valuation fears. Meanwhile, famed investor Michael Burry doubled down on the artificial intelligence trade and bet against the company.
Palantir started November off on a high note.
The Denver-based company topped Wall Street’s third-quarter earnings and revenue expectations. Palantir also posted its second-straight $1 billion revenue quarter, but high valuation concerns contributed to a post-print selloff.
In a note to clients, Jefferies analysts called Palantir’s valuation “extreme” and argued investors would find better risk-reward in AI names such as Microsoft and Snowflake. Analysts at RBC Capital Markets raised concerns about the company’s “increasingly concentrated growth profile,” while Deutsche Bank called the valuation “very difficult to wrap our heads around.”
Adding fuel to the post-earnings selloff was the revelation that Burry is betting against Palantir and AI chipmaker Nvidia. Burry, who is widely known for predicting the housing crisis that occurred in 2008 and the portrayal of him in the film “The Big Short,” later accused hyperscalers of artificially boosting earnings.
Palantir CEO Alex Karp vocally hit the front lines, appearing twice in one week on CNBC, where he accused Burry of “market manipulation” and called the investor’s actions “egregious.”
“The idea that chips and ontology is what you want to short is bats— crazy,” Karp told CNBC’s “Squawk Box.”
Despite the vicious selloff, Palantir has notched some deal wins this month. That included a multiyear contract with consulting firm PwC to speed up AI adoption in the U.K. and a deal with aircraft engine maintenance company FTAI.
But those announcements did little to shake off valuation worries that have haunted all AI-tied companies in November.
Across the board, investors have viciously ditched the high-priced group, citing fears of stretched valuations and a bubble.
In November, Nvidia pulled back more than 12%, while Microsoft and Amazon dropped about 5% each. Quantum computing names such as Rigetti Computing and D-Wave Quantum have shed more than a third of their value.
Apple and Alphabet were the only Magnificent 7 stocks to end the month with gains.
Sill, questions linger over Palantir’s valuation, and those worries aren’t a new concern.
Even after its steep price drop, the company’s stock trades at 233 times forward earnings. By comparison, Nvidia and Alphabet traded at about 38 times and 30 times, respectively, at Friday’s close.
Karp, who has long defended the company, didn’t miss an opportunity to clap back at his critics, arguing in a letter to shareholders that the company is making it feasible for everyday investors to attain rates of return once “limited to the most successful venture capitalists in Palo Alto.”
“Please turn on the conventional television and see how unhappy those that didn’t invest in us are,” Karp said during an earnings call. “Enjoy, get some popcorn. They’re crying. We are every day making this company better, and we’re doing it for this nation, for allied countries.”
Palantir declined to comment for this story.
