Breaking Up Is Hard to Do: Antitrust Remedies After Google

Google escaped the wrecking ball, but the court’s opinion shows even surgical antitrust remedies can cut deep.

Earlier this week, Judge Mehta (D.D.C.) issued the most consequential antitrust remedy decision in decades. At stake was how to address Google’s unlawful maintenance of its search monopoly. The government pressed for sweeping relief, including the divestiture of Chrome and, potentially, Android. Google, in turn, argued that eliminating exclusivity agreements was remedy enough.

The court landed somewhere in between. Judge Mehta declined to break up the company or force product redesigns, but he did not let Google off with a mere slap on the wrist. Instead, the order requires Google to share key categories of user and search data, authorizes data syndication, bars exclusive contracts that lock up default status, and imposes ongoing monitoring to ensure compliance. With the rise in generative AI chatbots, which represent “a nascent competitive threat,” Judge Mehta’s remedies are designed not only to address the Search market, but also to “ensur[e] that Google’s dominance in search does not carry over into the GenAI space.”

From Liability to Remedy

The liability phase established that Google secured default status on popular devices, leveraged the resulting scale advantage to improve quality, and then parlayed exclusive access to user-interaction data to entrench its dominance. Rivals, deprived of this crucial feedback loop, could not compete.

At the remedy stage, Judge Mehta sought to balance the government’s and Google’s proposals, curing the harm from Google’s anticompetitive conduct with a healthy dose of humility.

The Judge rejected the government’s proposal for “choice screens” directing users to rival search engines as “compelled product design.” He also rejected a ban on payments to Apple and Samsung for default status as overbroad and potentially harmful to competition. However, Judge Mehta acknowledged that defaults are powerful and adopted a wait-and-see approach to see if removing exclusivity and compelling data-sharing alone could foster real competition. Finally, while enforcers urged the divestiture of Chrome (and possibly Android), the court found that the record establishing liability did not justify such a drastic step.

Still, Judge Mehta emphasized that Google could not retain the “fruit” of its unlawful conduct. The opinion mandates that Google provide proprietary search index and user data to its rivals at prices equal to its marginal costs. The court was careful to specify that Google provide data at cost to prevent Google from raising rivals’ costs by charging high prices for data without positioning the court as a price regulator.

By mandating tailored but significant data-sharing and syndication, the court aimed to open space for rivals to compete in both traditional search and in GenAI, without preventing Google from competing in the future.

Restoring Competition Without Divestitures

Judge Mehta’s opinion credited arguments from both the government and Google. He declined to impose a strict requirement that the government prove precisely how each form of requested relief would restore Google to the position it would have been in “but for” its anticompetitive conduct. Instead, he applied a flexible standard, wielding the court’s equitable powers to craft a remedy with a “significant connection” to the conduct at issue.

He also stressed that Google’s market position was not solely the result of misconduct. Strong engineering, product quality, and Microsoft’s slow entry into the search market all contributed to its dominance. Those lawful advantages made “radical structural relief” like divestiture disproportionate.

Finally, the court underscored the institutional limits of judicial remedies. “Courts are neither economic nor industry experts,” Judge Mehta wrote, cautioning that antitrust relief must be approached with humility. Looking ahead, he noted that the surge of investment in AI may finally provide the kind of technological disruption that can loosen Google’s grip.

Implications for Big Tech

The opinion offers a roadmap for other courts considering high-stakes monopolization cases. First, remedies must track the evidence; courts will only impose breakups when narrower measures are shown to be inadequate. Second, data and technology sharing is firmly on the table, even when privacy and intellectual property concerns are raised. And third, remedies must account for technological change. Courts will limit incumbents from leveraging dominance in one market to strangle competition in a nascent one, but they appear to be willing to give firms more leeway when emerging technologies—like generative AI—pose credible competitive threats.

The Takeaway

Google avoided the most dramatic remedy, but the data-sharing requirements still represent a profound change to the status quo. The company faces concrete restrictions that will shape the future of search and create openings for rivals, especially in GenAI. More broadly, the case illustrates how antitrust law is adapting to digital markets—favoring targeted interventions over structural breakups, but not shying away from ordering substantial remedies, like data-sharing.

As generative AI reshapes how people find information, these remedies may prove just as consequential as a breakup in determining whether new challengers can compete on fair terms.
