Google Avoids Forced Divestiture in Ad Tech Antitrust Loss, Judge Orders Behavioral Remedies Instead
Developing story first seen 1 hour ago
A US federal judge has spared Google a forced breakup of its advertising technology business, ruling that behavioural restrictions rather than divestiture will address the company's illegal monopolisation of ad tech markets. Judge Leonie Brinkema said she would adopt most of the remedies already proposed jointly by the Department of Justice and Google, with some modifications, rather than impose the more drastic structural sell-off the DOJ had sought. The decision follows Brinkema's earlier ruling that Google unlawfully tied together its DoubleClick for Publishers ad server and AdX ad exchange, entrenching its dominance and making it nearly impossible for customers to switch providers.
The specific remedies remain confidential for now, pending further negotiation between the parties and redaction of sensitive material, but could include curbs on Google's self-preferencing in ad auctions and requirements to give rival ad tech tools access to the same real-time data Google uses. Brinkema also found the DOJ had not proven a separate monopoly claim over advertiser-side tools. Google, which called the ruling a win for small businesses, may still appeal the underlying monopoly finding, echoing a similar case where Judge Amit Mehta likewise rejected a breakup of Google's search business in favour of data-sharing and conduct remedies. The ruling closes the district court phase of a wider wave of US tech antitrust action, which has also seen the FTC lose a monopolisation case against Meta, with cases against Amazon and Apple still to come.

Google has been fighting a series of US antitrust cases over how it runs its online advertising business, which sits between advertisers who want to buy ad space and website publishers who want to sell it. The case centres on whether Google unfairly favoured its own tools, such as its DoubleClick ad server and AdX ad exchange, making it hard for publishers to use rival services. The Department of Justice, representing the US government, brought the case and had pushed for Google to be forced to sell off parts of its ad tech business.
The judge overseeing the case, Leonie Brinkema, had already ruled earlier that Google broke the law by tying its ad products together in a way that entrenched its dominance. The question left to resolve was what should be done about it: whether Google should be broken up, or whether it should instead be made to change how it behaves while keeping the business intact.
This case is part of a broader wave of US government efforts to challenge the market power of major technology companies, including similar action against Google's search business and other firms such as Meta, Amazon and Apple. How courts choose to punish proven monopolies, through break-ups versus rules on conduct, is being closely watched as it may shape how future cases against big tech are decided.
Full account
A US federal judge has stopped short of ordering Google to sell off its advertising exchange, dealing the Department of Justice a partial setback in the closely watched ad tech antitrust case it won against the company last year. Judge Leonie Brinkema, sitting in the Eastern District of Virginia, ruled that behavioural changes to Google's conduct, rather than a break-up of its business, would be sufficient to restore competition to the publisher ad server and ad exchange markets the court had earlier found Google had illegally monopolised. The DOJ and a coalition of state attorneys general had pushed for divestiture of the exchange, formerly branded AdX, arguing it was the only remedy strong enough to loosen Google's grip on the plumbing of the online display advertising industry.
Brinkema's underlying liability ruling had found that Google unlawfully tied its publisher ad server, DoubleClick for Publishers, to its AdX exchange in a way that made it extremely difficult for publishers to switch away, entrenching Google's dominance over how online display ad space is bought and sold. However, the judge did not accept the government's separate argument that Google had also illegally monopolised the market for advertiser-facing tools, a narrower finding than prosecutors had sought. Having decided against a forced sale, Brinkema is instead adopting most of the behavioural remedies proposed during the trial, with some amendments of her own; these are expected to address practices such as Google favouring its own exchange in auctions and could require it to give rival ad tech systems access to bidding data on more equal terms. The precise wording has been kept under seal for a fortnight to allow both sides to flag material that should be redacted before the opinion is made public.
Google welcomed the outcome, with the company's vice president of regulatory affairs, Lee-Anne Mulholland, saying it was pleased the court had rejected calls to dismantle products used by small businesses to reach customers. The Justice Department struck a more upbeat tone than the result might suggest, with its Antitrust Division describing itself as pleased that substantial relief had been ordered and saying it was weighing further steps; a senior DOJ official framed the timing of the decision as reflecting a trade-off between securing remedies quickly and the years such litigation can otherwise consume. Google is expected to have the option of appealing the original finding of illegal monopolisation once the redacted opinion is finalised, mirroring its response to a similar antitrust defeat in its search business.
The ruling closes out the trial phase of the third major US government monopoly case against a large technology company in recent years, following an earlier defeat for Google in the DOJ's search antitrust suit, where a judge likewise declined to order a break-up, opting instead to require data-sharing with rivals and an end to certain exclusive distribution arrangements, and a separate case brought by Epic Games over Android app distribution. Coverage has noted that Google has now avoided divestiture in all three proceedings despite losing on the substance of liability in each, leaving it materially better off than the harshest remedies floated during the cases while still facing constraints on how it runs its ad, search and mobile businesses. Scrutiny of Google's market power has persisted across changes in Washington, drawing criticism from figures on both sides of the political aisle even as enforcement priorities have shifted between administrations.
Where outlets differ
One account frames the story mainly around Google's escape from the harsher penalty, stressing that the ad exchange is a small slice of Google's revenue and drawing a fuller comparison with the earlier Chrome/search case and the Epic Games Android case, plus noting the 14-day seal before remedy details emerge.
The other account gives more granular detail on what the behavioural remedies might actually contain (e.g. limits on self-preferencing in auctions, third-party access to real-time bidding data), includes direct quotes from Google's Lee-Anne Mulholland and the DOJ's Stanley Woodward Jr., flags a potential conflict of interest (a deposed executive works for its own parent company), and adds political context about bipartisan criticism of Google from figures such as JD Vance and Lina Khan.
There is a difference in emphasis on the liability finding: one source focuses on the top-line 'Google broke the law but escapes break-up' narrative, while the other goes into more depth on the specific distinction between the publisher-tool monopolisation finding (upheld) and the advertiser-tool monopolisation claim (rejected).
