A U.S. federal court has proposed a remedy that would require Google to change its advertising auction rules and expand interoperability with competitors, rather than forcing it to spin off its ad technology business. A monitor and a technical committee to oversee compliance are also set to operate for six years.
This decision is the result of the remedial phase that followed the court's April 2025 ruling that Google had maintained an illegal monopoly in certain online advertising technology markets. Although the U.S. Department of Justice's demand to sell AdX was not accepted,, Changes are now underway to the structure that has restricted competition by bundling Google's ad servers and ad exchanges for use together.
However, based on the decision that has been made public, the U.S. government and Google still need to submit their final proposals. Google has also stated that it will appeal part of the liability ruling. We will have to wait and see how the actual timeline and scope of the institutional changes unfold as subsequent legal procedures proceed.
| Why Corrective Action Was Chosen Over a Business Spin-off
The U.S. Department of Justice demanded the sale of AdX, an ad exchange where website operators sell ads. It determined that without a structural breakup, Google could revert to monopolistic behavior.
Federal District Court Judge Leonie Brinkema They believed that competition could be restored by expanding access to real-time auctions instead of sales and by restricting bundled usage. The court ruled that this measure was sufficient to open the affected ad tech market to competition and prevent a recurrence of anti-competitive conduct.
From Google's perspective, We’ve avoided the worst-case scenario of having to spin off our core advertising technology business. However, since we’ll need to change how products are integrated, the bidding rules, and data access conditions, business operations won’t continue exactly as they are now.
| The integration between AdX and the ad server has changed
The practice of pressuring websites that use Google's DFP ad server for publishers to also use Google's AdX has been restricted. AdX must also submit real-time bids to competitors' ad servers for publishers.
According to an announcement by the Department of Justice, Google must develop and support integration capabilities that connect AdX and DFP with Prebid, an open-source real-time bidding standard. This will allow website operators to access Google’s ad demand while also This could open up more options for choosing other ad servers and tools.
The court also restricted AdWords—an advertising tool—from giving preferential treatment to Google-owned tools in the bidding process. This measure is intended to reduce the likelihood that competing tools are excluded from the bidding process, even if the products are not completely separated.
| Data Migration and Expanded Access for Competitors
Google is We need to ensure that publishers can access and export their data from DFP and AdX. The goal is to reduce the difficulty of switching to another ad tech provider caused by data being locked in.
There are also plans to expand the disclosure of information on how ad auctions work and to provide technical support to competitors. In the ad tech market, where countless automated bids are placed in the blink of an eye, data access and the rules governing connections between products have a significant impact on actual competition.
However, Just because technical integration is now possible doesn't mean competitors will immediately secure the same level of ad demand and user base. The specifics of the implementation and the quality of Google's support could determine the extent of market changes.
| Six Years of Oversight and Technical Committee Operations
The court ordered Google to be subject to oversight by an antitrust compliance monitor and a technical committee to ensure it complies with the final order. The term is six years—shorter than the 15 years requested by the U.S. government.
The monitoring system involves complex ad auctions and product-linking rules that My role will be to verify that the system actually works, rather than just ensuring that the documentation has been updated. We can also monitor whether new methods are emerging that delay competitors' access or set unfavorable technical conditions.
The specific authorities and reporting procedures are expected to become clearer in the final directive. Whether the supervisory body has access to sufficient technical data could be key to its enforcement capabilities.
| Changes to the Website and Advertising Markets
Website operators will likely have more freedom to choose ad servers for publishers while still leveraging Google's ad demand. If data migration becomes easier, the cost of testing other ad tech services could also decrease.
While this presents an opportunity for advertisers and ad tech competitors to reduce disparities in the bidding process, it remains unclear how these changes will affect ad rates or commissions. Given the complexity of the ad auction structure, it may take some time for the effects of these measures to become apparent.
Google has stated that it disagrees with the ruling and plans to appeal. Therefore, market participants We need to confirm whether certain measures will be suspended or modified during the implementation of the final order and the appeals process.
| Things to Check Before Issuing the Final Command
What has been confirmed so far is that, while the court rejected the proposed breakup, it did determine a set of remedies, including interconnection, data sharing, restrictions on self-preferencing, and six years of oversight. The government and Google must submit a final order reflecting these decisions to the court.
This decision does not overturn the finding that Google's ad technology business constitutes an illegal monopoly, nor does it order the company to immediately split up. You could say this is a phase for testing how much the market can be opened through behavioral adjustments.
From now on We need to look at the specific wording of the final order, the outcome of the appeal, when integration with competing ad servers and Prebid will actually be available, and whether publishers see an increase in conversions.
