A federal judge in Virginia recently issued a ruling on remedies in the longstanding Google ad tech antitrust case. Despite a prior ruling that Google unlawfully monopolized the digital advertising market, the new order refrains from ordering structural changes, allowing Google to retain key components of its advertising technology stack.
- Judge allows Google to keep control of its ad exchange and server
- New rules focus on auction operations, not structural separation
- Legislation proposed to ban dominant platform conflicts and boost competition
What happened
In April 2025, a federal judge in Virginia ruled that Google held an illegal monopoly in the digital advertising technology market by consolidating the key layers of the ad-buying process under its control. The ruling found Google engaged in anti-competitive behavior including self-preferencing and price manipulation. However, the remedies order issued in September 2026 stops short of forcing Google to divest any assets or overhaul its operations. Google will continue to own both its ad server and ad exchange, a combination identified as creating inherent conflicts of interest in prior litigation.
The recent decision instead alters operational rules governing Google's ad auctions in an attempt to limit Google's leverage over publishers and advertisers. While specifics remain under seal, public commentary suggests the changes focus on improving transparency and limiting some forms of preferential treatment. Despite calls from advocates and the US Department of Justice for more robust action—including structural remedies—the ruling preserves Google's dominant position in the ad tech ecosystem.
Why it matters
Google’s continued control over key components of the advertising technology stack preserves its ability to exert outsized influence on how digital ads are bought and sold. This influence impacts advertisers who face higher costs and less transparency, publishers who must raise paywalls or face revenue losses, and consumers who deal with privacy intrusions and limited viewpoint diversity. The ruling's limited scope means the structural issues underpinning these harms remain unaddressed.
This outcome underscores the challenges of relying on litigation alone to check the power of multi-trillion-dollar tech conglomerates in fast-moving markets. It signals to policymakers and advocates that piecemeal operational adjustments may be insufficient. Many experts stress the need for comprehensive legislative measures and independent digital regulation to foster competition, interoperability, and data rights, thereby restoring a more equitable and dynamic ad ecosystem.
What to watch next
Attention now turns to pending legislation in the US Senate such as the American Innovation and Choice Online Act (AICOA) and the Advertising Middlemen Endangering Rigorous Internet Competition Accountability Act (AMERICA Act). These bills aim to directly prohibit dominant platforms from self-preferencing, require data portability, and prevent firms from controlling multiple layers of the ad-buying process. Their progress could reshape the digital advertising landscape more decisively than litigation outcomes alone.
Stakeholders will also monitor the enforcement of the court’s remedies to see whether they effectively limit Google’s anti-competitive practices in practice. Additionally, calls for establishing a dedicated digital regulator to oversee these complex markets continue to grow. The evolving regulatory response will be critical in determining whether Google’s market dominance is meaningfully checked or allowed to persist unchallenged.
