Open Markets Institute Urges Court to Ban Google's Default Search Payments

The Open Markets Institute has filed an amicus brief with the U.S. Court of Appeals for the D.C. Circuit, calling for a total ban on Google's payments to maintain its status as the default search engine. The move seeks to prevent the tech giant from using its financial scale to stifle competition in the evolving search and AI markets.

In the filing, Open Markets supports the Department of Justice and state attorneys general in defending a landmark district court ruling. That ruling found that Google illegally maintained a monopoly through exclusionary agreements. The institute argues that any proposed remedies are insufficient if Google is permitted to continue paying companies like Apple billions of dollars to remain the pre-installed search engine on devices and browsers.

The Battle Over Defaults

This legal challenge follows a pivotal court decision that identified Google's exclusionary contracts as the primary mechanism for maintaining its market dominance. As the case moves through the appeals process, the DOJ is seeking specific remedies to restore a competitive landscape. Open Markets contends that the core of the problem is the financial leverage Google wields to block rivals from accessing users.

"An illegal monopoly isn't fixed if the monopolist can simply keep writing the same checks that built it," said Tara Pincock, Policy Counsel at the Open Markets Institute.

Implications for the AI Era

The stakes extend beyond traditional search queries. Because search serves as the foundation for how information is discovered, the ruling will likely dictate the structure of the next generation of the web. Google is currently integrating generative AI into its search products, a move that Open Markets warns could translate current dominance into a permanent gatekeeper position for AI.

According to the brief, the failure to prohibit these payments would allow Google to extend its power into the AI era, potentially replacing a search monopoly with an AI-driven one. Pincock emphasized that the primary concern is whether antitrust remedies will be strong enough to restore fair markets before this transition is complete.

What to Watch

The court's decision on these payments will determine if Google's financial resources can continue to serve as a barrier to entry for competitors. The industry is now waiting to see if the D.C. Circuit will uphold the district court's findings and implement a ban on default payments, or if Google will be allowed to maintain its current distribution strategy as it pivots toward an AI-centric discovery model.
