U.S. District Judge Amit Mehta issued a landmark ruling declaring that Google has operated an illegal monopoly in the general search services and general search text advertising markets. The court determined that Google’s strategy of paying billions of dollars to smartphone manufacturers, such as Apple and Samsung, to ensure its search engine remained the default option on their devices prevented competitors from gaining the scale necessary to challenge Google’s dominance.

In his opinion, Judge Mehta noted that Google’s market share in general search exceeded 80% for years, reaching as high as 90% on mobile devices. The ruling highlights that these exclusive distribution agreements created a 'moat' that shielded Google from meaningful competition. While Google argued that its search engine is simply the best product on the market and that users choose it voluntarily, the court concluded that the company’s exclusionary conduct was a primary driver of its sustained market power.

This decision marks a significant victory for the Department of Justice, which initiated the lawsuit in 2020. The case now moves to a second phase to determine the appropriate remedies, which could range from court-ordered changes to Google’s business practices to more drastic measures, such as forcing the company to divest parts of its business. Google has indicated it plans to appeal the decision, arguing that the ruling ignores the competitive nature of the tech industry and the benefits its services provide to consumers. Legal analysts suggest that the appeals process could take several years, leaving the long-term impact on Google’s business model and the broader tech sector uncertain.
