Google Loses Appeal in Epic Games App Store Overhaul Ruling

The 9th U.S. Circuit Court of Appeals has rejected Google’s appeal in Epic Games’ 2020 antitrust lawsuit, upholding a lower court order to open the Play Store to competing app marketplaces and sideloading. The ruling removes the stay on these requirements, marking a major shift in Android app distribution. Google’s objections—centered on its defense of Play Store competition with Apple—were not accepted.

Background of the Epic vs. Google Antitrust Battle

Epic Games filed its lawsuit against Google in August 2020, accusing the tech giant of stifling competition through its Play Store policies. After a 2023 jury verdict sided with Epic, the trial judge in October 2024 ordered Google to open its app marketplace to third-party stores and sideloading options. Google promptly appealed, putting the mandate on hold.

On July 31, 2025, a three-judge panel of the 9th U.S. Circuit Court of Appeals ruled that the trial judge had not made legal errors. The court rejected Google's argument that it was unfairly barred from arguing Play Store competition against Apple's App Store. With the stay lifted, Google must begin implementing significant changes to Android app distribution.

Appeals Court Decision

The appeals court found no procedural mistakes in the lower court’s handling of evidence or jury instructions. Google’s push to revisit whether the Play Store competes with Apple’s App Store was dismissed as a collateral issue. This cements the October 2024 order, forcing Google to give Android users more choice for downloading apps.

Implications for Developers and Platform Operators

  • Expanded distribution channels: Third-party app stores can reach Android users directly.
  • Fee renegotiations: Developers may leverage competitive marketplaces to reduce commission costs.
  • Security and compliance: New sideloading options will require rigorous vetting to protect users.

What’s Next for Google

Google now faces a tight deadline to propose and implement changes that satisfy the court order. The company can either roll out an official third-party marketplace API or provide clear sideloading guidance for developers. Failure to comply could lead to additional fines or oversight from regulators.

Broader Impact on App Store Competition

This ruling is a landmark for platform competition and may inspire similar challenges worldwide. By opening the gate for rival marketplaces, regulators signal they expect more balance between platform control and developer autonomy. Tech leaders should monitor regional responses and prepare adaptive distribution strategies to stay ahead.
