Epic Games v. Apple

Apple takes up to a 30% cut on many in-app purchases and requires developers to use its billing system. Epic argued that combo—only App Store distribution plus mandatory Apple payment—illegally blocked competition.

Epic staged a public confrontation by offering cheaper V-Bucks through Epic's own checkout, knowing Apple would remove Fortnite. The lawsuit followed immediately.

After a high-profile trial, the judge ruled Apple is not a monopolist under federal antitrust standards in the relevant markets Epic proposed, and its security and privacy justifications carried weight.

Still, the court barred Apple from preventing developers from communicating about external payment options in specific ways under California's unfair competition law—a partial opening Epic and others cited in later regulatory pushes.

US courts set a high bar for calling mobile app stores illegal monopolies.

Developer fights over 30% commissions influenced legislation in the EU, South Korea, and US states.

The case shows platform owners can win on antitrust yet still face state-law and regulatory pressure.

Apple monopolized iOS app distribution and in-app payment processing.

Tying Fortnite access to Apple's payment system harmed competition and consumers.

Apple's rules were exclusionary, not merely business terms.

Apple said Epic breached a contract and that the App Store's curation and security benefit users.

Apple argued competition from Android and web apps prevents monopoly power.

Apple maintained its commission funds a trusted marketplace and developer tools.

Fortnite returned to iOS through alternative channels in some regions, not a full US App Store policy overhaul.

US iPhone users did not gain sideloading or third-party app stores from this case alone.

EU and other jurisdictions pursued broader App Store changes separately.
