A significant lawsuit between Apple and Epic Games could offer hints for what Big Tech’s relationship with antitrust could look like down the road. Apple and Epic Games began their trial on May 3, opening what is estimated to be a three-week trial for the two companies.

The lawsuit in question relates directly to Apple’s supposed monopoly on iOS apps. In August 2020, Epic Games decided to allow Fortnite players to save money by purchasing V-Bucks, the in-game currency, through Epic Games. By buying directly from Epic Games, the Fortnite creator cut out the middleman of Apple. The latter takes a 30% fee of any transactions completed in the iOS marketplace.
