Apple is facing a major legal challenge in the United Kingdom after the Competition Appeal Tribunal approved a £3 billion ($4 billion) class action lawsuit accusing the technology giant of abusing its market position through its iCloud storage service. The ruling allows the case to proceed on behalf of nearly 40 million UK consumers who used iCloud between November 2018 and June 2026.
The lawsuit was filed by UK consumer rights organization Which?, which alleges that Apple used technical restrictions, system design features, and prompts within its ecosystem to make it difficult for users of iPhones, iPads, and other Apple devices to switch to competing cloud storage providers. According to the claim, these practices reduced competition and resulted in consumers paying higher prices for cloud storage services, Reuters news report said.
The Competition Appeal Tribunal rejected Apple’s attempt to block portions of the lawsuit and granted a Collective Proceedings Order, allowing Which? to represent affected users in a collective action. The legal action could become one of the largest competition-related consumer cases in the UK technology sector.
Which? estimates total damages at approximately £3 billion, with eligible consumers potentially receiving compensation of up to £77 each if the case succeeds. The claim covers almost 40 million UK iCloud users, highlighting the scale of the legal challenge facing Apple.
At the center of the dispute is the allegation that Apple leveraged its dominance in mobile devices to favor iCloud over rival cloud storage platforms. The consumer group argues that Apple effectively “locked in” users by integrating iCloud deeply into its operating system while limiting the convenience and functionality of competing services.
Apple has strongly denied the allegations. The company maintains that iCloud is an optional service and that customers have access to numerous alternative cloud storage providers. Apple said the claims are unfounded and emphasized that users are not required to use iCloud on their devices.
The tribunal’s decision does not determine whether Apple violated competition laws. Instead, it clears the way for a full trial, which is currently expected to take place in 2028. The outcome could have significant implications for how large technology companies manage digital ecosystems, cloud services, and customer choice in regulated markets. The case adds to growing global scrutiny of major technology platforms, as regulators and consumer groups increasingly examine whether tightly integrated ecosystems create barriers to competition. For Apple, the iCloud lawsuit represents another high-profile legal battle at a time when governments worldwide are intensifying oversight of digital markets and platform dominance.
