CMA strategic market status — Apple mobile

2025–present · mobile operating systems, app distribution

The UK regulator opened a strategic-market case on Apple's mobile platform in 2025. In 2026 it was still about whether to designate Apple and what rules would follow. It is not the EU fine and not the US lawsuit.

The story

Britain's new digital-markets law is a conduct regime. The CMA opened an Apple investigation alongside Google.

The topics are the familiar ones: the App Store, the browser, and how closed the phone is.

Until a conduct requirement is published and in force, UK iPhones follow Apple's current rules.

Why it matters

A UK conduct rule can diverge from both Brussels and Washington.

Developers who ship to the UK care about the store terms that result.

What was claimed

That Apple's mobile platform may warrant strategic market status.

Not a claim for damages.

The other side

Apple says iOS competition happens between platforms and that UK rules should not copy the DMA's disputes.

What it means for you

No UK-only sideloading mandate follows just from the investigation opening.

Bottom line

The UK SMS case on Apple's mobile platform is open and unfinished.

Formal snapshot

Summary: The CMA opened a strategic market status investigation into Apple's mobile platform under the UK digital markets law. It is separate from EU DMA fines and from the US smartphone case.

Regulator / plaintiff argument: Apple's control of iOS distribution and defaults may be entrenched enough for UK conduct requirements on stores, browsers, and interoperability.

Outcome: Opened in 2025. As with the Google search SMS file, designation and conduct requirements were still the work in progress through 2026. No UK fine in this file.
