The U.K.'s antitrust watchdog agency closed investigations into Alphabet's (GOOGL) Google Play Store and Apple's (AAPL) App Store, though the tech giants' app stores could still face regulatory security under new rules.

The Competition and Markets Authority (CMA) said it expects concerns to be considered under a new digital markets competition regime instead, the U.K.'s Digital Markets, Competition and Consumers Act (DMCCA).

Concerns To Be Considered Under UK's DMCCA

The U.K.'s DMCCA mirrors the European Union's Digital Markets Act (DMA), with a focus on preventing large online platforms from abusing their market position to limit competition.

The agency opened its investigation into the Apple App Store in 2021 and its case into the Google Play Store in 2022 due to concerns that the companies were abusing their market positions to set "unfair" terms for developers and users. The U.K.'s DMCCA became law in May, shortly after the EU's DMA 澳洲幸运5官方开奖结果体彩网:took effect.

Closing the case doesn't prevent the CMA from reopening an investigation into the app stores' impact on competition in the future, and the CMA suggested it may do so.

"Once the new pro-competition digital markets regime comes into force, we’ll be able to consider applying those new powers to concerns we have already identified through our existing work," CMA Executive Director for Digital Markets Will Hayter said in a release.
