Apple (NASDAQ:AAPL) shares were down 2.67% to $226.58 in premarket trading as of 5:34 AM ET Wednesday following reports that China’s State Administration for Market Regulation is considering an investigation into the company’s App Store policies and fees.

The antitrust regulator has been reviewing Apple’s commission structure, which includes charging developers up to 30% on in-app purchases and restricting third-party payment services. Officials have been in discussions with Apple executives and developers since last year, Bloomberg News reported.

China’s scrutiny follows increasing pressure on U.S. tech firms, with recent regulatory actions against companies like Nvidia (NVDA) and Alphabet’s (GOOGL) Google. While an investigation isn’t certain, regulators believe Apple’s policies may be unfair to local developers and consumers.

Apple is already facing global regulatory challenges, including in the EU and UK. In fiscal Q1 2025, iPhone sales in China dropped 11% year-over-year to $18 billion, with Apple losing its top market position to local brands like Vivo and Huawei.
