Amazon’s leading position in U.S. e-commerce is well-documented, but the latest global rankings for app installs show the potential for newer brands to upend the online shopping juggernaut.

The tech giant ranked fourth globally in shopping app installations for 2021, according to new data from Apptopia. Amazon topped the worldwide ranking last year, as measured by the real-time competitive intelligence platform.

Three e-commerce companies leapfrogged Amazon in the global rankings: Shopee, based in Singapore, which serves Southeast Asia and Latin America; Shein, based in China, a leader in “fast fashion”; and Meesho, based in India, which specializes in social e-commerce for categories including fashion and home products.

Amazon is still first in Apptopia’s U.S. rankings for shopping app installs in 2021.

Responding to regulators in the U.S. and elsewhere, Amazon executives have repeatedly made the case that the company’s small share of the global retail market, including online and offline sales, falls short of the market power that would warrant aggressive antitrust action.

However, as of a few months ago, Amazon was expected to account for more than 40% of U.S. e-commerce sales in 2021, according to eMarketer.
