PDD Holdings operates two primary e-commerce platforms: Pinduoduo, a mobile-centric marketplace in China launched in 2015 that emphasizes social commerce and group-buying mechanics to offer consumers lower prices through volume aggregation, and Temu, a global e-commerce platform that brings together consumers, merchants, and brands across multiple international markets. The company also operates Duo Duo Grocery, a next-day grocery pickup service. PDD generates revenue primarily through online marketing services where merchants pay for promotional listings, transaction commissions from platform sales, and other value-added services, connecting buyers seeking affordable products with independent merchants who source, price, and sell items directly while leveraging the platforms' infrastructure for payment processing, logistics coordination, and dispute resolution.
