Alibaba and JD.com have been in a war over the Chinese e-commerce space for a decade or so, but a third player called Pinduoduo has managed to shake up the duopoly in recent times. The startup, which was founded in 2015 by an ex-Googler and went public on the Nasdaq last July, has further flexed muscles during the recent “6/18” shopping spree. According to data provider QuestMobile, Pinduoduo’s daily active users have outnumbered JD’s for at least the past 12 months, and it came out of the mid-year sales festival — first popularized by JD as a counterpart to archrival Alibaba’s “11/11” shopping day — with 135 million DAUs. JD, in comparison, ended with 88 million DAUs and Alibaba’s Taobao retained its top spot at 299 million.
