Alipay, or Zhifubao in Chinese, is a third-party mobile and online payment platform, established in Hangzhou, China in February 2004 by Alibaba Group and its founder Jack Ma. In 2015, Alipay moved its headquarters to Pudong, Shanghai, although its parent company Ant Financial remains Hangzhou-based.

Alipay overtook PayPal as the world’s largest mobile payment platform in 2013. In the fourth quarter of 2016, Alipay had a 54% share of China’s US$5.5 trillion mobile payment market, by far the largest in the world, although its share fell from 71% in 2015 as its rival Tencent’s WeChat Pay was rapidly catching up.
