“We invest a lot of money here in China,” proclaimed Travis Kalanick, founder and then boss of Uber, at a confab in Tianjin in June 2016. But, he added with foreboding, “we have a competitor who is investing even more.” Two months later the American ride-hailing giant threw in the towel, selling its Chinese operations to its Beijing-based rival, Didi. Uber lost some US$2 billion over two years in China. Its retreat paved the way for Didi to grow into China’s undisputed ride-hailing champion, which today processes over four-fifths of all domestic orders. The Chinese titan is widely expected to go public in the next few months, eight years after its launch. It could fetch a valuation of US$60b.
