Uber is currently engaged in a war of attrition with China’s largest ride-sharing company, Didi Kuaidi, and it’s costing the company more than $1 billion a year, according to CEO Travis Kalanick. We’ve known that Uber is losing a lot of money in China, but we didn’t know how much until now. According to Kalanick, Didi Kuaidi is losing tons of money as well, so it’s really a matter of which company can raise the most funding and secure the most market share until one of them ends up leaving the market. Uber is still profitable in the United States though, so it’s not all that bad.
