Why Is Uber Worth Another Billion Dollars?

Uber is raising more money as it expands its business beyond having cars on call. The tech news site Re/code reports that Uber has a messenger service in New York, an experiment in delivering household goods in Washington D.C. and another experiment in food delivery in Southern California. And Uber recently hired the head of Google Express same-day service.

But Uber still faces a set of legal challenges, as well as stiff competition in all of those ventures, from companies including Lyft, Hailo and Sidecar in the taxi business. So why do analysts think that investors will gamble another billion on Uber?
