> The round was said to have raised the four-year-old startup’s valuation to about $50 billion, up from a previous $34 billion after its acquisition of Uber’s China business.

Uber's valuation is ~$70 billion while Lyft's valuation is less than $10 billion. Therefore it seems like the two main players in ride-sharing will be Uber and Didi for the next while.

I can see Didi branching towards other markets (outside of China) and directly competing with Uber and Lyft. This will be interesting in the next while.
