Uber market cap makes places it in the top100 in the world, whereas Lyft is around 1/25th of Uber in market cap, and not even top1000. I would consider that a success... That is basically as much winner-takes-it-all one can realistically get in a global market. Cases where the top is just 5x the runner up would still be very winner oriented.

And in Europe Bolt is winning in many markets.

Taxi apps are a commodity today.
