Uber is apparently already profitable in the US. Does anyone know if Lyft is? If it is not, then that would suggest that Lyft is more guilty than Uber of subsidizing rides in order to win market share.

    2016 numbers:

    Lyft Revenue: $700 million
    Lyft Losses: $600 million
    Uber Revenue: $6 billion
    Uber Losses: $2.8 billion

The ratio of revenue to losses suggest that Uber is almost twice as efficient as Lyft, and Uber's losses are probably further compounded as it includes many more future investments such as international markets that aren't yet as mature as the US market, and products/services that for which Lyft has no comparable offering like UberRush and UberEats. Lyft also doesn't have any investment in self-driving cars that I'm aware of.
