Amazon made $2.62 billion in the last quarter, and $3.5 billion the quarter before that.

Amazon makes a ton of money, and (quite transparently I might add) they plow a lot of their earnings from some of their businesses into investing into their other businesses, which is what most investors want.

This is completely different from Uber and Lyft, where it's not clear that their profit potential supports their current valuations.
