It's obviously a different context globally, due to regulations, nationalism, et al. Didi for example will never own the US market, they're likely to end up like other Chinese tech giants, struggling to dominate internationally as they do domestically.
Ola is the next Flipkart.
Because they have a lot more money and will remain standing as an independent entity. Prices will either rise, or Uber will remove costs via autonomous driving (they're hoping to get there before they have to hike prices, because if they get there in time, it becomes a very difficult to overcome moat and they win).
Amazon nearly went bankrupt on their hyper thin margins early on. Had the dotcom bubble popped just a bit sooner, they'd have gone under. They were bleeding red ink trying to get to scale before the easy money ran out. Uber is trying to do a similar thing, fortunately for them the asset bubble party has continued on long enough for them to raise a vast warchest of cash.
Lyft, which is still experiencing 100% growth year-over-year?
Didi, which dominates the Chinese market?
Ola, which matches Uber in India?
Grab, which dominates in Malaysia and is experiencing large growth in Southeast Asia?
Didi, Lyft, and Uber are all nearing the point where they can't dump subsidies on the market; they have to raise rates or they won't raise more money. They have to become profitable soon. When they become public companies, they won't be able to lower rates at the expense of profits without raising the ire of shareholders.
By the way, the entire European market is open to the ride sharing company who can be palatable to EU governments. Uber is failing at this; the opportunity is very much there.
