Kind of a hot take, but this is why I'm long Uber. They're processing an insane amount of orders, and getting a huge amount of people using their app. If Lyft dies, or if a merger occurs, then we have a large ride share company that is still a lot more than 10% better than taxis. Most customers will still be taking Ubers, regardless of that 10% price hike.
Of course, this is just for the ride share business. I don't see how food delivery will be profitable long-term. Maybe it'll be just a loss leader for them?
