I just don't get it. Who's buying this stock and why do they think that a company that is not profitable during a pandemic, with people locked in their homes and in-person dining outlawed, is going to be worth billions of dollars? There's no loyalty in food delivery. Everybody is chasing the same promos. There's no moat. Just VC funded revenue.
DoorDash doesn’t intend to be a “food delivery company”. Listen to their CEO in interviews. His catch phrase is that if you solve food delivery, you solve some of the most challenging aspects of last-mile logistics. I expect they will transition away from food and into other verticals soon.
That's ... that's not a solution.
UPS famously hired mathematicians to figure out the optimal way to plan their trucks' routes [1]. Now that is a solution.
