Uber matches riders with drivers and eaters with couriers across tens of thousands of cities, running the world's largest ride-hailing network alongside the Uber Eats delivery business and a freight brokerage. The company owns no vehicles; its asset is the two-sided network, where more drivers mean shorter waits and more riders mean better earnings, a loop that punishes smaller challengers. Membership through Uber One and advertising add higher-margin layers. After years of subsidized growth, the model crossed into sustained profitability.
