Network effects and driver supply create a moat that capital alone cannot breach. New entrants need critical mass of both riders and drivers simultaneously, but neither side joins until the other is already there. Uber and Lyft can subsidize rides and driver incentives indefinitely while newer competitors burn cash trying to achieve the same density. Venture-backed competition becomes structurally difficult without radical differentiation—geography, pricing model, or user segment—that existing players can copy or crush. This explains rideshare consolidation into a two-player system despite billions in venture funding chasing disruption.
