Using staggered entry of two dockless bike‐sharing firms, we study whether the entrant expands or steals the market from the incumbent in 59 cities. Compared with 23 cities without entry, the entry helps the incumbent to serve more trips, make more bike investment, achieve higher revenue per trip, improve bike utilization, and form a wider and more dispersed network. The market‐expanding effect on new users dominates a significant market‐stealing effect on old users. These findings, plus a theory that highlights consumer search and network effects, suggest that a market with positive network effects and multihoming users is not necessarily winner‐takes‐all.
