Denver Summit's home opener against Washington Spirit shattered the NWSL's single-game attendance record, signaling massive demand for women's soccer in a new market. The expansion team's ability to draw record crowds immediately validates the league's growth strategy and the economics of adding franchises to underserved metros. NWSL expansion fees have climbed sharply — recent additions paid $110M+ to enter the league. Denver's record-breaking debut suggests those valuations aren't overpriced. Strong attendance translates directly to media rights leverage, sponsorship renewals, and ownership returns in the next TV negotiation cycle.
