A new infrastructure study maps the revenue women's sports leagues are leaving on the table by playing in shared arenas. The estimate: more than $1 billion annually across top-tier leagues if they controlled their own venues. The gap is not attendance—it is inventory.
Women's leagues currently rent from NBA, NHL, or MLS landlords, which means they get secondary access to premium suites, club seats, and concourse sponsorship zones. The National Women's Soccer League plays in 12 different stadium types, from MLS-shared facilities to college grounds to minor-league baseball parks. The WNBA shares 11 of 12 arenas with NBA tenants. Scheduling flexibility is limited, brand control is fractional, and year-round activation is structurally impossible when the landlord controls the calendar.
The $1 billion thesis rests on three revenue streams that require facility ownership: premium seating inventory sold on annual contracts rather than single-game rental rates, year-round naming rights and sponsorship exclusivity, and proprietary fan data from ticketing and retail that currently flows to the primary tenant. The report draws comparisons to MLS, which shifted from shared NFL stadiums to soccer-specific venues starting in the early 2000s. MLS franchise values were below $50 million in 2005; today they average $585 million, and the league credits purpose-built stadiums as the primary driver. Soccer-specific venues allowed MLS to control sightlines, build intimate capacities (18,000–25,000 seats) that sold out consistently, and capture sponsorship categories that NFL stadiums had already locked up.
Women's soccer is closest to executing this model. The NWSL's San Diego Wave opened Snapdragon Stadium in 2022, a 35,000-seat venue shared with San Diego State football but designed with sightlines optimized for soccer. The Wave drew an average of 19,167 fans per match in their first season, the highest in NWSL history, and sold 12,000 season tickets before kicking a ball. The team's valuation is now estimated near $120 million, roughly double the league average. Bay FC is building its own training facility and front-office campus in San Jose, signaling similar ambitions.
The WNBA faces a different constraint. Basketball arenas are expensive, and the league's average attendance—9,807 in 2024—does not yet justify 18,000-seat builds. But the report suggests a hybrid path: leagues could anchor smaller, 8,000–12,000-seat arenas in secondary markets, co-locating with training facilities and front-office space to create year-round campuses. The economic model shifts from game-day rental fees to asset ownership, which unlocks debt financing, real estate appreciation, and control over non-game revenue (concerts, youth tournaments, sponsorship events).
Two obstacles remain. First, capital. Purpose-built stadiums cost $150 million to $400 million depending on capacity and market. Women's leagues are still majority venture-backed, and institutional sports investors have historically required anchor tenants (NFL, NBA) before financing arenas. Second, market selection. MLS succeeded by targeting Sun Belt metros with low land costs and corporate sponsor density. Women's leagues are concentrated in legacy coastal markets where real estate is prohibitively expensive and existing facilities are entrenched.
The NWSL will test the model first. The league is in active expansion talks for two more franchises, and prospective ownership groups in Cleveland, Cincinnati, and Milwaukee are reportedly exploring stadium deals with public-private partnership structures. The league's new media rights deal with ESPN, CBS, and Amazon—worth $240 million over four years—provides revenue certainty that lenders require for project financing.
The WNBA's path is slower but parallel. Commissioner Cathy Engelbert has said the league will expand to 15 or 16 teams by 2028, and new franchises in Portland, Toronto, and the Bay Area are expected. None have announced stadium plans, but the business case is sharpening. The Golden State Valkyries, launching in 2025, will play at Chase Center, but the team has already begun discussions about a smaller East Bay venue for future seasons.
The $1 billion figure is extrapolated across leagues, but the mechanism is specific: women's sports need to stop being tenants. The revenue is not hypothetical—it is currently being collected by someone else.
Watch for NWSL expansion announcements tied to stadium commitments in the next six months, and for whether the Valkyries or another WNBA expansion team is the first to break the shared-arena model. The league's collective bargaining agreement expires in 2027, and facility control will be a negotiating priority for players who understand that revenue growth requires infrastructure ownership.
