EXPANSION WATCH · THE W

THE W GETS WIDER

The official growth map now has two different kinds of movement: Houston returns in 2027 through the Connecticut Sun relocation, then Cleveland, Detroit and Philadelphia add new franchises on the road to 18 teams.

2027 · RELOCATION, NOT EXPANSIONHouston Comets: the dynasty returns.

The WNBA and NBA Boards of Governors unanimously approved the sale and relocation of the Connecticut Sun to Houston for the 2027 season. The Comets will play at Toyota Center under Fertitta Entertainment. Because an existing franchise is moving, the league remains at 15 teams in 2027.

Why this matters to Expansion Watch

The market changes, but the team count does not. The Sun finish 2026 in Connecticut, then the franchise moves to Houston. Connecticut says Houston receives the rights to any player and coach contracts still held at handoff, so there is no separate Houston expansion draft.

THE ROAD TO 18Three new franchises follow Houston's move.

Cleveland arrives in 2028 as the 16th team, Detroit in 2029 as the 17th and Philadelphia in 2030 as the 18th, following Golden State, Toronto and Portland in the league’s current expansion era.

EMPTY ROSTER → REAL TEAM

Relocation and expansion build rosters differently.

Cleveland, Detroit and Philadelphia will need expansion-roster mechanics. Houston inherits an existing franchise's contract rights and then uses normal trades, free agency and the draft to shape its 2027 team.
