On June 30, 2025, the WNBA announced that it would expand to Cleveland, Detroit, and Philadelphia, bringing the total to 18 teams. Cleveland and Detroit previously were WNBA markets.

Background

The WNBA's exponential growth and popularity in recent years has led to rising expansion fees. The Golden State Valkyries, the league’s 13th franchise that began play in May 2025, paid $50 million to join, while the Toronto Tempo and Portland Fire — the 14th and 15th franchises scheduled to begin play in 2026 — paid $115 million and $125 million, respectively.
The deadline for the next expansion bids was January 30, 2025. At the time, the bids were believed to be for a 16th expansion team. League commissioner Cathy Engelbert had said she was aiming to have the league expand to 16 teams by 2028. However, as expansion fees continued to rise, the league rethought its original plan of adding just one more expansion team. Each new team will pay $250 million in franchise fees to join the league.

Cleveland

was previously home to the Rockers, one of the WNBA’s original eight members when the league began play in 1997. However, the franchise folded after the 2003 season when former owner Gordon Gund could not sell the team due to tumbling revenue and erratic attendance.
The new team will play at Rocket Arena, home of the National Basketball Association's Cleveland Cavaliers. The WNBA filed a trademark application for the name “Cleveland Rockers”, a potential sign of the league’s intentions to revive the team name.

Detroit

was previously home to the Shock, one of the WNBA’s first expansion teams when it began play in 1998. Between 1998 and 2009, the Shock won three WNBA championships. However, the team’s low fan attendance led the franchise to relocate to Tulsa, Oklahoma, in 2009, where it played until 2015. The franchise moved again in 2015, to Arlington, Texas, and are now called the Dallas Wings.
The new team will play at Little Caesars Arena, home of the NBA's Detroit Pistons. The WNBA coincidentally filed a trademark application for the name “Detroit Shock” the same day Tom Gores, owner of the Pistons, submitted his offer for a WNBA expansion team, a potential sign of the league’s intentions to revive the team name.

Philadelphia

owner Josh Harris of Harris Blitzer Sports & Entertainment, which also owns the New Jersey Devils of the National Hockey League, submitted a bid for an expansion team. When Harris partnered with Comcast on a new arena in South Philadelphia, the priority was to house a WNBA team along with the NBA's Philadelphia 76ers and the NHL's Philadelphia Flyers.
