The WNBA Has 15 Teams Now. Its Playoffs Are Showing What Expansion Changes

The WNBA grew from 13 teams to 15 this season, and its postseason still has eight spots. That simple piece of arithmetic is the most interesting thing about the 2026 playoffs, and it's worth doing the maths on.

In a 13-team league, eight playoff places meant about 62 percent of teams qualified. With 15 teams, it's about 53 percent. The league added two clubs and made the door slightly narrower.

Who's new, and who's in

The additions were the Portland Fire and the Toronto Tempo, and Toronto is the first WNBA team based outside the United States. Both missed the postseason. That's not a surprise for two brand-new rosters built from an expansion draft, and it's certainly not a failure.

The field that made it is a mix of the established and the recently arrived. The Minnesota Lynx are the top seed, and Golden State, an expansion team from 2025, is a top-four seed with home-court advantage in the first round. The defending champion Las Vegas Aces are there, along with the Atlanta Dream, the Indiana Fever, the Washington Mystics, the Dallas Wings and the New York Liberty.

That Golden State is in that group is worth pausing on. A team that played its first game only last year is hosting playoff games while two even newer clubs watch from home. It suggests the league's model for launching teams can work quickly when the roster and the market line up.

What the format does

The playoffs run through a best-of-three first round, a best-of-five semifinal and, for the second time in league history, a best-of-seven Finals. The first round is the harshest part, and Sunday showed it. The Liberty, the eighth seed, beat the top-seeded Lynx in Game 1 behind Breanna Stewart's 34 points.

That result didn't come from a bracket quirk. New York was 26-18 in a 44-game season, and the Lynx were 33-11. It shows how narrow the gap between first and eighth can be when the eighth seed has one of the best players in the world, and how little a top seed can afford to slip in a series that can end after two games.

Other Game 1s were less dramatic. The Aces, Valkyries and Dream all took early leads, and Las Vegas's A'ja Wilson scored 38 against Indiana. Three of the four higher seeds were winning. The one exception got the headlines.

Was keeping eight the right call?

The league has effectively answered the expansion question by not changing the playoff field, and Sunday made a decent case for the decision. A smaller share of teams qualifying makes the regular season matter more. Every one of the eight teams that made it is a plausible contender, and the top seed can be beaten by a team that finished with 18 losses.

There's a counterargument, and it's fair. A 44-game season is short, and a first round of only three games makes it easy for a single bad night to undo it. The Lynx spent six months earning the top seed and were 0-1 within an afternoon. Minnesota is 0-3 in franchise history after losing Game 1 of a best-of-three.

The other question is what happens as the league grows. Fifteen teams is a big number, and the WNBA has shown no sign of stopping. If the league adds another club or two, the pressure to widen the postseason will build, especially from owners in markets that keep just missing the cut.

For now, though, the playoff field looks like a group of teams that earned their places. Expansion hasn't diluted the competition at the top. It's spread the talent, and the bottom of the bracket is now full of players who can beat anybody.

How many teams should a 15-team league send to the playoffs: eight, ten or something else entirely?
