The WNBA championship format has changed considerably over the league’s history. The 1997 season was decided by a single championship game. The Finals became a best-of-three series in 1998 and remained that way through 2004, before changing to a best-of-five format in 2005. Beginning in 2025, the WNBA Finals moved to a best-of-seven format.

The Houston Comets established the league’s first dynasty, winning the first four WNBA championships from 1997 through 2000. The Comets remain one of three franchises with four championships, alongside the Minnesota Lynx and Seattle Storm.

The Seattle Storm won championships in 2004, 2010, 2018, and 2020, while the Minnesota Lynx captured titles in 2011, 2013, 2015, and 2017. The Las Vegas Aces joined the group after winning championships in 2022, 2023, and 2025.

The 2025 WNBA Finals marked another major change in league history. Las Vegas defeated Phoenix 4–0, becoming the first WNBA champion to win a Finals series under the new best-of-seven format. A’ja Wilson was named Finals MVP.

The WNBA’s historical record continues to expand with new franchises, players, statistical milestones, and championship contenders. HeatingUp’s WNBA archive provides season-by-season standings and historical information dating back to the league’s inaugural 1997 season.
