The Reign spent eight weeks away from their home stadium, Lumen Field, due to the 2025 FIFA Club World Cup and a league-wide break in the regular season. The team returned to Lumen Field in July for a friendly against the Urawa Red Diamonds.
The NWSL announced the 2025 regular season schedule on January 22, 2025.
The Reign clinched a playoffs spot after a home win against Utah Royals in the penultimate match of the regular season on October 17.
