The governing board of Major League Soccer has approved a shift from a calendar-year to a summer-to-spring schedule. The new format will begin in 2027 with an abbreviated season running from February to May.

The 2027 season will crown an MLS Cup champion before the league transitions to a full summer-to-spring calendar. The change aims to align with international transfer windows and improve global player movement.

The league will maintain the U.S. Open Cup, Canadian Championship, and Leagues Cup as part of the new structure. The MLS Players Association continues to negotiate details, particularly around offseason length and schedule certainty.
