Major League Soccer has extended its 2026 summer transfer window, moving the closing date to September 2, aligning it with major European leagues for the first time. This addresses past challenges caused by earlier MLS deadlines (August 14 in 2024, August 21 in 2025).
Key points:
- Summer window: Opens July 12, closes September 2, 2026
- Winter window: Opens January 26, closes March 26 (shortened to allow a longer summer window)
- Canadian MLS clubs (CF Montréal, Toronto FC, Vancouver Whitecaps FC) are now permitted by FIFA to follow U.S. Soccer’s registration periods, eliminating earlier mismatched deadlines
- Change is widely supported by MLS sporting directors to better sync with the European transfer market, ahead of a full calendar shift in 2027
- Concacaf Champions Cup begins February 3; MLS regular season starts February 21
- Roster compliance deadline: February 20 (salary cap)
- Roster freeze: October 9
- Clubs may still sign free agents after the transfer window closes until the roster freeze
Overall, the adjustment is a strategic move to improve roster flexibility, international competitiveness, and market alignment—especially important following the 2026 World Cup.
