Major League Soccer (MLS) has unequivocally confirmed the full participation of all 27 U.S.-based clubs in the 2027 Lamar Hunt U.S. Open Cup. The announcement, made on September 2, 2026, ushers in a significant overhaul to the nation's oldest ongoing football competition, promising an enhanced and more competitive tournament structure.
New Format Elevates MLS Involvement
Under the newly adopted format, MLS clubs will now make their entry into the U.S. Open Cup in the Round of 64, scheduled for July. This represents a later entry point for the top-tier domestic clubs, potentially creating more compelling matchups deeper into the tournament.
A key aspect of this revised structure grants MLS clubs priority to host their opening matches. This could provide a crucial home-field advantage as they embark on their cup journey. Furthermore, game day rosters for all participating teams will be expanded from 18 to 20 players, offering coaches greater tactical flexibility and squad rotation options, which will be particularly vital during congested schedules.
Key Dates for the 2027 Tournament
The 2027 U.S. Open Cup will feature a condensed, high-stakes schedule following the initial rounds. Mark your calendars for these pivotal dates:
- Round of 32: September 14-15
- Quarterfinals: November 23-24
- Semifinals: December 1
- Final: December 15
This concentrated schedule ensures a rapid progression through the knockout stages, building anticipation towards the crowning of a champion in mid-December.
Betting Angle: Analyzing the Impact on Futures and Match Odds
For bettors, the full MLS participation and late entry create intriguing new dynamics. The later entry for MLS clubs could shift the soccer odds significantly. While MLS teams will likely enter as strong favorites in their initial Round of 64 matches against lower-division opponents, the concentrated schedule in the later rounds, coupled with expanded rosters, suggests a greater emphasis on squad depth and strategic rotation.
This revised format may offer enhanced opportunities for value. Punters might look for early-round upsets against lower-division teams with home advantage, or conversely, strong moneyline bets on well-rested MLS sides as they enter the fray. The expanded roster allows for more strategic substitutions, which savvy bettors will need to factor into their pre-match analysis. Monitoring team news for rotation patterns will be more crucial than ever as the tournament progresses towards its dramatic conclusion.
The commitment from MLS to full participation signals a renewed focus on the U.S. Open Cup's prestige and competitive integrity. As the 2027 tournament approaches, fans and bettors alike will be keenly watching how this new format unfolds and shapes the future of American club football.
