The Open Cup future changed direction on September 2, 2026, when Major League Soccer announced that all 27 U.S.-based MLS clubs would compete in the 2027 Lamar Hunt U.S. Open Cup. That decision restored full MLS first-team involvement for the first time since 2023 and placed the national knockout competition back into the competitive calendar of every U.S.-based top-flight club.
For a competition built on cross-division access, that matters beyond one entry list. The 2027 edition is scheduled to connect MLS clubs, USL Championship teams, USL League One teams, MLS NEXT Pro sides, and Open Division qualifiers in a 96-team field. It also gives clubs a direct cup target at a time when MLS is adjusting its calendar and squad-management model.
The change is not only symbolic. MLS clubs are scheduled to enter in the Round of 64 from July 8-11, 2027, with hosting priority for their first match, according to the MLS announcement. That places the competition in a clearer window and gives each MLS team a defined starting point.
Why The Open Cup Future Matters To MLS Clubs
MLS clubs have long balanced domestic league play, cup competition, player development, and continental qualification. The 2027 Open Cup structure makes that balance more formal. Every U.S.-based MLS club has a route into the same national bracket, rather than a partial-entry model that separated first teams from the tournament.
Open Cup Future And MLS Entry Rules
The Round of 64 entry point is important because it reduces uncertainty for sporting departments. Clubs know the first Open Cup window is scheduled for July 8-11, 2027, and can build roster plans around that period. The first-match hosting priority for MLS clubs also affects preparation, travel, and venue planning, even though knockout competition can still create uneven competitive demands from round to round.
The format gives MLS clubs a direct national-cup obligation while still preserving the tournament’s broader pyramid connection. Lower-division professional clubs and amateur qualifiers remain central to the competition’s identity. The Open Division’s 32 amateur places are especially significant because they maintain the cup’s traditional route for clubs outside the professional leagues.
The Open Cup future also sits beside larger MLS schedule questions. The league’s regular season is transitioning to a summer-to-spring competition calendar for 2027-28, and the 2027 Open Cup timing was designed to fit that move. For a league that has often operated differently from many global football calendars, a more aligned cup window could help clubs plan across league, cup, and international dates.
Why Full Participation Carries Competitive Weight
Full participation gives the tournament a clearer sporting hierarchy. If all U.S.-based MLS clubs enter, the competition can again function as a national test across divisions. Upsets, rotated lineups, and away matches in difficult environments are part of the appeal, but the tournament’s record book gains more weight when every eligible top-flight club is in the field.
For MLS clubs, silverware is the direct prize, but the value is wider. The winner is set to receive a $1 million purse and qualify for the 2027 Concacaf Champions Cup. That continental berth makes the competition more than a midweek squad exercise. It creates a pathway into international club competition through a knockout format rather than a league-table finish.
How The 2027 Format Reshapes The Competition
The 2027 Lamar Hunt U.S. Open Cup is scheduled as a 96-team tournament. The field is set to include 27 MLS Division I clubs, professional teams from USL Championship, USL League One, and MLS NEXT Pro, plus 32 amateur Open Division teams. MLS NEXT Pro also stated that players from 28 of its teams would be able to compete in the tournament framework, according to MLS NEXT Pro.
| 2027 Element | Supported Detail | MLS Impact |
|---|---|---|
| Field Size | 96 teams | Wider national bracket |
| MLS Entry | Round of 64, July 8-11, 2027 | Defined start point for all U.S.-based clubs |
| MLS Clubs | 27 U.S.-based first teams | Full top-flight participation restored |
| Late Rounds | Round of 32 onward after Labor Day | More decisive matches later in the calendar |
| Final | December 15, 2027, subject to change | End-of-year cup climax |
Late-Round Timing Creates A Different Rhythm
The scheduling choice to place the final five rounds, from the Round of 32 onward, after Labor Day changes the feel of the competition. Instead of compressing key rounds into the earliest part of the MLS calendar, the tournament is scheduled to build toward late-season tension. That gives the cup a separate identity during a crowded football year.
The final is scheduled for December 15, 2027, subject to change. That date would make the Open Cup a late-year title match, with clubs potentially managing league objectives, cup ambitions, and player availability in a more demanding period. For clubs with deeper rosters, that timing may reward squad depth. For smaller clubs, it may increase the value of fitness, continuity, and tactical clarity.
How Clubs Can Plan The Open Cup Future
Roster rules are central to how MLS teams will treat the competition. Game day rosters are set to expand from 18 to 20 players, and MLS clubs may use players from the first team, MLS NEXT Pro, and academy ranks. That flexibility matters because clubs can protect senior players, reward form from the development pathway, and still field competitive lineups.
Player Development Without Separating The First Team
The Open Cup future is not only about established starters. The 2027 model allows clubs to connect academy players, MLS NEXT Pro players, and first-team professionals inside one competitive structure. For young players, cup minutes can carry more pressure than reserve-level matches because the result affects the senior club’s season.
That pathway can also improve evaluation. Coaches can see how developing players respond against different opponents, from lower-division professionals to MLS rivals. The single-elimination format leaves less room for slow adaptation. A young midfielder asked to close space, a center-back defending direct play, or a forward facing a compact lower-division block receives a practical test that training alone cannot recreate.
For clubs with long-term roster plans, the cup can serve as a bridge. It can help identify players ready for more league minutes and players who still need development time. It can also create shared stakes across an organization, because academy and MLS NEXT Pro players are no longer separated from the first-team cup objective.
Why The Cup Still Matters In A Crowded MLS Calendar
Fixture congestion is the main practical challenge. MLS teams already operate across league play, Leagues Cup, potential Concacaf competition, and international call-up windows. The Open Cup adds another competitive path, but the 2027 design attempts to reduce some conflicts by moving the decisive rounds later and aligning the entry point with the calendar shift.
The competition also carries community value. MLS clubs do not exist only inside league rivalries. In the Open Cup, they can face lower-division opponents with local identities, regional followings, and different financial realities. That cross-level structure is rare in North American major professional sports, and it helps explain why the tournament remains important to supporters who value the full American soccer pyramid.

The return of full MLS participation also connects with previous analysis of full MLS first-team entry, which framed the 2027 change as a restoration of a key link between divisions and cup history.
Open Cup Future For MLS Clubs Beyond 2027
The 2027 edition will be a test of whether structure can restore competitive clarity. Full MLS entry gives the tournament a stronger field. The 96-team bracket preserves access for lower-division and amateur clubs. The Round of 64 start gives MLS teams a fixed entry point. The expanded bench and development-player access give clubs ways to manage workload without stepping away from the competition.
The remaining question is how seriously each club treats the opportunity once matches begin. A route to the Concacaf Champions Cup and a $1 million purse should raise the competitive stakes, but squad rotation will remain part of the tournament. That is not automatically a weakness. Cup football has often been shaped by clubs balancing league priorities with knockout risk.
If MLS clubs use the competition only as a reserve exercise, the sporting impact will be limited. If they use it as a serious title route, a player-development platform, and a connection point with the wider pyramid, the 2027 reset can strengthen the competition’s place in American soccer. The format now gives the tournament the conditions to matter. The records written from 2027 onward will show how clubs respond.
