In its current format, the U.S. Open Cup is contested by approximately 100 clubs from the
professional leagues sanctioned by the USSF, MLS, the
USL Championship and
League One divisions, the
National Independent Soccer Association (NISA), and
MLS Next Pro – as well as amateur clubs in the earlier rounds of the tournament that qualify through their respective leagues. The overall champion is awarded $300,000 in
prize money and a berth in the
CONCACAF Champions Cup, while the runner-up receives $100,000, and the furthest-advancing team from each lower-division league receives $25,000.
MLS era MLS teams have dominated the competition since the league began play in 1996. No lower division team has won the Open Cup since the
Rochester Rhinos in 1999, and the most recent lower division team to reach the final was
Sacramento Republic FC in
2022. The most recent champions of the competition,
Nashville SC, won their first title after defeating
Austin FC in the
2025 final. From 1996 to 2023, MLS teams had participated in every Open Cup competition. The
2022 U.S. Open Cup marked the return of the competition after the 2020 and 2021 tournaments were canceled due to the
COVID-19 pandemic, ending 106 years of consecutive play.
Pre-2023 formats Through the 2011 edition, eight teams from each level of the
American Soccer Pyramid took part in the competition proper, with each league narrowing its delegation separately in the spring before the competition officially began in the summer. In some cases, additional teams played in qualifying rounds to gain entry. One example was found with MLS clubs, as only the top six from the previous regular season received automatic bids, while the bottom U.S.-based MLS teams faced each other to qualify for the remaining two MLS slots. Beginning in 2012, the competition was expanded from its previous 40 teams to 64, with the qualifying process radically changed. The
National Premier Soccer League received six places, plus the possibility of a seventh in a playoff against a team from the amateur
US Club Soccer setup. Nine clubs from the USASA earned places, as did 16
USL Premier Development League teams. Each of these organizations has its own qualifying process to determine its entrants. These 32 teams competed in the first round of the Cup, with the winners meeting all 16 USL Pro and NASL teams in the second round. The 16 U.S.-based MLS teams entered in the third round. In 2013 the competition was expanded to 68 teams. All U.S.-based Division I, II and III teams participated in the tournament proper: 16 from Major League Soccer, six from the North American Soccer League and 12 from USL PRO. The remaining 34 spots in the tournament field were filled by amateur teams from the Adult Council category–16 from the Premier Development League, eight from U.S. Adult Soccer Association regional qualifying, eight from the National Premier Soccer League, one from US Club Soccer and one from the
United States Specialty Sports Association. The process for determining the site for the Open Cup tournament semifinals and final was changed in 2013. In past years, the sites for the final three matches of the tournament had been determined through a sealed-bid process, but in 2013 the hosts of those games were determined by a coin flip. Home teams throughout the entire tournament were determined by random selection. Starting in 2016, lower-division professional clubs owned by higher-division professional clubs are no longer eligible to participate in the U.S. Open Cup. This removed the MLS reserve clubs in USL from the 2016 competition, after issues of clubs holding back players from their USL sides in 2015 in order to keep them eligible to play for the parent MLS club. Players are
only allowed to play for one club in any US Open Cup season. Amateur clubs remain eligible to enter even if they are owned by professional clubs. Initially, "hybrid affiliate" clubs—i.e., lower-division professional clubs that are staffed but not owned by higher-division clubs—also remained eligible, but those clubs were also banned effective with the 2016 competition. This last change was proposed by the
Houston Dynamo, which were the senior club to
Rio Grande Valley FC Toros in the first such arrangement in the U.S. game; that arrangement ended after the 2021 season, and those two teams would be drawn against each other in 2022.
Post-2023 changes On December 15, 2023, MLS announced that affiliated reserve teams from MLS Next Pro would be sent in place of MLS teams for the 2024 edition. U.S. Soccer subsequently denied the request, ruling that MLS teams must compete in the 2024 edition of the U.S. Open Cup. For the 2025 US Open Cup, US Soccer announced that 16 MLS teams would appear in the fourth round. For the first time in the modern era, the US Open Cup defending champions will not defend their crown with LAFC participating in the
CONCACAF Champions Cup. Likewise, half of the MLS teams would be given priority hosting and half would be designated as away teams when they begin their US Open Cup appearance in the third round. The selection of MLS teams for the U.S. Open Cup was folded into a wider scheme to ensure that MLS clubs were represented in all the secondary competitions in which the league's teams compete, while none were overloaded with fixture congestion - The
CONCACAF Champions Cup, the zonal
Leagues Cup, the
Canadian Championship and the
U.S. Open Cup. As part of that arrangement, the Division III
MLS Next Pro teams of most of the absent MLS teams based in the United States took part instead, ensuring their representation. The 16 MLS first teams represented in the
2025 U.S. Open Cup were chosen based on the following criteria: • Teams participating in Concacaf Champions Cup are excluded from the Open Cup, including the reigning champion
Los Angeles Football Club. • Teams not participating in the 2025 Leagues Cup qualify for the Open Cup, ranked based on 2024 Supporters Shield Standings • The next best teams in the Supporters’ Shield Standings that are not in the CONCACAF Champions Cup will enter the Open Cup. • Expansion team
San Diego FC did not enter the 2025 U.S. Open Cup. ==History==
