In a landmark decision, all 27 United States-based MLS teams will participate in the Lamar Hunt U.S. Open Cup in 2027. This marks the first time since 2024 that every MLS club will compete in the tournament, which has been a staple of American soccer since its inception in 1913.

The U.S. Open Cup is recognized as the oldest running soccer competition in the country and ranks as the third-longest continuously running cup in the world. The absence of MLS teams in the past few seasons was due to match congestion from the Concacaf Champions Cup, but with adjustments made to the tournament's schedule, including shifting later rounds to September, MLS teams will now be back in the mix.

Key highlights include:

• $1 million prize for the tournament winner.
• A coveted spot in the Concacaf Champions Cup.
• The last non-MLS team to win was the Rochester Rhinos in 2000.

Dan Helfrich, U.S. Soccer Chief Operating Officer, emphasized the importance of the tournament, stating, "The Lamar Hunt U.S. Open Cup is one of the most powerful platforms we have to showcase what makes American soccer special."

The upcoming format will feature a 96-team field, with first-round matchups announced in early 2027. Notably, the gameday rosters will expand from 18 to 20 players. The first round will involve 32 teams from MLS Next Pro, amateur clubs, and teams from USL League One and the USL Championship. Additionally, five seeded teams from the USL will enter in the round of 64.

This renewed participation highlights a shared commitment to strengthen the future of soccer in the United States.
