Full MLS Participation Changes the U.S. Open Cup Commercial Brief

Full participation restores the national platform

U.S. Soccer confirmed on September 2 that all 27 U.S.-based Major League Soccer clubs will participate in the 2027 Lamar Hunt U.S. Open Cup. It will be the first edition with full MLS participation since 2023.

The decision gives the competition greater sporting credibility, a more complete national footprint, and a clearer proposition for media and commercial partners. It also creates a useful test for how American soccer packages a property that operates simultaneously as a national championship and a collection of local events.

The 2027 competition will include 96 teams from the professional and amateur game. It will begin in April and conclude on December 15, with the later rounds scheduled after Labor Day to accommodate changes in the U.S. professional calendar.

The tournament will offer a $1 million purse and entry into the Concacaf Champions Cup. Its existing partners include Marriott, Michelob Ultra, New York Life, and Nike.

Those facts establish the platform. They do not automatically create commercial value. For U.S. Soccer, participating leagues, clubs, broadcasters, sponsors, and prospective partners, the larger task is to translate the competition’s unusual structure into a coherent business proposition.

The Open Cup combines national scale with local consequence

Most national sports properties begin with a centralized audience and distribute standardized inventory across participating markets. The Open Cup works differently.

Its national significance comes from bringing separate levels of American soccer into one competition. Its individual matches remain rooted in specific clubs, venues, cities, and supporter communities.

The first round will pair professional and amateur clubs. Geography will influence early pairings, while lower-division teams advancing from the Round of 64 will receive hosting priority in the Round of 32.

This creates a national championship made from major professional clubs, lower-division markets, amateur organizations, regional matchups, community venues, local supporter stories, and a pathway into continental competition.

A sponsor can participate nationally while still having a reason to operate differently in Sacramento, Charleston, Detroit, Miami, San Diego, or another participating market. That combination is difficult to reproduce through a standard league sponsorship.

Full MLS participation restores an important part of the proposition

Only 16 U.S.-based MLS clubs participated in the 2026 Open Cup. The league had reduced its involvement after 2023 while managing schedule congestion and its other competitions.

According to ESPN’s September 2 report, MLS has now removed the restriction that generally limited clubs to two non-league competitions. Qualified teams will be able to participate in the Open Cup, Leagues Cup, and Concacaf Champions Cup.

Roster flexibility can help clubs manage multiple competitions, but it introduces a commercial variable. The participating club may be consistent; the lineup, audience interest, venue, and level of promotion may not be.

Partners should avoid treating every MLS appearance as an equivalent media or hospitality asset.

The tournament calendar creates several commercial windows

The 2027 competition is scheduled across most of the year, beginning with first-round matches in April, followed by the Round of 64 in July, the Round of 32 in September, quarterfinals in November, and the semifinals and final in December. Dates remain subject to change.

A long calendar can make the property harder to communicate as one continuous campaign. It can also create distinct programming periods.

The early rounds can emphasize access, community participation, amateur ambition, and regional identity. MLS entry in July provides a larger national moment. The fall knockout rounds can support more concentrated media, hospitality, and consumer activation. The December final becomes a separate closing event.

A single creative campaign running unchanged from April through December is unlikely to use the structure effectively. A stronger model would maintain one central brand role while changing the execution by stage.

Consistency should come from the commercial purpose, not from identical activation.

The amateur field gives the property a distinctive business asset

A record 155 amateur clubs entered qualifying for the 2027 competition, according to U.S. Soccer’s August 26 update. Sixteen clubs will advance through four qualifying rounds, while another 16 received direct places based on results in selected competitions.

This structure gives the Open Cup a quality that major professional leagues cannot offer alone: a legitimate connection between local participation and the national professional game.

For commercial partners, the opportunity should not be reduced to an underdog advertising theme. Amateur and lower-division clubs can provide entry into markets without an MLS club, community credibility, small-business participation, volunteer and employee programs, documentary content, regional promotions, and a visible connection between professional soccer and participation.

Delivery will vary considerably. Some clubs have established venues, ticketing operations, content teams, and commercial staff. Others operate with limited personnel and infrastructure.

A national partner therefore needs an activation system that local organizations can use without imposing unreasonable operating requirements. That may include modular creative assets, small-market production support, event templates, promotional grants, signage kits, digital tools, staff guidance, and clear rules for local participation.

The value of a distributed platform depends partly on whether its smallest operators can deliver it.

Geography is part of the product

Early-round pairings will be organized geographically. U.S. Soccer will also associate each first-round matchup with a team entering in the Round of 64. This reduces travel demands and increases the possibility of recognizable regional stories.

Commercially, it creates an operating map that can serve different objectives. A national consumer brand may want broad participation across the competition. A regional financial institution may prioritize clubs within its business footprint. A telecommunications provider may focus on selected venues. A business-to-business company may use matches in markets where it has customers, employees, or prospects.

Those layers require clear rights management. U.S. Soccer, leagues, clubs, venues, broadcasters, and existing partners may control different assets. Local sponsors can also hold category relationships that conflict with a national tournament partner.

A commercially effective structure needs to explain which rights travel across the competition, which remain local, and which require separate agreement.

The media plan must make the competition easier to follow

Every first-round match in the 2026 competition was streamed. CBS Sports served as the multimedia rights partner, with selected matches carried across Paramount+, CBS Sports Network, and CBS Sports Golazo Network. Other games were available through U.S. Soccer’s YouTube channel.

The 2027 media arrangement has not yet been confirmed publicly. Full MLS participation should strengthen the potential media proposition, but the number of teams and matches also creates a discovery problem.

Supporters need to know where each match is available, which games receive national distribution, how local matches can be found, when live draws take place, how the bracket is developing, and which clubs and markets have produced unexpected results.

The Open Cup should be treated as a content system, not only a collection of match feeds. The live draw can become programming. Amateur qualifying can introduce clubs before the tournament proper begins. Regional pairings can support local media. Short-form content can explain the stakes to audiences unfamiliar with the competition.

Sponsors can contribute to that system when their role improves access or understanding. Branded highlights, travel stories, club profiles, prediction formats, and local guides can be useful. Additional logo exposure without a clear function will contribute less.

Partners should solve operating problems

U.S. Soccer began increasing its investment in the competition in 2024, including travel reimbursement, promotion, and financial incentives. The purse reached a record $1 million in 2025 and remains at that level for 2027.

This investment recognizes a central reality: an open national competition creates costs and operating pressures that are not distributed evenly.

A travel brand could support the movement of teams and create supporter travel content. A financial company could help lower-division organizations manage payments or local business participation. A technology provider could improve scheduling, content distribution, registration, or venue operations. A retailer could connect amateur participation with product access.

The operating contribution gives the partnership a reason to exist. Marketing can then explain that role.

Hospitality will require market-specific standards

The return of every U.S.-based MLS club expands the number of markets where the competition can support client and partner experiences. The opportunity is not equivalent to a conventional season-ticket or premium-suite program.

Open Cup venues, match schedules, hospitality infrastructure, and customer demand can vary by round. An early matchup at a smaller venue creates a different experience from a semifinal hosted by an MLS club.

That variation can be an advantage when handled deliberately. A smaller setting may provide closer access, a stronger local story, and a less formal customer environment. A later-round MLS match may support larger guest programs and established premium inventory.

A national hospitality promise should not be made without understanding local delivery.

Measurement should reflect the tournament’s structure

The Open Cup cannot be evaluated responsibly through one total audience figure.

A national sponsor should distinguish among qualifying participation, first-round local engagement, MLS entry in the Round of 64, national media coverage, local streaming audiences, attendance, hospitality, content consumption, sponsor recognition, community participation, customer activity, and relationships retained after elimination.

The tournament also produces a changing set of active markets. A sponsor may lose local relevance when a participating club is eliminated, while another market gains value through an unexpected run.

Measurement and activation funding should be flexible enough to respond. Brands should set a national baseline, define priority markets, and reserve resources for clubs or stories that become commercially significant during the competition.

The knockout structure creates uncertainty. That uncertainty is part of the product.

The property needs a national core and local modules

The 2027 format gives the U.S. Open Cup a stronger foundation. All U.S.-based MLS clubs will participate. The amateur qualifying field has reached a record size. The competition connects several professional divisions with community-based soccer. Its calendar creates multiple activation periods. Its geographic structure provides local relevance within a national tournament.

The next commercial step is to package those elements without removing what makes the competition different.

Full MLS participation provides scale and recognition. The more valuable proposition is broader. The Open Cup can connect professional visibility, local identity, community participation, and national competition within one commercial platform.

Brands should not approach it as a smaller version of an MLS partnership. The competition requires a different strategy, one designed around movement between levels, markets, rounds, and audiences.

That complexity is not simply an obstacle to manage. Properly organized, it is the commercial asset.
