The United States Soccer Pyramid: Tiers, Promotion, and the MLS Question
The US soccer pyramid has 5+ tiers but no promotion or relegation. We explain MLS, USL Championship, USL League One, NWSL, the new MLS Next Pro, and what makes the US system unique.
The United States soccer pyramid has 5+ professional and semi-professional tiers, but unlike European football, there is no promotion or relegation between tiers. MLS sits at the top as a closed league with single-entity ownership; USL Championship and MLS Next Pro form the second tier; USL League One and USL Super League the third; USL League Two and amateur leagues the rest. The structure is widely debated — pro/rel is the perpetual hot topic in US soccer.
The current tier structure
The 2025-26 US soccer pyramid (men's):
- Tier 1 — MLS (Major League Soccer). 30 teams across the US and Canada. Single-entity ownership; no relegation. Salary cap (with designated player exceptions). Founded 1996.
- Tier 2a — USL Championship. 24 teams. Independent ownership; no promotion to MLS. Founded as USL Pro in 2011, rebranded 2018.
- Tier 2b — MLS Next Pro. 28 teams (most are MLS reserve teams). Founded 2022. Effectively MLS reserve league.
- Tier 3 — USL League One. 12+ teams. Founded 2019.
- Tier 3 — USL Super League (women's). Launched 2024-25 season as the parallel women's pro tier alongside NWSL.
- Tier 4 — USL League Two. ~120 teams. Pre-professional / college-development tier.
- Tier 5 — National Independent Soccer Association (NISA). ~6-8 teams. Independent professional league.
No promotion or relegation between any tier. A USL Championship-winning club cannot be promoted to MLS — it must apply for an MLS expansion slot and pay a fee (most recently $500m for San Diego in 2023).
Why no promotion / relegation
Three structural reasons:
- MLS single-entity model. MLS owners collectively own player contracts, not the clubs individually. This makes it legally impossible for an outside club to be "promoted" without being absorbed into the entity.
- Investor protection. MLS expansion fees ($500m+ for recent slots) protect existing owners from devaluation. Promotion would let outside clubs compete without paying the fee.
- Sports business culture. All major US sports leagues (NFL, NBA, MLB, NHL) are closed leagues. The pro/rel system is foreign to American sports investment culture.
Women's soccer pyramid
The women's structure is similar:
- Tier 1 — NWSL (National Women's Soccer League). 14 teams. Closed league. Founded 2012; the most successful women's pro league globally.
- Tier 2 — USL Super League. Launched 2024-25 as a parallel women's pro tier.
- Tier 2 — WPSL Pro (proposed). A planned independent second tier.
- Tier 3 — Women's Premier Soccer League (WPSL). Pre-professional / development tier with ~150 teams.
How it compares to England
Three structural differences from English football:
- Connected vs disconnected pyramid. England has uninterrupted pro/rel from Premier League through to amateur leagues. US has 5+ tiers but no movement between them.
- Number of professional teams. England has 92 fully-professional clubs (Premier League + EFL). The US has ~70 across MLS + USL Championship + USL League One.
- Ownership structure. English clubs are individually owned. MLS is single-entity. This affects everything from player movement to transfer market dynamics.
The pro/rel debate
The US soccer community has been debating promotion/relegation for two decades. Three positions:
- Pro/rel advocates. Argue that pro/rel would create competitive intensity, reward investment in lower divisions, and align US soccer with the global game. The "Free MLS" movement has been vocal since 2010s.
- MLS owners + status quo. Argue that closed leagues attract investment, prevent financial collapse of struggling clubs, and reflect US sports culture. MLS commissioner Don Garber has consistently rejected pro/rel proposals.
- Hybrid proposals. Some argue for limited pro/rel below MLS (USL Championship → USL League One → USL League Two), while keeping MLS closed. Has been discussed but not implemented.
How the World Cup 2026 might change things
The 2026 World Cup, hosted across the US, Canada, and Mexico, has put US soccer infrastructure under unprecedented attention. Three potential outcomes:
- Stadium investment legacy. WC2026 stadiums will support MLS expansion to 32+ teams.
- Increased grassroots investment. US Soccer is funding youth academies and pre-professional pathways more aggressively.
- Possibly opening pro/rel discussion. International scrutiny could re-open the closed-league debate. Most observers think it remains unlikely in the next 10 years.
Frequently asked questions
- How does the US soccer pyramid work?
- The US has 5+ tiers but no promotion or relegation between them. MLS (30 teams) sits at the top as a closed single-entity league. USL Championship (24 teams) is the second tier. MLS Next Pro (28 teams, mostly reserves) and USL League One (12+ teams) are below. USL League Two and NISA are tier-3 / pre-professional. Movement between tiers requires expansion-fee payment, not on-pitch promotion.
- Why is there no promotion or relegation in US soccer?
- MLS uses a single-entity ownership model where MLS owners collectively own player contracts, making outside-club promotion legally impossible without absorption. MLS expansion fees ($500m+ for recent slots) protect existing owners from devaluation. The closed-league structure also matches the cultural pattern of all major US sports (NFL, NBA, MLB, NHL).
- How many tiers are in US soccer?
- 5+ tiers. Tier 1: MLS. Tier 2: USL Championship + MLS Next Pro (parallel second tiers). Tier 3: USL League One + USL Super League (women's, launched 2024). Tier 4: USL League Two. Tier 5: NISA + amateur regional leagues. Total ~70 fully-professional clubs across all tiers in 2025-26.
- Is the US the only major country without pro/rel?
- Among major footballing nations, the US is unusual. Australia's A-League is similarly closed. China's top tier is technically open but often functions as closed in practice. Most major football countries (England, Spain, Germany, Italy, France, Brazil, Argentina, Portugal, Netherlands, etc.) have full pro/rel from top to bottom of the pyramid.
