Rarely does professional sports contract analysis begin with a 14-year-old, yet Cavan Sullivan has already rewritten that narrative.
In May 2024, the Philadelphia Union signed the teenage attacking midfielder to the largest homegrown contract in Major League Soccer history, tying a record financial milestone to one of the sport’s most extraordinary youth prospects.
Sullivan’s journey reads like a soccer prodigy story, he was born and raised in Philadelphia, joined the Union Academy at age 10 and progressed rapidly, from U15 to U17 to MLS NEXT Pro, where he registered game-winning assists in his first, early professional outings.
By July 2024, at 14 years and 293 days old, he became the youngest player to appear in an MLS match, eclipsing a two-decade old record and embedding his name in history.
The contract itself is historic, not just for the age at which it was signed, but for the strategic economic architecture that positions Sullivan as both a homegrown cornerstone and a future European asset, with a built-in pathway to Manchester City once he turns 18.
Contract Details
- Contract Type: Homegrown Player Contract (MLS)
- Length: 5 years (2024–2028)
- Guaranteed Compensation: ~$364,000 (per MLSPA 2024 salary guide)
- Base Salary (2025 Estimated): ~$200,000
- Signing Date: May 9, 2024
- Transfer Clause: Pre-arranged move to Manchester City upon turning 18
- Record Status: Largest homegrown contract in MLS history
Unlike typical MLS entry deals, which are capped by league minimums and strict homegrown salary guidelines, Sullivan’s contract represents a strategic investment in future value.
One designed not purely for on-field production in the short term, but for European transfer economics and long-term brand leverage.
MLSPA salary data shows his guaranteed compensation at ~$364,000 per year, making him one of the highest-paid homegrown players in the league relative to age and experience.
Salary Progression & Earnings Architecture
MLS homegrown contracts are structured differently than typical youth club deals:
- 2024 (Signing Year): Signing completed mid-season
- 2025 Estimated Base: ~$200,000 (pro-rated as applicable)
- 2026–2028: Rising guaranteed compensation around ~$364,000 annually (per MLSPA estimates)
Given Sullivan’s age and the league’s collective bargaining structure, his base salary revolves around guaranteed compensation rather than high AAVs seen in veteran and free agency signings.
The real value comes not just in wages but in future transfer economics tied to his pre-negotiated move to Manchester City at age 18, which could deliver the Union up to $5 million in transfer fees.
Player Profile & Cultural Capital
Sullivan isn’t simply a teenager signing a contract, he’s also the “next phenomenon” in the soccer world.
At just 14, he’s already a generational talent, with a resume that includes:
- Concacaf U-15 Golden Ball recipient for highest tournament performance
- Youth international standout with U.S. youth national teams
- MLS NEXT Pro playmaker with game-winning assists
- Breaking one of U.S. sport’s longest-standing professional debut records
He also comes from a family steeped in soccer culture, with his older brother, Quinn Sullivan, being a first-team player for the Union, anchoring his potential for continuity and engagement in Philadelphia.
That kind of cultural capital isn’t quantifiable like salary, but it drives market value, youth marketability, merchandise sales, global scout attention, and future transfer negotiation leverage.
Residency & Tax Strategy
Domestic soccer compensation flows through MLS’s unique commercial and tax structures.
For young players like Sullivan, residency and tax strategy become surprisingly meaningful:
- Home State: Pennsylvania (state income tax applies)
- Team Base: Philadelphia (taxable income)
- Away Jock Tax: Single-game earnings taxed across U.S. states where matches are played
MLS players are subject to proration of salary and bonuses based on match location (“jock tax”), meaning even in a first home base, multi-state tax liabilities apply.
Pennsylvania’s top marginal rate sits above neighboring no-tax states, which technically increases year-by-year tax drag compared with playing in a no-income-tax domicile.
However, Sullivan is so early in career earnings that tax planning and timing of guaranteed compensation (via MLSPA definitions and transfer fee components) will matter more once a European transfer arrives.
As he matures, residency choices, including potential offseason domicile outside high-tax states, can optimize net take-home and financial flexibility prior to a move to Europe.
Taxes, Fees & Expenses
Professional soccer income even at a young age doesn’t land untouched:
- Federal Income Tax: ~24–37% bracket depending on total income and deductions
- State Income Tax: Pennsylvania variable on guaranteed earnings
- Agent & Representation Fee: ~3–5% standard for elite youth negotiations
- Union Dues & League Fees: MLSPA dues, pension/benefit withholdings
- Professional Costs: Training, travel, performance staff, lifestyle allocations
While Sullivan’s guaranteed compensation appears modest compared to veteran MLS stars, the tax burden on that income, particularly in a high-tax state, means actual net income can vary materially based on residency planning and future transfer payouts.
Estimated Net Contract Value
Taking base salaries, guaranteed compensation, tax drag, and professional fees into account:
Estimated Net (2024–2028):
~$1.2M – $1.5M
Future Transfer Earnings: Up to ~$5M payable from Manchester City at age 18 (separate from MLS)
This mix highlights a crucial reality, MLS homegrown contracts are foundational, while true financial leverage comes from European transfer economics.
A model increasingly shaping global soccer income flows and where athletes choose to play.
Financial Outcome
- For Cavan: Even at an age when most athletes are in high school, Sullivan’s guaranteed earnings output and projected European transfer payout, gives him a financial runway few athletes see.
- For the Union: Philadelphia secured a generational talent before European competition could extract him for free, embedding both on and off-field potential for transfer economics into strategy.
- For MLS: Sullivan’s contract signals a shift, youth development is no longer nominal. It’s economic infrastructure, where homegrown pathways funnel into international moves and revenue streams.
His contract also reframes the MLS developmental model: the path is now quantified not just in minutes and milestones, but dollars and strategic monetization.
Cavan Sullivan’s homegrown deal is less about traditional salary scale and more about financial engineering for long-term value.
It marries guaranteed compensation with future transfer economics, tax strategy, and cultural capital, a blueprint for how elite global soccer prospects can be developed and monetized within the MLS ecosystem.
In an era when youth talent is worth millions before age 18, Sullivan’s contract is a financial roadmap for clubs and players alike, balancing early security, professional growth, and future earnings power.
