Define the field, not only the selection
The DraftKings market rules and FanDuel rules published by the Massachusetts regulator illustrate why the opening field and settlement contract must be retained. A league-winner probability is one part of a complete mutually exclusive field. A top-scorer market may allow ties or dead-heat reductions. Promotion, relegation and qualification depend on official competition structure and operator wording.
| Futures family | Field record | Material settlement question |
|---|---|---|
| League or tournament winner | Every offered and unoffered participant | What happens if format or field changes? |
| Top scorer | Every eligible player and no-participation states | Dead heat, own goals, qualifying rounds, team transfer |
| Promotion or relegation | Every club and administrative state | Play-offs, deductions, expulsion, incomplete season |
| Group or stage qualification | Every path through the competition | Tie-breakers, seeding, advancement definition |
The FIFA legal-documents portal is one route to current governing documents; each competition's own regulations remain controlling for its format.
Preserve the accepted futures rule
DraftKings' market and soccer rules provide a current operator example, while the FanDuel rules published by the Massachusetts regulator show a state-specific example of futures, interruption and official-body treatment. Rules can differ by operator and state.
Record:
- competition edition and scheduled completion date;
- field, eligibility and "all-in" or non-runner wording;
- dead-heat and tie-break treatment;
- shortened, postponed or materially changed format rules;
- accepted price, stake, maximum payout and timestamp;
- expected settlement date and funds locked until then.
Worked time and return record
Suppose two hypothetical independent league-winner legs are accepted at 3.00 and 4.50 for a $10 futures parlay.
Combined price = 3.00 * 4.50 = 13.50
Gross return if both win = 10 * 13.50 = $135.00
Net profit = 135 - 10 = $125.00
If illustrative win probabilities are 0.34 and 0.24:
Joint probability under independence = 0.34 * 0.24 = 0.0816, or 8.16%
Raw break-even probability = 1 / 13.50 = 0.0741, or 7.41%
OpenStax's independence condition must be justified. Shared owners, transfers, continental schedules, players, model priors and economic shocks can connect competitions.
Path probability
A team reaching a later stage changes its remaining route. Update through explicit conditional paths rather than treating an opening price as a fixed forecast. Preserve every update separately; do not overwrite the probability attached to the accepted ticket.
Capital lock-up and exposure
The possible return is not available bankroll. Track the cash stake as open exposure until final settlement, and aggregate multiple futures that rely on the same club or player. Compare a futures position with shorter-horizon alternatives using the same cash and time window.
Expected value uses state probabilities and net payoffs under OpenStax's framework; it does not compensate automatically for months of uncertainty or inaccessible funds.
Review checklist
- Confirm the official competition edition and complete field.
- Record format, tie-breaker, dead-heat and participation rules.
- Build a path model with uncertainty, not one narrative scenario.
- Map shared teams, players and competition causes across legs.
- Save the accepted price, limit, stake and rule version.
- Keep open futures separate from settled bankroll and return metrics.
- Re-queue the analysis when the field, format or evidence changes.

Assumptions and limitations
The prices, probabilities and competitions in the worked example are hypothetical. Futures availability, maximum payouts, tax treatment, interruptions, dead heats and settlement can vary by state, operator and event. This page provides no current winner or scorer picks.
