Start with the settlement question
The market name is only a label. A complete definition states the event, time period, data authority, treatment of extra time, player participation, abandoned matches, corrections, pushes, dead heats, and voids. Betfair's current football rules provide one operator example: default match markets use 90 minutes plus stoppage time unless the market says otherwise, while individual products add their own settlement conditions.
Football law and betting settlement are separate layers. The IFAB Laws of the Game define events on the field; the operator decides how a named betting product uses those events. A referee can award a corner or caution under football law, but a market may specify a different data feed or count only an event that reaches a stated settlement stage.
Five settlement shapes
- Binary: one selection wins or loses, such as BTTS Yes under a defined period.
- Three-way: home, draw, or away are separate selections, including a European handicap after score adjustment.
- Refund-capable: a draw or exact line can return the stake, as in draw no bet or an Asian whole line.
- Split-line: one stake is divided equally across adjacent lines, creating half-win or half-loss outcomes.
- Multi-event: every named component must settle as required, as in scorecast or result-and-BTTS.
The payoff must follow the settlement shape. OpenStax's expected-value treatment supports listing mutually exclusive outcomes, assigning each a probability, and weighting its net payoff. A three-state or split-line bet should not be forced into a win-or-lose formula.
Worked settlement record
Consider an illustrative GBP 20 stake on Over 2.0 goals at decimal odds 1.85:
| Regulation-time goals | Settlement | Gross return | Net result |
|---|---|---|---|
| 0 or 1 | Loss | GBP 0 | -GBP 20 |
| 2 | Push | GBP 20 | GBP 0 |
| 3 or more | Win | GBP 37 | GBP 17 |
Gross return on a win = 20 * 1.85 = 37
Net profit on a win = 37 - 20 = 17
The same fixture could settle differently at Over 2.5 because two goals would lose rather than push. That difference belongs in the decision record before a probability or price is compared.
Minimum pre-bet record
- Operator and exact market label.
- Selection, line, and accepted price.
- Regulation time, extra time, or competition scope.
- Official result or statistics source named by the rules.
- Push, split, void, dead-heat, and non-runner states.
- Requested stake, accepted stake, and maximum possible loss.
- Forecast probability and information cutoff, when analysis is being evaluated; settlement fields can be checked against current operator football rules.
Do not multiply component probabilities merely because a product contains two events. OpenStax distinguishes independent events from dependent events; football events within the same match can share score state, team strength, tactics, and playing time.
Assumptions and limitations
This pillar explains product mechanics with illustrative prices and scores. It does not list every operator market, identify a best market, or establish positive expected value. Rules can differ by operator, jurisdiction, competition, data provider, and date; retain the wording that applied when a bet was accepted.
