Cash out is not guaranteed
Betfair's cash-out documentation provides one current sportsbook example in which an offer may change, be suspended, fail during acceptance, or be unavailable. The accepted cash-out receipt matters; a displayed amount is not yet a completed transaction.
Build the hold table first
Suppose an illustrative GBP 20 football bet was accepted at decimal odds 3.00. Its hold-to-settlement states are:
| Final settlement | Cash received | Net result relative to original stake |
|---|---|---|
| Win | GBP 60 | +GBP 40 |
| Loss | GBP 0 | -GBP 20 |
| Full void | GBP 20 | GBP 0 |
Now suppose a cash-out quote of GBP 26 appears. Accepting it would lock a net result of GBP 26 - GBP 20 = +GBP 6 if the transaction completes. It replaces exposure to the table; it does not prove that GBP 26 is a fair value.
Compare values with declared probabilities
If an illustrative model assigns probability 0.45 to the win and 0.55 to the loss, with no void state:
Expected hold cash = (0.45 * GBP 60) + (0.55 * GBP 0) = GBP 27
Expected hold net result = GBP 27 - GBP 20 = +GBP 7
Under those invented inputs, the GBP 26 offer is GBP 1 below expected hold cash. A small probability change reverses the comparison, and expected value is not a guaranteed result. The calculation follows the complete-outcome method in OpenStax's expected-value chapter.
Include states simple examples omit
Add any state that can alter the contract: a push, void, dead heat, player non-participation, abandoned match, partial cash out, settled leg, promotion adjustment, tax, fee, or correction. Betfair's sportsbook rules illustrate that product and market rules can affect settlement and feature treatment.
Decision record
| Field | Required value |
|---|---|
| Original ticket | Stake, accepted price, selection and rule |
| Live state | Score, clock, player count and source timestamp |
| Quote | Amount, quote time and portion of position |
| Forecast | Probabilities for every remaining payoff state |
| Acceptance | Completed amount and receipt time, or failed attempt |
| Alternative | Hold, partial action, separate hedge, or no action |
The Gambling Commission's in-play standard warns that event information can be delayed. A model state and cash-out quote should be joined by timestamp rather than assumed to describe the same instant.
Reasons that are not valuation evidence
Wanting to protect a winning screen, recover an earlier loss, avoid regret, or reach a round cash amount does not estimate the remaining payoff probabilities. Cash out can reduce exposure, but exposure should already fit an affordable limit without depending on the feature.
