Void, settled, or still open

Most of the time the distinction does not come up: the event finishes, the bet is settled, the balance changes. It comes up when something irregular happens — an abandonment, a postponement, a withdrawal, a correction to the official result — and then it decides everything.

The rules governing it are in the bookmaker's own terms, they vary by book and by sport, and they are the part of a betting account nobody reads until it matters.

The three states

Open

The outcome is not yet determined by the rule, whatever the scoreboard says. A pre-match bet is open until the match completes under the book's definition of completion; our basketball guide describes pre-match bets as priced before the start and settled on the final result, which is the ordinary case.

Settled

The rule has been applied and the bet has won, lost or been partially resolved. Settlement can precede the end of the event, as with an early-payout rule, and it can follow it by a long time where an official result is pending.

Void

The bet is treated as never having been placed, and the stake is returned. Not a loss and not a win. The important part is which circumstances trigger it, because that list is the book's choice.

What typically voids a bet

The common triggers, with the caveat that each book defines its own:

• the event is abandoned before the book's threshold for a completed event;
• the event is postponed beyond a stated window;
• a participant withdraws before taking part, in markets where that participant was the subject of the bet;
• the venue, surface, format or distance changes materially;
• the market was offered at an obviously wrong price, or after the outcome was already known;
• a relevant official result is amended.

Thresholds are where the real variation sits. Whether a match abandoned late counts as completed, and whether a bet on an event within it stands once that event has already happened, differ between books in ways that are entirely defensible and entirely inconsistent.

The multiple-bet consequence

Here is the practical reason to care. In an accumulator, a void leg is normally removed and the accumulator recalculated on the remaining legs, at lower total odds. Nothing has gone wrong, but the bet you are holding is not the bet you placed, and its return is smaller than the slip said.

Two corollaries. A void in a long accumulator can reduce the return substantially while the bet still wins. And a leg you expected to be void, because a participant did not take part, may instead be settled as a loser if the book's rule treats non-participation differently in that market. Both outcomes are in the rule, and only in the rule.

Early settlement is not the same as a void

Early payout rules settle a bet as a win before the event ends. Our German basketball guide records the clearest form of it:

bet365 pays out early when a team leads by 20 points.

Once that rule has fired the bet is settled and the subsequent course of the game is irrelevant — a comeback does not undo it. That is a genuine advantage of one book's rules over another's at the same price, and it is the reason comparing odds alone understates the difference between books. The same logic runs through why two books price differently.

Cash-out, which is a third thing

Cashing out is neither settlement nor a void: it is selling the bet back at a price the book sets, and that price includes a margin. A cash-out offer is not a valuation of your position, it is an offer. It also closes the bet permanently, so it cannot later be voided or early-settled in your favour.

What to read, once

Per book, find the settlement section and note four things: the definition of a completed event for your sports, the treatment of postponements and the window, the non-participation rule, and how voids are handled inside multiples. That is a single sitting, it does not change often, and it is the difference between a surprising settlement and an expected one.

If a settlement looks wrong, the rule is the argument. Ask which clause the settlement was made under and compare it with the market's own terms as they stood when the bet was placed — the same approach that works on the casino side in refused payouts.
