Bet Settlement
The process by which a bookmaker or exchange officially determines a bet's result and credits winnings or collects the stake.
Definition
Settlement (or grading) is the step after an event where the operator confirms the official result, applies its market rules, and pays winners or keeps losing stakes. Rules govern edge cases: which result source is official, how dead heats are split, when a bet is voided, and how palpable (obvious) pricing errors are handled. Settlement can be delayed until a result is official, and a winning decimal bet returns stake plus profit, for example $100 at 2.00 settles as $200 returned ($100 profit).
Worked example
Your $100 bet at decimal 2.00 wins. On settlement the book credits $200 total: your $100 stake back plus $100 profit. If the event had been abandoned under the book's rules, it would instead settle as a void with the $100 refunded.
Why it matters
Understanding settlement rules protects beginners from disputes over voids and dead heats, and professionals read the fine print because obscure grading rules can quietly change a bet's real value.
