Standard Parimutuel Wagering Rules

Welcome to the comprehensive guide to pari-mutuel wagering rules for various jurisdictions around the world. Pari-mutuel wagering, a system where all bets of a particular type are placed together in a pool, and the payoff odds are calculated by sharing the pool among all winning bets. Pari-mutuel betting, otherwise known as “pool betting” is a popular method of betting on horse racing, greyhound racing, and other sporting events.

Many jurisdictions use the Association of Racing Commissioners International (ARCI) model rules as a starting point. This document outlines standardized regulations intended to ensure consistency and fairness across different regulators. It has been added below in addition to all of the various jurisdictions.

This guide provides details of the laws and rules governing pari-mutuel wagering to ensure fair play and integrity in betting activities. Each jurisdiction has specific variations and additional regulations, so it is essential to consult the detailed rules applicable to the track or event you are wagering on. In most cases the presiding jurisdiction is the location of the event, however for some international events (“B-Pools”) and for sporting events outside of horse and greyhound racing the presiding jurisdiction will be the location of the pool host. For US based operators this is usually either Oregon or North Dakota. Please find and view the relevant link below for full details on the pari-mutuel wagering rules for each jurisdiction.
