What ante-post means
Ante-post describes a market opened well ahead of an event or before the final participants are confirmed. Prices can change as the event approaches, and the selection may not take part.
The key practical point is the market's non-runner or withdrawal rule. Check the market's non-runner or withdrawal terms before choosing an ante-post selection.
Terms to compare
Check when the market moves to day-of-event terms, what happens to a non-runner, how a withdrawal is handled and whether a specific event cancellation voids all selections. The operator's market rules control settlement.
For racing, compare ante-post conditions with the race-day market. Golf outright markets can also have withdrawal or tie terms that need checking.
Calculate without confusing the rules
The odds converter and return calculator can show price arithmetic for a selected stake. They do not model whether a market is ante-post or how a non-runner is settled.
Use the settlement-rules guide for general terms and the horse-racing hub for current race routes.
