How it works
- Lay stake = back stake × back odds ÷ (lay odds − commission rate) for a cash bet.
- Liability = lay stake × (lay odds − 1) — what the exchange holds.
- The result is the same whichever way the race goes.
Betting involves risk. Bookmakers can restrict or close accounts and void bets, automation can fail, prices move, and a positive expected value (+EV) bet can still lose. Promotions carry each bookmaker's own terms. There is no guarantee of profit. See responsible gambling for limits and support.
