Arbitrage Betting

Arbitrage betting, also known as arbing, is a method used by bettors in order to secure a guaranteed profit from a bet. The practice involves placing a back bet and a lay bet on the same outcome of an event after performing a calculation designed to guarantee profit regardless of the result. Crucially, arbitrate betting requires the odds for the back bet to be higher than the lay. Without higher back odds, backing and laying the same outcome will always result in a loss.

Arbitrage betting is often confused with dutching, though the two practices have key differences.

Controversy and Account Losses
Arbitrage betting is not illegal, but bookmakers will stake restrict or suspend the accounts of users found to be arbing.

Terminology

 * An event outcome that features higher back bet odds than lay odds will often be referred to as an "arb".
