What is Arbitrage?
Backing every outcome of an event across different bookmakers at prices that guarantee profit.
Definition
Arbitrage ('arbing') exists when bookmakers disagree enough on a market that the sum of inverse odds is below 1.0. Backing all outcomes proportionally locks in a small risk-free margin (typically 1-4%). Tools like RebelBetting and BetBurger scan thousands of markets per minute. The catch: soft books detect arbing and limit accounts within 5-50 bets, so arbing has a finite lifespan per book. Sharp books (Pinnacle, BetInAsia) tolerate arbers because they shape the lines.
Example
Real Madrid 2.20 at Bet365, Draw 3.80 at Stake, Barca 3.50 at William Hill. Sum 1/2.20 + 1/3.80 + 1/3.50 = 0.97 → 3% arb.
