What Is Arbitrage Betting?
Arbitrage betting (or "arbing") exploits odds differences between sportsbooks to guarantee a profit regardless of outcome. An arb exists when the implied probabilities of all outcomes sum to less than 100%.
Formula: If (1/OddsA + 1/OddsB) < 1, an arbitrage opportunity exists. The margin below 100% is your guaranteed profit percentage.
