Arbitrage betting (surebets) means covering all outcomes of an event at different bookmakers so that any result produces guaranteed profit.
How Arbitrage Works
Simple example: tennis, two outcomes. Bookmaker A offers 2.10 on player 1. Bookmaker B offers 2.05 on player 2. Sum of implied probabilities: 1/2.10 + 1/2.05 = 0.964. Less than 1 — arbitrage exists!
📐 Arbitrage Profit Formula
Profit = (1 - 1/K1 - 1/K2) × 100%
