What is Arbitrage Betting?
Arbitrage (or "arbing") exploits odds differences between bookmakers to guarantee profit regardless of outcome. When the combined implied probability of all outcomes is less than 100%, an arbitrage opportunity exists.
How It Works
If Bookmaker A offers 2.10 on Team X and Bookmaker B offers 2.05 on Team Y, the combined implied probability is: (1/2.10) + (1/2.05) = 47.6% + 48.8% = 96.4%. Since this is under 100%, you can stake proportionally on each outcome for guaranteed profit.
Reality Check
True arbitrage opportunities are rare and short-lived. Bookmakers actively monitor for arbers and may limit or close accounts. The margins are typically 1-3%, meaning you need significant capital and many bets to earn meaningful profit.
