Welcome to Arb Spy

We are a FREE service that finds sports arbitrage opportunities (also known as "sure bets") and bonus arbitrage opportunities from more then 120 online bookmakers and exchanges.
We collect odds from all major sports (soccer, football, tennis, baseball, basketball, hockey and more) and cover moneyline, handicaps (spread) and over/under (totals) arbitrages.

An Arbitrage is a situation where bookmakers odds differ so much that by betting on all outcomes of the event or backing and laying the same outcome at different bookmakers you are guaranteed a RISK FREE profit (click here for additional information or simply view our top arb details).

A Bonus Arbitrage is a result of added sign up or deposit bonuses to your actual stake, so the total actual stake (without the bonuses) is substantially lower than your winnings for any outcome.
