Arbitrage Alerts

Sports betting arbitrage (or "arbing") is a strategy where you place bets on all possible outcomes of an event across different sportsbooks, guaranteeing a profit regardless of the result. This is possible when the combined implied probabilities from the best available odds across books total less than 100%.

For example, if Book A offers Team A at +150 (40% implied) and Book B offers Team B at +120 (45.5% implied), the combined implied probability is 85.5%, meaning there is a 14.5% guaranteed profit margin. By staking proportionally on each outcome, you lock in profit no matter who wins.

How Our Scanner Works

We scan odds from 15+ US sportsbooks across 13 sports every 3 minutes. For each event, we compare moneyline, spread, and total odds to find opportunities where the best available prices create a combined implied probability under 100%. We also calculate optimal stake sizing so you know exactly how much to bet on each leg.

Important Considerations

• True arbs are rare and fleeting. They typically last seconds to minutes before odds adjust.
• You need accounts at multiple sportsbooks to take advantage of arb opportunities.
• Some sportsbooks may limit or close accounts that consistently exploit arbitrage.
• Low-hold opportunities (near-arbs) are more common and still represent excellent value compared to typical sportsbook margins.
• Always verify the odds are still available before placing your bets.
