🔄 What is Sports Betting Arbitrage?
Arbitrage betting (arb) is a risk-free strategy that guarantees profit regardless of the outcome. By betting on all possible outcomes of an event across different sportsbooks with varying odds, you lock in a profit.
Sportsbooks often have different odds for the same event. When the combined implied probability of all outcomes is less than 100%, an arbitrage opportunity exists. Bet the calculated stakes on each outcome to guarantee profit.
Arbitrage exists when: (1 / Odds A) + (1 / Odds B) < 1. Your profit percentage = 1 - [(1/Odds A) + (1/Odds B)].
📊 Arbitrage Example: NFL Game
| Sportsbook | Team A Odds | Team B Odds | Stake | Payout |
|---|---|---|---|---|
| Sportsbook A | +150 (2.50) | -120 (1.83) | $400 | $1,000 |
| Sportsbook B | +120 (2.20) | -110 (1.91) | $547 | $1,000 |
| Total Investment | $947 | Guaranteed Return $1,000 |
||
| Profit: $53 (5.6% ROI) — Risk-Free! | ||||
In this example, you bet $400 on Team A at Sportsbook A and $547 on Team B at Sportsbook B. Regardless of which team wins, you receive $1,000, making $53 profit with zero risk.
