The total amount you want to distribute across all outcomes
Arbitrage betting (also called "arbing" or "sure betting") is a strategy where you bet on all possible outcomes of a sporting event across different sportsbooks. When sportsbooks disagree on the odds enough, you can guarantee a profit no matter what happens.
The key: sportsbooks set odds independently. Sometimes Book A offers great odds on Team 1 while Book B offers great odds on Team 2. If the combined implied probabilities fall below 100%, you have an arbitrage opportunity.
Example:
Book A offers Team 1 at +180 (decimal 2.80). Book B offers Team 2 at -150 (decimal 1.667).
Arb % = (1/2.80) + (1/1.667) = 0.357 + 0.600 = 0.957
Profit % = (1/0.957) - 1 = 4.49%
On a $1,000 total stake, you would earn $44.90 guaranteed profit regardless of which team wins.
To guarantee equal profit on every outcome, you allocate your total stake proportionally based on implied probabilities:
This ensures that no matter which outcome wins, the payout is the same. The calculator above does this math for you instantly.
2-way arbs cover two outcomes (win/lose). These are common in moneyline bets for sports like basketball, baseball, tennis, and MMA where ties are not possible or the market only has two sides.
3-way arbs cover three outcomes (win/draw/lose). These are common in soccer, hockey (regulation time), and other sports where a draw is a possible result. The math is the same, just with an extra outcome added to the equation.
3-way arbs tend to have higher profit margins because there are more sportsbooks and more odds to compare, creating bigger pricing gaps. However, they require splitting your stake three ways, which means each individual bet is smaller.
Speed matters. Arbitrage opportunities often last only minutes before sportsbooks adjust their lines. Use tools that scan odds in real time to find them before they disappear.
Account for fees. Some sportsbooks charge withdrawal fees or have unfavorable exchange rates. Factor these into your profit calculations.
Manage your accounts. Sportsbooks may limit or close accounts that consistently take advantage of arb opportunities. Use a variety of books and mix in regular bets to stay under the radar.
Start small. Practice with small stakes to understand the mechanics before committing large amounts. Mistakes in arbing can be costly.
