Arbitrage betting — often called "sure bets" or "arbs" — is a strategy where you place bets on all possible outcomes of an event across different bookmakers, guaranteeing yourself a profit regardless of the result.
Bookmakers set odds independently. When they disagree on the probability of an outcome, the combined implied probability of all outcomes can drop below 100%. This gap is your profit.
Example:
By betting $47.62 on Team X at Bookmaker A and $47.62 on Team Y at Bookmaker B, you stake $95.24 total and receive $100 regardless of who wins. That's a $4.76 guaranteed profit.
Three-outcome arbs are more common in soccer but require more capital and faster execution.
1. Different opinions: Bookmakers have different models and may disagree on probabilities.
2. Market movement: When sharp money moves one line, other books may be slow to adjust.
3. Regional bias: Books in different markets may weight local teams differently.
4. Liquidity differences: Smaller books may offer better odds to attract action.
