What is Arbitrage Betting?
Arbitrage betting (or "arbing") is a strategy that exploits differences in odds between sportsbooks to guarantee a profit regardless of the outcome. When the combined implied probabilities of all outcomes fall below 100%, an arbitrage opportunity exists.
How Arbitrage Works
Different sportsbooks often have different opinions on the same event, leading to varying odds. By betting on all outcomes at the best available odds across multiple books, you can lock in a guaranteed profit.
Example:
- Book A: Team A at +150 (40% implied)
- Book B: Team B at -130 (56.5% implied)
- Total implied: 96.5% (under 100% = arbitrage!)
Finding Arbitrage Opportunities
- Compare multiple books: The more books you monitor, the more opportunities
- Act fast: Arb opportunities disappear quickly as odds adjust
- Focus on liquid markets: Major sports have more price discrepancies
- Use odds comparison tools: Manual searching is too slow
Risks and Considerations
- Account limitations: Sportsbooks may limit or close accounts of known arbers
- Odds movement: Odds can change between placing bets
- Bet limits: You may not be able to place the full calculated stake
- Errors: Double-check all calculations before betting
