Frequently Asked Questions
What is arbitrage betting?
Arbitrage betting exploits odds differences between sportsbooks to guarantee profit regardless of outcome. When combined implied probabilities total less than 100%, you can bet both sides and profit no matter who wins.
How do I find arbitrage opportunities?
Compare odds across multiple sportsbooks for the same event. Arb opportunities typically appear when one book has favorable odds on one side while another has favorable odds on the opposite side. They're most common in less popular markets.
Why do sportsbooks allow arbitrage?
Most sportsbooks try to prevent arbitrage by limiting winning bettors and monitoring for arb patterns. Odds discrepancies happen due to different risk management strategies and the competitive market for customers.
What are the risks of arbitrage betting?
Risks include: odds changing before both bets are placed, sportsbook limits or void bets, account restrictions for suspected arb betting, and errors in calculations. Always verify current odds before placing any wagers.
