What is arbitrage betting?
Arbitrage betting, often called "arbing" or a "sure bet", means betting on every outcome of a market at different sportsbooks when the prices are mismatched. When the combined implied probability falls below 100%, you can split a stake so that you profit regardless of the result.

Frequently asked questions
Is arbitrage betting legal?
Yes, arbitrage betting is legal. However, sportsbooks dislike it and may limit stakes or close the accounts of bettors they identify as arbers.
How often do arbitrage opportunities appear?
They are uncommon and short-lived. Odds move quickly as books adjust their prices, so most arbs exist for only a few minutes.
