Frequently Asked Questions
What is arbitrage betting?
Arbitrage betting (or "arbing") is a strategy where you bet on all possible outcomes of an event using different bookmakers, guaranteeing a profit regardless of the result. This is possible when bookmakers have different opinions on the odds.
How do I find arbitrage opportunities?
Compare odds across multiple bookmakers for the same event. When the sum of implied probabilities (1/decimal odds) is less than 1 (or 100%), an arbitrage opportunity exists.
Is arbitrage betting legal?
Arbitrage betting is legal in most jurisdictions. However, bookmakers may limit or close accounts of bettors they suspect of arbing, as it reduces their profits.
What are the risks of arbitrage betting?
Risks include: odds changing before you place all bets, account limitations, human error in calculations, and the need for significant capital across multiple bookmaker accounts.
What profit margins are typical for arbitrage?
Typical arbitrage margins range from 1-5%. While small, these are guaranteed profits. Higher margins are rare and may indicate an error or a very short-lived opportunity.
