Arbitrage betting exploits discrepancies in odds offered by different sportsbooks on the same event to guarantee a profit regardless of the outcome. Bettors identify situations where the combined implied probabilities across all potential outcomes are less than 100%, effectively ensuring that a series of wagers on each outcome will result in a net profit due to the favorable odds. By strategically placing bets across multiple platforms, the bettor locks in a guaranteed return, capitalizing on the market inefficiencies created by varying odds.
