Arbitrage betting is a strategy that exploits discrepancies in odds offered by different bookmakers on the same event, allowing bettors to guarantee a profit regardless of the outcome. In the sports betting context, this works by placing simultaneous bets on all possible outcomes of an event at different sportsbooks, where the odds allow for a situation where the total amount wagered results in a profit. For example, if one bookmaker offers odds of +200 on Team A to win and another offers +150 on Team B, a bettor can place calculated bets on both teams that ensure a return that exceeds the total investment, regardless of which team ultimately wins.
