To find matches for arbitrage betting, you need to compare the odds offered by various sportsbooks for a particular event and look for differences in the odds that allow you to place bets on all possible outcomes with a guaranteed profit. For example, imagine that Bookie A is offering odds of +120 for the New York Yankees to win a baseball game, while Bookie B is offering odds of +105 for the Boston Red Sox to win. By placing bets on both teams with the appropriate stake, you can guarantee a profit regardless of which team wins the game.
