Arbitrage betting involves placing bets on all possible outcomes of an event at different sportsbooks that offer differing odds, ensuring a guaranteed profit regardless of the outcome. For example, if one sportsbook offers odds of 2.10 for Team A to win and another offers odds of 2.10 for Team B to win, you can bet on both teams at these odds. No matter which team wins, you will make a small profit. This strategy is low-risk and can be facilitated by software tools that identify these opportunities.
