Arbitrage betting, sometimes shortened to “arb betting” or referred to as a “surebet,” may seem a bit daunting at first, but really it’s quite a simple method of going about your sports betting. If you’re aware of what line shopping means, you’ve already got a leg up on understanding arbitrage betting.
Line shopping refers to the strategy of creating an account with several different sportsbooks so as to take advantage of any discrepancies in their individual odds. All sportsbooks are not created equal, and the same goes for their odds.
For example, while sportsbook A might have a certain betting market at -125 odds, sportsbook B might have the same market at +100 odds, which would mean that you get a lot more value by betting on that specific market with sportsbook B.
Arbitrage betting is similar in that it requires bettors to have accounts with several different sportsbooks and to stay abreast of the differing odds on those different sportsbooks. Basically, every sportsbook creates their own odds for each event, and the point of arbitrage betting is to identify the differences between the odds at different sportsbooks and take advantage of that.
It’s worth noting that opportunities for arbitrage betting are exceedingly rare, but they are by far the most common for head-to-head markets because there are only two outcomes, which makes the process much more simple. The two players or teams going head to head will likely have to be pretty evenly matched as well.
For example, let’s say the Toronto Raptors and Boston Celtics are playing each other in the NBA. There are no ties in the NBA, so this is a simple betting market with only two outcomes, which is ideal for arbitrage betting.
Sportsbook A might have the Raptors moneyline at +105 and the Celtics at -120, but because the teams are so evenly matched, Sportsbook B might have the Raptors moneyline at -120 and the Celtics at +105. Arbitrage betting would mean you bet on the Raptors with Sportsbook A and bet on the Celtics with Sportsbook B, thereby guaranteeing that you come away a winner.
