Sports Arbitrage betting is the process in which punters can ensure a profit by betting on the same outcome at two different prices. ‘Arbers’ will spot potential opportunities by comparing the prices of hundreds of different sporting events with several online bookmakers. Arbitrage betting requires a large starting bank, and only players who wager significant stakes tend to make a consistent profit using this system. Typically, the margin of profit is between 2-3%, and this requires a large bet in order to take full advantage. For example, in a tennis match – Player A maybe 1.91 with an online sportsbook. A rival betting site could have Player B at 2.20 to be victorious, and this should allow an opportunity for arbitraging. Backing Player A at this price with a stake of $107 would return $204.37. Online Arb calculators are available online to figure out the exact stakes required in order to make a profit. $93 on Player B would be enough to return $204.60 which give the bettor a profit of over $4 regardless of the outcome. This allows either player to prevail, and profit can still be made. Arbitrage has become increasingly popular since the arrival of online sports betting exchanges, although some of them do take a commission, which would eliminate any potential profit. It allows players to exploit significant price differences between multiple online bookmakers. It is increasingly common for punters to find major differences between the more traditional online sportsbooks and the exchanges. However, many operators will have dedicated traders who monitor any major movements in markets. Trying to spot the opportunities is the hardest part of arbitrage betting, and it can sometimes be difficult to place wagers before the prices are brought into line with one another.
