Arbitrage betting, also known as “arbing”, is a betting strategy that allows punters to secure a guaranteed profit irrespective of a game’s outcome. This professional guide will delve into the principles and intricacies of arbitrage betting to help both beginners and experienced bettors enhance their betting strategies.

What is Arbitrage Betting?

Example of Arbitrage Betting

Let’s consider a simple example of arbitrage betting in a tennis match.

Suppose you have Player A and Player B competing in an upcoming match. Two different bookmakers are offering the following odds for each player to win:

Bookmaker 1:

  • Player A to win: Odds 1.8
  • Player B to win: Odds 2.2

Bookmaker 2:

  • Player A to win: Odds 2.1
  • Player B to win: Odds 1.9

The discrepancies in the odds offered by the two bookmakers create an arbitrage opportunity.

Now, let’s suppose you have $100 to bet. You split your total stake into two, betting on both outcomes in such a way that you guarantee a profit irrespective of who wins.

Here’s how you can do it:

  • Bet $52.63 on Player A with Bookmaker 2 at odds of 2.1.
  • Bet $47.37 on Player B with Bookmaker 1 at odds of 2.2.

Let’s work out the potential outcomes:

  • If Player A wins, your return with Bookmaker 2 will be $52.63 * 2.1 = $110.52. Since you bet a total of $100, your net profit would be $110.52 – $100 = $10.52.
  • If Player B wins, your return with Bookmaker 1 will be $47.37 * 2.2 = $104.21. Deducting your total stake, your net profit would be $104.21 – $100 = $4.21.

As you can see, no matter who wins the match, you make a profit. This is the essence of arbitrage betting – you’re playing the system to lock in a profit no matter what the outcome of the event is.

Please note that while this method does offer guaranteed returns if done correctly, it requires precise calculations, quick decision-making, and generally a large bankroll. There is also the risk of being detected by bookmakers and having your account limited or closed.
