Learn How Arbitrage Betting Works: A Comprehensive Guide with Examples, Analogies, and Formulas

Arbitrage betting, or "arbing," is a popular low-risk betting strategy that allows you to make a guaranteed profit by taking advantage of differing odds across multiple bookmakers. This betting method is all about finding value and exploiting market inefficiencies. In this comprehensive guide, we'll explore the basics of arbitrage betting, including examples, analogies, and formulas to help you understand and capitalize on this exciting betting strategy.

What is Arbitrage Betting?

Arbitrage betting is a technique used by bettors to guarantee a profit regardless of the outcome of a sporting event. This is achieved by placing bets on all possible outcomes with different bookmakers, ensuring that the total amount wagered results in a profit, no matter the result. Arbing is possible when the combined odds from multiple bookmakers create an opportunity for profit.

An Analogy: The Currency Market

To better understand the concept of arbitrage betting, consider the currency market. Imagine you have 1,000 US dollars, and you notice that the exchange rate for US dollars to Euros is 0.90 with one currency exchange company, while another company offers a rate of 0.92 for Euros to US dollars. You could exchange your 1,000 US dollars for 900 Euros at the first company and then immediately exchange your 900 Euros back to US dollars at the second company, resulting in 1,008 US dollars. You've made a profit of 8 US dollars without taking any risk!

Arbitrage Betting Example

Let's look at a simple example of arbitrage betting in a tennis match between Player A and Player B. Suppose you find the following odds at two different bookmakers:

    Bookmaker 1:
      Player A: 1.60
      Player B: 2.50
    Bookmaker 2:
      Player A: 1.55
      Player B: 2.60

By comparing the odds, you can see that Bookmaker 1 offers better odds for Player A, while Bookmaker 2 offers better odds for Player B. To capitalize on this arbitrage opportunity, you'll place bets on both players with the respective bookmakers.

Arbitrage Betting Formula

To calculate the optimal bet amounts, you'll need to use the arbitrage betting formula:

1. Determine the total investment (T) you want to make.

2. Calculate the individual bet amounts by dividing the total investment by the respective odds:

      Bet on Player A: T / Odds_Player A
      Bet on Player B: T / Odds_Player B

In our example, let's say you want to invest 100 USD (T = 100). The optimal bet amounts would be:

      Bet on Player A: 100 / 1.60 = 62.50 USD
      Bet on Player B: 100 / 2.60 = 38.46 USD

Now, no matter which player wins, you're guaranteed a profit


Arbitrage betting is an exciting and low-risk strategy that can provide consistent returns when executed correctly.
