Arbitrage betting, also known as sure betting or miracle betting, is a strategy that allows you to make a profit by betting on all possible outcomes of an event with different bookmakers. This strategy takes advantage of discrepancies in odds between different bookmakers. In this beginner’s guide, we’ll explore how arbitrage betting works and how you can use OddsRun to make money from it.

What is Arbitrage Betting?

Arbitrage betting involves placing bets on all possible outcomes of an event with different bookmakers to guarantee a profit, regardless of the outcome. By exploiting differences in odds between bookmakers, arbitrage bettors can lock in a profit.

How Does Arbitrage Betting Work?

Arbitrage opportunities arise when different bookmakers offer different odds on the same event. By placing bets on all possible outcomes with different bookmakers, you can ensure a profit, regardless of the outcome of the event.

Example of Arbitrage Betting:

Let’s say you’re betting on a tennis match between Player A and Player B.

  • Bookmaker X offers odds of 2.00 on Player A to win.
  • Bookmaker Y offers odds of 2.20 on Player B to win.

To calculate if there is an arbitrage opportunity:

  1. Calculate the implied probability for each outcome:
    • For Player A: 1 / 2.00 = 0.50 (or 50%)
    • For Player B: 1 / 2.20 = 0.45 (or 45.45%)
  2. Add the implied probabilities together:
    • 0.50 + 0.45 = 0.95 (or 95%)
  3. Check if the total implied probability is less than 1 (100%). If it is, there is an arbitrage opportunity.

In this case:

  • 1 – 0.95 = 0.05 (or 5%)

There is a 5% arbitrage opportunity.
