How Arbitrage Betting Works

Understanding the mathematics behind guaranteed profits

What is Arbitrage?

Arbitrage betting involves placing bets on all possible outcomes of an event across different sportsbooks, taking advantage of odds discrepancies to guarantee a profit regardless of the outcome.

When Does It Work?

An arbitrage opportunity exists when the sum of the implied probabilities from different sportsbooks is less than 100%. This creates a mathematical edge.

How do I identify arbitrage opportunities?

For an arbitrage to exist the absolute value of the positive odds need to be higher than the absolute value of the negative odds.

Example Calculation

Book A: Team X +120 (implied prob: 45.45%)
Book B: Team Y -110 (implied prob: 52.38%)
Total: 97.83% < 100% = Arbitrage!

Important Notes

  • Always verify odds before placing bets
  • Consider betting limits and account restrictions
  • Factor in potential fees or commissions
