Arbitrage Betting

The Guide to Risk-Free Profits

Arbitrage betting – or “arbing” – is a strategic method that exploits pricing discrepancies across bookmakers to guarantee profits, regardless of a sporting event’s result. This guide unveils how arbitrage betting works and discusses its advantages and challenges.


What is Arbitrage Betting?

Arbitrage betting involves placing opposing bets on all possible outcomes of an event at odds that ensure a profit. These opportunities arise when bookmakers assess odds differently due to market delays, errors, or regional biases.

Example:

  • Tennis Match:
    • Bookmaker A: 2.1 odds on Player X.
    • Bookmaker B: 2.1 odds on Player Y.
      By staking £100 on each player:
    • Profit: £210 (if either wins) – £200 total stake = £10 guaranteed.

How Arbitrage Betting Works: Step-by-Step

1. Identify Arbitrage Opportunities

Convert odds to implied probabilities and ensure their sum is <100%.

  • Formula:
    Implied Probability=1Odds×100Implied Probability=Odds1​×100.
  • Example:
    • Bookmaker A: 2.0 odds on Team X → 50% probability.
    • Bookmaker B: 2.5 odds on Team Y → 40% probability.
    • Total: 90% → 10% profit margin.

2. Calculate Stakes

Distribute your total stake to ensure equal returns.

  • Formula:
    Stake on Outcome A=Total Stake×Odds BOdds A+Odds BStake on Outcome A=Odds A+Odds BTotal Stake×Odds B​.
  • Example:
    • Total Stake: £1,000.
    • Stake on Team X: 1,000×2.52.0+2.5=£555.562.0+2.51,000×2.5​=£555.56.
    • Stake on Team Y: £444.44.
    • Profit: ~£111 regardless of outcome.
