How It Works

Understanding arbitrage and expected value

Arbitrage Betting

An arbitrage opportunity exists when the combined implied probabilities across different bookmakers sum to less than 100%. By placing proportional bets on all outcomes, you guarantee a profit regardless of the result.

If Σ (1/odds) < 1.0 → arb exists

The profit margin equals 1 minus the sum of implied probabilities. Higher margins mean bigger guaranteed returns.

Expected Value (EV)

A value bet exists when the true probability of an outcome is higher than what the odds imply. The expected value quantifies the long-run edge per unit staked.

EV = (True Prob × Decimal Odds) − 1

Consensus probability is derived by aggregating odds from multiple sources. Positive EV means the bet is mathematically profitable over time.
