Understanding arbitrage and expected value
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.
The profit margin equals 1 minus the sum of implied probabilities. Higher margins mean bigger guaranteed returns.
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.
Consensus probability is derived by aggregating odds from multiple sources. Positive EV means the bet is mathematically profitable over time.

Past performance does not guarantee future results. Sports betting and prediction markets carry inherent risk — never stake more than you can afford to lose.
