How BetSpark identifies value bets

BetSpark uses machine learning models trained on historical match data to estimate the true probability of outcomes in football matches. When our model probability exceeds the market implied probability, the bet carries positive expected value — meaning it is statistically underpriced by the bookmaker.

Expected value is calculated as EV = (model probability × decimal odds) − 1. A positive EV indicates a long-run profitable bet. The BetSpark app shows Kelly-optimal stake sizing to manage bankroll risk.
