BetBox is a collective intelligence method for gambling on sports, aimed at providing precise evaluation of games outcomes probability. This method learns from the collective intelligence provided by online bookmakers in order to bet against the weakest predictor. Moreover, thanks to the Kelly criterion, it optimizes the bets distribution over multiple online bookmakers to maximize the margin of win and to minimize the risk of loss. This whitepaper is aimed at introducing BetBox by means of validation results achieved for some case studies.
