OddsAccuracy is an independent football analytics platform that evaluates how accurately bookmakers estimate match probabilities. The platform applies Brier-score-based metrics to measure probability calibration, short-term accuracy dynamics, and market efficiency across leagues, operators, and time windows.
OddsAccuracy focuses exclusively on descriptive and methodological analysis of odds behavior. It does not provide betting tips, predictions, or wagering recommendations. All insights are derived from publicly available odds data and are intended to support transparency and understanding of bookmaker accuracy rather than decision-making guidance.
