OddsAccuracy benchmarks football odds accuracy across operators.
Aggregate OA Score across all included leagues
Ranking based on absolute OA Scores. Lower values indicate higher forecasting accuracy; higher values indicate weaker calibration.

OA Score measures the distance between predicted probabilities and actual football match outcomes. Lower values indicate better calibration and stronger predictive accuracy. Instead of treating odds as simple prices, OddsAccuracy evaluates them as probability forecasts that can be measured, compared, and ranked across bookmakers, leagues, and time windows.
Football odds represent implied probabilities, not guaranteed truths. Bookmakers are often efficient, but their estimates are not perfectly aligned with real match outcomes. Proper evaluation requires probabilistic scoring, calibration analysis, and longitudinal comparison across operators and leagues. OddsAccuracy applies that framework to quantify how accurate football odds really are.
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.
