The data-driven standard for odds accuracy.
OddsAccuracy evaluates how well bookmakers estimate match probabilities using OA Score, a Brier-score-based accuracy framework . Compare operators such as Pinnacle, Bet365, Bwin, and William Hill across opening and closing odds, team accuracy rankings, TAI dynamics, and team predictability analytics.
OddsAccuracy™ provides independent statistical analysis based solely on publicly available odds and match results. All bookmaker names and trademarks belong to their respective owners and are used strictly for comparative, informational, and editorial purposes. Our metrics represent probabilistic evaluations and methodological interpretations—not statements of fact about any operator’s competence, business performance, or regulatory status. OddsAccuracy™ is not affiliated with, endorsed by, or partnered with any bookmaker unless explicitly disclosed.
Values above zero indicate weaker recent accuracy; values below zero indicate stronger recent accuracy.
Dual mode analysis: 1 team + up to 5 bookmakers or 1 bookmaker + up to 5 teams.
The framework is designed to scale as more bookmakers are incorporated.
Teams with the lowest average OA Scores, indicating strong alignment between expected and actual outcomes.
Teams with the highest OA Scores, reflecting large and frequent deviations from expected outcomes.
