Arbitrage Opportunities
Grouped by game, sorted by profitHow it works: Arbitrage exists when the combined implied probability across two sportsbooks falls below 100%. The quality score (Q) is a composite of three factors: persistence (how long the arb has survived vs sport median), profit margin width (wider = more executable), and pricing normality (lower z-score = less likely to be a glitch). Outlier-flagged arbs have one leg priced >3 standard deviations from consensus — these carry higher void risk but may also represent genuine mispricings or prediction market divergence.
