| Handicaps / spreads | 8.67% |
The margin is the bookmaker's built-in fee: the amount by which its implied probabilities exceed 100%. A 6.28% margin means that, on a typical BetDEX market, prices pay out 6.28% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
