In the last 90 days, BetMGM posted the board-leading price on 72 signals flagged by Omenizer's detection engine.
The margin is the bookmaker's built-in fee: the amount by which its implied probabilities exceed 100%. A 7.30% margin means that, on a typical BetMGM market, prices pay out 7.30% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
FAQ
- Is BetMGM legit?
- BetMGM is operated by MGM Resorts / Entain JV, which does not state a gaming licence on the page where we confirmed its identity.
