Who runs Casumo

Availability: licensed in CA, GB, SE.
In the last 90 days, Casumo posted the board-leading price on 61 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 7.25% margin means that, on a typical Casumo market, prices pay out 7.25% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
