Of 715 SportsBetting.ag prices Omenizer flagged as market-beating in the last 90 days, 52% were still there or better when we looked again; 48% had moved against the bettor and 0% had the market pulled. Measured only on prices we flagged as outliers — the ones most likely to be corrected — so read it against other books here, not as a share of SportsBetting.ag's whole board.

Who runs SportsBetting.ag

Operator: BetOnline Group. (reported — verification in progress) Sibling brands under the same operator: BetOnline.

In the last 90 days, SportsBetting.ag posted the board-leading price on 715 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 6.00% margin means that, on a typical SportsBetting.ag market, prices pay out 6.00% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
