Does its posted price hold?
Of 84 betwhale prices Omenizer flagged as market-beating in the last 90 days, 33% were still there or better when we looked again; 67% 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 betwhale's whole board.

Who runs betwhale

Operator: Crypto white-label group (platform unidentified). (reported — verification in progress) Sibling brands under the same operator: BC.Game, betplay, rivalry.

Availability: accessible from US. (reported — verification in progress)

In the last 90 days, betwhale posted the board-leading price on 84 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 8.33% margin means that, on a typical betwhale market, prices pay out 8.33% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
