Does its posted price hold?
Of 48 20Bet prices Omenizer flagged as market-beating in the last 90 days, 40% were still there or better when we looked again; 60% 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 20Bet's whole board.
How big is the site?
20bet.com ranks #107,545 among the world's million most-visited domains (Tranco, 2026-08-31). Popularity, not quality — a big site can still price badly.

Who runs 20Bet

Operator: Starsten Limited. (source, checked 2026-08-15)

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

In the last 90 days, 20Bet posted the board-leading price on 48 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 6.93% margin means that, on a typical 20Bet market, prices pay out 6.93% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
