The margin is the bookmaker's built-in fee: the amount by which its implied probabilities exceed 100%. A 8.06% margin means that, on a typical sport888 market, prices pay out 8.06% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
FAQ
- Is sport888 legit?
- Omenizer has not yet verified which company operates sport888 or what licence it holds — a gap in our research rather than a finding against the book. Independently of that, Omenizer has measured 753 sport888 markets in the last 7 days against the rest of the market, so its prices are observable rather than taken on trust. We publish the checks we can evidence and flag the ones we cannot — we do not certify bookmakers.
- Who owns sport888?
