The margin is the bookmaker's built-in fee: the amount by which its implied probabilities exceed 100%. A 6.49% margin means that, on a typical marathon market, prices pay out 6.49% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
FAQ
- Is marathon legit?
- Omenizer has not yet verified which company operates marathon or what licence it holds — a gap in our research rather than a finding against the book. Independently of that, Omenizer has measured 1,628 marathon 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 marathon?
- Omenizer has not yet verified the company behind marathon. We record an operator only when we have read it on the operator's own site or a regulator's register, so this is an unfilled gap rather than a guess we declined to make.
- Is marathon licensed?
- Not established — we have not confirmed a licence for marathon.
- What is marathon's betting margin?
- Measured across 1,628 markets in the last 7 days, marathon's median margin (overround) was 6.49% — rank #43 of 141 bookmakers Omenizer tracks. Lower is better for bettors.
- How often does marathon have the best odds?
- Where at least five independent operators priced the same market (clone brands sharing one price feed count once), marathon posted the single best price 3.5% of the time over the last 7 days.
- How is marathon's margin measured?
- Omenizer records every price on every tracked market, converts them to implied probabilities, and sums each market's sides; the amount over 100% is the bookmaker's margin. The figure here is the median across all of the book's observed markets — measured, not quoted from marketing material.
