In the last 90 days, Jazz Sports posted the board-leading price on 352 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 7.02% margin means that, on a typical Jazz Sports market, prices pay out 7.02% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
FAQ
- Is Jazz Sports legit?
- Omenizer has not yet verified which company operates Jazz Sports or what licence it holds — a gap in our research rather than a finding against the book. Independently of that, Omenizer has measured 10,174 Jazz Sports 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 Jazz Sports?
- Omenizer has not yet verified the company behind Jazz Sports. 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.

- Not established — we have not confirmed a licence for Jazz Sports.
- What is Jazz Sports's betting margin?
- Measured across 10,174 markets in the last 7 days, Jazz Sports's median margin (overround) was 7.02% — rank #62 of 145 bookmakers Omenizer tracks. Lower is better for bettors.
- How often does Jazz Sports have the best odds?

- 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.
