Plus 2.0% commission. Matchbook charges commission on winnings rather than building a margin into its prices, so the figure above understates what it costs to bet there: all in, about $3.16 per $100 staked (their published rate). Compare venues on all-in cost →

Who runs Matchbook

The margin is the bookmaker's built-in fee: the amount by which its implied probabilities exceed 100%. A 2.21% margin means that, on a typical Matchbook market, prices pay out 2.21% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.

FAQ

Is Matchbook legit?
Omenizer has not yet verified which company operates Matchbook or what licence it holds — a gap in our research rather than a finding against the book. Independently of that, Omenizer has measured 4,137 Matchbook 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 Matchbook?
Omenizer has not yet verified the company behind Matchbook. 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 Matchbook licensed?
Not established — we have not confirmed a licence for Matchbook.
What is Matchbook's betting margin?
Measured across 4,137 markets in the last 7 days, Matchbook's median margin (overround) was 2.21% — rank #2 of 145 bookmakers Omenizer tracks. Lower is better for bettors.
How often does Matchbook have the best odds?
Where at least five independent operators priced the same market (clone brands sharing one price feed count once), Matchbook posted the single best price 27.2% of the time over the last 7 days.
How is Matchbook'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.
