Who runs Smarkets

The margin is the bookmaker's built-in fee: the amount by which its implied probabilities exceed 100%. A 0.78% margin means that, on a typical Smarkets market, prices pay out 0.78% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
FAQ
- Is Smarkets legit?
- Omenizer has not yet verified which company operates Smarkets or what licence it holds — a gap in our research rather than a finding against the book. Independently of that, Omenizer has measured 454 Smarkets 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 Smarkets?
- Omenizer has not yet verified the company behind Smarkets. 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 Smarkets licensed?
- Not established — we have not confirmed a licence for Smarkets.
- What is Smarkets's betting margin?

- How often does Smarkets have the best odds?
- Where at least five tracked books priced the same market, Smarkets posted the single best price 16.2% of the time over the last 7 days.
- How is Smarkets'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.
