Best-Value Betting Sites
A betting site's margin is the built-in cost of betting with them: how far their prices sit above a fair 100% market. We measure it from the odds each betting site actually publishes: every complete market they price, averaged. Lower is better for you. See how we measure.

margin across 164 markets.
Rankings reflect the markets each betting site actually prices in the leagues we scan; sites pricing very few markets are excluded until we have enough measurements. This is measured data, not a paid ranking. We list every licensed betting site whether or not they pay us.
