How to Use Betting Exchanges to Beat the Margin
Betting exchanges cut out most of the bookmaker's margin and let you bet against outcomes. Here's how to use them to get better prices and more control.
Betting exchanges are one of the sharpest tools for serious bettors: you bet against other people, not the house, so the built-in margin is tiny. This means better prices and the ability to lay as well as back. This guide shows you how to use them, building on what is a lay bet? (betting exchanges explained).
Lower margins, better prices
Exchanges charge a small commission on winnings instead of a big overround, so their prices are usually closer to true probability — often the best available, as in line shopping.
Even after commission, you frequently beat traditional bookmakers.
Back and lay
On an exchange you can back (bet for) or lay (bet against) an outcome, opening up strategies impossible with bookmakers. Laying lets you profit from selections you think are overrated.
Remember laying carries liability, so manage stakes carefully.
They don't restrict winners
Unlike bookmakers, exchanges welcome winning customers — there's no gubbing. That makes them essential once you're restricted elsewhere.
They also power matched betting and trading.
Watch liquidity and commission
Exchanges rely on other users, so niche markets can have thin liquidity and worse prices. Factor commission into every comparison, and use our calculators to work out true value.
For popular markets, though, exchanges are hard to beat on price.
