Betting Exchanges in the US: Best Sites and How They Work

Availability still varies by state, and some states, including Nevada, restrict prediction market sports contracts. A betting exchange is a marketplace where bettors wager against each other instead of against a sportsbook, with the exchange matching the two sides and holding both stakes until the event settles. If you want a deeper walkthrough of the model itself, the guide to peer-to-peer betting covers it.

However, opting to use the basic plan would mean any free games, rewards or offers are removed. They also offer new exchange customers a sign-up promotion of bet £20 (using a betting sites debit card) on their exchange and they will refund £20 to your balance as cash if your bet loses. One additional feature that Betfair offers is a dedicated Each Way market on Horse and greyhound races. The increased liquidity means better available back and lay odds which is essential for Betfair Trading, Matched betting and other betting strategies.

Having more than one betting exchange account is 100% essential if you are using the exchange to trade. Liquidity is the amount of money available to bet either with or against in a betting exchange market. However, if the liquidity is not present at a better price then it is a false scenario and the sportsbook is the better place to make the bet. Often betting exchanges are lauded for offering better prices in comparison to traditional online bookmaker sportsbooks.

Bonus funds are separate to cash funds and subject to 10x wagering requirement (bonus funds). Full T&Cs apply to any offers. Qualifying bet must settle, excluding cash outs. #AD 18+ Once registered, turn on notifications for free bets, offers and proper boosts. Void/cashed out bets excluded.

By doing that, pretty much every market going should be covered, you have a backup if one were to be out of service and you get to check the odds for the same event on all of them. It is extremely important that you check that you have backed and layed the same event/result. So you place a back bet of £20 on Estonia to win at Corals and place a lay bet of £16.67 on Estonia not winning at the exchange.

We thought it would be helpful to find a full commission rate comparison for betting exchange sites in one place, as when we were researching for this article we couldn’t find one online. The “lay” is more like a traditional bet with a bookie, so with exchange betting (and this is simplifying it somewhat) you can place a bet, or be the bookmaker. The low commission rates make it an excellent option, and they even do a brilliant and influential podcast that is well worth a listen. Matchbook has comparable liquidity to Betfair on horse racing and major events, while the app, and site, has a slick feel across its platform. In the past, Matchbook has been the most generous of all the exchanges with regular 0% commission welcome offers which plays well against Betfair being the highest commission rate at 5%.

The Exchange provides the platform for these transactions to happen and they take a small percentage (usually 2%) from winning bets as a commission.

You can check any two-sided price this way with the no-vig calculator. So prices come from supply and demand, you can post your own number, and a bettor who wins consistently is a good customer rather than a risk to limit. One bettor offers a price on a side, another bettor accepts the opposite side at that price, and the exchange holds both stakes until the game settles. The main betting exchange sites open to US bettors in 2026 are BettorEdge, Novig, ProphetX, Kalshi and Polymarket US. A betting exchange is a marketplace where you bet against other bettors instead of a sportsbook, and the exchange earns by matching the two sides rather than by pricing a margin into the odds.

So join me as I go through betting exchange features, pros/cons, and how to use them in your favor. For example, you might place a lay bet on a horse not to win a race. In gambling, a lay bet is a wager that something will not happen. Lay betting can be a great way to make money, but it is also important to remember that you are taking on additional risk.
