A bookmaker sets a price and takes the other side of your bet. A betting exchange does neither. It is a marketplace where one customer backs an outcome, another lays it, and the exchange matches the two and charges a fee on the winner’s profit.
That simple idea has had a turbulent few years. One long-running exchange has been absorbed by a rival, and in the US the exchange model has moved into federally regulated prediction markets. This guide explains what a betting exchange is and where the market stands in late 2026.
Betting Exchange Meaning in One Paragraph
A betting exchange is a platform where customers bet against each other instead of against the house. Backing means betting that something will happen. Laying means betting that it will not, which makes you the bookmaker for that bet. The exchange shows the best available back and lay prices, matches orders that agree on a price, holds the money of both sides and settles the market when the result is known. It earns commission, usually a percentage of each customer’s net winnings in a market, so it has no direct interest in who wins.
Betting Exchange vs Bookmaker
| Betting exchange | Bookmaker | |
|---|---|---|
| Who sets the odds | Customers, through the bids and offers they place | The bookmaker’s traders and models |
| Who you bet against | Another customer | The bookmaker |
| How it makes money | Commission on net winnings | Margin built into the odds |
| Can you lay an outcome? | Yes | No |
| What happens to winning customers | They pay commission; a very small group may face extra fees | Stakes may be limited or accounts restricted |
Because there is no margin in the price, exchange odds on popular markets are often close to fair value. The trade-off is liquidity. A bet only goes through if someone else wants the other side, so small or niche markets can have wide gaps between back and lay prices. Our comparison of betting exchange vs sportsbook goes into this in more depth.

Who Runs Betting Exchanges in 2026
Betfair Exchange
Betfair, owned by Flutter, is still the reference point. Flutter’s annual report for 2025 says it offers exchange betting through Betfair in the UK and Ireland and in Brazil, and that Betfair is locally regulated in Denmark, Italy, Malta, Romania and Spain. Flutter doesn’t publish exchange revenue on its own. The exchange sits inside a line called other products, which made up 3% of group revenue in 2025. In early November 2026 Flutter also announced it was closing Betfair’s Brazilian operations and moving that business to Betnacional, without saying what this means for the exchange product. For a closer look at the brand, see our definition of Betfair Exchange.
Matchbook and the end of Betdaq
Betdaq, one of the oldest exchanges, no longer runs on its own. Matchbook bought it in 2026. Betdaq stopped taking bets on 21 October 2026, customers could withdraw until 4 November, and the two pools of liquidity are being combined. Matchbook’s standard commission is 2% of net winnings.
Smarkets
Smarkets has long charged 2% commission in the UK. In March 2026 it said it was seeking approval from the US Commodity Futures Trading Commission (CFTC) to run a prediction market there.
The US Shift From Exchanges to Prediction Markets
State-licensed sports exchanges have struggled in the US. Prophet Exchange launched in New Jersey in 2022 and closed in May 2024. Sporttrade, which held licences in New Jersey, Arizona, Colorado, Iowa and Virginia, stopped taking sports bets on 25 May 2026.
Both have come back as federally regulated businesses. ProphetX received CFTC approval as an exchange and clearing house in June 2026 and launched nationwide that month. Sporttrade received its CFTC registrations on 3 November 2026. They join prediction markets such as Kalshi and Polymarket, which list contracts on sports results.
The legal picture is unsettled. The CFTC proposed new rules for these contracts in June 2026 but had not finalised them by November. Federal appeals courts have split: the Third Circuit sided with Kalshi in April 2026, while the Ninth and Sixth Circuits ruled against it in August and September. Petitions have been filed with the Supreme Court, which had not agreed to hear any of them by early November.
Why Betting Exchanges Matter to Operators
For an operator, an exchange is a different business from a sportsbook. It doesn’t carry the risk of a result going the wrong way, but it needs enough customers on both sides of each market to work. That is why new exchanges either share liquidity with an existing one, focus on a narrow set of markets, or use market makers who post prices on both sides.
Exchange prices are also useful even if you never run one. Many sportsbook traders watch exchange odds as a signal of where the market thinks the true probability lies. Our article on how a betting exchange works explains the matching process step by step.
FAQ About Betting Exchanges
Is a betting exchange legal?
It depends on the country. Betfair operates under licences in the UK, Ireland and several EU markets. In the US, sports exchanges now mostly operate as CFTC-regulated prediction markets, and several states are challenging them in court.
Can you lose more than your stake on a betting exchange?
When you back, you can only lose your stake. When you lay, you can lose your liability, which is the stake you accept multiplied by the odds minus one. Laying at high odds can put a lot of money at risk.
Do betting exchanges limit winning customers?
An exchange doesn’t take the other side of your bets, so it has less reason than a bookmaker to restrict winners. Betfair does charge a small group of very profitable customers an Expert Fee on top of commission. Our guide to Betfair commission fees explains how it works.
What is the difference between a betting exchange and a prediction market?
Both match customers against each other. In the US, prediction markets are regulated by the CFTC as financial exchanges, while traditional betting exchanges are licensed by gambling regulators.
A betting exchange is a marketplace, not a bookmaker. In 2026 the model is consolidating in Europe and being rebuilt under financial regulation in the US. If you want to try one, our step-by-step guide to using a betting exchange is the place to start.
