Smarkets vs Betfair Exchange: Which Is Better for Matched Betting?

If you're getting started with matched betting, one of the first decisions you'll need to make is which betting exchange to use. The two main options in the UK are Smarkets and Betfair Exchange. Both are legitimate, well-established platforms — but they differ in ways that matter for matched bettors.

In this guide we'll compare them across every factor that counts: commission rates, liquidity, ease of use, and value for money. By the end you'll know which one to start with and whether you need both.

What is a betting exchange?

A betting exchange is a platform where you bet against other users rather than against a bookmaker. This is essential for matched betting because it allows you to lay a bet — that is, bet against an outcome happening. When you combine a back bet at a bookmaker with a lay bet at an exchange, you cover all possible outcomes and lock in a guaranteed result.

Without an exchange, matched betting simply doesn't work. If you're unfamiliar with how back and lay bets fit together, our getting started guide covers the fundamentals.

Exchanges make their money by charging a small commission on your net winnings. This is one of the most important factors in choosing between them, because lower commission means you keep more of your profit on every single bet.

Smarkets: low commission and simplicity

Smarkets charges a flat 2% commission on net winnings. This is the lowest standard commission rate among UK betting exchanges, and it makes a real difference over time. On a £10 winning lay bet, you pay just 20p in commission compared to 50p on a 5% exchange.

The Smarkets interface is clean, modern, and easy to navigate. It was designed with simplicity in mind, which makes it particularly appealing if you're new to exchanges. Finding a market, checking the odds, and placing a lay bet is straightforward, with none of the clutter that can make other platforms feel overwhelming.

Smarkets also has a solid mobile app for both iOS and Android. The app mirrors the desktop experience closely, so you can place lay bets on the go without any difficulty.

The main limitation of Smarkets is liquidity. Because fewer people use Smarkets compared to Betfair, there is less money available in the market at any given time. For popular events like Premier League football, this is rarely an issue — there's plenty of money available. But for niche sports, lower-league fixtures, or less common bet types, you may find that there isn't enough liquidity to get your lay bet matched at the odds you need.

Betfair Exchange: the market leader

Betfair is the original and largest betting exchange in the world. It handles significantly more volume than any competitor, which means it has the best liquidity across virtually every sport and market. If you need to place a lay bet on an obscure tennis match or a lower-league football game, Betfair is much more likely to have the liquidity you need.

The standard Betfair commission rate is 5%, though this can be reduced. Betfair occasionally runs promotions that lower your rate, and high-volume users can negotiate better terms over time. Some matched bettors report rates as low as 2–3% after sustained activity. Even so, the starting rate is noticeably higher than Smarkets.

Betfair's interface is functional but busier than Smarkets. There is more information on screen at any given time, which can feel cluttered when you're getting started. The mobile app is capable but similarly dense. Once you're used to it, navigation is fine — but the learning curve is steeper.

One advantage of Betfair is the sheer breadth of markets. Beyond standard match-winner bets, Betfair offers lay betting on a huge range of selections — correct scores, Asian handicaps, half-time results, and more. This can be useful for advanced matched betting strategies where you need specific market types.

Head-to-head comparison

How commission affects your profit

Commission might seem like a small detail, but it adds up. Every lay bet you win at the exchange has commission deducted from your winnings. Over hundreds of bets, the difference between 2% and 5% commission is significant.

For example, if you complete 100 lay bets with average net winnings of £10 each, you'd pay £20 in total commission at Smarkets versus £50 at Betfair. That's an extra £30 in your pocket — and the gap only widens the more active you are.

When using our matched betting calculator, make sure you enter the correct commission rate for your exchange. The commission field adjusts your lay stake and expected profit accordingly, so getting it right is essential for accurate results.

Our recommendation

For most beginners, Smarkets is the better choice. The lower commission saves you money from day one, the interface is easier to learn, and the liquidity is perfectly adequate for the popular markets you'll be using during sign-up offers. The £1 minimum bet is also helpful when you're starting out and want to practise with smaller amounts.

As you become more experienced, consider opening a Betfair account as a secondary exchange. You'll find it useful when you need liquidity in niche markets, when Smarkets doesn't have the odds you need, or when you want to take advantage of Betfair's wider range of bet types for advanced strategies.

Many experienced matched bettors use both exchanges side by side — defaulting to Smarkets for the lower commission but switching to Betfair when a specific market demands it. This gives you the best of both worlds.

Setting up your exchange account

Whichever exchange you choose, sign-up is straightforward. You'll need to provide ID verification (a requirement for all UK-regulated betting platforms) and deposit funds. Your exchange balance is separate from your bookmaker balance — you'll need money in both to place matched bets.

Once your account is set up, make sure you know where to find the lay betting option. On Smarkets, lay bets are highlighted in pink. On Betfair, they appear in the pink column on the right side of the odds display. Our getting started guide walks you through the entire setup process, including your first lay bet.

The bottom line

Both Smarkets and Betfair are reliable, well-regulated exchanges that work perfectly for matched betting. Start with Smarkets for its lower costs and simpler interface, and add Betfair later when you need the extra liquidity. What matters most is that you have at least one exchange account ready to go — without it, matched betting isn't possible.
