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. That matches Betfair Exchange's standard rate, so on commission alone the two are level. The difference comes down to interface and liquidity, which we'll cover below.

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 Exchange commission rate is 2%, in line with Smarkets. The one nuance to be aware of is the Premium Charge: a small number of long-term winning customers get escalated to a higher rate once their lifetime profit crosses certain thresholds. For new matched bettors this is not a concern — you'll pay the headline 2% — but it's worth knowing about if you ever become a consistent high-volume winner.

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

Because both exchanges charge the same 2% standard commission on net winnings, the commission paid on any individual matched bet is effectively identical regardless of which exchange you use. The real decision is where you can get the best lay odds on the specific market you need — and whether there's enough money available to match your bet.

When using our matched betting calculator, enter 2% for whichever exchange you're using. 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 starting point. With commission a tie at 2%, the tiebreakers are the cleaner interface, the £1 minimum bet, and the fact that liquidity is perfectly adequate for the popular markets you'll be using during sign-up offers.

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 its cleaner UI but switching to Betfair when a specific market demands better odds or deeper liquidity. 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.
