Smarkets review UK: prediction markets, exchange betting & legality explained

Let’s be honest about betting exchanges. Terms like prediction markets, commission and liquidity, don’t exactly sound simple. Add in questions about legality in the UK, and it’s easy to see why so many users get put off straight away.

It’s supposed to be fun, not an exam!

At its simplest, a betting exchange is just a platform where you bet against other people rather than a bookmaker. But the terminology can make it sound far more complicated than it actually is.

That confusion can lead to poor decisions. Some people pick the wrong platform, others misunderstand the risks, and plenty miss out on better odds without even realising it. So instead, they stick with a traditional bookmaker because it feels familiar.

But once you get your head around it, you realise it’s nowhere near as complicated as it sounds.

Platforms like Smarkets offer a different way to bet, often with better prices and more flexibility. Crucially, it’s fully UKGC-licensed, meaning it’s legal, regulated and held to strict UK standards. In this Smarkets review, we look at how the platform works, what it offers, and whether it’s a good fit for UK bettors.

Smarkets at a glance

So what is Smarkets? At its core, Smarkets is a UKGC-licensed betting exchange in the UK that lets users bet against each other rather than a traditional bookmaker like Ladbrokes or bet365.

That’s the key difference. Instead of the bookmaker setting the odds, prices are set by other users in the market, and you can even set your own price if there’s no match available, with Smarkets providing the platform and security for those bets to be matched.

Smarkets focuses mainly on sports betting – with football leading the way – but there’s also a solid range of markets covering politics, entertainment and major global events.

It’s best known for its competitive pricing and low fees, with a simple flat 2% commission on winning bets, and no fees at all if you lose. New users can also take advantage of a welcome offer: use code COMMFREE to get 0% commission on trades for 60 days.

Simply deposit £10 or more and enter the code during registration. Standard terms apply.

Smarkets in-depth review

Below, we take a deeper dive into Smarkets and break down some of the most important factors.

• License: UK Gambling Commission (UKGC) – 33562
• Year established: 2008
• Best bonus: 0% commission for 60 days
• Customer support: Email, live chat, X or post
• No. of markets available: Thousands across sports, politics and entertainment
• Casino: No
• Payment methods: Visa, Mastercard, Maestro, PayPal, Skrill, Neteller, Trustly, Instant Bank Transfer
• Withdrawal times: 12 hours to 5 business days, depending on method

Smarkets keeps things simple compared to other exchanges, with a clean interface and straightforward pricing. While some platforms charge variable commission, Smarkets sticks to a flat 2% fee, which is easy to understand, with nothing to pay if you lose.

Unlike traditional bookmakers, there’s no margin built into the odds, as prices are set by other users.

It can look complicated at first, with graphs and percentage figures across each market, but it quickly becomes straightforward once you get used to it. You’re betting against other users rather than a bookmaker – or what’s known as peer-to-peer betting – so prices are driven by supply and demand rather than being fixed.

The interface is clean and easy to navigate, with a search bar at the top and clear tabs to move between markets. Once you understand how backing and laying works, placing bets feels smooth, with the betslip showing exactly what you’ll win or how much you’re liable for.

Built-in tools like price graphs and the calculator help you track movements and plan your bets.

There’s also a “trade out” button, which is essentially the exchange version of cash out. It lets you lock in a profit or cut your losses instantly, with everything calculated in real time based on live prices.

Liquidity is strong on major markets like football, meaning bets are usually matched quickly at the listed odds. On smaller or niche markets, there may not be enough money available to match your bet straight away – for example, you might have to wait longer or accept a different price to get matched.

What is Smarkets best for?

Smarkets is best suited to bettors who want a straightforward exchange experience with competitive pricing.

Its commission model is the headline act in that regard. Those who make Smarkets their primary exchange don’t have to factor in fluctuating fees that can reach upwards of 5% in some cases – it’s a simple flat 2% commission on winnings across the board.

By comparison, some larger exchanges use more complex fee structures and may apply additional charges for highly profitable users, making Smarkets a more straightforward option – especially for experienced bettors, where small differences in fees can make a real impact over time.

That also makes it appealing for value betting, where small differences in odds and fees can impact long-term profit. Small savings on fees can add up over time – as the saying goes, look after the pennies and the pounds take care of themselves.

Pros

• Low 2% commission offers strong value
• Simple and easy-to-use platform
• Competitive odds on major markets

Cons

• Less liquidity on smaller or niche markets
• Limited bonuses and promotions after sign up

What is a betting exchange?

A betting exchange is a platform where you bet against other users rather than a bookmaker. This is known as peer-to-peer betting.

Think of it like betting with your mate. If you think England will beat Serbia and your friend disagrees, you’re taking opposite sides of the same bet.

That’s how an exchange works, just on a larger scale. You can either back (buy) an outcome if you think it will happen, or lay (sell) it if you think it won’t.

Traditional bookmakers build their margin into the odds, which means you’re often getting slightly worse prices without realising it. Betting exchanges work differently.

Because users set the odds, there’s no built-in margin in the same way. Instead, Smarkets charges a flat 2% commission on winnings, which can offer better value than other exchanges.

What are prediction markets?

Prediction markets are platforms where people trade on what they think will happen in real life.

Instead of just placing a bet, you’re buying and selling outcomes like they’re assets – similar to how you might buy or sell something like a house or a car. The price shows how likely something is to happen – for example, if something is priced at 70%, the market thinks there’s a 70% chance of it happening.

You might trade on things like who will win the Eurovision Song Contest or who will win the next UK general election.

Popular examples include Polymarket and Kalshi. These platforms focus on trading real-world outcomes and can get quite niche. For example, you might see markets on things like what price crude oil will hit by the end of the month, or even what MrBeast might say in a future video.

Are prediction markets legal in the UK?

Yes – Smarkets is legal and regulated in the UK.

In the UK, all betting activity is regulated by the UK Gambling Commission (UKGC). Operators must hold a licence to legally offer services to UK users.

Smarkets is UKGC-licensed, so it meets those requirements. You can check this on the UKGC register.

However, not all prediction markets follow the same rules. Many operate outside UK regulation and are not licensed for UK users.

That’s the key difference. While Smarkets is regulated, platforms like Polymarket and Kalshi are not, meaning UK users may not have the same level of protection. In some ways, it can feel a bit like the “wild west” compared to regulated operators.

Can UK users access Polymarket?

No. Polymarket is not regulated for UK users and is typically geo-blocked.

Some users may try to access it using a VPN, but this comes with risks. It goes against the platform’s terms, and could lead to account suspension or funds being locked.

As it’s not licensed by the UK Gambling Commission, you won’t have the same protections if anything goes wrong.

Smarkets vs prediction markets platforms

There’s a clear difference between the two.

Smarkets is a UKGC-regulated betting exchange that follows strict rules designed to protect users.

By contrast, platforms like Polymarket or Kalshi are crypto-based prediction markets that are not regulated for UK users. They can be more volatile and operate without the same level of oversight.

How Smarkets works

Below, we break down some of the key terms you’ll come across on Smarkets and what they mean.

Back (buy): This is the same as a traditional bet. You’re backing an outcome to happen – for example, backing a team to win. You choose your odds and stake, and your potential return is shown before placing the bet.

Lay (sell): This is the opposite. You’re betting against something happening – for example, betting that a team won’t win. If they lose or draw, you win. You’ll also see your liability, which is the amount you stand to lose if the bet doesn’t go your way.

Market trading: Prices on Smarkets move based on supply and demand. As more money comes in on one side, the odds shift. If there are no odds available, you can set your own price and wait for another user to match your bet.

In-play betting: You can also place bets while events are live. Odds update in real time, and there may be a short delay before bets are matched to keep things fair.

Smarkets also has a built-in “trade out” button, which lets you do this instantly. It calculates everything in real time based on live prices, allowing you to lock in profit, cut losses or cancel out a position with a single click.

Smarkets betting app

The Smarkets app is available on both Android and iOS, alongside a full desktop version.

It’s slightly more limited than the desktop version, with some features, like price graphs, removed, but you still get access to the same wide range of markets – over a thousand at the time of writing. There’s also a live stream option on selected events, marked by the “Play” icon.

Navigation is simple enough, with a useful search function accessible via the “Browse” tab at the bottom of the screen. As you’d expect from an exchange, live odds update quickly as the market moves.

Overall, it’s a solid app that covers the essentials, although it can feel a bit fiddly at times compared to the desktop experience

Smarkets fees and commission explained

No. Smarkets are pretty upfront with their commission fee, and proud of the fact they charge 2%, with no hidden fees.

That 2% is taken from your net winnings on a market, not every individual bet. If you lose overall, you don’t pay anything. There’s no bookmaker margin built into the odds, which is worth bearing in mind when comparing prices.

Available markets on Smarkets

Smarkets covers a wide range of markets, with sport making up the bulk of the action.

Football is the standout, but you’ll also find plenty of markets across horse racing, tennis, golf, boxing and cricket. Most major events are covered, along with a good level of detail within each market – for instance, cards, goals and player markets.

Outside of sport, there’s political and entertainment markets. That includes things like the next UK general election, next Prime Minister, or even who will be the next Chair of the Federal Reserve, alongside events like the Eurovision Song Contest.

Payment methods and withdrawals

Smarkets supports a solid range of payment methods for deposits and withdrawals. Here’s the breakdown.

How to get started with Smarkets

• Fill in your personal information, including your name, date of birth, address and phone number

• Complete KYC checks if required – this may involve uploading ID such as a passport, driving licence or national ID, along with a bank statement or utility bill

Once that’s done, you’re ready to deposit and start using the exchange.

Final verdict: is Smarkets worth it?

Smarkets is well worth your time. It doesn’t have to replace a traditional bookmaker entirely, but it works really well alongside one – especially when you’re looking to get the best possible value and profit on a market.

It offers tools you don’t typically get with traditional bookies, like price graphs that show how a market has moved over time. While some of the terminology can seem off-putting at first, it’s easy to pick up once you get started.

The range of markets is strong, with good depth across sports and events, and the flat 2% commission makes things more straightforward than other exchanges like Betfair Exchange or Matchbook.

It’s also reassuring to know it’s fully regulated by the UKGC, unlike unregulated platforms like Polymarket or Kalshi, so you have proper protection in place.

Liquidity can be lower on smaller or niche markets, which can make it harder to get bets matched quickly, but that’s where using it alongside a traditional bookmaker makes sense.
