Smarkets Review 2026: Is the Low-Commission UK Exchange Worth It?
Smarkets is a UK-regulated betting exchange that prices events like a prediction market. With 2% commission on net winnings (about half the rate of most UK exchanges), strong political and sports coverage, and a clean mobile app, it is the top pick for UK traders who want prediction-market-style exposure without going crypto-native.

The 30-second verdict. Smarkets is the best option for UK and EU traders who want prediction-market-style pricing inside a fully regulated betting exchange. The 2% commission is roughly half the rate of Betfair, liquidity is solid on flagship political and sports markets, and the UK Gambling Commission license offers strong consumer protection. Not available to US residents. For US traders, use Kalshi instead.

What is Smarkets?
Smarkets is a UK-based betting exchange launched in 2010. Unlike traditional bookmakers, it does not set odds itself. Users back (bet yes) and lay (bet no) against each other at peer-to-peer prices, just like a prediction market. The exchange takes a 2% commission on net winnings per market.
Smarkets is fully regulated by the UK Gambling Commission and holds a Malta Gaming Authority license for EU coverage. User funds are held in segregated accounts, and the platform is subject to UK consumer protection rules, including the GamStop self-exclusion scheme and mandatory affordability checks.
Markets and coverage
Smarkets is strongest in two categories:
- Politics: UK general elections, party leader races, Scottish politics, US presidential elections, French and German elections, EU votes, and more
- Sports: Premier League, Champions League, international football, Grand Slam tennis, Formula 1, horse racing, NFL, NBA
Flagship political markets (UK general election, US presidential) regularly trade £1M+ per day with tight bid-ask spreads. Sports liquidity is particularly deep on Premier League and major horse racing events.
Smarkets does not list crypto, weather, economic, or cultural markets. For that breadth, use Polymarket.
Commission structure
Smarkets charges a flat 2% commission on net winnings per market. There are no maker rebates and no tiered structure, which makes the pricing easy to reason about. If you win £100 net on a market, Smarkets keeps £2 and you keep £98.
That 2% rate is the key differentiator. Betfair, the larger UK exchange, charges 5% (with tiered reductions for high-volume traders). For most users, Smarkets’s flat rate is cheaper.
There are no deposit or withdrawal fees, no inactivity fees, and no subscription tiers.
Smarkets vs Polymarket: which should you use?
Different tools for different users:
- Regulation: Smarkets is UK-regulated with full consumer protection. Polymarket is on-chain with self-custody and no regulatory backstop.
- Payment: Smarkets uses GBP via standard UK bank rails. Polymarket uses USDC on Polygon.
- Market breadth: Polymarket wins by a wide margin, especially on crypto, geopolitics, and cultural markets.
- Liquidity: Smarkets is deeper on UK politics and European sports; Polymarket is deeper on US and global crypto markets.
- Friction: Smarkets is simpler to set up for UK users. Polymarket requires wallet setup.
If you are in the UK and mostly trade UK politics or European sports, Smarkets is the default. For global markets or crypto exposure, use Polymarket.
