Betfair Exchange is a peer-to-peer betting marketplace. You're not betting against Betfair — you're betting against other users. One person backs (bets it will happen), another person lays (bets it won't happen). Betfair matches the two sides and takes a small commission from the winner.
Traditional bookmakers set the odds themselves and profit from the margin built in. On the Exchange, odds are set by the market — supply and demand. This usually means significantly better prices, especially on favourites. You also get the ability to lay outcomes, which bookmakers don't allow.
For traders specifically, the Exchange is the only legal, liquid market where you can back and lay the same selection to profit from price movement — without caring about the actual result.
Betfair charges commission on your net winnings in each market you trade. Standard rates: 2% on horse racing (UK/Ireland), 5% on most other sports. These rates vary by country — some markets have different base rates.
Commission at 5% = £7.50. Net profit = £142.50.
If Arsenal loses, you lose your £100 stake. No commission on losing bets.
Commission only applies to net winnings in a market, not gross turnover. If you make 10 trades in one horse race and end up with a £20 net profit, you pay commission on the £20, not on the total staked across all trades.
Your effective rate decreases as your lifetime volume increases through Betfair's loyalty programme (called the Market Base Rate reduction). See our full commission guide for the full tier breakdown.
Yes. Betfair is licensed and regulated in the UK by the Gambling Commission (licence 39563), in Ireland by the Revenue Commissioners, and in Australia by state and territory regulators. It's one of the most regulated gambling operators in the world.
Betfair is available in dozens of countries. Some countries restrict or block access to Betfair — check your local regulations and Betfair's country list at account registration. Using a VPN to access Betfair from a restricted country violates their terms and can result in account closure and withheld funds.
Backing means betting that something will happen. You back Manchester United to win. If they win, you profit. Same as a standard bet.
Laying means betting that something will NOT happen. You lay Manchester United to win — effectively acting as the bookmaker for anyone who wants to back them. If United don't win (draw or loss), you keep the backer's stake. If United do win, you pay out their winnings.
If United do NOT win: you collect the backer's stake = £50 profit (minus commission).
If United win: you pay out (2.00 − 1) × backer's stake. At 2.00 odds, your liability = £50.
The key lay concept to grasp: your liability (maximum loss) when laying equals (odds − 1) × stake. At odds of 5.0 with a £10 lay stake, your liability is £40. See our full lay betting guide.
The minimum bet is £2 (or equivalent local currency) on most markets. Some specialist markets have higher minimums. There is no Betfair-imposed maximum — your effective maximum is limited only by available liquidity on the other side of the market.
UK horse racing markets typically have £500K–£5 million matched per race. Premier League football Match Odds can exceed £10 million in-play. Grand Slam tennis finals regularly match several million. Low-volume markets (League Two football, minor tennis) may have under £50,000 — fine for small stakes but not for professional trading sizes.
Trading on Betfair means taking both sides of a market — backing AND laying the same selection — to profit from the movement in odds, regardless of the actual result.
Ten minutes later the price drops to 3.40 (lay at 3.40 with adjusted stake).
Result: £18.25 profit on the trade, regardless of whether the horse wins or loses.
You're not relying on the race result — you profited from the odds movement.
This is conceptually identical to buying low and selling high on a stock market — except you can also "sell short" (lay first, then back lower) if you think a price will drift out. See our full trading introduction.
Greening up means spreading a profit equally across all outcomes in a market, so you make a guaranteed amount regardless of the result. On Betfair's interface, positive P&L shows green — hence the term.
After a successful trade, your profit sits on one selection but you have zero (or negative) on the others. Greening up redistributes that profit by placing hedge bets on the other selections. You can do this manually using the hedging calculator, or automatically using the "cash out" or "hedge" buttons in trading software.
Once greened up, the race result is irrelevant — you've locked in your profit. See our green up guide for the full process.
Yes — but it's genuinely difficult and most beginners lose money in the early stages. Here's an honest assessment:
Who makes money: Traders with fast execution (via software), a specific edge or strategy, strict bankroll management, and the discipline to cut losing trades immediately. Many full-time professional traders operate profitably on UK horse racing and Premier League football markets.
Who doesn't: People who guess direction without a strategy, trade illiquid markets, hold losing positions hoping for recovery, or don't account for commission in their P&L calculations.
Realistic timeline: Expect 6–12 months of learning before consistent profitability, even with significant effort. Start with small stakes — £2–£5 per trade — and treat early losses as the cost of education. See bankroll management before you start.
Start with UK horse racing Win markets — specifically races with 5–8 runners (not too complex) and at least £300,000 already matched pre-race. Good liquidity means your orders get matched quickly and you can exit positions cleanly.
Avoid in-play trading until you understand pre-race markets. Avoid football unless you're specifically studying the Lay the Draw strategy. Avoid low-liquidity markets — if a market has under £50,000 matched, your orders will move the price and exits will be difficult.
The standard beginner path: pre-race horse racing scalping → swing trading → in-play → other sports. Each stage builds on the previous.
Scalping means taking very small profits from tiny price movements, very quickly and very frequently. A scalper might aim for 1–2 ticks of profit per trade (a tick is the minimum price increment on the exchange ladder). At odds of 3.00, one tick is the difference between 3.00 and 3.05.
Profit: approximately £0.88 before commission.
Do this 20 times per race across 10 races and commissions eat everything.
Pure scalping requires software, fast reflexes, and very tight discipline. The margins are thin — commission at 5% destroys profitability if your win rate isn't high. Most beginners find swing trading easier to learn first. See our scalping guide.
For casual, occasional bets — no. The Betfair website works. For active trading, especially pre-race scalping or in-play trading — yes, software is essential.
The standard Betfair website has a 1-second price refresh delay, no true one-click betting, no trading ladder view, and limited P&L tracking. At any reasonable trading frequency, those limitations cost you money in execution delays and missed exits.
Third-party software gives you: instant price refresh (typically under 200ms via the API), a proper trading ladder for one-click back and lay, automated green-up, and tools to track P&L across sessions. See our software ranking.
Yes. Bet Angel has a free basic tier. Geeks Toy (via some promotions) and Cymatic Trader are free to use with a funded Betfair account meeting certain criteria. These free tiers have limitations — mainly fewer markets open simultaneously and some automation features locked.
The free Bet Angel basic version is genuinely usable for learning. Most serious traders move to a paid subscription within a few months as their trading volume grows. See our free software guide for all free options compared.
The Betfair API is a programming interface that lets software applications connect to Betfair's market data and place bets programmatically. It's what all third-party trading software (Bet Angel, Geeks Toy, etc.) uses under the hood to get faster price data and one-click execution.
You don't need to use the API yourself — just using software that connects via the API is sufficient. You only need to interact with the API directly if you're building automated trading bots or custom tools. See our API guide for developers.
The Premium Charge is an additional levy on highly profitable customers who are generating very high profits relative to their commission payments. It affects fewer than 0.1% of active users — almost exclusively full-time professional traders with exceptional, consistent win rates.
If your lifetime net winnings exceed a threshold AND your commission paid represents less than 20% of your gross profits, Betfair levies up to 60% on your profits for that week. The thresholds are high. If you're wondering whether it applies to you, it almost certainly doesn't yet.
See our Premium Charge guide for the exact thresholds and how traders manage it.
This is far less of a concern on the Exchange than with traditional bookmakers. Betfair's revenue comes from commission on every winning bet — they profit from volume, not from punters losing. Consistent winners generate consistent commission, so Betfair has no financial reason to restrict them.
Account restrictions are typically for: violating API terms with aggressive bots, multi-accounting, bonus abuse on their sportsbook (not the Exchange), or suspicious activity. Pure exchange traders who win consistently and operate within the terms are very rarely restricted.
The Premium Charge is how Betfair manages its exposure to highly profitable traders — it's essentially a tiered commission increase rather than an account restriction.
The process takes about 10 minutes. You need: a valid email address, proof of age (passport or driving licence), and a deposit method. Betfair requires identity verification before you can withdraw — upload your ID during registration to avoid delays later.
Start with a small deposit — £50–£100 is enough to learn with. Don't load your full trading bankroll until you've spent a few sessions understanding how the exchange works. See our full account opening guide for step-by-step instructions, or open your account here.
Betfair Starting Price is a computer-generated price calculated at the moment a race starts, by matching all remaining unmatched back and lay bets at the turn-in-play point. It's useful when you want to back or lay a horse at a fair market price without being at your screen at race time.
BSP is generally close to the final pre-race price but not identical — it can differ significantly for unpopular selections with thin liquidity. BSP bets are not available in all markets. They're commonly used by automated systems and matched bettors who don't want to manually manage race timing. See our BSP guide for full details.
