Compare Betting Exchange Sites by Commission, Liquidity and Access
Four exchanges, four fee structures, and a Betfair rate that depends on the sport you back.

Compare the four betting exchanges before you pick one
Betfair, Betdaq, Smarkets and Matchbook each price things differently: a rate set by sport, a rate set by where you live, a rate set by how much you trade in a month. Not complicated, on paper. In practice, none of the four publishes one number you can trust across every market and country, and none of the four can be joined directly from this site, so there is no sign-up button below, only what each one states about itself. If you have not read how a betting exchange works, that is where back, lay, commission and liquidity get explained from scratch; this page assumes you already know the basics and goes straight to comparing the four operators. New to matched betting itself? Back and lay betting covers the hedging and break-even points the numbers below build on.
-
Betfair
Best for sport and racing liquidity Reachable via a broker
No sign-up link here: check the operator's own terms first.
Strength
- Publishes its Market Base Rate by sport, the only one of the four that documents its commission at this level of detail (officially stated, Australian help pages).
Weak point
- Adds an Expert Fee of up to 40 percent above a profit threshold for its most active winners, and country access has narrowed in several recent years.
-
Betdaq
Best for UK and Irish racing at a flat rate Reachable via a broker
No sign-up link here: check the operator's own terms first.
Strength
- States a flat 2 percent for UK, Irish, Gibraltar and Jersey residents, the lowest published headline rate of the four (officially stated, operator's home page).
Weak point
- Reviews consistently describe thinner liquidity than Betfair's and Smarkets' outside the biggest events, and the rate more than doubles to 5 percent everywhere else.
-
Smarkets
Best for a published rate with a worked example Reachable via a broker
No sign-up link here: check the operator's own terms first.
Strength
- Shows its 2 percent commission with an official worked example, and its UK licence is active and traceable on the Gambling Commission register.
Weak point
- Its treatment of winners is disputed: the operator has repeatedly denied closing accounts for winning, Trustpilot is dominated by locked accounts and slow verification, and the Gambling Commission fined Smarkets GBP 630,000 in August 2022 over anti-money-laundering failings.
-
Matchbook
Best for commission that only applies to a winning market Reachable via a broker
No sign-up link here: check the operator's own terms first.
Strength
- Its own educational blog states a Net Win Commission, charged on a market's profit and never on a losing bet, more clearly than any of the other three describe their own charge.
Weak point
- No official Matchbook page confirms its widely quoted 2 and 4 percent rates, and published sources describe a revenue-share clause reaching up to 60 percent of monthly profit above set thresholds, last documented in 2024 with its current status unconfirmed. Its UK licence was also suspended by the Gambling Commission from February to August 2020 over anti-money-laundering and social responsibility failings, reinstated after the operator addressed the Commission's findings.
Betdaq and Smarkets publish the lowest flat commission, Betfair publishes the most detail, and Matchbook's numbers are third-party estimates.
For UK or Irish residents, Betdaq and Smarkets both state 2 percent, beating Betfair's published Australian range on most sport markets. Outside those countries, run your own numbers before trusting a single headline: Betdaq rises to 5 percent, and Betfair has no non-Australian rate page to read. Matchbook's low-commission claim has never been confirmed on an official page, only in third-party tests, so treat it as a lead rather than a fact. Commission alone does not decide the best betting exchange for you. Liquidity does, and the table below scores both against the evidence behind each figure.
What Betfair, Betdaq, Smarkets and Matchbook actually charge
Every guide repeats "2 percent" or "5 percent" as if commission were one number. It rarely is: Betfair sets its Market Base Rate by sport and racing code, Smarkets scales by how much you trade, and Betdaq and Matchbook split by where you live. The table below breaks each one down, with the net odds a 2.00 shot becomes once the commission is taken out, and the evidence behind the figure.
| Exchange | Applies to | Rate | Net odds at 2.00 | Evidence |
|---|---|---|---|---|
| Betfair | Sport and international racing (Market Base Rate) | 6% | 1.94 | Officially stated (Australia only) |
| Betfair | Australian racing, by state and racing code | 8% or 10% | 1.92 or 1.90 | Officially stated (Australia only) |
| Betfair | NRL | 10% | 1.90 | Officially stated (Australia only) |
| Betfair | Expert Fee, profit over a rolling 52 weeks | 0% to 25,000 GBP, 20% to 100,000 GBP, 40% above | Not a per-bet rate | Sourced from Betfair's Australian help pages and a UK-focused guide; no direct UK Betfair page read |
| Betdaq | UK, Ireland, Gibraltar and Jersey residents | 2% | 1.98 | Officially stated (home page) |
| Betdaq | Residents of all other countries | 5% | 1.95 | Officially stated (home page) |
| Smarkets | Standard, net winnings per market | 2% | 1.98 | Officially stated (no date shown on the page) |
| Smarkets | Pro tier, high monthly volume | 1% | 1.99 | Reported; monthly thresholds not read on an official page |
| Smarkets | Select tier, net profit above 25,000 GBP in 12 months | 3% | 1.97 | Reported; thresholds not read on an official page |
| Matchbook | UK, Ireland, Channel Islands and Isle of Man | 2% | 1.98 | Reported by third-party tests only |
| Matchbook | Residents of all other countries | 4% | 1.96 | Reported by third-party tests only |
Net odds assume a single back bet at 2.00, using 1 + (odds - 1) x (1 - rate); a losing bet pays no commission on any of the four. Betfair's Expert Fee and Smarkets' Select tier are charged on profit over time, not on a single bet, so they carry no per-bet figure. Rates, tiers and thresholds change: read the live terms for your own country before you rely on any number here.
The part where 2 percent doesn't mean 2 percent
Every one of these four operators states a different rate depending on where you live, so start with the reminder before the round numbers: none of the figures below is "the" commission, only the one that applies to a resident of the countries each operator names. The rates picked here are the ones that apply outside the UK, Ireland and the handful of nearby territories that get the lowest headline, since most readers of a site about betting abroad are not sitting in one of those territories. Betfair is the exception: only its Australian rate is officially documented, and what it charges elsewhere is unconfirmed.
| Exchange | Rate used | Net profit | Total returned |
|---|---|---|---|
| Betfair | 6% (sport and international racing, Australia) | 94.00 | 194.00 |
| Betdaq | 5% (residents outside the UK, Ireland, Gibraltar and Jersey) | 95.00 | 195.00 |
| Smarkets | 2% (standard rate) | 98.00 | 198.00 |
| Matchbook | 4% (residents outside the UK, Ireland, the Channel Islands and the Isle of Man; third-party sourced) | 96.00 | 196.00 |
Stake and fair odds are invented for the example; the rates are read from each operator's own published figures (see the table above).
Smarkets returns 4.00 more than Betfair on this single winning bet, without you doing anything differently. Repeat it fifty times over a season and the gap between Smarkets and Betfair alone is 200.00, before either exchange's rate changes for your own country or your own volume.
UK, Irish, Gibraltar and Jersey residents see Betdaq's rate drop to 2 percent, and Matchbook states the same 2 percent for the UK, Ireland, the Channel Islands and the Isle of Man; neither Matchbook number has been read on an official Matchbook page, only in third-party tests.
The same arithmetic runs sport by sport, not just exchange by exchange: tennis prices compared across a retail book, a sharp book and an exchange works through one match at all three venue types, margin and commission both counted.
Why "reachable via a broker" isn't a fix
A broker account adds a login, not a right. If Betfair, Betdaq, Smarkets or Matchbook excludes the country you actually live in, a betting broker puts its own terms on top of that exclusion, not in place of it, and you become the broker's customer first.
Frequently asked questions
Which betting exchange has the lowest commission for my country?
Read the small print, not the homepage headline. Betdaq and Matchbook both quote their lowest rate, 2 percent, only for the UK, Ireland and a couple of nearby territories, then charge more everywhere else (5 percent and 4 percent). Smarkets states one flat 2 percent with no territory split found on an official page, and Betfair's only detailed rate table covers Australia. None of the four confirms a single worldwide number, so check your own country's terms before comparing headlines.
Which exchange has the best liquidity for my sport?
Betfair is the one reviewers consistently describe as the deepest, especially on major football and international racing. Betdaq and Smarkets are reported as noticeably thinner away from the biggest events, and Matchbook's tests describe solid depth on big football and racing markets with thinner books on niche ones. Open the market you actually want and read the amount waiting at your price; live liquidity cannot be measured and kept current on a page like this one.
Is Betfair available where I live, and what replaces it if not?
Betfair's own country list has never been readable, and third-party lists of accepted countries disagree with each other, so checking Betfair access for your own country is the only reliable step. If it excludes you, Betdaq, Smarkets and Matchbook each publish their own separate terms, and a broker's exchange access, covered on the broker hub, is a different route with its own rules, not a way around Betfair's.
Do betting exchanges charge winners more than casual bettors?
Based on Betfair's Australian help pages, yes for its biggest winners: an Expert Fee of 20 percent, then 40 percent, applies to a small share of accounts above stated profit thresholds, on top of the usual commission, though no UK Betfair page has been read to confirm the same terms apply there. Matchbook's terms have been quoted, in 2019 and again in 2024, as allowing a revenue share of up to 60 percent above its own volume and profit thresholds, though nobody has confirmed whether that clause is still active today. Betdaq's help pages are reported to reserve the right to apply different rates to certain high-volume or highly profitable customers, though this has not been read on an official page, so the evidence is thinner, not absent. Smarkets has no equivalent clause found in this research; it does raise its rate to 3 percent for its most profitable accounts, a milder version of the same idea.
What is the best Betfair alternative outside the UK and Ireland?
On commission alone, Smarkets' flat 2 percent is the simplest published number outside the territories that favour Betdaq. On principle, Matchbook's promise to charge only on a market's net profit is the cleanest idea, if you accept that its numbers are not officially confirmed. If none of the four fit your situation, a prediction market prices a similar bet through a different structure, and Polymarket is one place that structure actually works today.
Can these exchanges be reached through a broker from abroad?
Yes, according to the brokers themselves, though none of the four operators confirms it on their own pages. A broker adds its own account, fees and identity checks on top of whatever rules the exchange already has for your country, covered in full on the broker hub. It is one more layer, not a shortcut past the exchange's own terms.
