A sharp bookmaker makes its own prices, keeps its margin low and takes big bets from well-informed punters, using their money to sharpen the price. A soft bookmaker follows prices made elsewhere, adds a bigger margin and limits customers who keep beating it, because its profit comes from customers who bet without an edge.
The two words come from overseas betting, and most bookmakers sit somewhere between them. In Australia the practical question is which price to trust as the reference: usually the Betfair exchange close to the start, or the margin-free price across many bookmakers.
Sharp and soft: what the two words mean
The words describe how a bookmaker builds its prices and who it is built for. The sharp end is also called a market maker, because others take their prices from it; the soft end is called recreational, because it is built for punters betting for fun. The same words describe punters: a sharp punter's bets tend to beat the closing price, and sharp money is money the market treats as well informed.
| Market maker (sharp) | Recreational bookmaker (soft) | |
|---|---|---|
| Where prices come from | Its own compiling, sharpened by the bets it takes | A reference market, plus its own margin |
| Margin | Low | Higher |
| Stake limits | High, and its main control on risk | Lower, often set account by account |
| Informed money | Taken at a price, because it shows where the true chance sits | A cost, because it takes prices before they move |
| How it competes | On price | On products, markets and promotions |
| What a winning customer meets | Higher limits than elsewhere, but still limits | Smaller stakes, fewer promotions or a closed account |
It is a spectrum, not two boxes: one bookmaker can make the price on the markets it knows best and follow on everything else. On an exchange, a market maker is a trader who keeps offers on both sides.
One game, priced by a maker and a follower
With illustrative prices on a two-team game:
| Team A | Team B | Market: sum of 1 / price | |
|---|---|---|---|
| Market maker | $1.94 | $1.98 | 102.05% |
| Follower | $1.85 | $1.90 | 106.69% |
| Fair price from the maker's market | $1.98 | $2.02 | 100% |
The fair prices scale the maker's implied chances down to 100%: Team A = (1 / 1.94) / 1.0205 = 50.51%, a fair price of 1 / 0.5051 = $1.98, and Team B = 49.49%, or $2.02. At the maker either side returns 1 / 1.0205 = 98.0 cents per dollar on average. At the follower, Team A returns 0.5051 x 1.85 = 93.4 cents and Team B 0.4949 x 1.90 = 94.0 cents.
Then news breaks for Team A and the maker moves first, to $1.70 and $2.25 (103.27%). Team A's new fair price is 1.70 x 1.0327 = 1.7556, about $1.76. For a few minutes the follower still shows $1.85, an edge of 1.85 / 1.7556 - 1 = 5.4% against that fair price, until it moves to $1.66 and $2.15.
That 5.4% exists only while the follower lags: it is the gap a punter watching the leading market can take, and money the follower gives away on every bet struck at its old price.
Risk: Betting involves risk. A lagging price can be cut before your bet is accepted, a fair price taken from another market is an estimate, and a +EV bet can still lose, and often does. See responsible gambling for limits and support.
Australian corporate bookmakers: mostly followers, sometimes leaders
Australian corporate bookmakers, the online and phone bookmakers run as companies, mostly sit at the follower end. Their business is the right-hand column of the table: margin earned from customers betting at their prices without an edge, competition through products, markets and promotions, and stake limits as the defence against informed money.
Following suits that model, and Australian racing offers references to follow: the exchange, with no margin built into its prices, and in NSW an official price built from the big operators. Since May 2017 those operators' prices, corporate bookmakers among them, have fed the NSW Official Price (checked October 2026).
That cuts both ways: a move can start in those operators' prices and reach the exchange afterwards, so who leads changes from market to market. How bookmakers set odds covers the compiling side.
The exchange as the Australian price reference
On ACMA's register, Betfair Pty Ltd, which runs the Betfair exchange, lists the Northern Territory's wagering regulator as its licensing authority (checked 6 October 2026). On an exchange, punters back and lay against each other and the exchange takes commission from net winnings in a market, so the prices carry no bookmaker margin. That is why exchange prices are the usual local reference, within limits:
- Its prices are only as sharp as the money traded on them: a busy race near the jump usually leaves a narrow gap between back and lay, while an early or small market can leave one too wide to read.
- Commission changes what a winning bet pays, not the chance, so compare chances, not payouts.
- Some sports markets trade little on the exchange, so for sport the usual reference is the margin-free price across many bookmakers, with the exchange added where it trades.
Betfair true odds works through the midpoint, commission and liquidity with numbers.
Why an offshore bookmaker is never the benchmark
Overseas guides often name an offshore bookmaker as the sharp price to measure against. Do not use one. Offering online betting to people in Australia without a licence from an Australian state or territory is an offence under the Interactive Gambling Act (s 15AA), and advertising such a service is banned, websites included (s 61EA). ACMA asks internet providers to block illegal gambling sites, and warns that an illegal operator may not pay out winnings, may close or move and take customers' money with it, and that Australian regulators cannot help its customers.
There is a practical problem too: a price you cannot lawfully be offered gives you nothing to bet at, and chasing it leads to an account without the protections Australian providers must give, such as deposit limits and BetStop. Use the exchange near the start and the margin-free price across Australian bookmakers instead. Offshore betting sites sets out the law and the risks.
Limits and restrictions are part of the follower model
A follower's margin works only while the customers taking its old prices stay few. On the example above, 200 bets of $100 at its lagging price, each worth 5.4% to the punter, cost it about 200 x $100 x 0.054 = $1,080 on average. The same $20,000 from customers betting at its usual 106.69% prices earns it about 1 - 1 / 1.0669 = 6.3 cents a dollar, roughly $1,250. So it limits the first kind of customer and courts the second, through:
- a lower maximum stake for that account than for others, sometimes called stake factoring
- promotions withdrawn from the account
- bets voided in the cases its terms set out, or the account closed
Bookmaker terms generally allow all three, and the NT Wagering Commission, which licenses many of the big online bookmakers, says it cannot investigate account restrictions, including limits on how much a customer can bet (checked October 2026). Racing is the partial exception. Some racing bodies set minimum bet limits on eligible fixed-odds racing bets. Under Racing NSW's Schedule 1, NSW-licensed bookmakers authorised for telephone and electronic betting must not refuse, close or restrict an account to avoid the limits they are bound by (checked October 2026).
Why bookmakers restrict accounts covers the triggers and complaint routes. A limit is not something to get around with another account or someone else's identity.
What the split means when you bet
Three working rules follow, each part of a wider betting strategy:
- Judge a price against the sharpest reference you can see, then take it wherever it is highest: the reference values the bet, and a follower may offer the price.
- Treat a follower's price far above the reference as a lag or a mistake: it may be cut before your bet lands, or voided under the bookmaker's terms as an obvious error.
- Record the price you took and the close. If your bets keep beating the close at follower bookmakers, expect smaller stakes there in time.
| Mistake | Why it misleads |
|---|---|
| Calling a bookmaker soft because one runner is long | It may be shading other runners, or simply slow on that one |
| Using an offshore price as the benchmark | You cannot lawfully be offered it, and chasing it leads to an unprotected account |
| Thinking soft means beatable | A follower's margin is bigger, so most of its prices sit further below fair, not closer |
Risk: Betting involves risk. Beating a follower's lagging price is no guarantee of profit, a bookmaker can restrict an account that keeps doing it, and past results are no guarantee of future results. See responsible gambling for limits and support.
Comparing bookmakers with the exchange on B337's Terminal
B337's Terminal lines up prices from 40+ bookmakers across racing and sports in their own columns beside Betfair back and lay, with flucs and closing lines. Price history shows how each price has moved, so you can tell a firming price from a drifting one, and you can see where each bookmaker sits against the exchange. Its EV overlays show the expected value of each price against an estimated fair price. That is an estimate, not a forecast, and a bet priced above it can still lose.
Prices are read on a repeating cycle, so a lagging price on screen may already have moved at the bookmaker: confirm it there before you bet. A free account opens a limited view of the Terminal with live odds. Betfair is a trade mark of its owner, and B337 is not affiliated with it. Bookmaker names are trade marks of their owners. B337 is not affiliated with them.

Risk: Betting involves risk. A price that looks out of line may be gone by the time you bet, and bookmakers can limit stakes, void bets or close accounts under their terms. See responsible gambling for limits and support.
