Ante-post betting is the part of horse-racing markets that sits weeks or months before a race, while the runners still walk around their fields and the form book is mostly guesswork. The prices are bigger than on the day. The price for that bigger number is that the bet does not behave the way every other bet a punter places does: a horse that does not run is a loss, not a void, and the bookmaker’s margin sits inside every quote all the same. This page sets out what ante-post really costs the backer in 2026 — the rules that govern it, the arithmetic behind a price, the bookmakers who hold a Gambling Commission licence to offer it, and the safer-gambling protections that come with betting through any of them. Data was verified on 27 October 2026 against the register the Gambling Commission keeps.

Staying in control while the markets are still open

The first thing a punter pays in ante-post betting is not in pounds. It is the cost of chasing a future race across weeks of form lines, market moves and trainer bulletins — and that is the kind of slow-grind product that financial vulnerability checks, self-exclusion and stake discipline exist to police. Any licensed bookmaker in Great Britain must offer GAMSTOP self-exclusion (six months, a year, five years or five years with auto-renewal, after which the exclusion runs on for a further seven years unless the customer asks for it back), must run a public-record check on the customer once their net deposits in any rolling 30 days cross £150, and must offer a gross deposit limit on a fixed time frame. The bookmakers reviewed below — Fitzdares, Tote, Geoff Banks, Lottoland, Betmaster, 10bet, bet365, Copybet, London Bet and BetMGM — are all Commission-licensed, and the bonus terms the regulator introduced from 19 January 2026 cap wagering requirements at 10x (a £10 bonus with a 50x turnover, which would need £500 of bets to clear, is no longer allowed). Punters can dial their own deposit ceiling down to whatever they want; the regulator does not set one. Identity is checked before the first deposit, so there is no anonymous ante-post play at a licensed site.

Help exists outside the operators: GamCare runs the National Gambling Helpline, GambleAware funds treatment and education, NHS gambling clinics run in several regions, and Gamblers Anonymous runs meetings. The Commission’s own duty is licensing and enforcement; GamCare’s is support. Ante-post is a market that punter has time to think about, and that time is the reason the safer-gambling regime leans in on it.

Tips, predictions and the strategist’s reading of the form

Search for ante-post tips and the answers split into two camps: the tipster with a published record, and the punter running their own analysis from sectional times, going reports and trainer patterns. Both face the same starting condition — futures are priced longer than on-the-day markets and the favourite has not been beaten by anything yet. The tipster’s value is converting a long morning’s reading into one name with a price attached; the analyst’s is the same job done in-house with the punter’s own eye. Neither beats the market simply by being right more often. The market has already priced in the consensus view of every analyst feeding it, so beating it means reaching a different conclusion from that consensus at the right price. The handful of tipsters worth listening to publish a year-on-year record and make the basis of that record readable; the rest is marketing.

What a punter can do alone is the cheaper part of the trade. Racing databases give sectional times and going reports weeks ahead; trainer and jockey patterns are public; weight-for-age comparisons can be done by hand. The cost of doing it well is time and discipline: write down the price at the moment of the bet, write down the result at the moment of settlement, and let the record speak for itself over a season or two. A tipster subscription will not cover a punter who does not keep records, and a model will not cover one who does not understand its assumptions. The arithmetic the page runs through below — payout share, margin, what a free bet is really worth — is the same arithmetic that decides whether any of it is paying the punter back.

Selection, staking, settling — how the bet moves through the day

Ante-post bets in Great Britain are settled at the price available when the bet was placed — not the starting price, not a best-odds-guaranteed revision. A backer who took a horse at 20/1 in October will be paid at 20/1 if it wins in March; the movement of the price between the two dates is somebody else’s trade, not the punter’s. The same rule means Best Odds Guaranteed, which kicks in on UK and Irish racing from 8 AM on the day of the race, does not apply to ante-post — Tote and William Hill state this explicitly. Forecast bets, place-only bets and conditional bets are not accepted on ante-post in the standard offering; the markets the bookmaker accepts are win and each-way singles, plus accumulators.

Each-way terms vary by bookmaker, by race type and by the number of runners declared. A non-runner in an ante-post each-way still costs the punter both halves of the bet. Where an ante-post selection is balloted out or eliminated from an accumulator, the bet continues to run on the remaining legs at their original prices — a treble becomes a double, a double becomes a single. The price each leg was taken at does not move. That single rule lets a punter who likes long-term futures bet an accumulator without losing the whole stake the moment one fancied runner drops out, but the price on the remaining legs was set in colder weather and on thinner form, so what it really does is postpone the decision rather than fix it. A single ante-post bet on a runner that drops out is simply void; the stake returns.

Rule 4 deductions apply when a runner is withdrawn from a race and the bookmaker takes a fraction of the remaining runners’ winnings to compensate. The rule lives in section 7 of the page below.

How the bet is built, placed and settled

The walkthrough is the same as for any fixed-odds bet on the licensed market, with three extras the ante-post product carries. Open an account with a bookmaker the Gambling Commission register lists, verify name, address and date of birth before the first deposit, set a deposit limit, find the future-racing market under “horse racing” then “future” or “ante-post”, pick a selection at the price displayed, place the bet. The price shown is the price paid. Stake decides the return; the formula the page uses is the standard one for decimal and fractional odds, both of which the page labels as it uses them. The Commission requires each licensed remote bookmaker to run a public-record vulnerability check once net deposits exceed £150 in any rolling 30 days, and the same bookmaker must honour a GAMSTOP self-exclusion against anyone registered on the scheme — both of which kick in for ante-post punters the same as for any other market.

Settlement runs on the result the official judge declares. If the race is abandoned or moved to a different track, ante-post bets are void and the stake is returned. If the horse does not run, the ante-post bet loses — the single biggest difference between ante-post and on-the-day markets, where a non-runner usually makes the bet void with the stake returned. The distinction is the heart of the product and the reason a long-priced bet is longer than its on-the-day equivalent: the punter is carrying the non-runner risk that the day-of-race market does not have to.

Rule 4 and the price of a withdrawal

Rule 4 sits inside every fixed-odds horse-racing bet, ante-post or otherwise. When a runner is withdrawn from a race, the bookmaker applies a deduction to the winnings of every remaining runner whose odds are longer than the withdrawn horse’s odds, scaling from about 30p in the pound for the shortest-priced withdrawals down to about 5p for the longer-priced ones. The deduction is deducted from the gross return, not from the stake, and a horse at the favourite’s price or shorter is usually unaffected because the market has already moved to absorb the withdrawal. The rule exists because the odds were struck on a field that no longer exists, and the deduction returns those odds to something closer to the new market.

What this costs the punter depends on the structure of the bet. On a single ante-post bet at long odds, a Rule 4 of 25p in the pound at settlement takes 25% off the winnings — a £10 bet at 20/1 that would have returned £210 pays £160 instead. On an accumulator, every leg faces its own possible Rule 4, and the deductions compound across the bet. Ante-post punters do not face Rule 4 on the day the bet is placed, because the bet is on a future race; the rule applies only at settlement, against whatever the field has become by then. A punter who likes a horse at 25/1 in November and the horse is still in the race in March will not see Rule 4; a punter whose second-favourite is withdrawn the week before the race will.

The ten operators offering ante-post in Great Britain

Ten bookmakers hold a Gambling Commission remote licence for the category “remote general betting standard (real events)” and offer ante-post markets on horse racing. Each is reviewed below on its licence, its ante-post terms and the practical implications of betting through it. None of the ten sits ahead of the others on the same axis; each carries a different mix of price, depth and product.

Fitzdares — premium positioning, ante-post inside it

Fitzdares runs on a Gambling Commission remote licence under account 400, in the name of Fitzdares Limited. The mobile product bundles horse racing, football, tennis, rugby, cricket, golf and American football, with ante-post markets on each; in-play live odds sit alongside; accumulators, Lucky 15s, specials and cash out are advertised on the App Store listing. The brand positions itself as a premium layer over a standard bookmaker, and the ante-post offering sits inside that positioning — priced deeper than the high-street chains on the more popular races, with a thinner card on the second-tier meetings. Punters who like a focused ante-post card and the price advantage on headliners will get what they want here; those looking for a deep card across every meeting in the calendar will hit gaps.

The verdict, then, is for the ante-post backer who wants premium pricing on the major meetings and does not need every race in Britain covered. A smaller card on the second-tier events is the trade-off, and the rest of the sportsbook is wide enough that the brand works as the punter’s main account rather than as a one-market secondary bookie.

Tote — pool-betting roots, fixed-odds ante-post alongside

Tote.co.uk is the GB-licensed online home of the Tote, run by TDCO Limited under Commission account 54779. Ante-post fixed-odds markets are on the menu, but the brand’s distinctiveness is its pool product, which sits across horse racing and a few other categories. BOG kicks in from 8 AM on the day of the race — the same rule William Hill publishes — and does not extend to ante-post bets. What Tote adds is a settled approach to a horse race: the pool product pays a dividend rather than a fixed-odds return, so the price reflects the entire field’s stake rather than the bookmaker’s line on the favourite. A punter who wants that pricing dynamic next to a fixed-odds ante-post card has a one-stop shop here.

The verdict sits with the punter who wants pool-betting pricing on the day of the race and a respectable ante-post menu ahead of it. Tote is not the deepest ante-post bookmaker in Britain on the second-tier meetings; it is one of the few operators where the punter can split their action between pool and fixed-odds from the same wallet.

Geoff Banks — independent bookmaker with a focused card

Geoff Banks’ online product is published by GB Sports Advisors Limited under Commission account 54095. The mobile app carries live in-play prices on current events and ante-post prices on futures. The brand is small in market share and large on hand-built customer service; the ante-post card is built around the meetings the firm’s traders care about rather than the meeting every other firm offers. A punter looking for a bookmaker who will price a horse from a smaller yard because the form-reader in the trading room has noticed something will find that bookmaker here; a punter wanting the depth of bet365 on a midweek all-weather card will not.

The verdict lands on a bettor who values an independent bookmaker’s eye on ante-post over a bigger brand’s wide card. The drawback — fewer markets, especially on the second-tier meetings — is the price of being independent, and a punt for whom depth matters more than judgement will get more from a wider bookmaker.

Lottoland — lottery-led, ante-post in the portfolio

Lottoland.co.uk is operated by EU Lotto Limited under Commission account 38991; the app combines casino, lottery betting, scratchcards and sports betting. The brand’s centre of gravity is the lottery products, and horse-racing ante-post is one of several verticals a user might wander into while on the site. The Commission’s GB licence covers the brand for everything it sells to British customers, and the ante-post offering is straightforward — markets on the major meetings, in-play on the day of the race — without the depth of a dedicated sportsbook. Lottoland works best as a one-account-fits-all-verticals brand for a bettor whose main interest is the lottery product and whose ante-post interest is occasional.

The verdict is for a punter whose main bet is the lottery and who wants a place to put the occasional ante-post bet through the same wallet. Anyone whose main interest is horse racing will do better with a dedicated sportsbook.

Betmaster — Maltese-run, GB-licensed for the customer

Betmaster.co.uk is run by BM Solutions GB Ltd, registered in Malta, under Commission account 65699. The structure is familiar from the wider industry: a remote sportsbook licensed in Malta for the trading operation, with a GB licence for the customer relationship. The ante-post offering is inside a sportsbook that also runs casino and live-dealer products; the horse-racing section is the centre of the ante-post card, with markets on the major meetings and a limited card on the minor ones. The Malta-registered owner has no negative read in the Commission’s register; what it has is a structure that puts a Maltese holding company above the GB-licensed vehicle, which means the dispute route for a British customer still runs through the Commission rather than through a Maltese regulator.

The verdict lands on a punter who is comfortable with the Maltese-owner-over-GB-licence structure and wants a sportsbook depth typical of mid-tier international brands. The ante-post card is honest rather than deep, and punters who want the widest card in Britain should look at the bigger brands.

10bet — sportsbook standard, ante-post inside the racing section

10bet.co.uk runs under Commission account 43173, in the licence of Blue Star Planet Limited; the mobile app covers football, tennis and horse racing, with cash out, a bet builder and live streaming advertised on the App Store listing. Ante-post on horse racing sits inside the racing section in the standard way. 10bet has a long history as a sportsbook — the brand dates back to the early online era — and the GB operation is the UK face of an international bookmaker. The ante-post menu is built around the meetings traders expect to take money on, with a thinner card on the second-tier events. A punter who wants cash out, a bet builder and live streaming alongside an ante-post menu has all three here.

The verdict is for the punter who wants a sportsbook depth on football and tennis as well, and will take the ante-post card as part of a wider package. A punter whose primary interest is horse racing will be better served by brands with a racing-first ante-post card.

bet365 — the reference depth every other brand is built against

bet365 is run in Great Britain by Hillside (UK Sports) ENC under Commission account 55148. The mobile product is the most-downloaded betting app in Britain and the reference card the rest of the online market measures itself against. Ante-post horse racing is one section in a product that also runs Bet Builder+ (combining markets from one event into a single bet, both pre-match and in-play), Super Boosts, winnings boosts on bet builders and selected singles, and daily bet boosts. The ante-post card on a busy week runs to several pages per meeting, and is the closest thing the British online market has to a complete listing. A punter who wants the deepest ante-post menu in Britain, a bet builder that crosses markets within one event, and the in-play product that goes with it, has that here. The drawback is the brand’s market position: the same depth is available in every account, and the price advantage that an independent bookmaker can offer on a single name rarely reaches bet365’s menu.

The verdict goes to the punter who wants depth over price advantage — and that is most online punters in Britain. Anyone whose strategy is to back one or two outsiders a week on a smaller meeting is paying for depth they do not use; anyone whose card spans several meetings and several sports a week is using it.

Copybet — all-day BOG and first-past-the-post settlement

Copybet runs under Commission account 53774 in the name of Copybet UK Limited. The brand’s two distinctive rules on horse racing — Best Odds Guaranteed all day, every day on UK and Irish racing, and first-past-the-post payouts even if the winner is later disqualified — are both worth reading closely. All-day BOG covers day-of-race bets and does not extend to ante-post, as the brand’s own terms state. First-past-the-post is a settlement rule that matters when a horse crosses the line first and is then demoted by the stewards — the punter is paid on the result the judge declared at the line. Ante-post markets sit inside a sportsbook that runs specials, accumulators and a copy-trading product.

The verdict lands on a punter who values first-past-the-post settlement on the day of the race and wants an all-day BOG on day-of-race bets. Ante-post punters do not benefit from either rule because the bets settle at the price taken, and the relevant fact is that the ante-post card is solid without being the deepest on the market.

London Bet — app-first, ante-post on a small sportsbook

London Bet is run by Thistle Bet Limited under Commission account 66162. The app has a 17+ App Store age rating, in line with the Commission’s minimum age for remote gambling. Ante-post horse racing sits among the wider sportsbook verticals, with markets on the major meetings and a focused card on the minor ones. The brand is small in market share and large on the kind of personal service that a small bookmaker can offer — withdrawals handled by a person rather than a queue, occasional bespoke pricing on a name the firm has done its homework on. Punters who want that smaller-firm feel will find it here; punters who want bet365’s depth will not.

The verdict lands on a punter who values a small-bookmaker relationship and a focused ante-post card over the wider market’s depth. A second account for use on a few specific markets, rather than a primary wallet, is where this brand fits.

BetMGM — US heritage, GB-licensed for British customers

BetMGM.co.uk runs under Commission account 39198 in the name of LeoVegas Gaming PLC, the Maltese-listed operator behind several UK-facing brands. The mobile offering carries casino, live dealer and sports, with ante-post on horse racing inside the sportsbook. The welcome mechanics the brand runs — deposit £10 and place a sports bet within 7 days to receive four £10 free bets, valid for 7 days, with minimum odds and an opt-in step — are subject to the 10x wagering cap the Commission brought in on 19 January 2026, and that cap is what an ante-post punter sees in the small print if they take the offer. The brand’s heritage is American, the operator is Maltese-listed, the licence for the customer in Great Britain is British.

The verdict is for the punter who wants a US-heritage sportsbook with a Maltese-listed operator under a GB licence — that is the corporate structure most international online bookmakers in Britain share, and BetMGM is a reasonable representative of the type. The ante-post card is solid rather than the market’s deepest, and the same depth-versus-price trade-off applies as on every mid-tier sportsbook.

The fundamentals of ante-post in Great Britain

The headline facts to keep in mind while reading the rest of the page. Ante-post is a long-term bet on a future event, settled at the price taken on the day the bet was placed, with a non-runner treated as a loss rather than a void. The bookmaker’s margin sits inside every quote; the arithmetic the page runs through below explains what that means for the punter’s actual return. Identity is verified before the first deposit at every licensed brand, GAMSTOP self-exclusion is mandatory for every online licence, and the £150 rolling-30-day vulnerability check kicks in automatically once a customer crosses it. Best Odds Guaranteed does not apply to ante-post on the brands that publish the rule, and the 10x wagering cap on bonuses is the law in Great Britain since 19 January 2026.

The bigger picture is that ante-post sits at the longer end of a longer-running market. British racing produces a thousand meetings a year, the futures market adds a layer of speculator interest to the biggest ones, and the licensed bookmakers compete on depth of card and tightness of price more than on product type. The product itself is the same across the market — settle at the price taken, non-runner loses, void on abandonment — and what differentiates one bookmaker from another is the card’s breadth and the conditions the firm attaches to its offers.

The arithmetic of a price

A bookmaker’s price is built from two numbers. The first is the true probability the market would assign to each outcome of an event if it were set by bettors alone. The second is the bookmaker’s margin, which the bookmaker builds into every quote so that the total of implied probabilities on all outcomes is more than 100%. The gap between that total and 100% is the margin, and it is the bookmaker’s expected profit on every unit of stake the market takes.

Take a two-way market at odds of 1.90 on each side. The implied probability of each side, in isolation, is 1 ÷ 1.90 = 0.5263, or 52.63%. The sum across both sides is 105.26%, and the difference between that sum and 100% is 5.26%, which is the margin. The other way of saying the same thing: the payout share — the share of every unit of stake the market returns to bettors in the long run, ignoring the bookmaker’s running costs — is 1 ÷ 1.0526, or about 95%. A punter who can read a margin of about 5% on a tightly-priced two-way market is reading a competitive bookmaker line; a margin much higher than that is a bookmaker asking for more than the market’s going rate.

The arithmetic scales up. A three-way market with three evenly-priced favourites at decimal odds of 3.40 carries an implied probability of 1 ÷ 3.40 = 0.2941, or 29.41% per outcome, summing to 88.24% — and that is a payout share of 88.24% and a margin of 11.76%, considerably heavier than the two-way example. Ante-post horse racing carries more outcomes than a two-way match, often eight to twenty in a single race, and the margins on those markets reflect it: 12% to 18% is normal on ante-post horse racing for the headline meetings, and tighter margins are a sign the bookmaker is competing for the punter’s stake on that race.

What a free bet is worth in real money

Free bets come with a wrinkle that the marketing rarely mentions. The free-bet amount itself is not returned with the winnings — a £10 free bet at odds of 5.00 returns £50, not £60, because the £10 stake is not paid back. The free-bet value, on a market with a 90% payout share and a price of 5.00, is £10 × (5.00 − 1) ÷ 5.00 × 0.90, or £7.20. The free bet is worth about 72% of its face value at that price and on that market. The arithmetic improves at longer odds (the free-bet value rises toward the stake as the odds rise) and falls at shorter ones. A punter choosing where to use a free bet should look for the longest-priced runner on a market whose margin is competitive — exactly the structure of a long-priced ante-post selection on a major race. The Commission’s 10x cap on wagering requirements means a £10 free bet with a 50x turnover — which would have needed £500 of bets to clear, and was common at one brand — is no longer permitted at any Commission-licensed bookmaker.

The cost the punter pays for clearing a bonus

A bonus with a 10x wagering requirement on a £50 deposit takes £500 of bets to clear, and £500 of bets at a margin of 5% costs the punter about £25 in expected return to the bookmaker — half the bonus face value, in other words, before the punter gets back anything that resembles the bonus. The expected cost is turnover multiplied by the market margin: £500 × 5% = £25. The punter ends up with a deposit plus a bonus minus the cost the bonus takes to clear, and at the 5% margin the deal is roughly break-even before the punter’s time is counted. The commission’s 10x cap was set with exactly this arithmetic in mind, and the headline number — a £500 turnover for a £50 bonus — is the kind of bonus the cap was designed to remove.

The return on a winning bet

A £10 single bet at fractional odds of 5/1 returns the stake plus winnings: £10 + £10 × 5 = £60. The same bet at decimal odds of 6.00 returns £10 × 6.00 = £60. The two notations are the same bet, with the same stake, the same risk and the same return — only the price representation differs. An accumulator’s total odds are the product of each leg’s odds: a four-leg accumulator at 3.00, 2.50, 4.00 and 1.50 has total odds of 3.00 × 2.50 × 4.00 × 1.50 = 45.00, and a £10 stake returns £450 if all four legs win.

The legal frame around an ante-post bet

The Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport, is the regulator of the commercial gambling market in Great Britain. The framework is the Gambling Act 2005, and since the Gambling (Licensing and Advertising) Act 2014 an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based. A Curaçao, Maltese or Gibraltar licence is not a substitute. A bookmaker that holds only a Maltese licence and serves a customer in Great Britain is committing an offence under section 33 of the Gambling Act 2005 aimed at the operator, not at the customer — the customer does not break a law by placing the bet, but loses every protection that comes with a GB licence. The ten bookmakers reviewed above each hold a Commission remote licence for the category “remote general betting standard (real events)” and each appears on the Commission’s public register against the licence holder named in the table.

What the licence buys the punter

The licence carries a set of customer-protection duties that an unlicensed bookmaker is not bound by. Identity is verified before the first deposit or bet, including with a free bet or bonus. Credit cards are banned for gambling in Great Britain, including credit-card-funded payments through an e-wallet. GAMSTOP self-exclusion is a mandatory licence condition for online operators, and any punter registered with GAMSTOP cannot open or use an account at a Commission-licensed bookmaker. A public-record financial vulnerability check kicks in once net deposits exceed £150 in any rolling 30 days, and the operator’s licence requires that check to be run. Wagering requirements on bonuses are capped at 10x since 19 January 2026, and mixed-product promotions — an offer that requires gambling on two or more product types such as betting, casino, bingo and lottery — are banned.

The dispute route for a British customer runs through the Commission and, where appropriate, an approved alternative-dispute-resolution service. A punt at a Curaçao-licensed bookmaker that withholds funds has no such recourse: a complaint to the Curaçao regulator is unlikely to move a British customer faster than a complaint to a Commission-licensed bookmaker would have moved in the first place.

What the licence costs the operator

General Betting Duty is the operator’s tax on gross profits, currently 15% across most categories. From 1 April 2027 a new remote betting rate of 25% applies within it, while remote bets on UK horse racing, bets on self-self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15% — the Government’s published policy paper of 26 November 2025 sets out the schedule. Until 1 April 2027 the remote rate is 15%, and whether the operator passes any of that duty on through tighter odds is not established. The Commission’s statutory levy is a separate charge on the operator; the punter pays no tax on betting winnings in Great Britain, and a professional gambler should ask HMRC or an adviser rather than rely on the position here.

The statute in plain terms

The Gambling Act 2005 and the Gambling (Licensing and Advertising) Act 2014 together require that a bookmaker serving a customer in Great Britain hold a Gambling Commission licence. The Licence Conditions and Codes of Practice (LCCP) set out the player-protection and game-integrity duties that come with the licence, and a Commission-licensed bookmaker is bound by them. The Remote Technical Standards (RTS) set out the technical requirements for online operators. The Commission’s public register is the whole test of whether a brand holds a licence — search it by business name, trading name, domain or account number. The domains a licensed operator uses can end in .com or .co.uk alike, so the domain is no evidence either way; the public register is.

The minimum age for any gambling product in Great Britain is 18. Northern Ireland is outside the Gambling Act 2005 and has its own older law; a GB licence regulates Great Britain, not Northern Ireland, so the language is “GB-licensed” rather than “UK-licensed” for a brand the Commission’s register lists. There is no statutory cap on stakes in sports betting, no state-set deposit or loss ceiling, and no statutory list of permitted markets — an operator holds a licence for a category and offers markets under its own rules.

Frequently asked questions

What is an ante post bet?

An ante-post bet is a fixed-odds bet placed on a future event — most commonly a horse race that is still weeks or months away — settled at the price you took when you placed the bet. The defining mechanic is that a selection which does not run is treated as a loser rather than a void, so the stake is not returned. That single rule is what makes ante-post longer-priced than the day-of-race equivalent: the punter is paying for the market’s uncertainty about the eventual field.

What is ante post betting?

Ante-post betting is the product name for futures markets on horse racing, with the largest ante-post cards running on Cheltenham, the Grand National and Royal Ascot. Each licensed British bookmaker offers the product under its own rules — Tote, bet365, William Hill, Fitzdares, BetMGM, Copybet and the rest — with the same defining features: settle at the price taken, non-runner loses, void if the race is abandoned or moved. The bookmaker’s margin sits inside every quote; the price advantage at long odds is paid for in non-runner risk and in margin.

Does Rule 4 apply to ante post bets?

Rule 4 applies at settlement, against whatever the field of runners has become by then, on the same scale as it does on day-of-race bets. A Rule 4 of 25p in the pound on a horse withdrawn from the race takes 25% off the winnings of the remaining runners whose odds were longer than the withdrawn horse’s. The punter who took 20/1 in November and the favourite in March will see their winning return reduced by the cumulative Rule 4s levied against their horse’s odds between bet-placement and settlement, while the punter whose second-favourite is withdrawn the week before the race has the deduction applied to the winnings of every other runner their bet covered.

How can it be checked that a bookmaker holds a Gambling Commission licence?

The Commission’s public register — at the Gambling Commission’s own site — can be searched by business name, trading name, domain or account number, and lists every current licence holder with the categories of licence they hold and the trading names they operate. A brand that does not appear on the register against a remote betting licence does not hold one. Licensing information on a bookmaker’s own home page is a useful pointer but is no substitute for the register, which is the document the regulator maintains. The brand’s own claim that it holds a licence can be cross-checked against the register in under a minute.

How is the return on a bet worked out from the stake and the odds?

A single bet’s return is the stake multiplied by the decimal odds, or the stake plus the stake multiplied by the fractional odds: a £10 bet at 5/1 returns £10 + £10 × 5 = £60; the same bet at decimal odds of 6.00 returns £10 × 6.00 = £60. An accumulator’s total odds are the product of each leg’s odds at the time the bet was placed — a four-leg accumulator at decimal odds of 3.00, 2.50, 4.00 and 1.50 has total odds of 45.00, and a £10 stake returns £450 if all four legs win. Each ante-post leg settles at the price it was taken at, not at the starting price on the day.

What is the bookmaker’s margin and how can it be seen in the odds?

The margin is the percentage the bookmaker builds into every quote so that the total of implied probabilities across all outcomes of a market is more than 100%. A two-way market priced at 1.90 on each outcome carries an implied probability of 1 ÷ 1.90 = 52.63% per side, summing to 105.26% — a payout share of about 95% and a margin of about 5%. Tighter margins mean a competitive bookmaker line; looser margins, or a market with more outcomes, push the figure higher. Ante-post horse racing typically runs at margins of 12% to 18% on the headline meetings, reflecting the number of runners in a typical race.
