Stock-car racing does not headline the British betting menu the way football does, but it has a quiet home on the apps of the major UK-licensed bookmakers. The 2026 NASCAR Cup Series runs 36 points-paying races plus the Cook Out Clash, the Duel at Daytona and the All-Star Race, opening with the Daytona 500 on 15 February 2026 and ending at Homestead–Miami on 8 November 2026. Across that schedule, a punter in Great Britain can back a single driver, group several in combination bets, sit on the race in play, and pull a bet back early — but every price on every market carries the bookmaker’s margin inside it, and the size of that margin decides how much of every pound staked the bookmaker keeps on average.

This guide is about those choices and their cost. It walks through the markets bookmakers offer, the bookmakers licensed by the Gambling Commission who carry them, the rules that govern remote betting in Great Britain, the offers tied to a NASCAR bet, and the arithmetic by which a stake turns into a return.

NASCAR betting odds: how a price is built and what it pays

The price on any driver is the price the bookmaker chooses to publish, and the bookmaker’s margin is the difference between the “true” probability of all outcomes and 100 %. On a two-way market at decimal odds of 1.90 / 1.90 — written in fractional form as 9/10 — the arithmetic is the same as for a head-to-head match. The payout share, that is the share of every pound staked the bookmaker returns to customers on average, is 1 ÷ (1/1.90 + 1/1.90), which is 1 ÷ 1.0526, or about 95.00 %. The margin is therefore roughly 5.00 % on this market, by far the most common shape for an even-priced NASCAR head-to-head. On a typical outright winner market with twenty or thirty drivers, the margin runs higher, often somewhere in the 6 % to 10 % band for an evenly priced field and rising further as the long tail thins out. The band is what to compare across bookmakers; the headline price next to it tells the reader almost nothing.

The £10 bet on a driver at decimal odds 3.50 pays back £35 if it wins — £10 of stake returned plus £25 of profit — and £10 on a driver at 1.90 pays back £19. A combination bet with two drivers at 3.00 and 4.00 multiplies the prices into 12.00, so a winning £5 stake returns £60. The stake is never returned on a free bet, which is the rule that turns a £10 free bet at 3.00 into an expected £6, not into a £20 win.

The picture sits between two pressures. The bookmaker wants the margin as wide as the market will bear, because margin is profit. The punter wants it as narrow as possible, because a narrow margin means more of every pound staked is paid back on average. The race calendar is the third pressure: a quiet midweek race at a short oval carries more line width than a Cup round at Daytona in February, and the headline price on the favourite at a quiet track is where the bookmaker’s edge shows up most clearly.

Betting markets bookmakers run on NASCAR

The Cup Series race weekend opens a number of distinct markets, and each carries its own margin. The outright winner market is the headline — pick the driver who finishes first — and the price on the favourite at Daytona tends to sit between 4.00 and 6.00, with the field stretched behind it. Each-way terms vary by race and by bookmaker: typically one quarter of the odds for a top-three or top-five place, depending on the size of the field, with the place paid separately to the win. An each-way bet is two equal-stake bets, so the stake doubles and the payout is the win part plus the place part.

The head-to-head or match-bet market pits two drivers against each other, both must start, dead-heat rules apply — and the margin on this market is usually the tightest on the card, because only two prices sit on it. A typical even-money head-to-head at 1.90 / 1.90 carries about 5 % margin; a 1.80 / 2.00 line carries closer to 6.5 %. The qualifying or starting-grid market runs on Saturday and pays out on the official grid position rather than the race result. Stage markets break the race into segments (NASCAR’s 2026 format splits the longer races into stages) and settle on the winner of each stage.

Props and exotic markets round out the card: the winning manufacturer (group of manufacturers, Chevrolet / Ford / Toyota), the lead changes total, the number of cautions, fastest lap, and the margin of victory. The number of cautions line is settled on the official NASCAR count, and lead-change totals are settled on the official lap-by-lap data; both lines are quoted with an over and an under and the margin on each side is built into the prices on either side. Bet Builders let a punter combine markets from one race into a single bet — winner and winning manufacturer, for example — and the price multiplies with the selection. Settlement rules follow the bookmaker’s own house rules, and those rules say how a non-runner, a rain-shortened race and a dead heat are handled.

The 2026 Cup Series carries one structural change worth flagging at the markets layer. The playoff takes the top 16 drivers in points after 26 races, the win-and-you’re-in rule is gone, and playoff starting points are staggered by regular-season standings. The effect for the outright market: before the playoff cut, the field is priced on regular-season form; after it, prices move sharply as four drivers drop out at each round and the field narrows.

NASCAR betting sites in Great Britain: the licensed field

Ten bookmakers licensed by the Gambling Commission carry NASCAR outright and head-to-head markets on the 2026 Cup Series. They are listed below in the order research places them, and the licence number beside each is what the Commission’s public register returns at the date of checking. Every brand named here is GB-licensed for remote general betting on real events; no unlicensed operator is on the list.

No single brand on this list is “the only” licensed one. The Commission’s register lists several hundred remote betting licences; the ten here are a cross-section of the market, not the whole of it. Choosing among them is a question of which market depth, which promotional terms and which app suit the punter; the table below lays out the licence picture at a glance, and the operator write-ups that follow take each one in turn.

QuinnBet: tight racing promos, narrow sport menu for NASCAR

QuinnBet’s Best Odds Guaranteed on Irish and UK horse racing — paying at the bigger of the early price or the starting price, capped at £150 per customer per race — does not touch NASCAR, and the cup series markets are quoted outright without a BOG equivalent. The platform does carry outright winner, head-to-head, stage and qualifying markets on the Cup Series, and the margin on the outright field sits in the typical 6 % to 9 % band for an evenly priced twenty-driver card. The Commission account is 61011 under QuinnBet (Gibraltar) Limited, and Best Odds Guaranteed is verified from the operator’s own help page.

The verdict: QuinnBet is worth taking for the racing menu it does cover, and a NASCAR punter can place outright and head-to-head bets at prices that look competitive against the wider market. The sport menu is the limit; if the reader wants a Bet Builder that combines race and player props on a single ticket, QuinnBet is the wrong shop.

Betway: weekly free-bet club and a broad sportsbook

Betway’s Free Bet Club hands back up to £10 in free bets every week after the punter spends £25 or more on sports. Two £5 free bets land the following week once the qualifying spend is met. The Free Bet Club does not depend on the sport — the qualifying spend can include NASCAR — but the free bet is paid back with credit and the stake is not returned on a win. The app carries outright and head-to-head markets on the Cup Series, plus selected props, and the Commission account is 39372 under Betway Limited.

The verdict: Betway suits a NASCAR punter who bets on multiple sports each week and wants a steady drip of free bets rather than a one-off sign-up offer. The £25 weekly threshold is light enough that a small-stake punter can clear it without changing the bet. A punter whose entire betting life is one Cup Series race a week will find the threshold harder to clear without padding the qualifying spend with bets they would not otherwise make.

Bet600: starting-price racing guarantee, modest sport menu

Bet600’s Best Odds Guaranteed pays at the starting price if the SP is bigger than the early or show price taken, and the rule applies on horse racing rather than on motorsport. NASCAR markets on Bet600 are quoted outright and the field is priced in line with the wider market; the cup series outright winner sits in the typical margin band for an even-money card. The Commission account is 44731 under Tyche Tech Limited.

The verdict: Bet600 is a small-stakes shop for a punter who wants a clean NASCAR outright market without the noise of an oversized sportsbook. The headline BOG is a horse-racing tool and does not extend to NASCAR. A punter whose primary interest is racing will find the BOG useful; a punter whose primary interest is NASCAR will find the menu limited.

Geoff Banks: ante-post motorsport and live in-play pricing

Geoff Banks’ app carries live in-play prices and ante-post prices on future events, and the cup series markets are quoted both outright before the race and in-play during the race. Ante-post markets let a punter take a price on the championship weeks before the running starts; in-play markets settle on the official race result, with the bookmaker’s own suspension rules applying during cautions and stage breaks. The Commission account is 54095 under GB Sports Advisors Limited.

The verdict: Geoff Banks suits a punter who likes to take a price early and trade through the race weekend. Ante-post markets carry their own risks — non-runner rules and Rule 4 deductions apply if the field changes — and a punter who takes a price on a driver who fails to qualify loses the stake under the operator’s standard rule. A punter who only bets on race day will not use the ante-post side at all.

London Bet: broad market coverage, casino-mixed app

London Bet’s app combines a sportsbook — football, tennis, horse racing, greyhounds, darts, golf, cricket, NFL, NBA, MLB and snooker — with Pragmatic Play casino slots and live in-play betting. The sports menu does not name NASCAR by category, and the cup series markets are quoted on an event-by-event basis rather than as a year-round menu. The Commission account is 66162 under Thistle Bet Limited.

The verdict: London Bet is a secondary app for a punter who already has a primary NASCAR bookmaker and wants a casino-mixed alternative. The sports menu is built around UK and US team sports and the motorsport coverage is lighter than the dedicated shops on this list. A punter whose primary interest is NASCAR outright and head-to-head markets will find the dedicated shops ahead on depth.

888sport: BetFinder form tools and daily boosted odds

888sport’s app carries pre-match and in-play betting, Cash Out, Bet Builder, racing streams, BetFinder form tools and a live bet feed, with daily boosted odds on selected markets. The cup series outright, head-to-head and props are quoted at prices that move during the race, and the BetFinder form tool lets a punter filter the field by track type and recent form before placing a bet. The Commission account is 39028 under 888 UK Limited.

The verdict: 888sport is a generalist sportsbook with a NASCAR menu that sits in the middle of the pack. The BetFinder form tool is the difference: a punter who weights form by track type gets a small edge on outright markets, and the daily boosted odds give a small saving on a single bet. The margin on the boosted markets is wider than on the standard markets, because the boost is funded out of the bookmaker’s margin elsewhere — a £10 boosted bet at the headline price pays back the same as a £10 standard bet at the un-boosted price only if the boosted line is genuinely better than the market line.

bet365: Bet Builder+, in-play streams and Super Boosts

bet365 is the official global betting partner of the UEFA Champions League, its app is described as the most downloaded sports betting app in the UK, and its NASCAR menu carries outright, head-to-head, stage, qualifying and props markets with in-play pricing through the race. Bet Builder+ combines markets from one race into a single bet, available pre-match and in-play, and Super Boosts run daily on selected markets. In-play streams of selected races are available to funded account holders, and Bet Track and Match Live let a punter follow a bet through the stages. The Commission account is 55148 under Hillside (UK Sports) ENC.

The verdict: bet365 is the strongest all-round choice for a NASCAR punter who wants in-play pricing, race streams and a Bet Builder on the same app. The depth of the menu and the in-play coverage are ahead of the rest of the list, and the Super Boosts are a small saving on a single bet rather than a structural edge. A punter whose bets are all outright ante-post on Saturday morning will not use the in-play side and can find a tighter margin on a smaller bookmaker.

Copybet: best-odds racing guarantee and same-race payouts

Copybet pays Best Odds Guaranteed all day every day on UK and Irish racing and pays first past the post on horse racing even if the winner is later disqualified. The BOG rule applies to horse racing rather than NASCAR, and the cup series markets are quoted outright and head-to-head. The Commission account is 53774 under Copybet UK Limited.

The verdict: Copybet is a horse-racing shop that also carries NASCAR. The BOG and first-past-the-post payout are tools, not NASCAR offerings, and the cup series menu sits in the middle of the pack on depth. A punter whose interests split between racing and NASCAR will use both sides; a punter whose only interest is NASCAR will find a dedicated shop ahead.

Fitzwilliam Sports: Dublin bookmaker with capped membership

Fitzwilliam Sports is a Dublin bookmaker with capped membership and a “High Stakes Welcome” subject to compliance criteria. The signup is gated, and the typical member is a higher-stakes punter referred by an existing customer or an affiliated tipster. The sportsbook carries outright and head-to-head markets on the cup series, plus selected props, and the Commission account is 48760 under SBKI Limited.

The verdict: Fitzwilliam Sports suits a higher-stakes NASCAR punter who has been invited and wants a personal account manager and a higher stake ceiling than the generalist apps. The capped membership means a casual punter cannot open an account, and the welcome offer is subject to criteria the operator does not publish. A punter who is not invited has no path to the bookmaker, and the verdict for that punter is the door stays closed.

LiveScore Bet: Bet Builder up to ten selections

LiveScore Bet’s Bet Builder allows up to 10 selections per match and covers match result, both teams to score, corners, total goals, player scoring and card markets — a football-shaped tool that does not extend to NASCAR combinables on the cup series. The cup series markets on LiveScore Bet are quoted outright and head-to-head without a same-race multi. The Commission account is 56859 under LiveScore Betting and Gaming (Gibraltar) Limited.

The verdict: LiveScore Bet is a football-first bookmaker with a NASCAR menu that is narrower than the dedicated shops on this list. The Bet Builder is the headline feature and it does not extend to NASCAR combinables on the cup series. A punter whose interests are split between football and NASCAR will use both sides; a NASCAR-only punter will find the dedicated shops ahead on depth.

NASCAR betting legality in Great Britain

Every bookmaker named above holds a remote general betting standard (real events) licence issued by the Gambling Commission under the Gambling Act 2005. The Commission’s public register can be searched by business name, trading name, domain or account number, and the licence details in this article are verified against the register at the date of checking. The Commission’s role is to license the whole commercial market under the Act; there is no state monopoly and no cap on the number of licences.

The relevant statute is the Gambling Act 2005, covering Great Britain — England, Scotland and Wales. Northern Ireland is outside the Act and runs on its own older law. 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 at the point of consumption. Providing gambling facilities in Great Britain without the licence the Act requires is an offence under section 33 of the 2005 Act.

For a punter in Great Britain the practical consequences are these. Identity verification runs before the first deposit — name, address and date of birth are checked, including on a free bet or bonus, and no anonymous play is possible at a licensed site. Source-of-funds questions are normal under money-laundering rules at higher spend. Credit cards are banned for gambling in Great Britain (since 14 April 2020), including credit-card-funded payments through an e-wallet. There is no state-set cap on stakes in sports betting; the operator sets its own maximum stake and may restrict customers.

Financial spread betting sits outside the Commission’s remit and is regulated by the Financial Conduct Authority. Spread-betting losses can exceed the deposit, and the FCA-supervised side of an operator’s business runs under FCA rules. Spread betting on sports events that is not a financial contract sits inside General Betting Duty, and the FCA-supplied fact on this page is the regulatory line, not the trading recommendation.

Responsible gambling and player protection in Great Britain

GAMSTOP is the national multi-operator online self-exclusion scheme and a mandatory licence condition for online operators since 31 March 2020. A punter who registers with GAMSTOP is excluded from every GB-licensed online operator for six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays in place for a further seven years unless the punter asks GAMSTOP to remove it. GAMSTOP covers online sites and apps; betting shops use a separate self-exclusion service.

A financial vulnerability check applies to remote operators when a punter’s deposits minus withdrawals exceed £150 in a rolling 30 days: it is a public-record check, looking at things like bankruptcy or county court judgments, not an income check and not a credit reference check. Financial risk assessments are announced in a staged plan, with no start date. The first changes to deposit limits have applied since 31 October 2025; a second phase was postponed to 30 September 2026 and whether it is live is not established. There is no state-set deposit or loss ceiling for betting; limits are the punter’s choice.

Help is available through GamCare (the National Gambling Helpline), GambleAware, the NHS gambling clinics network and Gamblers Anonymous. The Commission’s own complaints route is open to a punter who has tried the operator’s complaint process and is not satisfied with the response, and an approved alternative dispute resolution (ADR) provider is on hand for that escalation.

Cryptocurrency and NASCAR: payment reality at licensed bookmakers

A British named-account rule, a state list of permitted payment methods and any rule for or against cryptocurrency deposits at licensed operators are not established. Identity verification before the first deposit means no anonymous play is possible at a licensed site, and a punter looking for a pseudonymous deposit on a NASCAR bet will not find one at any of the ten bookmakers on this list. A crypto wallet does not, on its own, defeat the verification step: the operator still checks name, address and date of birth before the first bet, and the wallet’s transaction history is visible to the operator if it asks.

At the time of checking, none of the GB-licensed bookmakers on this list quote cryptocurrency as a deposit method. The practical deposit set at a GB-licensed sportsbook is debit card, bank transfer and selected e-wallets, and a punter looking for a Bitcoin, Ethereum or Litecoin deposit will need an offshore account that is outside the Commission’s licence. That bookmaker does not have a GB licence, and the protection that comes with a GB licence — GAMSTOP, ADR, the Commission’s complaints route, the £150 vulnerability check, the 10x bonus cap — is not in place at the offshore side. The promotion that names crypto payments and NASCAR together is, in nearly every case, an offer from an operator that is not on the Commission’s register, and the cost of taking that offer is the loss of every protection named in the section above.

NASCAR betting offers and promotions: what the bonus actually costs

The promotion rules in force since 19 January 2026 cap wagering requirements on bonuses at 10x, so a £10 bonus with a 50x requirement would need £500 of bets to clear; under the cap no more than £100 of bonus needs that much turnover. Mixed-product promotions — an offer that requires gambling on two or more product types such as betting, casino, bingo and lottery — are banned. Whether the cap applies to free bets with no wagering condition, and any cap on the money value of a bonus, are not established.

The numbers above are the arithmetic that turns the marketing word “bonus” into its real cost. A £10 bonus with a 10x wagering requirement on a sport market at 1.90 needs £100 of qualifying bets; at a margin of 5 %, the expected cost of clearing the offer is £5, so the £10 bonus is worth £5 in expected return. A £10 free bet at 3.00 with no wagering requirement pays back the £20 of profit at the price, but the stake is not returned, so the expected value is £10 × (3.00 − 1) ÷ 3.00 × 0.95, or about £6.33. That number is the average over many bets at that price on that market, not a guaranteed return on any single bet.

Each operator’s offer keeps the type the terms state. A cash bonus stays a cash bonus with a wagering requirement; a free bet stays a free bet whose stake is usually not paid back with a win; a “risk-free” bet refunded as a free bet is not a refund in money; a price boost, an accumulator insurance and a cashback each stay what they are; a deposit-gated package stays deposit-gated. The marketing word and the arithmetic cost are two different things, and the latter is what the offer is worth.

Two specific examples from the operator write-ups above illustrate the gap. William Hill’s Football Acca Boost — not a NASCAR tool, but illustrative of the wider market — covers accas of two or more legs at 1/5 or bigger (1.20 in decimal), with the boost running from 3 % on a double to 200 % on twenty or more legs and a maximum boost of £10,000 per online bet. The boost is paid back as bonus funds with the same wagering requirement as the headline offer, and the cap is the ceiling on the headline win. Betway’s Free Bet Club gives up to £10 in free bets every week after £25+ in qualifying stakes; two £5 free bets land the following week once the qualifying spend is met, and the stake is not returned on a free-bet win. Both examples turn the marketing word into the wagering requirement and the stake-not-returned rule, and both examples are how the offer’s cost is read.

NASCAR betting apps and mobile experience

A mobile-first NASCAR punter in Great Britain has the choice between an app and a mobile browser, and the choice matters for two reasons. First, the app carries push notifications on price moves, in-play suspensions and cash-out offers, and a browser punter has to keep the page open. Second, the app carries biometric login on most modern handsets, and a browser punter types a password every visit.

The ten bookmakers on this list all have an app on the UK App Store, and the descriptions on the store listings are summarised in the operator write-ups above. bet365 is described as the most downloaded sports betting app in the UK; 888sport and Copybet run their own apps with Bet Builder and Cash Out; QuinnBet, Betway, Bet600 and the others run apps that carry the same sportsbook as the desktop site. The mobile experience is a question of preference: a punter who bets in play on Sunday afternoons wants the push notifications and biometric login; a punter who bets once a week on Saturday morning wants neither and saves the storage on the handset.

Browser play is supported by every bookmaker on this list, and a punter who shares a handset, who bets from a work laptop, or who simply does not want another app on the phone has the same markets and the same prices through the browser. The browser is slightly slower than the app on in-play suspensions, and that is the only practical difference.

Live NASCAR betting and cash out

GB-licensed bookmakers offer in-play betting on motorsport including NASCAR, and the controls are the operator’s licence conditions and customer-protection duties rather than a statutory rule. In-play odds move with the race — a long green-flag run typically shortens the favourite and lengthens the field, a caution bunches the field and resets the prices — and a punter who watches the race with the app open sees the prices move in real time.

Cash Out is offered by most of the bookmakers on this list, including 888sport and bet365, and lets a punter settle a bet before the race finishes at a price the bookmaker quotes at the time of cashing out. The Cash Out price carries the bookmaker’s margin inside it, and the wider the margin the worse the cash-out price. A Cash Out at the same price as a fair settlement is a marketing word, not a product feature; the Cash Out price is always slightly worse than a fair settlement, and the gap is the operator’s cut on the early settlement. The punter is taking the early settlement to lock in a profit or to limit a loss, and the operator is taking the early settlement to lock in its margin; the exchange is the bet.

In-play streams are offered on selected races by bet365 and 888sport, and a funded account holder can watch the race with the betting slip open. The streams carry a short delay on the live broadcast, and the prices move with the broadcast delay — a punter watching the broadcast directly sees the race slightly ahead of the bookmaker’s feed, and the bookmaker’s suspension rules apply during cautions and stage breaks. The punter who watches the bookmaker’s feed rather than the broadcast is seeing the race as the bookmaker sees it, and the prices are consistent with that feed.

NASCAR betting predictions, picks and bankroll

Predictions on a NASCAR race are a forecast, and the forecast has to be priced against the bookmaker’s margin. The Cup Series field is a long, tightly packed one — twenty or thirty cars on a one-and-a-half-mile oval, with the same car count at a short track — and the favourite’s price typically sits between 4.00 and 6.00, with the field stretched behind it. The price is set by the bookmaker and the margin sits inside it; the punter’s job is to find prices that are too big, which is to say, prices that pay more than the true probability of winning implies.

A bankroll is the punter’s reserve for the season, and the rule is to stake a small, fixed percentage on each bet — typically 1 % to 2 % of the bankroll per selection. The percentage is set by the punter’s appetite for a losing run, and a 10 % stake per bet is a different kind of bankroll management. The bankroll is separate from the punter’s day-to-day money, and the bankroll is the limit on what the punter can lose in a season.

Best-bets-today articles name a selection for the day’s race; the selection is a forecast and the forecast is a guess. A punter who follows the forecast is paying for someone else’s view of the field, and the cost is the subscription or the affiliate cut, not the price on the bet. The forecast is not a system that wins, and the punter who treats it as one is paying for a habit. The Cup Series is a one-off race format; six consecutive races are six separate forecasts, and the streak is a streak on the forecast rather than a streak on the punter’s bets.

Frequently asked questions

How do I place a bet on NASCAR from Great Britain?

Open an account with a GB-licensed bookmaker, complete identity verification (name, address, date of birth), deposit by debit card or bank transfer, and pick a NASCAR market. Outright, head-to-head, each-way and stage markets are quoted on the Cup Series. The stake is debited when the bet is placed, and the return lands when it settles.

Where can I bet on NASCAR in Great Britain?

Any GB-licensed bookmaker carries NASCAR outright and head-to-head markets. The bookmakers in this guide — QuinnBet, Betway, Bet600, Geoff Banks, London Bet, 888sport, bet365, Copybet, Fitzwilliam Sports and LiveScore Bet — are a cross-section of the market. The Commission’s public register lists the complete set of licensed operators.

How do I bet on a NASCAR race weekend?

The race weekend opens the outright winner market early, with head-to-head, qualifying, stage and props markets from Friday. Pick a market, pick a selection, set the stake, and place the bet. In-play markets run during the race, and Cash Out is offered by most bigger bookmakers. Settlement follows the bookmaker’s house rules.

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

Search the Commission’s public register by business name, trading name, domain or account number. The licence details returned — categories, holder, account number — confirm whether a brand is licensed. A licensed operator runs the GAMSTOP scheme and 10x bonus cap, and accepts ADR escalation through an approved provider.

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

Return = stake × odds. On a £10 bet at 3.50 odds, the return is £35, with £10 stake and £25 profit. On a £5 combination bet at 3.00 and 4.00, odds multiply to 12.00, returning £60. The stake is not returned on a free bet: a £10 free bet at 3.00 wins £20 profit.

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

The margin is the share of every pound staked the bookmaker keeps on average. On a two-way market at decimal odds 1.90 / 1.90 the payout share is 1 ÷ (1/1.90 + 1/1.90), or about 95.00 %, and the margin is therefore about 5.00 %. The wider the prices on a market, the higher the margin. A typical outright winner market on the Cup Series carries 6 % to 10 % margin; a head-to-head at 1.90 / 1.90 carries about 5 %.
