NFL Bookmaker Hold Percentages: How Paddy Power, Sky Bet and bet365 Compare

The two prices that look identical and are not
A punter in a Reddit thread once asked me whether it really mattered which UK bookmaker he used for NFL spreads. The headline prices, he pointed out, looked basically the same – every book was offering 10/11 on both sides of the standard NFL spread. I sent him a screenshot of the same game across four UK books and a calculation of the two-way overround on each. The numbers told the story: same headline price, four different effective holds, with the worst book charging about 50% more vig than the best book over the season. The punter who sticks to one UK bookmaker because the prices look identical is the punter quietly losing the equivalent of one extra losing bet per month to structural pricing differences. After seven years of doing this comparison, I think hold-percentage literacy is the second cheapest skill upgrade a UK NFL punter can make.
The break-even at standard −110 American juice is 52.4%, which equates to a two-way overround of roughly 4.5%. Different books, despite identical-looking prices on the surface, run different overrounds. The gap is where the season is won or lost.
Defining hold versus overround
Hold and overround are related but not identical concepts. Overround is the sum of the implied probabilities of all selections in a market, expressed as a percentage. A two-way NFL spread at 10/11 each side has an implied probability of 52.4% on each side, summing to 104.8%. The 4.8 percentage points above 100% is the overround.
Hold is the bookmaker’s effective margin expressed as a percentage of total handle. It is approximately the overround divided by the overround plus 100. For a 104.8% overround market, hold is 4.8 / 104.8, which is approximately 4.58%. The two figures are close in low-margin markets but diverge in high-margin markets. A market with a 130% overround has an effective hold of about 23%.
Bookmakers think in overround when they price markets. Punters should think in hold when they compare books, because hold tells you what fraction of total stake the bookmaker keeps over the long run. The 4.5% hold on a standard NFL spread is what defines the 52.4% break-even threshold.
NFL two-way overround across UK books
The two-way overround on NFL point spreads varies meaningfully across UK books. Across the games I have checked over the last two seasons, bet365 and Paddy Power tend to run overrounds in the 104.5-105.5% range on standard spreads, which is at the tighter end of the UK market. Sky Bet typically runs slightly wider, around 105-106%. Betfair Exchange offers something structurally different – the back/lay format means the effective margin depends on commission rather than overround, but on liquid NFL markets the effective commission-adjusted hold is often lower than any traditional bookmaker.
The difference between a 104.5% overround and a 106% overround does not sound large, but it compounds aggressively over a season. A punter placing 100 spread bets per season at £20 each – total turnover £2,000 – pays roughly £90 in vig on the 104.5% book and £120 in vig on the 106% book. The £30 gap on £2,000 of turnover is the structural cost of betting on the wrong book without realising it.
Prop and SGP hold comparison
Where UK books vary much more dramatically is in prop markets and same-game-parlay products. Two-way prop markets – passing yards, rushing yards, receiving yards – typically run overrounds of 108-112% on most UK books, which translates to hold percentages of 7.5-11%. Multi-way prop markets like first touchdown scorer run overrounds of 125-135%, translating to hold percentages of 20-26%.
Same-game parlay holds are the highest of all. A typical three-leg NFL SGP carries an effective hold of 12-16%, and four-leg SGPs run 18-22%. The compounding of correlation adjustments across legs creates these large effective margins. The headline takeaway is that SGP holds are several times higher than standard spread holds, which is why bookmakers promote SGPs so aggressively and why disciplined punters limit their SGP volume sharply.
Where UK books tighten the line and where they shade
UK books are not consistent in their pricing across all NFL markets. Each book has categories where it prices tightly to attract volume, and categories where it shades wider because its competitors are also priced wide. bet365 has historically priced point spreads and totals tightly relative to UK competitors, particularly in the hours close to kick-off, which is when sharp money arrives. The trade-off is that prop pricing on bet365 is sometimes wider than competitors. Sky Bet and Paddy Power have moved their pricing closer together since the Flutter UK and Ireland platform consolidation, with bet builder pricing now consistent across both brands.
The 80% of NFL bettors who maintain accounts at two or more bookmakers benefit from these structural differences directly. A spread bet placed on bet365, a prop bet placed on Paddy Power, and a futures bet placed on Sky Bet captures the best pricing each book offers in its category – and over a season the cumulative savings on vig alone can run into hundreds of pounds at modest stake sizes. Among under-35 NFL bettors specifically, 60% place three or more bets per week, and that volume rewards multi-account discipline more than any other betting habit.
Using hold data as a punter
The practical workflow for incorporating hold awareness into your weekly betting is shorter than punters expect. The first step is to maintain accounts at the three or four UK books that consistently price tightly on the markets you bet most. For most NFL punters that means bet365, Sky Bet or Paddy Power (interchangeable on most markets given the platform consolidation), and at least one of Betfair Exchange or William Hill for cross-checking.
The second step is to spot-check the overround on any market before you bet, particularly on prop markets and SGP products. The calculation takes thirty seconds: sum the implied probabilities of the listed prices, compare against 100%, and decide whether the excess is reasonable for the market type. A two-way market overround above 106% is wide for spreads but reasonable for props. A SGP overround above 122% is wide for a three-leg ticket and indicates you should look elsewhere.
The third step is to compare across books before placing the bet. The 90 seconds spent checking prices across two or three UK books is the cheapest expected-value improvement available. As one industry trading source described the recent consolidation in UK NFL product pricing, customers now have access to hundreds of new markets through bet builder products – but the price competition between groups means the punter still has to do the comparison work each time. The connection to broader operator-by-operator differences in NFL coverage is unpacked in our companion piece on bet365 NFL markets versus UK competitors. The honest takeaway is that the books are not interchangeable. Treating them as if they were is the cleanest way to leak money over a UK NFL season.
Which UK bookmaker offers the lowest hold on NFL point spreads?
bet365 and Paddy Power consistently run the tightest two-way overrounds on standard NFL spreads, typically 104.5-105.5%, which translates to effective holds of 4.3-5.2%. Sky Bet runs slightly wider, around 105-106%. Betfair Exchange offers a structurally different model – back/lay with commission – that often produces effective holds below 4% on liquid NFL markets. The exact pricing varies game to game, so spot-checking each market matters.
Is the hold higher on NFL SGPs than on straight totals?
Substantially higher. A two-way NFL total at 10/11 each side runs an effective hold of roughly 4.5%. A three-leg same-game parlay carries an effective hold of 12-16%, and a four-leg SGP often sits at 18-22%. The hold differential is structural – bookmakers price correlation adjustments across legs in their favour – which is why disciplined punters limit SGP volume tightly relative to straight bets.
