How NFL player props are priced: where the line comes from, why it sits at the median, the juice on each side, alternate lines, same-game parlays and prediction markets.
The line: a sportsbook sets a prop near the player's median outcome, the number he's as likely to finish under as over, and then adds juice to both sides.
Median vs average: yardage outcomes are lopsided, because one long gain can inflate a player's average, so the average usually sits above the line.
Juice: a prop priced -115 each way holds 6.52% of the money wagered, against 4.55% on a -110 point spread. Uneven prices such as -130 and +100 show which side the book's leaning toward.
Same-game parlays: correlated legs are priced together. New Jersey books kept 17.3% of what bettors put on parlays in 2026 through September.
Prediction markets: a prop is a contract priced by users' orders. On Novig, a single pre-game prop carries no fee for either side.
An NFL player prop is a bet on one player's stat line: passing yards, rushing yards, receptions, or whether he scores a touchdown. A sportsbook prices it in two steps. It projects the player's range of outcomes from his recent usage and the matchup, and sets the line where it expects half the outcomes to fall on each side. Then it puts a price on both sides that adds up to more than 100% in implied probability, and the excess is what it keeps.
After the line opens, money and news move it. A receiver's yardage line can drop when his quarterback is ruled out, and teams name their inactive players 90 minutes before kickoff, which reprices a lot of props at once.
On a prediction market, a prop is a contract that pays $1 if the player clears the number, and its price comes from users buying and selling against each other. There's a posted platform fee where one applies.
Player stats aren't symmetrical. A running back's yardage has a floor a little below zero and no fixed ceiling, and one 70-yard touchdown can double his total. That long tail drags the average above the typical game.
Unabated, a betting analytics site, illustrates this with five late-season games from Deebo Samuel: 21, 37, 47, 48 and 149 receiving yards. The median of those five is 47, and the average is 60.4, so they're about 13 yards apart. Unabated puts a line built from that stretch at about 47.5: he went over that number in two games and under it in three. Set at 60.5, the line would have gone under in four of the five.
That's why a projection built on averages tends to point at overs. A bettor comparing a season-average figure with a posted prop line is comparing two different measures, and the posted line is built on the median.
Props cost more to bet than spreads at a sportsbook. Odds Reference keeps props out of its closing-line data and says retail books are widely reported to charge more on them than on spreads. The common prices compare like this:
Prices on the over and under | Sum of implied probabilities | Hold |
|---|---|---|
-110 / -110 | 104.76% | 4.55% |
-115 / -115 | 106.98% | 6.52% |
-120 / -120 | 109.09% | 8.33% |
-130 / +100 | 106.52% | 6.12% |
Uneven prices show the book's lean. At -130 on the over and +100 on the under, the over implies 56.52% and the under 50%. Take the margin out evenly and the over is about a 53% outcome, so the book expects the player to clear the line a little more often than not, without moving the number itself.
Touchdown scorer props work differently. When a book lists an anytime touchdown price with no "no" side, there's nothing to add up, and the margin can't be measured from the board. The way to check one is to convert the yes price to a probability and compare it with another app's price on the same player.
Alternate lines price the same player at different numbers. A receiver might be 64.5 yards at -115, with 79.5 and 99.5 available at longer prices. Each number is a point on the same projected range of outcomes: the book reads off how often it expects the player to clear each number and prices that probability with a margin on top.
A ladder spreads a stake across several of those lines. If the player clears the highest rung, every bet wins. If he finishes between two rungs, the lower bets win and the upper ones lose. The bettor is still taking the over; the ladder just splits the money across more of the curve, and each rung carries its own margin.
Props are the usual legs in a same-game parlay, and those legs aren't independent. If a quarterback throws for 300 yards, his top receiver probably had a big day too. A sportsbook prices the combination as one bet. In a worked example from the Wizard of Odds, three legs from one game (a team to win, its quarterback over 275 passing yards and the total over 48.5) hit 16.0% of the time if treated as independent and 21.2% once correlation is counted. The book pays accordingly, at shorter odds than multiplying the legs would give.
The margin compounds as well. Two -110 legs priced as independent pay +264 against a fair +300 for two coin flips, a hold of 8.88%. In New Jersey, books won 17.3% of parlay handle in 2026 through September. The lowest juice NFL betting apps guide shows what parlays cost on each app.
A prediction market prop is a yes/no contract. An over priced at 52 cents is the market's 52% estimate that the player clears the line, and buying 100 contracts costs $52 and pays $100 if he does. The "no" side of the same contract is the under, so both sides are there, and the gap between the best buy and sell price is visible on the order book.
The cost depends on the platform's fee:
Novig: a single pre-game prop is a straight trade, and Novig's fee schedule lists no fee for either side of one.
Kalshi: NFL yardage contracts carry a taker fee that peaks at $1.75 per 100 contracts at 50 cents and no maker fee. Its anytime and first touchdown contracts charge makers too.
ProphetX: 2% of net winnings on straight trades, so a losing prop doesn't cost anything extra.
Here's a running back at 64.5 rushing yards. A sportsbook dealing -115 on both sides needs $57.50 to win $50 on the over. On a prediction market at 50 cents with no fee, 100 contracts cost $50 and win $50.
On thinly traded players, prices depend on who's posting orders, so the gap between the best buy and sell price can be wide on backups and depth receivers.
On cost, a pre-game straight prop on Novig carries no fee, and ProphetX charges only on winners. For menu depth, DraftKings, FanDuel and BetMGM post deep NFL prop boards with alternate lines and same-game parlay builders. Kalshi lists touchdown scorer and yardage contracts. The best NFL player prop betting sites ranking compares each one in detail.
Novig requires users to be 21 and isn't available in Arizona, Michigan or Nevada. Its status in Ohio is unsettled after the state's casino regulator sent it a cease-and-desist letter in October 2026.
They project the player's range of outcomes, set the line near the median so each side's about equally likely, and put a margin on both prices. Injury news and betting action move the line after it opens.
Most projections use the average, and prop lines track the median. One long play pulls a player's average above his typical game, so the average usually sits above the line.
At -115 on both sides, the book holds 6.52% of the money wagered. At -120, it's 8.33%. A standard -110 spread holds 4.55%.
The book has shaded the price toward the side it expects to win more often, without moving the line. Remove the margin from both sides to see the probability it's using.
Before kickoff they can be. Users set the price, so no margin is built in, and on Novig a single pre-game prop carries no fee. On live trades and parlays, takers pay a fee.
Bettors must be 21 or older in most states. Gamble responsibly: if betting stops being fun, the National Problem Gambling Helpline is 1-800-MY-RESET (1-800-697-3738), and ncpgambling.org has more resources.
