What is the vig on DraftKings player props?
Short answer: The vig on a DraftKings player prop is the amount the over and under prices imply above 100%, and on two-way props it is usually several percentage points. On player props Pinnacle's margin is similar, which is why Pinnacle's value as a reference comes from how it prices and moves, not from a lower margin. Today's medians for both books are measured on this page.
How to measure it
Add the implied probabilities of the over and the under. Over -115 implies 53.5%, under -105 implies 51.2%; together 104.7%. The vig on that prop is 4.7 percentage points. (Conversion steps: how to calculate a no-vig price.)

Why Pinnacle's prop margin is not lower
Pinnacle is known for low margins on main markets, but player props are smaller, harder-to-price markets and its margins there are similar to DraftKings'. Pinnacle's usefulness as a reference on props comes from how its prices respond to informed money (see sharper book), not from charging less.
Why the vig matters
The margin is what you pay to bet. Two books can disagree about the probability and charge different margins at the same time; comparing no-vig probabilities separates the two. Both books' prices for tonight's lines are on the props page.
Vig on parlays and same-game parlays
Every leg of a parlay carries its own margin, and the margins multiply. A two-leg parlay of props each carrying several points of vig costs more than the same two bets placed straight; a five-leg same-game parlay costs much more. The parlay guide works through the arithmetic.
Reducing what you pay
- Compare prices across books; the same line can carry a different margin elsewhere.
- Prefer the side of a market where the price is closest to fair; the margin is not always split evenly.
- Be wary of boosted or promotional prices that change the line or limit the stake; the headline price is not the whole cost.
Why props carry more vig than main markets
Player props are harder to price than point spreads and totals, have lower betting limits, and attract less of the professional money that keeps main markets tight. Books protect themselves on these markets with a wider margin. That is true at DraftKings and, as the figures above show, at Pinnacle as well: the margin you pay on props is higher than the familiar -110 on both sides of a main-market spread.
