Does the Same Parlay Pay More at a Different Sportsbook?

Yes, and the gap grows as you add legs. We built 20,000 four-leg NFL parlays from real DraftKings, FanDuel and BetMGM prices, weeks 1 to 5 of 2026. The book that paid most paid a median 25% more profit than the book that paid least. One book had the best price on every leg only 7.5% of the time.

Same players, same lines, same games. Your chance of winning does not change from one book to the next. Only what the slip pays when it wins.

Comparing your own slip that way is what ET Parlays Slip Shop does: it prices the same parlay at each sportsbook, side by side, before you place it. Below is the research behind it.

One real slip, three prices

Here is a four-leg slip from week 5, one leg from each of four games, at the last prices stored before kickoff. The number next to each leg is what that book would have charged you for it.

DraftKings paid $17.64 more than FanDuel on the same $10 slip. Most of that came from one leg. The touchdown was +245 at DraftKings and +220 at FanDuel, while the three yardage legs were priced between -112 and -115 everywhere.

That slip is on the quiet end. It is three main lines and one touchdown, the prices books watch most closely. Slips with alternate lines and longer prices drew far wider gaps.

Why the gap grows with every leg

A parlay multiplies the price of each leg. So a small difference on each leg multiplies too. Here is the median extra profit at the best of the three books, over the worst, by the number of legs:

Any line: 3,413 player props all three books posted at the same line, priced between -400 and +600. Main lines: the 481 yardage and reception props priced between -140 and -100 at all three. 20,000 slips at each size, every leg from a different game.

The main lines barely move between books, because those are the numbers everyone sees first. Books disagree on alternate lines and touchdowns, and those are the legs that make a slip pay big. The more of them on your slip, the more the book you pick matters.

On a four-leg NFL slip of main lines, the best of three books paid a median 8.7% more than the worst. With alternate lines and touchdowns in the mix, the median gap was 25%.

The best book changes from slip to slip

Across the 20,000 four-leg slips, DraftKings paid most on 52%, FanDuel on 41% and BetMGM on 8%. BetMGM paid least on 79%. These are five weeks of prices on these legs, and books change their prices every day, so read them as a pattern, not a ranking.

The more useful number is this one: one book had the best price on every leg of a four-leg slip only 7.5% of the time. On two legs it was 42%. So the book with the best price on your favorite leg is often not the book that pays most for the slip. And you cannot split a parlay across books. The whole ticket goes at one book, priced leg by leg by that book.

So the only way to know which book pays most for your slip is to price that exact slip at each one. That is the comparison Slip Shop runs for ET Pro members.

What a better price does not do

It does not make your slip more likely to land. Four legs that each land about half the time land together about 6 times in 100, at any book. A better price shrinks the books’ cut on the ticket. It does not remove it, and the cut stacks on every leg you add (the math is in why parlays lose: the vig stacks).

So if your slip is a long shot at the worst price, it is still a long shot at the best one. Dropping a leg moves your chances more than any book can.

Same-game parlays are different

Everything above uses legs from different games. There, a book’s parlay price is its leg prices multiplied, so the comparison is exact. In a same-game parlay each book prices the legs together, because they move together, and every book does that math its own way. The price you see at the book can sit well above or below the legs multiplied. Same-game parlays are not in these numbers (more on how books price them in the SGP tax, explained).

How we measured this

• Prices: the last DraftKings, FanDuel and BetMGM price ET stored before kickoff for each NFL player prop, weeks 1 to 5 of 2026, 77 games. Over or yes side only. Caesars is not in ET’s odds feed, so it is not in the study.
• Legs: 3,413 props all three books posted at the same line, with the three prices fetched within two hours of each other.
• Slips: 20,000 at each size, drawn at random from one week’s legs, every leg from a different game. They are slips we assembled from real prices, not slips anyone placed.
• Not in it: same-game parlays, boosts and promotions, price differences between states, and how prices moved during the week. A slip you build on Wednesday can see different numbers than these.

Compare your own parlay across sportsbooks

Checking four legs at three books by hand is twelve lookups and a calculator. ET Parlays Slip Shop does it for you. You see what your whole slip pays at each book ET links, every leg’s price at every book with the best one marked, and which leg is your weakest. Then it opens the slip at the book you pick. It works on a slip you built in ET, or one you paste or scan from another book. It never builds a slip for you, and it says so when your legs come from the same game.

This is research and education, not betting advice. Bet only what you can afford to lose, keep it 21+, and if it has stopped being fun, there is free help: responsible gambling resources.
