Two prices, one game
A moneyline price answers who wins. A spread price answers whether the favorite covers the posted margin, which on a close game is a much narrower question. Pinnacle has Bills at Texans, kickoff Sunday, Sep 13 at 1:00 PM ET, with the Texans getting 1 point at -115, and a moneyline of -108 Texans and -104 Bills. DraftKings has the same game with the Texans favored by 1.5 at +102, and a moneyline of -110 on each side.
The two books disagree about which team is favored. Pinnacle has the Bills laying 1 point. DraftKings has the Texans laying 1.5. Both quotes are live on the same game.
Converting the spread price and the moneyline separately
Pinnacle's Texans spread price of -115 converts the negative-price way, 115 divided by 115 plus 100, which is 53.49%. Pinnacle's Texans moneyline of -108 converts to 108 divided by 108 plus 100, or 51.92%. Those land near each other, 53.49% against 51.92%, because the game is near even on both markets at that book.
DraftKings' Texans spread price of +102 takes the positive-price form, 100 divided by 102 plus 100, or 49.50%. Its Texans moneyline of -110 converts to 110 divided by 110 plus 100, or 52.38%. Those two sit within three points of each other as well. A near-even spread and a near-even moneyline are describing the same thing, a game with little between the teams, whichever side a book calls the favorite.
A game where the two prices are not close at all
DraftKings prices Cardinals at Chargers, kickoff Sunday, Sep 13 at 4:25 PM ET, with the Chargers laying 10 at a spread price of -105. That converts to 105 divided by 105 plus 100, or 51.22%. The Chargers' moneyline on the same board is -500, which converts to 500 divided by 500 plus 100, or 83.33%. Same game, same book, and the two converted numbers stand 32.11 points apart.
They measure different bets. Covering 10 points is nearly even money. Winning the game outright is nowhere near it.
| Game | Book | Market | Price | Implied probability |
|---|---|---|---|---|
| Buffalo at Houston | Pinnacle | Spread (Texans +1) | -115 | 53.49% |
| Buffalo at Houston | Pinnacle | Moneyline (Texans) | -108 | 51.92% |
| Buffalo at Houston | DraftKings | Spread (Texans -1.5) | +102 | 49.50% |
| Buffalo at Houston | DraftKings | Moneyline (Texans) | -110 | 52.38% |
| Arizona at LA Chargers | DraftKings | Spread (Chargers -10) | -105 | 51.22% |
| Arizona at LA Chargers | DraftKings | Moneyline (Chargers) | -500 | 83.33% |
Why the gap between the two changes by game
Bills at Texans is tight enough on both markets that the two converted numbers come out within a few points. Covering a 1-to-1.5-point margin and winning outright are almost the same question when the teams are level. Cardinals at Chargers is not tight. Covering 10 points and winning outright are separate questions there, and the converted numbers land 32.11 points apart.
The gap tracks the size of the spread. A 1-to-1.5-point game makes a small one. A 10-point game makes a large one.
Put either price into the odds converter and you get back a correct implied chance every time. The mistake to watch for is reading a converted spread price as though it answered the moneyline's question. Neither market is more real than the other. Neither percentage is wrong.
They are correct answers to two different questions about one game. If you want a check on your own arithmetic, convert both sides of one market and see whether the pair sums past 100%. When it does not, one of the two prices went in wrong.
Both markets for every Week 1 game sit on the live odds board. A companion explainer on spread betting takes the point-margin market on its own terms, and one on moneyline strategy does the same for winning outright. Every price quoted here is pregame and live. A price that has moved since Sep 7 converts to a different number, and the arithmetic on it does not change.

Pinnacle and DraftKings boards, pulled Sep 7, 2026. On every game we checked, the two converted prices come together when the spread is small and pull apart when it is large. Watch any game whose spread moves more than a point before Sunday's kickoff, then run the comparison again.
