Quick answer: The three core NFL markets are the spread (a points handicap that levels two unevenly matched teams), the moneyline (a straight bet on who wins outright), and the total (over/under on combined points scored by both teams). Nearly every other NFL market is a variation or combination of these three.
The Spread: Betting the Margin, Not Just the Winner
The spread assigns a points handicap to each side so that a heavy favourite and a clear underdog can be bet at roughly even odds. A team listed at -6.5 must win by 7 points or more for a spread bet on them to pay out; the underdog at +6.5 covers by either winning outright or losing by 6 points or fewer. The half-point (the “hook”) exists specifically to eliminate ties — called a “push” — on spreads that would otherwise land on a whole number.
Because NFL scoring moves in specific increments — 3 points for a field goal, 6 for a touchdown before the extra point — certain spread numbers come up far more often than others. Games routinely land on margins of exactly 3 or 7 points, which is why spreads clustered around those numbers (2.5, 3.5, 6.5, 7.5) tend to move more sharply than a spread sitting at, say, 9.5.
The Moneyline: Just Pick the Winner
The moneyline strips out the margin entirely — you are betting only on who wins the game. Because it carries no handicap, the odds themselves do all the work of balancing the two sides: a heavy favourite pays out at short odds, while backing the underdog outright pays significantly more given the larger risk.
Moneyline bets are usually the simpler choice for a genuine mismatch, where the spread number might require covering by an uncomfortably large margin. For a closely matched game, the spread and moneyline can end up implying similar prices, and the choice becomes a matter of preferring a bigger payout (moneyline underdog) against a safer, smaller-margin cover (spread).
Totals: Betting the Combined Score
The total, or over/under, sets a number for the combined points scored by both teams, and you bet whether the actual combined score lands over or under it. It has nothing to do with which team wins — a 31-28 shootout and a 6-3 defensive grind produce very different total outcomes despite one arbitrary margin of victory being similar in each case.
Totals are driven heavily by pace of play, offensive scheme, weather, and the health of key offensive players, which is why a total can move several points between the opening line and kickoff based on injury news or a forecast update alone.
How the Three Markets Relate
| Market | What you’re betting on | Best suited for |
|---|---|---|
| Spread | Margin of victory against a handicap | Closely or moderately matched games |
| Moneyline | Outright winner, no handicap | Clear mismatches, or wanting underdog value |
| Total | Combined points scored by both teams | Games where pace or weather matters more than the matchup |
Reading the Odds Format
All three markets are priced using the same moneyline-style odds regardless of bet type — a negative number shows how much you must stake to win 100 units, a positive number shows how much a 100-unit stake would return. If you need a refresher on converting between formats, our guide to reading sports betting odds covers decimal, fractional and moneyline notation side by side.
Why Lines Move Before Kickoff
Spreads, moneylines and totals all move in response to two forces: new information (an injury report, a weather forecast, a lineup change) and the balance of money being wagered on each side. A sportsbook adjusts a line to manage its own risk exposure, not to predict the final score — which is why chasing a number that has already moved significantly can mean paying a worse price for the same bet than was available earlier in the week.
Frequently Asked Questions
What does it mean when a spread has a half-point?
The half-point removes the possibility of a push (a tie against the spread) by making an exact-margin outcome impossible. A whole-number spread can push and return all stakes; a half-point spread always resolves as a win or a loss.
Can I combine a spread and a total on the same game?
Yes — most operators let you combine markets from the same game into a same-game parlay, though this usually reduces the combined odds compared to betting each market separately, since the outcomes are not fully independent.
Why do moneyline underdogs sometimes offer huge payouts?
The payout reflects how unlikely the sportsbook considers that outcome. A large underdog price is simply the odds format expressing a low implied probability — it carries no special insight beyond what the spread for the same game already tells you.
Is the moneyline always a worse bet than the spread for a favourite?
Not always, but a heavy favourite’s moneyline is usually priced short enough that the spread, if you’re confident in a large margin of victory, often offers better relative value than laying a big moneyline price to win a small amount.
