What is ATS? Betting Against The Spread Explained
Updated October 1, 2026
Updated October 1, 2026
Against the spread (ATS) is one of the most common terms in sports betting. Instead of betting on which team will simply win the game, an ATS bet is based on whether a team covers the point spread set by the sportsbook.
A favorite must win by more than the spread to cover, while an underdog can either win outright or lose by fewer points than the spread and still cash the bet.
For example, if a team is -7.5, it must win by 8 or more points to cover. If a team is +7.5, it can lose by 7 or fewer points, or win the game outright, and still cover.
Below, we explain what ATS means, how point spread betting works, and what bettors should know before placing a spread wager.
Quick Answer
ATS = Against The Spread
Against the spread betting is about the final margin, not just who wins the game. Use this example to see how favorites, underdogs, covers, and pushes work.
Spread
Cowboys -7.5
Dallas must win by 8 or more points to cover.
Underdog
Eagles +7.5
Philadelphia can win outright or lose by 7 or fewer.
Cowboys win 28-20
Dallas wins by 8, so Cowboys -7.5 covers.
Cowboys win 24-20
Dallas wins by 4, so Eagles +7.5 covers.
Cowboys win by exactly 7
At -7, this would be a push. At -7.5, it loses.
Simple rule: favorites need to win by more than the spread. Underdogs can lose within the spread and still cash.
In sports betting, against the spread (ATS) means wagering on whether a team will cover the sportsbook's point spread, not just whether it will win the game outright.
Push: If the final margin lands exactly on the spread, the bet is refunded.
Favorite: Must win by more than the listed spread to cover.
Underdog: Can lose by fewer points than the spread or win outright to cover.

You will often see point spreads that include a half-point, such as -3.5 or +7.5. In sports betting, this half-point is known as "the hook."
Because it is impossible for a team to score a half-point in basketball or football, the hook guarantees that there will be no ties (pushes). If you bet a -7.5 favorite, they must win by 8 or more. If they win by exactly 7, a -7 bet would push and refund your money, but a -7.5 bet loses.
When researching teams, you will often see two different win-loss records listed: Straight Up (SU) and Against the Spread (ATS). Understanding the difference is crucial for handicapping.
Example: A rebuilding football team might have an abysmal 4-13 SU record. However, because they are constantly listed as massive underdogs (+10 or more) and manage to keep games close, they might boast an excellent 12-5 ATS record. For a spread bettor, how a team performs relative to expectations (ATS) is much more valuable than whether they actually win the game.
Point spreads are not static; they change from the moment they are posted until the game begins. This is called line movement. Sportsbooks move lines for a few primary reasons:
Most standard point spread bets do not pay out evenly. They are typically priced at -110 odds.
This built-in mathematical edge is how sportsbooks make their money, known as the vigorish, vig, or juice. At -110 odds, you must risk $110 to win $100 in profit (or $11 to win $10).
While "against the spread" is primarily used for football and basketball, the exact same mathematical concept applies to other sports under different names:
Most against the spread betting is done in what is called a straight bet. A straight bet is the most common type of bet for betting on the NFL, NBA, College Football & Basketball. It consists of one singular pick against the spread, where a bettor wagers on either the favorite or underdog in one game.
Another way to get involved with ATS betting is to place a parlay wager. With parlays, bettors can make multiple ATS wagers, needing all of them to win for their ticket to cash. Parlays are harder to win than straight bets, as bettors need multiple outcomes to work out in their favor, but they also have the potential to pay out more than straight bets as a result.
NFL ATS Example
Giants -7 vs Cowboys +7
Betting line
New York Giants -7
The Giants must win by 8 or more points to cover.
Final score
Giants
Favorite -7
28
Cowboys
Underdog +7
20
Result: The Giants won by 8 points, so they covered -7. The Cowboys did not cover +7.
NBA ATS Example
Warriors -10 vs Nuggets +10
Betting line
Golden State Warriors -10
The Warriors must win by 11 or more points to cover.
Final score
Warriors
Favorite -10
99
Nuggets
Underdog +10
90
Result: The Warriors won by 9 points, so they failed to cover -10. The Nuggets covered +10.

What does ATS mean in betting?
ATS stands for against the spread. It means a bet is graded based on whether a team covers the point spread set by the sportsbook rather than simply winning the game outright.
What does it mean to cover the spread?
To cover the spread means a team performs well enough relative to the betting line to win the wager. A favorite must win by more than the spread, while an underdog can lose by fewer points than the spread or win outright.
Is ATS betting the same as point spread betting?
Yes. ATS betting and point spread betting mean the same thing. Both refer to wagering on whether a team covers the sportsbook's spread.
What is a push in ATS betting?
A push happens when the final margin lands exactly on the point spread. When that happens, the sportsbook refunds the original stake.
Can a team win the game but fail to cover the spread?
Yes. A favorite can win the game outright but still fail to cover if it does not win by more than the listed spread.
Is it better to bet against the spread or the moneyline?
It depends on your risk tolerance. Moneyline betting is simpler because you only need to pick the winner, but betting on heavy favorites yields very small payouts. ATS betting levels the playing field, offering better payouts on favorites, but adds the difficulty of needing a specific margin of victory.
