What Does Betting Against the Spread Really Mean?

If you’ve ever asked yourself, “what does against the spread mean in betting,” you’re not alone. Betting against the spread (often shortened to ATS) is one of the most widely used terms in sports betting, yet it often causes confusion – especially for those new to handicapping. At its core, betting ATS shifts the focus from simply picking winners to evaluating margins of victory. In this article, we’ll explain exactly what the spread is, how it works, walk through real-world examples, and explore the thought process behind ATS strategies. Whether you’re just starting out or looking to sharpen your edge, understanding this concept is critical for long-term success.

What Does “Against the Spread” Mean?

Betting against the spread means you’re not just choosing which team will win, but rather whether a team will cover a set margin of points – the spread – established by oddsmakers. This number is designed to make both sides of a matchup equally attractive to bettors.

The favorite must win by more than the spread for a bet on them to cash. The underdog must either win outright or lose by fewer points than the spread to win the wager. It’s not about who wins the game; it’s about who covers the number.

So, when people ask what does against the spread mean in betting, the short answer is: you’re betting on performance relative to the point spread, not just the scoreboard.

What Is the Point Spread?

The point spread is a handicap applied to a game to level the playing field. It’s a prediction of how much one team will beat another by, set by sportsbooks to encourage balanced action on both sides.

For example:

• New England Patriots -5.5
• New York Jets +5.5

If you bet the Patriots, they need to win by 6 or more for your bet to win. If you bet the Jets, they can lose by 5 or fewer, or win the game outright, and your bet wins.

The .5 on the spread is called a “hook,” and it eliminates the possibility of a push (a tie where your bet is refunded).

A Real-World Example of ATS

Let’s say the Kansas City Chiefs are playing the Las Vegas Raiders. The line is set at:

• Chiefs -7
• Raiders +7
• If the Chiefs win 28–20, they cover the spread, and a bet on Kansas City wins.
• If the Chiefs win 24–20, they win the game, but don’t cover, and a bet on the Raiders wins.
• If the game ends 27–20, it’s a push, and your bet is refunded.

This example highlights the key takeaway: you can bet on a losing team and still win, or bet on a winning team and lose, depending on how the score compares to the spread.

Why Do Sportsbooks Use Spreads?

The spread isn’t just for balance – it adds complexity and forces bettors to think deeper. If every bet was a simple moneyline pick, public favorites would dominate wagering and open sportsbooks to massive liabilities.

Here’s what spreads accomplish:

• They balance betting action by making underdogs more attractive.
• They reduce risk for sportsbooks, helping them manage exposure.
• They create more engaging betting markets, especially in mismatched games.

For bettors, the spread creates opportunities to find value – particularly when public opinion drives the line away from what the data suggests.

Thinking in Terms of ATS

Successful handicappers often track team performance against the spread, not just win/loss records. Some teams consistently overperform relative to expectations and “beat the number,” even if they don’t win many games. Others underperform despite winning.

That’s why you’ll hear terms like:

• “Team X is 7-3 ATS this season”
• “Team Y hasn’t covered in four straight games”

These stats can tell you how well a team is doing compared to what oddsmakers expected, which can be more informative than looking at standings.

Building a Strategy Around ATS Betting

Once you understand how the spread works, you can begin developing a strategy to approach ATS bets more systematically.

Key Traits of an ATS Strategy:

• Focus on value, not favorites. Sometimes the public drives up a favorite’s line and creates an edge on the underdog.
• Study line movement. If a spread moves significantly, there may be key news or sharp money involved.
• Analyze situational angles like travel, injuries, weather, and short weeks.
• Track team ATS trends. Some teams historically perform better in certain spots (e.g., road underdogs, divisional games).

Popular ATS Strategies (Backtesting Recommended)

Here are a few angles bettors explore when betting against the spread. These are not guaranteed to be profitable and have not been backtested for this article. Always test any strategy with past data before wagering real money.

1. Fade the Public – When most bets are coming in on one side, some bettors look to take the opposite, especially when the line has moved significantly in that direction. This approach assumes that sportsbooks shade the line to capitalize on public bias.

2. Bet Underdogs in Divisional Games – Divisional matchups tend to be tighter due to familiarity. Underdogs often perform better ATS in these games because teams know each other well, and games are harder to blow out.

3. Focus on Key Numbers – In football, 3 and 7 are key margins of victory. Betting -2.5 or +3.5 can provide a real edge over -3 or +3, especially when betting late or early depending on the line movement.

4. Road Underdogs After a Blowout – Some bettors look for underdogs coming off big losses, especially if they’re playing on the road the next week. The public often overreacts, creating value.

Final Thoughts

To close it out, what does against the spread mean in betting? It means you’re not just betting on who wins – you’re betting on whether a team meets or exceeds the expectations set by the oddsmakers. The spread adds complexity, strategy, and opportunity to the betting process. And while ATS betting requires deeper analysis and discipline, it also opens the door to smarter wagers and more consistent returns over time.

Understanding the spread is a must for serious bettors. With knowledge, testing, and a strategy you trust, betting ATS can become a core part of your sports betting success.
