How does betting against the spread work?

The sportsbook sets a point spread to equalize wagering on both sides. The favorite gives points (shown as -7) and the underdog receives points (+7). You win an ATS bet if the team you picked outperforms their spread number, regardless of who wins the game.

What is a good ATS win rate in sports betting?

Because ATS bets are typically priced at -110 (pay $110 to win $100), you need to win at least 52.4% of bets to break even against the vig. A sustained 55% win rate is considered strong. Professional sports bettors operating at 58–60% ATS are in rare company.

What is a push in ATS betting?

A push occurs when the final margin exactly equals the spread (e.g., -7 and the team wins by exactly 7). In a push, your original wager is refunded. No win, no loss. Sportsbooks use half-point spreads (.5) specifically to eliminate pushes.

How does The Lab approach ATS picks differently from moneyline picks?

ATS picks require the model to project not just who wins, but by how much. The model's projected margin is compared to the spread line. Moneyline picks only require projecting a winner. The Lab uses both markets depending on where the edge is stronger for a given game.

Q: What does ATS mean in sports betting?

ATS stands for Against The Spread. Instead of betting on which team wins outright, you bet on whether a team covers a point spread set by the sportsbook. For example, if a team is -7.5 and wins by 10, they covered the spread. If they win by 6, they did not cover.

What Does ATS Mean in Sports Betting?

If you’ve ever scrolled through sports betting Twitter or tuned into a pregame show, you’ve probably heard someone say, “They’re 8-2 ATS this season.” And if you’re newer to the game, you probably nodded along while secretly thinking… what does ATS actually mean?

Don’t worry — Donnie’s got you. Let’s break it down from the ground up so you never feel lost again.

ATS stands for “Against The Spread.” It’s one of the most fundamental concepts in sports betting, and understanding it is the first step toward making smarter wagers.

Understanding the Point Spread

Before we talk ATS, we need to talk about the point spread — also called “the line” or just “the spread.”

The point spread is a number set by oddsmakers to level the playing field between two teams. The favorite gets a negative number (they need to win by more than that), and the underdog gets a positive number (they can lose by less than that and still “cover”).

Here’s a quick example:

Kansas City Chiefs -7.5 vs. Denver Broncos +7.5

This means the Chiefs are 7.5-point favorites. For a bet on the Chiefs to cover the spread, they need to win by 8 or more points. If you bet on the Broncos +7.5, they can lose by up to 7 points, and your bet still wins.

What Does “Covering the Spread” Mean?

When a team covers, it means they performed better than the spread predicted:

If the Chiefs are -7.5 and win 31-20 (by 11), they covered. ✅
If the Chiefs win 24-21 (by 3), they did NOT cover. The Broncos +7.5 covered instead. ❌
If the Broncos lose 17-20 (by 3), Broncos +7.5 bettors win. ✅

The half-point (the “.5”) exists to prevent a push — a tie against the spread where bettors get their money back. With a whole number spread like -7, a 7-point win is a push.

What Is an ATS Record?

An ATS record tracks how a team performs against the spread over a period of time — not just whether they win or lose outright.

For example, a team might be 10-4 on the season (straight up wins and losses) but only 6-8 ATS. Why? Because they’re winning games, but not by enough to cover inflated spreads.

This is extremely common with popular teams. The public loves betting favorites, which drives the line higher, making it harder to cover. Smart bettors know that a team’s ATS record often tells a very different story than their win-loss record.

Why ATS Records Matter More Than You Think

Here’s where it gets interesting. ATS records reveal value.

Consider two teams:

Team A: 12-2 straight up, but 7-7 ATS
Team B: 8-6 straight up, but 11-3 ATS

If you’re betting spreads, Team B is the better bet historically, even though Team A has a better record. Team B consistently outperforms expectations. That’s where the money is.

ATS Betting Tips for Beginners

Now that you understand the basics, here are some quick tips to get you started:

1. Don’t Just Bet Favorites

Public money floods toward favorites, inflating spreads. Underdogs cover more often than most people think. In the NFL, underdogs historically cover around 52-53% of the time.

2. Check ATS Records in Specific Situations

Teams perform differently ATS at home vs. away, as favorites vs. underdogs, and in divisional matchups. The more specific your research, the sharper your edge.

3. Watch for Line Movement

If a line moves from -6.5 to -7.5, that tells you sharp money (professional bettors) is coming in on the favorite. Understanding why lines move is a skill that separates winners from losers.

4. Track Your Own ATS Bets

Keep a record. Know your win rate. If you’re not tracking, you’re guessing — and guessing is how bankrolls disappear.

5. Use Data, Not Gut Feelings

The best ATS bettors rely on models, trends, and analytics — not hunches. That’s exactly what we built The Lab for.
