What is a Point Spread?

Point Spread Betting Explained

The point spread is the great equalizer in sports betting. Instead of simply picking who wins, spread betting asks you to predict the margin of victory. A sportsbook sets a number — the spread — that the favorite must win by for a bet on them to pay out. This creates a roughly even proposition on both sides, making every game compelling to bet regardless of the talent gap.

How to Read the Spread

When you see Michigan State -5.5 vs. Wisconsin +5.5, the line means Michigan State is favored by 5.5 points. If you bet Michigan State -5.5, they must win by 6 or more points for your bet to cash. If you bet Wisconsin +5.5, the Badgers can lose by up to 5 points and your bet still wins — or if Wisconsin wins outright, you win regardless.

The half-point (.5) exists specifically to prevent pushes, which we'll cover below.

What Does ATS Mean?

ATS stands for "against the spread" and is the standard way to measure betting performance. A team's ATS record tracks how often they've covered the spread, not just how often they've won. A team can be 20-5 straight up but only 12-13 ATS if they frequently win by fewer points than the spread.

This is exactly why ATS records matter more than win/loss records for bettors. Our results page tracks every pick's ATS outcome — wins, losses, and pushes — because that's what determines profitability.

How Are Spreads Set?

Sportsbooks set opening lines using power ratings, statistical models, and historical data — not unlike what our prediction model does. But here's the key difference: once the line opens, it moves based on betting action. If 80% of the money comes in on one side, the book adjusts the line to balance their risk.

This creates opportunities. Sometimes public perception pushes a line beyond where the statistics justify it. That's where data-driven models can find value — by identifying games where the spread has moved away from the "true" line.

Covering the Spread

A team "covers" the spread when they beat it. If Kansas is -7 and wins 85-75 (by 10 points), Kansas covered. If Kansas wins 80-75 (by 5 points), Kansas did not cover — the underdog covered instead. The key question is always: did the favorite win by more than the spread?

Push Scenarios

A push occurs when the final margin lands exactly on the spread. If the line is Duke -4 and Duke wins by exactly 4 points, the result is a push and all bets are refunded. Sportsbooks use half-point spreads (-4.5 instead of -4) to minimize pushes, but whole-number spreads on key numbers like 3, 7, and 10 still produce pushes regularly.

At SharpBetz, pushes are tracked separately in our results — they don't count as wins or losses in our ATS record.

Why Spread Betting Matters

Spread betting is the bread and butter of sports wagering because it levels the playing field. You don't need to find upset picks to profit — you just need to be right about the margin more often than not. A consistent 55%+ ATS win rate, after accounting for the standard -110 vig, generates long-term profit. That's the benchmark we hold ourselves to.
