What Does -3.5 Mean in Betting

The number -3.5 represents a point spread assigned to the favorite team. The minus sign shows which team sportsbooks expect to win.

Why Sportsbooks Use the -3.5 Spread

The -3.5 line
Creates a clear winner and loser
Balances betting action on both sides

How the -3.5 Spread Works in Practice

When you place a bet on a team at -3.5, the sportsbook subtracts 3.5 points from that team’s final score.

After the adjustment, the sportsbook compares the scores again to determine the winner.

Example of -3.5 in Football Betting

Team A is favored at -3.5 against Team B.

Final score
Team A 27
Team B 23

Team A wins by 4 points, so the -3.5 bet wins.

If the score were 27 to 24, Team A would only win by 3 points, and the bet would lose.

Example of -3.5 in Basketball Betting

Team X is listed at -3.5.

Final score
Team X 112
Team Y 109

Team X wins by 3 points, so the bet loses.

The team needed to win by 4 or more points.

Difference Between -3 and -3.5

The difference between these two lines matters a lot.

-3 allows for a push if the team wins by exactly 3
-3.5 removes the push and forces a win or loss

Many bettors prefer half point spreads because they avoid refunds.

What the Minus Sign Means in Betting

The minus sign always identifies the favorite. The higher the number, the stronger the favorite.

For example
-1.5 slight favorite
-3.5 moderate favorite
-7.5 strong favorite

What Happens If the Favorite Loses

If the team at -3.5 loses the game outright, the bet automatically loses.

The favorite must win by the required margin for the bet to succeed.

Betting the Underdog at +3.5

When you bet the underdog at +3.5, that team can
Win the game
Lose by 3 points or fewer

In both cases, the +3.5 bet wins.
