What is a Point Spread?
The point spread is the most popular way to bet on football and basketball. Oddsmakers set a number that represents the expected margin of victory, creating a more balanced betting market.
How It Works
- Favorite (-7): Must win by more than 7 points to cover
- Underdog (+7): Must lose by fewer than 7 points (or win outright) to cover
Example
Chiefs -7 (-110) vs Eagles +7 (-110):
- If Chiefs win 28-17 (by 11), Chiefs cover ✓
- If Chiefs win 24-20 (by 4), Eagles cover ✓
- If Chiefs win 27-20 (by exactly 7), it's a push (tie) and bets are refunded
