Point Spread

A point spread is a figure set by oddsmakers to represent the expected margin of victory between two teams. The favorite carries a negative spread (say, -6.5) and must win by more than that figure for a spread bet on them to cash. The underdog carries a positive spread (say, +6.5) and covers by losing by fewer than that many points – or by winning outright.

The spread exists to make both sides of a contest a roughly equal proposition. Absent a spread, badly lopsided matchups would draw nearly all the action one way. Handicapping the favorite pushes wagering toward balance and lets books manage risk more effectively. Spread bets typically price near -110 per side, so you stake $110 to win $100 whichever team you back.

Example

In an NFL game, the Kansas City Chiefs are favored at -7.5 against the Denver Broncos at +7.5. Bet the Chiefs at -7.5 and they must win by 8 or more for the wager to succeed. A Chiefs win by exactly 7 means the Broncos covered. Bet the Broncos at +7.5 and they can drop the game by as many as 7 and still win your bet – and a Broncos outright win covers as well.

Wager $110 on the Chiefs at -110 and watch them win 31-20 (an 11-point margin), and you collect $100 profit plus your $110 stake back.

Key Points

• Half-point spreads eliminate ties: Spreads ending in .5 (such as -3.5 or +6.5) guarantee a winner and a loser on the spread bet, ruling out a push.
• Key numbers matter in football: In the NFL, margins of 3 and 7 land most often because they map to a field goal and a touchdown. Spreads on or near these figures carry extra weight.
• Odds adjust with the spread: -110 per side is standard, but the price on a spread can drift to -105 or -115 as the book balances action without touching the spread number itself.
• Available across many sports: Point spreads dominate in football and basketball but also appear in baseball (as a run line) and hockey (as a puck line).
