What is a point spread?

A point spread is a bet on the margin of the game rather than the outcome alone. The favorite gives points (Eagles −3.5 must win by 4 or more); the underdog gets them (Cowboys +3.5 wins the bet by winning outright or losing by 3 or fewer).

Half-point lines can't land exactly, so there is no push; whole-number lines can push, returning the stake.

Worked example

Spread prices cluster near -110: a $100.00 stake at -110 returns $190.91 in total — $90.91 of profit. The implied probability restated from that quote is 52.4%.

How a prediction market handles it

Sportsbooks price both sides of the spread with the margin built in, and move the line itself as money arrives.

Most prediction markets in our coverage don't offer a direct spread equivalent. Event contracts are typically limited to the game outcome and futures-style questions, so for spreads the comparison is usually sportsbook-only.
