point spread, spread, line, against the spread (ATS)
Typical price
about -110 odds ($11 risked to win $10)13

Key points

  • The spread is a handicap number set by the sportsbook, not a prediction of the final score.4
  • The favorite gives points and the underdog receives points; the bet wins or loses after that adjustment is applied to the final score.12
  • Most common in sports betting on football and basketball, where it balances the wager between two sides.12
