The opening line is the first set of odds released by a bookmaker for a sporting event.

It represents the bookmaker’s initial pricing before public and sharp money enter the market.

How it works

• Odds are published days or weeks before the event

• Early bettors influence how the line moves

• Opening lines are often softer than closing lines

Example

• Opening odds: 2.30

• Heavy betting on one side

• Closing odds: 1.95

Key characteristics

• Important reference point for line movement

• Targeted by sharp bettors looking for early value

• Sets the foundation for the entire betting market

Important note
Beating the opening line is less important than beating the closing line, but early value often disappears quickly.
