What does hold mean in sports betting?
The hold is the sportsbook’s term for profit. The result is all from a sportsbook’s point of view. A positive number is a positive hold percentage for the sportsbook assuming balanced wagers on both lines. If your input generates a negative number, this means the sportsbook expects to lose money because a negative for the sportsbook is a positive for the bettor. It’ll show in green.
For a bettor, why does hold matter?
Hold matters because the lower the hold, the less you’ll lose when you’re wrong. Finding the best price across sportsbooks is called line shopping. And using the best prices you find on either side of a line creates the lowest possible synthetic hold. The lower the synthetic hold the less of an edge the sportsbooks have over the bettor, regardless of bettor skill.
