Most professional bettors don't act on a split this size in isolation; they use it as one input among several.

Frequently asked questions

What is sharp money?

Sharp money is wagering activity from sophisticated, high-volume bettors. It shows up as a money percentage that exceeds the bet percentage on the same side. See our learn page for more.

What is a meaningful bet% / money% gap?

A 10-point gap is the threshold we treat as noise vs. signal. 15+ points is meaningful — it usually means the average bet on the money side is materially larger than on the public side.

How often does the team with more money% cover?

In our season-to-date sample, the side with more money than bets covers slightly more than half the time. The edge grows with the size of the bet/money gap.

What does it mean when Chicago Cubs -1.5 has 70% of bets but 60% of money?

When the bet count and the dollars don't agree, the dollars usually carry the sharper signal. A 10pp gap means the average bet on Chicago Cubs -1.5 is smaller than the average bet on the other side.

When does the public usually win?

Public favorites still win plenty of games — they are usually the better team. Where the public underperforms is against the spread on big-name teams in nationally televised games.

What's a meaningful bet/money split?

A 10-point gap between the share of bets and the share of dollars on a side is the threshold we treat as meaningful. 15+ points usually means the average bet on the money side is materially larger — that's where sharp money lives. See our methodology →
