Public (or square) bettors bet for fun. They tend to back popular teams, favorites and overs, and they like parlays.
Sportsbooks make most of their money from recreational bettors, and sometimes shade lines on popular sides because they know the public will bet them anyway.
Betting against the public is called contrarian betting.
How it works
Public bettors are the majority of people who bet. Most bet for fun, on games they're watching, with modest stakes. There's nothing wrong with that, and sportsbooks are built around it.
Public money tends to follow patterns:
- Popular teams and big-market clubs
- The favorite, especially in prime-time games
- Overs, because people enjoy rooting for points
- Long-shot parlays and same game parlays
Because sportsbooks know this, they sometimes shade the price on the popular side a little. In a big game, the favorite might be -7 when the "fair" number is closer to -6.5, because the book expects heavy public betting either way.
"Square" is the slang version and can sound dismissive, but it simply means a recreational bettor. Public betting percentages are published by some sites, but they're often estimates and rarely show how much money is behind each side. That's why bettors who go against the public, known as contrarian betting, treat it as one angle rather than a rule.
Examples
- Example 1
Prime-time favorite. A popular team is playing on national TV and around 80% of bets are on them. The line moves from -6 to -7 even though there's no injury news. Much of that move can come from the sheer volume of public bets.
- Example 2
Parlay habits. A casual bettor puts $10 on a five-leg parlay of favorites every Sunday. It pays well when it hits, but the sportsbook's margin compounds on every leg, which is part of why parlays are so popular with books.
Common questions
What does it mean to bet with the public?
It means backing the side most bettors are on, often a popular favorite or the over. It isn't wrong, but you may be paying a slightly worse price than the fair number.
Are public betting percentages accurate?
Treat them as rough guides. They usually come from a single sportsbook or estimate and often show the number of bets rather than the amount of money.
