What is Prop Bet in Sports Betting?

2 min readUpdated Feb 2026

Definition

A prop bet, short for proposition bet, is a wager on a specific event or statistical outcome within a game rather than the final result. Props can focus on individual player performances, team statistics, or game events like who scores first. Prop betting has exploded in popularity with the rise of same-game parlays and represents the fastest-growing segment of sports betting.

Prop Bet Explained in Detail

Prop bets come in two main categories: player props and game props. Player props focus on individual statistics like passing yards, rushing yards, rebounds, goals, or strikeouts. Game props focus on team or game events like which team scores first, whether the game goes to overtime, or the exact final score.

The rise of prop betting has been driven by several factors. First, they make every moment of a game exciting because your bet can be decided at any point. Second, they allow bettors to use specialized knowledge about specific players or situations. Third, they are the building blocks of same-game parlays, which sportsbooks heavily promote.

Player props are where sharp bettors often find the most value. Sportsbooks have decades of data and sophisticated models for game outcomes, but player prop markets are newer and less refined. A bettor who closely follows a specific team might notice that a running back is due for a bigger workload or that a pitcher struggles against left-handed lineups before the sportsbook adjusts.

The key to profitable prop betting is finding inefficiencies. Sportsbooks set hundreds of props per game, and they cannot dedicate equal attention to every line. Less popular props on lesser-known players tend to have softer lines. Bettors who do their homework and build their own models for player projections can consistently find edges in the prop market.

Prop Bet Examples

1

Patrick Mahomes over/under 285.5 passing yards is a player prop. If Mahomes throws for 300 yards, the over cashes. If he throws for 270 yards, the under wins.

2

Will there be a score in the first 5 minutes of the game? Yes pays +120, No pays -150. This is a game prop because it focuses on a game event rather than a specific player.
