Prop Bets
Bets on what happens inside the game.
Example numbers — made up for illustration, not real lines
Proposition bets — "props" — are wagers on specific events inside a game rather than the final result. Will a quarterback throw for more than 245.5 yards? Will a star score 30 points? Will there be a score in the first five minutes? Props have become one of the fastest-growing parts of U.S. sports betting, in large part because they let fans bet on the players they follow.
Player props
The most common props are over/unders on individual statistics. Examples: a running back over/under 72.5 rushing yards; a point guard over/under 8.5 assists; a pitcher over/under 6.5 strikeouts; a hockey player to score a goal (often called an "anytime goal scorer" bet). These are priced like totals, usually with plus or minus odds on each side.
Game props
Game props focus on events rather than individual players: first team to score, whether a game goes to overtime, the longest touchdown, the method of the first score, or whether both teams score in soccer. Some are straightforward; others are closer to novelty bets.
Novelty props and the Super Bowl
The Super Bowl is famous for its long menu of props. Many legal sportsbooks offer dozens or hundreds of markets on the game. State regulators decide what's allowed, and many states prohibit betting on non-sporting events like commercials or halftime shows. What you see depends on where you are.
Why props are different
- Margins can be higher. Props are harder to price precisely, and books often protect themselves with wider margins and lower limits.
- Player availability matters. If a player doesn't play, prop bets are usually voided, but the rules for players who leave early vary.
- Correlation. Props connect to each other — a quarterback's passing yards and his receiver's yards move together. That's why books price same-game combinations carefully (see parlays).
College props
Many states restrict proposition bets on college athletes because of concerns about integrity and harassment of student-athletes. Other states have similar or narrower rules, and the list has been changing. Check your state regulator's current rules.
A word on integrity and conduct
Prop betting has drawn public attention because of incidents of athletes and staff being harassed over individual stats, and because of integrity investigations in several leagues. Leagues and regulators have responded with monitoring and rule changes. If you bet props, remember that the players are people. Never message or harass anyone over a bet.
Using props as a fan
Props are a fun way to follow individual performances, especially in games where you don't care who wins. Keep stakes small, understand that the numbers are carefully set, and remember that individual stats are highly variable. A great player can have a quiet night for reasons nobody could predict.
Worked example
Example: a receiver's yardage prop is set at 64.5, over -115 / under -105. The slightly higher price on the over suggests the book expects a bit more action, or a slightly higher median, on that side. If the receiver catches a 70-yard touchdown on the first drive and then leaves with an injury, the over wins under most books' rules because he played. If he doesn't play at all, the bet is typically voided. Read the house rules for your book.
Common mistakes
- Assuming averages predict a single game. Player stats are highly variable.
- Overloading same-game parlays with correlated props.
