Prop betting focuses on player or team outcomes—like passing yards, shots on goal, or strikeouts—rather than the final score. Props can be softer than main markets, but they’re more news-sensitive and often carry higher hold. This guide explains types of props, how books price them, timing, examples, and common mistakes. For a neutral primer, see Wikipedia: Proposition bets.
What Is a Prop Bet?
A prop (proposition) bet is a wager on a specific outcome inside the game—player or team—rather than who wins. Props can be offered pregame and live/in-game.
Common Prop Types
- Player counting stats: NFL passing/rushing/receiving yards; NBA points/rebounds/assists; NHL shots; MLB strikeouts/total bases.
- Team props: Team totals, first to X points, first period/quarter/inning scoring.
- Milestones & ladders: Tiered alt lines (e.g., 25+, 30+, 35+ points) with escalating prices.
- Yes/No events: Anytime touchdown scorer, to record a hit, to make 3+ threes.
- Same-Game Parlays (SGP): Props combined within one game with correlation priced in by the book.
How Props Are Priced (and Why They Move)
- Projections: Books start from per-minute/usage/efficiency models (pace, matchup, role).
- News sensitivity: Role changes (starter → bench), minutes limits, injuries, weather (NFL/MLB) can swing numbers quickly.
- Hold/limits: Props usually have higher hold and lower limits than sides/totals—shop aggressively.
Timing: When to Bet Props
- Early (if you have info): Beat market before role/minutes news is widely priced in.
- After confirmations: When lineups, snap counts, goalie/pitcher status are official, misprices can still exist across books.
- Live/in-game: Prop menus thin out, but pace and role changes can create edges if you’re fast. See Live / In-Game Betting.
Shopping Prop Lines
- Compare 3–5 books: A 0.5 rebound or 2.5 yards difference is meaningful—and prices vary.
- Check alt lines: Ladders sometimes offer better risk/reward than standard lines if your edge is large.
- Mind the juice: Prop holds are higher; -125 vs -110 matters. See Vig and Juice Explained and How to Shop Betting Lines.
Sport-Specific Angles
- NFL: Snap share, target share, routes run, opponent coverage tendencies, weather (wind/rain).
- NBA: Minutes and usage dominate; pace, foul risk, blowout risk, back-to-backs.
- MLB: Starting pitcher vs lineup K%/BB%, pitch counts, weather, umpire tendencies (where available).
- NHL: Line combos, PP/PK roles, shot volume vs quality, opponent shot suppression.
Examples
NBA Points Prop Example
Player’s season avg 22.0 PPG; teammate sits, usage +4%. Pace up opponent. Books post 21.5 (-120). If your projection is 24.1, either standard Over or an alt ladder (25+ at + odds) can be justified—shop both.
NFL Receiving Yards Example
Wind forecast drops explosives; defense funnels short throws. Book at 59.5 (-110). You project 52.3 → Under or alt Under (50.5 at plus money) depending on distribution.
MLB Strikeouts Example
Starter with 27% K vs high-K lineup, neutral weather, generous ump. Line 6.5 (+115). Your projection 7.1 suggests small Over; compare books and consider 7+ at a better price.
Bankroll & Risk Management
- Small units: 0.5–1.0% per prop; props have higher variance and hold.
- Diversify across markets: Don’t stack too many correlated props (team total Over + multiple player Overs).
- Track CLV analog: Record your line vs the closing consensus to evaluate process quality. See CLV & Line Movement.
Common Mistakes
- Betting without role clarity: Minutes/snap count changes destroy edges.
- Chasing steam: If the move happened, look for buyback or pass.
- Ignoring correlation: SGP legs are priced for correlation—don’t expect “true odds.”
- Forgetting hold: Prop markets can be expensive; line shop or skip.
FAQs: Prop Betting
Are props harder or easier than sides/totals? They can be easier if you track news/roles closely—but holds are higher and lines move fast.
What’s a good unit size for props? Many bettors use 0.5–1.0% per prop, smaller for ladders/SGPs due to variance.
Do books limit winning prop bettors? Some do faster than for sides/totals because props are more exploitable.
