Parlay and Teaser Hold Rates at US Sportsbooks Explained
Parlays and teasers carry far higher hold percentages than single-game bets. Here's the math every US bettor needs before placing multi-leg wagers.
Parlays and teasers are profit centers for sportsbooks. The hold on a standard single-game spread bet runs about 4.77% at -110 on both sides. Stack three or four legs together and that margin compounds fast. Before you build another parlay slip, understand what you're actually giving up.
How does hold percentage work on a single-game bet?
Hold is the sportsbook's built-in edge. Sum the implied probabilities of every outcome on a market and the total exceeds 100%. That excess is the hold. At standard -110 on both sides, each side carries an implied probability of roughly 52.38%. Add them: ~104.77%. Hold = 4.77%, RTP = ~95.23%. A market priced at -190 and +260 produces implied probabilities of ~65.52% and ~38.46%, combining to ~103.98% — a hold of about 3.98%. Lower holds are better for bettors. That's why reduced-juice lines (-108 instead of -110) matter over a long season.
Why are parlay and teaser holds so much higher?
Every time you add a leg, the sportsbook's margin compounds. You're not just absorbing one 4.77% edge — you're absorbing it multiplied across each leg. Teasers move point spreads in your favor, but the sportsbook reduces the payout odds to compensate; the adjusted lines still carry vig, and that vig multiplies across legs just like a standard parlay. Futures markets work the same way at an even uglier scale: a Super Bowl outright winner market carries dramatically higher hold percentages than spread or moneyline bets because of the larger number of outcomes. There's also a consistent downward trend in RTP as odds increase — higher-odds wagers promise bigger payouts, but statistical value relative to the stake diminishes. That's the trap parlays set.
How do the major bet types compare on hold?
| Bet Type | Typical Odds / Structure | Approximate Hold | RTP |
|---|---|---|---|
| Single-game spread (standard) | -110 / -110 | ~4.77% | ~95.23% |
| Single-game spread (reduced juice) | -108 / -108 | ~3.70% | ~96.30% |
| Moneyline (heavy favorite / underdog) | -190 / +260 example | ~3.98% | ~96.02% |
| Futures (e.g., Super Bowl winner) | Multiple outcomes; odds vary widely | Dramatically higher than spread markets | Materially lower than single-game bets |
| Parlay (multi-leg) | Compounded across legs | Increases with each leg added | Declines with each leg added |
Does it matter which sportsbook I use for parlays?
Yes, and significantly. Operators that offer reduced juice on individual legs lower the compounded hold on parlays built from those legs. Heritage Sports, for example, offers -108 on major sports markets instead of the standard -110 — that difference compounds favorably across a multi-leg ticket. US legal sports betting handle reached nearly $150 billion in 2024, and hold-percentage data from state regulatory filings confirms real differences between operators.

What other high-hold bet types should I watch out for?
Parlays and teasers aren't the only landmines. Prop bets, live betting markets, and certain exotic wagers also carry elevated holds. I've tracked this for years at the window — the same principle applies whether you're betting horses or football. See the full breakdown at High-Hold Bets US Sportsbooks Don't Want You to Know About.
What should I check before claiming a bonus on parlays?
Many welcome offers restrict bonus bets to minimum odds per leg or exclude certain bet types entirely. Rollover requirements can force you into higher-hold markets just to clear the bonus.
