Parlays are one of the most popular and enticing forms of sports betting, offering the chance to turn a small stake into a big payday. But while the potential payout is high, so is the risk.
Let’s break down how parlays work, how odds are structured, and whether they’re a smart bet long-term — especially across different sports like football and baseball.
What Is a Parlay?
A parlay bet is a single wager that combines two or more individual bets. In order to win the parlay, every leg must win. If even one selection loses, the entire parlay is a loss. This high-risk, high-reward structure is what draws so many bettors to parlays.
Standard Parlay Odds:
How They’re Calculated
In a traditional sportsbook, if all legs of a parlay are -110 (typical odds for point spread or totals bets), the payout is based on a fixed multiplier scale:
But here’s the catch:
these payouts are lower than the true odds would be if calculated independently. The sportsbook holds an implied edge, meaning you’re not being paid fairly for the risk you’re taking.
Parlays in Football: Forced Odds and Payout Manipulation
When you bet parlays in NFL or college football, you’re often taking multiple point spreads or totals, most of which are listed at -110 odds.
While betting three individual -110 bets should yield a true parlay payout of ~6.98 to 1, sportsbooks typically pay ~5.96 to 1.
That’s a built-in disadvantage.
🔍 Example:
If you bet:
Eagles -3 (-110)
Chiefs -6.5 (-110)
Bengals over 47.5 (-110)
Instead of getting ~7x your money, your bookmaker may only pay you ~6x. That’s a house edge baked into every combo.
Parlays in MLB:
True Value on the Moneyline
In contrast, baseball parlays can offer better value — especially when using moneyline odds instead of fixed spreads.
With moneyline bets, the odds vary — and therefore the parlay payout is calculated by multiplying the decimal odds of each leg.
🔍 Example:
Yankees -130 → decimal = 1.77
Dodgers +105 → decimal = 2.05
Braves -115 → decimal = 1.87
Parlay payout:
1.77 × 2.05 × 1.87 = 6.78 to 1 payout
That’s true odds — no fixed multiplier. You’re rewarded exactly for the risk you’re taking, which makes MLB parlays more appealing for sharp bettors.
Should You Bet Parlays? Good Idea or Bad Long-Term?
Parlays offer huge appeal, but they’re also notoriously hard to beat consistently. Most casual bettors lose money on parlays because:
All legs must win, which is statistically unlikely.
Fixed payout tables in sports like football undervalue the true odds. Bookmakers love parlays because of the built-in house edge.
✅ When parlays can make sense:
You’re betting moneylines in MLB or UFC where odds vary and true payouts are offered.
You have a strong edge on multiple games and want to maximize return on a small stake.
❌ When they don’t:
You’re parlaying standard -110 bets in football or basketball.
You’re chasing longshot wins with minimal edge or strategy.
🔚 The Verdict:
Risky, Fun, but Rarely Profitable Long-Term
Parlays can be fun, exciting, and yes — sometimes lucrative — especially when odds are fair.
But as a long-term strategy, they’re rarely profitable unless you’re sharp, selective, and exploiting true value in variable moneylines or niche markets.
For most bettors, they should be used sparingly, more for entertainment than consistent income.
