How Parlay Betting Works
A parlay combines two or more individual bets into a single wager. All legs must win for the parlay to pay out. The advantage is a much higher payout than placing each bet individually. The downside is that one loss kills the entire bet. A standard 2-leg parlay at -110 per leg pays +264, while a 4-leg parlay pays +878. The math works by multiplying the decimal odds of each leg together.
When Parlays Have Positive Expected Value
Most parlays are bad bets because the sportsbook compounds their edge on every leg. However, correlated parlays — where one outcome makes another more likely — can offer real value. For example, if an AI model identifies a team likely to dominate, parlaying their moneyline with the over could be +EV because both outcomes are linked. Our AI prediction models help identify these correlated opportunities across NFL, NHL, Tennis, and March Madness.

Parlay Calculator FAQ
How do parlay odds work?
Parlay odds multiply the decimal odds of each leg. A 2-leg parlay at -110 and -110 combines to +264. Every leg must win.
Are parlays worth it?
Standard parlays have a higher house edge than straight bets. Correlated parlays (linked outcomes) can offer value. Use AI predictions to find correlated opportunities.
How many legs can a parlay have?
Most sportsbooks allow 2-15 legs. More legs = higher payout but dramatically lower probability. Keep parlays to 2-4 legs for realistic win chances.
