How MLB Parlay Odds Work

When you place a MLB parlay (or any type of parlay, for that matter), you are combining multiple MLB bets into a single wager. In order for the parlay to win, all individual bets (called “legs”) of the parlay must hit.

In exchange for the increased difficulty, you receive a much higher payout than you would if you just bet each individually.

The following table shows the standard payouts on parlays in which each leg has -110 odds as well as the true probability and fair odds if there were no “juice” or “vig” charged by the sportsbook:

# Parlay Legs

Implied Probability


True Probability

Fair Odds

2 team parlay





3 team parlay





4 team parlay





5 team parlay





6 team parlay





7 team parlay





8 team parlay





9 team parlay





10 team parlay





Note that the odds on MLB same game parlays differ based on how related the included selections are to each other. 

For example, you would receive a lower payout on a same game parlay that includes Aaron Judge to hit 2+ HRs and the Over to hit since the game is more likely to go over the run total if he does hit 2+ HRs.
