What is a Parlay?

A parlay is the American term for an accumulator. It combines multiple selections into one bet where all legs must win for a payout. Parlays are the most popular multi-bet type in US sports betting.

How Parlay Odds Work

With American odds, the parlay payout is calculated by converting each leg to decimal odds, multiplying them together, then converting back. Most sportsbooks calculate this automatically.

Example: 3-Team Parlay

3-team parlay at -110 each:

  • Each leg converts to 1.909 decimal
  • Combined: 1.909³ = 6.964
  • $100 stake returns $696.40 (profit $596.40)

Parlay vs Individual Bets

A $300 split across 3 individual $100 bets at -110 would return $191 each when winning. If all 3 win, total return = $573 (profit $273). The parlay returns $696 for just $100 staked — but if any leg loses, you get nothing.

Same Game Parlays

Same Game Parlays (SGPs) combine multiple selections from the same event. Because the outcomes are correlated (e.g., a team winning AND the total being over), the odds are adjusted differently than standard parlays. SGPs have become extremely popular with US sportsbooks.

Parlay Cards

Some retail sportsbooks offer fixed-odds parlay cards with pre-set payouts based on the number of legs. These typically offer slightly worse odds than true parlays but are easy to understand.
