PARLAYS & COMBOS · CHECKED 6 OCT 2026
Why a parlay costs more
Yes. Kalshi calls them combos: each combination is its own market with its own order book, priced by request for quote, and its maker fee is half the taker fee where a single market charges a quarter.

THE RULES, SOURCED
Combos are priced through a request for quote, a fill is not guaranteed, and a filled combo cannot be cancelled help.kalshi.com ↗. The maker fee multiplier is 0.5 against the standard 0.25 docs.kalshi.com ↗, except combos made only of independent NFL legs created after 19 August 2026, which carry no maker fee docs.kalshi.com ↗.
