Question 1

Can you parlay on Kalshi?

Accepted Answer

Yes. Kalshi has a native multi-leg product called Combos, launched in September 2025, which pays $1 per contract only if every leg you picked resolves in your favor and $0 otherwise. A Combo is priced by request for quote rather than from a standing order book, so market makers quote your specific combination and a fill is not guaranteed. The default on Kalshi is still the single market: each contract on this page has its own book, its own price, and its own settlement. Buying several single markets together is not a parlay — the legs settle independently, so being right about two of three still pays.

Question 2

Which NFL markets does Kalshi list?

Accepted Answer

This screener reads three Kalshi NFL series directly from the exchange's public API: KXNFLGAME (game winner), KXNFLSPREAD (winning margin bands), and KXNFLTOTAL (total points scored). Each row is one binary market with its own order book, YES and NO mid prices in cents, 24-hour contract volume, and open interest.

Question 3

Does Bot for Kalshi build parlays or Combos?

Accepted Answer

No. Every bot places single-market limit orders on one market at a time. There is no linked multi-leg order type and no request-for-quote integration, so the product cannot assemble, price, or submit a Combo. What it can do is run several independent bots at once, each on its own market with its own trigger, limit price, stop, and position cap.

Question 4

What do the volume and open interest columns mean?

Accepted Answer

24-hour volume is how many contracts actually changed hands today — the honest measure of where the action is. Open interest is how many contracts are still outstanding, which is closer to how much money is committed to the game overall. Neither is a prediction; a heavily traded market is usually the most efficiently priced one.
