Build a Kalshi parlay (a combo, or prop stack) from live markets, or paste one you already have, and get a real read on it: the combined odds, the payout multiple after fees, your weakest leg, any legs that barely add to the payout, correlation warnings, and a verdict on whether to swap something out. Works while you assemble and after.
Free grades the bet. Pro shows you how to win money on it. The exact hedge that locks a guaranteed profit, the plan to beat the combo, and your real risk. Try it free for 7 days, no card.

Does Kalshi have parlays?
Not as a one-click ticket. You replicate a parlay by rolling the proceeds of one winning contract into the next leg, paying a trading fee at each step. This builder models that exactly, including the fees.
How is the parlay payout calculated?
Your stake buys contracts at the first leg's price; if it wins, every contract pays $1 and the proceeds (minus the taker fee) roll into the next leg. The combined probability is the product of the legs' implied probabilities, assuming independence.
Why is my multiple lower than the fair odds?
Fees. Each leg charges a taker fee that scales with contracts and price, so a fair 8x three-legger typically pays closer to 7.5x once fees compound. The builder shows both numbers so the cost is visible.
Can I paste my combo or prop stack to evaluate it?
Yes. Hit “Paste a ticket,” drop in your legs one per line (from a Kalshi slip or a plain list like “Chiefs to win YES 62c”), and it matches each to a live market and analyzes the whole thing: odds, weakest leg, dead weight, and a verdict.
Which leg should I swap out of my parlay?
The evaluator flags your weakest link (the leg least likely to hit, since one miss ends the ticket) and any dead-weight legs, ones priced so high they barely raise the payout while still adding a way to lose. Dropping dead weight raises your odds with little cost to the winnings.
Are Kalshi parlays, combos, and prop stacks the same thing?
People use the words interchangeably. A parlay (or combo, or prop stack) is any bet that needs several outcomes to all hit. On Kalshi you build one by rolling winnings from one contract into the next, and this tool evaluates it either way.
I've hit most of my legs, should I hedge?
Once some legs have won, mark them as won and the tool shows hedge options: bet against your riskiest remaining leg to lock in a guaranteed floor. A full hedge locks the same profit no matter what; a partial hedge keeps more upside if your parlay still hits. It shows the exact stake and the locked amount at 25/50/75/100%.
Can I evaluate a big combo?
Yes, up to 16 legs, matching what Kalshi allows. The odds ladder shows how many you're likely to land versus the long odds of a clean sweep.
Prefer plain math on hypothetical prices? The simple parlay calculator does that. Not financial advice.
