The One Play
Guide
How combos work
A combo is a few player props tied together. We post a couple a day when the card has them. The legs come from different games, and the same player does not show up twice.
Every leg has to hit. One miss and the combo loses. That is the whole rule. We still grade each leg on its own, so you can see which one carried it and which one broke it.
What you see before the game
On the public page, a live combo shows the sports and the games. Members see the players. Once the games are final, the names and the stat lines go on the record for everyone.
Lottos: the long shots
A lotto is a big combo: 12 legs on the 12-Leg Lotto, fewer on the others. Every leg has to hit, so it hits rarely. The card shows Kalshi’s combo price in cents when it posted.
Lottos are built by our combo builder exactly as it builds them. They are shown in full to everyone, and the same leg can show up on more than one lotto.
Buy YES means you win that leg if the thing happens. Buy NO means you win it if it does not. On a NO leg, check that the Kalshi ticket says NO before you buy.

Check your local law. We post the card. We do not place the combo for you.
