Kalshi is an online betting platform where people can bet on anything with anyone. It can be on things from "Will Trump get impeached by the end of the month" to "Who will win the Oscars?" Kalshi believes people should be able to capitalize on what they know and are passionate about.

Kalshi expands what people can bet on and allowing them to bet against each other, on their own terms. Users don't pay anything to play, but the biggest winners get cash prizes. Kalshi aims to become a betting network where people can post any question they can think of and bet on it. Their first betting model is a pari-mutuel betting platform, in which users who bet on the right outcome win money from those who bet on the wrong one, divided proportionally among the winners. Currently, questions come from the sports, politics, financial, and entertainment sectors. On Kalshi, prizes increase as more users join.
