Kalshi is a regulated prediction market platform where users trade contracts based on the outcomes of real-world events. Instead of placing traditional bets like you would at a sportsbook, Kalshi allows users to buy and sell “Yes” or “No” contracts tied to specific questions. These questions can cover a wide range of topics, including: Each contract is priced between $0 and $1, which represents the market’s estimated probability of that event occurring. For example, if a contract is priced at $0.65, the market is implying a 65% chance that the event will happen. If the prediction is correct, the contract settles at $1. If the outcome is incorrect, it settles at $0. Unlike traditional sportsbooks, where bettors wager against the house, Kalshi functions more like a financial exchange where users trade against other participants in the market. The platform operates under oversight from the Commodity Futures Trading Commission (CFTC), making it one of the only federally regulated prediction markets available to U.S. users.
