About the Company

Kalshi

Regulated event-contract trading platform

Kalshi runs a US federally regulated exchange that lets traders speculate on whether future events will occur using event contracts. These contracts are approved by the CFTC and enable positions on outcomes like statistics or legislative results. Traders place bets on events via Kalshi’s trading platform, and the company earns revenue from transaction fees on each trade. Kalshi differentiates itself by being the first federally regulated market for event contracts, focusing on a new asset class within the futures ecosystem, and attracting both individual investors and institutional traders. Its goal is to give participants a regulated venue to hedge or speculate on economically significant events, expanding the scope of traditional futures markets.
