Kalshi is a CFTC-regulated prediction market exchange where users trade on the outcome of real-world events — from elections to economic data to weather. HQ: San Francisco.
About
Kalshi is the first U.S. federally regulated event contracts exchange, authorized by the Commodity Futures Trading Commission (CFTC) to operate a marketplace where participants can trade financial contracts based on the outcomes of real-world events. Founded in 2018 by Tarek Mansour and Luana Lopes Lara, Kalshi went through a years-long legal battle with regulators to establish the legitimacy of event contracts as a regulated financial product in the United States. Its CFTC approval in 2020 created a new class of financial instrument for Americans who previously had no legal domestic venue for prediction markets.
