The first US federally regulated exchange where you can trade on the outcome of any event.
Kalshi’s historical regulatory approval from the CFTC enables it to offer a new asset class called “event contracts,” which allow traders to take positions on whether a future event will happen or not. Kalshi aims to enable investors to trade on almost anything with economic relevance from Covid numbers to whether a bill will pass in Congress, broadening the historical definition of what a commodity derivative is and paving the way for the futures market to catch up to the novel risks facing the economy today.
Kalshi is backed by Sequoia, Henry Kravis, Charles Schwab, and Y Combinator.
