Kalshi

Kalshi runs an exchange where people trade event contracts, buying Yes or No positions on whether a specific future event will happen. It describes itself as the first exchange regulated by the US Commodity Futures Trading Commission dedicated to trading on outcomes, with markets on economics such as inflation, interest rates and unemployment, as well as politics and elections, climate, culture, sports, crypto, commodities, financial markets and technology. Kalshi has added perpetual futures, offers an API for developers and professional traders, and presents event contracts as a way both to express views and to hedge real-world risks.
