Like other prediction markets, Kalshi lets users make trades based on a variety of different subjects and events. For example, you could participate in a market focused on the results of a basketball game, or something more unusual, like who'll win the current season of Survivor. Despite resembling gambling, online predictive markets aren't currently regulated by state gambling laws, and instead classify bets as a type of futures contract, placing them under the purview of the CFTC. That hasn't stopped states from trying to regulate prediction markets anyway. For example, Nevada sued Kalshi for operating a sports gambling market without a permit earlier in February.
