Interactive Brokers is launching a platform where users can place yes-or-no bets through Kalshi, CME Group and its own ForecastEx, a boost to prediction markets’ efforts to woo institutional investors. The online brokerage’s users, which include both individuals and institutions, will be able to access the platform to trade contracts related to elections, climate and the economy. Interactive Brokers currently doesn’t plan to list contracts it deems unrelated to those topics, such as those tied to sports and pop culture, according to the company.
