Interactive Brokers expanded its prediction markets offering by launching a unified trading service that integrates contracts from Kalshi, CME Group, and ForecastEx into a single platform. Eligible clients can trade these event-based contracts alongside stocks, options, forex, futures, crypto, and bonds. The new service builds on the broker’s earlier Kalshi integration and broadens access to prediction markets within the same trading environment, with Kalshi and CME-related contracts scheduled to be introduced in phases.
