Interactive Brokers, the veteran electronic brokerage founded by Thomas Peterffy in 1978, offers event contracts through its ForecastEx exchange and ForecastTrader interface, sitting alongside stocks, options, and futures. It is aimed squarely at serious, multi-asset traders who want event contracts inside a professional-grade platform.

Regulatory standing and execution quality are strong, but the catalog is more limited than dedicated prediction venues and the platform's complexity is overkill for casual users. Reporting in 2026 noted a pullback in some ForecastEx activity amid broader consolidation.
