Interactive Brokers ForecastEx: Event Contracts Review
ForecastEx is Interactive Brokers' exchange for event contracts, available to eligible IBKR clients. Contracts on economic data, climate and politics pay $1 if the outcome is right. It suits existing Interactive Brokers users; the range of markets is narrower than on dedicated platforms.
