Seems like the high growth of Kalshi has sparked some action—Interactive Brokers' (IBKR) prediction market, ForecastEx, has also started picking up trading volume in recent months. IBKR ForecastEx reached $1.99 billion in trading volume last December, and this month’s volume has already surpassed $1 billion. However, there’s still quite a way to go before the 2024 election month. Similarly, during the 2024 election month, the open interest peaked at over $3 billion, even surpassing Polymarket and Kalshi at one point. But currently, it’s only around $4 million. Since August 2024, IBKR ForecastEx has generated over $10 million in fees, with a fee rate of approximately 1%. That means it’s brought in about $3 million in the past two months alone. As a CFTC-regulated DCM market, unlike Kalshi, which focuses on sports and retail users, IBKR ForecastEx has almost no sports event predictions. It seems like they’re intentionally avoiding regulatory issues, leaning more towards economic, political, and institutional predictions. Shoutout to the GOAT @datadashboards
