IBKR Aggregates Kalshi and CME for Professional Traders
The Interactive Brokers (Nasdaq: IBKR) update introduces a single interface designed to consolidate these three liquidity pools. Eligible clients can now trade macro outcomes alongside traditional assets like stocks, crypto, and forex through a single account structure.
The platform utilizes an order routing system that scans for the best net price across the three connected venues. This system is intended to account for exchange fees and liquidity in real-time, allowing for automated execution.
Contract categories on the platform focus on election outcomes, climate events, and economic indicators such as GDP and inflation. Sports and pop culture contracts are currently excluded from the offering.
The launch occurs amid a period of rising volume in the event-contract sector. Data from Kalshi indicates the exchange handled $23.8 billion in trading volume during 2025, which represents a 1,108% increase year over year.
Interactive Brokers CEO Milan Galik noted that these markets are being used by investors to address risk and uncertainty. He stated that the new tool utilizes the firm’s existing infrastructure to provide access to these venues.
“ Prediction markets are reshaping how investors think about risk and uncertainty,” Galik stated. “IBKR’s Prediction Markets combines the execution advantages of competing platforms with the trusted infrastructure our clients already rely on.”
The functionality is integrated into the brokerage’s existing environment, with positions appearing in the standard portfolio view. This setup provides consolidated reporting and tracking for event contracts next to other holdings.
For positions held on ForecastEx, the firm is offering an incentive coupon that currently yields approximately 3.14% APY. This feature is part of the broader rollout of the affiliate exchange’s products.
Tarek Mansour, CEO of Kalshi, described the integration as a significant development for the growth of prediction markets. He suggested the partnership reflects an increase in interest from sophisticated investors and financial institutions.
CME Group Chairman Terry Duffy also commented on the launch, citing growing retail demand for trading views on economic benchmarks. CME event contracts are being added to the IBKR interface on a rolling basis.
Product availability and eligibility remain subject to regional regulations and age requirements. For example, U.S. election contracts are limited to eligible U.S. residents.
With this rollout, Interactive Brokers has created a centralized gateway for event-driven trading. By aggregating several industry exchanges, the firm provides a streamlined method for participants to engage with probability-based contracts.
