Interactive Brokers Unifies Prediction Market Access Across Kalshi, CME, and ForecastEx
Interactive Brokers (IBKR) expanded its prediction market offering on May 14, giving clients unified access to contracts across Kalshi, CME Group, and ForecastEx from a single account. The company said in a BusinessWire release that clients can search and trade across all three venues with no requirement to open or fund separate accounts at each exchange.
The expansion covers contracts on economic indicators, political events, and financial benchmarks.
What the Platform Now Offers
The unified interface lets IBKR clients discover and execute prediction market contracts across Kalshi, CME, and ForecastEx through a single search function. Clients do not need to separately fund accounts at each venue, reducing the operational friction that has historically kept retail participants from spreading exposure across multiple prediction exchanges.
IBKR did not disclose the number of contracts available at launch or whether margin offsets will apply across positions held at different venues through the platform.

Background
Prediction markets, platforms where participants buy and sell contracts tied to the probability of real-world outcomes, have expanded rapidly in the United States after regulatory clarity improved in 2024. Kalshi received CFTC authorization to list event contracts in 2023 after a prolonged legal dispute.
ForecastEx, CME’s own prediction market venue, launched in 2023 as the exchange sought to capture institutional event-contract flow. Interactive Brokers entered prediction markets in stages, initially offering Kalshi contracts alone before broadening its coverage.
The May 14 expansion is the first time the firm has offered simultaneous access to all three major U.S.-regulated venues from one interface. Combined daily volume across the three venues has grown sharply since 2024, driven by interest in election contracts and macroeconomic outcome markets.

What to Watch
The key metric for this expansion is whether IBKR’s large retail and institutional client base materially raises trading volume on Kalshi and ForecastEx, two venues that have operated with thinner liquidity than CME’s event contracts.
If unified access drives volume concentration, smaller venues may face pressure to negotiate tighter integrations with other prime brokers. IBKR did not announce fee structures for cross-venue trading.
