Prime Brokers to Give Wall Street Institutions Access to Kalshi Prediction Markets
Kalshi is a U.S. Commodity Futures Trading Commission-regulated event-contract market where investors can trade on the probability of political, economic and other outcomes. The involvement of prime brokers including Clear Street and Marex Group means hedge funds can participate through established clearing and risk-management channels, signaling that prediction markets are evolving from a retail product into a tool for institutional asset allocation and hedging.
Bloomberg reported on March 11, 2026, that Clear Street, valued at more than $12 billion, expected to clear its first Kalshi trade by the end of March and expand the service later in the year. Marex Group, valued at about $2.6 billion, plans to follow within months. Marex said demand from large institutions was rising, while Kalshi CEO Tarek Mansour said billions of dollars were already flowing through the platform each week.

The history behind this eventInteractive Brokers Integrates Kalshi, Bringing Event Contracts to a Mainstream Brokerage
Prediction markets use event contracts to reflect the probability of political, economic and sporting outcomes, offering both price discovery and risk hedging. U.S.-regulated Kalshi raised $1 billion earlier in 2026 at a $22 billion valuation, signaling that such products are moving beyond crypto circles and into mainstream finance.
Interactive Brokers launched a unified interface on May 14, 2026, connecting three markets: Kalshi, CME Group and its own ForecastEx. Eligible customers can use their existing IBKR accounts to search, compare and trade event contracts without opening separate accounts or funding each platform individually, while managing the contracts alongside traditional investment portfolios.
Kalshi Facilitates First Large Institutional Prediction-Market Block Trade
Kalshi is an event-contract exchange regulated by the U.S. Commodity Futures Trading Commission, with contracts settling according to the outcomes of specified events. Greenlight Commodities has brought an NFA-registered framework for privately negotiated trades and centralized clearing to prediction markets. This allows institutions to hedge or invest with defined risk around individual events such as carbon prices, marking a significant step toward a more institutionalized market structure.
On April 27, 2026, Greenlight Commodities announced that it had brokered the first large institutional over-the-counter trade on Kalshi, with a Houston-based environmental hedge fund and Jump Trading Group on opposite sides. The trade was worth a six-figure dollar amount, but the exact value was not disclosed. The contract was linked to the settlement price of California’s 47th joint carbon allowance auction on May 20. Bernstein described the transaction on May 4 as a milestone in the market’s institutionalization.
Kalshi Wins Approval to Offer Margin Trading to Institutional Investors
Kalshi is an event-contract exchange regulated by the U.S. Commodity Futures Trading Commission (CFTC), with markets covering elections and economic data. Traditional prediction markets require positions to be fully collateralized, limiting capital efficiency. The company raised $1 billion at an $11 billion valuation on December 2, 2025, making expansion into the institutional market a key driver of growth.
A National Futures Association (NFA) filing dated March 24, 2026, shows that Kalshi affiliate Kinetic Markets LLC has been approved to register as a futures commission merchant (FCM). The license will allow the platform to initially offer margin trading to institutional investors, enabling them to establish positions with less upfront capital. Chief Executive Tarek Mansour said the product would launch soon but did not disclose a launch date or leverage ratio.
