Kalshi, a regulated prediction market platform, is experiencing a significant influx of institutional interest, with major financial firms seeking to integrate its event-based contracts into traditional workflows for risk management and probabilistic forecasting. This trend marks a shift from viewing prediction markets as purely speculative tools to treating them as structured financial instruments.
Prime brokers Clear Street and Marex Group are preparing to offer their institutional clients, including hedge funds, direct access to Kalshi's platform. These firms are evaluating internal use cases such as hedging and macro forecasting. To facilitate this institutional participation, Kalshi has expanded its infrastructure partnerships, notably collaborating with fintech firm FIS to introduce clearing and settlement capabilities designed for banks and asset managers.
The institutionalization push is further bolstered by a partnership with Tradeweb, a major market platform processing over $2.6 trillion in daily volume. Tradeweb has made a minority investment in Kalshi and is working to distribute its data and analytics, aiming to build an institutional-grade marketplace for event contracts.
ARK Invest has formally adopted Kalshi's prediction market data into its research process. The firm will use the data to track real-time expectations for macroeconomic releases, regulatory approvals, and technology progress, applying it to research, portfolio planning, and risk management. ARK's Cathie Wood stated, "Bringing prediction markets into institutional workflows is a natural next step for innovation in financial research."
The sector is witnessing explosive growth. Combined monthly volumes across leading platforms like Kalshi and Polymarket reached approximately $17.9 billion in February 2026. Kalshi alone processed roughly $23.8 billion in total notional volume in 2025, representing over 1,100% year-over-year growth, with peak daily volumes nearing $291 million in early 2026.
This growth occurs amidst increasing regulatory scrutiny in the United States. While Kalshi operates under CFTC oversight, policymakers debate the classification of event contracts. Recent legislative discussions have focused on restricting markets tied to political and sports outcomes. Kalshi has implemented safeguards against insider trading to strengthen market integrity and align with institutional standards.
The trend is gaining validation beyond finance. A recent Federal Reserve paper highlighted that Kalshi's macro markets provide a "high-frequency, continuously updated, distributionally rich benchmark" for researchers and policymakers, offering a real-time view of changing expectations that complements traditional surveys and models.
