Cantor opens Kalshi prediction markets to institutions

Cantor Fitzgerald announced on August 19, 2026 that it will offer its roughly 3,000 institutional clients access to Kalshi's prediction markets, making it one of the first full-service investment banks to provide institutional block trading in event contracts on a CFTC-regulated exchange. Cantor will act as an introducing broker, arranging large block trades outside the central order book, while Susquehanna International Group will serve as market maker providing pricing and liquidity. The move addresses the gap between retail-driven growth in prediction markets and institutional participation, which has lagged due to lack of scale on regulated venues. Institutional clients, including hedge funds and family offices, are showing interest in contracts tied to weather, commodities, corporate earnings, iPhone shipments, and AI infrastructure. Cantor can also request custom markets from Kalshi, subject to CFTC approval. This partnership intensifies competition with offshore rival Polymarket and strengthens Kalshi's institutional distribution, following its first block trade in April and an alliance with IO Interactive.
