Cantor Fitzgerald to broker Kalshi block trades for 3,000 institutional clients
Cantor Fitzgerald will broker block trades on Kalshi for about 3,000 institutional clients. SIG will provide pricing. The trades will clear through the CFTC. The arrangement expands on Cantor's earlier prediction market offerings and gives Kalshi a dedicated channel to Wall Street firms that previously lacked direct access to event contracts. The move deepens Cantor's bet that regulated prediction markets will become a standard institutional asset class.
Kalshi now faces a crowded institutional gatekeeper landscape where Cantor Fitzgerald and Trading Technologies pitch the same hedge funds multiple prediction market pipes. Cantor's 3,000-client desk gives Susquehanna a dedicated market-making channel competing directly for order flow against TT's dual-venue Kalshi and OG.com connection.
Institutional clients will not maintain redundant integrations, so the venue that shows stronger volume through Cantor's Q4 2026 launch window will capture the larger share of a limited client pool. For Kalshi, winning this desk means proving contract breadth and execution quality against a platform backed by Crypto.com's capital. A lopsided flow split would signal which exchange has won the institutional narrative and which faces the costlier path of direct retail acquisition.
