Cantor Fitzgerald Starts Institutional Block Trading in Kalshi Event Contracts

Cantor Fitzgerald said on Aug. 19 that it has started arranging institutional block trades in event contracts through Kalshi, becoming one of the first full-service investment banks to broker prediction-market transactions at institutional size on a CFTC-regulated exchange. The setup is aimed at solving a basic market-structure problem: prediction markets grew on retail activity, and thin order books can make it difficult for large investors to build multimillion-dollar positions without moving the market against themselves. Under the arrangement, Cantor will serve as an introducing broker and route execution through Kalshi’s block trading framework, while Susquehanna Predictions, part of Susquehanna International Group, will provide pricing and liquidity. Cantor said the business will sit inside its Global Markets division under co-CEOs Pascal Bandelier and Christian Wall, using a model the firm has already applied in equities and fixed income. The launch comes as Wall Street firms expand infrastructure around prediction markets, with Galaxy Digital opening an OTC desk and Crypto.com hiring a Wall Street veteran to grow its own institutional business in the sector.
