Cantor Fitzgerald launches institutional block trading for event contracts
Cantor Fitzgerald & Co launched institutional block trading in event contracts on August 19, 2026. The new service lets large traders negotiate private block trades in prediction market products without moving public order books. The firm said institutional clients will initially be able to execute block trades in these products. Cantor is positioning the offering as a Wall Street-scale execution venue for event contracts.
Cantor is assembling a full institutional pipeline for event contracts that rivals cannot yet match. The block desk complements its introducing-broker deal for Kalshi, giving hedge funds both execution and clearing through one familiar counterparty. That reduces the operational friction that has kept asset managers out of prediction markets.
Competitors like Polymarket and FanDuel Predicts still lack comparable broker-dealer distribution, though Trading Technologies is building rival connectivity. The question is whether Cantor can convert its brand recognition into committed volume, or whether institutional clients will treat event contracts as a curiosity. If block flow materializes, it validates event contracts as a portfolio tool and pressures rivals to secure similar infrastructure partnerships at premium terms.
