Cantor Fitzgerald opens Kalshi event contracts to about 3,000 institutional clients
Cantor Fitzgerald launched institutional block trading in Kalshi event contracts on Wednesday, acting as an Introducing Broker for roughly 3,000 of its institutional clients. The arrangement gives Kalshi access to Cantor's institutional distribution network and marks a significant channel expansion for the regulated prediction market platform. Cantor is among the first major investment firms to provide clients with institutional trading on prediction market event contracts.
Kalshi now has a direct pipeline to roughly 3,000 institutional clients through a top-tier broker-dealer that previously handled only traditional asset classes. Hedge funds can place large block trades without the size limits that constrain retail platforms. That changes who controls the order flow: external market-making desks set pricing and liquidity terms, not Kalshi's internal systems.
For rivals like Polymarket and OG.com, the partnership raises the competitive floor. Broker-dealer access is becoming table stakes for institutional volume. Any platform without similar infrastructure must now court introducing brokers or watch professional desks trade elsewhere. The move also tests whether event contracts can absorb institutional position sizes without price swings that would scare conservative asset managers away.
Kalshi now has two live institutional distribution pipelines from the same broker-dealer: Cantor's introducing-broker channel for block trading, and the earlier Susquehanna-priced hedge-fund access.
