Cantor Fitzgerald said it has begun institutional block trading in prediction markets on Kalshi, giving professional clients a way to negotiate event-contract trades away from the central order book. The firm said the business will run through its Global Markets division and start on Kalshi, with additional venues expected later.
Cantor described itself as an introducing broker, arranging and facilitating institutional-size block trades for clients on a CFTC-regulated exchange. The company said the trades would be negotiated at a single price through Kalshi’s block-trading framework, rather than in public view on the exchange’s main order book.
The move reaches into a market that has lagged in institutional participation. A Closing Line roundup said Cantor’s roughly 3,000 institutional clients will be able to negotiate block trades in yes-or-no event contracts tied to weather, commodities and corporate results.
Another report said block trades are large, privately negotiated transactions typically done outside public markets to limit volatility. It also said clients had shown interest in Kalshi’s climate, weather and economic indicator markets, which fit hedging strategies more familiar to institutional desks than the sports-related contracts that have powered much of Kalshi’s retail growth.
Cantor said it is one of the first full-service investment banks to offer institutional clients access to block trading in event contracts on a regulated exchange. Pascal Bandelier, the firm’s co-chief executive and global head of equities, said Cantor has spent more than 80 years building institutional access to new markets and sees prediction markets as the next one.
The company said it is applying the institutional trading model it developed across equities and fixed income to prediction markets, and that the business will sit within its Global Markets division under Bandelier and Christian Wall. Max Crowley of Kalshi said Cantor brings deep institutional relationships and significant experience in equities and fixed income, while Kalshi is looking for partners who can think creatively about how event contracts fit into client portfolios.
Cantor also said Susquehanna Predictions will provide pricing and liquidity for the market. A separate report described Susquehanna International Group as the market maker, while Cantor’s announcement used the Predictions name.
TechEchelon said Cantor first approached Kalshi several months before the announcement, and that Cantor can request new markets tailored to client demand, subject to CFTC approval and enough liquidity. The report also said the launch was part of a series of moves Kalshi made in 2026 to attract professional capital, after what it described as the first block trade on an event contract exchange in April.
