Cantor Fitzgerald Launches Institutional Block Trading on Kalshi

This matters less as a product launch than as a structural signal: prediction markets are being wrapped in the same intermediation layer that governs block equities, with a broker introducing privately negotiated trades and a dedicated market maker quoting them. That shifts Kalshi's addressable demand from retail flow toward institutions that need negotiated size and a counterparty relationship, and it gives Cantor and Susquehanna an early franchise in an asset class still defining its own plumbing. The open question is whether liquidity and pricing discipline hold up outside a single venue's ecosystem.
