Cantor Fitzgerald brings institutional money into prediction markets

Susquehanna will price the block trades as Cantor brings institutional money into prediction markets

In April, a Houston-based environmental hedge fund took a position on the outcome of a California carbon-allowance auction. Greenlight Commodities brokered it. Jump Trading provided the liquidity. Kalshi cleared it. The trade was notable enough that Kalshi cited it in investor conversations for months afterward — a proof of concept that institutional hedging via event contracts could work at scale. On August 19, Cantor Fitzgerald made that proof of concept a product line.

Cantor announced it will act as an introducing broker for block trades in Kalshi's event contracts, with Susquehanna Predictions providing liquidity and pricing. The roughly three thousand institutional clients in Cantor's Global Markets division — hedge funds, family offices — can now access contracts covering weather outcomes, commodity prices, and corporate results including iPhone sales thresholds. The trades execute away from Kalshi's central order book, which matters: block trading infrastructure signals that someone expects ticket sizes too large for the standard exchange interface to absorb cleanly.

Co-CEOs Pascal Bandelier and Christian Wall framed this as applying eighty years of equities and fixed income access to a new asset class. That framing is partly marketing, but it contains a real observation. Cantor is not a fintech. It is a full-service investment bank, and its involvement changes the institutional legitimacy signal in a way that earlier partnerships did not carry at the same weight.

The mechanism Susquehanna's Joe Grubb described is the part that should interest anyone thinking about where prediction market volume goes from here. A fund concerned about Apple's earnings doesn't have to infer the outcome from equity price movement — it can take a position directly on whether iPhone sales exceed a stated threshold. That is a genuinely different instrument from anything available in listed options. It isolates the event rather than the price reaction to the event, and for certain hedging problems that is a more precise tool.

Clear Street has a similar arrangement with Kalshi. Marex has partnerships with both Kalshi and Polymarket. Talos connected market makers to Kalshi through existing trading infrastructure. The pattern across all of these is the same: Wall Street is building access infrastructure before it has clarity on where the regulatory lines settle. That is either a calculated bet that federal preemption holds and state-level enforcement becomes manageable noise, or it is a bet that institutional involvement itself creates political pressure against aggressive state action.

I think it is both, and I think Cantor's entry accelerates that dynamic in a way the earlier partnerships did not. Susquehanna is not a passive liquidity provider — it is one of the most sophisticated options market makers operating in US markets, and its dedicated prediction markets arm choosing to price these contracts is a statement about where it sees edge. When Susquehanna decides a market is worth making, the information content of that decision is not trivial.

What Cantor has not said is whether it plans to extend block trading to venues beyond Kalshi, or when the custom contracts institutional clients have reportedly discussed with the firm would launch. Those are the two variables that determine whether this is a distribution deal or the beginning of a structured products pipeline. The Houston carbon trade suggests the latter is already in motion.
