Cantor joins Kalshi as New York pursues 36 billion dollar claim

Pascal Bandelier signed the paperwork on a Wednesday. As co-CEO and global head of equities at Cantor Fitzgerald, he committed one of Wall Street's oldest institutional brokerages — eighty-plus years of Treasury desks and fixed-income relationships — to serving as introducing broker for event contract block trades on Kalshi, a platform that New York State is simultaneously pursuing for thirty-six billion dollars in damages and attempting to shut down entirely.

That is not a contradiction Cantor is hiding. It is the bet.

The arrangement is specific: Cantor arranges and facilitates institutional-size block trades in event contracts, executed at a single negotiated price away from Kalshi's central order book, with Susquehanna Predictions providing liquidity on the other side. Susquehanna, which describes itself as the first quantitative trading firm to build a dedicated prediction markets business, is already one of the most active market makers in event contracts. Cantor brings the client relationships. The infrastructure already exists. What has been missing, in Bandelier's telling, is an institutional intermediary that the buy side recognizes.

The timing is not incidental. Kalshi is operating under a CFTC emergency order that allowed it to remain in New York despite the state's lawsuit — the same lawsuit the New York City Council compounded last week by opening an investigation into deceptive marketing practices targeting minors across four platforms, Kalshi among them. Cantor launched its block trading desk into that environment, on that same Wednesday.

The market that consensus has priced as a preemption winner is not the market I would take at face value. The CFTC's emergency authority kept Kalshi operational in New York, but a federal court in Connecticut has already held that such orders carry no binding reach over state courts. The preemption theory that Novig is litigating across five states — New York, Massachusetts, Washington, New Mexico, and Wisconsin — lost its first preliminary injunction test in Wisconsin on July 28, where a federal judge found the agency had not demonstrated a likelihood of success on the preemption claim. That ruling did not resolve the underlying question, but it is the most recent federal assessment of how strong that argument actually is. Novig's New York hearing is scheduled for September 11. Whatever that court says will be the next real data point, and it will arrive in a legal environment where the CFTC's own June rulemaking proposal would prohibit contract categories — player injuries, officiating decisions, discrete in-game actions — that form the core of sports prediction market volume.

Cantor's entry will be read as validation. Institutional infrastructure arriving at scale does function as a signal that sophisticated capital has assessed the regulatory risk and priced it as survivable. That reading is not wrong. It is also incomplete.

The legal standard that controls the New York litigation is federal preemption under the Supremacy Clause, as applied to CFTC-designated contract markets under the Commodity Exchange Act. The question is whether DCM status under 7 U.S.C. § 7a-3 displaces state gambling law enforcement — not whether it should, and not whether the CFTC believes it does, but whether a federal court will hold that Congress expressed a clear intent to occupy that field completely when it enacted Dodd-Frank's event contract provisions.
