Ninth Circuit dealt states their first real win against Kalshi

Neal Kumar issued his statement from what he called a tiny NYC apartment — the founding origin, the local-roots framing, the open-door invitation to the Attorney General. It is a well-constructed piece of public positioning, and it will not resolve anything.

New York now has active suits against four prediction market operators. The pattern that has emerged is not a wave of coordinated enforcement so much as a collision of two legal theories that cannot both be right, being tested in every circuit simultaneously. The Third Circuit sided with federal preemption. The Ninth Circuit went the other way. The Supreme Court has not yet said whether it will hear the question. Until it does, every operator in this space is running a business whose legal status depends on which courthouse its state's attorney general chooses.

That asymmetry is the thing worth pricing carefully. Kalshi and Polymarket are both federally regulated under the CFTC, both arguing the same preemption theory, both now facing state-level suits in jurisdictions where the circuit precedent is either hostile or unresolved. The NCLGS amicus brief adds a political dimension that the pure legal argument cannot contain: if prediction markets achieve full federal preemption, the brief argues, traditional sportsbooks face an incentive to restructure themselves in the same mold. The tax revenue argument follows from that. State gaming regulators are not fighting this battle only for doctrinal reasons.

I want to be precise about where I think the consensus is wrong. The dominant read right now treats this as a binary — either the CFTC wins at the Supreme Court and the industry is settled, or the states win and prediction markets retreat from sports contracts. I don't think it lands there. What I have seen in analogous federal-state jurisdictional fights is that the Court tends to find the narrower path: preemption for some contracts, state authority for others, with the line drawn at something the CFTC will spend three years trying to define. That outcome leaves every operator in a longer period of uncertainty than the binary suggests, and it prices the near-term operational risk too cheaply.

The age floor question New York has layered into the Polymarket suit is worth separate attention. Most prediction markets require users to be eighteen. Sports betting minimums in many states sit at twenty-one. That three-year gap is not a rounding error in a state lawsuit — it is a separate cause of action that survives even if the preemption argument goes against New York entirely. Polymarket can win on federal grounds and still face an injunction on the age question. I have not seen that scenario adequately weighted anywhere.

I am adjusting for my own bias here: I find tail risk in regulatory fights more readily than the upside warrants. The upside — a clean Supreme Court ruling that settles federal preemption broadly — is genuinely available and probably more likely than not. But the downside scenario, a narrow ruling that resolves nothing and extends this fight another two to three years while states continue to file, is the kind of outcome that compounds operational drag in ways that a single probability estimate doesn't capture.
