Nine companies received a cease-and-desist order from Connecticut's Department of Consumer Protection in the same week. Eight of them went quiet. Underdog filed thirty-nine pages in federal court.
That asymmetry is worth sitting with. When a regulated platform files for declaratory judgment and a permanent injunction in the same motion, it is not running a legal defense. It is choosing a venue for a larger argument.
The argument Underdog is making is not novel — Robinhood and the CFTC itself have pressed versions of it in Connecticut already. Designated contract markets, they say, operate under federal law, and states have no authority to reach them. Connecticut's position is that age restrictions, self-exclusion lists, and prohibitions on wagering on in-state college teams represent exactly the kind of consumer protection that state law was designed to enforce. Both positions have genuine legal weight, which is why this is going to a court rather than a press release.
What Underdog's complaint does, though, that the others have not done as cleanly, is make the CFTC the centerpiece. The thirty-nine pages ask the federal court to confirm that the Commission has sole jurisdiction over event contracts on DCMs — including sole authority to determine whether any category of contract is contrary to public interest. That framing puts Connecticut's enforcement not just in tension with federal preemption but in conflict with an active regulatory body. The court cannot rule for Underdog without implicitly ruling on where CFTC authority begins and ends.
This is where I think the consensus read is slightly off. The coverage has treated the Connecticut standoff as a collection of parallel platform disputes. I read it as a single proceeding that is now being deliberately shaped. With Robinhood, Underdog, and the CFTC all pressing preemption in the same district, the U.S. District Court for the District of Connecticut is being asked to produce something close to a definitive federal statement on the jurisdictional question. That is not the usual texture of a cease-and-desist fight.
I am adjusting for my own tendency to find the downside scenario. The upside read here — that a favorable district court ruling establishes clean federal preemption and clears the state enforcement wave — is more probable than I would naturally weight it. The mechanics favor it: the CFTC's designation of these platforms as DCMs is not disputed, and federal preemption doctrine does not require the agency to be particularly active, only to have occupied the field.
The risk I keep returning to is not legal. It is sequencing. Montana's pause is contingent on the Ninth Circuit's en banc review of a decision that already went against Kalshi. If that court affirms, states gain precedent with teeth. A Connecticut district court ruling the other way would create a circuit split of a different kind — not on tribal law, but on the basic preemption question — and that split could persist for years before resolution.
The prediction markets tracking federal preemption outcomes in the Connecticut proceedings are pricing this as more settled than the underlying procedural picture warrants. My view is that the range of outcomes is wider than current pricing reflects, and the tail that matters is not Underdog losing — it is Underdog winning on narrow grounds that leave the tribal IGRA question untouched, producing a patchwork that nobody actually wanted.

Federal preemption doctrine holds that if the CFTC has occupied a regulatory field through designating platforms as designated contract markets under federal law, states cannot enforce conflicting rules in that same field. Connecticut argues that age restrictions, self-exclusion lists, and prohibitions on wagering on in-state college teams represent consumer protection that state law was designed to enforce. The doctrine does not require the CFTC to be particularly active, only to have designated the field—but courts must still determine whether Connecticut's specific enforcement measures conflict with federal jurisdiction over event contracts on DCMs.
Connecticut's Department of Consumer Protection issued cease-and-desist orders to nine companies, including Underdog, requiring age restrictions, maintenance of self-exclusion lists, and prohibitions on wagering on in-state college teams. Underdog's federal lawsuit challenges whether Connecticut has authority to impose these particular requirements on designated contract markets operating under federal regulation, rather than defending against the order itself.
A favorable district court ruling for Underdog would establish that the CFTC has sole jurisdiction over event contracts on DCMs, including sole authority to determine whether any contract category is contrary to public interest. This would create clean federal preemption and potentially clear the wave of state enforcement actions, though the outcome depends on whether other federal circuits reach the same conclusion or create a split in how preemption applies to platform-offered contracts.
The sequencing of decisions creates pricing uncertainty across platforms like Polymarket and other event contract exchanges. Montana's pause on enforcement is contingent on the Ninth Circuit's en banc review of a prior decision against Kalshi—if that court affirms, states gain precedent with enforcement teeth, which would contradict a Connecticut district court ruling in Underdog's favor and create competing circuit authority over whether state consumer protections can bind designated contract market operators.
