Ninth Circuit tribal ruling leaves Kalshi's en banc bid exposed

Montana agreed to stand down. The joint stipulation runs to five pages, and its terms are precise: no enforcement, no cease-and-desist proceedings, no administrative action against Kalshi until the Ninth Circuit finishes whatever it intends to do with the petition for rehearing. Montana even accepted a thirty-day notice obligation before it can move again. On paper, that looks like Kalshi buying time. The problem is what Kalshi is buying time inside of.

The Ninth Circuit ruling the company is asking to be reheard already holds, as a matter of circuit law, that event contracts on tribal lands constitute illegal sports betting under the Indian Gaming Regulatory Act. The court's formulation — that Kalshi may reshuffle the cards but cannot change the hand — is not diplomatic language. It is a panel telling the full court there is nothing here worth reconsidering. En banc petitions succeed when a panel decision is in tension with prior circuit precedent or creates a circuit split that demands resolution. Kalshi's petition needs to argue one of those things. The ruling, as reported, suggests the panel believed it was applying settled law, not making new law.

The Montana pause is real relief, but it is geographically narrow. Missouri has not paused. Connecticut has not paused. Massachusetts federal court granted a preliminary injunction that runs against Kalshi on sports contracts, and that injunction is now approved. What Kalshi has in Montana is a thirty-day warning system, not a reversal of anything.

The broader enforcement picture has a structural feature that the individual platform lawsuits keep obscuring. Underdog's Connecticut complaint makes the preemption argument as cleanly as anyone has: the CFTC has sole authority over designated contract markets, and state gaming regulators have no jurisdiction to reach inside that federal envelope. Robinhood has filed the same argument. The federal courts in Connecticut will now have to decide whether the CFTC's silence on sports contracts — its deliberate non-prohibition — is itself a preemptive act, or merely an absence that leaves room for states to move.

That is not a question the Montana stipulation answers. It is not a question the Massachusetts injunction answers in Kalshi's favor. The CFTC has sat through tribal meetings, congressional hearings, and now a Ninth Circuit ruling without issuing a word of formal guidance. In a previous position, the sharpest analytical errors I observed were ones where an agency's silence was read as permission when it was actually preparation. The CFTC's silence here has lasted long enough that it no longer reads as permission to the courts that matter.

The consensus framing treats the Montana pause as a stabilisation. Kalshi has contained one front. The consensus is not wrong — but it is reading the map at the wrong scale. The Ninth Circuit en banc petition is the exposure that the state-by-state settlements do not touch, and the circuit law now on the books applies in every state the Ninth Circuit covers, regardless of what any individual attorney general agrees to hold off on.
