Kalshi Loses Iowa Injunction: Gambling Law Not Preempted

A federal judge refused on September 8, 2026 to stop Iowa from enforcing its gambling laws against Kalshi, holding that the company's sports event contracts are not "swaps" under the Commodity Exchange Act and that Iowa's gambling statutes are therefore not preempted. The order closes no Iowa account and does not require Kalshi to stop trading in the state. What it takes away is protection: Kalshi's own filing had told the court it has "nearly 42,000 verified users in Iowa with millions of dollars invested" on its exchange, and the only thing the order records holding Attorney General Brenna Bird back was a promise not to open an investigation before the injunction motion was decided. It has now been decided.

The case is KalshiEX LLC v. Bird, No. 4:26-cv-00109, in the US District Court for the Southern District of Iowa, before District Judge Stephen H. Locher. We read the 23-page order off the federal docket rather than from any summary of it, which is how we check everything we publish. It is a preliminary ruling, not a final judgment, and it decides a motion rather than the case.

What did the Iowa court actually decide?

That the federal commodities licence Kalshi holds does not switch off Iowa's gambling code.

Kalshi is certified as a Designated Contract Market and argued that the Commodity Exchange Act, as amended by Dodd-Frank, gives the Commodity Futures Trading Commission sole authority over its event contracts. Judge Locher rejected that at the foundation. Sports-related event contracts, he held, are not "swaps" under the statute, so they never enter the CFTC's exclusive jurisdiction in the first place. Express preemption, field preemption and conflict preemption all failed on that same point.

On the history, the order is blunt: "Gambling was not a focal point for Congress when it amended the Commodity Exchange Act through the Dodd-Frank Act." At the time Dodd-Frank passed, the judge noted, sports gambling was illegal in all but four states. "In context, there is no reason why Congress would have given much attention to gambling when it enacted the Dodd-Frank Act."

On whether Congress meant to take the whole subject away from the states, the order is shorter still. The presumption against preemption applies "when the field in question is traditionally reserved to the States," and, Locher wrote, "Gambling is clearly such a field."

Kalshi also argued that complying state by state was impossible. The court's answer: "This may be inconvenient for Kalshi, but it is not impossible. Indeed, other companies engaged in sports gambling already do this."

Can I still trade on Kalshi in Iowa?

The order does not close any account, and nothing in it requires Kalshi to stop trading in Iowa. What changed is the protection it asked for and did not get.

Two details in the ruling matter to anyone holding an Iowa position. First, on standing, the court recorded that Attorney General Brenna Bird "has not disavowed" an intention to investigate Kalshi, "instead merely promising not to open one before Kalshi's Motion for Preliminary Injunction is decided." That motion has now been decided. Second, the court found Kalshi's fear of prosecution credible on the face of the statute, noting that "a reasonable person could view the company's business as including activities that are proscribed" by Iowa Code section 725.7(1).

Kalshi told the court that an enforcement action would force it to close open Iowa positions before they settle, and that a user holding a contract that had risen in value would get back only the original purchase price. The judge was unimpressed with how that case was made, calling the filings "heavy on hyperbole regarding irreparable harm" while providing "virtually no concrete information about the extent of the risk." He also declined to treat the cost of geofencing Iowa as a reason to intervene: "this is a problem of the company's own making. It should have proceeded with greater caution."

Why does a prediction-market ruling matter to sweepstakes players?

Because it is the same argument, and this time a federal judge tested it against the exact Iowa provision that has sweepstakes written into it.

Kalshi does not sell Sweeps Coins and is not a sweepstakes casino. What it was asking a federal court to say is that a federal licence beats a state gambling statute, which is the shape of every legal theory that would let a dual-currency operator keep serving a state that has closed the door.

The provision matters here. The order records that the Racing and Gaming Commission "ha[s] the authority to pursue action against Kalshi for engaging in gambling or sports wagering without an appropriate license" under Iowa Code section 99F.4(13), even though it doubted Kalshi had standing to sue that agency at all. Section 99F.4(13) is the subsection Iowa rewrote this year. Senate File 2289, effective July 1, 2026, amended it to cover cease-and-desist orders and injunctive relief against anyone offering "games of chance, gambling, sports wagering, or illegal sweepstakes in this state without holding an appropriate license issued by the commission." A federal judge has now written down that this power reaches unlicensed operators and is not displaced by federal commodities law.

Iowa has still not used it against a sweepstakes brand. That is the gap our Iowa legality page records and the point of our read of the cease-and-desist statute itself; when we last went through the operator documents, 11 of the 12 we could read still listed Iowa. Nothing in this order changes that. What it does is remove one of the arguments an operator could have raised after a letter arrived.

Which states have ruled against Kalshi so far?

Seven rulings in this line landed before Iowa, all of them against the exchanges, and one federal appeals court has gone the other way on the underlying question.

The Iowa order itself leans on rulings in Maryland and Connecticut, and quotes the Connecticut court's line that "[t]he fact that Connecticut law imposes an additional regulatory requirement on Kalshi does not, without more, establish a conflict with federal law." Here is where the argument has been tested elsewhere, each row as our own read of that decision recorded it:

The one court that has gone the other way is the Third Circuit, which held in KalshiEX, LLC v. Flaherty that all event contracts are swaps under the Commodity Exchange Act. That split is why nobody should call this settled. A separate federal filing we read this week records that the consolidated Kalshi appeals in the Sixth Circuit were fully briefed and argued on July 30, 2026, so the first appellate answer with real reach is pending rather than delivered. That filing is Robinhood's agreement to close its Michigan sports event contracts, signed four days before this order.
