KalshiEX v. Bird 8th Circuit briefing concludes (prediction market preemption appeal)

Briefing is scheduled to conclude on December 6, 2026 in Kalshi's appeal before the U.S. Court of Appeals for the 8th Circuit. The case asks whether federal commodities law overrides state gambling law for sports event contracts. No specific coins are involved.

What is happening

KalshiEX LLC v. Bird is Kalshi's appeal from Iowa to the 8th Circuit. The central question is whether the Commodity Exchange Act preempts state gambling law as applied to sports event contracts, which would place such markets under the exclusive oversight of the CFTC. According to a complaint filed by Novig's exchange operator, Ludlow Exchange LLC, briefing in the appeal is set to wrap up on December 6.

The deadline is relevant beyond Iowa. On October 16, Ludlow Exchange sued Missouri officials in the Eastern District of Missouri, and the exchange behind Crypto.com's prediction market platform, North American Derivatives Exchange Inc., filed a similar suit in the Western District. Both challenge Missouri Attorney General Catherine Hanaway's demand, sent in September to six operators, that they stop offering sports event contracts in the state or obtain a state license and pay its taxes and fees.

Novig is asking for a preliminary injunction to hold the status quo while the 8th Circuit, which covers Missouri, weighs the same preemption question. Federal appeals courts have so far split: the 6th Circuit ruled against Kalshi in appeals from Ohio and Tennessee, while the 3rd Circuit sided with Kalshi in New Jersey.

Why it matters

The preemption question determines whether prediction market operators answer to a single federal regulator or must also comply with state gambling licensing, taxation and age rules. The outcome could affect how crypto-linked and regulated exchanges structure their sports contracts across many states, including those already taking enforcement action.

For traders and users of these platforms, the end of briefing is a procedural step rather than a ruling, and the court's decision will come later. It is still a useful marker: the pending 8th Circuit appeal is the basis for Novig's request that Missouri courts pause enforcement in the meantime. Watch for any scheduling of oral argument, the district courts' handling of the injunction requests, and further rulings from other circuits.
