Overview
- Federal regulators asked a U.S. court to stop Arizona from enforcing its gambling laws against Kalshi, arguing that contracts that pay on future outcomes are swaps under the Commodity Exchange Act and fall under the CFTC’s exclusive authority.
- A federal judge in Phoenix denied Kalshi’s separate bid to pause the state case, citing the Anti‑Injunction Act that generally bars federal courts from halting ongoing state prosecutions, and the arraignment remains set for April 13.
- The CFTC’s move to sue states is unusual, and a scholar of the agency said he was not aware of any prior instance in the CFTC’s 50‑year history where it sued a state to protect its jurisdiction.
- Courts have reached conflicting conclusions, with a recent Third Circuit decision favoring Kalshi’s federal preemption claim and other courts allowing state enforcement actions to proceed.
- The stakes are significant for traders and platforms because a win for federal preemption could enable nationwide trading under one rule set, while losses could force these products into state gambling regimes or out of key markets.
