US judge blocks Arizona enforcement against Kalshi contracts
US District Judge Michael T. Liburdi issued a preliminary injunction barring Arizona regulators and prosecutors from pursuing criminal or civil enforcement against Kalshi over sports and event contracts. The judge found the contracts likely qualify as swaps under the Commodity Exchange Act, placing them within the CFTC’s exclusive jurisdiction; Arizona had filed a 20-count criminal information against the company in March.
The injunction temporarily limits Arizona’s ability to enforce state gambling laws against Kalshi’s contracts.
