The Washington State Court issued a preliminary injunction against Kalshi, ruling that it violated state gambling laws and that federal commodity trading laws do not take precedence over state law

On July 20, the King County Superior Court in Washington State approved the preliminary injunction motion against KalshiEX, LLC (Kalshi), ruling that Kalshi's activities constitute illegal actions in violation of Washington State's gambling laws, and determined that the federal Commodity Exchange Act does not take precedence over state gambling laws.

This ruling is an important precedent in the jurisdictional dispute between state regulatory agencies and federal regulatory prediction market platforms, following accusations from the CFTC chairman of illegal enforcement actions by states against federally regulated exchanges. The court made the ruling after reviewing multiple materials, including the oral arguments from July 10. The case number is 26-2-10264-3 SEA.
