In a recent ruling, a federal judge in Arizona has granted a temporary restraining order, preventing the state from bringing criminal charges against Kalshi, a prediction market provider. The decision comes in response to a motion filed by the Commodity Futures Trading Commission.
District Judge Michael Liburdi stated that the CFTC has demonstrated a strong likelihood of succeeding in its claim that Arizona's gambling laws are preempted by federal law. As a result, Arizona is temporarily restrained from enforcing its gambling laws against Kalshi. The CFTC has argued that prediction markets fall under its regulatory oversight, and that federal law takes precedence over state law in this matter.
This development is the latest in an ongoing dispute between states and the CFTC over the regulation of prediction markets. The ruling has been welcomed by the CFTC, with Chair Michael Selig stating that it sends a clear message against the use of state criminal law to intimidate companies that comply with federal regulations.
