U.S. District Judge Michael Liburdi blocked Arizona's criminal case against Kalshi, a prediction market operator, citing federal law's authority over state gambling laws.

Letitia James has filed lawsuits against Coinbase and Gemini in Manhattan, alleging their prediction markets operate illegally without licensing.

Minnesota has enacted a state ban on prediction markets, criminalizing creation, operation or advertising of such markets starting Aug. 1.

Kalshi has started collecting job information to screen markets at heightened risk of manipulation and is rolling out a risk-scoring system plus 24/7 whistleblower channel. The measures aim to curb insider trading after a string of cases across Kalshi and Polymarket, including investigations into George Santos and a Google insider-trading case.
