Hawaii will enforce a law that bans cryptocurrency ATMs and kiosks, becoming the fourth U.S. state to impose a full ban after Minnesota, Tennessee and Indiana, Cointelegraph reported. The state legislature passed House Bill 1642 in May, and Governor Josh Green signed it in July. The law prohibits owning, operating or managing kiosks that take U.S. dollars from customers and convert them into digital assets.

Nine Democratic U.S. senators urged the Commodity Futures Trading Commission to ban prediction-market contracts tied to wildfires, saying such betting could incentivise arson, enable insider trading and undermine public safety. The senators cited Polymarket taking in more than $1.2 million in bets linked to California wildfires in 2025 and said other new platforms also allow wildfire wagers. Their push comes as prediction markets expand and face rising legal and political pressure over regulation.
