California Governor Gavin Newsom has issued an executive order prohibiting state appointees from leveraging non-public information for profit on prediction market platforms. According to NS3.AI, this move comes as lawmakers introduced the PREDICT Act earlier this week, which mandates violators to forfeit profits and incur a 10% penalty. Additionally, Polymarket and Kalshi have implemented stricter regulations as their combined monthly trading volume exceeded $20 billion for the first time this month.
