California Governor Gavin Newsom has introduced one of the nation’s strongest state‑level crackdowns on insider trading within prediction markets, issuing an executive order that bars state officials from using nonpublic information to profit from wagers on political, economic, or military events. The order, which took effect immediately, extends existing ethics rules to cover platforms such as Kalshi and Polymarket, where real‑world event betting has grown rapidly.
Newsom framed the action as a necessary response to rising concerns that individuals with access to sensitive government information have used it to place unusually well‑timed bets—sometimes ahead of major geopolitical developments. The new rules prohibit not only direct participation but also indirect profiteering through family members, business partners, or intermediaries.
The governor emphasized that public service must remain free from financial conflicts, saying the state cannot risk even the appearance that officials might leverage privileged information for personal gain. His move comes as federal lawmakers debate broader restrictions on prediction markets, particularly those involving national security or government decision‑making.
California’s action signals a growing recognition that prediction markets, while innovative, require guardrails when public trust and sensitive information are at stake.
