# Crypto prediction markets are turning into dangerous national security risks, and Congress wants to ban them

-   Analysts at Bubblemaps say a cluster of 80 highly accurate bets on U.S. military actions against Iran on the Polymarket platform are so precise that “luck alone cannot explain” the results.
-   Bubblemaps’ CEO warns that adversaries could mine prediction markets for clues to U.S. war plans, turning them into tools of intelligence and information warfare and potentially endangering lives.
-   The revelations come as lawmakers push the DEATH BETS Act to ban war-related contracts and as Polymarket touts new Chainalysis-backed oversight, even as it denies tolerating insider trading and says it uses AI and blockchain forensics to flag suspicious activity.
