Political risk guru Ian Bremmer has banned Eurasia Group employees from betting on Polymarket, Kalshi, and other prediction markets. Bremmers, who advises institutional investors and sovereign wealth funds, called prediction markets'more dangerous than social media for democracy' as they represent a conflict for objective analysis on global affairs. This comes as Senators Adam Schiff (D-CA) and John Curtis (R-Utah) introduced legislation targeting prediction market sports betting at the federal level, which is directly targeted at Kalsh and Polymarket’s U.S. platforms. The updated rules define three types of prohibited insider trading: trading on stolen confidential information about an event’�s outcome, and anyone with enough influence to affect the outcome of an event is barred from trading on it.
