## US Senate Votes Unanimously to Ban Members, Staff From Prediction Markets Over Insider Trading Fears
The US Senate voted unanimously Thursday to prohibit members and staff from trading on prediction markets, escalating scrutiny of the platforms that allow users to wager on real-world events amid concerns about classified information being used for profit.

The 97-0 vote came after a US Army soldier was accused of leveraging military intelligence to profit from trades on these markets, which have grown rapidly in popularity and allow users to speculate on political, economic, and geopolitical outcomes. Senate Majority Leader John Thune sponsored the resolution, which bars all senators and staff from participating in prediction markets going forward. The move signals broader congressional concern about the platforms, which have attracted mainstream attention and trading volume in recent years.

Prediction markets like Kalshi and Polymarket have faced increased regulatory attention as their user base expands. The case involving the US soldier raised alarms about potential exploitation by individuals with access to sensitive government information. The Senate's unanimous action underscores the institution's effort to enforce stricter standards for its own members and employees amid heightened awareness of market vulnerabilities. The ban takes effect immediately, though enforcement mechanisms and potential penalties for violations remain under discussion.
