A 'no-brainer': Senate unanimously bans members and staff from using prediction markets

The U.S. Senate has unanimously passed legislation banning senators and their staff from using prediction markets, marking a significant step in addressing potential conflicts of interest in political betting.

The legislation comes amid growing concerns about lawmakers potentially profiting from insider knowledge through platforms like Kalshi and Polymarket, which allow users to bet on political outcomes and policy decisions.

The ban represents what supporters called a "no-brainer" decision to maintain ethical standards and public trust in government institutions. The unanimous vote demonstrates rare bipartisan agreement on an issue touching both financial ethics and emerging technology platforms.
