US Senate amends ethics rules to ban prediction-market trading

US senators, Senate officers, and Senate employees are now bound to a Senate ethics-rule prohibition on prediction-market betting

Change
The US Senate adopted, by unanimous consent, a resolution amending Senate conflict-of-interest rules to prohibit US senators, and via an adopted amendment Senate officers and employees, from making bets on prediction markets; enforcement sits with the Senate Ethics Committee.
Why it matters
The amended Senate conflict-of-interest rules prohibit prediction-market wagers broadly, not only wagers tied to inside knowledge, creating an ethics-compliance boundary that blocks covered Senate personnel from using prediction-market accounts while in covered roles.
Implications
  • US senators must stop placing prediction-market wagers under the amended Senate conflict-of-interest rules — violations face enforcement by the Senate Ethics Committee.
  • Senate officers and Senate employees must stop placing prediction-market wagers under the amended Senate conflict-of-interest rules — violations face enforcement by the Senate Ethics Committee.
Who is affected
  • US senators
  • Senate officers
  • Senate employees
