A resolution amending rule XXXVII of the Standing Rules of the Senate to prohibit Senators from trading on prediction markets.

This resolution amends Senate rules to ban Senators from trading on prediction markets, which are financial agreements tied to specific future events like election outcomes or policy decisions. The change directly affects all Senators by prohibiting them from entering into contracts that involve buying or selling based on whether a particular contingency occurs, with the only exception being standard insurance policies. While the primary effect is an internal rule change for the Senate, the bill also expresses the Senate's preference that other government branches adopt similar restrictions.
