House passage of the Stop Insider Trading Act in July 2026, which bars new individual stock purchases by members and their families but permits retention of existing holdings, has not altered trader expectations for a stricter prohibition before 2027. The measure advanced on a 232-198 vote amid partisan splits and Democratic criticism that it falls short of a comprehensive ban. In the Senate, companion legislation remains stalled in committee or without a firm floor schedule, reflecting institutional resistance, competing legislative priorities in the 119th Congress, and procedural hurdles that have historically delayed ethics reforms. These factors sustain the prevailing view that enactment of a full congressional stock trading prohibition by December 31, 2026, faces significant barriers.
