The House passage of the Stop Insider Trading Act in July 2026 advanced a measure restricting congressional stock purchases, yet Senate action remains stalled amid competing legislative priorities and procedural hurdles. Earlier Senate versions introduced in 2025 have lingered in committee without floor votes, reflecting institutional resistance and the challenges of securing sufficient support in a divided chamber. With limited session time remaining before 2027 and no recent breakthrough announcements or votes, traders assign low odds to full enactment and presidential signature within the window. This consensus aligns with historical patterns where ethics reforms on member trading have repeatedly advanced in one chamber but faltered before becoming law.
