House passage of the Stop Insider Trading Act in late July 2026 advanced a measure restricting new individual stock purchases by members, spouses, and dependents, yet the bill faces an uncertain path in the Senate amid a compressed legislative calendar before the 119th Congress concludes. Multiple companion proposals, including S.1879 and the Restore Trust in Congress Act, remain stalled in committee without floor action or whip counts indicating momentum. Senate leaders have historically avoided advancing ethics measures lacking broad bipartisan support, and procedural hurdles such as holds, amendments, or calendar constraints further reduce prospects for enactment by December 2026. Traders price the implied probability of a completed ban before 2027 at just 10.5 percent, reflecting the gap between House progress and Senate gridlock on this issue.
