Democrats' takeover of both chambers of Congress following the November 2026 midterms has elevated the implied probability of impeachment to 68% in trader markets. With House control, Democrats gain subpoena authority and the ability to advance articles by simple majority, enabling inquiries into administration policies, cabinet conduct, and executive actions. Historical precedent of two prior impeachments reinforces expectations that oversight efforts could culminate in formal proceedings before January 2029. Senate conviction remains unlikely given the two-thirds threshold and current seat distribution, which limits removal odds near 17%. Traders weigh these procedural realities against risks of political backlash or focus on investigations rather than immediate votes, while noting scheduled committee transitions in January 2027 as potential catalysts.
