Democratic control of the House following the November 2026 midterms has elevated trader expectations that articles of impeachment against President Trump will advance before January 2029. With Democrats securing majorities in both chambers effective January 2027, the House can approve resolutions by simple majority, as occurred in Trump’s two prior impeachments. Prediction markets have responded directly to these results, with implied probabilities for House action rising sharply in early November amid expectations of investigations into administration policies and officials. Democratic leaders have emphasized oversight and legislative priorities over immediate impeachment proceedings, and Senate conviction remains structurally difficult. The current 66% Yes price on Polymarket reflects this institutional shift and historical precedent rather than any confirmed timeline or bipartisan consensus.
