Democratic prospects for regaining House control in the November 2026 midterms represent the central driver behind the 62% implied probability. Generic ballot polling averages show Democrats leading by roughly six to seven points, consistent with historical midterm patterns favoring the opposition party. Republicans currently hold a narrow majority, but analysts and prediction markets assign Democrats a strong chance of securing the 218 seats needed for a majority. Multiple articles of impeachment have already been introduced in the current Congress. Democratic leaders have indicated that investigations into administration-linked entities would precede any floor vote if the chamber flips, though a successful House majority on articles remains possible before the term concludes in 2029. Senate conviction thresholds introduce separate uncertainty.
