Mississippi leads trader consensus at 96.7% as the closest 2026 Senate race due to its sub-1% unofficial margin between Democrat Scott Colom and Republican incumbent Cindy Hyde-Smith after nearly all votes were tallied. Pre-election forecasts rated the contest Likely Republican, yet late-counted provisional and absentee ballots—trending Democratic—produced an unexpectedly tight result near 0.5 points, with Colom ahead by roughly 4,700 votes. Certification deadlines through November 13 and the absence of an automatic recount keep the final margin fluid. Other races such as Alaska remain competitive but show wider spreads in current tallies. Shifts from remaining certifications or court challenges in Mississippi, or narrower outcomes elsewhere once fully resolved, represent the main paths that could reorder the market.
