Scott Colom holds a narrow but expanding lead in unofficial tallies from the November 3 Mississippi Senate election, with roughly 97 percent of votes counted and 12,000–20,000 affidavit ballots still under review. Traders have priced his victory probability near 99 percent because the remaining ballots have trended toward him in recent county reports, consistent with higher Democratic turnout patterns observed statewide. The contest features an independent candidate drawing a small share of the vote and occurs amid broader midterm shifts that have already flipped multiple Republican-held Senate seats. A Hyde-Smith reversal would require the uncounted ballots plus any certification disputes to produce a decisive shift in her favor, an outcome markets currently view as unlikely given the trajectory of the count.
