**In the 2026 Senate elections held November 3, final unofficial tallies show only Alaska and Mississippi with margins narrow enough to potentially resolve within 1%.** Alaska features Democrat Mary Peltola at 48.2% versus Republican incumbent Dan Sullivan at 47.9% (0.3-point gap, ~70-76% of expected vote reported). Mississippi shows Democrat Scott Colom at 49.1% against Republican Cindy Hyde-Smith at 48.8% (0.3-point gap, ~95-97% reported). Both races remain uncalled as counting continues. All other contests finished with larger spreads, including Iowa (D+4.1), Ohio special (D+4.8), Kansas (D+5.0), South Carolina (D+4.4), Florida special (R+2.9), and Louisiana (R+1.8). Democrats secured majority control through seven flips amid broader vote shifts, with trader focus now on certification timelines and any late adjustments in these two states.
