Polymarket gives Graham an 85% win probability, well above the latest polling where she leads Andrews 48-43 in the most recent Rasmussen survey—a 37-point gap between betting markets and current polls that reflects deep-red South Carolina's structural Republican advantage. Graham won the special GOP primary in August after her brother's death and faces her first general-election debate against Andrews on Oct. 11, a potential inflection point given her stumbles on national security during the runoff when she said "national security is not my thing." Andrews has raised $10.8 million and is pressing the debate challenge heavily, but remains well behind in a state Trump won by 17.9 points.
As of October 14, 2026, the Polymarket odds for South Carolina Senate Election Winner are: Darline Graham Nordone (R): 85%, Annie Andrews (D): 16%. These probabilities are derived from real-money trading and update in real time.
