Andrews takes market lead as South Carolina Senate odds shift

Polyguana reports Democrat Annie Andrews now leads the South Carolina Senate market at 58.5 percent against Republican Darline Graham Nordone at 41 percent, a 38 point move in 24 hours in a race priced at 70 percent for the Republican earlier on Election Day. The board now counts the seat as a lean Democratic flip among the races deciding Senate control.

Democrat Annie Andrews has moved ahead in the South Carolina Senate prediction market, reaching 58.5 percent against Republican Darline Graham Nordone at 41 percent, according to Polyguana.

The update, published Nov 3, 2026, at 8:15 PM ET, puts the contest among the races that could determine Senate control.

Election Day pricing reverses

Polyguana described a 38 point move over 24 hours. Earlier on Election Day, the race had been priced at 70 percent for the Republican, marking a substantial reversal in the market’s assessment.

The board now classifies the seat as a lean Democratic flip, according to Polyguana. That designation reflects market pricing rather than an election result; the supplied summary includes no vote totals or outcome call.

What it means for prediction markets

  • Control implications: The board’s shift toward a Democratic flip changes its assessment of one of the contests deciding Senate control.
  • Rapid repricing: The reported 38 point move in 24 hours underscores how sharply expectations have changed during Election Day.
  • Evidence limits: The summary provides current prices and an earlier Republican probability, but no explanation for the move or vote-count data against which to assess it.
