Close Red-State Polls Haven’t Shaken Traders’ Faith in Graham and Moody

Republicans have a polling problem in two states they ordinarily expect to win.

Still, prediction markets traders think they will hold both.

A New York Times/Siena University poll released Wednesday found Republican South Carolina Sen. Darline Graham and Democrat Annie Andrews tied at 48%. In Florida, Republican Sen. Ashley Moody led Democratic state Rep. Angie Nixon 50% to 44%, a narrower margin than the GOP’s recent statewide victories.

Kalshi is considerably more confident in the Republican outcomes. Graham is trading at 72% with $7.5 million in volume, while Moody is at 90% with $3.2 million traded, as of Thursday night.

It is not all sunshine in the South, however. The South Carolina market has moved as Graham’s probability is down 15 percentage points from the 87% recorded entering October. But traders have reduced their confidence without making the race a coin flip.

Florida presents a different question. Moody still leads the new poll by six points, so the disagreement is not over which candidate is ahead. It is over how secure that advantage should make her with five days remaining before Tuesday’s 2026 midterm elections.

South Carolina: tied polls, a Republican market favorite

The Times/Siena survey gives Andrews a credible route to an upset.

The pediatrician leads Graham 57% to 37% among independent voters and draws support from 7% of Republicans. She also holds a narrow advantage on which candidate would do what is best for ordinary South Carolinians, 49% to 46%.

Graham’s experience is another vulnerability. The poll found 51% saying she lacked the experience to be an effective senator, while 54% said Andrews had the right experience. Graham was appointed after her brother, Sen. Lindsey Graham, died in July, and she is now seeking a full term.

The survey interviewed 707 South Carolina voters Oct. 19-26 and carries a 4.3-percentage-point margin of sampling error among likely voters. The rounded result is a tie, with Graham ahead by less than one point before rounding.

Other recent polling also puts her under pressure, although not every survey shows a dead heat. A South Carolina Policy Council poll found Graham ahead 47% to 46%, while a Citadel survey gave her a 43%-39% advantage.

That leaves traders weighing a Republican who has generally retained at least a small polling edge against a Democrat who has made a normally reliable GOP seat genuinely competitive.

At 72%, Kalshi is pricing Graham as the clear favorite, not treating the polling warnings as irrelevant.

Florida: a narrower Republican lead is still a lead

Moody’s market position is substantially stronger.

The Florida poll interviewed 813 voters Oct. 19-25 and has a 3.9-percentage-point margin of error among likely voters. Approximately 5% were undecided or declined to answer.

Nixon’s strength among independents helps explain why the race is closer than Republicans might prefer. She led Moody 52% to 38% with that group, according to reporting on the survey. 1176

But Nixon still trails statewide. CNN’s analysis described Florida as a second-tier Democratic target, contrasting it with the effectively tied contest in South Carolina.

That distinction matters when interpreting the prices. A six-point lead late in a campaign can coexist with a high probability of winning. A tied poll alongside a 72% probability requires more weight on evidence beyond that individual survey.

Why traders may be more confident than the polls look

The first explanation is the difference between a vote-share estimate and a win probability.

A poll asks whom respondents support. A market asks whether a specified candidate will win. Moody does not need 90% of the vote to justify a 90% win probability; she needs traders to believe there is only a relatively small chance she finishes behind Nixon.

South Carolina is the sharper test because the latest high-profile survey provides almost no separation between the candidates. Several factors could explain the market’s Republican lean, but the quoted prices alone do not reveal what individual traders are thinking.

State history may carry weight beyond the latest survey

Both states have strong recent Republican records. South Carolina has not elected a Democratic senator this century, while Florida’s recent Republican statewide victories have been by double-digit margins.

Traders may expect some voters to return to familiar partisan choices or to weigh those historical results more than a single close survey.

That is a plausible interpretation of the prices, not proof that the historical pattern will hold. Andrews’ support among independents and Republican defectors is precisely the kind of evidence that could signal a break from it.

Prices can be wrong, too

The reverse possibility deserves equal attention: Traders may be too slow to abandon assumptions about Republican strongholds.

Graham’s decline from 87% to 72% shows that her market has become less confident. It does not establish that the latest price fully accounts for the risk.

The $10.7 million traded across the two races also should not be mistaken for a representative vote. Volume counts trading activity, can include repeated transactions by the same participants and does not reveal how many independent judgments underpin the price.

Competitive does not mean Democrats are favored

These races illustrate a distinction running through the closing Senate campaign: A state can become an expensive, uncomfortable Republican defense without becoming the most likely Democratic pickup.

South Carolina now offers Democrats a plausible additional route. Florida’s six-point Republican lead keeps it a more difficult opportunity, even if Nixon is performing better than recent Democratic statewide candidates.

Kalshi’s prices preserve that hierarchy. Graham is vulnerable but favored. Moody is a much stronger favorite despite a narrower-than-usual Republican polling margin.

The key word is probability. The polls show why Republicans cannot dismiss either contest. The markets show that traders still expect the GOP to survive them, and South Carolina will provide a particularly clear test of how much confidence a red-state history deserves when current polling says the race is effectively tied
