South Carolina Senate market prices Graham at 86c on both venues, far ahead of tight polls

Lindsey Graham is the clear favorite in prediction-market pricing for South Carolina’s 2026 Senate race, despite public polling described as nearly even. According to Action Network, Graham contracts stand at 86c on both Polymarket and Kalshi against Catherine Andrews.

Andrews is priced at 16c on Polymarket and 15c on Kalshi. The two venues therefore present much the same view of the contest, with only a small difference in her quoted price.

Markets and polls offer different signals

The public polls cited in the report show a near-tied race rather than the decisive advantage suggested by the market prices. That contrast is the central question for readers assessing the contest: both platforms strongly favor Graham, while the reported polling picture is substantially more competitive.

The supplied material does not identify the polls, their fieldwork dates or their margins of error. It also provides no trading-volume or liquidity figures, limiting any assessment of what accounts for the divergence or how firmly those prices are supported.

What it means for prediction markets

• Cross-platform agreement: Graham’s identical 86c quotes show that the strong preference for him is not confined to one venue.
• A polling contrast, not a direct equivalence: Election contracts price an outcome, while polls measure voter support; a close polling margin does not itself establish equal chances of victory.
• Limited evidence for explaining the gap: Without the underlying polling details and market activity, the reported snapshot cannot establish whether prices or polls better capture the race.
