Graham Nordone's South Carolina Senate primary odds fall to 67% after debate stumble
Darline Graham Nordone's Kalshi odds fell to 68% after she stumbled on a national security question during the South Carolina Republican Senate runoff debate. By August 24, traders had repriced her further to 67% ahead of Tuesday's vote, with Ralph Norman at 33%. The market closed before the actual vote. Graham is backed by President Trump. The contract had traded near 89% as of August 17 before the debate misstep triggered a sharp repricing.
The speed of Graham's collapse from 89% to 67% in a week tests whether Kalshi's political contracts can hold price integrity through live events. Traders who bought near the top are already underwater, and the repricing pattern mirrors Michigan and Wisconsin primaries where certainty met sudden reality.
For Kalshi, the stakes are concrete: each fast collapse weakens the case that these contracts price genuine uncertainty rather than chase headlines. The CFTC's hedging-purpose standard gets harder to defend when capital floods foregone conclusions and then flees at the first misstep. Political contracts need to prove they forecast, not follow, for institutional liquidity to return after November.
