Kalshi

The event resolves based on the margin of victory for either Darline Graham or Ralph Norman in the 2026 South Carolina Republican Senate special primary runoff. The margin of victory is calculated as the vote share of the winning candidate minus the vote share of the runner-up; if a candidate loses, the margin is negative, and a tie results in a zero margin. Each market corresponds to a specific percentage range for a candidate's margin of victory, inclusive of the lower bound and exclusive of the upper bound, with no rounding applied. If a candidate runs under multiple parties or listings, all votes for that candidate are summed. The ranges for both candidates are structured identically, spanning from 0% to over 24%, ensuring comprehensive coverage of possible outcomes.

The dynamics of the runoff could cause this market to shift independently from traditional surveys, making it a complementary rather than identical indicator of likely outcomes.
