The first round of the 2026 special Republican Party primary for the United States Senate election in South Carolina will be held on August 11, 2026, with a potential runoff on August 25, 2026. This market will resolve according to the candidate that wins the most votes in the first round of the special Republican Primary for US Senator from South Carolina. Candidates will be primarily ranked by the number of valid votes received in the specified election. If two or more candidates are tied on valid votes, ties will be broken by alphabetical order of the candidates' first names, as listed in this market group. This market will resolve to the candidate that occupies the highest finishing position after applying this ranking. If the results of this election are not definitively known by December 31, 2026, this market will resolve to “Other.” The primary resolution source for this market will be information from the State of South Carolina, such as official statewide results published by the South Carolina Election Commission (https://scvotes.gov/); however, an overwhelming consensus of credible reporting may suffice.
