Incumbent Senator Lindsey Graham commands 84% trader consensus in the South Carolina Republican Senate primary on June 9, driven by his incumbency advantage, $20 million fundraising lead, and endorsements from Donald Trump and Governor Henry McMaster, reinforcing his path-to-victory in the GOP stronghold. Challenger Mark Lynch holds 16% after Paul Dans, Project 2025 architect, withdrew on April 10 and endorsed him, consolidating anti-incumbent votes in the six-way field amid polls showing Graham's soft support but primary leads. Low odds for Paul Dans (0.5%) and Thomas Murphy (0.2%) reflect their minimal fundraising and traction, with trader sentiment prioritizing Graham's institutional edge despite conservative media buzz around Lynch.

The resolution source for this market will be the first announcement of the results from the South Carolina Republican party, however an overwhelming consensus of credible reporting may suffice.
