Rachel Anderson's commanding 100% implied probability in the West Virginia Democratic U.S. Senate primary market reflects major news outlets' projections of her victory in the May 12, 2026, primary election, where she defeated challengers Thornton Cooper, Jeffrey Kessler, Zachary Shrewsbury, and Rio Phillips based on vote tallies reported shortly after polls closed. This outcome, driven by voter turnout in the low-registration Democratic primary amid West Virginia's Republican-leaning electorate, has solidified trader consensus on her nomination for the general election against incumbent Republican Shelley Moore Capito. While certification by state officials typically follows without issue, a realistic challenge could arise from a legal dispute over provisional or absentee ballots, though historical precedents in uncontested projections show minimal disruption.
