Wyoming’s 2026 Senate contest pits Republican Harriet Hageman against Democrat James Byrd in a solidly Republican open seat. Hageman’s decisive August primary win and universal safe-Republican ratings have produced minimal partisan mobilization or Democratic turnout efforts. Recent midterm general elections in the state generated between 171,000 and 205,000 total ballots, well below the 271,000 cast in the 2024 presidential cycle. Traders therefore place the highest probability on the 190,000–210,000 range, viewing it as the structural baseline once the typical midterm participation drop-off is applied. Limited early-voting data, rural voter patterns, and the absence of competitive catalysts reinforce this positioning ahead of the November 3 election.
