**Recent primary turnout of about 150,000 ballots (roughly 55% of registered voters) and historical midterm patterns anchor trader expectations for the November 3 general election.** Wyoming’s voting-age population stands near 454,000, with registered voters around 274,000; past midterm generals have produced turnout in the low-to-mid 40% range of eligible voters, typically yielding 190,000–230,000 ballots when no high-profile presidential contest drives participation. The 2026 Senate race is an open-seat contest between Republican Harriet Hageman and Democrat James Byrd in a state that has not elected a Democrat to the Senate since 1970. It coincides with an open gubernatorial race and state legislative contests, which can modestly lift baseline midterm participation but rarely approach presidential-year levels. No major late-breaking events, scandals, or national surges have altered the low-salience environment since the August primaries. Market pricing therefore concentrates probability in the 170K–230K bands, reflecting the expectation that turnout will track recent midterm baselines without unusual mobilization on either side.
