**Trader consensus centers on 900K-975K total votes (70.5%) for the November 3, 2026, Arkansas U.S. Senate election because the race remains non-competitive.** Republican incumbent Tom Cotton holds a double-digit polling lead over Democrat Hallie Shoffner, with forecasts projecting a wide margin consistent with the state's recent federal results. Arkansas midterm turnout has historically tracked lower than national averages, with the 2022 general election at roughly 41.5% of voting-eligible population. Primary data from March 2026 showed solid Republican participation but limited overall engagement, while Democratic primary turnout rose in some states without translating into general-election momentum here. Early voting begins October 19 with no major late-breaking catalysts or high-profile mobilization efforts reported. The distribution of probabilities around the 900K-975K range reflects traders' assessment of these structural factors and base rates for a low-salience midterm contest in a solidly Republican state.
