Trader sentiment on Idaho's 2026 Senate election turnout centers on historical midterm patterns, where participation typically falls well below the 64% registered-voter rate seen in the 2024 presidential contest. Recent primary turnout reached 30.1% in May—above the post-2000 median—while ongoing population inflows and roughly 969,000 registered voters provide upward pressure. The contest between incumbent Jim Risch and independent challenger Todd Achilles has produced mixed polling, including one survey showing a narrow Achilles lead, yet overall forecasts remain strongly Republican, limiting expectations of unusually high mobilization. These factors keep leading probabilities clustered in the 560k–680k ranges, with notable weight on sub-520k outcomes reflecting baseline midterm dynamics and the absence of late catalysts that could drive separation.
