The closely matched Polymarket bins around 2.5M–2.95M votes reflect trader assessments of a low-competition general election in a solidly Democratic state, where incumbent Ed Markey holds a wide lead over Republican John Deaton. A decisive September 1 Democratic primary victory for Markey over Seth Moulton generated limited enthusiasm, consistent with Secretary of State William Galvin’s expectations of standard rather than elevated participation. Typical midterm turnout drop-off, combined with monitoring of early voting volumes and mail ballot return rates, continues to anchor probabilities near historical patterns for similar off-year Senate contests without introducing major catalysts that would widen separation among the leading ranges.
