Democratic control of the Minnesota State Senate holds an 89% implied probability in the market, reflecting forecasts that project Democrats retaining or expanding their current 34-33 majority across all 67 seats on the November 3, 2026 ballot. Recent legislative models show Democratic advantages in a D+12 environment relative to the 2024 presidential vote, with expected seat totals centering around 42 and only a handful of toss-up or lean-Republican districts remaining competitive after August primaries. Republicans' 12% pricing aligns with limited projected gains in greater Minnesota seats, while the overall map favors Democratic performance in suburban and urban-leaning areas. Upcoming factors include final voter turnout patterns and any late shifts in the three closest races.
