Trend (Dem %)
Data from Kalshi & Polymarket prediction markets. Odds are volume-weighted (last 7 days) mid-prices where both sources available. Seat count assumes Dems hold 34 non-2026 seats + 10 safe holds (CO, VA, RI, OR, MA, DE, NM, IL, NJ, MN) = 44 base. Includes Ohio special election (Vance vacancy). Each race shows its two leading candidates; an independent (Ind) is shown on the side they are more likely to caucus with, and counted on that side. Not financial advice.
