2026 Senate Race Odds Monitor

Data from Kalshi & Polymarket prediction markets. Odds are volume-weighted (last 7 days) mid-prices where both sources available. All 35 Senate races on the 2026 ballot (including the Ohio and Florida specials) are checked every run. The table lists those where neither side is at 90% or more; a race that leaves comes back once it is under 89%. Seat count = 34 Dem seats not up in 2026 + 12 Dem-side races off the table (CO, DE, GA, IL, MA, NC, NH, NJ, NM, OR, RI, VA) = 46 base; 12 Rep-side races are off the table. 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.
