Susan Collins is the most-watched GOP-held seat in a state Democrats carry at the presidential level.
North Carolina
An open-seat race after Thom Tillis — perennially one of the closest in the country.
Georgia
Jon Ossoff defends in a true swing state; turnout and candidate quality decide it.
Michigan
Open-seat contest in a Great Lakes battleground that swings with the national mood.
Texas
A potential GOP primary fight plus Democratic recruitment keep this on the watch list.

How to Trade 2026 Senate Control on Polymarket
Aggregate the Map, Not One Poll
Senate control is the joint outcome of a few dozen seats. The chamber market can be mispriced when traders over-weight a single national poll. Build a seat-by-seat view using Cook Political Report ratings, Sabato's Crystal Ball, and the generic ballot average, then compare your implied chamber probability to the Polymarket price.
Trade Catalysts Early
Retirements, primary upsets, recruitment wins, and FEC fundraising deadlines (March 31, June 30, September 30) move Senate odds on a predictable schedule. Polymarket prices often lag breaking news by 24–48 hours, creating windows for traders who process information quickly.

The live odds at the top of this page show Polymarket's current real-money forecast for which party controls the Senate after the 2026 midterms. Prices update every 5 minutes — a 55% reading for one party means traders collectively price a 55% chance that party holds the majority. Because money is at stake, these odds often track Senate control more accurately than individual polls.
About 33 regularly-scheduled Senate seats (the Class II seats) are on the ballot in the November 2026 midterms, plus any special elections triggered by resignations or appointments. Because only a third of the chamber is contested each cycle, control can hinge on just a few competitive races.
The 2026 US Senate elections are held on Tuesday, November 3, 2026, the same day as the House midterm elections and most governor races. Primary dates vary by state and run from spring through late summer 2026.
You buy YES or NO shares on outcomes like "Republican Party" or "Democratic Party" controlling the Senate. Shares trade between $0 and $1, and the price equals the implied probability. If you buy a party at $0.45 and they win control, each share settles at $1.00. You can exit any time before the market resolves.
