About the West Virginia Senate Race
The markets price this race at party level — Democratic vs Republican — rather than by individual candidate; candidate-level markets typically appear after the primaries decide who is running. Election Day is November 3, 2026. This market is scheduled to close around 2027-11-03, settling when the winner is official.
Market Odds vs Polls
Polls measure who people say they support; prediction market odds measure where traders put real money. Polling averages update every few days or weeks, while market prices react to news within minutes — including primary results, debate moments, and fundraising reports. Markets also price primary races and nominee fields before pollsters survey them. Neither is infallible: polls carry sampling error, and thin markets can be moved by a few large trades. Historically, market prices in aggregate have been well-calibrated — a 70% favorite wins about 70% of the time.
