What prediction markets say about the 2026 US midterm elections — live odds on control of Congress and the Senate races that will decide it. Prices update as real money moves.
A price of 62¢ on Democrats means the market believes there's a 62% chance Democrats take the Senate. Buy Yes at 62¢ and you risk 62¢ to win 38¢ if you're right. Prices move with news, polls, and big bets — which is exactly what our Whale Watch tracks every day.
