Polymarket’s $5M Market Puts Democrats Ahead in 2026

Midterm prediction market odds now favor Democrats in the Senate. Polymarket’s contract on which party will win the Senate in 2026 now shows the Democratic Party at 63% and the Republican Party at 39%. The market has drawn about $5.4 million in total trading volume. That 63% is a live, tradable price. It is not a poll result, a forecast model or a guaranteed outcome. The shift is notable.

The number now reflects where traders are willing to put money on which party controls the chamber after the 2026 midterms.
