Kalshi, Polymarket Predictors Favor Democrats to Sweep 2026 Midterms

Prediction markets, which have proven to be somewhat reliable when it comes to political outcomes, are signaling a clear advantage for the Democratic Party on the eve of the upcoming midterm elections, when all 435 seats in the U.S. House of Representatives and 35 of the 100 seats in the U.S. Senate will be contested.
