Polymarket, a leading prediction platform, currently indicates a 75% likelihood that Democrats will secure control of both the House and Senate in the 2026 U.S. midterm elections. As Americans head to the polls, this forecast reflects a significant shift from the narrow Republican majorities in both chambers. The prediction comes amid a backdrop where all 435 House seats and 35 Senate seats are contested. While the Democratic Party needs to gain three House seats and four Senate seats to achieve majorities, the prediction market suggests that such an outcome is increasingly likely.
Key Takeaways

What to Watch
