🔥 Trending DDHQ House and Senate Forecast: What the Experts Are Predicting

Decision Desk HQ (DDHQ) has released its official forecast for the 2026 U.S. midterm elections, offering projections for the control of both the House of Representatives and the Senate ³⁴⁹.

DDHQ's 2026 Forecast Overview

According to DDHQ's latest analysis as of July 2026, Democrats are favored to win the House of Representatives, while the Senate is projected to result in a 50-50 partisan split ¹²⁶. This forecast is based on a model that incorporates political data, election polling, and prediction markets, with daily updates ³⁹.

House of Representatives Projections

DDHQ's forecast indicates that Democrats are in a strong position to secure a majority in the House. Specifically, the forecast projects Democrats to win the House with a 227-208 majority ⁶. This suggests a "blue wave" scenario for the House, potentially flipping several Republican-leaning seats to Democratic control ⁸.

Senate Projections

The Senate, however, is expected to be much more competitive. DDHQ's model forecasts a 50-50 partisan split in the Senate ¹²⁶. In such a scenario, the Vice President's party would hold the tie-breaking vote, effectively giving that party control of the chamber ⁶. While some reports suggest Republicans might narrowly retain control in a 50-50 split with the Vice President's tie-breaking vote ⁶, the overall picture paints a highly competitive race ¹².
