Here's what's predicted:

Several exit polls showed that Democrats are favoured to capture the House of Representatives, while both parties are locked in a closely contested, state-by-state battle for the Senate.

Half of voters nationwide said they saw the 2026 midterm elections as an opportunity to rebuke the president, and three-quarters said they are "angry" or "dissatisfied" with the way the country is headed, according to exit polls conducted by SSRS on behalf of a consortium of US media outlets including major television networks and the Associated Press.

Meanwhile, the Guardian cited the Cook Report, which, before elections, classified six Senate races as genuine "toss-ups". The Democrats need to win at least three of these, alongside the other races they are expected to win, it stated.

The report further added that Democrats are favoured in enough House seats to take the chamber without winning any of the 18 seats the Cook Political Report classes as“toss-ups”. If they win every seat they are expected to win, they will comfortably win a majority.

The balance of power now turns on whether Democrats hold the 18 seats rated“lean Democratic”. Republicans, favoured in 195 seats, would need to sweep all 18 toss-ups and flip five Democratic-leaning seats to win.
