This article has been updated to include details about the race in Maine's 2nd Congressional District.

While control of the House of Representatives following the 2024 elections has yet to be determined, Republicans are feeling confident that they will hold onto this chamber as well, giving them control of the White House, the Senate, and the House, just as was the case in 2016. On Tuesday night, Republicans seized control of the Senate, thanks to Sen-Elect Bernie Moreno's win in Ohio, after he unseated Democratic Sen. Sherrod Brown. 

During his victory speech in the early hours of Wednesday morning, President-Elect Donald Trump was joined on stage by Speaker Mike Johnson (R-LA), among many others, as he expressed confidence that the party would maintain control of the chamber.

Throughout Wednesday and Thursday, Republican House leaders have expressed confidence about their chances, including Rep. Richard Hudson (R-NC), this cycle's chairman of the National Republican Congressional Committee (NRCC).

It's not just Republican lawmakers, though, who are feeling so confident. On Thursday afternoon, with Republicans just five seats away from earning the majority, Decision Desk HQ predicts that there is an 85.1 percent chance that they keep control of the chamber. While those numbers have been changing, the edge remains with Republicans. Polymarket gives Republicans a 97 percent chance.

And yet despite the odds against them, Democrats have been expressing a shocking amount of confidence as well, as House Minority Speaker Hakeem Jeffries (D-NY) made clear on Wednesday. 

Both parties lost and flipped House races, with Republicans flipping some key races. 

Among those flips officially called by Decision Desk HQ, include:

Although the races have yet to be called in these districts, Republicans are leading in these races as well, with most of them taking place in California:

Several other Republican incumbents also held on, including the following who were expected to be in tight races:

Although Decision Desk HQ called the race out of Maine's 2nd Congressional District on Wednesday afternoon in favor of Democratic Rep. Jared Golden, Republican Austin Theriault, with a statement highlighting how "historically" close it is. 

"Given that this is the closest race in modern Maine history, we must ensure a full, accurate count," Theriault campaign manager Shawn Roderick said in a statement. "Despite being significantly outspent, this race is still extremely close. We must work together to ensure the Mainers' voices are heard and the final result reflects the will of the people."

During the 2022 midterm election, when Republicans performed much worse than expected, it took several more days for such a call to be made, with California House races once again delaying the call but also bringing wins for Republican members. 

Republicans won all three chambers in 2016 as well, though unlike 2016, Trump also won the popular vote, which a Republican has not achieved since 2004.
