NBC tops election night ratings as Democratic gains boost viewership

The 2026 midterm elections produced a strong result for Democratic candidates, and that political shift drove record television interest on election night. Preliminary data from Nielsen indicates NBC held a commanding lead in primetime ratings on Tuesday evening. Analysts believe the margin is large enough that the network will remain on top even after final rating adjustments are completed.

This outcome represents a major change for NBC compared to the 2022 cycle, when the network placed fourth among the six most-watched news organizations. The station also captured the most-watched live stream of the evening with its 'Kornacki Cam.' This feed focused solely on data analyst and video board operator Steve Kornacki.

According to Nielsen fast national ratings, which include out of home viewing, NBC averaged 6.8 million viewers during the primetime block. ABC followed with 5.12 million viewers. The three major cable news channels were nearly tied, with CNN at 4.159 million, MS NOW at 4.156 million, and Fox News at 4.04 million. CBS trailed these groups with 2.73 million viewers.

If these preliminary figures stand, NBC will be the first broadcast network to lead a federal election night in total viewers since the 2012 presidential election. The combined audience across the six reported networks reached 27.05 million viewers. This number exceeds the final 12-network total of 25.43 million recorded for the 2022 midterms, though it falls short of the 36.11 million viewers seen across 11 outlets in 2018.

NBC also led in the core advertising demographic of adults aged 25 to 54, averaging 2.93 million viewers in primetime. ABC ranked second in this group with 1.71 million viewers, followed by CNN at 1.55 million. Fox News, CBS, and MS NOW were closely clustered with 800,000, 771,000, and 764,000 viewers, respectively. Fox Business, which simulcast the Fox News feed, drew 323,000 total viewers and 77,000 in the 25 to 54 age bracket.

NBC News reported that the live stream of the Kornacki Cam generated 29 million views across all platforms. This total included 6.1 million views on YouTube, where the stream peaked with approximately 300,000 concurrent viewers between 8:30 and 11:30 p.m. Eastern Time. The updated data was released on November 4 at 1 p.m., incorporating out of home ratings from Nielsen.
