CNN's 236% Demo Surge Rattles Fox News' Midterm Ratings Win

By Amara Osei

CNN grew its primetime Adults 25-54 audience by 236% week-over-week in the week of November 2, 2026, per Nielsen Big Data + Panel (a measurement method combining set-top-box data with a viewer sample). That single number tells the story of a midterm election week in which Fox News won the audience war on paper while CNN won it where advertisers pay.

Who won election week?

Fox News held its place as the most-watched cable news network in total viewers on election night and for the rest of the week in primetime and total day, according to TVNewser's cable network ranker. It averaged 1.862 million total primetime viewers and 228,000 A25-54 viewers (the demographic of adults aged 25 to 54 that advertisers price against). That is a gain of 14% in total viewers and 48% in the demo versus the week beginning October 26.

The caveat: Fox News did not win the demo. CNN took first place among the three cable news networks in Adults 25-54 during both primetime and total day, with 373,000 primetime demo viewers — 145,000 more than Fox News. CNN's midterm election day and primetime performance was its best since Election Day in 2024, the report notes.

MS NOW posted the strongest growth of the three. It averaged 1.532 million primetime total viewers and 226,000 demo viewers, up 54% and 95% respectively week-over-week.

In short: Fox News kept the crown on total audience, but the advertiser demo split three ways, with CNN clearly ahead.

What do the week-over-week numbers show?

The election delivered across every network and daypart:

• Fox News primetime: 1.862 million total viewers (+14%), 228,000 A25-54 (+48%)
• Fox News total day: 1.124 million total viewers (+3%), 124,000 A25-54 (+23%)
• MS NOW primetime: 1.532 million total viewers (+54%), 226,000 A25-54 (+95%)
• MS NOW total day: 927,000 total viewers (+49%), 126,000 A25-54 (+80%)
• CNN primetime: 1.339 million total viewers (+117%), 373,000 A25-54 (+236%)
• CNN total day: 749,000 total viewers (+77%), 168,000 A25-54 (+163%)

Those are triple-digit gains for CNN in every measured category. The election did the lifting; the question the data cannot answer is what happens when the results stop.

How did the networks rank across basic cable?

Among all basic cable networks, Fox News remained second in total primetime viewership and third in the demo. During total day, it stayed first in total viewers but dropped from second to fourth place in the demo.

MS NOW held third place in total primetime viewers, moved from sixth to fourth in the demo, and ranked third in both total-viewer and demo measures during total day.

CNN landed fourth in primetime total viewers and second in the primetime demo. It remained fourth in total day total viewers and finished second in that demo as well.

Rankings reward consistency; Fox News' total-day demo slide from second to fourth suggests the halo did not extend far beyond election night.

What does the year-over-year comparison reveal?

The annual comparison is less flattering, and Fox News carries the burden. Year over year, Fox News was down 14% in primetime total viewers, though up 4% in the demo; in total day it fell 20% in total viewers and 6% in the demo — the only network with declines in this yearly comparison.

MS NOW was up 21% in primetime total viewers and 52% in the demo year-over-year, with total day gains of 33% and 83%. CNN posted the steepest annual growth: up 70% in primetime total viewers and 111% in the demo, and up 54% and 85% in total day.

The pattern is consistent across both comparisons: CNN and MS NOW are growing from election-cycle catalysts, while Fox News converts events into smaller margins of advantage. Whether these gains survive a non-election week is the number to watch next.
