Do you trust cable news coverage of political campaigns to be fair and accurate?

Average political ad spending on the big three national cable news networks rose 47% in the 30 days before the midterms, according to iSpot estimates. Fox News Channel led all networks with $90.1 million in ad spend over the period.

Why it matters

The surge reflects campaigns and advertisers concentrating heavy budgets on cable news audiences in the final weeks before voters went to the polls. Shifts in where political money flows shape which networks gain advertising revenue during election cycles.

Fox News Channel aired 21,811 ads reaching 27.3 billion impressions, MS NOW aired 20,706 ads reaching 8.7 billion impressions, and CNN aired 25,610 ads reaching 7.7 billion impressions. These are iSpot estimates, and the source does not break out how much of the spending came from political advertisers.

Market Landscape

Election-season spending has long pushed heavy ad budgets toward the big three cable news networks in the final weeks before voting. This 2026 surge fits that established cycle, with the gains spread across Fox News, MS NOW, and CNN.

Heavier political ad loads on cable news can mean more commercial breaks for viewers in the weeks before an election. The spending shift also signals where campaign budgets are concentrated, which affects which networks and programs gain advertising revenue.

The takeaway

Election-season ad spikes concentrate on a few cable networks, so audiences should expect heavier commercial loads on those channels in late cycles. Tracking such spending helps explain how campaigns allocate money across media.
