Streaming Just Pulled Almost Level With Linear TV for America's Ad Dollars
TL;DR: Streaming captured 48.74% of US national TV ad spend in Q3 2026 against linear's 51.26%, yet delivered only 21.93% of impressions - meaning a streaming impression costs roughly 3.4 times a linear one, a premium advertisers can no longer ignore.
The crossover is almost here
New iSpot data for Q3 2026 (July to September) shows streaming took 48.74% of estimated US national TV ad spend, with linear on 51.26%. A year of steady drift has brought the two within a few points of each other, and the tipping point looks like a matter of quarters, not years.
Notably, the shift came less from streaming surging than from linear retreating: linear spend fell around 11% from Q2, while streaming stayed roughly flat. The crossover is being pulled forward by decline as much as by growth.
The number advertisers keep missing
Spend is only half the story. Streaming accounted for just 21.93% of impressions despite nearly half the budget, while linear delivered 78.07% of impressions. Do the maths and a streaming impression costs about 3.4 times a linear one.
That premium can be worth it - streaming offers addressability, measurement and incremental reach into cord-cutters. But it is not automatically efficient. Brands shifting budget on momentum alone risk paying three-times rates for audiences they could still reach more cheaply on linear.
What this means for businesses
The practical move is to stop treating streaming versus linear as an ideological choice and start treating it as a reach-and-frequency maths problem. Linear still delivers cheap, broad frequency; streaming delivers targeted, incremental reach. Most brands need both, in a deliberate ratio.
For smaller advertisers, the takeaway is sharper still: streaming's self-serve CTV tools finally make national-quality TV affordable, but only if you buy on outcomes, not on the novelty of being on streaming. Set a cost-per-incremental-reach target before you move a single pound.
The direction of travel is clear
None of this changes the trajectory. Linear's audience and budget are both eroding, and 2027 will likely be the year streaming takes the majority of US TV ad money. The brands that win the transition are the ones measuring incrementality now, while they still have a cheaper linear base to benchmark against.
Quick FAQ
Has streaming overtaken linear TV ad spend in the US?
Not quite. In Q3 2026, streaming reached 48.74% of US national TV ad spend versus linear's 51.26% (iSpot) - near-parity, with a crossover widely expected within the next few quarters.
Why is streaming more expensive per impression?
Streaming took nearly half the spend but only about 22% of impressions, so each impression costs roughly 3.4x a linear one. You pay for targeting, measurement and incremental reach rather than sheer volume.
Should advertisers move budget from linear to streaming?
Only against a clear reach-and-frequency plan. Linear still delivers cheap broad frequency; streaming delivers targeted incremental reach. Buy streaming on measured outcomes, not on novelty.
The headline everyone will share is 'streaming nearly overtook linear'. The number that actually matters is the 3.4x price gap. Streaming is powerful, but it is not free money - if you cannot measure the incremental reach you are buying, you are just paying a premium for a smaller audience. Buy on maths, not on momentum. - Daniel Nikolla, Founder of Merx Marketing
Streaming nearing half of US TV ad spend is a milestone - but the 3.4x cost-per-impression gap means budget should move on measured incrementality, not on momentum.
When you shift budget into streaming, are you tracking the incremental reach you are paying a premium for?
