Social video is no longer a support line item. It has become the biggest bucket in US digital video spend, and advertisers are chasing audiences into algorithm-driven feeds.
The category is beating CTV
The IAB’s 2026 forecast puts US social video at $31.9 billion, up 13% year over year. That edges out connected TV at $29.3 billion and online video at $20.7 billion. The comparison depends on the IAB counting YouTube inside social video, but the direction is clear: feed-based video has become the default way many brands buy attention.
Australia shows the same pattern. Social video grew 29.5% to A$2.4 billion in the 2026 financial year and now takes 41% of all video spend.
What buyers actually control
Most social video inventory never leaves the platform. You upload a native asset in Meta Ads Manager, TikTok Ads Manager or Google Ads, choose an objective, set targeting and budget, and the platform’s auction decides delivery. There is no separate Instagram ad account; Instagram placements sit inside the Meta auction.
Buyers can use auction pricing or reservation buys. TikTok’s premium TopView and TopFeed slots were combined into TopReach in March 2026, with TikTok claiming 59% incremental reach. Meta’s ThruPlay optimization works in both buying modes.
Measurement is the real problem
A view is not the same thing from one platform to the next. Meta counts a ThruPlay as a play to completion for clips under 15 seconds, or at least 15 seconds for longer videos, while its engage-through attribution threshold dropped from 10 seconds to 5 seconds on March 3, 2026. YouTube credits engaged views at 10 seconds for skippable in-stream ads and 5 seconds for in-feed and Shorts, and from August 24, 2026 counts a public view from the first frame.
The same 20-second video can log a view on one platform, fail to log one on another and earn conversion credit on a third. That makes cross-channel cost-per-view comparisons misleading unless teams rebuild benchmarks per placement.
This is not a new problem. Facebook’s silent autoplay format set the template back in 2014, and The Wall Street Journal reported in 2016 that the platform had overestimated average video viewing time by 60% to 80% for two years. Facebook later agreed to a $40 million settlement with advertisers while contesting the claims.
- Set one platform-native KPI per placement instead of importing a single CPV benchmark.
- Treat platform-reported views as directional and add incrementality or lift tests where possible.
- Design vertical 9:16 creative first, but check placement specs before repurposing.
- Watch the EU push to disable Meta autoplay by default, which could reshape feed video reach.
Why it matters now
The format shift is accelerating. Sensor Tower estimated Reels absorbed 51% of Instagram user time and more than half of app ad placements in Q2 2026. The first MRC brand safety accreditation for short-form inventory went to YouTube Shorts only on June 3, 2026, showing how long independent oversight has lagged.
For performance marketers, social video offers scale, targeting and low production costs, but it also means accepting measurement controlled by the same companies selling the inventory. Build your own controls around the platform numbers, and treat definitions as part of the strategy.
