FAST viewing hours growth hits 43% despite platform data hoarding

The disconnect between surging viewership and falling CPMs suggests a structural failure in the FAST advertising market. While platforms like Tubi and Pluto TV are tracked by Nielsen, smaller channels remain unverified, leading agencies to discount inventory they cannot independently audit. This lack of transparency gives distribution platforms an unfair advantage in content negotiations but ultimately suppresses the entire category's valuation. If the industry fails to adopt device-level verification, the shift from cable to streaming will continue to be marred by inefficient pricing. Watch for whether major platforms grant third-party measurement firms access to raw device-level data to stabilize ad economics.

As brands seek better performance, script lift measurement is increasingly being used to justify CTV budgets despite ongoing data transparency hurdles. To address these challenges, Teads CTV Ensemble launch aims to improve lower-funnel performance for streaming advertisers, though ACR data measurement blind spots continue to complicate verification efforts. Meanwhile, CTV advertising market power is shifting toward buyers as inventory volumes continue to surge, even as advertisers plan live sports investment despite these measurement hurdles, a trend highlighted by recent IAB report findings regarding inventory confidence, which is further complicated by CTV ad inventory mislabelling that costs advertisers billions, while IAB Tech Lab bundle IDs are being redefined to combat rising fraud. Recent HP TV+ Magnite partnership further highlights how platforms are attempting to integrate new data sources to improve FAST advertising, while programmatic data enrichment faces 32% inaccuracy rates as privacy rules restrict behavioral targeting. To improve audience signal transparency, new supply-side platforms are entering the market to help publishers navigate these data challenges.
