Digital Video Ad Spending Rises, Inventory Trust Stagnates

Despite a significant surge in digital video ad spending, advertisers' trust in what is labeled as "premium" inventory has largely stagnated. This trend, observed in mid-2026, highlights a persistent disconnect between investment levels and confidence among media buyers and brand marketers globally.

The core issue is not a lack of budget but rather the perceived quality and transparency of available ad placements. Advertisers are committing more capital to video, driven by shifting audience behaviors towards streaming and short-form content. However, they continue to struggle with fundamental assurances such as viewability, brand safety, and the pervasive problem of invalid traffic (IVT). This directly impacts campaign effectiveness and the ability to demonstrate a clear return on investment.

The term "premium" itself has become increasingly diluted. What publishers or ad tech vendors classify as premium often fails to align with advertisers' expectations for high-quality content environments, minimal ad fraud, and verifiable human impressions. The programmatic supply chain, while offering efficiency and scale, frequently obscures the true path of an impression, making it challenging for buyers to audit inventory quality effectively.

This challenge is not new to digital advertising, but it is amplified in the video sector due to higher CPMs and the inherent complexity of video formats across diverse devices, including desktop, mobile, and connected TV (CTV). While direct deals can offer greater transparency and control, programmatic channels, particularly for CTV, continue to present significant hurdles.

Industry bodies and ad tech firms are actively developing solutions, such as supply path optimization (SPO) and enhanced verification tools. Yet, the adoption and standardization of these measures remain slow. As one media buyer noted, "Brands are still asking for basic verification metrics that should be table stakes by now." This indicates that fundamental trust issues are still unresolved, even as ad tech capabilities advance rapidly.

The growth of retail media networks (RMNs) introduces another layer of complexity. These platforms control their own inventory and first-party data, potentially offering more transparency within their specific ecosystems. However, this does not address the broader issues within the open web video market. Going forward, the industry will likely see sustained pressure for greater standardization in measurement and verification.

Advertisers will demand clearer, universally accepted definitions of "premium" and more robust tools to audit their video buys. Publishers that genuinely offer high-quality content and transparent selling practices are poised to benefit. Conversely, those who rely on opaque programmatic arbitrage will face increasing scrutiny and a potential shift in ad spend towards more verifiable channels. The push for attention metrics beyond simple viewability may also gain traction as a way to truly differentiate valuable inventory.
