43% of Media Buyers Lack Confidence in CTV Ad Supply Quality

43% of Media Buyers Distrust CTV Ad Supply — Including Direct Deals

The IAB's 2026 Digital Video report finds that 43% of media buyers have "somewhat to no confidence" in CTV (connected TV) ad supply quality. The stinging part: that distrust now extends to inventory bought through direct deals, not just the open programmatic exchange. The IAB names two causes — fraudsters injecting fake inventory into the supply chain, and genuine uncertainty about where legitimate inventory originated and where ads actually ran.

The right question for operators isn't whether CTV is growing (it is). It's who gets paid inside that growth.

What actually shifts

When buyers distrust supply, verification vendors collect a toll. DoubleVerify and Integral Ad Science (IAS) — third-party ad verification platforms — capture budget that would otherwise buy actual ads. This is a quiet transfer from working media to measurement, and it's already showing up in live RFP language as verification riders bolted onto deals.

The second shift is a repricing of inventory. Premium publishers with clean, documented supply — NBCU, Disney — gain pricing power because their provenance is legible. Long-tail free streaming aggregators like Tubi, Pluto, and Xumo absorb the scrutiny because their supply chains are harder to audit.

The direct-deal break matters most

CTV distrust in the open exchange is years old. Distrust of direct-sold premium inventory is new, and it's the consequential part. "Buy direct, stay clean" was the entire safety story buyers told themselves. Once that assumption collapses, verification tags migrate onto programmatic guaranteed and premium deals — meaning the toll gets collected across the whole category, not just the sketchy corners. Any DSP (demand-side ad-buying platform) without real CTV supply-chain transparency tooling will start losing mandates without being told why.

Publishers face a different cost: building content-level and audience-provenance documentation is real engineering spend with no immediate revenue attached — until it becomes what wins the RFP. It's defensive capital expenditure, and waiting makes it more expensive.

A note on the survey

54% of buyers are confident, and CTV budgets have grown every year since buyers started complaining about supply quality in 2019. Stated distrust does not reliably predict where dollars go — advertisers chase audiences, and audiences are on CTV. Total spend likely keeps climbing. What changes is the internal mix: more dollars to verification, more pricing power to documented publishers, less margin for opaque aggregators.

Our call: On its Q3 2026 earnings call, at least one of DoubleVerify or IAS will explicitly cite CTV verification demand as a growth driver and report double-digit year-over-year growth in CTV-related revenue — because the demand mechanism is already written into live RFPs, and a fresh industry-wide trust scare pushes that revenue line up, not down.

The IAB's 2026 Digital Video report says 43% of media buyers have "somewhat to no confidence" in CTV ad supply quality — and here's the part that stings, that distrust now includes inventory bought through direct deals. Chris Bruderle at the IAB names two culprits: fraudsters shoving fake inventory into the pipes, and plain uncertainty about where legitimate inventory actually came from and where the ad ran. For an ad-tech operator, the question isn't "is CTV growing?" It is. The question is who gets paid inside that growth, and who quietly gets squeezed.

This is a Type 2 situation for most operators — reversible, adjustable quarter to quarter. Nobody has to bet the company on it. What's actually being decided is where the next dollar of CTV budget flows: into working media, or into the verification and transparency layer wrapped around it. The forcing function is the current RFP cycle, where these riders get written in.

The Market Analyst — Follow the money, not the mood. When half the buy side distrusts the supply, verification vendors collect a toll. DoubleVerify, IAS, and Comscore get budget that used to buy actual ads — a quiet transfer from media to measurement, happening in live RFPs. The second move is a repricing: premium publishers with clean, documented inventory — NBCU, Disney — gain pricing power, while long-tail free streaming aggregators (Tubi, Pluto, Xumo) wear the scrutiny. Plain version: when buyers get nervous, the referees get rich and the trusted brands charge more. Clean supply stops being assumed and becomes a paid-for premium.

The Skeptic — 54% of buyers ARE confident. This is a sentiment survey, not a spending survey. Buyers have griped about CTV supply quality since 2019, and CTV budgets have grown every single year regardless. The load-bearing assumption is that stated confidence predicts where dollars go. It doesn't, reliably. Advertisers chase audiences, and audiences are on the couch. Plain version: people say they're worried and then spend the money anyway. And note who's holding the megaphone — the IAB is a trade body, and a trust-gap report is also a pitch for self-regulatory frameworks its members would build and sell. Watch the budget lines, not the survey.

The Operator — Trafficking desks feel this on Tuesday morning. 43% distrust means RFPs arrive with extra verification riders bolted on, and the direct-deal workflow is where it breaks first. Buyers assumed direct equals clean; this report kills that assumption. So now programmatic guaranteed deals — the "premium" ones — start requiring third-party tags too, which adds latency, cost, and one more thing to reconcile when the numbers don't match. Plain version: even the "safe" buys now need a chaperone. Supply-path conversations accelerate, and any DSP without real CTV supply-chain transparency tooling starts losing mandates without ever being told why.

The CFO — Someone pays for all this verification, and it isn't the fraudsters. Every rider is a tax on the media dollar — the working-media portion of a CTV buy shrinks while the invoice stays flat. For a publisher, the cost is different: building content-level and audience-provenance documentation is real engineering spend with no new revenue attached, until it becomes the thing that wins the RFP. That's the payback question. Clean-supply investment doesn't lift CPMs on day one; it prevents the slow bleed of losing to the publisher who documented better. Defensive capex, and the ones who wait pay more later.

Where they disagree

Two sharp splits. First, does distrust actually move budget? The Skeptic says no — twelve years of complaints, twelve years of growth, spend follows audiences. The Market Analyst and Operator say the mechanism has changed: distrust doesn't shrink the CTV pie, it reroutes dollars within it, from working media to verification and from opaque aggregators to documented premium. Both can be right at once — total spend keeps climbing while the mix quietly reshuffles.

Second, is this a real structural crisis or a trade-body moment? The Skeptic flags that the IAB benefits from the alarm it's ringing. The Operator counters that the direct-deal trust break is concrete and already showing up in RFP language, regardless of who published the number.

What it hinges on

The whole thing turns on one fact: does the loss of trust in direct deals stick? CTV distrust in the open exchange is old news. Distrust of direct-sold premium inventory is new, and it's the part that reprices the market — because "buy direct, stay clean" was the entire safety story buyers told themselves. If that assumption is dead, verification tags migrate onto premium buys and the toll gets collected across the whole category, not just the sketchy corners.

The council leans one way: total CTV spend keeps growing, but the money reshuffles toward the referees and the documented publishers. That's the near-certain part. The bold part — how fast — is where I'll plant a flag.

Prediction: On its Q3 2026 earnings call, at least one of DoubleVerify or Integral Ad Science will explicitly cite CTV verification demand as a growth driver and report double-digit year-over-year growth in CTV-related revenue.

Confidence: Medium — the demand mechanism is already in live RFPs, and both firms narrate CTV every quarter.

Why: The IAB report says distrust now reaches direct deals, and the Operator lens shows that translates directly into third-party verification tags on programmatic guaranteed and premium buys — the exact revenue line DoubleVerify and IAS sell. Both companies have leaned on CTV as their growth story for several quarters, so a fresh, industry-wide trust scare pushes that line up, not down. The opposite outcome — flat or declining CTV verification revenue while a major report tells every buyer to demand more of it — would run against both the incentive and the buyers' stated behavior, which is why it's the less likely read.

Revisit by 2026-11-15: We're right if DoubleVerify or IAS names CTV verification demand as a driver and posts double-digit CTV revenue growth on the Q3 call. We're wrong if both stay silent on CTV as a driver or report single-digit/declining CTV growth.

One caveat worth holding: the Skeptic's point that spend follows audiences means this prediction is about the toll growing, not about anyone's core budget shrinking. Those are different bets, and only the toll is a safe one.
