Viant Technology today launched Publisher Solutions, a free tool set that lets publishers see - for the first time - how their supply actually appears inside a demand-side platform, including which bid signals are present, where coverage is breaking down, and how the platform values their inventory.

Viant Technology (NASDAQ: DSP) today announced the launch of its expanded Publisher Solutions, a centralized set of tools that gives publishers direct visibility into how the Irvine, California-based DSP evaluates and bids on their programmatic and CTV inventory. The company describes it as a free portal - with no cost to publisher partners - that exposes signal quality, identity coverage, supply path efficiency, and content classification data in a single dashboard.

The announcement, dated June 11, 2026, arrives more than two decades into a programmatic ecosystem in which publishers have routinely submitted inventory into DSPs without any view into what happens on the buy side. Tim Vanderhook, CEO of Viant, put the problem plainly in a LinkedIn post published on the day of the launch: "Publishers have been sending inventory into DSPs for two decades without ever seeing what happens on the other side. We think that's a problem worth fixing."

What Publisher Solutions actually includes

The centerpiece of the launch is SupplyIQ, a publisher-specific reporting dashboard that consolidates key performance data across four signal categories: Direct Access, Household ID (HHID), and IRIS_ID. These three inputs, according to Viant, form a unified framework that directly influences how the platform values inventory, allocates spend, and optimizes campaign performance.

SupplyIQ is not simply a reporting layer. According to Viant, the tool ensures the platform only bids on inventory that meets defined signal quality thresholds required to drive advertiser outcomes. Publishers who fall short of those thresholds can use SupplyIQ's reporting layer to understand where the gap is and what specific improvements would directly affect their monetization.

That last point matters. The dashboard creates an explicit link between signal quality and revenue. Better signals mean more of Viant's bidder is engaged on a publisher's inventory. Gaps in signals mean the bidder deprioritizes that supply - and until today, publishers had no way to know that was happening.

Direct Access is Viant's Supply Path Optimization framework, designed to connect advertisers to CTV and digital inventory through the most direct and cost-efficient routes available. According to Viant, 85% of CTV spend on the platform is currently transacted through Direct Access. The company says it charges publishers nothing for participation, a contrast with competing SPO programs that take a percentage of advertiser spend. By eliminating intermediary hops, Viant says Direct Access reduces auction noise and ensures a greater share of every advertiser dollar goes toward working media rather than intermediary fees.

Household ID (HHID) is Viant's publisher-side identity integration. Publishers can sync their first-party data into Viant's deterministic identity framework, which the company says covers 95% of U.S. adults aged 18 and above. The result is increased addressability and measurement capability: advertisers gain more accurate audience targeting, cross-device frequency management, and improved attribution. This identity infrastructure has been built incrementally - a January 2025 partnership with TransUnion expanded Household ID match rates to that 95% threshold, creating a cookieless identity layer that persists across CTV environments where traditional cookies have never worked.

IRIS_ID is Viant's content identification and targeting solution, inherited from its acquisition of IRIS.TV in November 2024. Publishers can map their video content to standardized IRIS Content IDs, which unlocks monetization strategies based on content-level signals. Advertisers can then target and measure campaigns at the content level - by genre, show, scene, or pod - improving contextual alignment without relying on user-level tracking. IRIS_ID's presence in the CTV bidstream more than tripled within one year of that acquisition, according to Viant's Q3 2025 earnings report.

The business logic behind opening the books

Viant is a buy-side-only platform. It does not sell inventory. That structural fact is central to understanding why the company says it can offer this level of transparency without a conflict of interest: there is no sell-side margin to protect. "Viant is buy-side only," Vanderhook wrote in his launch post. "This is about giving our partners the same view we have."

The economic reasoning runs in both directions. Publishers who understand where their signals are weak can fix those gaps. Fixed gaps mean higher-quality supply. Higher-quality supply means Viant's bidder engages more actively, which means more revenue flows to those publishers. According to Viant, this incentive structure continuously raises the quality and transparency of supply across the open internet.

"Today's programmatic ecosystem requires deeper alignment between premium supply and brand advertisers," said Tim Vanderhook, CEO of Viant Technology. "With Viant Publisher Solutions, we are creating a more transparent and efficient marketplace, giving publishers control and insight into their inventory while enabling advertisers to access premium, signal-rich supply that drives real, measurable outcomes."

The transparency argument is not unique to Viant. The programmatic industry has been wrestling with signal quality, supply path complexity, and working media ratios for years. PPC Land's coverage of publisher bid throttling strategies in 2025 documented how publishers were already deploying their own defensive mechanisms against inefficient demand - a sign that the information asymmetry between buyers and sellers was generating friction on both sides. IAB Spain's SSP guide, covered by PPC Land in April 2026, cited ANA 2025 benchmark data showing that only 41 cents of every programmatic dollar reaches working media, the rest consumed by intermediary fees and technical overhead.

Viant's response - described internally as opening the books - is to collapse that information gap by giving publishers access to the same bidder data that Viant's own teams use.

Publisher adoption and named partnerships

According to Viant, Publisher Solutions have already been broadly adopted across the programmatic ecosystem, representing some of the most-watched streaming content in the world. The company says expansion will continue throughout 2026, though it has not published specific adoption figures.

Tubi is named in the launch announcement as a direct partner. "As a publisher, creating more direct relationships with DSPs is increasingly important to maximize both transparency and monetization," said Vijay Rao, Senior Vice President of Partnerships at Tubi. "Viant's Direct Access framework gives us a way to collaborate more closely, improve signal quality, and unlock incremental revenue opportunities without additional platform fees."

Tubi's involvement is notable. It is among the most prominent publishers in Viant's Direct Access program, alongside Disney+, Paramount+, NBCUniversal, and Samsung. In Q3 2025, CTV accounted for 46% of total advertiser spend on Viant's platform - an all-time high - and nearly half of that volume flowed through Direct Access.

The Molson Coors Beverage Company is also cited in the launch materials. Brad Feinberg, Vice President of Media and Marketing Operations at Molson Coors, said: "In CTV, transparency and innovation are not just nice to have; they are the foundation of effective advertising. Viant delivers on both, and their Household ID and identity framework gives Molson Coors the future-proofed foundation to power our marketing effectiveness and digital transformation ambitions in 2026 and beyond."

Molson Coors became one of Viant's more visible brand partnerships when it was announced alongside Q3 2025 earnings results. Feinberg's statement ties the Publisher Solutions launch directly to advertiser concerns - a signal that the demand side has a stake in publisher signal quality, not just publishers themselves.

How SupplyIQ changes the publisher workflow

The practical mechanics of SupplyIQ deserve attention. Before this tool existed, a publisher submitting bid requests into Viant's system had no visibility into which signals were being passed correctly, which were missing, and which gaps were causing the bidder to deprioritize their supply. The only indicator was revenue - and low revenue without diagnostic data offers no clear path to improvement.

SupplyIQ changes that workflow. According to Viant, the dashboard shows publishers which signals are present on their bid requests, where coverage is breaking down, and how Viant scores the inventory. Publishers can see their Direct Access integration status, their Household ID coverage, and their IRIS_ID implementation - all in one place.

The approach shares some conceptual DNA with the Prebid community's ongoing work on transaction IDs and signal transparency, covered by PPC Land in August 2025, where publishers fought to maintain visibility into how their supply traveled through the auction stack. The distinction is that SupplyIQ operates entirely on the demand side - it is a DSP revealing its own scoring criteria rather than a supply-side tool.

The broader context: Viant's infrastructure build

Today's announcement does not sit in isolation. Over roughly 18 months, Viant has assembled what it calls an intelligence layer through a series of acquisitions and partnerships, each adding a distinct data input to the platform.

In November 2024, Viant acquired IRIS.TV, gaining the IRIS_ID content classification system. In March 2025, it completed the acquisition of Lockr, a first-party data collaboration platform designed to reduce friction in identity matching for publishers. In August 2025, the company integrated with Wurl for scene-level CTV targeting, becoming the first DSP to deliver contextual intelligence at the scene level. In April 2026, Viant announced a $40 million acquisition of TVision Insights, closing in May 2026 and adding second-by-second attention measurement to the stack.

Publisher Solutions and SupplyIQ represent the publisher-facing interface to much of that infrastructure. The signals that SupplyIQ exposes - Direct Access connectivity, Household ID coverage, IRIS_ID implementation - are precisely the inputs Viant uses internally to score inventory and make bidding decisions. Opening that scoring logic to publishers completes a loop that previously existed only on the buy side.

The LG Ad Solutions integration announced in July 2025 demonstrated the same principle at the device level: direct integration across LG's 45 million connected devices in the United States enabled by Viant's Household ID and IRIS_ID infrastructure. SupplyIQ gives any publisher the diagnostic tools to understand whether their supply is set up to participate in that kind of direct integration.

Why this matters for media buyers

From an advertiser's perspective, publisher signal quality is not abstract. It determines whether campaigns can be targeted accurately, whether frequency can be controlled across devices, whether contextual alignment is achievable, and whether attribution is measurable. Viant's framing - that better publisher signals mean more of every dollar goes to working media - maps directly to the working media ratio problem the industry has struggled to solve.

The iHeartMedia audio integration from December 2025 illustrated how Viant operationalizes publisher integrations once signal infrastructure is in place: inventory that previously required manual insertion orders became programmatically accessible. The same logic applies here. Publishers who improve their SupplyIQ scores - by connecting through Direct Access, improving Household ID coverage, and implementing IRIS_ID - become more accessible to Viant's automated buying system without any additional intermediary layer.

According to Viant, the platform is exclusively buy-side. That position matters for the marketing community because a buy-side-only DSP's incentive for improving publisher signal quality is aligned with advertiser outcomes rather than with maximizing its own supply margin. Richie Hyden, SVP of Publisher Solutions at Viant, who led the iHeartMedia audio integration, is identified in the launch documentation as the Viant executive responsible for publisher relationships.

Timeline

Summary

Who: Viant Technology Inc. (NASDAQ: DSP), an exclusively buy-side, AI-powered programmatic advertising platform headquartered in Irvine, California, alongside publisher partners including Tubi and brand partner Molson Coors Beverage Company.

What: Viant today launched enhanced Publisher Solutions, a free centralized tool set featuring SupplyIQ - a publisher-specific dashboard that exposes signal quality, Direct Access integration status, Household ID coverage, and IRIS_ID implementation directly to publishers. The tools are available at no cost, unlike competing solutions that charge publishers a share of advertiser spend. 85% of CTV spend on the Viant platform currently flows through Direct Access.

When: The announcement was made on June 11, 2026. Publisher Solutions are available immediately to Viant's publisher partners. The company says broad adoption has already occurred, with expansion continuing throughout 2026.

Where: Viant operates its programmatic platform across the United States, with the Publisher Solutions portal accessible at viantinc.com/solutions/publisher. The tool is relevant globally for any publisher submitting inventory into the Viant DSP.

Why: Publishers have historically submitted bid requests into DSPs without visibility into how those requests are evaluated, which signals are missing, or why demand may be weaker than expected. SupplyIQ closes that information gap by giving publishers access to the same scoring data Viant uses internally. The business rationale is circular: publishers who fix signal gaps generate more revenue; Viant's bidder engages more actively on higher-quality supply; advertisers benefit from more addressable, measurable inventory. The tool is free because, according to Viant, transparency does not cost anything - and the company has no sell-side revenue to protect.
