Something is shifting inside the competitive intelligence layer of Amazon and Walmart advertising, and the people who build tools for marketplace sellers are paying close attention. According to three sources close to the matter — two at competing ad tech platforms and one at a large multichannel agency — Pacvue has allegedly been in advanced discussions with Walmart Connect to secure a data-sharing arrangement that would give its platform earlier and deeper access to Walmart’s sponsored product performance signals than any third-party tool currently receives.
The deal, which remains unconfirmed by either Pacvue or Walmart, is reportedly structured around a co-development framework that would allow Pacvue’s optimization engine to ingest Walmart Connect campaign data at a latency advantage of several hours compared to standard API access. For sellers running high-velocity SKUs on Walmart Marketplace — particularly in consumables, home goods, and electronics — even a three-to-four-hour data edge can meaningfully shift bid decisions and ACOS outcomes.
“If this is real, it fundamentally changes who wins Walmart marketplace PPC,” said one agency director at a Chicago-based Amazon and Walmart management shop who asked not to be identified. “Everyone is scrambling to figure out what Pacvue actually has versus what they’re implying they have.”
What Is Pacvue Allegedly Gaining From This Arrangement?
Sources describe the alleged arrangement as something beyond a standard API partnership. Competing platforms — including Perpetua, Teikametrics, and Intentwise — currently access Walmart Connect data through the same normalized API endpoints available to any approved advertising partner. If Pacvue has indeed negotiated a preferential data tier, it would represent a structural moat that rivals couldn’t close simply by improving their own algorithms.
One source at a competing ad tech vendor described it bluntly:
“The Amazon side of our business is mature. Everyone is fighting over the same signals. Walmart is where the next three years of growth live, and if one platform locks up preferential data access, the rest of us are just running slower with better intentions.”
Pacvue CEO Melissa Burdick, who has publicly positioned the platform as the enterprise standard for omnichannel retail media, has not commented on the specific allegations. However, in a recent industry appearance, she reportedly referenced Walmart Connect as “a strategic growth pillar, not a secondary channel” — language that several competitors found pointed in retrospect.
Why Are Teikametrics and Perpetua Reportedly Alarmed?
The timing of the alleged deal matters. Walmart Marketplace seller growth has accelerated meaningfully in 2026, with sources at Jungle Scout and Helium 10 both citing sharp upticks in Walmart-specific keyword research queries on their platforms over the last two quarters. More enterprise brands are shifting meaningful ad budgets from Amazon Sponsored Products to Walmart Connect, particularly as Amazon’s average CPC in high-competition categories has reportedly climbed past $2.80 in categories like supplements and kitchen appliances.
For Teikametrics, which has built much of its recent positioning around AI-driven bid optimization that works equally well across Amazon and Walmart, a Pacvue data advantage at the Walmart layer would undercut one of its core competitive arguments. Teikametrics CEO Alasdair McLean-Foreman has not publicly addressed the rumor, but sources at a Boston-based multichannel agency that works with Teikametrics said there has been “noticeable internal urgency” around Walmart data strategy in recent weeks.
Perpetua, which was acquired by Jungle Scout’s parent company in 2023 and has leaned heavily into enterprise Amazon PPC, is also allegedly feeling pressure. According to one source familiar with Perpetua’s account team conversations, several mid-market clients have directly asked whether the platform has any preferential Walmart data access — suggesting the Pacvue rumor has already traveled from agency hallways to merchant Slack channels.
Is Walmart Connect Actually Capable of Structuring a Preferential Data Deal?
This is where the story gets complicated. Walmart Connect has been aggressively professionalizing its advertising infrastructure since bringing in former Amazon Ads executive Rich Lehrfeld as SVP of Walmart Connect in 2021. The organization has since built out a proper API partner ecosystem, launched closed-loop attribution tools, and begun courting enterprise brands with dedicated managed service teams.
But sources who work directly with Walmart Connect’s partner engineering team say the platform’s API architecture, while improved, still lacks the maturity to reliably deliver the kind of structured preferential data tier being described in the Pacvue rumor. “It’s not impossible,” said one source, “but Walmart’s ad tech infrastructure is still catching up to where Amazon was in 2019. A real latency-advantage data tier would require significant custom engineering on their side.”
“Walmart wants a dominant third-party tool ecosystem, just like Amazon has. They have every incentive to make this kind of deal happen — the question is whether the pipes are actually there yet.”
That ambiguity has done nothing to quiet the speculation. If anything, the uncertainty about what is technically feasible has made the rumor more durable.
How Are Amazon-Focused Agencies Reacting to the Alleged Shift?
Inside large multichannel agencies — particularly those managing eight-figure Amazon ad budgets who have been building Walmart practices in parallel — the alleged Pacvue deal is reportedly accelerating vendor review cycles that might otherwise have happened organically over the next twelve months.
- At least two agencies with over $50M in combined Walmart ad spend under management have reportedly initiated informal RFP processes specifically to benchmark Pacvue’s Walmart performance against Teikametrics and Perpetua.
- One agency operating out of New York’s DTC corridor has allegedly paused a planned expansion of its Perpetua contract pending clarity on Walmart data access across all major platforms.
- Several Seller Central power users in private Facebook groups and Discord communities dedicated to eight-figure Amazon brands have begun circulating screenshots of Pacvue sales decks that reference “exclusive Walmart Connect partner” language — though the authenticity of the decks has not been verified.
- At least one senior media buyer at a Midwest-based Amazon agency told colleagues at a recent industry dinner that they had directly asked their Pacvue account manager about the arrangement and received what they described as “a non-denial denial.”
What Does This Mean for Sellers Actually Running Walmart Ads?
For the average Walmart Marketplace seller running Walmart Connect campaigns through any of the major third-party bid management tools, the immediate practical implication is limited. The alleged data advantage, if real, would primarily benefit enterprise accounts running high-volume, high-velocity campaigns where marginal bid optimization improvements compound meaningfully over time.
But the strategic signal is significant. If Pacvue does have a structural data edge at Walmart — even a temporary one — it could accelerate the consolidation of enterprise ad management spend onto a single platform in a way that hasn’t happened on the Amazon side, where Teikametrics, Perpetua, Intentwise, Scale Insights, and others continue to compete vigorously.
Brad Moss, a well-known Amazon PPC consultant and founder of a boutique seller advisory practice, reportedly told clients in a recent newsletter that they should “pressure every tool vendor you work with for a straight answer on Walmart data access before your next contract renewal.” Moss could not be reached to confirm the specific language.
“The Walmart ad market is at a similar inflection point Amazon was around 2018 — before the big agencies locked in their tool preferences and essentially froze out newer entrants for years. Whoever owns enterprise Walmart PPC infrastructure in the next eighteen months probably owns it for a decade.”
Will Amazon Sellers Who Ignored Walmart Finally Be Forced to Pay Attention?
The broader irony in this story is that the rumored Pacvue deal — real or exaggerated — is functioning as a kind of involuntary marketing event for Walmart Marketplace as an advertising channel. Every agency conversation about what Pacvue may or may not have is also a conversation about Walmart’s maturation as a retail media network, its growing CPM and CPC inventory, and the risk of being late to a platform that is now reportedly generating over $4.5 billion in annual advertising revenue.
For Amazon sellers who have treated Walmart as a secondary channel requiring minimal dedicated strategy, the message filtering through the vendor community is pointed: Walmart Connect is no longer a place where last-click attribution and manual bid management are sufficient. Whether or not Pacvue has secured preferential data access, the competitive pressure to professionalize Walmart ad operations is intensifying regardless.
Pacvue did not respond to a request for comment before publication. Walmart Connect declined to confirm or deny the existence of any preferential data-sharing arrangement with third-party advertising platforms. Teikametrics and Perpetua also did not respond to requests for comment.
Ecommerce Times will continue to report on developments in the Walmart advertising partner ecosystem as additional information becomes available.
