Helium 10’s Rumored Data-Sharing Deal With Amazon Is Alarming Sellers

Something unusual is circulating in the Amazon seller community this week, and the volume is getting hard to ignore. Multiple agency operators and high-volume FBA sellers have told Ecommerce Times that Helium 10 — the dominant Amazon research and listing optimization platform used by an estimated 2 million sellers — is allegedly in advanced talks with Amazon’s Selling Partner Services division about a data-licensing arrangement that, if finalized, would give Amazon access to anonymized behavioral data from Helium 10’s user base.

Sources close to the matter say the discussions have been ongoing since at least Q1 2026 and are described internally as a “strategic intelligence partnership.” The alleged arrangement would reportedly allow Amazon to ingest aggregated search behavior, keyword intent signals, and product opportunity data generated by sellers using Helium 10 tools like Cerebro, Black Box, and Magnet — ostensibly to improve Amazon’s own search ranking systems and demand forecasting models.

Helium 10 has not confirmed or denied the reports. Amazon declined to comment.

What Exactly Is Being Shared — And With Whom?

The specifics, according to two people with direct knowledge of the alleged negotiations, are still being debated internally. One source, a former Helium 10 enterprise account manager who departed the company in early 2026, described the scope as “broader than most sellers would be comfortable with.”

“The concern isn’t that Amazon gets anonymized data — it’s that Amazon is effectively buying a map of where every serious seller is hunting for white space. That’s not anonymized in any meaningful way at scale.” — former Helium 10 enterprise account manager, speaking on condition of anonymity

Unconfirmed reports suggest the deal could be structured as a revenue-share model rather than a flat licensing fee, with Amazon contributing engineering resources to help Helium 10 build out its AI-driven listing tools in exchange for data access rights. This framing reportedly makes the arrangement easier to ratify internally at Helium 10’s parent company, Assembly, which acquired Helium 10 in 2021 and has since folded in several other seller tools including Sellbrite and Web Retailer.

Assembly CEO Rahul Gupta has not commented publicly. But sources at two competing platforms say his team has been unusually quiet at industry events over the past six weeks — a silence that has started to draw attention in its own right.

Why Are Sellers So Worried About This?

The seller anxiety here is rooted in a well-documented pattern. Amazon has faced years of scrutiny — including a 2020 Wall Street Journal investigation and subsequent Congressional hearings — over its alleged use of third-party seller data to inform its own private label decisions. While Amazon disputed those claims, the specter has never fully dissipated from the seller community’s collective consciousness.

For FBA operators running seven- and eight-figure businesses, the prospect of their competitive research flowing upstream to Amazon is existential. The fear is specific:

• Amazon could identify underserved niches that sellers are actively researching and move to launch competing products or source directly from those suppliers
• Keyword bidding patterns could reveal which product categories sellers are expanding into, giving Amazon Ads the ability to inflate CPCs in those verticals just as sellers ramp spend
• Buy Box algorithm inputs could theoretically be tuned to deprioritize sellers whose research behavior signals thin margins or fragile supply chains
• Competitor sellers — particularly large domestic and Chinese aggregators already inside Amazon’s Brand Registry programs — could benefit indirectly if Amazon’s A9/A10 algorithm absorbs and redistributes that intent data

“These aren’t paranoid hypotheticals at this point,” said Liran Hirschkorn, founder of Incrementum Digital, a full-service Amazon agency managing over $40 million in annual ad spend. “We’ve seen enough from Amazon over the years to know that data flows upward and doesn’t come back. If this is real, our clients need to know yesterday.”

“If Helium 10 is feeding Amazon’s machine, you’ve basically handed your entire research playbook to the referee. That’s not a partnership — that’s a conflict of interest.” — Liran Hirschkorn, founder, Incrementum Digital

Is Helium 10 the Only Tool Under Scrutiny?

Sources say Helium 10 is not the only third-party platform that has allegedly been approached about some form of data collaboration with Amazon. Jungle Scout — Helium 10’s closest competitor, with an estimated 700,000 active users — is reportedly not part of the current discussions, according to two people familiar with the matter. A spokesperson for Jungle Scout did not respond to a request for comment by press time.

Perpetua, the Amazon PPC automation platform owned by Epsilon, and Pacvue, which handles programmatic ad management for large brand advertisers on Amazon DSP, are also said to have received informal outreach from Amazon’s advertising partnerships team — though the framing there is reportedly narrower, focused on ad attribution modeling rather than product research data. Pacvue declined to comment.

The breadth of the alleged outreach is itself telling. It suggests Amazon may be attempting to assemble a mosaic of third-party behavioral data across the full seller funnel — from product discovery through listing optimization through paid amplification — in ways that would give its internal teams a structurally superior view of the competitive landscape.

What Does This Mean for Seller Trust in Third-Party Tools?

The fallout, even at the rumor stage, has been swift in certain corners of the seller community. On the Amazon Seller Central subreddit and several private Slack groups for FBA aggregators, threads discussing the alleged deal surfaced as early as May 19 and have accumulated thousands of comments. Sentiment is running overwhelmingly negative.

Several agency operators told Ecommerce Times they are already auditing which tools their teams use and whether those tools’ terms of service grant data-sharing rights to third parties — including platform partners. The concern is that most sellers have never read those clauses carefully.

• Helium 10’s current Terms of Service, last updated in November 2025, includes language allowing it to share “de-identified, aggregated data with third-party service providers and business partners” — a clause broad enough to arguably cover the alleged Amazon arrangement
• Jungle Scout’s ToS contains similar language, as does DataHawk and SmartScout
• Several sellers on Reddit noted that SmartScout, the newer entrant in Amazon market intelligence, does not currently include equivalent language — a distinction SmartScout CEO Scott Needham quickly amplified on LinkedIn on May 20

“We’ve always taken an explicit position that our data belongs to sellers, not platforms. This week, that position just became a product feature.” — Scott Needham, CEO, SmartScout, via LinkedIn post, May 20, 2026

Whether or not the Helium 10 deal is real, Needham’s framing landed well. SmartScout reportedly saw its highest single-day free trial signup volume on May 20 since the platform’s launch.

Could Amazon Regulators in the EU or US Step In?

The alleged arrangement is also drawing the attention of policy observers. The European Commission’s Digital Markets Act, now in full enforcement mode, includes explicit provisions around data leveraging by designated gatekeepers — and Amazon holds gatekeeper status under the DMA. If the Helium 10 data-sharing structure is confirmed, EU regulators could argue it constitutes a prohibited form of data self-preferencing, even if the data is technically sourced from a third party.

In the US, the FTC’s ongoing Amazon investigation — which has focused heavily on the company’s treatment of third-party sellers — would likely take interest as well, sources say. “The FTC has been building a record on exactly this kind of conduct,” said one Washington-based ecommerce policy consultant who works with marketplace operators. “If this deal gets inked and leaked, it becomes Exhibit A in a very long document.”

Amazon’s market position in the US remains formidable: third-party sellers accounted for 61% of Amazon’s unit sales in 2025, generating approximately $147 billion in gross merchandise value. Any arrangement that structurally disadvantages those sellers — who are also Amazon’s customers — would carry serious regulatory surface area.

What Should Sellers Do Right Now?

Until Helium 10 or Amazon issues a formal statement, sellers are operating on unconfirmed information. But several operators and agency leaders told Ecommerce Times they are not waiting for clarity before taking precautionary steps. The recommended actions circulating in senior seller circles right now include:

• Reviewing the ToS and privacy policies of every research tool in your stack — specifically the data-sharing and third-party partner clauses
• Rotating product research across multiple platforms rather than concentrating in a single tool, to reduce the signal density any one platform can derive from your behavior
• Consulting legal counsel about whether existing tool agreements grant rights you did not intend to extend
• Watching SmartScout, DataHawk, and Seller.Tools as potential alternatives if Helium 10’s data practices become formally confirmed
• Escalating the conversation with your Amazon Seller Central account manager, if you have one, to formally request clarification on Amazon’s data sourcing policies

Ecommerce Times will continue tracking this story as it develops. A formal request for comment has been submitted to Helium 10’s communications team, Assembly’s PR agency, and Amazon’s Selling Partner Communications group. None had responded by publication time.
