House Bill Would Force Marketplaces to Explain Account Bans and Limit Inventory Holds

What the Bill Demands of Amazon and Other Marketplaces

A new bill introduced in the U.S. House of Representatives seeks to fundamentally change how major ecommerce platforms police their sellers. The "Online Sellers’ Bill of Rights Act of 2026" (H.R. 9799), sponsored by Rep. Becca Balint (D-Vt.) and a group of co-sponsors, would require marketplaces such as Amazon and Walmart to provide individualised explanations when they suspend accounts or listings, set strict time limits on freezing inventory and funds, and give merchants a genuine opportunity to appeal.

At the heart of the legislation is the notion that a mere allegation should not be enough to cripple a small business. Under the bill, a marketplace would have to disclose the exact policy the seller supposedly violated, share the relevant facts or documents, describe the proposed penalty, and explain the appeals procedure—along with an expected timeline for resolution. Inventory holds in counterfeiting cases could last no more than 30 days unless the platform could produce clear evidence the goods were actually unlawful. Similarly, money from suspended accounts would have to be released unless the marketplace could demonstrate, with proof, that the funds came from illegal transactions.

The bill also tackles retrospective rule changes. If a platform decides to bar a product that it had previously accepted into its fulfilment network, it would need to give the seller at least 30 days to sell off the remaining stock or ship it back at no cost. And any material change to fees, commissions, listing requirements, or product eligibility would require a written notice period of at least 30 days. Platform operators would retain the ability to remove fraudsters and counterfeiters—the bill is not a free pass—but they would have to show their homework before pulling the plug.

Enforcement would not rely on goodwill alone. The Federal Trade Commission would have 180 days after enactment to issue rules, and violations would be treated as unfair methods of competition. State attorneys general could sue, and injured sellers could file private suits in federal court even if their marketplace agreement mandates arbitration. A winning seller could recover three times the actual damages plus legal costs, a provision that trade groups representing small online merchants have long demanded.

The Legal and Competitive Calculus Behind the Bill

The proposal lands at a moment when thousands of third-party sellers feel they are at the mercy of opaque platform algorithms and unilateral enforcement decisions. Beyond the immediate operational changes, the bill carries profound legal and competitive implications.

Who Is Really a ‘Dominant Platform’?

The legislation defines a “critical trading partner” as one that can restrict a business’s access to customers or the tools needed to serve them—a deliberately broad phrase. Yet the obligation to follow the new rules falls on businesses selling on a “dominant platform.” The bill does not set any revenue, transaction, or market‑share threshold. That ambiguity is likely deliberate, but it creates uncertainty. Amazon and Walmart are clearly in the crosshairs, while eBay, Etsy, Poshmark and smaller specialised marketplaces might escape or be drawn in, depending on how the FTC eventually interprets “dominant.” Without a bright‑line test, legal challenges are almost certain, as platforms argue the term is unconstitutionally vague.

The Arbitration End‑Run

One of the bill’s most aggressive features is its override of mandatory arbitration clauses, which nearly every large marketplace uses to keep disputes out of court. By guaranteeing sellers a private right of action and treble damages, the legislation would fundamentally shift the bargaining power. A marketplace that suspends a seller without a detailed, evidence‑backed explanation could face a federal lawsuit with the prospect of triple damages—an incentive that changes the risk calculus for in‑house legal teams. Expect platform operators to fight this provision fiercely, arguing it undermines a cornerstone of online contracting.

Winners, Losers and Strategic Moves

Legitimate sellers with sound compliance records stand to gain a powerful new tool. The ability to demand rapid inventory release and a transparent decision‑making process could reduce the number of businesses destroyed by sudden, unexplained suspensions. On the other hand, the platforms will have to invest heavily in compliance, training, and legal review, raising their operating costs. Smaller marketplaces that are not classified as dominant might see an influx of sellers seeking a less regulated environment—a competitive dynamic that could pressure Amazon and Walmart to differentiate on fairness. Consumer advocates will watch whether the 30‑day inventory hold and detailed notice requirements inadvertently slow down the removal of truly unsafe or counterfeit products, a concern the billguardians acknowledge by requiring evidence before a hold can be extended.

What Marketplace Sellers Should Expect Next

• If you sell on Amazon or Walmart, track H.R. 9799’s progress through the House Judiciary Committee. Should it become law, you could demand an immediate, detailed explanation for any suspension and a 30‑day cap on inventory holds unless the platform can prove your goods are counterfeit.
• Review your compliance posture now. While the bill is designed to make enforcement fairer, nothing in it prevents a marketplace from suspending you for a genuine policy violation. A strong internal audit of your listings, sourcing documentation, and account health can put you in a stronger position to appeal swiftly if needed.
• If you have been suspended unfairly in the past, consult legal counsel about whether the bill’s prospective remedies would strengthen any existing claim. The private right of action with treble damages would apply only to future violations, but the political momentum it creates could influence the platforms’ current settlement practices.
