Amazon has removed the seller eligibility requirement that previously filtered which sellers' offers were even considered for the Featured Offer, commonly known as the Buy Box. Starting in July 2026 and rolling out globally through the end of the year, every seller's offer on a product listing is now ranked directly on price, delivery speed, and account performance — with no eligibility pre-screen. At Adorbix, we work with Amazon sellers every day, and this is one of the more consequential ranking changes we've seen this year: it means increased competition for Buy Box share, especially from competitors who were previously screened out entirely.

What Changed: A Two-Step Process Becomes One Step

Before this update, Amazon's Buy Box algorithm worked in two stages. First, it checked which sellers met baseline eligibility criteria (account health, performance history, and other seller-level metrics). Only sellers who cleared that bar had their offers considered at all. Second, among those eligible sellers, Amazon ranked offers by competitive pricing, delivery speed, and other customer-facing factors to award the Featured Offer

Amazon has now removed step one. According to the official announcement on Amazon Seller Forums, the company determined the seller eligibility step was "no longer delivering additional value to customers." Every offer on a listing is now evaluated in the single remaining stage, ranked on the same customer-facing criteria as before: competitive pricing, delivery speed, and performance.

‍

Why Amazon Made This Change

Amazon's stated rationale is that the eligibility filter had become redundant — the downstream ranking criteria (price, delivery, performance) already accounted for the same signals the eligibility gate was checking, just at the individual-offer level rather than as a blanket seller-level cutoff. Removing the redundant step, in Amazon's framing, surfaces more competitive offers to customers.

What This Means for Amazon Sellers

• Established sellers who benefited from the eligibility gate may see new competitors appear on listings where they previously had little or no competition for the Buy Box
• Sellers who were previously excluded from Featured Offer consideration despite strong pricing or fast delivery now have a direct path to winning it.
• Buy Box share is likely to become more volatile in the short term as the rollout completes across marketplaces through the end of 2026.
• Pricing, delivery speed (especially FBA vs. FBM), and seller performance metrics matter more than ever, since they are now the only gate that exists.

How Adorbix Is Helping Clients Protect Buy Box Share

We're treating this as a prompt to audit pricing competitiveness and delivery speed now, rather than waiting for share to erode. For our clients, that means monitoring Buy Box percentage daily during the rollout window, tightening repricing strategy, and shoring up account health metrics (order defect rate, late shipment rate, valid tracking rate) — since eligibility can no longer act as a backstop.

‍

Key Takeaways:

• Amazon removed the seller eligibility gate for the Featured Offer (Buy Box) starting July 2026, rolling out globally through year-end.
• All seller offers on a listing now compete directly on price, delivery speed, and performance — no pre-screening step.
• No seller action is technically required, but Buy Box share may shift as new competitors surface.
• Sellers should audit pricing, delivery speed, and account health metrics now to defend existing Buy Box share.
