Amazon's 1,000-Warehouse Plan: What FBA Sellers Do Now

What the Reported Plan Actually Says

The reported plan is a build-out, not a policy. Here is what the documents reportedly describe, and what they do not.

• Amazon reportedly aims for more than 1,000 same-day fulfillment centers in the U.S. by 2031, up from roughly 85 today.
• The stated network goal is to put a same-day facility within 10 miles of 80% of U.S. Prime members by 2031.
• The initiative is internally called Project Mercury. A smaller facility design is internally called Orbital.
• The Orbital design reportedly covers roughly 100,000 square feet and would process about 75,000 same-day and perishable units daily.
• Same-day facilities reportedly stock about 90,000 popular products, which is far fewer than a full FBA fulfillment center holds.
• Reported categories of focus are groceries, household supplies, medicine, and other frequently purchased goods.

The report is dated September 16 and the article was last updated September 16, 2026. Amazon told investors its same-day perishable service attracted more monthly customers and larger baskets, per Q2 comments. An Amazon spokesperson confirmed the company is investing in faster delivery while warning the figures may change.

What the plan does not say matters just as much. There is no announced seller fee, no enrollment program, and no new inventory rule tied to it. Amazon has not stated how products would qualify for these facilities. The 90,000 products, 100,000 square feet, and 75,000 units per day are all internal estimates, not guarantees.

Why Regional Beats National In-Stock

The single most useful idea in this report is simple. Speed is a function of location. A unit cannot get a very fast delivery promise if it is not positioned near the customer.

Most sellers watch national in-stock status. That number can look green while a buyer in one region still sees a slower delivery date because the nearest unit is far away. National in-stock may indicate less than regional availability for delivery speed. If same-day coverage keeps growing, the gap between "in stock nationally" and "in stock near this buyer" becomes more important.

• Delivery promise is set per buyer, based on where stock actually sits.
• A faster promise can lift conversion in that region, so a slower promise can quietly cost you sales.
• Amazon already charges sellers to distribute inbound inventory across parts of its network, which is the current lever for placement.

To be clear, there is no proof that Amazon will change the Featured Offer formula, storage limits, or placement fees because of this plan. Any of those would need a separate announcement. The point is to start thinking in regions, not just national totals.

Which ASINs Benefit From Speed Badges

Not every product cares about same-day. Some do. The way to find out is to measure, not guess. Amazon already shows different delivery speeds on different listings, so the data is sitting in front of you.

• Measure conversion differences between listings where Amazon already shows different delivery speeds. That tells you how much speed moves the needle for your buyers.
• Track stockout days, lost Featured Offer time, and inbound lead time per ASIN. Slow inbound and frequent stockouts hurt fast-delivery eligibility.
• Flag ASINs with steady, repeatable demand. These are the ones where a faster promise is likely to pay for itself.

The goal is a short list of ASINs where faster delivery clearly lifts conversion. Those are the products worth positioning more aggressively if regional coverage expands. Everything else can wait.

Category Fit: Everyday vs Long-Tail

Same-day facilities are small. They reportedly stock about 90,000 popular products and focus on things people buy again and again. That shapes which of your products fit.

The reporting names groceries, household supplies, medicine, and other frequently purchased goods as the focus. Amazon has not published a full or final list of eligible categories, so confirm current details on Amazon's own pages before you plan around any one category. Identify your replenishable products with steady local demand as best-fit candidates, and do not try to force slow movers into a local-speed strategy.

Modeling True Landed Cost

Faster delivery can lift conversion. It can also add cost, because Amazon already charges to distribute inbound inventory across parts of its network. More conversion at a higher cost per unit is not always a win. You need to check the math per ASIN.

Model landed cost to confirm faster conversion yields more contribution dollars after any added fees. The test is contribution, not revenue. Plenty of sellers chase a speed badge and end up with more orders and less profit.

• Start with your current landed cost per unit and current conversion.
• Review current inbound placement fees and how they stack per order, since that is the cost lever Amazon uses today.
• Estimate the conversion lift from a faster promise using your own speed-vs-conversion data, not a guess.
• Compare contribution dollars per unit before and after. If the number goes up, positioning that ASIN closer is worth it. If it goes down, leave it.

If you already run this kind of math for peak season, the muscle is the same. Our breakdown of how Amazon Q4 fees stack up on true landed cost walks through the same contribution-first thinking.

Consolidate or Spread Framework

The core decision is whether to keep inventory in fewer places or push it closer to buyers across regions. There is no single right answer. Split your catalog and decide per group.

• Spread candidates: predictable repeat-demand ASINs with a clear conversion lift from faster delivery. These reward being close to buyers.
• Pool candidates: slow, unpredictable, or long-tail ASINs that need a national inventory pool to avoid stranded units in the wrong region.

Separate predictable-repeat-demand ASINs from those needing a national pool. Avoid forcing every ASIN into a local-speed strategy, because that is the fastest way to create stranded inventory you cannot sell in the region it sits in. And do not change your inbound plan solely because of a 2031 projection. Build the framework now, act when there is something concrete to act on.

How AWD and Upstream Stock Fit

A more regional future rewards holding bulk stock upstream and topping up local FBA based on demand. That keeps your fast-selling units close to buyers without committing your whole catalog to regional placement too early.

• Keep bulk stock upstream where economical and replenish FBA based on actual demand signals.
• Review how much you currently rely on Amazon Warehousing and Distribution and whether it lets you replenish faster.
• Build better regional demand forecasting capability now. If placement gets more granular, sellers who can forecast by region will make smarter calls than those working off national totals.

This is a capability, not a one-time task. The sellers who win here are the ones who can see demand by region and move stock quickly, whatever Amazon decides about fees.

A This-Week Data Checklist

No deadline exists. But you can do useful work this week that pays off whether or not the plan happens. All of it is data you should have anyway.

Do this once and you have a clear picture of your catalog. If Amazon announces anything real, you move in a day instead of a month.

Speed Is Nothing Without Conversion

Here is the part sellers skip. A faster delivery badge gets a buyer to look. The listing still has to close the sale. If your title is weak, your bullets are vague, or your keywords are missing, speed just brings more people to a page that does not convert.

• A faster promise increases the value of every click, so weak listings waste more traffic, not less.
• The ASINs you flag as best-fit for regional placement are exactly the ones whose listings should be airtight first.
• Better copy and stronger keyword coverage lift conversion on their own, before any delivery change.

Get the listing right and the speed advantage compounds. For the full method, see our complete walkthrough of Amazon listing optimization. And if you want to understand how availability and delivery tie into the Buy Box, read what wins the Amazon Buy Box in 2026.

Conclusion

The reported 1,000-warehouse plan is real reporting about internal documents, but it is not a policy you must react to. Amazon said the numbers are preliminary and may change. Nothing about your fees, storage limits, or Featured Offer changes today.

So do the smart thing. Understand that speed follows placement. Build the data to know which ASINs gain from faster delivery. Model your landed cost so more orders mean more profit, not less. Keep bulk stock upstream and forecast by region. Then, if Amazon announces something concrete, you act from a position of knowledge instead of panic.

While you are at it, make sure your best-fit listings actually convert. Our guide on how to fix low conversion rates on your Amazon listings is a good next step for the products you plan to position closer to buyers.
