If you already sell on Amazon, expanding to Walmart Marketplace is one of the highest-leverage moves you can make in 2026. You've already got the hard parts — sourcing, inventory, operations — and Walmart offers a less crowded marketplace with no monthly fee to plug them into. This guide walks through why it's worth it and how to actually do it.
Why Amazon sellers should expand to Walmart
You already know how to run a marketplace business. Walmart lets you reuse that engine on a channel with structural advantages Amazon no longer has:
- Far less seller competition. Listings that have a dozen sellers on Amazon often have two or three on Walmart — easier Buy Box, slower price erosion.
- No monthly subscription. Amazon charges $39.99/month before you sell anything; Walmart charges nothing to list. Your downside to testing is near zero.
- A less saturated data landscape. On Amazon, everyone uses the same research tools and sees the same numbers. On Walmart, accurate product research is still a real edge.
- Diversification. A second channel protects you from a single Amazon suspension or policy change wiping out your revenue.
The honest trade-offs: Walmart's total volume is smaller than Amazon's, approval is stricter, and demand data is harder to read without the right tools. All manageable — and the last one is solvable. (We compare the platforms in full in Amazon vs Walmart selling.)
Step 1 — Apply for Walmart Marketplace
Walmart requires an application: business details, tax/EIN information, and proof you can fulfill orders reliably. Standards are stricter than Amazon's open registration, but the process has loosened from the invite-only early years. Having an established Amazon track record helps. Apply early — approval can take time.
Step 2 — Decide your fulfillment
You have two paths on Walmart:
- WFS (Walmart Fulfillment Services) — Walmart stores and ships for you, similar to FBA. Best for small, light, fast-moving items, and 2026 includes new-seller WFS fee discounts. (See FBA vs WFS.)
- FBM (self-fulfilled) — you ship yourself. Better for bulky or slow items. (See WFS vs FBM.)
Many Amazon sellers run FBA on Amazon and WFS on Walmart in parallel, keeping inventory pools separate.
Step 3 — List your catalog
You can often map your existing Amazon catalog to Walmart, but don't just copy-paste:
- Match to existing Walmart listings where they exist (you'll join as a seller on that listing rather than create a duplicate).
- Re-optimize titles and content for Walmart's style — Walmart's search and content guidelines differ from Amazon's. Don't carry over Amazon-specific phrasing or claims.
- Re-check category and fees. Walmart's referral fees (6–20%, most 15%) and category assignments aren't identical to Amazon's. Recalculate margin per product before listing. (Full structure: Walmart seller fees 2026.)
Step 4 — Re-validate demand on Walmart (don't assume)
This is the step Amazon sellers most often skip — and it's a mistake. A product that sells well on Amazon doesn't automatically sell well on Walmart. Different audience, different competition, different demand. And Walmart doesn't publish a Best Sellers Rank, so you can't read demand the way you read Amazon BSR.
Before you commit inventory to a Walmart listing, estimate its Walmart demand on its own terms — via review velocity, seller count, and price history, or with a Walmart sales estimator. (Methods here: how to estimate Walmart sales.)

Step 5 — Win the Buy Box
Walmart's Buy Box (the default "Add to Cart" seller) weighs price heavily, along with fulfillment speed and seller performance. With fewer competitors than Amazon, winning it is often easier — but price discipline still matters. Use price history to avoid pricing against a temporary spike, and let WFS's fast delivery work in your favor on contested listings.
The mistakes Amazon sellers make on Walmart
- Assuming Amazon winners are Walmart winners. Re-validate demand per product.
- Copying Amazon listings verbatim. Walmart's content rules and search differ.
- Reusing Amazon fee math. Walmart's referral tiers and WFS fees aren't the same.
- Ignoring price history. Without it, you can't tell a real Walmart price from a spike.
- Treating Walmart as an afterthought. The sellers who win give it real attention — and reap the lower-competition upside.
Frequently asked questions
Can Amazon sellers sell on Walmart? Yes. Many Amazon sellers expand to Walmart Marketplace to reach a less competitive channel with no monthly subscription fee. You'll apply separately and meet Walmart's seller standards, but your sourcing and operations carry over.
Is it hard to expand from Amazon to Walmart? The operational side is straightforward if you already run an Amazon business. The main work is getting approved, re-optimizing listings for Walmart, recalculating fees, and re-validating demand — since Walmart's audience and data don't mirror Amazon's.
Will my Amazon best-sellers sell on Walmart? Not automatically. Walmart has a different audience and competitive landscape, and no public Best Sellers Rank. Estimate each product's Walmart demand independently before committing inventory.
Can I use the same inventory for Amazon and Walmart? With WFS and FBA you keep separate inventory pools at each platform's warehouses. With self-fulfillment (FBM) you can ship both channels from your own stock. Many sellers run FBA + WFS in parallel.
