Amazon vs Walmart Marketplace: which channel should you sell on first?
For most brands selling in the United States this is not really a choice between two marketplaces. It is a choice about sequencing, margin and how much operational load your team can absorb. Here is how the two channels compare on the eight things that decide whether a marketplace makes you money.

Brands & sellers
Marketplace choice is a demand and margin decision before it is a listing decision.
THE SHORT ANSWER
Amazon is where the demand is. Walmart is where the head-room is.
If you need volume and your category is already established online, Amazon is almost always the first channel, because that is where the buyers are searching. If your margin is thin, your category is competitive, or you want a channel where a well-run listing still stands out, Walmart is the better place to put your effort. Most brands we work with end up on both, in that order, roughly a year apart.
Start with Amazon if
More demand
You need volume quickly and your product can carry the fee and advertising load that comes with a crowded channel.
- Your category has clear, established search demand on Amazon
- Your margin can absorb referral fees plus meaningful ad spend
- You want fulfilment and delivery expectations handled for you
- You have the content and imagery to compete on a busy results page
- You are ready to manage reviews, account health and competitors closely
- International marketplaces are on your roadmap after the United States
Start with Walmart if
Less crowded
You want a channel where good listing work and sensible pricing still move the needle without an advertising arms race.
- Your category is saturated on Amazon and margin is already tight
- Your products suit a mainstream, price-aware customer base
- You want a channel with fewer sellers competing for the same buy box
- You can meet the delivery speed expectations the channel enforces
- You have the catalogue data quality the listing system rewards
- You are prepared for a slower start in exchange for cheaper visibility
Running both is normal and often correct. If you are considering it, read round 08 on operational load before you commit.

ROUND 01
2 min
Demand, traffic and category fit
Marketplace success is mostly a demand question. A brilliant listing in a channel where nobody searches for your category will lose to an average listing where they do.
Start from where your category already sells, not from which platform you prefer.
Amazon
- The default starting point for United States product search
- Deep demand in almost every consumer category
- Buyers arrive ready to purchase rather than to browse
- Established categories mean predictable search behaviour
Watch out: Demand and competition arrive together. High search volume in your category usually means high advertising costs too.
Walmart Marketplace
- A large and growing audience, weighted toward everyday categories
- Strong performance in grocery, household, home and value segments
- Shoppers who cross over from a physical retail relationship
- Fewer competing sellers chasing the same search terms
Watch out: Some premium and niche categories have materially thinner demand here. Check yours before you invest in listings.
THE EDGE — AMAZON
On raw demand this is not close. The useful question is not which channel is bigger, but whether your specific category has enough demand on Walmart to justify the setup work. For most mainstream consumer categories it now does.
ROUND 02
3 min
Fees, margin and the real economics
Referral rates on the two marketplaces are broadly comparable by category. The difference in what you actually keep comes from the account cost, the fulfilment model and how much advertising it takes to be seen.
Model the full landed cost per order before you list anything on either channel.
Amazon
- A monthly professional selling plan on top of referral fees
- Referral fees vary by category and are published openly
- FBA storage and fulfilment fees, including long-term storage charges
- Advertising is close to mandatory in competitive categories
Watch out: The line that surprises people is advertising. In a crowded category it can exceed the referral fee.
Walmart Marketplace
- No monthly seller subscription, which lowers the cost of testing
- Referral fees by category, in a similar range to Amazon
- WFS fees if you use Walmart fulfilment, or your own logistics cost
- Advertising is optional for longer, and usually cheaper per click
Watch out: Pricing rules mean an item priced higher than elsewhere online can be suppressed, which quietly caps your margin.

Fee structure rather than fee amounts. Both marketplaces publish current rates and revise them; model your own numbers from their published schedules.
MODEL IT PROPERLY
The mistake we correct most often is modelling marketplace margin on referral fees alone. Add fulfilment, storage, returns and the advertising cost of actually being visible, then decide whether the channel works. Our article on why ROAS reports hide margin problems covers the same trap in advertising reporting.
THE EDGE — WALMART ON COST TO ENTER
Walmart is cheaper to test and cheaper to be visible on. Amazon usually returns more per unit of effort once you are established. If capital is tight, the lower entry cost is a real advantage rather than a rounding difference.
ROUND 03
2 min
Getting approved and getting listed
Amazon lets almost anyone start and then gates the categories that matter. Walmart reviews you first and is more forgiving afterwards. Both punish poor catalogue data, in different ways.
Catalogue data quality decides how painful the first ninety days are on either channel.
Amazon
- Registration is open and you can be listing quickly
- Category gating and brand approvals sit behind that
- Brand Registry unlocks the tools you actually need
- Matching against existing catalogue entries can create conflicts
Watch out: Getting listed is fast. Getting listed correctly, with your brand controlling the detail page, takes longer.
Walmart Marketplace
- An application is reviewed before you are approved to sell
- Business documentation and product data are assessed up front
- Item setup is strict about attributes and required fields
- Fewer sellers means less catalogue collision on your items
Watch out: Item setup failures are the standard first-month problem. Clean, complete product data is not optional here.
THE EDGE — AMAZON ON SPEED
Amazon gets you trading sooner; Walmart gets you a cleaner catalogue. Whichever you choose, the work that pays for itself is fixing product data before you upload rather than after items are rejected.
ROUND 04
2 min
Listings, content and catalogue quality
Both marketplaces rank on relevance and convert on content. Amazon has the deeper toolset. Walmart is more transparent about what it wants from you.
The same product data feeds both channels, but each rewards different detail.
Amazon
- Enhanced brand content and brand stores for registered brands
- Structured titles, bullets and backend search terms
- Video, comparison modules and rich media on the detail page
- Reviews carry enormous weight in both ranking and conversion
Watch out: You share the detail page. Other sellers, and Amazon itself, can affect how your product is presented.
Walmart Marketplace
- A published listing quality score that tells you what to fix
- Attributes and specification completeness drive discoverability
- Rich media support has improved substantially
- Fewer competing listings means good content stands out longer
Watch out: Review volume builds more slowly here, so early conversion depends more on content than social proof.
THE EDGE — AMAZON ON TOOLING
Amazon gives a brand more ways to control presentation. Walmart gives clearer feedback on what is wrong. Teams that struggle with prioritisation often make faster progress on Walmart because the scorecard tells them where to start.
ROUND 05
2 min
Advertising and paid visibility
Marketplace advertising is now the main lever for visibility on both channels. The platforms differ in maturity, in cost, and in how much reporting you get back.
Advertising cost is the difference between a marketplace that works and one that only looks busy.
Amazon
- The most developed retail media platform available to sellers
- Sponsored product, brand and display formats with real targeting
- Reporting deep enough to manage to a target ACoS by product
- Off-platform and audience options for established brands
Watch out: Competitive categories bid costs to a level where only strong margin or strong conversion survives.
Walmart Marketplace
- Walmart Connect covers the core sponsored formats
- Cost per click is generally lower than the Amazon equivalent
- Less competition means modest budgets still buy visibility
- Reporting and targeting are less granular than Amazon
Watch out: Fewer controls means less ability to fix a campaign that is spending in the wrong place. Watch it more closely.
If marketplace advertising is already running and you are not sure it is profitable at the contribution line, that is the first thing worth measuring.
THE EDGE — AMAZON ON CAPABILITY, WALMART ON COST
A large budget with a skilled team goes further on Amazon. A small budget goes further on Walmart. For brands entering a channel with limited spend, cheaper visibility is often worth more than better tooling.
ROUND 06
2 min
Fulfilment and delivery expectations
Both channels reward fast, reliable delivery and both offer their own fulfilment programme to provide it. The commitment you make here shapes your working capital as much as your logistics.
Delivery speed is a ranking and conversion factor on both marketplaces, not just a service level.
Amazon
- FBA is the practical default in most competitive categories
- Prime eligibility materially affects conversion
- Returns and customer service are absorbed by the programme
- Seller-fulfilled options exist but carry stricter performance metrics
Watch out: Inventory sitting in FBA is capital you cannot redeploy, and storage charges rise the longer it stays.
Walmart Marketplace
- WFS provides an equivalent hands-off fulfilment route
- Delivery speed programmes visibly affect placement
- Self-fulfilment remains genuinely viable if you are fast
- Fewer sellers competing on identical delivery promises
Watch out: Speed expectations are enforced. If your own logistics cannot meet them consistently, budget for WFS.
THE EDGE — AMAZON
FBA is the more mature network and Prime is a stronger conversion signal than anything Walmart currently offers. Walmart is the better option if you want to keep control of your inventory while still competing on delivery.
ROUND 07
2 min
Brand control, competition and the buy box
Both marketplaces are shared shelves. The difference is how many other people are standing on yours, and what you can do about them.
How much of your brand presentation you control differs sharply between the two channels.
Amazon
- Brand Registry gives real tools for protecting your listings
- The shared detail page means competitors can attach to your item
- Buy box competition is constant and price-sensitive
- Unauthorised sellers and counterfeits require active policing
Watch out: Brand protection on Amazon is an ongoing operational task, not a one-off setup step.
Walmart Marketplace
- Fewer sellers per item, so the shelf is less crowded
- Less unauthorised reselling activity in most categories
- Pricing rules push you toward parity with your other channels
- A good listing holds its position for longer
Watch out: Price parity rules can force pricing decisions across all your channels, not just this one.
THE EDGE — WALMART
Walmart is currently the calmer channel for brand control, largely because there are fewer sellers on each item. That advantage narrows as more sellers arrive, so it is a reason to establish yourself now rather than a permanent property of the channel.
ROUND 08
2 min
Operational load and running both
This is the round to read if you are tempted to launch both at once. Marketplaces do not fail because the strategy was wrong; they fail because nobody had time to run them.
The channel you can staff properly beats the channel that looks better on paper.
Amazon
- Account health, policy compliance and case work are continuous
- Inventory planning against storage limits needs real attention
- Advertising needs weekly management to stay profitable
- Competitor and pricing monitoring is effectively a standing job
Watch out: Amazon punishes neglect faster than any other channel. A suppressed listing can cost a month of momentum.
Walmart Marketplace
- Lower day-to-day intensity once the catalogue is clean
- Listing quality and item setup issues are the main workload
- Fewer competitive fires to fight week to week
- Performance standards on delivery and cancellation still apply
Watch out: Lower intensity encourages neglect. Accounts that are left alone here stall quietly rather than dramatically.
1
Launch one channel properly and get it to a stable, profitable baseline first.
2
Fix catalogue data centrally, once, so the second channel inherits clean product information.
3
Add the second channel only when the first no longer needs daily intervention.
4
Keep pricing decisions in one place, because both channels enforce competitiveness rules.
THE EDGE — WALMART ON LOAD
Walmart asks less of a team week to week. That is exactly why brands with limited resource often do better there, and why sequencing one channel after the other beats launching both in the same quarter.

A framework, not a scoring formula. Category, margin structure and team capacity change the answer more than any platform feature does.
Check demand before anything else
Look at whether your specific category has real search volume on each channel. Everything downstream depends on that answer, and it is the cheapest thing to check.
Model contribution, not revenue
Build the unit economics with referral, fulfilment, storage, returns and advertising included. If the number is negative at realistic ad cost, the channel is not ready for you yet.
Be honest about capacity
A marketplace needs a named owner and a weekly rhythm. If you cannot name that person today, launch one channel rather than two.

- Questions
Amazon vs Walmart Marketplace FAQs
The questions brands ask us most often when they are choosing a first or second marketplace.
Is Walmart Marketplace easier to succeed on than Amazon?
It is less competitive, which is not the same as easier. There are fewer sellers on each item and cheaper advertising, so good work is more visible. But the demand pool is smaller, item setup is stricter, and delivery expectations are enforced. Brands that succeed there tend to have clean catalogue data and realistic pricing rather than a bigger budget.
Should I sell on both at the same time?
Usually not at the same time. Launching two marketplaces in one quarter splits attention exactly when both need it most. Get one to a stable, profitable baseline, fix your product data centrally while you do it, then add the second. Most brands we work with are a year apart on the two launches.
Which one has lower fees?
Referral rates are broadly comparable by category. Walmart has no monthly seller subscription, which lowers the cost of entry, and advertising there is generally cheaper per click. Amazon typically returns more per unit of effort once you are established. Model both with fulfilment, storage, returns and realistic ad spend included before deciding.
Do I need to use FBA or WFS?
On Amazon, FBA is close to a practical requirement in competitive categories because Prime eligibility affects conversion so strongly. On Walmart, self-fulfilment remains viable if you can consistently meet delivery speed expectations. Both programmes tie up working capital in inventory, so the decision is financial as much as logistical.
How long does approval take on Walmart?
Walmart reviews applications before approving sellers, so it is slower to start than Amazon, where registration is open. Timelines vary and Walmart does not commit to a fixed window publicly. Having your business documentation and product data ready before applying is the part you control.
Will selling on Walmart hurt my Amazon performance?
No, but pricing rules connect the two. Walmart can suppress items priced higher than they are elsewhere online, which means your pricing decisions have to be made across channels rather than per channel. That is a planning constraint rather than a performance penalty.
What about our own store, does a marketplace cannibalise it?
Some overlap is real, but marketplaces mostly reach customers who were never going to find your site. The sensible approach is to treat the marketplace as an acquisition channel and use packaging, inserts and post-purchase email to move repeat purchases to your own store, where the margin is better.
