Marketplace Strategy

Walmart vs Amazon: Where Should Your Brand Focus in 2026?

By SellTru · April 2026 · 7 min read

Most brand owners treat this like a binary choice. Either they've been on Amazon for years and can't imagine prioritizing anything else, or they hear about Walmart's rapid growth and wonder if they're leaving money on the table.

Here's the real answer: the question isn't which one — it's which one first, and how fast can you get to both. The brands that win in 2026 are not picking a side. They're running a dual-channel marketplace strategy with proper attention on each platform.

Let's break down exactly what that looks like.

Amazon Still Dominates — But the Math Has Changed

Amazon controls roughly 40% of US ecommerce. That's not going anywhere. But what has changed is the cost to compete. Sponsored Products CPCs have risen steadily across nearly every category. Consumer goods, supplements, home, and beauty are genuinely saturated. New fee structures have compressed margins. And the platform keeps moving — stricter compliance requirements, more complex inventory management, changing ranking signals.

None of this means Amazon isn't worth it. A well-managed Amazon account for a brand doing $3M in revenue can still generate serious returns. But "just being on Amazon" is no longer enough. You need optimized listings, a real Amazon PPC strategy, and active account management to hold ground, let alone grow.

If your Amazon account is not being actively managed right now, competitors are eating your market share. That's not a scare tactic — it's just how the algorithm works. Rankings erode. Ad placements shift. BSR drops quietly over weeks, not overnight.

Walmart.com Is Not What It Was Three Years Ago

Walmart.com surpassed $23 billion in US ecommerce sales in 2025. Their third-party marketplace has grown significantly, Walmart Fulfillment Services (WFS) has become a genuine FBA alternative, and Walmart Connect advertising now offers Sponsored Products, Sponsored Brands, and display options that simply didn't exist a few years back.

More importantly: competition on Walmart is still dramatically lower than Amazon. In many categories, ranking on page one of Walmart search requires a fraction of the ad spend you'd need on Amazon for the same placement. That gap is closing — but it's still very real.

The Walmart marketplace opportunity is particularly strong for brands in categories like household essentials, food and grocery, personal care, and pet. Walmart's customer base skews toward value-conscious buyers who often won't shop Amazon first — meaning Walmart isn't just a backup channel, it's a different customer entirely.

Four Questions to Figure Out Where You Stand

Before deciding where to focus your energy and budget, answer these honestly:

1. How healthy is your Amazon account right now? If your ACOS is above 35%, your listings haven't been updated in months, and you can't tell me your top five converting search terms — Amazon needs work before you expand anywhere else.
2. Are you eligible for Walmart Marketplace? Walmart is invite-based with a review process. They look at brand legitimacy, existing sales history, and product quality. If you're already selling on Amazon with solid metrics, your approval odds are good.
3. What's your fulfillment setup? Walmart prioritizes WFS sellers in their search algorithm, similar to how FBA products get a boost on Amazon. If you're already using FBA, the transition to WFS is far less complicated than most brands expect.
4. How competitive is your category on each platform? Search your core keywords on both Amazon and Walmart. Look at who is actually on page one. If Walmart's page one is full of weaker brands and unoptimized listings, that is an opportunity signal.

When to Keep Amazon the Priority

Amazon should stay your primary focus if any of these are true for your account:

• Your revenue is inconsistent or declining and you don't know the root cause
• Your PPC has no negatives, no campaign segmentation, and you're not reviewing search term reports
• Your listings haven't been updated in the last 90 days
• You haven't set up A+ Content or Brand Story
• You have open compliance cases, suppressed listings, or account health issues

Fix the foundation first. Expanding to Walmart won't save a leaking Amazon account — it just gives you two problems instead of one.

When Walmart Deserves Real Investment

If your Amazon account is in good shape — consistent revenue, managed advertising, strong content — Walmart is the logical next move. Specifically, Walmart makes sense when:

• You're in a category with heavy Amazon competition and rising CPCs
• Your products compete on value as well as brand (Walmart's core customer cares about both)
• You're doing $1M or more on Amazon and want to diversify channel risk
• You have inventory that's eligible for 2-day shipping or WFS

The brands seeing the strongest Walmart growth right now treated it like a serious channel from the start — optimized listings, structured ad campaigns, WFS for fulfillment. Not an afterthought. Not a copy-paste of their Amazon catalog with no changes. (If you're new to Walmart advertising, see our breakdown: Does Walmart have PPC advertising?)

The Case for Running Both Simultaneously

Here's the practical reality most agencies won't tell you: Walmart requires roughly 20% of the ongoing management effort that Amazon does. The ad platform is less complex. Listings are simpler to build and maintain. The algorithm is more straightforward. For a brand that already has content assets, product data, and a fulfillment operation built around Amazon — getting live on Walmart is achievable in 30 to 60 days.

And once it's running, it just adds revenue. Walmart customers who won't buy on Amazon do buy on Walmart.com. The audience overlap between the two platforms is smaller than most people assume, especially in home goods, health, and grocery-adjacent categories.

We've seen brands add 15–25% in incremental revenue within the first six months of going live on Walmart — with margins that beat their Amazon numbers, because the advertising costs are still so much lower.

The Bottom Line on Amazon vs Walmart in 2026

Amazon first, always. If your account isn't healthy, that's where the fix has to start. But don't wait for "perfect" before starting the Walmart conversation — that moment never comes. The competitive advantage on Walmart is real, and it is shrinking as more brands wake up to it.

The dual-channel marketplace strategy isn't a future goal for brands at scale. For brands doing $1M to $20M in revenue, it's the right play now.
