Walmart

Nine dimensions merchants should review before joining:

Merchant snapshot

The third pole of US e-commerce as a marketplace, with omni-channel + grocery advantages and overall lower fees than Amazon. FY25 company revenue was $681.0B (+5.1%); global e-commerce grew +16% and e-commerce was about 18% of Q4 sales (Walmart FY25). US e-commerce GMV is not disclosed — a ~$15B figure is third-party (3P) GMV only and conflicts with the ~7% US share implied scale. Best for mature cross-border sellers with US warehousing or WFS; the seller ecosystem is still weak versus Amazon.

Entry requirements

Marketplace onboarding is review-based: you need a company business license (a US company or a qualified international company), tax information, and a logistics plan, with a relatively long review cycle; 200K+ sellers in 2025 but a rumored "seller exodus" and quietly adjusted third-party incentive programs (Ecommerce Times). No monthly fee and no per-item fee (threecolts Sept 2025 comparison); international sellers must provide US local fulfillment or use WFS.

Fee structure

No subscription/monthly or per-item fees — only category-based referral fees: e.g., apparel (>$20) 15%, computers 6%, musical instruments 12%, printer ink cartridges 12% (threecolts Sept 2025: on par with or lower than Amazon for the same categories); WFS fulfillment fees are significantly lower than FBA in some categories (individual fee items ~80% lower), but FBA is more cost-effective for small items (<$10). Walmart Connect ads are bid-based. For specifics, refer to the official fee schedule.

Getting traffic

Walmart.com on-site search plus Walmart Connect ads (growing ~6x faster than sales, na_platforms.md); Walmart+ membership and store traffic work together, with store-based fulfillment covering 93% of US households with same-day delivery; the #1 US grocery e-commerce customer base is extending into non-grocery and advertising. Platform effects and seller tools are weaker than Amazon's, organic traffic scale is limited, and sellers must bring price/product-selection advantages.

Fulfilment & logistics

WFS (Walmart Fulfillment Services) is Walmart's 3P fulfillment network: it handled about 45% of marketplace orders in Q4 FY25. International sellers without a US warehouse must use WFS or another local fulfillment plan — there is no Amazon-style pan-regional FBA equivalent outside the US. The core differentiator is store-as-warehouse omni-channel fulfillment (same-day delivery/pickup covering 93% of US households). Sellers can also self-fulfill subject to delivery-time SLAs. Shipping/storage is billed by volume and duration (official Pricing page), with additional fees for Big & Bulky items. Walmart's global footprint (US, Mexico, Canada, Chile, China sourcing) does not mean a single WFS pool: marketplace GMV and WFS capacity are US-centric, and country sites are separate onboarding/compliance tracks.

Payments & settlement

The platform collects payments centrally with USD settlement; sellers link a US bank account or third-party payout services (Payoneer/WorldFirst, etc.); settlement cycles follow platform policy (typically several weeks); fees and ad costs are deducted from settlement.

Compliance

US sales tax is collected by the platform or registered by the seller; products must meet CPSC/CPC and other safety certifications and Walmart's restricted-product policies; WFS items must comply with packaging and dangerous-goods rules; in 2025 Walmart launched AI seller tools and new store-linked regulations (Retail Dive). The platform does not disclose US e-commerce GMV or e-commerce segment profit, so sellers must monitor account health themselves.

Key risks

1) Weak seller ecosystem: the "seller exodus" rumors and incentive-program adjustments undermine the "Amazon alternative" narrative; 2) 3P scale is far smaller than Amazon (3P is only ~10% of e-commerce GMV), with clear gaps in assortment depth and in tools/ads/logistics systems; 3) opaque data: US e-commerce GMV is not disclosed ("~$15B" is only the 3P figure, conflicting with the scale implied by a ~7% share); 4) the balance between e-commerce fulfillment/delivery costs and profitability (continued 1-hour/same-day investment).

Best-fit sellers

Best for mid-to-large cross-border sellers that already have US warehousing/local delivery capability and sell grocery, home, daily consumer goods, baby products, and apparel, as a lower-fee supplementary channel outside Amazon; grocery supply-chain sellers have a natural edge. Not suitable for small new sellers without a US fulfillment plan who want rapid volume, nor for brands that need rich seller tools/ad ecosystems.
