Walmart's third-party seller base grew approximately 20% in 2024. As Amazon fees rise and TikTok Shop matures, more sellers are diversifying onto Walmart Marketplace — and discovering that shipping infrastructure that works for Amazon doesn't always translate cleanly.
150,000+ active Walmart Marketplace sellers as of early 2025, up from ~100K in 2022. The growth is accelerating.
What makes Walmart Marketplace shipping unique
Walmart Marketplace has specific fulfillment requirements that differ from Amazon and Etsy:
- On-Time Delivery Rate (OTDR) — Walmart requires 95%+ OTDR or risks seller suspension
- Shipping speed promises — listings show estimated delivery dates; missing them hurts search ranking
- Carrier confirmation requirements — tracking must be submitted and show carrier acceptance within 24 hours
- No built-in fulfillment network — unlike Amazon FBA, Walmart WFS is optional; most sellers ship themselves
The rate shopping opportunity
Walmart Marketplace sellers can use any carrier — there's no restriction to USPS or UPS the way some platforms have. This means multi-carrier rate shopping is fully available. For a 3-lb package shipped from Ohio to California:
- USPS Ground Advantage: ~$9.80
- UPS Ground: ~$8.40 with a negotiated account
- FedEx Home Delivery: ~$8.10 with BYOCA
The difference compounds at volume. 500 packages/month × $1.50 average savings = $750/month, $9,000/year.
