How to Sell on Walmart Marketplace: 2026 Approval & Launch Guide

Walmart Marketplace now drives billions in third-party sales with far less competition per listing than Amazon — but Walmart is selective about who sells.

Approval favors sellers with marketplace history, GTIN-compliant catalogs, and fast US fulfillment. Your application should demonstrate operational maturity: existing revenue, low defect rates, and clear category focus.

After approval, your first 90 days determine your trajectory. Prioritize listing quality scores, join Walmart Fulfillment Services for the 2-day delivery tag, and price competitively — Walmart suppresses listings priced above other channels.

A managed launch avoids the common traps: attribute errors that bury listings, pricing violations, and early ODR breaches that can suspend a new account.
