Walmart’s Stores Now Fulfill 80% of Its Online Orders. Here’s Why That Matters for Q4 Pricing.
Walmart's physical stores aren't competing with its ecommerce business anymore. They're the infrastructure it runs on. CFO John David Rainey told analysts on the company's August 20 earnings call that stores now serve as “the last-mile fulfillment nodes for 80% of our e-commerce orders and 100% of our fast deliveries.” Combined with a $2.9 billion tariff refund the company is funneling directly into price cuts, this quarter reveals two things worth understanding if you're planning your own Q4 pricing and inventory strategy.
Stores Have Become Walmart's Ecommerce Backbone
“The role of our stores has evolved as our model has changed,” Rainey said. “The more omni we become, the more important our stores become, not less important, more important.” That's not just messaging. Between in-store purchases and digital fulfillment, Walmart is now transacting more unit volume through its stores than at any point in the company's history.
The infrastructure behind that shift is substantial. Roughly 3,100 US Walmart stores now run some level of supply chain automation, and more than half of the company's ecommerce fulfillment volume flows through automated facilities. Ecommerce now represents more than 23% of Walmart's US sales mix, double what it was five years ago, and that growth is happening because the stores themselves have become the delivery network, not despite the existence of physical stores.
That distinction matters for anyone trying to understand why Walmart's delivery speeds keep improving even as its ecommerce volume grows. A dense network of automated, store-based fulfillment nodes scales differently than a smaller number of dedicated distribution centers, and it's part of why Walmart Marketplace's fulfillment services penetration has climbed as fast as it has, since sellers routing through Walmart Fulfillment Services are tapping directly into this same store-based network.
The $2.9 Billion Tariff Refund Is Funding Real Price Cuts
Walmart confirmed it has received “substantially all” of the $2.9 billion in IEEPA tariff refunds it was eligible for, the largest refund reported by any US company so far, roughly three times the size of Target's $994 million and well ahead of Home Depot's $730 million and TJX's $331 million. Rainey was direct about where the money is going: toward customer experience and price leadership, with priority investment in grocery and general merchandise.
That's not a future promise. Walmart already cut prices in July on thousands of products, including beef, Coca-Cola, and laundry detergent, and the tariff refund is what's funding the continuation of that push into the back half of the year. Rainey said the company is investing in price “because customers need it and because it is expected to drive market share gains over time.”
Why Q3 Guidance Looks Weaker Than It Actually Is
Here's a detail worth understanding before you read too much into Walmart's Q3 numbers when they land in November. Rainey flagged directly that the tariff refund created “some idiosyncrasies” in how this quarter's results compare to next quarter's guidance. A large share of the refund got invested into pricing at the very end of Q2, meaning the full-quarter cost of that investment hits Q3 numbers much harder than it hit Q2's.
His specific guidance: “We would encourage you to look at our operating income growth for Q2 and Q3 together to assess the underlying performance of the business.” Averaged across both quarters, operating income growth runs around 10% per quarter, a meaningfully stronger picture than either quarter looks at in isolation. Despite that timing distortion, Walmart still raised its full-year guidance, with adjusted EPS moving to $2.80 to $2.87 from $2.75 to $2.85, and net sales growth guidance rising to a 4% to 5% range from the prior 3.5% to 4.5%.
Analysts read the underlying business as healthy despite the headline deceleration. Jefferies called it a “position of strength,” pointing to “transaction growth, broad-based share gains, and continued strength across eCommerce, advertising, marketplace, and membership.” TD Cowen said it remains “encouraged by Walmart's ability to gain share and grow profits faster than sales.”
What This Means for Your Q4 Planning
If you sell in grocery, household staples, or general merchandise categories that overlap with what Walmart just discounted, treat this as a direct signal about the price environment you're competing against heading into the holidays. A price cut funded by a one-time refund windfall isn't something you can match dollar-for-dollar out of your own operating margin, but it does set the reference price point shoppers carry into every other channel they browse, including Amazon and your own storefront.
If you sell through Walmart Marketplace and haven't fully evaluated Walmart Fulfillment Services, the 80%-of-orders stat is a useful data point for understanding just how central the store network has become to Walmart's actual delivery capability. A fulfillment system this deeply integrated into physical retail infrastructure is going to keep getting faster as automation expands across those 3,100-plus stores, which raises the bar for what “competitive delivery speed” means on that platform over the next few quarters, not just this one.
