Sam's Club added 1 million members in 9 months, with e-commerce accounting for 55%, relying on forward warehouses and centralized procurement to restructure retail, but quality control faces tests.

When Sam's Club took a full 21 years to accumulate its first 1 million members from scratch, yet needed an incredible 9 months to add its third million, the outside world's first instinct is often to attribute this to the warehouse membership format catering to middle-class families' dual demand for high quality and high cost-effectiveness. However, once you combine Walmart China's hardcore second-quarter scorecard of net sales reaching as high as $7 billion, a year-over-year surge of 20.7%, and pull your view down to the underlying data showing that e-commerce net sales accounted for more than 55% in one fell swoop, you will find that this so-called Sam's miracle is by no means the old-style growth of traditional hypermarkets piling up gains by opening stores, but an omnichannel digital blitzkrieg in which large warehouse stores serve as the mental totem and the capillary network of front warehouses serves as the fulfillment harvesting machine.
Racing Against the Tide: Rebuilding the Trust Mechanism, with Membership Fees Reduced to a Money-Saving Tool
For a long period in the past, the traditional brick-and-mortar retail industry was shrouded in pessimism. Customer traffic in the hypermarket format was halved, a wave of store closures among traditional supermarkets followed one after another, and foreign retail giants either successively retreated from the Chinese market or transferred their operations in packaged deals. Yet Sam's raced against the tide with an extremely contrasting posture.
The deeper reason lies in the fact that Sam's fundamentally rebuilt the trust mechanism between product procurement and consumers. After the traditional hypermarket model of relying on slotting fees and listing fees charged to suppliers became comprehensively ineffective, Sam's relied on a global centralized procurement scale in the hundreds of billions to cut out all intermediate links, pressing selected SKUs down to highly attractive landed prices, and turning the annual membership fee of 260 yuan or even 680 yuan directly into a money-saving tool and a form of identity recognition.
A Deep Foundation: $300 Million in Registered Capital and a Nearly 3,000-Person Operating Team
Looking through to the top-level legal entity structure supporting the operation of this precision commercial machine, its strategic foundation built over more than two decades of deep cultivation in China is revealed in the underlying business registration archives as extremely solid. Tianyancha business registration data shows that, as Walmart's core investment hub in China, Walmart (China) Investment Co., Ltd. was established in April 2003, with Liu Peng as its legal representative, registered capital as high as $326.6 million, and a business scope spanning the entire chain of food sales, internet sales, warehousing services, distribution, and market research.
In the annual report data accumulated by Tianyancha, the number of insured employees of this investment entity alone reached 2,903 in 2025, outlining an extremely large, multi-functional headquarters-spanning heavy-duty operating team.
The foundation of more than $300 million in registered capital and an investment management structure of nearly 3,000 people have provided the most solid resource backing for Sam's frenzied digital leap in recent years.
A more intriguing variable lies in the historic breakthrough of e-commerce sales accounting for as high as 55%.
Integrated Warehouse and Store: Front Warehouses Shatter Physical Limits and Harvest the Time Premium
The warehouse membership store format originally originated in the highway civilization of the United States, where land is vast and population sparse, and families rely on weekend drives for centralized bulk shopping. But Sam's achieved a record-breaking pace of adding a million members in 9 months in China, with its core tactic being to completely shatter the physical limitation of driving two hours to the suburbs on weekends to haul goods. By relying on hundreds of rapid-delivery cloud warehouses (front warehouses) deeply deployed within a three-kilometer radius of middle-class communities in core cities, Sam's turned physical stores occupying tens of thousands of square meters with long shopping routes into super display centers responsible for category endorsement, tasting experiences, and member sedimentation;
while the truly high-frequency repurchase items such as meat, poultry, eggs, milk, and Swiss rolls, among other hit products, continuously flowed onto middle-class dining tables through rapid-delivery front warehouses with one-hour delivery.
This approach of integrating warehouses and stores, using front warehouses to harvest repeat purchases, precisely captured the extremely scarce time premium of today's high-net-worth urban families. When Sam's e-commerce penetration rate crossed the critical threshold of 50%, it had already detached itself in competitive terms from pure offline grappling with brick-and-mortar rivals such as Hema and Costco, and directly launched a dimensional strike into the heartland of traditional fresh food e-commerce. Relying on the extremely high turnover rate of physical stores and the absolute cost advantage formed by global centralized procurement, Sam's front warehouses demonstrate a profit elasticity in average order value and shrinkage control that traditional pure e-commerce platforms cannot match.
Hidden Reefs: The Supply Chain Stretched to Its Limits Under Membership Expansion
However, behind the myth of wild growth speed also hang hidden reefs.
The membership scale expanding passively by millions in just 9 months means the customer base is inevitably spilling over from the early picky, loyal, high-net-worth middle class rapidly toward mass consumer groups that are more price-sensitive and less tolerant of quality failures. As the membership base expands exponentially, how to maintain the scarcity of product selection and the high standards of quality control will become the biggest interrogation facing Sam's supply chain.
Recent occasional complaints on social media about reseller markups, near-expiry controversies, and reduced specifications in product selection are essentially warning signals after the supply chain has been stretched to its limit by instantaneous high-concurrency demand.
The Cold Fact: Brick-and-Mortar Retail Never Died, Only Inefficient Intermediaries Are Out
This high growth driven jointly by physical giants and digital rapid delivery sends the entire retail market a cold fact: brick-and-mortar retail has never died; what has died is only the inefficient intermediary that cannot provide consumers with certain value. When Walmart China has moved more than half of its turnover to the cloud, those conservatives guarding traditional shelves and waiting bitterly for customer traffic to return will eventually understand that only by welding the world's top-tier product power and the ultimate local instant delivery tightly together can they, in the deep-water zone of stock-market competition, achieve absolute control over the consumption mindset of middle-class families.
