Members pay an annual fee to shop a small assortment of bulk groceries, household goods, electronics, fuel and services at low markups. FY2026 revenue was $303.2B, net income was $9.23B, and the company had 150.4 million cardholders. The massive American retail juggernaut was founded in Seattle, Washington in 1983, completely revolutionizing global retail by operating as a massive, membership-only warehouse club that aggressively limits product markups to essentially zero.

Costco Wholesale Corporation and Walmart Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Costco Wholesale Corporation and Walmart Inc..

Costco Wholesale Corporation business model: Costco runs a membership warehouse club: shoppers pay an annual fee ($65 for Gold Star or Business, $130 for Executive in the U.S. and Canada since September 2024) to buy from a tightly edited assortment of roughly 4,000 items. Limited choice means huge volume per item, which gives Costco strong buying power with suppliers. Costco caps markups at about 14% on branded goods and 15% on Kirkland Signature, so merchandise earns thin margins and membership fees ($5.9B in FY2026) supply much of the profit. Gas stations, pharmacy, optical, hearing aids, tires and Costco Travel bring members back more often, and Kirkland Signature lets Costco set a quality and price benchmark against national brands.

Walmart Inc. business model: Most of Walmart's revenue comes from selling groceries, consumables, general merchandise, health and wellness products, and fuel through stores, clubs, and ecommerce. Walmart U.S. is the largest segment at roughly two-thirds of revenue, followed by Walmart International (including Walmex, Flipkart, Walmart Canada, and Walmart China) and Sam's Club U.S. Retail margins are thin, so Walmart has been building income streams on top of the store base: Walmart Connect and Flipkart advertising, Walmart+ and Sam's Club membership fees, third-party marketplace commissions, and Walmart Fulfillment Services for marketplace sellers. Stores double as pickup and delivery points, which lets Walmart fulfill a large share of online orders from existing inventory.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Costco Wholesale Corporation stack up against those of Walmart Inc..

Costco Wholesale Corporation competitive advantage: Costco's advantage is a loop that rivals find hard to copy: membership fees fund low prices, low prices drive renewal (92.3% in the U.S. and Canada in FY2026), and high volume on about 4,000 items earns better supplier terms. Markups capped near 14-15% build price trust, Kirkland Signature gives Costco its own quality benchmark, and high inventory turnover means the company often sells goods before paying suppliers. Above-average retail pay and promotion from within keep turnover low and warehouses productive. Sinegal's well-known refusal to raise the $1.50 hot dog combo price is the public symbol of that discipline.

Walmart Inc. competitive advantage: Walmart's edge is purchasing scale, a dense U.S. store network that doubles as a fulfillment network, frequent grocery trips, and first-party purchase data that supports its advertising business.

Future prospects matter as much as current results. The growth strategies below explain how Costco Wholesale Corporation and Walmart Inc. each plan to expand from here.

Costco Wholesale Corporation growth strategy: Costco grows mostly by itself rather than through acquisitions. It opened 28 warehouses in FY2026 (25 net new) and plans 33 in FY2027, while pushing members to upgrade to Executive, which raises fee income and spending per household. Digital is the fastest-growing channel: digitally enabled sales topped $33B in FY2026 with site and app traffic up about 30%. Costco also leans on ancillary businesses (gas, pharmacy, travel) that grew faster than the core in FY2026, and on supply-chain investments such as its Nebraska poultry complex and Costco Logistics for bulky items.

Walmart Inc. growth strategy: Walmart is pushing store-fulfilled delivery, marketplace assortment, advertising, and membership while keeping its price position. In Q2 FY27 it reported 23% global ecommerce growth, 38% global advertising growth, 17% higher membership fee revenue, and U.S. marketplace sales up 52%.

A closer look at the financial trajectory of Costco Wholesale Corporation and Walmart Inc. rounds out the comparison.

Costco Wholesale Corporation: Costco's revenue is almost entirely merchandise: FY2026 net sales were $297.2B and membership fees were $5.907B, together $303.2B. Fees are under 2% of revenue but carry nearly full margin, so they make up a large share of operating income. Net income rose 13.9% to $9.226B ($20.76 per diluted share) from $8.099B in FY2025. Operating cash flow was $15.8B, capital spending was about $6.4B, and management plans about $7.5B of capex in FY2027. Q4 FY2026 included a one-time $0.15 per share benefit from IEEPA tariff refunds. Costco's gross margin is about 11% of sales and SG&A about 9%, a narrow spread that works only because of scale and fast inventory turns. Costco Wholesale Corporation is an absolute colossus in global retail, boasting a staggering market valuation generally exceeding $350 billion.

Walmart Inc.: Walmart's FY2026 total revenues rose 4.7% to $713.2 billion and net income attributable to Walmart rose to $21.9 billion from $19.4 billion in FY2025.

Adjusted operating income growth of about 17% in constant currency included a benefit from roughly $2.9 billion in IEEPA tariff refunds, much of which Walmart said it reinvested in prices. Walmart raised its full-year sales and operating income growth guidance with the Q2 report. Walmart is the world's largest company by revenue and holds a massive market valuation often exceeding $400 billion to $500 billion.
