What is Costco?
Costco is a membership warehouse retailer that sells a limited assortment of high-volume merchandise at low markups. It operates warehouses, e-commerce sites, gas stations, pharmacies, optical centers, food courts, travel services, and the Kirkland Signature private label.
Costco's model is built around paid membership, treasure-hunt merchandising, high inventory turns, and a relatively narrow SKU count compared with traditional mass retailers. Fiscal 2025 net sales were $269.9 billion, net income was $8.1 billion, and membership fee revenue was $5.4 billion.
The company operates globally but remains anchored in North America, with warehouses in the United States, Canada, Mexico, Japan, the United Kingdom, Korea, Australia, Taiwan, China, Spain, France, Iceland, New Zealand, and Sweden. Its scale comes from warehouse productivity, renewal rates, private-label penetration, fuel traffic, and a procurement machine that turns low gross margins into high member value.
Costco's differentiation is that membership fees carry much of the profit engine while merchandise pricing is kept tight. For vendors, that means a buyer with huge volume potential, but with strict cost, quality, logistics, and compliance expectations.

How does Costco make money?
Costco makes money from merchandise sales and recurring membership fees, with membership economics supporting low merchandise markups.
Costco has two core revenue lines: net sales from merchandise and services, and membership fees. In fiscal 2025, net sales were $269.9 billion and membership fee revenue was $5.4 billion. U.S. Gold Star and Business memberships are priced at $65 per year, while Executive Membership is priced at $130 per year and includes a 2% annual reward on eligible purchases subject to program rules.
The warehouse model is designed for high volume and low markup. Costco keeps a limited assortment, buys in bulk, moves inventory quickly, and uses paid membership to reinforce loyalty and economics. Ancillary businesses such as gas, pharmacy, optical, travel, and food court deepen member frequency even when margins are thin.
Growth comes from new warehouses, membership growth and renewal, Executive upgrades, comparable sales, e-commerce, private-label mix, and international expansion. Vendor success depends on landed cost, supply reliability, packaging, compliance, and the ability to support massive volume if a product wins placement.

Costco is a mature public company, not a VC-backed company: it trades on Nasdaq as COST, had a market cap around $435 billion in June 2026, and funds growth through operating cash flow, public debt/equity access, and membership economics.
Costco's capital history begins with the Price Club and Costco predecessors, the 1985 public listing of Price Club, the 1993 merger with Costco, and decades of warehouse expansion. The modern capital story is not startup rounds; it is public-market access, strong operating cash flow, debt capacity, dividends, special dividends, and long-lived real estate and inventory investment.
In fiscal 2025, Costco produced $269.9 billion of net sales, $5.4 billion of membership fees, and $8.1 billion of net income. That profit model gives the company substantial internal funding capacity for new warehouses, supply-chain investments, technology, wages, and shareholder returns.
Seller signal: Costco has enormous buying power, but it is one of the most demanding retail customers. Vendors need to prove cost advantage, supply resilience, packaging fit, quality, compliance, and member value. Technology sellers should map to warehouse productivity, data, e-commerce, membership, payments, logistics, and inventory visibility.
