Who Is Buying Costco? Hedge Fund Activity in 2026

Costco Wholesale is a hedge fund favorite that defies conventional valuation logic. Trading at a premium multiple that would make most value investors cringe, COST commands its valuation through one of the most loyal customer bases in retail, a membership model that generates near-pure-profit recurring revenue, and a management team obsessed with passing value to customers. For institutional investors, Costco represents the gold standard of retail execution.

Let's examine which hedge funds are buying, holding, and selling Costco based on the latest 13F filings.

Costco at a Glance

Costco's 93% membership renewal rate is one of the most remarkable customer loyalty metrics in all of business. It means that once someone joins Costco, they almost never leave — creating a predictable, recurring revenue stream that institutional investors find irresistible.

Who's Buying Costco in 2026?

Based on Q4 2025 13F filings, several major hedge funds have been adding to their COST positions:

1. Bridgewater Associates

Bridgewater increased its Costco position by 38% in Q4 2025, now holding approximately $2.4 billion. The macro fund views Costco as one of the best defensive consumer holdings — a company that actually gains market share during economic downturns as consumers seek value.

2. Capital Research Global Investors

Capital Research added approximately 6 million shares of COST, making it one of the fund's top consumer staples holdings. The long-term investor sees Costco's international expansion (particularly in Asia) as a multi-decade growth opportunity.

3. Viking Global Investors (Andreas Halvorsen)

Viking Global initiated a new $2.1 billion position in Costco during Q4 2025. Halvorsen's team views COST as a rare retailer with pricing power, customer loyalty, and management quality that justifies its premium valuation.

4. Citadel Advisors (Ken Griffin)

Citadel added approximately $1.7 billion in COST shares, with the fund recognizing Costco's defensive characteristics and its ability to generate strong comparable store sales growth.

5. D.E. Shaw & Co.

D.E. Shaw boosted its Costco exposure by roughly 22%, now holding approximately $1.9 billion. The quant fund's models favor COST's earnings consistency and the predictability of its membership-driven revenue.

6. Millennium Management (Israel Englander)

Millennium increased its COST holdings by approximately 18%, with multiple pods attracted to the stock's low-beta profile and reliable earnings delivery.

Who's Reducing Costco?

1. Renaissance Technologies

Renaissance trimmed its COST position by approximately 20% in Q4 2025, with models possibly flagging the stock's elevated valuation relative to historical norms.

2. Two Sigma Investments

Two Sigma modestly reduced its Costco stake by roughly 12%, potentially rotating toward names with stronger near-term momentum.

Why Hedge Funds Like Costco

1. The Membership Model Costco generates approximately $5 billion in annual membership fees — revenue that drops almost entirely to the bottom line at near-100% margins. This predictable, recurring income stream effectively funds the company's operations, allowing Costco to sell products at razor-thin margins and still deliver strong profitability.

2. Counter-Cyclical Strength Costco is one of the few retailers that performs better during economic downturns. When consumers tighten budgets, they shift spending to value-oriented options — exactly what Costco offers. This counter-cyclical characteristic makes COST an ideal portfolio hedge for institutional investors.

3. Customer Fanaticism Costco's customers are not just loyal — they're fanatical. The 93% renewal rate, growing membership base, and enthusiastic customer culture create a competitive moat that no other retailer has replicated. The Kirkland Signature private-label brand generates over $70 billion in annual sales, rivaling the revenue of entire CPG companies.

4. International Expansion Costco operates approximately 900 warehouses globally, with significant growth potential in Asia (Japan, South Korea, China), Europe, and Australia. Each new warehouse generates strong returns on capital, and the international business is growing faster than the US segment. Hedge funds see a long runway of global store openings ahead.

5. E-Commerce Growth While Costco is primarily a brick-and-mortar retailer, its e-commerce business has been growing at 20%+ annually. Same-day delivery through Instacart, online-only products, and an expanding digital grocery offering are adding a new growth dimension to the traditional warehouse model.

Recent Institutional Moves

The 13F data for Costco in early 2026 shows strong and consistent institutional buying:

• New positions opened: Approximately 250 funds initiated new COST positions in Q4 2025
• Positions increased: Roughly 690 funds added to existing holdings
• Positions reduced: About 310 funds trimmed their stakes
• Positions exited: Approximately 95 funds closed their Costco positions entirely

The most notable trend is defensive rotation into Costco during a period of economic uncertainty. When hedge funds worry about recession risk, Costco is consistently one of the first stocks they add — its combination of value pricing, necessity-oriented products, and membership stickiness provides a floor under the business.

Frequently Asked Questions

How many hedge funds own Costco?

As of Q4 2025, approximately 4,400 institutional investors report holding Costco in their 13F filings. Among hedge funds specifically, roughly 870+ hold COST positions. The stock's broad institutional ownership reflects its status as a consensus quality holding across multiple investment styles.

Why does Costco trade at such a high P/E ratio?

Costco consistently trades at 35-50x forward earnings, well above the market average. Hedge funds justify this premium because of the membership model (predictable recurring revenue), counter-cyclical resilience, long-term growth runway, and exceptional management quality. The premium reflects Costco's status as a "forever compounding" business.

Is Costco a defensive stock?

Yes, Costco is widely considered one of the most defensive stocks in the consumer sector. Its value-oriented business model means customers trade down to Costco during recessions rather than away from it. During the 2008 financial crisis and the 2020 pandemic, Costco's comparable store sales actually accelerated — a rare characteristic among retailers.

Does the membership fee increase affect investor sentiment?

Membership fee increases are actually viewed positively by hedge funds. When Costco raises its annual fee (approximately every 5-6 years), the 93% renewal rate demonstrates that customers find the value proposition compelling enough to absorb the increase. Each fee hike flows almost directly to the bottom line, providing a significant earnings boost.
