NASDAQ: COSTCostco Wholesale Corporation is the third-largest retailer in the world and the undisputed king of the warehouse club model. Founded in 1983 in Seattle, Washington (merging with the original Price Club in 1993), the company operates a deceptively simple business: charge people an annual fee to enter a no-frills warehouse, then sell them a curated selection of goods at razor-thin margins. It shouldn't work as well as it does. But Costco has turned this formula into one of the most admired — and most imitated — business models in modern retail, generating $269.9 billion in net sales in fiscal year 2025 with a net income of $8.1 billion.
As of early 2026, Costco operates approximately 900+ warehouse locations across 14 countries, including the United States, Canada, Mexico, the United Kingdom, Japan, South Korea, Australia, Taiwan, China, Spain, France, and Iceland. The company employs over 300,000 workers worldwide. Its warehouses are deliberately spartan — concrete floors, industrial shelving, goods stacked on pallets — because every dollar not spent on aesthetics is a dollar returned to the member through lower prices. This ethos permeates everything Costco does.
What makes Costco genuinely unusual in the retail landscape is its relationship with its customers. Members don't just shop at Costco — they believe in Costco. The company commands a fervent, almost religious loyalty that manifests in packed parking lots on weekends, viral TikTok hauls, a 440,000+ member subreddit (r/Costco), and the cultural phenomenon of the "$1.50 hot dog combo" — a price that hasn't changed since 1985 and that co-founder Jim Sinegal famously swore would never increase. The hot dog is a loss leader, a meme, and a brand promise all at once.
Costco is not just a retailer. It's a subscription business disguised as a warehouse, a private-label empire hiding behind national brands, and increasingly, a financial services platform selling everything from auto insurance to gold bullion. Understanding how all these pieces fit together is key to understanding why COST trades at a P/E ratio that would make most consumer staples investors faint.
Costco's business model is elegantly counterintuitive. The company makes almost no money selling you stuff. Its merchandise margins hover around 10–11%, with a hard internal cap of roughly 14–15% markup on any item — a policy set by co-founder Jim Sinegal and maintained to this day. For comparison, traditional grocers operate at 25–30% gross margins, and specialty retailers can push 50%+. Costco is voluntarily leaving billions in margin on the table.
So where does the profit come from? Membership fees. The annual dues — $65 for a Gold Star membership, $130 for Executive — generate approximately $4.8 billion per year in high-margin revenue. This membership income effectively is Costco's profit. In fiscal 2025, membership fee income grew 14% year-over-year, driven by the September 2024 fee increase (the first in seven years, raising Gold Star from $60 to $65 and Executive from $120 to $130) and continued growth in executive-tier upgrades.
The genius of this model is the flywheel it creates: low prices drive membership growth → membership fees fund operations → operational efficiency enables even lower prices → which drives more membership growth. It's a virtuous cycle that competitors have struggled to replicate. Sam's Club (Walmart) and BJ's Wholesale operate similar models but have never achieved Costco's renewal rates or member loyalty.
A 92.3% renewal rate in the US and Canada is not just good — it's extraordinary. For context, Netflix's churn rate implies roughly 90% annual retention in mature markets, and that's considered excellent for a streaming service. Costco achieves Netflix-level stickiness for a physical retail membership. The worldwide rate of 89.8% is slightly lower due to newer international markets where the Costco habit hasn't fully entrenched.
The September 2024 fee increase was a critical test. After seven years without a hike, there was genuine investor concern about whether the increase would dent renewals. The results are in: renewal rates held firm. Members barely blinked. Bernstein analysts named Costco alongside Amazon and Walmart as "best positioned to ride a macro storm" due to the "membership lock-in" effect. When nine out of ten customers automatically renew, you don't have a retail business — you have a recurring revenue engine.
A typical Costco warehouse carries roughly 3,700–4,000 SKUs (stock-keeping units). A Walmart Supercenter carries 120,000+. A typical grocery store carries 30,000–50,000. This radical simplification is not a limitation — it's the strategy. By offering fewer products, Costco can negotiate enormous volume discounts with suppliers, move inventory faster, reduce waste, and keep operational complexity low. Every item on the warehouse floor has earned its place through a brutal selection process. If it doesn't turn fast enough, it gets cut.
This limited selection also creates the famous "treasure hunt" experience — the sense that you never know what you'll find when you walk through those warehouse doors. Costco regularly rotates seasonal and specialty items, creating urgency ("if I don't buy it now, it might be gone next week"). This drives impulse purchases and repeat visits that far exceed what the typical grocery run would generate. You came for paper towels. You left with a kayak, a case of wine, and a 5-pound bag of pistachios.
Kirkland Signature is Costco's private-label brand, and it is, by any measure, one of the most successful consumer brands in the world. Named after the city of Kirkland, Washington (where Costco was headquartered until 1996), the brand launched in 1995 as a consolidation of Costco's various house labels into a single, unified brand. That decision — putting everything under one name — was radical at the time and has proven to be a masterstroke.
Most private-label brands position themselves as "good enough" budget alternatives to name brands. Kirkland Signature flipped this paradigm entirely. Costco's strategy is to make Kirkland products match or exceed the quality of the leading national brand in any category — and then price them 20–40% lower. This isn't aspirational marketing; it's the actual operating mandate.
The results speak for themselves. Kirkland Signature vodka is widely rumored to be produced by the same distillery as Grey Goose (a claim neither company confirms). Kirkland batteries consistently match Duracell in independent testing. Kirkland olive oil has won international competitions. Kirkland diapers rival Huggies. The brand has become so trusted that many Costco members default to Kirkland without even comparing — the opposite of how consumers traditionally interact with store brands.
Costco's approach to Kirkland production is uniquely sophisticated. Rather than operating its own manufacturing at scale, Costco partners with leading national brand manufacturers to produce Kirkland products. In many cases, a Kirkland item rolls off the same production line as the name-brand equivalent, with only the label different. This arrangement works because of Costco's enormous volume guarantees — manufacturers accept lower margins per unit in exchange for massive, predictable orders.
This creates an interesting competitive dynamic. National brands simultaneously compete with and produce for Kirkland. Procter & Gamble, Kimberly-Clark, Starbucks (which roasts Kirkland coffee), and dozens of other major manufacturers have Kirkland relationships. For the manufacturer, refusing to work with Kirkland means losing Costco shelf space entirely — and no consumer goods company wants to be absent from 900+ warehouses serving 77 million households.
While Kirkland spans everything from clothing to cookware, certain product lines have achieved cult status:
Costco's revenue is overwhelmingly driven by merchandise sales — approximately 98% of total revenue comes from selling goods in its warehouses and online. The remaining ~2% comes from membership fees. But that 2% is deceptively important: membership fees carry near-100% margins and effectively represent the company's entire profit pool. Strip out membership income, and Costco's merchandise operations run at roughly breakeven — by design.
| Metric | FY2024 | FY2025 | Change |
|---|---|---|---|
| Net Sales | ~$254B | $269.9B | +6.3% |
| Net Income | ~$7.4B | $8.1B | +9.5% |
| Membership Fee Income | ~$4.2B | $4.8B | +14% |
| Comparable Sales Growth | — | ~6–7% | Strong |
| Warehouses (end of period) | ~882 | ~914 | +32 |
Costco's gross margin of approximately 12.5% is among the lowest in all of retail. This is intentional. The company's operating model is predicated on keeping prices as low as possible to maximize membership value. Management has repeatedly stated that they will never raise margins beyond the historical range — any efficiency gains or supplier concessions get passed directly to the member. This philosophy, inherited from co-founder Jim Sinegal, is treated as sacred by the current leadership.
The result is a business that looks anemic on a per-unit margin basis but generates enormous absolute profits through sheer volume. Costco's inventory turnover — how quickly it sells and replaces stock — is approximately 12x per year, roughly double the rate of traditional retailers. Money comes in, goods go out, and the cycle repeats at extraordinary speed.
In the summer of 2023, Costco began selling one-ounce 24-karat gold bars through its website. What started as a seemingly niche experiment quickly became one of the most talked-about product launches in Costco's history — and a cultural moment that perfectly encapsulates why Costco is Costco.
The gold bars sell out within hours of being listed. According to a widely-cited Wells Fargo analysis from early 2024, Costco was moving an estimated $100 million to $200 million worth of gold bars per month. That's $1–2 billion in annualized gold sales from a wholesale club better known for rotisserie chickens and bulk toilet paper. By late 2024, Costco had expanded into silver coins as well, and bullion remained a top-selling category on the company's e-commerce platform through 2025.
The appeal is straightforward: Costco sells gold bars at a slim 2% premium over the spot price of gold — dramatically lower than the typical 5–10% premiums charged by traditional bullion dealers. For a product where price transparency is total (gold spot prices are public knowledge), Costco's value proposition is immediately obvious. Add the company's famously generous return policy and the trust that comes with the Costco brand, and you have a gold-buying experience that feels nothing like visiting a coin shop or navigating a bullion website.
The gold bar phenomenon reveals something interesting about Costco's customer base. These aren't traditional gold bugs or doomsday preppers — they're upper-middle-class suburbanites who already trust Costco with their groceries, gas, and pharmacy needs. Costco has effectively democratized gold ownership by removing the friction, uncertainty, and sketchy dealer dynamics that have traditionally kept mainstream consumers out of the bullion market.
Reddit threads on r/Costco and r/investing are filled with members trading tips on when new gold drops happen, which warehouses have stock, and strategies for getting through the checkout process before bars sell out. The frenzy mirrors sneaker drops and limited-edition product launches more than traditional commodity purchasing.
There is something deeply absurd and deeply American about a company that refuses to raise the price of a hot dog combo above $1.50 while simultaneously moving hundreds of millions of dollars in gold bullion per month. This juxtaposition — the mundane and the extraordinary coexisting under the same warehouse roof — is the essence of the Costco brand. It's a place where you can buy a year's supply of paper towels, a casket, a $2,700 gold bar, and a $4.99 rotisserie chicken in a single trip. No other retailer on Earth offers this range.
Costco is in the midst of its most aggressive expansion phase in decades. In fiscal year 2025, the company opened 27 new warehouses, bringing its global total to approximately 914 locations. For fiscal year 2026, the company has announced plans to open 35 new warehouses (of which 5 are relocations of existing stores), with a capital expenditure budget of approximately $6.5 billion. At this pace, Costco will cross the 1,000-warehouse milestone by 2028.
Approximately 10 of the 2025 warehouse openings were international, spread across Canada, Mexico, Europe, and Asia. Costco's international expansion strategy is methodical and deliberate — the company enters new markets slowly, builds brand awareness through a handful of locations, and then accelerates once the membership model proves it can translate culturally. Japan and South Korea have been particularly strong performers, with warehouse productivity (sales per location) that rivals or exceeds US averages.
The China market represents both the biggest opportunity and the biggest unknown. Costco's first mainland China warehouse opened in Shanghai in 2019 to scenes of chaotic overcrowding — it had to close early on opening day due to safety concerns from the crush of shoppers. The company has since opened additional Chinese locations and is reportedly planning further expansion, though the geopolitical and regulatory environment adds layers of complexity that don't exist in Costco's other markets.
Despite having nearly 600 US warehouses, Costco management has consistently indicated that the domestic market is not yet saturated. New US openings in 2025 included locations in Brentwood, California; Highland, California; Prosper, Texas; Weatherford, Texas; Genesee County, Michigan; and Sharon, Massachusetts. The company tends to cluster new openings in high-growth sunbelt markets and affluent suburban areas where the demographic profile aligns with the typical Costco member: household income above $100,000, homeowner, family-oriented.
Costco's stock is, depending on whom you ask, either one of the highest-quality compounders in the market or an absurdly overvalued consumer staples stock trading at a tech multiple. At a forward P/E ratio of approximately 51x, COST trades at more than double the S&P 500 average and roughly 3x the valuation of peers like Walmart (WMT) or Kroger (KR). In 2025, the market cap declined modestly from approximately $407 billion in January to $383 billion by December — a ~6% pullback that underperformed the broader market.
The bull argument for the premium is simple: Costco deserves it. The 92%+ renewal rate creates an annuity-like revenue stream. The low-margin model is a competitive moat that no one can replicate. Kirkland Signature is one of the world's great brands. The company has decades of runway for warehouse expansion. And management is disciplined, shareholder-friendly, and obsessively focused on the member value proposition. This is a "sleep at night" stock for long-term investors.
In late January 2025, Costco faced its most significant labor confrontation in recent memory. Approximately 18,000 Teamsters-represented workers authorized a national strike after contract negotiations stalled. The Teamsters accused Costco of "illegal and reckless behavior," including ejecting union representatives from stores, preventing employees from wearing Teamster buttons, and changing locks on union bulletin boards inside warehouses.
The standoff was resolved on February 1, 2025, when Costco and the Teamsters reached a tentative agreement, narrowly averting a strike. As part of the resolution, Costco raised pay for most workers above $30 per hour, reinforcing its reputation as a relatively high-paying employer in the retail sector. However, the Teamsters conflict revealed tensions beneath Costco's employee-friendly reputation. A separate complaint from Teamsters Local 174 alleged that Costco had withheld pay from fleet drivers in Washington state — a claim that remains in dispute.
In January 2025, amid a wave of corporations abandoning or scaling back Diversity, Equity, and Inclusion (DEI) programs under political pressure from the incoming Trump administration, Costco's board of directors took a strikingly different path. The board unanimously recommended that shareholders vote against an anti-DEI proposal, and at the subsequent shareholder meeting, the proposal was defeated by an overwhelming margin. Costco's leadership publicly defended its DEI practices as integral to its business success.
This positioned Costco as one of the few major corporations willing to publicly stand behind DEI in a hostile political environment. The decision drew both praise and backlash — conservative media outlets like Fox Business ran critical coverage linking the DEI stance to the Teamsters dispute, while progressive commentators and many Costco members lauded the company's stance. The net effect on membership or sales appears negligible, though the episode reinforced Costco's image as a company that charts its own course regardless of political winds.
In 2024, Costco rolled out barcode scanners at warehouse entrances, requiring members to scan their physical or digital membership card's QR code to enter. This replaced the previous honor-system approach of simply flashing a card at the door. The crackdown was aimed at preventing membership sharing — non-members using a friend's or family member's card to shop. While financially rational (every non-paying shopper is a leak in the membership model), the change generated significant consumer pushback, particularly on social media, where it was perceived as hostile and trust-eroding.
Costco has faced periodic scrutiny over its supply chain practices. A notable controversy involved Chaokoh coconut milk — Costco stopped purchasing from the brand after reports emerged that the production process involved monkey labor and animal abuse in Thai coconut harvesting. The company's shrimp sourcing has also drawn attention, with advocacy groups flagging labor conditions in Southeast Asian seafood supply chains. Costco has responded by expanding its supplier auditing programs and publishing annual sustainability reports, though critics argue the company's scale makes full supply chain transparency difficult to achieve.
While not a controversy in the traditional sense, Costco's commitment to maintaining the $1.50 hot dog and soda combo — unchanged since 1985 — has become a cultural flashpoint. Co-founder Jim Sinegal famously told then-CEO Craig Jelinek: "If you raise the [price of the] effing hot dog, I will kill you." The hot dog is a loss leader that generates goodwill far exceeding its cost. But in an era of persistent food inflation, the commitment is increasingly viewed as either an admirable act of brand integrity or an unsustainable marketing gimmick. For now, the $1.50 hot dog endures.
âš ï¸ Sentiment data is estimated based on aggregated community discussions and is not scientifically sampled. It reflects online conversation trends, not a representative survey.
The Costco subreddit is one of the most active brand-specific communities on Reddit, and the tone is overwhelmingly positive — bordering on devotional. Members share haul photos, product reviews, deals, and warehouse-specific tips with a level of enthusiasm typically reserved for hobbyist communities. The phrase "Costco is a cult" is used self-awarely and affectionately. A representative post titled "Costco is a cult. Change my mind" generated hundreds of comments, most of which essentially agreed — and were fine with it. As one commenter put it: "From a consumer perspective, they've earned that reputation."
The subreddit does surface legitimate complaints: inconsistent stock (items disappearing without warning), crowded parking lots, the checkout line experience, and the membership card scanning crackdown. But the overall vibe is that of a fan community rather than a consumer complaint forum. This is remarkable for a retail store.
Dissenting voices exist but are notably outnumbered. Posts like "I hate Costco" in contrarian subreddits tend to cite the overwhelming crowds, the absurdity of buying in bulk for a small household, the sensory overload of the warehouse environment, and the cultish behavior of Costco evangelists. These posts are typically met with spirited defenses from Costco members. One common retort: "They have an excellent return policy. The company actually gives a s**t about something aside from just squeezing its members for the highest profit. It has a cult following for a reason."
Financial Reddit is broadly bullish on Costco as a business but conflicted on Costco as a stock. The most common sentiment: "Incredible company, but at 50x earnings, where's the upside?" Many retail investors report owning COST as a long-term "set it and forget it" holding, while others describe it as perpetually too expensive to initiate a position. The Teamsters scare in January 2025 generated temporary concern, but the resolution reinforced confidence in Costco's ability to navigate labor challenges.
A Fortune article titled "The cult of Costco: How one of America's biggest retailers methodically turns casual shoppers into fanatics" was shared on r/business and generated a telling discussion. The top-voted comment noted: "The article doesn't justify the tagline to me — it describes what Costco does and why, and it all seems pretty flattering. It doesn't paint the picture of a cult so much as an effective, mutually beneficial business that people respond to enthusiastically." This captures the broader public sentiment: Costco's "cult" status is earned through genuine value delivery, not manipulation or hype.

Costco enters 2026 in a position of extraordinary operational strength. The membership model is firing on all cylinders — renewal rates are at record highs despite the fee increase, Kirkland Signature continues to gain share, new warehouses are opening at an accelerating pace, and the company's brand equity is arguably the strongest in all of retail. The Teamsters confrontation was resolved without a strike. The DEI stance was absorbed without meaningful backlash. Gold bars are selling by the hundreds of millions. The $1.50 hot dog endures.
The challenge for investors is entirely about price versus value. At 51x forward earnings, COST is priced as if it's a high-growth tech company rather than a warehouse retailer growing revenue at mid-single digits. The stock declined ~6% in 2025 even as the business performed well, suggesting that the market may be reaching the limits of what it's willing to pay for Costco's admittedly exceptional quality. A meaningful earnings miss, a crack in renewal rates, or a broader market rotation away from premium-valuation defensives could trigger a 15–25% drawdown that would still leave the stock "expensive" by traditional metrics.
And yet — bears have been wrong on Costco for decades. Every time the stock looked "too expensive," it kept compounding. The business model is genuinely superior, the management is disciplined, and the cultural moat (440,000 Reddit evangelists, TikTok haul videos, the hot dog meme) is unlike anything else in retail. Costco isn't just selling goods at low margins. It's selling belonging — the feeling that you're part of a smart-shopper tribe that has figured out a better way to buy things. That emotional connection, layered on top of genuine economic value, is extraordinarily difficult to disrupt.
Costco might be the most beloved company in America, and they've earned it. The membership model is borderline genius — you're paying $65/year for the privilege of shopping there, and somehow it feels like a steal. Kirkland Signature is the most underrated brand in retail; they're basically selling name-brand quality at store-brand prices across everything from vodka to golf balls. The gold bars went viral and somehow became a legitimate investment vehicle for regular people. Here's what impresses us most: Costco treats its employees well (starting wages well above minimum, real benefits) and still delivers consistent earnings growth. In an era where every retailer is cutting corners, Costco proves you can do right by workers and shareholders simultaneously. The only knock? International expansion is slow, and the e-commerce experience still feels like an afterthought compared to Amazon.
