Costco sued the United States government.
Not metaphorically. In late November 2025, Costco’s legal team filed suit against the Trump administration to preserve its right to collect tariff refunds — and to block import duties from being collected while the Supreme Court deliberated on the legality of the “Liberation Day” tariff package. When the Supreme Court ruled against the tariffs on February 20, 2026, the Penn-Wharton Budget Model estimated that more than $175 billion in US tariff collections could be subject to refunds. Costco immediately joined roughly 2,000 importers in trade court trying to lock in their place in the refund line.
A grocery and warehouse company that files a Supreme Court tariff lawsuit is not a conventional investment narrative. But then, Costco has never been a conventional company.
The stock is up 17% year-to-date in 2026 — a remarkable achievement when the S&P 500 is down more than 3% over the same period. Approximately 81.4 million people paid to shop there. The quarterly dividend was just raised 13% to $1.47 per share. Next earnings: May 28, 2026 .
At approximately $1,000 per share and a forward P/E of 47x, the question for investors is whether Costco’s consistency justifies the extraordinary premium — or whether the market has already priced in the next three years of compounding.

How Costco Actually Makes Money: The Fee Machine
This is the most important thing most retail investors misunderstand about Costco.
Costco is not primarily a retailer. It is primarily a membership subscription business that happens to operate retail stores.
Here’s the economics. Costco operates on deliberately thin merchandise margins — it aims to sell products at roughly 11% above cost on average, a fraction of typical grocery margins of 25–30% and specialty retail margins above 50%. The company’s goal is to be the cheapest place its members can buy anything. But that cheapness costs money to operate — real estate, labour, logistics, technology. So where does the profit come from?
Membership fees.
In Q2 FY2026, membership fee revenue came in at $1.36 billion — up 13.6% year-over-year — on the back of the September 2024 fee increase (first in seven years), which took Basic membership from $65 to $65 in the US (actually $65 to $65 — the US Basic stayed at $65, with Executive going to $130 from $120). Membership fees carry near-100% operating margins . There are no cost-of-goods-sold items inside a membership fee. It’s almost entirely pure income.
Over the first 24 weeks of FY2026, total membership fees reached $2.68 billion . Against total revenue of $136.9 billion in that same period, membership fees represent less than 2% of revenue — but they fund the majority of Costco’s operating income.
This creates a specific structural advantage that no conventional retailer can replicate: Costco’s operating income is largely pre-collected and recession-resistant. When consumers trade down during economic stress, they trade down to Costco — a business where spending more actually saves you money. The membership already paid, spending more per visit is a rational response to rising prices elsewhere.
Renewal rates tell the loyalty story plainly: 92.3% US and Canada renewal rate in Q2 FY2026, and 89.7% worldwide (the worldwide rate slips slightly as newer digital sign-ups — who renew at marginally lower rates than in-warehouse sign-ups — become a larger share of the total). As of the end of Q2, Costco had 81.4 million total paid members and 145.9 million cardholders — up 5.2% and 5.1% year-over-year respectively.
The September 2024 fee increase — which was the first since 2017 — had no measurable negative impact on renewal rates. That’s the cleanest possible validation that members view Costco as a utility, not a discretionary luxury.
Q2 FY2026: What the Numbers Actually Said
On March 5, 2026, Costco reported its fiscal second quarter results. The headline: net income of $2.035 billion, or $4.58 per diluted share — up nearly 14% from $1.788 billion ($4.02/share) in Q2 FY2025. EPS beat the Street consensus of $4.55 by $0.03.
The secondary numbers that matter more:
Net sales: $68.24 billion — up 9.1% from $62.53 billion. This is $68 billion in merchandise sales in a single quarter. For context, Costco processes more revenue in one quarter than most Fortune 100 companies do in an entire year.
Comparable sales: +7.4% (adjusted for gas price deflation and FX). Excluding gas entirely, core comparable sales were +7.4%, with fresh foods, meat, and bakery leading the way. This is real volume and price lift — not inflation-padded.
Digitally-enabled comparable sales: +22.6% (or +21.7% adjusted for FX). This is the number that has analysts reconsidering what they thought Costco’s long-term model looks like. A 22% digital comp from a company known primarily for warehouse shopping signals that the “Costco Digital Wallet” and broader e-commerce push is working — not just supplementing the physical experience but creating a distinct growth channel.
Operating cash flow (first 24 weeks FY2026): $7.68 billion. Free cash generation that supports the CapEx programme (full-year FY2026 guidance: $6.5 billion) without requiring debt.
The one area of management caution: gas price deflation dragged headline comparable sales down. Costco’s gas stations — which CEO Ron Vachris once described as selling “a lot of gas” — are traffic drivers more than margin contributors, but deflated gas prices mechanically suppress the reported comp. The underlying business ex-gas was stronger than the headline suggested.
The Tariff Lawsuit: What It Means for Costco’s Business
About a third of Costco’s US sales come from imported goods. With approximately 4,000 SKUs in a typical Costco warehouse at any given time (compared to a supermarket’s 30,000+ SKUs), the company has more pricing power per category than conventional retailers — but tariffs on imported goods still create cost pressure across meaningful categories: electronics, textiles, food components, packaging materials.
Costco’s response to tariffs in Q2 was explicit: CEO Vachris pledged the company would return any recovered tariff charges to members through lower prices. He lowered prices on eggs, cheese, coffee, and select paper products. He committed to further price reductions on textiles, bedding, and cookware as specific tariffs rolled back. The positioning is deliberate: in a tariff environment, Costco becomes more competitive versus conventional retailers who have to pass costs through to maintain margins.
The Supreme Court’s February 20, 2026 ruling struck down the IEEPA tariff mechanism — creating legal ambiguity about refunds. Costco potentially stands to receive between $500 million and $2 billion in tariff refunds (analysts estimate a wide range because Costco’s import mix, USMCA eligibility, and tariff rates by category aren’t disclosed in detail). Trump immediately responded by shifting to a flat 15% global rate, and analysts remain uncertain whether the refunds will actually materialise through lower court decisions.
What’s less uncertain: Costco’s structural positioning in a tariff environment. The company’s Kirkland Signature private label — which gives it control over supply chains and margins independent of branded goods pricing — becomes more valuable as imported branded goods face tariff headwinds. The company’s global buying scale allows it to consolidate purchasing across geographies in ways that small retailers cannot, and to switch sourcing from high-tariff countries to lower-tariff alternatives more efficiently.
The broader shift toward stablecoin payments and digital settlement infrastructure reflects a consumer-payments evolution that Costco is participating in — the “Costco Digital Wallet” initiative is designed precisely to reduce friction in the checkout-to-settlement process, an area where digital payment innovation is rapidly changing the competitive landscape for large retailers.
The Gas Station Business: Traffic Driver, Not Profit Centre
The original BCR article on Costco specifically focused on whether gas prices would fuel high sales. This deserves a direct answer in 2026.
Costco operates gas stations at approximately 700 of its 924 US and international locations. An April 16, 2026 TipRanks headline was literally: “Costco Is ‘Selling a Lot of Gas,’ Analyst Says — But There’s a Catch.”
The catch is the same catch it’s always been: Costco gas stations are traffic drivers, not profit drivers.
Costco consistently prices gas 10–25 cents per gallon cheaper than nearby stations. This creates predictable member behaviour: members come to fill up the tank, and while they’re there, many walk inside and buy $200–$400 in merchandise. The gas station operates at near-zero or marginally positive margins. The $300 spend on rotisserie chicken, Kirkland olive oil, a 48-pack of paper towels, and a pair of athletic shoes — that’s where the economics work.
The implication for stock analysis: when gas prices are high, Costco’s comparable sales figures look better (because gas revenue is included in the same-store sales calculation), and traffic in the physical warehouse improves as members seek value. When gas prices are low — as in the recent deflation environment — comparable sales are mechanically suppressed even if the underlying merchandise business is accelerating. The Q2 FY26 story was specifically this: headline comps of 7.4% masked what was actually strong merchandise comp growth, because gas price deflation subtracted from the aggregate number.
What this means for Q3 (reporting May 28, 2026): gas prices have recovered somewhat in March and April. If that recovery continues, Q3 comps will look stronger than Q2 on a headline basis even without acceleration in the underlying business. Conversely, any energy market disruption (the West Asia conflict has already been flagged as a potential fuel cost volatility risk for H1 FY27) could complicate Q3 gas dynamics.
April 2026: March Sales Report and the Dividend Raise
Two specific data points in April 2026 were particularly telling.
April 8, 2026 — March Sales Report: Costco reported March net sales of $28.41 billion — up 11.3% year-over-year with total comparable sales up 9.4% and digitally-enabled comparable sales surging 23.3% . This was despite one fewer shopping day in March 2026 versus March 2025. Adjusting for the calendar effect, the underlying monthly sales acceleration was even stronger than the headline suggested.
An 11.3% net sales growth month is not what analysts expected from a “consumer under pressure” environment. It confirmed that Costco is one of the specific retailers where macro stress functions as a tailwind — not because shoppers are in distress but because they’re actively rationalising their spending toward higher-value options.
April 15, 2026 — Quarterly Dividend Raised 13%: Costco’s board raised the quarterly dividend from $1.30 to $1.47 per share , payable May 15, 2026. This is a 13.1% increase and continues the pattern of annual dividend growth that has made COST one of the most consistent dividend growers in the S&P 500. The annualised yield at $1,000/share is approximately 0.59% — not high in absolute terms, but the dividend growth rate matters more than the current yield for long-term holders.
Costco’s business model shares structural similarities with subscription-based digital platforms — pre-collected recurring revenue, high switching costs, and network effects that improve with scale. The same principle that makes stablecoin adoption sticky (users who integrate the payment method find it increasingly inconvenient to switch) applies to Costco memberships: once a household is organised around bulk buying and Kirkland Signature products, switching costs are real and habitual.

What Analysts Are Saying in April 2026
| Firm | Rating | Commentary |
|---|---|---|
| Bernstein | Buy | April 26, 2026: fresh Buy rating |
| Bank of America | Buy | April 15: “sticking to Buy” — dividend raise cited |
| Morgan Stanley | Overweight | Consistent; COST as defensive compounder |
| TIKR consensus | Buy | Mid-case $1,410 by FY2030 (Aug 31, 2030) |
| Seeking Alpha bears | Hold | “Compounding already priced in” at 47x forward P/E |
The analyst consensus average target of approximately $1,078 implies about 7–8% upside from the current price. That conservative number doesn’t mean analysts are bearish on the business — it means the business is well-understood and almost fully priced.
The honest assessment: when your 12-month target is only 7% above current price for one of the world’s highest-quality businesses, the question isn’t whether Costco is good — it’s whether being good at this valuation is still an attractive risk/reward versus other opportunities.
The Valuation Debate: What Exactly Are You Paying For at 47x Forward Earnings?
Costco trades at approximately 47x next-twelve-month earnings. The S&P 500’s average is around 20x. The highest-quality consumer staples companies trade at 25–30x. Costco is at nearly double the quality premium.
The justification offered by Costco bulls has two parts.
Part One: Membership fee income has near-100% margins and grows predictably. With 81.4 million paid members and an average annual fee of approximately $65–$130, Costco collects approximately $5–7 billion per year in near-pure-profit income that doesn’t require any additional capital to generate. This revenue is more like a software subscription than a retail sale — it arrives before any product is moved, it renews at 92%+ in mature markets, and it scales as the member base grows. Investors are paying a SaaS-company multiple on a business with SaaS-level recurring fee economics inside a traditional retail wrapper.
Part Two: The digital acceleration changes the terminal value. The +22.6% digital comparable sales in Q2 isn’t just a pandemic-era holdover. Costco’s “Costco Digital Wallet,” its same-day delivery expansion, its “Costco Next” curated third-party marketplace, and its broader goal of making digital sales 15–20% of total revenue by end of the decade represent a meaningful expansion of the total addressable market. A physical warehouse can serve members within driving distance. Digital infrastructure serves members everywhere — including international markets where physical warehouse growth is expensive and slow.
The shift in how consumers interact with digital payment systems — from traditional credit cards to digital wallets, stablecoins, and integrated payment platforms — creates both opportunity and competitive pressure for retailers like Costco. The company’s explicit investment in “Costco Digital Wallet” enhancements is a direct acknowledgment that frictionless payment is a membership retention tool.
The bear argument: at 47x forward earnings with an LTM EBIT margin of 3.8%, Costco has essentially no multiple expansion available to it. Returns from here come primarily from earnings growth compounding. At 10–14% annual EPS growth (a reasonable estimate given historical pace), 47x forward earnings means the stock barely moves in nominal terms over 3–4 years even if the business executes flawlessly — because the multiple slowly compresses toward something more “normal.”
That is the precise tension in every Costco buy decision made above $900.
COST Stock Price Prediction 2026
The remainder of FY2026 (through August 2026) has two catalysts.
Q3 FY2026 (May 28, 2026): Consensus EPS of $4.90–$4.96 versus $4.65 in Q3 FY2025 — a ~6% year-over-year increase. Revenue expectations are approximately $62–$64 billion for the 12-week quarter. The key metric to watch: the worldwide membership renewal rate. If it holds above 89.5% despite the growing proportion of digital sign-ups (who renew at marginally lower rates), the valuation multiple is defensible. If it slips further toward 88%, the narrative around digital membership quality will sharpen.
March monthly sales were $28.41 billion — an 11.3% gain. Q3 should build on that momentum as construction season demand for home improvement items and seasonal merchandise accelerates. The digital comp of 23.3% in March suggests Q3 will likely show another 20%+ digital comp, reinforcing the platform narrative.
The tariff refund wildcard: Any clarity on whether Costco will receive $500M–$2B in tariff refunds would create a non-recurring income boost that pushes EPS significantly above consensus for whatever quarter it’s recognised. The timeline is uncertain — Trump predicted “five years” of court battles — but any positive development could provide a surprise upside.
| Scenario | FY2026 Price Range | Driver |
|---|---|---|
| Bear | $840–$950 | Multiple compression, renewal rate slips, gas deflation |
| Base | $950–$1,080 | On-trend delivery, 7% analyst upside, steady state |
| Moderate bull | $1,080–$1,150 | Digital acceleration confirmed, tariff refund progress |
| Bull | $1,150–$1,250 | New warehouse expansion beats, digital 25%+ comps, tariff win |
The $1,067.08 52-week high is the first meaningful resistance level. A sustained break above that level would signal the market is willing to re-rate COST above its recent peak multiple.
COST Stock Price Prediction 2027–2030
The 2030 case for Costco is one of the cleaner long-term narratives in US equities precisely because the business model doesn’t change.
TIKR’s mid-case puts approximately $1,410 per share by August 31, 2030 — an annualised return of approximately 8% from current levels. That’s below COST’s historical annual return of ~14.56% over 28 years (since its December 1997 listing at $22.32), reflecting valuation compression from current high multiples rather than business deterioration.
The specific variables for 2027–2030:
Warehouse expansion. 28 net new warehouses in FY2026, targeting 30+ per year thereafter. Each new warehouse represents approximately $200–$250 million in annual net sales at maturity, plus the associated membership revenue from new members in the catchment area. At 30 per year, Costco adds roughly 3.3% to its total warehouse count annually — and international warehouses in markets like China, Japan, Korea, and Spain tend to ramp to high membership density faster than US greenfield locations.
The membership fee cycle. Costco increased fees in September 2024 for the first time since 2017. The next increase is not scheduled, but the historical pattern suggests another increase sometime in 2027–2028. Each fee increase of $5 on Basic membership (from 81.4M members) generates approximately $407M in additional annual membership income at near-100% margins — a direct EPS contribution.
Digital 15–20% of revenue. If digital sales reach 15% of Costco’s projected $300B+ revenue by 2028–2029, that’s $45–60 billion in annual digital sales from a channel with potentially higher margins than warehouse sales (no building overhead per transaction). The broader digitalisation of retail payments is reshaping how consumers access large-format retail — and Costco’s combination of price advantage, subscription relationship, and digital infrastructure puts it better positioned than most.
AI-driven operational efficiency. CEO Vachris explicitly mentioned AI-driven inventory management in the Q2 FY2026 call — describing it as helping mitigate supply chain bottlenecks. At Costco’s scale, even 0.1% improvement in inventory turns or shrink reduction translates to hundreds of millions in annual savings. The role AI is playing in transforming operational efficiency across industries is particularly relevant for high-volume, low-margin businesses where small efficiency gains have proportionally large profit impacts.
| Scenario | 2027 | 2028 | 2030 |
|---|---|---|---|
| Bear | $820–$940 | $860–$980 | $900–$1,050 |
| Conservative | $1,000–$1,120 | $1,100–$1,250 | $1,200–$1,400 |
| Moderate bull | $1,150–$1,300 | $1,300–$1,500 | $1,500–$1,800 |
| Bull | $1,350–$1,550 | $1,550–$1,800 | $1,900–$2,300 |
TIKR’s mid-case of $1,410 by 2030 (FY2030 end, August 31, 2030) sits within the conservative-to-moderate bull range above. It implies an 8% annual total return — not spectacular by Costco’s own historical standards, but appropriate for a business at current valuations in a lower-multiple environment.
Is COST Worth Buying at $1,000?
Costco at $1,000 per share is a bet on two things simultaneously: the durability of the membership model and the trajectory of the multiple.
The business case is unambiguous. Costco has one of the most defensible competitive positions in global retail — a brand built on trust, a price promise that has been kept for 40 years, a membership model that generates consistent profit before any product is sold, and a digital growth trajectory that expands the addressable market without cannibalising the warehouse business. The 17% YTD gain while the market fell 3% tells you where institutional money goes when the macro outlook deteriorates.
The valuation case requires more nuance. At 47x forward earnings, Costco’s stock needs to compound earnings at 12–14% annually just to deliver 8% annual returns if the multiple slowly compresses to a still-premium 35x over the next decade. In a lower-growth macro environment, that earnings trajectory requires continued digital acceleration, warehouse expansion into international markets, and at least one more membership fee cycle.
Unlike businesses with binary risk profiles — where a single catalyst can double or halve the price — Costco is a slow, steady compounder. The investment case isn’t about catching a breakout; it’s about whether you want to own one of the world’s best subscription businesses at a price that assumes it keeps doing exactly what it’s been doing for the next decade.
The May 28 Q3 results and the worldwide membership renewal rate will tell you more about whether that thesis remains intact than any price target.
