Amazon.com, Inc.: Not a retailer. It's an attention tollbooth disguised as a cardboard box. Andy Jassy inherited this architecture from Bezos in 2021 and has spent three years doing something his predecessor never prioritized: making it efficient. The result? If you're trying to understand Amazon in 2025, forget the delivery vans. Follow the margins. Forget the revenue number for a second. It's converting the act of selling things into four separate, higher-margin revenue streams that most people don't even notice. Start with the trick that makes the whole thing work: negative working capital. Customers pay Amazon immediately. That gap — multiplied across hundreds of billions in transactions — creates a permanent float of free cash that funds expansion without borrowing. The problem is, it's the same trick insurance companies use, except Amazon does it with toothpaste and phone chargers. The marketplace is where the model gets clever. It's a tax on a tax. AWS is the profit engine that makes everything else possible. Thirty-seven percent margins. Most companies just don't bother. Advertising is the segment that changed the financial narrative. They're buying. The ad appears at the moment of purchase intent, inside a commerce environment where conversion is directly measurable. Brands can't ignore it. They comparison-shop less. They try more Amazon services. The rest — Whole Foods, Amazon Fresh, Kindle, Echo, Fire TV, One Medical, Amazon Pharmacy — these are either traffic generators, data collectors, or long-horizon bets on massive markets. Devices are sold at or near cost to drive service engagement. None of these segments need to be independently profitable because the financial architecture doesn't require it. Retail generates cash through working capital dynamics. AWS and advertising generate profit. Everything else is funded by the spread between the two. When a mid-size retailer decides where to sell online, the decision comes down to one factor: where are the buyers already standing? Amazon has 200 million Prime members with credit cards on file and one-click purchasing enabled. That's not a marketplace. That's a captive audience with pre-authorized wallets. Walmart, Shopify, and every other e-commerce platform compete for the remaining attention. Walmart is the rival that keeps Andy Jassy awake. Americans visit Walmart stores 150 million times per week. Each visit is a chance to attach an online order, sign up for Walmart+, or scan a QR code that pulls them into digital commerce. Walmart's 4,700 US stores function as fulfillment nodes that enable same-day delivery without the warehouse construction costs Amazon bears. The pitch is consolidation: you already pay us for Office, Teams, security, and identity management. Adding Azure means one vendor, one bill, one support contract. For a CIO under budget pressure, that's compelling regardless of whether AWS has more services. If enterprises standardize on GPT-4 for internal AI and GPT-4 runs best on Azure, the workload follows the model. Shopify represents the anti-Amazon thesis: merchants who want to own their customer relationship rather than rent it from a marketplace. 200 million behaviorally locked-in Prime members. Jassy spent 2023 cutting: 27,000 corporate roles eliminated, dozens of facilities closed or delayed, the fulfillment network reorganized from a national spaghetti map into eight regional hubs. By FY2024, the results were undeniable. It goes after the exact mechanism that converts marketplace traffic into Amazon's highest-margin revenue. The FTC alleges that Amazon punishes sellers who offer lower prices elsewhere by burying them in search results and stripping Prime eligibility. Structural remedies could force separation of marketplace from retail, restrict how seller data flows between divisions, or limit the bundling of fulfillment with search ranking. Any of those outcomes would hit billions in annual profit. That's not a crisis. It's a slow squeeze. The labor situation is the one that keeps me up at night if I'm an Amazon board member. And unlike AWS margins, you can't engineer your way out of it with better algorithms. It's density. Amazon's per-unit delivery cost drops with every additional package in a given zip code. But the logistics network is the obvious part. That's not a rational calculation — it's a psychological one. Most CTOs look at that equation and decide to stay. Breaking into that loop requires simultaneously offering better selection AND better prices AND faster delivery AND a large enough audience to attract sellers. Nobody has done it. When someone searches on Amazon, they're holding a credit card. Purchase intent at the moment of buying decision is structurally different from informational intent, and it's why Amazon's ad conversion rates justify the premium brands pay. Andy Jassy's Amazon is not Jeff Bezos's Amazon. That's the point. It's the regionalization of the US fulfillment network into eight geographic zones where orders are fulfilled locally instead of shipped cross-country. Boring. Defining. The big bet is AI infrastructure. Custom Trainium2 chips for training. Inferentia2 for inference. Amazon Bedrock as the managed service layer where enterprises access foundation models from Anthropic, Meta, Mistral, and Amazon's own Nova family. Amazon Q as the enterprise AI assistant. It doesn't need to be the flashiest AI platform. It needs to be the most convenient one for existing customers. Amazon has to sell it cold. The advertising trajectory is more certain. Prime Video ads reach 200 million households. Grocery surfaces through Whole Foods and Fresh create physical-world ad inventory. The DSP extends Amazon's purchase-intent data across the open web. Healthcare is the decade bet. But healthcare moves at regulatory speed, not Amazon speed. Three years from now, this is still a work-in-progress. The FTC lawsuit is the wild card nobody can model. Structural remedies that separate marketplace from retail would break the flywheel economics that fund everything else. My judgment: Amazon settles with behavioral concessions that cost money but preserve architecture. Nobody remembers this, but Amazon almost got named Cadabra. As in abracadabra. Jeff Bezos's lawyer talked him out of it because it sounded too much like 'cadaver' over the phone. Bezos was at D. E. Shaw in Manhattan, one of the most secretive and profitable quantitative trading firms on Wall Street, pulling in the kind of compensation that makes people stay forever. Not 23 percent. Twenty-three hundred. He made a list of twenty product categories that could work online and picked books for coldly rational reasons. Three million titles in print. No physical store could stock more than 150,000. An online catalog could offer everything. The product was cheap to ship, impossible to damage, and attracted exactly the kind of educated early-adopter who was already comfortable with the internet in 1994. Here's what I find fascinating about the founding decision: Bezos didn't quit his job because he was passionate about books. He quit because he ran a mental exercise he called the 'regret minimization framework.' At eighty years old, would he regret not trying this? Obviously yes. Would he regret trying and failing? The asymmetry of regret made the decision trivial. His boss David Shaw took him on a walk through Central Park, told him it was a great idea for someone who didn't already have a great job, and wished him well. Bezos and MacKenzie Scott packed a car and drove from New York to Seattle. He chose Seattle for two reasons that had nothing to do with tech culture: a major book distributor (Ingram) had a warehouse in nearby Roseburg, Oregon, and Washington state's small population meant fewer customers would owe sales tax. Within the first week, they'd sold books to customers in all fifty states and forty-five countries. They hit that number in the first year. But the near-death moment came later. The dot-com crash of 2000-2001 cratered the stock from over $100 to under $6. The IPO had happened earlier, May 15, 1997, at $18 per share.

Costco Wholesale Corporation: Costco's retail markup cap is approximately 15 percent on national brands and 14 percent on Kirkland Signature products. A conventional retailer marks up 25 to 50 percent. Walmart marks up 24 percent on average. Costco's margin discipline is so extreme that the company structurally cannot earn significant profit from selling products — which is exactly the point. The profit is in the membership fee, and the membership is so valuable that 93% of North American members renew it every year. Founded in 1983 by James Sinegal and Jeffrey Brotman in Issaquah, Washington — after the merger with Price Club in 1993 — Costco operates 914 warehouses globally and generated $275.2 billion in FY2025 revenue under CEO Ron Vachris, who took over in 2024. The membership fee business generated almost all of the company's operating profit. Everything else — the pallets of paper towels, the rotisserie chickens, the Kirkland Cashmere sweaters — serves primarily to justify the annual membership renewal. The Kirkland Signature private label is the financial multiplier that most analysts underweight. Kirkland items typically carry higher gross margins than the national brands they sit next to, while priced lower. The formula works because Kirkland's volume is large enough to negotiate manufacturing contracts at scale that national brand companies can't match at retail. When Costco sells Kirkland olive oil, it earns more per unit than it earns selling Bertolli at a lower price — and the customer gets a better deal. Net income of $8.1 billion on $275.2 billion in revenue tells you almost nothing about Costco's actual business quality. The $396.7 billion market capitalization — roughly 49x trailing earnings — tells you what the market believes about the durability of member loyalty, the Kirkland brand, and the pricing discipline that has made Costco the retailer that customers actively root for.

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

Amazon.com, Inc. business model: That's roughly what Google pays Amazon every year just to remain the default search engine on Fire tablets and Alexa devices. Amazon pays suppliers 60-90 days later. These merchants pay roughly fifteen percent in referral commissions on every sale, plus Fulfillment by Amazon fees if they want Prime eligibility (and they do — Prime badges increase conversion rates dramatically). The margins are structurally better than first-party retail because Amazon earns fees without touching inventory. But here's the underrated factor: those same sellers now spend heavily on advertising just to be visible in search results on a platform they're already paying commissions to use. The division sells compute, storage, databases, machine learning tools, and about 200 other services on a pay-as-you-go basis. Prime doesn't just generate fees — it rewires shopping behavior. Members consolidate purchases on Amazon because every order feels free after the annual payment. The $139 is a sunk cost that makes the marginal cost of loyalty feel like zero. Google doesn't need cloud profits the way Amazon does — search advertising generates enough cash to subsidize aggressive cloud pricing indefinitely. It's the pricing discipline Google destroys for the entire industry. Shopify powers millions of independent stores, processes hundreds of billions in gross merchandise volume, and has built fulfillment infrastructure that gives small brands Amazon-like delivery speeds without Amazon's fees or data extraction. A marketplace where third-party sellers pay referral fees, fulfillment fees, and advertising fees that collectively approach 50% of their revenue — and still can't leave because that's where the customers are. The advertising business monetizes the exact moment of purchase intent. If that's true — and the evidence appears substantial — then the entire flywheel of seller dependence → advertising spend → fee extraction is built on coercive practices rather than pure value creation. A new entrant shipping one package to a neighborhood pays the same driver cost as Amazon shipping forty. Every subsequent purchase feels free. They can't match the feeling of having already paid. One Medical plus Amazon Pharmacy plus Prime integration creates something no competitor has assembled: a vertically integrated care-and-commerce loop where the company that delivers your medication also schedules your appointment and sells you the supplements your doctor mentioned.

Costco Wholesale Corporation business model: A typical grocery chain or department store earns profit by marking up products — buy low, sell higher, pocket the spread. That fee income flows almost entirely to the bottom line because collecting it costs nearly nothing — no inventory risk, no spoilage, no freight. Everything else the company does — moving pallets, negotiating with Procter & Gamble, running gas stations — exists to make that $65 or $130 annual card feel like a bargain. Gold Star costs $65 per year and gives household access to warehouses and online pricing. The result is lower unit costs, which get passed to members as lower shelf prices, which justifies the membership fee, which funds the next cycle. Costco controls sourcing, quality standards, and pricing through its Costco Wholesale Industries subsidiary, which means it doesn't just slap a label on someone else's product. Ancillary services — pharmacy, optical, hearing aids, travel, auto buying, the Costco Anywhere Visa by Citi — add layers of value that make the annual fee feel increasingly justified without requiring significant capital investment per service. The metric that matters most for Costco isn't revenue growth. Revenue model: Costco sells goods at low margins and earns a large share of profit from annual membership fees, supported by high-volume warehouse operations. But it explains why Costco commands a $65 membership fee against Sam's Club's $50, why renewal rates sit above 93%, and why members talk about the store the way people talk about restaurants they love — with genuine enthusiasm rather than transactional loyalty. Costco members feel like they belong to something. Sam's Club members feel like they're saving money. It either passes the cost through (which makes members feel less special) or eats it (which compresses already-thin margins). The 2024 fee increase — the first in seven years — tested whether the relationship could absorb a price hike. The problem is, you'd need suppliers willing to give you rock-bottom pricing on day one, which they won't do without proof of volume. Once you've paid $65 or $130, you feel compelled to shop there to "get your money's worth." That's not rational — the fee is sunk — but it's powerful. Carrying 3,800 SKUs instead of 30,000 means each item sells in enormous quantities. That gives Costco pricing use that even Walmart struggles to match on a per-item basis. Costco pays above-market wages — starting around $18-19/hour with benefits — and gets turnover rates far below retail averages. Executive membership upgrades are pure revenue-per-member growth. Costco didn't flinch — it kept opening warehouses, kept markups at 14%, and let the internet kill everyone else's margins while its membership fees quietly compounded. Amazon, Walmart, and Sam's Club are competing to make leaving your house feel unnecessary. Sol Price had a rule: never let the customer feel stupid for shopping with you. Asking households to pay $25 per year (the original fee) just to walk through the door was bizarre in 1983. The fee paid for itself in a single shopping trip, and after that, every subsequent visit felt free. Both companies were growing, but the overlap was creating pricing pressure and real estate conflicts. By then, the culture had calcified into something remarkably durable: cap markups at 14-15%, carry fewer than 4,000 items, pay employees well, open warehouses slowly and carefully, and never let the customer feel like they're being played.

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

Amazon.com, Inc. competitive advantage: Amazon's counter — Bedrock offering multiple models including Anthropic's Claude, custom Trainium chips for cost advantage, and deeper service integration — is technically sound but requires customers to actively choose complexity over convenience. The structural moat remains formidable. AWS's 200+ services create switching costs measured in years of re-engineering. But switching costs in cloud are genuinely brutal — companies don't migrate production workloads on a whim. Every dollar of wage increase, every safety improvement, every concession to union demands flows directly to the bottom line at a scale that no pure software company faces. But cost isn't even the real barrier. The counterintuitive reality is the behavioral lock-in created by Prime. The sunk cost fallacy working in Amazon's favor, at scale, renewed annually. The switching costs aren't theoretical. The marketplace network effect is textbook but worth stating plainly: more sellers create more selection, which attracts more buyers, which attracts more sellers, which generates more advertising revenue, which funds lower prices and faster delivery. Because Bezos understood something about network effects that most retailers still don't: the store with the most selection wins, and you don't need to own the inventory to have the selection.

Costco Wholesale Corporation competitive advantage: Competitive position: Costco's advantage is its membership model, high inventory turnover, low markups, private-label strength, and unusually strong customer loyalty. That's a strange competitive advantage to have. Walmart's supply chain means Sam's Club can price aggressively in categories where scale matters. BJ's Wholesale occupies the East Coast niche but hasn't scaled beyond 250 clubs in decades. Not any single advantage, but the fact that assembling all of them simultaneously is nearly impossible for a new entrant. It wasn't built on technology or patents or network effects.

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

Amazon.com, Inc. growth strategy: The company expanded into every retail category, launched AWS in 2006, acquired Whole Foods in 2017, built a logistics network rivaling UPS and FedEx, and grew an advertising business that now exceeds $56B annually. That's not growth. The irony is, if you're looking at Amazon as an investor, the question isn't whether revenue will grow — it will, at roughly ten to twelve percent annually. The question is whether the high-margin businesses (AWS, advertising, seller services) continue growing faster than the low-margin retail base. If yes, operating margins expand toward fifteen percent or higher. If AI infrastructure spending outpaces AWS revenue growth, or if advertising saturates, the margin story stalls. The longer-term risk is subtler: if the AI infrastructure cycle requires $50-80 billion in annual capex just to stay competitive, and revenue growth doesn't keep pace, AWS margins compress. What would it actually cost to build a second Amazon? Companies build on Lambda, DynamoDB, SageMaker, Bedrock. Bezos built by expanding into everything — books to toys to cloud to groceries to healthcare to space — and worrying about margins later. Jassy inherited a company that had over-expanded during the pandemic (doubled warehouse square footage, hired 750,000 people, then watched demand normalize) and decided the growth story needed to become a margin story. The most important thing he's done isn't a new product launch. Advertising growth is the highest-margin play and requires the least incremental investment. Sponsored products are expanding into grocery, pharmacy, and physical retail. If you're researching Amazon for anyone evaluating the stock, the advertising growth rate is the figure that tells the whole story — it reveals whether the flywheel is still accelerating or plateauing. He'd stumbled on a statistic: web usage was growing at 2,300 percent annually.

Costco Wholesale Corporation growth strategy: Its strategy centers on Costco is expanding warehouses globally, growing e-commerce carefully, strengthening Kirkland Signature, and keeping prices low to defend renewal rates. The problem is, Strategic direction: Costco is expanding warehouses globally, growing e-commerce carefully, strengthening Kirkland Signature, and keeping prices low to defend renewal rates. Costco's growth strategy is anchored by a single priority with a handful of supporting moves. Most analysts miss that this restraint is the strategy, not a failure to execute.

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

Amazon.com, Inc.: $20 billion. The $716.9B in FY2025 revenue gets all the press, but the real story is how little of that matters to the bottom line. Strip away the razor-thin retail margins and what you find is a $105 billion cloud computing empire, a $56 billion advertising machine, and a subscription flywheel with 200 million paying households — all of it funded by a retail operation that exists primarily to generate the traffic and data that make everything else work. Net income nearly doubled from $30.4 billion to $59.2 billion in a single year. Under CEO Andy Jassy, Amazon reported $716.9B in FY2025 revenue with approximately 1.5 million employees worldwide and a market capitalization exceeding $2 trillion. $638 billion sounds impressive until you realize that most of it — the online stores segment, the stuff in cardboard boxes — operates on margins so thin you could paper a wall with them. This segment pulled in approximately $140 billion in FY2024. $105 billion in FY2024 revenue. Roughly $39 billion in operating income. $56 billion in FY2024, growing north of twenty percent annually, with margins estimated above fifty percent. Prime membership ($139/year in the US) generates an estimated $40 billion in subscription revenue, but that understates its value by an order of magnitude. Healthcare is a $4 trillion US market where Amazon is still in the first inning. FY2025 revenue reached $716.9B with approximately 1.5 million employees and a market capitalization exceeding $2 trillion. The business model combines low-margin retail (generating cash through negative working capital), high-margin AWS cloud services ($105B in FY2024), and fast-growing advertising revenue ($56B). Not because Walmart's e-commerce is better — it isn't — but because Walmart has something Amazon spent $13.7 billion trying to buy with Whole Foods: grocery frequency. Over $100 billion in logistics infrastructure. The number that tells the real Amazon story isn't $638 billion in revenue. It's the jump from $30.4 billion to $59.2 billion in net income — a near-doubling in a single fiscal year. FY2022 was the low point: a $2.7 billion net loss driven by pandemic overexpansion — too many warehouses, too many employees, too much optimism about permanently elevated e-commerce demand. AWS contributed $105 billion in revenue and $39 billion in operating income — thirty-seven percent margins on a business that represents less than seventeen percent of total sales. Advertising brought in $56 billion at estimated margins above fifty percent. The market cap above $2 trillion prices in the optimistic scenario. I've seen estimates north of $150 billion for the logistics network alone — the 1,000+ fulfillment centers, the 90-aircraft air cargo fleet, the tens of thousands of delivery vans, the sortation facilities, the last-mile stations. By 2028, Amazon will either be the default infrastructure layer for enterprise AI or it will have spent $100 billion trying. This business hits $80 billion by 2027 without requiring any technological breakthrough — just more surfaces and better targeting on existing ones. Five years from now, it's either a $30 billion business or a write-down. That's the level of improvisation happening in the summer of 1994 — a thirty-year-old quant from a hedge fund, driving cross-country with his wife while dictating a business plan from the passenger seat, hadn't even settled on a name for the company that would eventually be worth $2 trillion. Bezos had told early employees that if they sold $1 million in books by 2000, he'd consider it a success.

Costco Wholesale Corporation: Costco's revenue has grown at a consistent pace: $226.9 billion in FY2022, $242.3 billion in FY2023, $254.5 billion in FY2024, $275.2 billion in FY2025. That's roughly 7% annualized growth at a company with $275 billion in revenue — an achievement that requires opening new warehouses, expanding internationally, and growing same-warehouse sales in an existing footprint of 914 locations. Net income of $8.1 billion on $275.2 billion in revenue is a 2.9% net margin that understates the business quality dramatically. The membership fee revenue flows almost entirely to the bottom line because collecting it costs nearly nothing — no inventory, no spoilage, no freight. The merchandise business is intentionally run near breakeven to maximize the value proposition that justifies the membership fee. The $396.7 billion market capitalization — roughly 49x trailing earnings — is the clearest signal of how the market values membership-based retail. Investors are not pricing Costco as a low-margin merchandise business. They're pricing it as a recurring revenue platform with exceptional customer retention, growing global footprint, and a private label that commands premium margins on high-volume categories. Warehouse-level economics support the premium. A new Costco warehouse typically generates first-year revenue around $130 million and reaches $250 million-plus within three years, with occupancy costs fixed through long-term leases. The capital required to open a warehouse is large but the payback period is short relative to the lifetime revenue that follows. International expansion — Canada, Japan, Korea, Australia, and increasingly China — applies the same economics to markets where the membership model hasn't yet saturated.
