Economic Moat Examples: Real-World Case Studies That Actually Matter
Every company claims to have a competitive advantage. The annual report always says something about "market-leading position" or "differentiated approach." The financial statements tell a different story. Most companies earn mediocre returns on capital because they have no real moat.
The test is simple: sustained returns on invested capital well above the cost of capital, maintained through recessions, competitive attacks, and technology shifts. Here are the companies that pass that test, organized by moat type, with the numbers to prove it.
Network Effects: The Rarest and Most Powerful Moat
Network effects create a self-reinforcing loop: each new user makes the product more valuable for every existing user. Once a network reaches critical mass, displacing it becomes nearly impossible.
Visa (V): The Global Payment Toll Booth
Visa processes transactions in over 200 countries with capacity for 65,000 messages per second. The moat is structural: merchants accept Visa because consumers carry it, and consumers carry it because merchants accept it.
Any challenger faces a coordination problem that money alone cannot solve. A new payment network would need to simultaneously convince millions of merchants to install new terminals AND millions of consumers to carry a new card. Visa has been building this network for over 60 years.
The financial evidence is unmistakable:
- Operating margins: above 65%
- ROIC: above 35%
- Revenue growth: roughly 10% annually in what should be a mature market
These are not the economics of a company facing real competition. They are the economics of a toll booth on the global payments highway. See our full Visa analysis.
NVIDIA (NVDA): The CUDA Developer Flywheel
NVIDIA's moat is widely misunderstood as hardware superiority. The real moat is CUDA, the parallel computing platform with over 4 million developers building on it. Every major machine learning framework (PyTorch, TensorFlow) is optimized for CUDA first. Every AI researcher learns CUDA in graduate school. Every cloud provider stocks NVIDIA GPUs because that is what customers demand.
AMD can build competitive silicon. What AMD cannot replicate is a decade of accumulated developer tools, libraries, university curricula, and production codebases written for CUDA.
Consider what OpenAI would need to do to switch away from CUDA: rewrite their entire training infrastructure, retrain engineers, re-optimize frameworks. Even if AMD chips were 50% cheaper, the switching cost exceeds the savings.
NVIDIA's 49% ROE and 42% ROIC on minimal leverage (D/E: 0.37) reflect this compounding advantage. The returns come from the ecosystem, not just the chips.
Alphabet/Google (GOOGL): The Search Data Flywheel
Google processes roughly 8.5 billion searches daily. Each search generates data that improves the algorithm, which attracts more users, which generates more data.
The less obvious moat sits on the advertiser side. Google's ad auction has more bidders than any competitor, which drives higher prices per click, which generates more revenue to reinvest in search quality. This two-sided network effect explains how Google maintains 92% global search share despite Microsoft spending billions on Bing.
After two decades of this compounding, the data advantage is essentially insurmountable.
Switching Costs: The Quiet Compounder
Switching cost moats lack glamour but are remarkably durable. When migration is painful, customers tolerate modest price increases year after year. The compounding effect of 3-5% annual price hikes on a 95% retention base is extraordinary.
Microsoft (MSFT): Layers Upon Layers
Microsoft's enterprise moat is not one switching cost but dozens stacked on top of each other. Active Directory manages authentication. SharePoint stores institutional documents. Outlook handles email. Teams handles communication. Azure hosts workloads. Excel models run the finance department.
Migrating a 10,000-person enterprise off Microsoft would cost $50-100 million when factoring in licensing, data migration, retraining, and operational risk. This is why Microsoft maintains 95%+ customer retention and earns 37% ROE with 32% ROIC.
Charlie Munger captured the principle well: "The great lesson in microeconomics is to discriminate between when technology is going to help you and when it's going to kill you." Microsoft is the rare case where technology change (the cloud transition) actually deepened switching costs rather than weakening them. Moving from on-premise Office to Office 365 gave Microsoft a subscription revenue stream AND increased integration with Azure.
Adobe (ADBE): File Format Lock-In
Adobe's moat operates on multiple levels. At the simplest level, .PSD, .AI, and .INDD files require Adobe software to open properly. A design agency with 50,000 Photoshop files cannot migrate to Figma without converting or losing formatting on every single one.
The deeper switching cost is workflow integration. Creative teams build entire pipelines around Adobe: Photoshop for editing, Illustrator for vectors, Premiere for video, After Effects for motion graphics. These tools share assets, presets, and libraries seamlessly. Replacing one means rebuilding the entire chain.
Adobe earns 40% ROE and 35% ROIC with a subscription churn rate below 5% annually. The company raises Creative Cloud prices regularly, and customers absorb it because the alternative is worse.
Paychex (PAYX): Mission-Critical Lock-In
Payroll is the ultimate "don't mess this up" function. One missed paycheck triggers employee complaints, potential lawsuits, and regulatory scrutiny. Paychex processes payroll for over 700,000 small and medium businesses, and the switching calculus for a CFO is simple: even if a competitor costs 10% less, the risk of errors during migration is not worth it.
Paychex's 42% ROE and 30% ROIC on a conservative balance sheet (D/E: 0.46) are not the numbers of a company competing on price. They are the numbers of a company whose customers are locked in by the consequences of leaving.
Intangible Assets: What Money Cannot Buy
ASML: The Only Supplier
ASML holds a literal monopoly on extreme ultraviolet (EUV) lithography machines, the equipment required to manufacture the most advanced semiconductor chips. There is no second source. Intel, TSMC, and Samsung all depend on ASML.
This monopoly was earned through decades of R&D investment exceeding $10 billion and partnerships with optics specialists like Zeiss. A new entrant would need to replicate not just the machine (which costs $380 million each) but the entire supply chain of precision components that no one else makes.
ASML's 55% ROE and 46% ROIC are the financial signature of an irreplaceable supplier.
Texas Pacific Land (TPL): Irreplaceable Real Assets
TPL owns approximately 880,000 acres in the Permian Basin, the most productive oil-producing region in America. The company does not drill; it collects royalties and water rights fees from operators who do. The land requires virtually zero capital expenditure to maintain.
The result is financial performance that looks almost absurd: 45% ROE, 56% ROIC, and zero debt. These returns exist because the asset (West Texas land with mineral rights) cannot be replicated, moved, or competed away.
Cost Advantages: Structural Efficiency
Old Dominion Freight Line (ODFL): Network Density
In less-than-truckload (LTL) shipping, route density determines profitability. ODFL has spent decades building the densest service center network in North America, with facilities positioned to minimize empty miles.
A new entrant would need to build hundreds of service centers simultaneously to offer comparable coverage. Building them one at a time does not work because shippers need nationwide reach. This catch-22 protects incumbents.
ODFL earns 29% ROE and 28% ROIC in an industry where most competitors struggle to earn their cost of capital.
Costco (COST): The Membership Flywheel
Costco's moat is structural, not operational. Membership fees ($4.2 billion annually) cover the majority of operating costs, which means Costco can sell products at near break-even and still earn a profit. Traditional retailers cannot match Costco's prices without going bankrupt.
The flywheel reinforces itself: low prices attract members, membership fees fund operations, low costs enable low prices. Renewal rates above 90% confirm genuine value.
Charlie Munger served on Costco's board for decades and called it "one of the most admired retailing institutions in the world."
Multiple Moats: The Compounding Fortress
The most durable competitive positions combine multiple moat types. When network effects, switching costs, and brand power reinforce each other, the result is a business that can compound wealth for decades.
Apple (AAPL): Ecosystem Integration
Apple combines brand power (premium pricing), ecosystem switching costs (iMessage, iCloud, app library), and network effects (AirDrop, FaceTime work better with more Apple users). Customer retention exceeds 90% and services revenue surpasses $95 billion annually at 72% gross margins.
The non-obvious insight: Apple's real moat in the US is the social switching cost of leaving iMessage. Apple holds over 55% smartphone market share in America. Leaving the Apple ecosystem means leaving the group chat. That social cost keeps customers locked in more effectively than any feature comparison.
Amazon (AMZN): Layered Advantages
Amazon operates three distinct moat-protected businesses. The marketplace benefits from network effects (more sellers attract more buyers). AWS benefits from switching costs (migrating cloud workloads costs millions and months of engineering time). Prime benefits from bundling economics (200 million members paying $139/year for shipping, video, music, and grocery delivery).
Each business reinforces the others. E-commerce cash flow funded AWS infrastructure. AWS margins subsidize e-commerce pricing. Prime membership increases purchase frequency.
When Moats Die: Cautionary Examples
Kodak had genuine moats: brand recognition, distribution infrastructure, patents, and manufacturing scale. All became worthless when digital photography eliminated the need for film. Moats built around a specific technology are vulnerable when the underlying technology becomes obsolete.
BlackBerry Messenger (BBM) had real network effects among business users in the early 2000s. But network effects that build quickly can collapse quickly. When the iPhone offered a superior experience, users left in waves, and each departure made the platform less valuable for everyone remaining. Market share fell from 50% to under 1% in five years.
The lesson: network effect moats require ongoing product excellence. The network locks users in only as long as the product remains competitive.
Applying Moat Analysis
The common thread: real moats produce measurable financial results. High ROE, high ROIC, strong margins, and predictable cash flows are consequences of competitive advantages that protect profits from competition.
When evaluating any company, start with the numbers. If a business earns mediocre returns on capital, it does not have a moat, regardless of what the annual report claims. If the returns are exceptional and sustained over a full business cycle, dig deeper to understand the structural advantage driving them.
