Wide Moat Stocks

A wide economic moat is the strongest verdict in moat investing: a structural competitive advantage so durable that the company is expected to fend off competitors and sustain above-average returns on capital for two decades or more. The term comes from Warren Buffett, who compared great businesses to castles protected by moats — the wider the moat, the harder it is for rivals to attack the castle. Only a minority of publicly traded companies earn a wide moat rating, because most competitive advantages erode: patents expire, brands fade, and technology shifts open the gates.

Every company on this list has been analyzed by MoatScan’s AI across five moat pillars — network effects, switching costs, intangible assets, cost advantages, and efficient scale — each scored from 0 to 10. The Moat Score shown below is a weighted average of those pillar ratings on a 0–100 scale, and the Wide Moat rating itself is a separate, independent judgment about durability: how long the advantages should last, not just how strong they are today. A company can post a high score yet earn only a narrow rating if its advantages look vulnerable to disruption.

A wide moat alone does not make a stock a buy — even the best business can be a poor investment at the wrong price.
