The widest moats at $50 billion and up.
Wide tier (score 80–100) · market cap $50B or more
A moat at scale is a different achievement than a moat in a niche. At $50 billion and up, a company is big enough that competitors, regulators, and its own size all push against the returns — so holding a Wide-tier score (composite 80 or higher) here means the pricing power and returns on capital have survived being attacked from every direction. Scale doesn’t earn the score any slack: the same four sub-scores apply unchanged.
The trade-off is arithmetic, not opinion: the bigger the base, the harder it is for reinvestment to move the needle, and this screen says nothing about price — many of these names trade well above our conservative estimate of value. For the overlap of this quality bar with a sensible price, see Wide moats on sale. Scores come from primary SEC filings via the public methodology.
