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 five 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 value if growth stopped today. 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.

10 Wide-moat companies have no market-cap figure in our data, so they can’t be placed on either side of this screen’s size cutoff and aren’t listed.

A screen is a starting point for reading, not a recommendation. Scores reflect business quality as read from primary SEC filings; the disclosed owner-earnings range is model-dependent, not intrinsic value as fact or a price target. Sector labels are derived from SEC SIC codes and can differ from GICS classifications. Educational only — not investment advice. See the methodology and disclaimer.
