Each page lists the major subsidiaries, brands, and holdings of one large corporation — covering 30 of the biggest US companies, from Berkshire Hathaway and Alphabet to Coca-Cola and Procter & Gamble.

Why are so many of these companies in Delaware?

More than two-thirds of Fortune 500 companies are incorporated in Delaware, including most of the parent companies indexed above. They choose Delaware for its specialized Court of Chancery, its flexible corporate statute, and more than 230 years of predictable case law. You can form a company in the same jurisdiction these giants use: start with our Delaware LLC guide, compare the C-corporation route, or read why Delaware became the corporate capital.
