Berkshire Hathaway is a holding company with a wide array of subsidiaries engaged in diverse activities. The firm's core business segment is insurance, run primarily through Geico, Berkshire Hathaway Reinsurance Group, and Berkshire Hathaway Primary Group. Berkshire has used the excess cash thrown off from its operations to acquire Burlington Northern Santa Fe (railroad), Berkshire Hathaway Energy (utilities and energy distributors), and the companies that make up its manufacturing, service, and retailing operations (which include Precision Castparts, Lubrizol, Clayton Homes, Marmon, and IMC/ISCAR). The conglomerate is unique in that it is run on a completely decentralized basis. Berkshire is expected to generate close to $375 billion in revenue in 2025.

Coinbase Global, Inc. Class A Common Stock

COIN

Founded in 2012, Coinbase is the leading cryptocurrency exchange platform in the United States. The company intends to be the safe and regulation-compliant point of entry for retail investors and institutions into the cryptocurrency economy. Users can establish an account directly with the firm, instead of using an intermediary, and many choose to allow Coinbase to act as a custodian for their cryptocurrency, giving the company breadth beyond that of a traditional financial exchange. While the company still generates the majority of its revenue from transaction fees charged to its retail customers, Coinbase uses internal investment and acquisitions to expand into adjacent businesses, such as prime brokerage and data analytics.
