KKR is one of the world's largest alternative-asset managers, with $796.5 billion in total managed assets, including $638.4 billion in fee-earning assets under management, at the end of June 2026. The company has two core segments: asset management (which includes private markets—private equity, credit, infrastructure, energy, and real estate—and public markets—primarily credit and hedge/investment fund platforms) and insurance (following the firm's initial investment in, and then ultimate purchase of, Global Atlantic Financial Group, which is engaged in retirement/annuity and life insurance lines as well as reinsurance).

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.
