How Berkshire Hathaway Makes Money

Berkshire's business model is capital allocation on top of a decentralized group of operating companies. Subsidiary managers run their own businesses, with no corporate budget submissions and no committee structure at headquarters, and send surplus cash to Omaha. The chief executive then decides where it goes: into existing operations, new acquisitions such as the $9.7 billion purchase of OxyChem completed in January 2026, marketable equities, or Berkshire stock when it trades below estimated intrinsic value. Insurance is the core. Policyholder money held before claims are paid, which Berkshire calls float, reached $176 billion at the end of 2025, and the group has earned a pre-tax underwriting profit in each of the three years to 2025, so that float has cost less than nothing. Berkshire has not paid a dividend since 1967, which is why retained earnings and float, rather than outside capital, fund almost everything it buys.

Berkshire's size limits what can move its results, so growth comes from large purchases, reinvestment inside existing businesses and buying back its own stock. Buffett described the 2009 BNSF agreement, a $34 billion investment in the railroad, as an all-in wager on the economic future of the United States. The 2025 and 2026 examples are smaller: a $9.7 billion purchase of Occidental's chemicals business, OxyChem, and the family-owned pest-control manufacturer Bell Laboratories. Abel has said Berkshire will buy productive businesses in preference to holding Treasuries, but will not stretch on price, which is why cash and Treasury holdings still exceeded $370 billion at the end of 2025 and no shares were repurchased that year. Berkshire also adds to listed holdings when prices suit it, paying $16.9 billion for equity securities during 2025.
