What is Berkshire Hathaway?

Berkshire Hathaway is an Omaha, Nebraska-based diversified holding company that owns one of the largest and most eclectic portfolios of businesses on earth — spanning insurance, freight rail, utilities, manufacturing, retail, and financial services — while simultaneously holding a $300+ billion equity portfolio in publicly traded companies.

Founded in 1839 as a New England textile mill and restructured under Warren Buffett's control in 1965, Berkshire Hathaway has compounded book value at roughly 18.1% per year for six decades, versus approximately 10.5% for the S&P 500 over the same period (including dividends). In August 2024 it became the first non-technology US company to cross a $1 trillion market capitalization, a milestone it has maintained into 2026.

The company operates more than 60 wholly owned subsidiaries including GEICO (writing more than $42 billion in premiums in 2025, the second-largest US auto insurer with ~11.5% market share), BNSF Railway (operating 32,000+ miles of track across 28 US states and two Canadian provinces), Berkshire Hathaway Energy (serving roughly 5 million electricity and gas customers), Clayton Homes, Dairy Queen, See's Candies, NetJets, and Pilot Flying J. Full-year 2025 operating earnings came in at $44.49 billion, while insurance float reached approximately $176 billion at year-end 2025 — acting as essentially free or negatively-priced capital deployed into long-term investments.

As of January 1, 2026, Greg Abel succeeded Warren Buffett as President and CEO. Buffett remains Executive Chairman. Full-year 2024 revenue was approximately $371.4 billion, ranking Berkshire consistently among the five largest US companies by revenue. With $373 billion in cash and equivalents at year-end 2025 — climbing to a record $397 billion by March 2026 — Berkshire holds more uninvested capital than virtually any other private institution, positioning it to make large opportunistic acquisitions under Abel's leadership.

How does Berkshire Hathaway make money?

Berkshire Hathaway earns money through two interlocking engines: (1) operating earnings from wholly owned subsidiaries across insurance, rail, energy, and manufacturing; and (2) investment income and capital gains from a $300+ billion public equity portfolio funded largely by insurance float.

The insurance float model is Berkshire's most distinctive structural advantage. Policyholders pay premiums upfront; claims are paid out over time. The difference — approximately $176 billion at year-end 2025, up nearly double from $87.7 billion a decade prior — sits on Berkshire's balance sheet as essentially free (or negatively-priced) investable capital when underwriting is profitable. Berkshire deploys this float into both wholly owned businesses and equity stakes, generating returns that accrue to shareholders without dilution. In 2025 alone, total insurance and reinsurance operations generated a combined technical profit of $7.26 billion and investment income of $12.51 billion.

There are no subscription fees or per-seat pricing at the holding company level. Each subsidiary prices its own goods independently. GEICO competes on auto insurance premiums and wrote more than $42 billion in premium volume in 2025 (approximately 11.5% of the US private passenger auto market). BNSF charges freight rail rates negotiated per commodity and route; in 2025 BNSF generated $8.1 billion in net operating cash flows and returned $4.4 billion to Berkshire in dividends. BH Energy generates regulated utility revenue. Clayton Homes sells manufactured housing and originates mortgages. Dairy Queen franchisees pay royalties of approximately 4–5% of gross sales.

Growth is driven by acquiring durable, capital-efficient businesses at fair prices and retaining all earnings — Berkshire has never paid a common dividend since 1967. Full-year 2025 operating earnings totaled $44.49 billion, down modestly from a record $47.4 billion in 2024 partly due to California wildfire losses weighing on reinsurance underwriting. The company generated $46 billion in net operating cash flows in 2025, against a five-year average exceeding $40 billion, demonstrating the countercyclical power of a portfolio that spans insurance, freight rail, energy, and manufacturing.

How much funding has Berkshire Hathaway raised?

Berkshire Hathaway has never raised traditional venture or private equity funding. It is a publicly traded company on the NYSE (BRK.A / BRK.B), with a market capitalization of approximately $1.02–1.06 trillion as of June 2026, and $373 billion in cash at year-end 2025 climbing to a record $397 billion by March 2026.

Berkshire Hathaway's original capital formation predates modern equity markets. Warren Buffett began acquiring shares in the then-failing textile company in 1962 at approximately $7.60 per share, taking control in May 1965 with roughly $14 million of personal capital. The company listed its Class A shares on the NYSE on November 29, 1988 — they have never been split and trade at among the highest per-share prices on any exchange globally. Class B shares (BRK.B) were created in 1996 at 1/30 of Class A's economic value, then restructured to 1/1,500 after a 50-for-1 split in 2010 that coincided with the BNSF Railway acquisition.

Berkshire's capital raises have never followed conventional fundraising rounds. Rather than issuing equity to grow, the company reinvests operating cash flows and occasionally issues shares as acquisition currency. The $22 billion General Re acquisition in 1998 was partly funded by Berkshire stock. The BNSF Railway acquisition in 2010 was valued at approximately $44 billion including assumed debt ($26.5 billion equity component), partly paid in new Berkshire shares and triggering the BRK.B 50-for-1 split. The $37.2 billion Precision Castparts acquisition in January 2016 (announced August 2015 at $235 per share) was the company's largest all-cash deal to date. The $11.6 billion Alleghany acquisition completed in October 2022 — at $848.02 per share, representing 1.26x book value — was Berkshire's largest since Precision Castparts.

At year-end 2025, Berkshire held $373.3 billion in cash and equivalents — one of the largest uninvested cash reserves in corporate history — down slightly from a record $381.6 billion in Q3 2025. By the end of Q1 2026 that figure had climbed to a new record of $397.4 billion under CEO Greg Abel. Shareholders' equity stood at approximately $717 billion. Total assets exceeded $1.2 trillion. Berkshire has not paid a common stock dividend since 1967, preferring to retain and redeploy all capital.

Who are Berkshire Hathaway's competitors?

As a diversified insurance-anchored conglomerate, Berkshire's nearest structural peers are other holding companies that use insurance float or retained earnings to acquire businesses, plus major pure-play insurers that compete directly with GEICO and General Re.
