Warren Buffett got rich by buying undervalued businesses and stocks, holding them for decades, and using Berkshire Hathaway as the vehicle that kept the profits working. His start was small and self-funded. A paper route and soft-drink sales paid for his first stock at age 11 and a rented farm at 14. Training under Benjamin Graham gave him a method. Running investment partnerships in Omaha made him a millionaire by his early 30s. What turned millions into billions was a failing New England textile mill he took over in 1965. Buffett used Berkshire Hathaway’s cash, and later the float from its insurance companies, to buy whole businesses and large stakes in companies such as Coca-Cola and American Express. He then left those investments to compound for half a century.

Known as the “Oracle of Omaha,” Buffett built what became the most successful holding company in the world. His personal fortune exceeded $140 billion in early 2026 by Forbes’ estimate. Thousands of shareholders travel to Nebraska each spring for Berkshire’s annual meeting, an event nicknamed “Woodstock for Capitalists.”

Early Life and Education

Warren Edward Buffett was born on August 30, 1930, in Omaha, Nebraska. He was the second of three children of Howard and Leila Buffett and their only son. His father was a stockbroker who later served four terms in the U.S. House of Representatives as a Republican with libertarian leanings. That background put Buffett close to markets from childhood, but the money he first invested was his own.

How Buffett Got His Initial Capital

Buffett’s starting capital came from small businesses he ran as a boy, not from an inheritance or a family stake. He sold soft drinks and delivered newspapers. At 11 he bought his first shares of stock. At 14 he used his savings to buy 40 acres of farmland, which he rented out for a profit. These were modest sums. Their value was that he learned early to treat earnings as capital to be put to work rather than spent.

College and Benjamin Graham

At his father’s urging, Buffett applied to the University of Pennsylvania and was accepted at 16. After two years he transferred to the University of Nebraska and finished his undergraduate degree there. His father then pushed him toward graduate school. Harvard Business School turned him down, and Columbia University accepted him. That rejection shaped his career, because Columbia was where Benjamin Graham taught.

Graham, widely called the father of value investing, taught that a stock has an “intrinsic value” based on the business and assets behind it, and that an investor should buy only when the market price sits well below that value. Buffett absorbed the idea completely.

His career still started slowly. When he graduated, Graham declined to hire him and even advised him to stay away from Wall Street. Graham had been shut out of Wall Street firms himself, which he attributed to antisemitism, and his firm made a practice of hiring Jewish analysts. Buffett went back to Omaha and worked at his father’s brokerage. He married Susan Thompson in 1952 and started a family. About three years after graduation, Graham changed his mind and offered Buffett a job in New York.

From Graham’s Analyst to Omaha Millionaire

Working for Graham let Buffett apply the theory he had studied. Graham’s version of value investing focused on numbers: find a stock trading at a deep discount to the value of its underlying assets, buy it, and sell when the gap closes. Some of these stocks belonged to mediocre or declining businesses. Graham cared about the discount, not the quality.

Buffett wanted to go further. Unlike his mentor, he wanted to judge a company’s management and the competitive advantage of its products, not only its balance sheet. That difference would later define his approach.

In 1956 Buffett returned to Omaha and launched Buffett Associates, the first of his investment partnerships. Friends and family supplied capital, and Buffett earned a share of the gains. The partnerships were the engine of his first fortune. Around 1962, in his early 30s, he was already a millionaire.

In 1959 he met Charlie Munger, a lawyer who became his closest business partner. Their collaboration, which deepened through the 1960s, pushed Buffett’s thinking away from Graham’s “cigar butt” style of squeezing the last value out of dying businesses. Munger encouraged buying excellent businesses at fair prices instead of fair businesses at excellent prices.

How Buffett Grew Berkshire Hathaway

Berkshire Hathaway is the main answer to how Warren Buffett went from millions to billions. The company did not create the fortune by itself. It gave Buffett a permanent pool of capital he controlled and could keep reinvesting.

A Classic Graham Bargain

Buffett began buying Berkshire Hathaway shares in 1962. The company was a struggling textile manufacturer losing ground to low-cost competition. What attracted him was the price: the stock traded cheaply compared with its book value and net working capital. That was a textbook Graham setup. In 1965 he acquired a controlling interest.

Shares traded around $8 when Buffett started buying and rose to nearly $20 by the late 1960s, when he took over as CEO. Decades later, a single Class A share would trade for hundreds of thousands of dollars.

Turning a Mill Into a Holding Company

Buffett did not try to rescue the textile business with fresh investment. He used the cash it generated to buy other companies. One of the most important early purchases was National Indemnity, an insurance company.

Insurance gave Buffett something his partnerships never had: float. An insurer collects premiums upfront and pays claims later, sometimes years later. In between, it holds that money. If underwriting is disciplined, the float costs little or nothing, and the insurer can invest it in stocks, bonds and whole businesses. For Buffett, insurance float worked like a large, low-cost source of investable money that grew as the insurance operations grew.

Buffett wound down his investment partnerships by 1969 and offered partners Berkshire Hathaway shares instead of cash. From then on, Berkshire was his main vehicle. He kept acquiring insurance companies as wholly owned subsidiaries, and each one added more float to invest.

Cash-Generating Businesses

In 1972 Berkshire bought See’s Candies. The chocolate maker needed little new capital to grow and threw off steady cash, which Buffett sent back into new investments. See’s became an early example of the type of business he came to prefer: a strong brand customers would pay up for, run by capable managers, needing little reinvestment.

The pattern repeated. Cash from operating businesses and float from insurers funded purchases of more businesses and more shares. Those then produced more cash to invest. Buffett closed the last Berkshire textile mill in 1985 but kept the name. By early 2026, Berkshire owned more than 60 companies outright, and its market value had passed $1 trillion.

Buffett’s Investing Strategy

Buffett’s method can be stated simply. Buy shares of well-managed businesses with durable competitive advantages when they are available at a discount to what they are worth. Then hold them indefinitely.

What He Looks For

• An economic moat. A brand, cost advantage or market position that protects profits from competitors.
• Strong, shareholder-minded management. People who run the business well and treat owners fairly.
• High profit margins and solid fundamentals. A business that earns good returns on the capital it uses.
• A sensible price. Even a great company is a poor investment if he overpays for it.

Coca-Cola and American Express met these tests and have stayed in Berkshire’s portfolio for decades. Other major stock holdings over the years have included Bank of America and Apple.

Owning Businesses Outright

Much of Berkshire’s value comes from companies it owns entirely rather than stocks it holds. Buffett usually kept existing management in place and let them run day-to-day operations. His reasoning was straightforward: those managers had already built the business that made it attractive. Well-known names Berkshire has owned or held major stakes in include GEICO, See’s Candies, Dairy Queen, Fruit of the Loom, Pampered Chef and Kraft Heinz.

This hands-off model mattered for his wealth. Buffett did not have to run dozens of companies himself. His main job was allocating capital: deciding where Berkshire’s cash should go next.

Standing Aside From the Tech Bubble

Buffett’s discipline was tested in the late 1990s. He refused to invest in technology companies he did not understand or that did not meet his criteria, and he sat out the run-up in tech stocks. Critics on Wall Street said his approach was outdated.

Then the dotcom bubble burst. Many of the investors who had chased tech stocks suffered heavy losses, while Buffett’s profits doubled. The episode strengthened his reputation as an investor who would accept looking foolish in the short run rather than abandon his rules. His stance on technology softened in later years, which eventually led to Berkshire’s large position in Apple.

Buying When Others Panic

The other side of that discipline is a willingness to buy when markets are frightened. During the 2008 financial crisis, Buffett wrote an opinion piece in The New York Times that contained one of his best-known lines: “A simple rule dictates my buying: Be fearful when others are greedy, and be greedy when others are fearful.” He has also written, in his 1996 letter to Berkshire shareholders, “If you aren’t willing to own a stock for ten years, don’t even think about owning it for ten minutes.”

Both quotes reduce to the same rule. Price and value separate when emotions run high, and the patient buyer gets paid for waiting.

Why Time Mattered as Much as Skill

Buffett’s results depend on two things working together: good returns and an extraordinarily long holding period. He started investing at 11 and was still allocating capital in his 90s. That gave his gains about eight decades to compound.

A hypothetical example shows the mechanism. It is not Buffett’s actual record. Suppose an investor puts in $10,000 and earns 20% a year, reinvesting everything, with no withdrawals and ignoring taxes:

• After 10 years: about $62,000
• After 25 years: about $954,000
• After 50 years: about $91 million

The formula is ending value = starting amount × (1 + annual return) ^ years. At a steady rate, the dollar gains in the final decades dwarf those of the early decades, because each year’s return is earned on a much larger base. Interrupt the compounding by cashing out, paying out profits or taking a large loss, and the later, biggest gains never arrive.

Berkshire’s structure supported this. Buffett rarely sold his best holdings, which meant gains were not interrupted by selling and taxes along the way. Berkshire has also generally reinvested its earnings rather than paying them out. And Buffett’s frugal personal life meant he was not pulling money out to fund spending.

Three Reasons Warren Buffett Is Rich

Pulled together, the story comes down to three reasons:

1. A method. Graham’s value investing, refined with Munger toward quality businesses with moats, gave Buffett a repeatable way to find investments worth more than their price.
2. A vehicle. Berkshire Hathaway, fueled by insurance float and cash from wholly owned businesses, gave him a growing, permanent pool of capital to invest.
3. Time. Starting as a child and holding investments for decades let compounding do most of the work.

Which markets made him wealthy? Mostly U.S. stocks and privately acquired U.S. businesses, with insurance at the center. His first real estate deal came early, but stocks and whole companies built the fortune.

Wealth and Philanthropy

Buffett’s answer to what to do with the fortune is to give almost all of it away.

The 2006 Pledge to the Gates Foundation

In June 2006 Buffett announced he would donate the vast majority of his wealth to the Bill & Melinda Gates Foundation. The foundation works on global health, education and other causes. Until then he had planned to leave his fortune to charity after his death. He explained the change simply: “I know what I want to do, and it makes sense to get going.”

The gift is structured in Berkshire Hathaway Class B shares. The pledge to the Gates Foundation totals 10 million shares, delivered in annual installments that each equal 5% of the shares still remaining. The installments continue until Buffett’s death, or until the foundation fails to meet its spending requirement or neither Bill nor Melinda Gates remains actively involved. The first installment, in 2006, was 500,000 shares worth about $1.5 billion.

The Gifts Since Then

Because the gifts are paid in stock, the dollar value of each installment depends on Berkshire’s share price at the time it is made. Several milestones show the scale:

• By June 2022, the foundation’s CEO, Mark Suzman, said Buffett’s contributions since 2006 had totaled more than $36 billion.
• In 2024, Buffett gave 9,930,357 Berkshire shares worth about $4 billion, as reported by The Wall Street Journal. That year he also gave 695,122 shares split evenly among three foundations run by his children, and 993,035 shares to the foundation named for his first wife.
• In June 2025, he donated 12.36 million Class B shares worth about $6 billion, mainly to the Gates Foundation, with additional shares going to four family foundations.
• In November 2025, he gave roughly $1.35 billion in Class B shares to the four family foundations.

Earlier Giving and the Giving Pledge

Buffett’s philanthropy started long before 2006. For more than 50 years he gave through the Buffett Foundation, later renamed the Susan Thompson Buffett Foundation, which funds college scholarships for low-income students in Nebraska.

He also co-founded The Giving Pledge with Bill and Melinda Gates. Signers commit to giving away the majority of their wealth, and Buffett has encouraged other billionaires to join. His view of inherited fortunes is blunt. As he told BBC News in 2006: “I am not an enthusiast of dynastic wealth, particularly when the alternative is six billion people having much poorer hands in life than we have, having a chance to benefit from the money.”

Personal Life

Despite his wealth, Buffett is famously frugal. He still lives in the five-bedroom Omaha house he bought in 1958 for $31,500. He drinks Coca-Cola, a company Berkshire owns a large stake in, and eats at local restaurants, where his usual order is a burger or a steak.

For years he criticized corporate jets as a waste of shareholder money. When Berkshire finally bought one, he named it the Indefensible, acknowledging his own earlier criticism.

Buffett married Susan Thompson in 1952. They had three children: Susie, Howard and Peter. The couple separated in 1977 but stayed married until Susan’s death in 2004. She introduced him to Astrid Menks, who began living with Buffett in 1978. Buffett and Menks married in August 2006.

His low spending is not only a personality trait. Every dollar he did not spend stayed invested in Berkshire, compounding alongside the rest of his stake.

Legacy

Buffett is widely regarded as one of the greatest investors of all time. As chairman and CEO, he turned a small, failing mill into one of the largest conglomerates in the United States. He also kept leading the company into his 90s. He designated Greg Abel, a longtime Berkshire executive, as his successor as CEO.

His influence reaches well beyond Berkshire. His version of value investing, which means buying strong businesses below their worth and holding them for the long term, is now a standard strategy for individual and professional investors. His annual shareholder letters, written in plain language, have taught generations of readers how he thinks about businesses, management and risk. He sits alongside figures such as Benjamin Graham and Peter Lynch on most lists of the greatest investors of all time. Each of them reached results by a very different route.

Part of his legacy is his character: folksy, plainspoken, modest in his habits despite enormous wealth, and committed to giving his fortune away. The combination of long-term investing, simple living and philanthropy has made him one of the most admired figures in business.

The Bottom Line

Warren Buffett did not get rich from a single bet, a new technology or an inheritance. He started with money he earned as a boy and learned a disciplined method from Benjamin Graham. He built a first fortune through his partnerships, then used Berkshire Hathaway, powered by insurance float and cash from businesses it owned, to keep buying quality companies at sensible prices. Holding those investments for decades let compounding turn millions into well over a hundred billion dollars. Now he is giving the bulk of it away.
