Warren Buffett

Buffett's wealth is almost entirely tied to his 16% stake in Berkshire Hathaway, the conglomerate he's run since 1965. What makes this extraordinary is that he built this fortune through compound interest and patient value investing, not flashy tech IPOs or crypto speculation. Berkshire's Class A shares trade at around $540,000 each—making it the most expensive stock on major exchanges—because Buffett refuses to split the stock, believing it attracts long-term investors over day traders.

The genius of Buffett's wealth accumulation lies in Berkshire's structure as both an investment vehicle and operating company. It owns massive stakes in Apple ($174 billion), Coca-Cola, and American Express, while also fully owning profitable businesses like GEICO insurance and BNSF Railway. This dual approach generates both capital gains and steady cash flow, which Berkshire reinvests rather than paying dividends. The result: $1,000 invested in Berkshire in 1965 would be worth over $30 million today.

What's remarkable about Buffett's spending habits is how little they've changed despite his astronomical wealth. He still works from a modest office in Omaha, famously orders the same breakfast from McDonald's based on stock market performance, and has given away over $50 billion to charity since 2006 through the Giving Pledge. His annual salary from Berkshire is just $100,000—proving that when you own the casino, you don't need to take a big salary from it.
