Warren Buffett built his fortune largely through investment via his holding company Berkshire Hathaway Inc., accumulating large, long‐term stakes in companies across industries (insurance, utilities, consumer goods, etc.). Known as “the Oracle of Omaha,” his disciplined value-investing approach over many decades has yielded massive returns. Buffett’s wealth is tied to the stock and assets of Berkshire Hathaway, and though he is older and less active in daily operations, his legacy investments continue to underpin his billionaire status.
