Warren Buffett, worth around $160 billion in 2025, still lives in the Omaha home he bought in 1958 for $31,500. Modest by billionaire standards, the five-bedroom house is now valued at $1.3 million. Despite his wealth, Buffett is famously frugal — driving himself to McDonald’s and once using a flip phone well past its prime. In stark contrast, Sultan Hassanal Bolkiah of Brunei lives in Istana Nurul Iman, a $3 billion palace with 1,788 rooms, 257 bathrooms, and air-conditioned stables for 200 polo ponies. His collection includes over 7,000 luxury cars, and he reportedly once flew his barber in from London for $20,000. While the sultan showcases wealth through extravagance, Buffett invests in simplicity and plans to give most of his fortune to charity. In the world of billionaires, he proves you don’t need a palace to be king. #brunei
