Born: 1930
Net worth: US$147.7 billion
Nationality: American
Nicknamed the “Oracle of Omaha,” Warren Buffett is widely regarded as one of the most successful investors in history. His advice is closely followed in business circles, perhaps best summarized by his famous maxim: “Be fearful when others are greedy, and greedy when others are fearful.”
Buffett currently serves as chairman of Berkshire Hathaway, a massive conglomerate that owns dozens of subsidiaries, ranging from insurance giant GEICO and battery maker Duracell to the ice cream chain Dairy Queen. After six decades at the helm, he recently stepped down as CEO at the start of this year, handing over the reins to his successor, Greg Abel.
Beyond his wealth and investment acumen, Buffett is known for his immense philanthropy. He has pledged to donate 99% of his fortune to charitable causes and has already given away roughly $65 billion.

Born: 1930
Net worth: $7.4 billion
Nationality: American
George Soros left Hungary at age 17 for London, where he supported himself as a waiter and railway porter to fund his studies at the London School of Economics. After graduating, he persistently wrote letters to merchant bank executives until he finally landed a job in finance.
Soros later relocated to New York and founded his own massively successful hedge fund, Soros Fund Management. He managed client assets for decades before returning outside investors’ money in 2011 to run the firm as a family office. However, he remains best known in the financial world for famously shorting the British pound during the 1992 Black Wednesday crisis. That legendary trade earned him $1 billion in a single day, forever branding him as “the man who broke the Bank of England.”

Born: 1930
Net worth: $2.3 billion
Nationality: British
Former Formula One executive Bernie Ecclestone was born to a fisherman’s family in Suffolk, England. Showing an early entrepreneurial spirit, he delivered newspapers before school and resold snacks to classmates for a profit.
He left school at 16 to work at a local gasworks while pursuing a passion for motorcycles, eventually opening a successful dealership. Though his own stint driving in Formula One in the late 1950s was brief, Ecclestone found his true calling in management. He purchased the Brabham F1 team in 1972 and, by 1978, had taken control of the Formula One Constructors’ Association.
In the decades that followed, Ecclestone revolutionized the sport. He secured massive television and advertising deals, transforming Formula One into a lucrative, globally licensed brand by 1997. His wealth skyrocketed, and he reached billionaire status around 2005 after selling shares in the Formula One Group. In January 2017, Ecclestone finally stepped down as chief executive after the sport was sold to Liberty Media.

Born: 1966
Net worth: $9.1 billion
Nationality: Russian
Orphaned as a toddler, Roman Abramovich was raised by relatives before eventually dropping out of college to pursue business. He built his massive fortune following the collapse of the Soviet Union through investments in major Russian companies, including the oil firm Sibneft, mining giant Norilsk Nickel, and steelmaker Evraz.
Following the outbreak of the Russia-Ukraine war, Abramovich reportedly served as an early intermediary in peace negotiations and helped facilitate high-profile prisoner exchanges.
He is perhaps best known globally as the former owner of Chelsea F.C. Following U.K. sanctions in 2022, he was forced to sell the club to a consortium led by American billionaire Todd Boehly in a deal worth over $5 billion. However, the estimated £2.5 billion (roughly $3.1 billion) in proceeds earmarked for victims of the war remain locked in a frozen U.K. bank account, with the British government recently threatening court action to force the transfer of the funds.

Justin Sun’s career and public persona are deeply intertwined with the cryptocurrency industry. He began his journey into digital assets in 2012 by investing in Bitcoin while studying at the University of Pennsylvania.

Today, TRON consistently ranks among the world’s top cryptocurrencies, currently sitting in the number eight spot with a market capitalization of roughly $26.4 billion, according to CoinMarketCap.
Beyond his blockchain ventures, Sun is notorious for leveraging his vast wealth for high-profile stunts. In 2019, he paid $4.57 million at a charity auction to win a private lunch with investment legend Warren Buffett.
More recently, in November 2024, Sun made international waves when he purchased “Comedian”, Maurizio Cattelan’s infamous duct-taped banana artwork, at Sotheby’s for $6.24 million, before eating the fruit on stage at a press conference as promised.
