Leading the newcomers, with a $30.4 billion fortune, is Miriam Adelson, wife of the late casino mogul Sheldon Adelson, who died in January at age 87. She and her late husband have been among the biggest backers of the Republican party; in the 2020 elections they gave $180 million to political action committees and Republican candidates’ campaigns. At age 75, Adelson isn’t the eldest newcomer in 2021: That distinction goes to 80-year-old Robert Brockman, the secretive billionaire software investor who has been charged by the U.S. government with directing the biggest tax-evasion scheme in American history; he’s pleaded not guilty. After deducting $1.3 billion of his assets that have been frozen, Forbes estimates his net worth at $4.7 billion.
The youngest newcomer is 29-year-old cryptocurrency billionaire Sam Bankman-Fried, who is the second-richest new entrant, with an estimated $22.5 billion fortune. Close behind in age—if not net worth—are fellow crypto entrepreneurs Brian Armstrong ($11.5 billion) and Fred Ehrsam ($3.5 billion), cofounders of crypto exchange Coinbase, and Baiju Bhatt ($2.9 billion), cofounder of stock trading app Robinhood Markets. Outside of finance and tech, the next largest cohort of newcomers is from the healthcare industry, including Li Ge of Shanghai-based medical devices maker Wuxi AppTec ($11.6 billion) and a trio of backers and executives of vaccine maker Moderna: early investor and Harvard professor Timothy Springer ($5.9 billion), Moderna’s cofounder and chairman Noubar Afeyan ($5 billion) and cofounder and MIT professor Robert Langer ($4.9 billion).
Another notable newcomer is philanthropist Melinda French Gates, the co-chair of the Bill and Melinda Gates Foundation, who now has an independent fortune worth an estimated $6.3 billion after the couple announced their divorce in early May. Rounding out the 44 new entrants are the billionaire twin brothers and crypto entrepreneurs Cameron and Tyler Winklevoss, who fittingly graced the first cover of Forbes magazine to be turned into a non-fungible token in April.
