The gains were across the board, though no one saw a bigger jump than Elon Musk, who was worth $137 billion on Jan. 2, 2023, and now stands at $229 billion, according to Bloomberg’s Billionaires Index. Close behind him in terms of gains was Meta founder Mark Zuckerberg, who jumped from $45.6 billion to $128 billion.

Even billionaires giving away their fortunes saw their net worth increase substantially. Warren Buffett, who gave away $5 billion of his wealth in June of last year and another $870 million in November, is currently worth $13 billion more than he was on Jan. 2, 2023.
