An analysis released Wednesday showed that the United States' 815 billionaires have seen their combined wealth surge by roughly $280 billion since Donald Trump's victory in the 2024 presidential election earlier this month, a finding that came as Republicans continued to lay the groundwork for another massive tax giveaway for the rich. Citing Forbes data, Americans for Tax Fairness (ATF) noted that the collective net worth of the nation's billionaires jumped $276 billion between November 4—the day before Election Day—and November 12.
