Forbes found at least 100 billionaires in the corners of either former President Donald Trump or Vice President Kamala Harris—with many more backing Harris—but unlike the world’s richest man Elon Musk, who stumps extensively on Trump’s behalf, many have elected to watch from the sidelines, like Warren Buffett and Mark Zuckerberg.

Our breakdown records 83 billionaires supporting Harris and 52 backing Trump so far (see the lists for both below).

Many more billionaires may still financially back a candidate, but their donations won’t be learned until after the election, when final Federal Election Commission reports are issued in December.

Billionaires leaning toward Harris may seem incongruous, since she often criticizes Trump for advocating for policies favorable toward billionaires—but there are practical reasons why the ultra wealthy may favor Harris.

A letter signed by more than a dozen billionaires last month endorsing Harris explained their belief Harris “will continue to advance fair and predictable policies that support the rule of law, stability, and a sound business environment,” indicating the support for the status quo as the U.S. economy and stock market exhibit strength, while a recent survey of millionaire investors—which found a 57% to 43% split in Harris’s favor—identified technology, healthcare and sustainability stocks as the sectors most poised to benefit from a Harris win, a mix friendly to many of her billionaire backers from Silicon Valley, who grew familiar with Harris during her time as a California prosecutor.

Forbes will update this list through Election Day.

Jeff Bezos: The Amazon founder and world’s fourth-richest man wrote Trump “showed tremendous grace and courage under literal fire” following the assassination attempt at a July 13 rally, but Bezos has not endorsed or financially backed, even though he has publicly warred with Trump during his presidency. He celebrated Biden’s election in 2020 with an Instagram post noting the Biden win indicated “unity, empathy, and decency are not characteristics of a bygone era.”

UPDATE (Oct. 29): In a strongly worded editorial in the Bezos-owned Washington Post, the centibillionaire explained his decision to reportedly strike down the newspaper’s endorsement of Harris amid a storm of controversy, explaining he believed it would help restore the public’s faith in the paper’s journalism. “Presidential endorsements do nothing to tip the scales of an election,” wrote Bezos.

Ken Griffin: Griffin (Citadel) confirmed he has not financially backed Trump, adding he’s “torn” and won’t vote with a “smile on my face” as both candidates aren’t “going to receive an award for the quality of their policies” or “the quality of their leadership.”
