Who Are the Billionaires Backing Trump or Harris? Bloomberg dug into its Billionaire Index to find out which candidates the super-wealthy are supporting.

If you are a registered voter, there is a very good chance that you are besieged on a daily basis by texts and emails from campaign fundraisers begging you for money. As annoying as it is, it works. In the first full month of her candidacy, Vice President Kamala Harris's campaign announced it raised $361 million from nearly 3 million donors. Former President Donald Trump's team says he raised $130 million over the same period and had $327 million going into August.

That's a lot of money coming in from a lot of sources. And one of those sources is billionaires. Bloomberg's Kristine Owram and Bill Allison used Federal Election Commission data as of August to find members of the Bloomberg Billionaires Index who've donated to the Harris or Trump campaigns. They also included some billionaires like Elon Musk and Bill Ackman who "don't show up in the FEC data but have endorsed one of the candidates."
