On the first night of the Democratic National Convention, Joe Biden passed the torch to Kamala Harris. It came with a bunch of billionaire backers.

During a speech about her economic policy plans in August, newly minted Democratic nominee Kamala Harris attacked Donald Trump for supporting tax cuts for the wealthy. “If you want to know who someone cares about, look [at] who they fight for,” she told the Raleigh, North Carolina crowd. “Donald Trump fights for billionaires and large corporations. I will fight to give money back to working- and middle-class Americans.” Even as she tries to claim the economic populism mantle, though, her campaign is bankrolled by plenty of billionaires.

Forbes last examined the top Democratic megadonors funding Joe Biden’s struggling reelection campaign in June, using filings through the end of May. Since then, the top ten’s total donations have jumped by nearly $10 million through the end of July, according to the most up-to-date federal filings. And plenty more billionaires have opened their pockets for Democrats: We now count 28 billionaires, with a total net worth of $280 billion, who have given more than $1 million to groups supporting the Democratic presidential nominee.

Biden’s fundraising apparatus, and all the money he had raised, passed to Harris shortly after the president dropped out on July 21, meaning that his donors became her donors. And while the Harris campaign and Democratic groups reported a tsunami of cash in the days and weeks following the candidate swap, because some groups’ filings cover through the end of June and others through the end of July—when Harris had been the candidate for just nine days—it remains to be seen just how much this group of megadonors shelled out for her specifically. And, more importantly, how much more they might give to her than they would have given to Biden.

As of right now, former New York City mayor Michael Bloomberg and LinkedIn cofounder Reid Hoffman still lead the pack, with more than $20 million a piece to various groups backing the vice president. That includes around $3 million from each doled out in the last two months on record. Additionally, former Google CEO Eric Schmidt has now surged into the top 10. Other newcomers include hospitality magnate John Pritzker, whose cousin J.B. Pritzker is the Democratic governor of Illinois, and hedge funder Tom Steyer, who ran for the Democratic nomination in 2020. Half of the 28 live in California; all but four—including Oklahoman Lynn Schusterman and Coloradan Pat Stryker—live in a coastal state.

The billionaires’ cash, $116 million in all, is still nearly 10% less than the $125 million given to Trump-backing groups by a single billionaire, Timothy Mellon, not to mention the other 25 billionaires who have backed his campaign. It’s also only a bit more than the $72 million that a single nonprofit called Future Forward USA Action has given to a super PAC backing Harris. Thanks to its tax status, though, FF USA Action doesn’t have to disclose its donors, a list that, if public, would almost certainly include even more billionaires.

Donation figures listed are the sum of contributions to groups that have supported Biden—and, thus, Harris—as of the most recent filings.

Donations: $23.7 million, up from $20 million

Net worth: $104.7 billion

Bloomberg blew more than $1 billion on his own campaign in 2020, got knocked out, then threw his weight behind Biden, contributing over $100 million to groups that backed him. This cycle, he donated $19 million to Biden’s (now Harris’s) main super PAC at the end of May. Bloomberg’s cash isn’t limited to the top of the ballot, though—he sent $10 million to the main PAC backing House Democrats in July. The former mayor of New York City, who got rich selling data-packed machines to virtually everyone on Wall Street, has given billions to charitable organizations. Yet his fortune continues to balloon—Bloomberg entered the exclusive $100 billion club earlier this year.

Donations: $20.8 million, up from $17.7 million

A venture capitalist with Greylock Partners, Hoffman cofounded PayPal with Elon Musk and Peter Thiel before starting LinkedIn, which he sold to Microsoft for $26 billion in 2016. While other members of the “PayPal mafia” have drifted to the right in recent years, Hoffman has become one of the nation’s biggest Democratic donors. He has already poured more than $40 million into left-leaning groups since 2020, with nearly half of that going to groups now supporting Harris. After Biden dropped out, Hoffman penned an op-ed in The New York Times urging Silicon Valley to get behind Harris: “A Harris administration would greatly benefit every American, and every American business, by having a president who has dedicated her career to upholding the rule of law rather than upending it.”

Donations: $10.6 million, up from $10.2 million

Net worth: $31.4 billion

Simons left his position in Stony Brook University’s math department to start the pioneering quantitative trading firm Renaissance Technologies. He died on May 10 at 86, survived by his wife Marilyn. The couple had been liberal donors for decades, and Jim continued to give major sums in the last months of his life, including a $6.6 million donation to then-Biden’s super PAC just a week before he died. Together, the pair have contributed a combined $10.6 million to the election effort.

Donations: $8.8 million, up from $8.3 million
