What You'll Learn

Billionaires backing Harris
According to Forbes, Kamala Harris has the backing of more billionaires than former President Donald Trump. Harris has the support of 83 billionaires, while Trump has 52. This includes 28 billionaires who have donated $1 million to Harris since August. Some notable billionaire supporters of Harris include:
- Former Republican governor of California, Schwarzenegger
- Former Meta Platforms executive, Sheryl Sandberg
- Founder of Bloomberg, Michael Bloomberg
- Hollywood director, Steven Spielberg
- Shark Tank judge and philanthropist, Mark Cuban
- Microsoft co-founder, Bill Gates
- Founder of Bridgewater Associates, Ray Dalio
- Google co-founder, Sergey Brin
Despite this show of support from billionaires, Harris has also faced criticism from some ultra-wealthy individuals for her stance on taxing the super-rich. Mark Cuban, for example, has spoken out against the potential of Harris taxing unrealized capital gains.
In addition to billionaire backers, Harris has also raised significant funds from small donors, bringing in over $1 billion since entering the presidential race in July. This war chest has allowed her to outspend Trump, with nearly three times the expenditure.

Small donors
The Harris campaign's ability to attract small donors has been a key factor in her fundraising success, setting her apart from her competitor, Donald Trump. In contrast, Trump's campaign relied more heavily on large donors, with 31% of his funds coming from small donors as of 2024. Harris's success in tapping into a broad base of small donors demonstrates her appeal to a wide range of supporters and reflects the energy and enthusiasm of her grassroots supporters.
While the exact definition of a "small donor" may vary, it generally refers to individuals who make relatively modest contributions to political campaigns. These donors often contribute through online platforms and may be motivated by a particular candidate's policies, personality, or values. Small donors can make a significant collective impact, as evidenced by their crucial role in powering Harris's campaign.
The support from small donors has not only provided financial resources but also helped generate momentum and build a dedicated volunteer base for the Harris campaign. This grassroots support is invaluable in getting out the vote, especially in competitive states, and can translate into a formidable ground game on election day. The enthusiasm of small donors can also create a sense of momentum and attract additional attention and support for a campaign.

Non-profit donations
The League of Conservation Voters, an environmental advocacy non-profit, has contributed $42.5 million, reflecting the importance Harris' campaign places on addressing climate change and environmental issues. American Bridge, a Democratic-aligned non-profit, has injected $36.2 million into Harris' campaign efforts, demonstrating the broad support she enjoys within the Democratic Party. These non-profit donations have been crucial in bolstering Harris' financial resources and enabling her to compete effectively in the presidential race.
It is worth noting that non-profit donations are not solely responsible for Harris' war chest. Her campaign has also attracted significant contributions from prominent individuals and companies. One notable individual donor is Dustin Moskovitz, the co-founder of Facebook, who has invested $38.9 million in Harris' campaign, highlighting the tech sector's interest in her candidacy. Michael Bloomberg, the former mayor of New York City, has also demonstrated his support for Harris by initially donating $47.4 million and then increasing his contribution by an additional $50 million, bringing his overall financial backing for Democratic causes to a substantial amount.
The presence of non-profit donations in political campaigns is indicative of the diverse sources of funding that candidates can tap into. These organizations often align themselves with specific parties or candidates whose values and policies they support. By contributing financial resources, they aim to advance their ideological goals and influence the political landscape. However, it is important to consider the potential implications of such donations on the independence of candidates and the potential for perceived or actual conflicts of interest.

Tech sector support
Kamala Harris has received significant financial support from the tech sector during her political campaigns. While companies themselves are prohibited by law from directly donating to federal campaigns, including presidential ones, their employees are not. As a result, Harris has received substantial donations from workers in the tech industry, particularly from large US tech companies.
Employees of Alphabet (the parent company of Google, Waymo, and YouTube) have donated the most to Harris's campaign, with a total of $2.2 million contributed directly by staff, according to OpenSecrets. This includes donations from immediate family members of employees. Meta (formerly Facebook) and Apple employees have also shown strong support, with donations totalling $835,000 and $861,000 respectively, as of August 21, 2024. Microsoft, Amazon, and Walmart workers have also contributed significantly to Harris's campaign funds, with donations in the millions.
Billionaires in the tech sector have also shown their support for Harris. While some have not officially endorsed a candidate, their positive comments and large donations indicate their backing. For example, French Gates, the ex-wife of Microsoft co-founder Bill Gates, reportedly donated $13 million to Harris groups, and Gates himself allegedly donated $50 million to the non-profit wing of a Democratic political action committee supporting Harris. Jeff Bezos, the founder of Amazon, has also been identified as one of Harris's prominent backers.
In addition to individual contributions, Harris has benefited from donations to pro-Harris political action committees (PACs). Future Forward USA, a pro-Harris PAC, has raised more than $200 million. This demonstrates the significant financial support Harris has received from the tech sector, both directly and indirectly, during her political campaigns.
