Musk breaks donor record as the ultrarich pour $2.7 billion into the midterms
Billionaires and Elon Musk, who recently temporarily achieved trillionaire status, make up the top individual donors.
Elon Musk has cemented his record as the largest individual political donor in modern American history. The world’s richest man poured $446 million of his own money into this year’s midterm elections, mostly aimed at preserving the Republican Party’s control of Congress, recent election filings show.
While Musk and the other largest donors this cycle lean heavily Republican, former New York mayor Mike Bloomberg also sprang onto the scene. Since September, Bloomberg has given $60 million, largely to back House Democrats, according to Federal Election Commission filings.
Musk’s spending alleviated the fears of some Republicans who worried the Tesla CEO would not come to their rescue after a dramatic and public feud with President Donald Trump last year. Musk gave at least $355 million to his super PAC and other Republican-aligned groups since the start of July, according to FEC filings this month.
In total, the top donors in American politics have poured in more than $2.7 billion to influence the midterm elections.
Republicans are hoping the influx of cash will help them in the final stretch before November by blanketing the airwaves and deploying more canvassers to voters’ doors. Republican-leaning donors gave $1.7 billion, compared with $832 million from Democratic-leaning givers and $264 million from bipartisan and special-interest groups, such as those backing sports betting and cryptocurrency interests.
Most of the money, regardless of affiliation, was given to super PACs that can legally accept unlimited sums.
Top individual donors
Musk is one of four individual donors who has given more than $100 million to influence the midterm elections. Three of the four mainly back Republican candidates.
In some cases, individual contributors donate to political action committees through companies they own rather than under their own name. For example, billionaire Democratic donor George Soros is the owner of Geosor and the Fund for Policy Reform, which together gave $102 million in the first six months of the cycle.
(Washington Post owner Jeff Bezos, one of the world’s wealthiest people, has donated just $15,000 this cycle, all of it to federal committees affiliated with companies Amazon and Blue Origin.)
Trillionaire technology executive
Musk, the world’s richest person, is the CEO of Tesla and SpaceX. In 2025, he led the Trump administration’s efforts to reshape the federal goverment through the U.S. DOGE Service.
Shipping magnates
The couple owns Uline, a Wisconsin-based shipping and packaging materials company. They donate to the GOP and to further right causes, supporting antiabortion and anti-LGBTQ+ groups.
Financier and education advocate
Jeff co-founded the Pennsylvania-based investment company Susquehanna International Group. His wife, Janine, founded a Philadelphia charter school and is an advocate for school choice.
Billionaire investor and philanthropist
Liberal billionaire and philanthropist George Soros donated through both the company Geosor and the nonprofit Fund for Policy Reform. The groups have given to PACs backing Democrats in federal and state elections.
Venture capitalists
Marc Andreesen and Ben Horowitz are co-founders and partners of the venture capital firm that bears their initials. Their firm has largely given to pro-tech and pro-crypto super PACs like Fairshake.
Former mayor of New York
Bloomberg is co-founder of the financial software and media company that bears his name. He served as mayor of New York for three terms and ran for president in 2020.
Physician and widow of businessman Sheldon Adelson
Adelson, a doctor who has focused on addiction, is the majority shareholder of Las Vegas Sands, a casino company, and a majority owner of the Dallas Mavericks NBA team. A pro-Israel donor, Adelson gave massive amounts of money to support all of Trump’s presidential bids.
Cryptocurrency billionaire brothers
The twin brothers, who claimed Mark Zuckerberg stole the idea for Facebook from them, co-founded a cryptocurrency exchange and an investment firm that bears their name.
Hedge fund manager and activist investor
The billionaire is founder and co-CEO of Elliott Management, an investment management firm headquartered in Florida.
OpenAI president and co-founder, wife
The couple have given to Donald Trump and the pro-AI PAC Leading the Future.
Top 10 organizations
Individual donors pumped the most money into this cycle, but a variety of groups also weighed in with big donations.
The list includes organizations that are focused on advancing a cause rather than being affiliated with a political party. Among them are the cryptocurrency companies Coinbase and Ripple, along with sports gambling companies and the powerful American Israel Public Affairs Committee.

About this story
The Washington Post analyzed contributions to federal political committees since Jan. 1, 2025, covering donations reported to the Federal Election Commission as of Oct. 23, 2026. Direct independent expenditures, loans, refunds, bank payments such as interest and dividends, and contributions from a candidate to their own campaign are not included. Donations made by federal political action committees are not part of the list of top donors. Giving from some individuals includes donations from organizations controlled by them. Groups that gave to support candidates from both parties, or gave largely to nonpartisan PACs, are marked as “special interest.” If individuals endorsed President Donald Trump, they are marked as Republican. This tally will be updated periodically.
