Billionaire Elon Musk has cemented his position as the largest individual political donor in modern American history after spending $446 million of his personal fortune on the 2026 US midterm elections, as the country’s 50 biggest donors collectively contribute more than $2.7 billion to influence the contests.
According to an analysis by The Washington Post, the world’s richest man has directed most of his political spending towards helping the Republican Party retain control of Congress in the November elections.
The newspaper reported that the 50 biggest donors have contributed a combined $2.77 billion during the 2026 midterm election cycle, highlighting the growing financial influence of billionaires and wealthy interest groups in American politics.
Republican-leaning donors contributed approximately $1.7 billion, compared with $832 million from Democratic-leaning donors and $264 million from bipartisan and special-interest groups.
Musk’s spending represents the largest individual contribution recorded in modern American political history, with at least $355 million going to his super political action committee and other Republican-aligned groups since the beginning of July.
The donations also mark a significant return to large-scale political spending by Musk following his public falling-out with President Donald Trump last year, which raised concerns among Republicans about whether the billionaire would continue supporting their candidates.
Musk, the chief executive of Tesla and SpaceX, has channelled substantial sums into organisations supporting Republican candidates for the Senate and House of Representatives.
According to The Washington Post, his largest disclosed contributions include nearly $216 million to America PAC, the political action committee he backs, $168 million to the Senate Leadership Fund and $30 million to the Congressional Leadership Fund.
The Senate Leadership Fund supports Republican Senate candidates, while the Congressional Leadership Fund backs Republican candidates seeking election to the House of Representatives.
Musk’s contributions have also supported the closely contested Texas Senate race, where Republican candidate and state Attorney General Ken Paxton is facing Democratic challenger James Talarico.
The billionaire previously contributed $158 million to the Senate Leadership Fund through two donations in September, according to campaign finance filings cited in earlier reports.
He also donated $10 million to the pro-Paxton Lone Star Liberty PAC, further demonstrating his financial commitment to Republican efforts in the state.
His America PAC has also supported Republican candidates in competitive congressional races.
While Republican-leaning donors dominate the overall spending, wealthy Democratic supporters have also contributed substantial sums to influence the midterm elections.
Former New York mayor Mike Bloomberg has donated $60 million since September, largely to support Democratic candidates seeking election to the House of Representatives, according to The Washington Post.
Billionaire Democratic donor George Soros has also channelled money through organisations he owns. Geosor and the Fund for Policy Reform together contributed $102 million during the first six months of the election cycle.
The newspaper noted that four individual donors have each contributed more than $100 million to influence the midterm elections, with three primarily supporting Republican candidates.
Beyond individual billionaires, the list of major contributors includes cryptocurrency companies, sports betting businesses, the American Israel Public Affairs Committee and nonprofit organisations that can fund political groups without publicly disclosing their donors.
Much of the money has gone to super PACs, which can legally accept unlimited contributions to finance independent political activities supporting or opposing candidates.
The financial surge comes as Republicans seek to retain their majorities in Congress, with the November 3 elections expected to shape the remainder of Trump’s presidency and determine the prospects for his legislative agenda.
Republicans are hoping the influx of money will help them reach voters through extensive advertising campaigns and ground operations, including canvassing and other mobilisation efforts.
The elections are taking place amid economic concerns and declining approval ratings for the administration.
The Wall Street Journal reported in September that Trump’s approval rating had fallen to 37 per cent in its polling, a low for a president heading into midterm elections in the publication’s polling history dating back to 1990.
With more than $2.7 billion already contributed by the 50 biggest donors, the scale of political spending underscores the central role wealthy individuals and organisations are playing in the battle for control of Congress.
