Ten Donors Have Put $1 Billion Into the 2026 Midterms
Ten megadonors have spent a total of $1 billion on the 2026 midterm elections, according to MarketWatch, which reported the figure on November 2, 2026. The tally is one thread in a cycle that NBC News has described as the most expensive election cycle ever. A cycle is the full run of federal races in a two-year period, and midterms are the congressional elections held halfway through a president's term. The same NBC report identifies the Texas Senate contest between Republican Ken Paxton and Democrat James Talarico as the most expensive race of 2026.
The spending is not spread evenly across races. OpenSecrets reported in October that more than $170 million had poured into Florida's governor's race between Byron Donalds and David Jolly. Party committees and outside groups account for much of the rest. Outside groups are organizations that spend independently of candidates' campaigns. Bloomberg reported on October 29 that the Republican Party and three super PACs, which are independent groups that can raise unlimited sums, tied to Trump or to House and Senate leaders had raised $2.1 billion. Raised and spent are different measures, and the two should not be read as interchangeable.
Individual giving is where the concentration is sharpest. Firstpost estimates that Elon Musk is the biggest known donor in the 2026 midterms, with giving between roughly $366 million and $446 million.
For a historical anchor, OpenSecrets lists Musk as the top individual federal contributor in the 2023-2024 cycle, at $291,482,587 in contributions. Timothy Mellon ranked second among individuals in the 2024 cycle, with $197,047,200.
Outside spending has been climbing for several cycles. OpenSecrets put outside spending on the 2022 federal midterms above $2 billion. In 2024, OpenSecrets projected total federal election spending of at least $15.9 billion, which it said put that cycle on track to be the costliest ever. A Wall Street Journal headline dated October 31, 2026 described the current contest as a $12 billion election.
The Federal Election Commission's data give a different angle. Its statistical summary of 18-month campaign activity for the 2025-2026 cycle, published October 1, 2026, reported total receipts (money coming in) of $864.3 million, disbursements (money going out) of $614.2 million, debts of $40.6 million and cash on hand of $379.4 million. The FEC's FY27 congressional budget justification says the reports it received contained 502.7 million transactions, disclosing $28.3 billion in receipts and $28.0 billion in disbursements.
The practical point for anyone tracking this is the gap between what is raised, what is spent, what is owed and what remains on hand. The FEC's 18-month numbers show committees carrying debts and cash balances that will shape late-cycle spending, and outside-group totals capture money that may never pass through a candidate's committee. A $1 billion figure from ten donors is therefore best read as a measure of concentration, not of total cycle cost. The filings that will settle the 2026 totals are still arriving.
