Spending on the 2026 US midterm election campaign is projected to reach nearly $12bn, according to an assessment examining the scale and sources of funding behind the contest.
The forecast would make the campaign the most expensive US midterm election campaign ever, with spending described as breaking existing records. The figure covers the wider campaign period and highlights the substantial sums expected to be committed to the election.
An investigation is examining where the money behind the campaign has come from. The supplied reporting does not provide a detailed breakdown of the donors, organisations or types of spending involved, but indicates that the scale of funding is central to understanding the projected total.
The 2026 midterms are therefore on course to set a new financial benchmark for US congressional elections. Further details about the sources of the money and how it is being spent are expected to clarify the forces driving the record projection.
