Senate & House · 2014–2026

Past Performances

Four midterms on one scale, in 2026 dollars. 2026 Senate races have drawn $2.5B so far, against $3B for all of 2022 — but outside groups now supply 58% of it, up from 37%. 2026 is still in progress, so its columns will grow; at the same point in 2022, Senate races had drawn $1.9B, and on past midterms' pace 2026 would finish around $3.8B–$4B.

At the same point in the race

The totals above compare 2026 so far with finished cycles. Here each past midterm is cut off at the same point in the year: campaign spending through Sept 30, outside spending through the date of 2026's newest filing. The dashed bar and bracket project 2026's final total if money keeps arriving at a past midterm's pace. It's an estimate, not a record.

Dashed segment, open dot: 2026 to date (not final)

Lines join each state's midterm Senate races; a state with no race in a cycle skips it. Most seats up in 2026 were last contested in 2020 and, before that, in 2014. Only states with a 2026 race are shown.

Limits of this data

Candidate totals come from each campaign's most recent filed report; most cover through June 30 or September 30, so recent fundraising is not yet visible.

Outside spending in House special elections is left out of race totals (listed under Exclusions). A candidate who also ran in a 2025–26 House special still has that campaign's own spending in their FEC totals, which cover the whole two-year cycle and can't be split.

Comparing an in-progress cycle to completed ones understates 2026; the 'same point' bars and the projected range correct for that, but the projection is an estimate, not a forecast of record. Outside money has grown faster than campaign money in each recent cycle, and late money in 2026 could break the past pattern.

Some 2026 campaigns' newest report covers through June 30 rather than Sept 30, so 2026's campaign total (and its projection) may be slightly low until those reports are processed.
