With voting already underway in nearly half of the U.S., the contest for control of the Senate is expanding into states that many analysts had not expected to become central battlegrounds. The broader map is pushing both parties to increase campaign outlays in a midterm cycle that is on track to become the most expensive election in American history.
Highlights
- Estimated $11.6 billion has been spent so far on the U.S. Senate race, already surpassing total 2024 presidential race spending.
- A widening Senate battleground map is drawing resources into more states than expected, amplifying late campaign fundraising and spending pressure for both parties.
- Surging advertising and fundraising reflects intense competition for chamber control, positioning 2024 to set a new record for overall U.S. election costs.

We also noted that persistently elevated yields would raise federal borrowing costs and complicate debt management, adding pressure to the broader cost-of-living and fiscal backdrop.
