Ohio's $422.6 Million Senate Race Leads the General Election — Texas Leads a Different Count

Ohio's Senate race has drawn $422.6 million in total spending in the general election, more than any other contest in 2026. That ranking comes from MarketWatch, which identified data centers as a crucial issue in the contest.
The Democratic candidate in that race is Sherrod Brown. Brown raised $23.1 million in donations in the third quarter of 2026 — July through September — according to Morningstar. Separate local tracking also calls Ohio the most expensive Senate race in the country. That account puts campaign ad spending in the race at more than $4 million, per Spectrum News.
Texas is larger on a different cut. The Texas Senate race accounted for $500 million in combined ad spending and future reservations — ads booked ahead but not yet aired — dating back to the primaries, according to AdImpact data cited by The Hill. It is like comparing only the final game to the whole season. Ohio leads on general-election spending, meaning only the final matchup. Texas leads when primary outlays and booked future inventory are included.
At the cycle level, midterm ad spending has topped $10 billion, per The New York Times. AdImpact projects the 2026 election cycle will reach $11.6 billion in political ad spending, a record. That June projection still anchors October coverage. An earlier-cycle tracker had put 2025-2026 political ad spending at $10.8 billion, up more than 20% from 2022, per AdImpact. OpenSecrets noted in January that the 2026 elections were on track to become the most expensive midterm elections.
Energy policy is part of the pricing. Bloomberg reported on Oct. 16, 2026 that blowback against data centers has become a top issue in the 2026 midterm elections, per Bloomberg. The U.S. Senate blocked legislation to address data center costs that would have required state utility regulators to consider large electricity users, according to Reuters reporting from Sept. 30, 2026.
The broader context here is measurement mismatch and cost allocation. Total race spending, booked ad reservations, and realized ad spend do not map one to one. Reservations inflate early totals. Fundraising quarters lag disbursement, or actual payment. General-election universes diverge from full-cycle universes that include primaries. For media owners, the $11.6 billion print is forward-booked revenue. For campaigns, it is working-capital drag into higher fourth-quarter rates. For utilities, the Senate vote leaves large-load cost questions inside state regulatory proceedings.
Looking at what this means for tracking, watch revisions rather than headlines. AdImpact's June projection holding into October suggests inventory was pre-booked and pricing held firm. The Texas-Ohio gap is a definitional spread. Close it by separating primaries, general election, reservations, and independent expenditures. Brown's $23.1 million third quarter reads as cash conversion to fund late-cycle buys, not as vote share. In my view, the durable issue for markets is regulatory dispersion. Without a federal screen for large-user costs, decisions stay commission by commission. That dispersion will surface in power contracts and project timelines before it surfaces in polls.
