At a glance:
What changed: The Court overturned caps on coordinated spending, letting party committees spend unlimited amounts in direct coordination with candidates, including on advertising.
Who's affected: Broadcast stations and cable systems that sell political advertising, along with the committees and candidates now able to access more LUR-priced coordinated buys.
For broadcasters: Expect more spending to shift into LUR-priced inventory, compressing effective rates and adding pressure on inventory during peak windows.
For digital and DSP buyers: Coordinated dollars are likely to stay in broadcast in the near term, since LUR is available on broadcast stations and cable systems, making those outlets more cost-efficient for committees, not less. However, inventory constraints in competitive markets could push some marginal spend into CTV/OTT and digital as budgets outpace available inventory.
On June 30th, the Supreme Court handed down its opinion in NRSC v. FEC, eliminating the limits on how much political parties can spend in direct coordination with their own candidates. Those limits had held most House races to $65.3K and the largest Senate contests to roughly $4M. The ruling is likely to reshape not just party fundraising strategy, but how broadcasters and media buyers plan for the 2026 midterms and beyond, as committees gain new access to pricing that had long been reserved for candidates.
With the decision, committees can now spend unlimited sums coordinating directly with candidates on all advertising. Crucially, those coordinated buys access candidates' lowest unit rate (LUR) pricing, the FCC rule that guarantees candidates the cheapest ad rate a station offers any advertiser. That pricing applies 45 days before a primary and 60 days before a general election. Previously, any spending beyond the coordination cap had to run as Independent Expenditure advertising, which stations could price at market rates rather than LUR.
Party committees and campaigns had already been working to circumvent the coordination caps prior to the decision through hybrid advertising, which allows a candidate and party to promote themselves generically in the same spot and split the cost. In 2024, AdImpact calculated hybrid advertising accounted for $198M in broadcast spending, and committees spent another $140M on non-coordinated advertising, together making up roughly 7% of that cycle's overall broadcast spending. With coordination caps gone, both the $140M in non-coordinated spending and the $198M in hybrid spending would have qualified for LUR-priced buys.
That doesn't necessarily mean all of that spending stays in broadcast. LUR access makes coordinated broadcast buys more cost-efficient for committees, not less, which argues for holding or even increasing their share of broadcast rather than shrinking it. But if inventory is exhausted in competitive markets before budgets, the marginal dollar has nowhere to go in linear and could spill into CTV, OTT, or digital. This isn't a certain structural reallocation, but it's a real possibility, particularly in the roughly 10 states expected to account for half of all political spending this cycle.
Pricing is only half the issue; broadcast inventory is a fixed constraint that will also shape how this plays out. Every station has a set number of spots per daypart, and that number doesn't grow just because more buyers show up. If committees now need more spots to reach the same spending levels, those spots come out of the same inventory that issue advertisers and core commercial advertisers rely on. As dayparts sell out, lower-priced spots get preempted first, pushing the effective rate floor higher.
Core advertisers may feel this squeeze the most. They compete for the same inventory as political campaigns, often in the same high-value dayparts: local news, primetime, and other high-visibility slots. As LUR-priced coordinated buys take up more of that inventory, less is left over for commercial advertisers, and what is available will be more expensive than in prior political cycles. We'll follow up separately with a closer look at what this means specifically for core advertisers as the picture develops.
Candidates themselves aren't insulated from this either. LUR is calculated off a station's lowest unit charge for any comparable spot, and that floor rises with demand. As more coordinated spending competes for the same LUR-priced inventory, the effective floor rises, meaning candidates could end up paying more for LUR access than in prior cycles.
For broadcasters and media buyers, the practical work starts now. Mapping DMA-level exposure to competitive House and Senate races, stress-testing Q4 rate flexibility, and reviewing rate card assumptions ahead of the fall will matter more this year than in a typical midterm cycle. Whatever the long-term political implications of this ruling, its most immediate impact is on supply, pricing, and inventory management, a hard operational reality that broadcasters and buyers need to plan around before political spending actually arrives in the weeks leading up to Election Day.
