Streaming TV is the fastest-growing political ad channel for 2026
AdImpact forecasts record political ad spending for the 2026 election, with streaming TV as the fastest-growing channel, while broadcast remains dominant. Roku and Magnite released new ad tech insights, with Magnite launching 'Magnite Orchestration' to leverage AI-driven campaign workflows for media buyers. Gray Media is also partnering with Madhive to boost local TV campaigns with Madhive's ad planning and measurement tools.
Key Takeaways
- AdImpact projects record $11.6 billion in 2026 political ad spend, surpassing 2024's $11.2 billion.
- Streaming TV's share of political spend is expected to reach 23% this cycle.
- Magnite launched 'Magnite Orchestration' to integrate AI-driven agentic workflows for media buyers.
- Roku and Omnicom report that combining home screen and video ads increases ad recall by 61%.
- Gray Media is partnering with Madhive to deploy AI-driven ad planning and measurement for local TV.
Why It Matters
The shift toward streaming for political advertising indicates that digital targeting has become essential for high-stakes outreach, even as broadcast retains its reach-based dominance. For the tech stack, the launch of Magnite Orchestration and Gray Media’s Madhive partnership signal a move toward 'agentic' advertising, where AI handles complex multi-channel workflows. This automation is no longer experimental; it is being used to capture local and political budgets that require rapid, data-driven optimization. Watch for 2026 CPM trends in battleground states like California and Texas as programmatic streaming inventory faces unprecedented competition during the fall window.
Additional Context
The 2026 midterm cycle is projected to be the most expensive non-presidential election in U.S. history. Per AdImpact in June 2026, the updated $11.6 billion forecast represents a significant jump from the $8.9 billion spent during the 2022 midterms. This surge is fueled by high-stakes Senate and gubernatorial races in states like California, where the gubernatorial primary has already become the most expensive on record. While broadcast television has seen its estimated spend revised upward to $5.6 billion, its overall dominance is softening as campaigns increasingly favor the precision of connected TV (CTV) to reach cord-cutters. AdImpact reports that CTV is the only channel projected to consistently grow its share compared to original 2024 figures. Technological shifts toward 'agentic' advertising are accelerating to meet this demand. Per Magnite's June 2026 announcement, its new Orchestration layer is already being tested by major partners including dentsu and DirecTV Advertising. This system allows AI-driven ‘buyer agents’ to negotiate directly with ‘seller agents,’ effectively automating the matching of proprietary audience data with premium inventory. This mirrors broader industry moves toward interoperable AI standards, such as the Advertising Context Protocol (AdCP) adopted by other major SSPs earlier in the year. For local broadcasters like Gray Media, adopting Madhive’s Maverick AI provides the technical parity needed to compete with digital-native platforms for the estimated $1.6 billion in digital political spend flowing through Meta and Google this year.
