Context:

Projected to reach a record $11.6 billion, the U.S. midterm ad spend signals a sustained surge driven by highly competitive Senate and gubernatorial races in Ohio, Texas, and Maine. Spending is concentrated in a small set of swing contests expected to decide control of Congress, with Republicans defending slim majorities and Democrats aiming to retake the House. The rise follows a pattern of elevated investment in pivotal battlegrounds, outpacing prior cycles and underscoring both high-stakes incumbency battles and national political headwinds. The forward outlook suggests continued heavy advertising until election day as key races intensify.
