Figures cover domestic political ads paid in dollars, from 4 May 2026. Spend is the sum of Meta’s range midpoints; impressions above one million are reported as “1M+”, so impression figures are floors. Each ad counts in the week its delivery started, with its lifetime spend at our last pull; ads still running before the vote are counted as of 31 October 2026.
