Podcast advertising hit its strongest month of the year in March, with Q1 2026 seeing a 21% increase in spend year-over-year. This comes as 2025 saw a 32% increase in ad spending for the entire year.

New data from Podscribe shows the top 10 podcast advertisers spent a combined $45.6 million in March, the highest monthly total of 2026 so far. Genre targeting remains consistent with prior months. Sports podcasts continue to attract a disproportionate share of large-brand spending — while Comedy and Society & Culture remain core categories for brands deploying more host-driven campaigns. Brand awareness continued to make up a majority (58%) of podcast ad spend in the US during the first quarter quarter, compared to 40% for direct response and the remaining 2% for tune-in.

With a full quarter now complete, the takeaway is less about who is spending the most, and more about how. Q1 also reinforced a growing divide in strategy. Some brands are clearly using podcasting as a reach medium, deploying multi-million-dollar budgets across more than 1,000 shows with lower host-read reliance. Others continue concentrating similar dollar levels into fewer shows with host-read shares often exceeding 80%. Increasingly, a third group is emerging in the middle — blending both approaches.
