YouTube vs podcast CPM

The short answer
One side of this comparison has a published rate card and the other does not. Baked-in podcast host-reads average $18 to $22 (30 seconds) and $24 to $26 (60 seconds) per thousand downloads on Libsyn Ads' published rates (formerly AdvertiseCast, retrieved October 2026); YouTube publishes no advertiser rates and clears through the Google Ads auction. Worse for tidy comparisons: the two channels do not even count the same event.
The denominator caveat, upfront
A podcast thousand is 1,000 IAB-filtered downloads: delivery, not confirmed listening. A YouTube thousand is 1,000 served impressions, or view-charged events under CPV billing's 30-second rule. Neither denominator maps onto the other, so a naive rate-versus-rate line would compare files fetched against pixels rendered. Any comparison that skips this footnote is decorating with numbers.
What a $2,500 sponsor budget does on each
- Podcast: at $18 to $26 CPM across both spot lengths, $2,500 buys host-read coverage of 96,154 to 138,889 downloads, delivered inside shows whose hosts endorse you. The worked buy is at the mid-roll scenario.
- YouTube: the same budget enters an auction with no published rate; what it buys depends on format, targeting and season. What is documented is the machinery: formats and billing rules.
Attention shape, not just price
Podcast listening is habitual and completion-heavy: the host-read premium prices borrowed trust. YouTube offers scale, targeting precision and the skip button. Sponsor categories sort accordingly: considered B2B and finance products over-index into podcasts; visual, broad-market and app-install budgets over-index into video (the CPV math). Audio's programmatic lane, priced closer to standard inventory, is at Spotify ads.
