Podcast advertising is heading through the second half of 2026 with strong momentum. According to Magellan AI, podcast ad spend was up 28% year over year in Q1 and 23% in Q2. That builds on a record 2025, when US podcast ad revenue grew 17.6% to $2.86 billion, according to IAB, outpacing digital advertising overall by 27%. Advertisers waiting for a better time to grow their podcast budgets are sitting out one of the category’s strongest stretches.

The audience base is no longer a bet

Edison Research’s 2026 Infinite Dial report puts monthly US podcast listening at a record 58% of Americans aged 12 and up, about 167 million people. Weekly listening has reached 45%, about 130 million. That kind of reach once took broadcast to secure. Podcasts pair it with the focused, opt-in attention listeners give the shows they choose.

Brands are moving in, and the top shows are filling up

Magellan AI counted 1,318 brands advertising on podcasts for the first time in Q1 2026 and 1,297 more in Q2. Brand-awareness campaigns grew to 59% of podcast ad spend in Q2, a sign that advertisers are using podcasts for more than performance goals. Spend is also concentrating: the top 500 shows took 52% of Q2 ad dollars, up from 48% in Q1, so the most sought-after inventory is getting more competitive.

Attention is still underpriced

According to IAB, podcasts capture nearly 5% of all time spent with digital media. That’s a big share for one format when digital media includes social platforms, streaming video, websites, apps, and gaming. Yet podcasts receive less than 1% of digital ad spending. When a channel holds far more attention than it earns in ad dollars, that gap rarely lasts. Early movers tend to secure access and rates that late arrivals can’t.

Why we’re telling clients to move now

At Media Manager, we’re treating H2 2026 as a window to act, not a checkpoint to wait out. Spend grew by double digits year over year in both quarters of H1, new brands are entering at a steady pace, and dollars are concentrating on the top shows. We help clients secure strong placements now, before rising demand makes them harder to get.

The category has already proven itself. The open question is how much of it a brand claims before the rest of the market catches up.
