Consumers can’t get enough of podcast listening. The media format continues to grow with programs that target niche and general audiences. That growth is also expanding opportunities for your accounts to connect with engaged audiences through podcast advertising.
How Big is the Podcast Market?
The latest research from AudienceSCAN, powered by AdMall, shows that 25% of U.S. adults have taken action in the last month as a result of a podcast ad. Even better, that’s a 26% increase in the number of U.S. adults who took action based on an audio podcast based on year-over-year projections.
And what action are they taking? Among other things, after hearing the ad, 36% of these adults searched with ChatGPT or another AI tool to learn more. The U.S. podcast advertising market reached $2.57 billion in 2024. And this number may rise to $3 billion next year.
What is the Composition of U.S. Podcast Ad Market?
Your accounts may be interested in joining the many other marketers that are investing in podcast advertising. Magellan AI reports a 28% increase in podcast ad spending in Q2 2025, when compared to the same period last year.
What Types of Ads are Popular on Podcasts?
Advertisers like for the hosts to read the promotional or branded content. At least 47% of spending went to host-read ads that ran in Q2 25. About 27% of ad spending went to the “produced” category. Finally, 27% of spending amounted to programmatic or run-of-network placements.
Analysts report that new brands continue to break into podcast advertising. Larger companies spend as much as $42K in a quarter.
What about Ad Placement and Length?
Placement of ads in the content stream matters. Most marketers favor mid-roll ads which makes sense. Listeners are already hooked on the content, and they may be more willing to hear an ad to get to the end of what they’ve been enjoying. In addition, AudienceSCAN data shows that 24% of podcast listeners get annoyed when ads that run before the content last too long.
And since the average ad on a podcast lasts 49 seconds, marketers may not be asking too much. The most popular ad length in podcasting is 30 seconds (35%). Around 13% of the ads are 15 seconds, and 16% last an entire minute.
Overall, the total advertising load for podcasts landed at around 8.13% of the total run time in Q2 2025. That’s a bit lower than the same period last year when the extra 1.07% translated into 39 seconds.
What are the Characteristics of the Podcast Listening Audience?
AudienceSCAN data shows that around 39.5% of podcast ad responders listen to their favorite content for up to an hour a day. This behavior gives your accounts plenty of opportunity to connect with their target audience.
The most popular genres for audio programming, per AudienceSCAN, include:
- Comedy 41%
- Sports talk 35%
- True crime 34%
These categories match the data Magellan AI reveals. Specifically, listeners hear more advertising on specific types of podcasts. True crime (8.3%), education (7.75%) and kids and family (7.75%) categories are in demand by marketers.
What are the popular genres for new brands in podcasting? For 20%, it’s sports. That compares to 13% for news.
In addition, these consumers are vastly more open to non-advertising influence in the form of a mention on a podcast. 58% of the listening audience takes action based on that kind of a mention. If your accounts work with the host or podcast program manager to weave in a discussion of their product or service, they will be noticed.
What Type of Messaging Influences Podcast Listeners?
These consumers are far more likely than average to look for products that help them feel popular, prestigious and rugged/tough. Your accounts should focus on that type of messaging to sell more products.
If your accounts are advertising events, a message on a podcast might make a big impact. 27% of podcast listeners expect to go to a music festival in the next year, while 20% will do some sipping at a beer/wine festival.
Conclusion
Podcast advertising is one more way for your accounts to connect with their target audience. Talk with them about the best ways to include the format in their media buying plans.
