Consumers spend a lot of time listening to their favorite content these days. This means marketers have more opportunity to reach them. How does the ad-supported audio market break out? And how do podcast advertisements connect with consumers? New research on the ad market and on the podcast listening audience answers these questions.
How Consumer Audio Time is Spent
The average U.S. adult listens to content for 3 hours and 53 minutes a day. In Q3 2025, around 64% of the content was ad supported. Edison and Nielsen Research points out that the ad-supported listening time breaks out across the following formats:
- Radio 62%
- Podcasts 20%
- Ad supported streaming music 15%
- Ad supported satellite radio channels 3%
Advertiser Spending on Podcasts
As podcasts attract more listeners, producers are taking in more ad money. Total spending in the U.S. this year will likely amount to $3B. And not surprisingly, the demand typically increases in Q4 as marketers seek to connect with their target audience during the holiday season.
Podcasting continues to attract new advertisers according to Magellan data. Compared to 2024, Q3 2025 advertising in podcasts was up 26% for the companies tracked by Magellan.
Industries that are shifting ad spend to podcasts include gaming and dating. Those categories spend less, in total, than other fast-growing verticals such as phone and internet and food. However, the industries that spend the most on podcasts are financial services and consumer/services and software.
Spending Data by Podcast Size
A significant portion of podcast ads, 48%, goes to the top 500 programs. The top podcasts generate about $355K a month from an advertiser. In the next tier, podcasts in the 501 to 3000 level, in terms of audience, attract $40K per month from an advertiser.
While a large amount of spending is snapped up by the most popular podcasts, you also have the opportunity to sell the ad space to newcomers who are targeting niche audiences. Over 1,600 brands new to podcasting used the format in Q3 2025.
Ad Loads
Your accounts may be curious about ad loads in podcasts. It’s natural to worry that the message might be lost by too many ads in one program. Currently, around 8.34% in the programming time goes to ads, nearly the same as in Q3 2024. The most popular shows, the Top 500, have the highest ad load at 9.1%
Ad loads also vary by program type. Genres with the highest ad load include true crime (13.48%) and society and culture (10.68%). True crime is having a moment and is one of the most popular types of podcast programming. Around 26% of U.S. adults enjoy listening to true crime content according AudienceSCAN from AdMall.
The sports category carries an ad load of 8.15%. 23% of U.S adults tune into this type of audio programming. However, sports programming is one of the most popular for marketers. Magellan reports that 20% of new brands on podcasts opted to run ads on sports programs.
The second most popular category for new podcast advertisers was the comedy genre. This tactic suggests that big brands are seeking to connect with a broad audience.
The researchers found variations in ad load with respect to episode length. Shorter podcasts have a higher ad load. Programs with less than 15 minutes of content have an average of 20% ad content. Longer programs, over 60 minutes, average a 6.7% ad load.
Ad Types
Around 41% of podcast ads are direct response. By making a specific offer, marketers can measure the impact of their ad investment in a podcast. Otherwise, podcast ad formats are brand awareness (56%) and tune-in (3%).
Podcast advertisers continue to favor an ad length of 30 seconds. And 55% seek the mid-roll placement, which is understandable. Consumers may be less likely to stop listening to a podcast once they’re invested in the content. And they’ll be willing to hear an ad.
They also have options about ad production and insertion. In Q3, 46% of ads were host-read as the episode is produced. In general, listeners pay attention to products pitched by the program hosts.
26% were produced in advance and inserted after the podcast is produced. 32% are inserted programmatically.
Some marketers are taking no chances regarding their chance to make an impression on listeners. The technology, education and business genres were the highest in terms of having a single advertiser running through the content. Overall, about 5% of podcast episodes had one advertiser.
Targeting Podcast Ad Respondents
AudienceSCAN contains the data you need to help your accounts target podcast ad responders. Around 25% of U.S. adults fall into this category. Roughly 40% of this audience listens to podcasts for up to an hour a day. Another 29% listen between 1 and 3 hours a day.
They over-index for personal interest in video games (30%) and fashion (21%). If your clients are selling these kinds of products, podcast ads could deliver big results.
Podcast advertisements are growing in their ability to influence consumers. Don't let your clients ignore this important media format.
