Top Trends in Advertising in Podcasts You Need to Know This Year

How did advertising in podcasts fare in Q4 2025? Magellan AI reports that marketers increased ad spending by 32%, compared to the same period in the previous year. This spending will serve advertisers well. AudienceSCAN data shows that the number of podcast ad responders in the U.S. increased 26% between 2024 and 2025.

What is the volume of podcast ad spending in the U.S.

Analysts believe that total podcast ad spending reached $2.53B in 2025. Further, the spending is likely to rise to $3B by 2028.

As more consumers tune into podcasts, new marketers are entering this media space. Nearly 1,500 new brands invested in podcast advertising for the first time in Q4 2026. Magellan reports. On an individual basis, they allocated $33K to their investment during that time period.

The interest in advertising in podcasts is also leading to more episode time being taken up by marketer messages. Around 8.8% of episode time, the highest it’s ever been, now goes to advertising.

In addition, shorter programs, those under 15 minutes, carry an ad load that amounts to 22% of the episodes. But for programs of 60 minutes or longer, the ad loads total about 7.3% of the total time.

What do all these data points mean for marketers who are considering advertising in podcasts? First, they should know that all podcasts are not created equal. Specifically, marketers must consider reach. 

They should ask how many consumers they can reach with this investment. Podcasts with the largest download volume, the top 500, have snagged 49% of podcast ad spending. The top shows have up to 5,000 downloads within the first seven days after performance.

Targeting audiences by genre

Then there is the topic of podcast genres. Some genres are far more popular than others. When your accounts want to reach a specific audience, advertising on a unique genre podcast makes an impact.

Around 11.37% of total Q4 advertising went to the true crime category. 26% of U.S. adults regularly listen to true crime audio programming, reports AudienceSCAN.

This audience ranks high in intent to switch their internet provider and their mobile/wireless provider in the coming year. In addition, around 32% of this audience plans to attend a music festival this year.

Not far behind is society and culture podcasts. This category captures 10.15% of advertising.

And when new brands sign on to podcast advertising, around 20% opt to run their messages of sports podcasts. You can reinforce a sale for this type of podcast by letting your account know the latest AudienceSCAN data: 29% of radio/podcast listeners tune into sports play-by-play content. Further, around 9% of U.S. adults identify as sports marketing responders. In the next year, 22% of these adults will be shopping for a new gym/health club.

What are marketers paying for podcast ads?

 Ad costs are levied by downloads. A mid-roll host-read ad will cost a marketer between $15 and $30 CPM. Note that in the Magellan study, about 34% of ads were host-read in Q4 2025. This type of ad can make a big impact on the target audience who often trusts the host.

Another option is programmatic podcast ads. Marketers typically pay from $5 to $15 CPM. These ads are inserted as run of network.

As you sell your podcast media space, pay attention to what your accounts want to achieve.

Podcast ad types break out as follows:

• Direct response 40%
• Brand awareness 58%
• Tune-in (promotional spots highlighting an upcoming show) 2%

The most popular ad length is 30 seconds. And your accounts will likely want to opt for a mid-roll placement to minimize the chances of the target audience skipping their message.

Conclusion

While podcasting is still a new media format, it is increasingly important. For example, around 69% of podcast listeners report learning about new products. When your accounts ask about advertising in podcasts, share the details about reach, cost and target audiences to help them achieve their goals.
