Held in New York City on September 30, 2025—fittingly on International Podcast Day—this year’s IAB Podcast Upfront brought together advertisers, publishers, and tech leaders to spotlight the evolving power of podcasting. The sessions made one thing clear: podcasts are no longer a niche medium – they’re a full-fledged marketing engine.
Here are the four biggest themes marketers should take away:
1. Podcasts Are a Trusted and Influential Medium
Podcasting has emerged as one of the most authentic influencer platforms. Whether it’s major media personalities or independent creators, listeners trust their favorite hosts – and that trust translates into brand impact.

🧠 Takeaway: Podcasting is redefining influence. Unlike traditional influencer platforms, podcasts thrive on authentic connections.
2. Audience Growth and Cultural Connection
Podcast audiences are expanding rapidly—especially among Black, Latino, and multicultural listeners. New focuses from publishers, such as sports and female-driven content, are creating new ways for brands to connect with loyal and diverse communities.

3. Podcasts Are Expanding Beyond RSS
Podcasts today are more than just audio—they’re multi-platform content hubs. Creators are extending their reach through YouTube, social media, newsletters, and even branded shows, giving advertisers more ways to engage.
- Jomboy Media showed how podcasts are part of a larger creator-driven ecosystem.

🌐 Takeaway: Think 360 – take advantage of all that podcasts have to offer to fully reach their loyal audiences.
4. Measurement, Performance, and Full-Funnel Impact
Podcast advertising is now measurable and effective across the entire marketing funnel – from awareness to conversion and loyalty.
- Data from Sounds Profitable showed that podcast ads support every stage of the funnel.
