Podcasting’s Next Growth Frontier: Tackling the Unconverted

Key Takeaways

• 25% of U.S. adults never listen to podcasts.
• Global non‑listener data reveals a sizable untapped market.
• MIDiA will map demographics and habits of unconverted listeners in 2026.
• Industry must shift research from engaged to disengaged audiences.
• Targeting non‑listeners could raise overall podcast ad spend.

Pulse Analysis

The podcast ecosystem has matured rapidly, with global downloads surpassing 2 billion per month and ad revenue projected to exceed $2 billion in 2025. Yet MIDiA’s latest ‘2025 Audio Consumer Profile’ uncovers a paradox: roughly one‑quarter of U.S. adults—and a comparable share worldwide—have never pressed play on a podcast. This ‘unconverted’ cohort represents a silent majority that traditional metrics ignore. While platform wars and listener‑centric analytics have driven incremental gains, the next wave of expansion hinges on converting these dormant users rather than squeezing more value from the already‑engaged.

Understanding why people stay silent is the first hurdle. Surveys point to low awareness of podcast libraries, perceived time constraints, and a belief that content is niche or irrelevant. Unlike streaming music, podcasts lack a single, universally recognized storefront, making discovery more fragmented. Moreover, older demographics often associate audio with radio rather than on‑demand storytelling. By overlaying non‑listener data with media consumption habits—such as streaming video, social feeds, and audiobook usage—researchers can pinpoint crossover moments where a podcast introduction feels natural.

From a commercial perspective, unlocking the unconverted could swell the addressable market by an estimated $500 million in annual ad spend, according to industry models. Brands will need to craft entry‑point campaigns that leverage familiar channels—short‑form video, influencer snippets, or bundled audio‑visual experiences—to lower the activation barrier. Platforms, meanwhile, should enrich recommendation engines with cross‑media signals and experiment with free‑trial bundles tied to popular non‑podcast content. As MIDiA’s 2026 research rolls out, the data will guide a strategic pivot that transforms a silent segment into a growth engine for the entire audio ecosystem.
