Podcast advertising keeps growing faster than digital advertising broadly: US podcast ad revenue reached $2.9 billion in 2025 and is on track for $3.0 billion in 2026, up 17.6% year over year, according to IAB and PwC figures aggregated by Libsyn — and the IAB has now raised its 2026 outlook further.

The Interactive Advertising Bureau lifted its full-year US ad spending forecast to 12.3% growth after a stronger-than-expected first half, with podcast ad spending projected to rise 8.7% — ahead of paid search, digital out-of-home, digital display and gaming, per Inside Audio Marketing and Podcast News Daily. Podcasts are growing at more than twice the rate of other digital audio, which is forecast at 3.6%.

The infrastructure story matters for creators. Dynamic ad insertion now accounts for 74% of all podcast ad impressions, unlocking programmatic buying and attribution at scale. The top 10 podcast networks command roughly 60% of industry ad revenue, per Edison Research — concentration that favors creators inside networks with shared ad delivery and reporting.

Globally, estimates vary by methodology: EMARKETER forecasts put worldwide podcast ad spending as high as $28.6 billion in 2026, while other analyses land lower. What is consistent across sources is the direction — podcasting accounts for 34% of all US digital audio ad revenue and keeps taking share.

For creators, the practical read is that podcast advertising has matured from a reach buy into a measurable performance channel, which is exactly what unlocks bigger brand budgets.

The takeaway for creators: if you run a podcast, make sure your hosting supports dynamic ad insertion — it is how 74% of podcast ads now transact. And consider video: Spotify and YouTube are both paying for video podcasts, giving one recording session two revenue streams.
