iHeart Dominates Podcast Rankings as Stuff You Should Know Becomes No. 1
The U.S. podcasting landscape saw a notable reshuffle in March as fresh data from Triton Digital revealed both stability at the top and surprising movement across key rankings. While iHeartMedia continued to dominate overall audience reach through its iHeart Audience Network, a new leader emerged in the highly competitive podcast chart: the long-running educational show Stuff You Should Know.
The latest report underscores a dynamic and rapidly evolving podcast ecosystem—one shaped by global news cycles, audience preferences, and the growing influence of international publishers entering the U.S. market.
Despite growing competition, iHeart’s podcast empire shows no signs of slowing down. According to Triton Digital’s March report, the iHeart Audience Network secured its position as the most-listened-to podcast network in the United States, delivering an impressive 71.5 million average weekly downloads.
That figure represents a modest but meaningful 1% increase from February, reinforcing iHeart’s consistent upward trajectory in a crowded marketplace.
Key Highlights of iHeart’s Performance:
71.5 million weekly downloads in March
Maintained No. 1 ranking among podcast networks
Continued growth despite saturation in the podcast market
Industry analysts suggest that iHeart’s sustained success stems from its diversified content strategy, robust distribution infrastructure, and strong advertiser relationships.
Audioboom and Cumulus Hold Their Ground
Trailing iHeart—but still firmly positioned—are two established players:
Audioboom retained its No. 2 position with 16.3 million average weekly downloads, though it experienced a slight dip compared to the previous month.
Cumulus Media maintained third place, reporting 3.6 million downloads, essentially unchanged from February.
What This Means for the Market:
The top three networks remain largely unchanged, signaling stability
Growth margins are narrowing, indicating a maturing podcast ecosystem
Mid-tier and emerging networks are increasingly challenging incumbents
New Entrants Shake Up the Rankings
March also marked the entry of new global voices into Triton’s measurement ecosystem—bringing diversity and fresh competition.
