AI-generated ‘podslop’ now accounts for 39% of new podcasts

A torrent of AI-generated podcasts is overwhelming listening platforms, with new data showing that nearly four in ten new shows added to podcast directories over a recent nine-day period were likely created by artificial intelligence. The phenomenon, dubbed "podslop," is forcing the audio industry to confront a spam crisis it was not prepared for.

The Scale of the Problem

According to the Podcast Index, an open-source platform that tracks the podcast ecosystem, approximately 4,243 of the roughly 10,871 new podcast feeds created over a nine-day span — about 39% — were likely AI-generated. Bloomberg reporter Ashley Carman, who first reported on the trend, described the surge as outpacing the industry's ability to set rules around it.gizmodo+3

The Podcast Index data also revealed that a single publisher, Inception Point AI, released 325 new shows in a single day, accounting for nearly one in five of all new podcasts submitted that day. Many of these AI-created shows are being uploaded to multiple platforms, with Spreaker by iHeartRadio iHeartMedia, Inc. ↗ 3.32% identified as a primary host. The shows cover an eclectic range of topics and languages, from a Portuguese-language biography of Bruno Mars to wellness advice about walking 10,000 steps daily.podnews+2

Platform Responses Lag Behind

The economics driving podslop are straightforward: networks using generative AI tools can produce thousands of episodes per week for as little as one dollar per episode, according to an analysis by Podcast Videos. The content is designed to capture search traffic and programmatic advertising revenue with minimal human involvement.podcastvideos

Platform defenses remain uneven. Spreaker now displays a notification when its system identifies a podcast as AI-generated. Spotify ↗ 3.31% recently introduced a "Verified by Spotify" badge to help listeners identify authentic human creators, though AI-generated content remains permitted on the platform. The Podcast Index has launched a new API endpoint that flags shows marked as spam, phishing, or "low-effort AI," which hosting companies and apps can use to curate their feeds.inc+2

An Uncertain Future for Discovery

For listeners, the flood of automated content is making discovery increasingly difficult. As Podnews reported in mid-April, legitimate human-made podcasts had already become a minority among new submissions, with only 44.6% of new shows classified as "likely legitimate" in a single 24-hour period. The trend raises questions about whether platforms can maintain trust without more aggressive intervention — and whether the open podcast ecosystem, long celebrated for its low barriers to entry, can survive the onslaught of machine-generated content without fundamentally changing how new shows reach audiences.podnews
