Spotify's Audiobook Business Is Growing Faster Than Its User Base
Spotify's Audiobook Business Is Growing Faster Than Its User Base
Spotify's audiobook service added users at a 36% annual rate in its second year, while the total hours people spent listening to audiobooks climbed 37% in the same period, according to Bloomberg. That small gap—37% hours versus 36% users—matters. It suggests existing customers are spending more time with audiobooks, rather than just trying them once and moving on.
Spotify Adds a Second Major Content Type
Audiobooks are now Spotify's biggest bet on content beyond music. The company launched the service in October 2022, bundling a modest 15 hours of monthly listening into regular subscription plans, with the option to buy more.
This move echoes Spotify's earlier push into podcasts, which took years, big money, and exclusive deals (like paying for Joe Rogan's show) to establish. But the audiobook strategy has been different: instead of chasing blockbuster personalities, Spotify has focused on building a deep catalog through partnerships with major publishers like Penguin Random House, Macmillan, and HarperCollins.
What the Numbers Suggest About User Behavior
The fact that listening hours are growing slightly faster than the number of users is telling. When a platform moves beyond early adopters into mainstream usage, this kind of pattern typically appears—meaning the average user is listening a bit more, but not dramatically so.
To put this in perspective, Spotify's entire user base grew about 11% year-over-year in recent quarters. That makes 36% growth in audiobook users notably higher. The company is drawing these listeners from two pools: existing music subscribers who are discovering audiobooks on the platform, and potentially new users who signed up mainly for spoken-word content.
The Competitive Terrain
Spotify enters a market where Amazon's Audible already dominates, traditional publishers are launching their own services, and Apple is integrating audiobooks into its ecosystem. But Spotify has a built-in advantage: it bundles audiobooks into existing music subscriptions rather than forcing customers to buy a separate app or sign up for a new service.
The broader context here is that we have seen this movie before. When Netflix bundled films and TV into one subscription, it upended how people expected to consume video. The friction and mental accounting of switching between services—and paying separately for each one—gradually gave way to "just have it included." Spotify appears to be betting the same logic applies to audiobooks.
How Spotify Handles the Technical Side
Spotify's audiobook setup reuses much of the infrastructure already built for music: the same network for delivering files, the same phone optimization, and recommendation algorithms adapted to suggest audiobooks based on what listeners enjoy. The company did have to build new features specific to spoken audio, such as chapter navigation, adjustable playback speed, and bookmarks—capabilities that music streaming didn't require.
Existing Spotify conveniences, like downloading content to listen offline and picking up on another device where you left off, work with audiobooks too.
Different Economics with Publishers
Here is where audiobooks differ significantly from music. Spotify pays musicians based on streaming royalties—essentially a cut per play. With audiobooks, the economics work more like a bookstore. Publishers control pricing and can set time-limited availability, which gives them much more say in the deal than music labels typically have. This shapes Spotify's profit margins differently than music does.
What Comes Next
If this 36% annual growth rate holds steady, Spotify could become a serious player in audiobooks within a couple of years. But audiobook listening works differently than music—people commit to longer sessions and discover content in different ways—so sustained growth cannot be taken for granted.
The upshot of today's numbers is that Spotify's gamble on bundling is working. People who already subscribe for music are trying audiobooks and coming back. Whether that momentum lasts will hinge on Spotify adding more titles, making the experience smoother, and how aggressively Audible and other competitors respond. For now, audiobooks are shifting from Spotify's experimental corner to something that could reshape how the platform thinks about itself.
