Audible is pouring money into Originals as Spotify takes a growing share of the audiobook market. These two differing approaches raise the question: is the real innovation in audio coming from original content, original ways of accessing content, or both?

Three years ago, Spotify put 15 hours of audiobooks into every UK Premium subscription, and plenty of people wondered whether the music app could really sell books. That question has been robustly answered. The more interesting one now is what Audible, still the dominant player for English-language listeners, is doing about it.

On the surface, the answer is Originals. In November 2025, Audible released the first of its full-cast Harry Potter editions: more than 200 actors, an immersive soundscape, a new instalment every month until May. This year, nearly 200 former Wondery+ podcast titles followed, rebadged as Audible Originals when Amazon closed the Wondery app. It’s an impressive amount of activity.

But Spotify has been innovating too, just not in the same place. Audible is betting on content: things you can only hear in one place, as well as newly developed AI-tools that allow listeners to interact with characters in the books; another kind of original content. Spotify is betting on access: new ways to find, pay for and move between books. The numbers suggest only one of those bets is actually changing how people listen, and genuinely bringing new listeners to the format.

At last month’s Frankfurt Book Fair, Spotify said monthly audiobook listeners had grown by nearly 40% in a year, and claimed roughly 20% of the US market. Its Audiobooks+ add-on has passed $100m in annual recurring revenue, and by the end of the year Spotify audiobooks will be in more than 180 markets, up from 22. Most telling of all, almost half its audiobook listeners started in the past 12 months, many of them new to the format.

Almost none of that growth comes from exclusive content. It comes from product decisions: putting audiobooks where people already listen, metering by the hour rather than the title, and selling extra time rather than a whole new subscription.Then there’s Page Match, which lets readers scan a printed book and pick up at the same point in the audio; more than a million people have used it since February. None of this is especially glamorous; instead, it is a genuine rethink of how people come to audiobooks.

It isn’t perfect (15 hours with no rollover sounds generous until you start a 30-hour fantasy novel), but it is a model built around new listeners, and it’s finding them.

Spotify isn’t without content ambitions of its own. Its podcast push was built on acquisitions and exclusives, starting with Gimlet, and its first audiobook experiments were exclusive celebrity readings of classics. Audiobooks proper began with the 2021 purchase of distributor Findaway, and its in-house imprint, Spotify Audiobooks, has struck some exclusive deals with publishers. But exclusivity is not the pitch. As it expands to 180 markets, Spotify is stressing that its partnerships with authors and publishers are non-exclusive. For publishers, that is the difference between a partner and a competitor. Audible’s Originals, meanwhile, are a more mixed picture, and they come in at least three kinds.

When the same badge covers a 200-actor Harry Potter, a Lisa Jewell thriller and a repackaged history podcast, it stops guiding listeners and starts meaning, simply, “available here”

The first is the big adaptation. Harry Potter is a genuine bet on what audio can do that print cannot. It treats the audiobook as a production in its own right, with all the investment and ambition that implies. That’s distinctive, good for the format, and when it works, it genuinely moves the goalposts of what people expect from audiobooks. The second, like the Wondery migration, is something else: a podcast library relabelled, at the end of a restructure that cost around 110 jobs. It makes Audible bigger, but it is less clear whether it makes Audible better.

The third kind, arguably the most interesting, is the one most likely to make Audible better: stories written for the ear first, with no print edition behind them. James Patterson has been writing full-cast audio thrillers for Audible since 2021, from The Coldest Case to Trapped. Lisa Jewell’s first, All She Wants for Christmas, arrives this month narrated by Matthew Rhys, Ruth Wilson and Phoebe Dynevor, and will be released simultaneously in four other languages. Nor is audio-first a niche: in the US, it grew 50% to $136m in 2025, about 6% of the market. It is where the stakes for publishers are highest: new work by bestselling authors, exclusive to one platform.

But it shares a badge with everything else, which points to a bigger problem. As a label, ‘Audible Original’ doesn’t stand for anything consistent. It isn’t a mark of taste, scale or production quality, even though plenty of Originals have all three in spades. HBO means something in television; A24 means something in film. When the same badge covers a 200-actor Harry Potter, a Lisa Jewell thriller and a repackaged history podcast, it stops guiding listeners and starts meaning, simply, “available here”.

Audible has made product moves too, though more cautiously: a cheaper Standard plan pairing a monthly credit with a curated set of Originals, and a deal putting around 700 Originals inside Apple Podcasts. Both make a lot of sense, but neither move fundamentally changes how people discover or pay for books the way Spotify’s moves have. The monthly credit at Audible’s heart looks much as it always has.

Perhaps that doesn’t matter yet. Listeners seem to be stacking rather than switching: when Spotify added audiobooks to Premium in Sweden, it barely moved daily listener numbers, and most people listening on Spotify also used another service.

But publishers should be paying attention to the difference. Content-led innovation means platforms making their own exclusives, competing with publishers’ titles for listening hours, credits and homepage space. Access-led innovation brings new listeners to the whole catalogue, though it raises questions of its own (what does an hourly meter mean for long, ambitious books?).

At their best, Originals show what audio can be. However, the biggest shifts in listening over the past three years have come not from what people hear but from how easily people can find it, pay for it and pick it up.

The real prize will go to whoever combines the two: Originals worth seeking out, on a service that is easy to fall into. For now, Audible has more of the former and Spotify more of the latter. Which will master the other’s trick first, and which will be the most beneficial to publishing partners, agents, authors and, crucially, listeners?
