What Library Checkout Data Actually Says About the Audiobook Boom

Libraries and their digital lending apps had their biggest year yet in 2025, and the audiobook industry's own sales figures grew right alongside them, which sounds like a single, simple growth story. Look at both sets of numbers together, though, and a more complicated picture appears: demand is real and rising, supply is rising faster still, and the gap between those two trends is exactly where a working narrator's actual prospects live.

OverDrive, which powers the Libby and Sora library apps used by most US public libraries, reported more than 820 million digital checkouts worldwide in 2025, up 10.9 percent over 2024. Audiobooks were the fastest-growing major format inside that total, up 13 percent to 315.9 million checkouts, ahead of ebooks, which grew just 3 percent to 379.4 million. More than 200 library systems, consortia, and school districts topped one million checkouts for the first time in 2025. The prior year told a similar story at an even faster pace: 739 million total checkouts in 2024, up 17 percent over 2023, with audiobooks growing 19 percent that year.

Industry Revenue: Growing, But Slower Than Titles

The Audio Publishers Association's own sales survey, conducted by Edison Research, put US audiobook revenue at $2.43 billion in 2025, up 9 percent year over year, following 13 percent growth in 2024. Growth is decelerating even as the absolute market keeps expanding, and the reason becomes clear in a separate figure from the same data set: publishers reported more than 750,000 active audiobook titles in 2025, a 43 percent increase over 2024, a supply growth rate nearly five times the revenue growth rate in the same period. Industry press has started describing that gap as evidence of a genuine oversupply problem rather than simple, healthy growth.

"The growth in active titles is filling a demand rather than driving additional supply. As the format grows, consumers are looking for all books to be available, backlist and frontlist, and publishers are filling that need."

McManus's framing is the optimistic read of the same gap: more titles because readers now expect anything they might want in print to also exist in audio, not because publishers are flooding the market speculatively. Both things can be true at once. A backlist-completion boom and a genuine oversupply of thin-margin titles produce the same headline number, more titles growing faster than revenue, and the honest takeaway for a working narrator is that more titles being produced does not automatically mean more well-paid work per narrator; it can just as easily mean more titles competing for the same listening hours and the same production budgets.

Who Is Actually Listening, By Two Different Measures

Two credible, well-run surveys describe audiobook listenership using genuinely different measures, and conflating them produces a misleading picture either way. The APA's own 2026 survey, run by Edison Research, found 58 percent of American adults, an estimated 157 million people, have ever listened to an audiobook, up from 51 percent a year earlier. Pew Research Center's separate national survey, fielded in October 2025 and published in April 2026, asked a stricter question, listened to an audiobook in the past 12 months, and found 26 percent, roughly double the rate Pew measured a decade earlier but a much smaller number than the APA's lifetime figure. Both are real and both are useful; they simply answer different questions, one about ever trying the format, one about current, active use.

Buried in the OverDrive data is a detail worth a narrator's attention specifically: children's and YA checkouts rose 9 percent in 2025 to 174.6 million, roughly in line with the adult category's 7 percent growth to 520.4 million, and general fiction, humor, and children's and YA were called out as the fastest-growing genres in the APA's separate revenue data. A production category outside the general fiction and self-help titles that dominate most narrator advice is worth a second look for exactly this reason.

The Library Squeeze Behind the Boom

None of this growth is free for the libraries funding it. E-content licensing can cost a library up to three times the price of a physical copy of the same title, with publisher terms like HarperCollins' 26-checkout-per-license cap and Hachette's two-year license windows adding real, recurring cost on top of the initial price. Wake County, North Carolina's public library system saw its digital circulation rise from about 1.1 million checkouts in fiscal year 2019 to more than 3.5 million in fiscal year 2026, a 200 percent increase, a growth rate its own librarians describe as outpacing what their budgets can comfortably absorb.

"It's really a challenge when a book is so popular. Our clients end up waiting a fair amount of time to get access."

Macintyre's point matters for the production side of this market too: a library holds queue that stretches for months on a popular title is direct evidence of real, unmet listener demand, which is a genuinely good sign for the format's future. It is not, on its own, evidence that narrator pay or narrator demand is rising at the same pace as listener appetite, since a library paying more for licenses is a cost absorbed well upstream of any individual narration contract.

The AI Narration Reality Check

Given how much anxiety AI narration understandably generates among working narrators, the actual revenue data is worth stating plainly: AI-narrated audiobooks accounted for just 0.03 percent of audiobook sales revenue in 2025, according to the same Edison Research survey conducted for the APA. Consumer willingness to even try an AI-narrated title fell, rather than rose, from roughly 70 percent in 2025 to 61 percent in 2026, and only about 16 percent of listeners report having actually listened to an AI-voiced title at all. The headline growth in AI-narrated title counts, real as it is, has not yet translated into meaningful revenue share or rising listener enthusiasm, at least as of the most recent survey data available.

What This Means for a Working Narrator

The honest synthesis of this data is neither the panic narrative nor the boom narrative on its own. Listener demand for audiobooks is real and still growing by every credible measure, library checkouts, industry revenue, and survey-reported listenership alike. Supply is growing even faster, which means a narrator's individual prospects depend far more on genre fit, production quality, and relationship-building than on riding a rising tide that lifts every narrator equally. How long it actually takes to edit an audiobook and choosing between royalty share and per finished hour both matter more, not less, in a market where more titles are chasing the same production budgets and the same listening hours.

Audiobook narrator demand more broadly is worth revisiting alongside this data rather than in isolation, since the two pieces together give a more complete picture than either does on its own: real, growing listener demand at the top of the funnel, and a genuinely more competitive, title-saturated market for narrators actually producing the supply underneath it.

Frequently Asked Questions

Is the audiobook narration market actually saturated?

The data shows title supply growing considerably faster than revenue, which is a real signal worth taking seriously, but "saturated" is a stronger word than the numbers alone support. Listener demand is still growing every year by every measure available; the more accurate read is a market getting more competitive per title, not one that has stopped growing.

Does genre choice actually matter for booking narration work?

The data suggests it might matter more than general advice implies. General fiction, humor, and children's and YA were the fastest-growing categories in the most recent APA revenue data, and children's and YA checkouts kept pace with the far larger adult category in library lending. A narrator weighing which genres to build samples in has real, sourced data to weigh alongside personal fit.

Should I be worried about AI narration taking over the market?

The most recent revenue and consumer-willingness data does not support near-term alarm: AI narration remains a vanishingly small share of actual revenue, and listener interest in trying it has fallen rather than grown in the latest survey. That could change, and it is worth continuing to watch, but as of the most recent data it has not happened yet.
