Ranking the Audiobook Genres by Sales in 2025

Introduction

We have once again analyzed the available sales data from Audible to answer that perennial question: Which audiobook genres are the most popular with listeners? Below you will find the results for the top and second-level tiers, as well as the 2024 results for comparison.

Finding the data

Accessing data to compare audiobook genres poses challenges. Nevertheless, Amazon, the parent company of Audible, offers a comprehensive, publicly available source. Amazon publishes rankings of top titles by genre, including a dedicated section for audiobooks. These are categorized into three tiers: top-level genres, second-tier sub-genres or categories, and a third level of niche categories.

The categorization by Amazon, especially at the second tier, sometimes seems arbitrary, with notable overlaps. For instance, Science Fiction and Fantasy share a top category, while Horror is relegated to a second-tier category under Literature. Literary Fiction is tucked away as a third-tier category under Genre Fiction. Romance and Erotica are distinctly separated, a decision likely to spark debate.

Genre classification challenges

Book genres are inherently complex to quantify and segment. Many books blend multiple genres, making it difficult to place them definitively. For example, where does a shapeshifter love story belong: Fantasy or Romance? The bestseller Atomic Habits is another case, listed under Business & Careers, Health and Wellness, and Relationships, Parenting, and Personal Development. Notably, several books appear in multiple categories, sometimes ranking at the top in at least six different ones, such as the Harry Potter series. This year, The Empyrean titles by Rebecca Yarros feature at the top of nearly a dozen fiction categories. This makes isolating these outliers increasingly important for our analysis.

Additionally, many genres have sub-categories that overlap with other categories. There is a certain amount of repetition and redundancy within Amazon's genre structure. We have calculated our data using the genre structure as presented.

Isolating top ten outliers

In many categories, the top ten includes highly popular titles that are often not reflective of the overall sales trend for that genre. Our ranking measures reduce the impact of such titles to near negligible levels and accurately reflect the popularity of the genre overall.

Data analysis and insights

Despite these categorization challenges, the available data offers substantial insights. By examining the overall rank of titles across genres, we can identify which genres house the most top-selling books. We analyzed the top one hundred sellers in each first- and second-tier category, delving deep into the rankings. With an estimated 800,000 audiobooks on Audible, these trends likely reflect broader market dynamics.

Comparative popularity ranking

Our analysis ranks genres relative to each other based on the combined overall rank of the top one hundred titles in each category. The top-selling genre receives a benchmark rank of 100. Subsequent categories are rated on a scale from 100 to 0, with higher numbers indicating closer proximity to the top genre's sales rank. Example: A genre with a ranking of 20 is four times more popular (based on sales) than a genre with a rank of 5.

The “die-off” figure

We introduced the “die-off” number to measure the decline in sales rank from the tenth to the one-hundredth title within a genre. This metric helps assess whether a genre's sales are dominated by its top titles or if lower-ranked titles also enjoy significant sales, making them viable investments for producers and publishers. Example: A genre with a die-off of 10 means that sales drop twice as fast for books outside the top ten sellers as a die-off of 5. A higher number indicates that a greater proportion of total sales within a genre is concentrated in the top-selling titles, rather than being distributed across less popular ones.

Conclusions

Our findings challenge the conventional wisdom that Romance and Thrillers dominate sales, with Fantasy performing exceptionally well. As these ratings are relative, it is possible to notice a definite shift away from non-fiction towards fantasy, and an increase in the demand for fantasy titles of all types.

We invite your thoughts on these findings and look forward to updating our analysis in January 2026.

Here, then, are the results!
