a16z: AI-Generated Books Capture 40% of Self-Published Sales, Winning by Volume
a16z · x · 2026-08-08
A recent chart analysis from a16z highlights how generative AI is disrupting publishing. A joint academic study indicates that AI-generated books are flooding the self-published market, now capturing around 40% of observed sales.
Since 2023, the total catalog of self-published new books has surged nearly 40x, while actual revenues have only increased about 9x. This suggests AI authorship adopts a high-volume strategy: although the hit rate per book is lower, drastically low production costs have scaled the catalog massively, diluting the overall market. While non-AI books still earn more per title, the revenue gap is closing rapidly.
