a16z's Charts of the Week shares new data on AI's impact on publishing. Research from institutions like Stony Brook and Columbia indicates that AI-generated books are proliferating in the self-publishing sector.
Data reveals that books with detectable AI text now capture around 40% of observed sales. Since 2023, the total catalog of self-published new books has surged nearly 40x, while actual revenues have only grown about 9x. This suggests AI-generated content adopts a high-volume, low-cost strategy; despite a lower hit rate, the extremely low barriers to entry and massive output have allowed AI books to secure a significant market share and dilute the overall market.
