A new study analyzing 14,419 self-published genre-fiction books sold on Amazon between 2023 and 2026 reveals that generative AI-produced content, despite often being low-quality, is significantly impacting the book market. While these AI-generated books constitute a large portion of the catalog, they capture a smaller but growing share of sales. The influx of AI content has led to a market expansion where the number of books with sales grew nearly 20-fold, but revenue only increased about 9-fold, causing revenue per book to decline. This trend disproportionately affects books without AI text, particularly in genres with high AI diffusion and Kindle Unlimited availability. AI
