AI-generated books now represent about 20 percent of Amazon's self-published catalog, according to data reported by The Decoder. Despite their significant presence, these AI-created titles only contribute to 12 percent of total sales within the self-publishing segment.
The rise of AI-generated content is having a notable effect on human authors, with revenue per book declining in seven out of eight examined genres. This suggests that while AI books are flooding the market, they are not translating proportionally into sales, putting financial pressure on traditional self-published writers.
For Japanese investors and market watchers, this trend highlights the growing influence of AI on creative industries globally, an area that could similarly disrupt local publishing and content-driven markets.
