Penguin Random House uses machine learning tools, developed by its internal data science teams, to forecast book sales and manage inventory levels. The company has confirmed this practice has been in place for over a decade.

PRH's data science teams have built machine learning models that predict demand — for example, determining the starting print run for a new title or setting the selling price for an e-book. The company has also posted job listings for Senior Machine Learning Scientists focused specifically on e-book pricing and forecasting, describing these as existing production systems. These are internal tools used by operations and supply chain staff, not exposed to readers.
