Published market figures do not point to a decline. Writer Cosmos reports the global books market at approximately $135.49 billion in 2026, growing at a 3.11% CAGR, and says the global self-publishing market is growing at a 16.7% CAGR. Formats keep shifting across print, ebooks, and audio, but people are still buying books.
Neither is better for everyone. Writer Cosmos, citing ALLi's 2025 survey, reports that indie authors earn a median of $13,500 a year, compared with a $6,000 to $8,000 median for traditionally published authors. Self-publishing offers more control and speed; traditional publishing offers an established route into bookstores but is harder to enter.
One self-publishing guide says authors will make anywhere from $1 to $3 per book, using a $14.99 list price as its example. Actual earnings depend on format, printing cost, platform, and royalty rate. For most CEOs, the larger return comes from the clients, speaking, and media opportunities a book creates rather than royalties.
Many self-published authors price ebooks between $2.99 and $9.99, because one self-publishing guide notes that range earns the highest royalty rate. Writer Cosmos describes authors keeping up to 70% royalties on ebooks. For a CEO, price often matters less than putting the book in front of the right readers, since the book's main job is building authority.
Widely used self-publishing platforms include Amazon Kindle Direct Publishing (KDP) and Lulu, which offers free ebook creation and self-publishing. The right choice depends on where your readers buy books. One self-publishing guide reports that more than 80 percent of all US ebook sales happen through a single online retailer, Amazon, which is why many authors start there.
A book that builds authority pays off in opportunities, not just copies.
