The Antitrust Case Against Kindle Unlimited Exclusivity
{{KDP Select}} exclusivity resembles classic anticompetitive practices, conditioning the best royalty terms on not dealing with rival ebook stores. While Amazon faces active antitrust pressure ({{FTC v. Amazon}}, the EU's earlier ebook MFN settlement, and the {{Digital Markets Act}}), books are a low political priority, and exclusivity alone would not dissolve Amazon's distribution dominance because most readers already shop on Kindle.
Amazon's Kindle Unlimited exclusivity, enforced through KDP Select, maps onto patterns antitrust scholars scrutinize. Conditioning the best deal (KU page-read income plus promotional tools) on an author not distributing the digital book through competing stores functions like a loyalty rebate and an instance of exclusive dealing that can foreclose rivals such as Kobo, Apple Books, and Google Play from a supply of titles. The regulatory backdrop is real but blunt. The FTC v. Amazon lawsuit filed in September 2023 targets Amazon's broader online-marketplace conduct under Section 2 of the Sherman Act, not books specifically, though it cites the same dynamics: dominance, self-preferencing, and take-it-or-leave-it terms for dependent suppliers. The EU has been more aggressive on books: in 2017 the European Commission made binding Amazon's commitment to stop enforcing most-favoured-nation (price/terms parity) clauses in ebook contracts. The Digital Markets Act, which designates Amazon a \"gatekeeper,\" is the most plausible vehicle for a future ban on exclusivity clauses for the platform. Realistic interventions are narrower than \"breaking the superpower\": - **Banning exclusivity for self-published authors** is the most surgical fix: authors could enroll in KU and still sell elsewhere, forcing Amazon to compete on terms while the program survives. - **Mandating data portability and interoperability** (e.g., letting readers move their library to another reader, or native EPUB support) would weaken consumer-side lock-in. - **Structural separation or breaking up Amazon Publishing** is politically inconceivable and largely beside the point for KU exclusivity. The deeper obstacle is the network effect: Amazon takes a large majority of US ebook unit sales (commonly estimated around two-thirds, higher when KU borrows are counted), so even an author who could sell \"wide\" faces readers who already shop on Kindle. Antitrust can rewrite contract terms but cannot easily relocate where readers are. Books also rank below search, social media, and AI as a regulatory priority. The likelier erosion of KU's grip comes from slow market dynamics over a 10 to 20 year horizon: a credible unified subscription rival, gradual author defection as page-read rates soften, a cultural shift toward buying direct from authors (a \"Substack-for-fiction\" model that RoyalRoad partly embodies), and EU Digital Markets Act enforcement creating a wedge that may eventually cross the Atlantic.
