Bloomsbury to collect millions from Anthropic's $1.5bn copyright settlement with authors
The Harry Potter publisher has 14,087 titles in the deal, with roughly $3,000 proposed per title. It is one of the largest payouts so far in the long legal fight over AI training data.

Key points
- Anthropic, the AI company behind the Claude chatbot, agreed to a $1.5 billion settlement with thousands of authors over the use of their books to train its AI systems.
- Bloomsbury Publishing, the Harry Potter publisher, holds 14,087 titles inside the settlement as of the announcement date.
- Each title carries a proposed compensation of approximately $3,000.
- Bloomsbury's catalogue includes authors Sarah J Maas, Susanna Clarke and J.K. Rowling.
Bloomsbury Publishing is set to receive a multimillion-pound payout after being named a beneficiary in a $1.5 billion copyright settlement between Anthropic, the American AI company behind the Claude chatbot, and thousands of authors whose books were used to train that system without their permission.
The Guardian first reported the details of Bloomsbury's share in the deal. The publisher says it has 14,087 titles listed within the settlement. Proposed compensation sits at roughly $3,000 per title.
Do the rough arithmetic and Bloomsbury's slice of the pot could reach around $42 million, though that figure depends on how the final settlement is structured and approved.
The case centres on a practice that has become one of the biggest flashpoints in AI law. Companies like Anthropic trained their large language models, the technology that powers chatbots like Claude, on vast datasets that included published books, often without asking authors or paying them. Authors argued this broke copyright law. Anthropic disputed that, but settlement talks produced this agreement.
For working writers, this settlement matters. It signals that AI companies may not treat published books as free raw material indefinitely. Whether $3,000 per title feels fair is another question: a novelist who spent three years writing one book gets the same as a pamphlet. Critics of the deal are likely to raise exactly that point during court approval hearings.
Bloomsbury's authors range from J.K. Rowling, whose Harry Potter series is among the best-selling fiction of all time, to Sarah J Maas, whose fantasy novels have sold tens of millions of copies, to Susanna Clarke, author of the Booker-longlisted Piranesi. None of them have commented publicly on this specific settlement figure yet.
What does this mean for readers and writers?
For readers, the settlement will not change how Claude works or how much a subscription costs. For authors, it sets a precedent: courts and companies are now accepting, at least in part, that training AI on books without consent has a price.
The settlement still needs court approval before any money moves. Writers whose titles are listed inside the agreement will eventually be contacted about their share. Authors not currently covered would need to pursue separate legal action.
This is one case among several working through courts on both sides of the Atlantic. How judges and regulators respond to each will, together, shape whether AI companies continue training on copyrighted material and, if so, what they pay for the privilege.
