Bloomsbury among publishers in line for payout from Anthropic’s $1.5bn copyright settlement

Bloomsbury, the London publisher known for the Harry Potter series, will collect a share of Anthropic's $1.5 billion copyright settlement, the largest in US history, after a federal judge approved the deal on Monday. The settlement stems from Bartz v. Anthropic, where the AI firm was found to have downloaded millions of pirated books to train its Claude models, with each eligible work drawing about $3,000 before legal fees, split equally between author and publisher.

Bloomsbury, the London publisher best known for the Harry Potter series, has confirmed it will collect a share of Anthropic’s $1.5bn settlement with authors, the largest copyright payout in US history. The company told the stock market this week that 14,087 of its titles sit on the list of works covered by the deal, which a federal judge signed off on https://thenextweb.com/news/anthropic-1-5-billion-copyright-settlement-approved on Monday. The money stems from Bartz v. Anthropic , the class action a group of writers brought after the AI firm was found to have downloaded millions of pirated books to train its Claude models. The case had already produced a rare fairness hearing https://thenextweb.com/news/anthropic-book-settlement-judge-fairness-hearing before Judge Araceli Martínez-Olguín granted final approval, inheriting the matter from Judge William Alsup, who has since retired. The three named plaintiffs, novelist Andrea Bartz and the non-fiction writers Charles Graeber and Kirk Wallace Johnson, first struck the agreement with Anthropic in September 2025. Alsup granted preliminary approval that month, and the case then passed to Martínez-Olguín for this week’s final sign-off. Under the terms, each eligible work draws compensation of about $3,000, before deductions for legal fees and court costs. Bloomsbury said the amount attached to each of its titles would be divided equally between author and publisher, leaving each side with around $1,500 per book. The company expects the cash to arrive in instalments beginning in the second half of its financial year, according to its regulatory filing. It did not put a total figure on its own share, and the sums remain subject to the court’s administration process. The settlement resolves one of the first real reckonings over how generative AI systems are built. Anthropic had bought and scanned physical books legally, but it also pulled roughly seven million copies from pirate repositories, Library Genesis in 2021 and the Pirate Library Mirror in 2022, a practice the court treated separately from the question of AI training itself. After duplicates and ineligible works were stripped out, about 500,000 distinct titles qualified for the class, each needing a US copyright registration to count. That distinction did most of the work. In June 2025, Alsup ruled that training models on copyrighted text could count as fair use, while acquiring pirated copies could not. Anthropic chose to settle rather than appeal, which leaves the fair-use finding as a single district-court opinion rather than binding precedent. Anthropic did not admit wrongdoing in agreeing to pay. The arithmetic still favoured a settlement, since statutory damages can reach $150,000 per infringed work, an exposure that, spread across a class this size, dwarfed the $1.5bn on the table and made a jury trial the larger gamble. Authors and publishers had until the end of March to lodge claims against the approved list of works. For publishers, the payout lands as they press near-identical claims elsewhere. Five houses are suing Meta over Llama https://thenextweb.com/news/publishers-meta-llama-copyright-class-action-2026 , and a separate group has taken Google to court over Gemini https://thenextweb.com/news/google-gemini-publishers-copyright-lawsuit , each arguing their catalogues were ingested without permission or payment. Those cases remain free to reach conclusions of their own, since the Anthropic ruling binds no one. Bloomsbury’s inclusion shows how far the settlement reaches beyond individual writers. The list of covered works runs to hundreds of thousands of titles, and the flat per-book formula means a large back catalogue converts into a meaningful cheque. The company has had a strong run regardless, buoyed by fantasy and romance sales and by academic titles picked up through acquisitions. The Anthropic money is a windfall rather than a rescue, and one it will share, title by title, with the authors whose work it published. When the payments clear, they will be among the first tangible transfers of money from an AI company to the writers and publishers whose books trained it. Whether the arrangement becomes a template or stays a one-off now rests with courtrooms that have yet to rule. Get the TNW newsletter Get the most important tech news in your inbox each week.
