US District Judge Araceli Martínez-Olguín granted final approval to Anthropic's $1.5 billion copyright settlement on July 20, 2026, concluding the class-action lawsuit Bartz v. Anthropic PBC. The settlement covers approximately 482,000 copyrighted works, with about 91% of the affected authors and publishers claiming their share. Bloomsbury Publishing, which had 14,087 titles listed in the settlement, said it expects to receive approximately $19 million (£14 million) from the payout, pending deductions.

The litigation originated on August 19, 2024, when bestselling novelist Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson filed a copyright infringement complaint (docket 4:24-cv-05417) in the US District Court for the Northern District of California. According to the Authors Guild, Anthropic downloaded approximately 7 million copies of books to train its AI models. A federal judge granted preliminary approval to the settlement on September 25, 2025. Judge Martínez-Olguín, who oversaw the final approval, stated the settlement provided 'meaningful relief' to affected authors and publishers. The case docket records the last known filing on July 10, 2026.

Justin Nelson, the authors' lead lawyer, described the settlement as 'the largest known copyright recovery in history.' The attorney fee award in the settlement exceeds $100 million, though a federal judge previously reduced the plaintiffs' legal fee award, rejecting what was characterized as a 'windfall' for the lawyers. The final settlement structure follows a May 14, 2026 court hearing where the judge considered the proposed agreement, which ultimately saw nearly 120,000 authors and other copyright holders seek a share of the $1.5 billion fund.

For Bloomsbury, the financial impact involves a proposed compensation baseline of about $3,000 per title. After a deduction of about 10% for attorney fees and expenses, the publisher said it can expect to receive the settlement cash in installments, potentially starting in the second half of this fiscal year. Bloomsbury confirmed the US District Court's formal approval via a regulatory announcement through the London Stock Exchange's Regulatory News Service under ticker BMY. Anthropic's deputy general counsel, Aparna Sridhar, issued a written statement expressing satisfaction that more than 91% of authors and publishers covered by the settlement have claimed their share.

The Anthropic settlement is the first major resolution out of dozens of AI copyright lawsuits filed in the US on behalf of authors and news outlets. The docket for Bartz v. Anthropic PBC also records filings from industry groups including the Textbook and Academic Authors Association, which filed a joint motion regarding settlement administration updates, and Anna Ganley of the Society of Authors, who filed a declaration in support of the preliminary approval motion.

Looking at the broader context, this settlement establishes a concrete financial baseline for unauthorized use of copyrighted works in AI training data. The per-title compensation figure provides a metric that will likely inform future litigation and legislative debates over training data licensing. Bloomsbury's parallel approach to AI licensing is also notable. In 2025, the publisher announced an AI licensing deal allowing it to sell academic works to train generative AI programs, where authors could opt in and receive royalties. This dual track, pursuing compensation for past unauthorized use while establishing future licensing frameworks, indicates how publishers are navigating the intersection of intellectual property and machine learning.
