U.S. District Judge Araceli Martinez-Olguin granted final approval for a $1.5 billion settlement between Anthropic and a class of authors on July 20, 2026. The lawsuit, originally filed in 2024, alleged that the AI company improperly used pirated versions of books to train its Claude chatbot. This agreement marks the largest copyright settlement in U.S. history and serves as the first major resolution among numerous pending legal actions by content owners against technology firms.

The litigation centered on whether training language models on copyrighted literature constitutes fair use. While Judge William Alsup ruled in June 2025 that training on the books was fair use, he found that Anthropic violated authors' rights by maintaining a central library of over 7 million pirated books that were not necessarily required for AI development. A trial to determine damages for this specific infringement was slated for December 2025 before the settlement was reached.

In her ruling, Judge Martinez-Olguin dismissed objections from certain authors who claimed the settlement amount was insufficient or the attorney fee distribution was unfair. The court awarded plaintiffs' attorneys more than $101 million of the requested $187.5 million in fees. According to Anthropic deputy general counsel Aparna Sridhar, more than 91% of eligible authors and publishers have already filed claims for their share of the funds. Despite this resolution, some copyright holders opted out of the settlement and continue to pursue separate, ongoing legal claims against the company.
