Anthropic wins court approval for record AI copyright settlement

The ruling concludes the first major AI copyright class action to end in a settlement in the US, while reinforcing the legal distinction between AI model training under fair use and the unlawful acquisition of copyrighted works.

Anthropic has secured final court approval for its $1.5 billion settlement with a group of authors who accused the artificial intelligence company of using copyrighted books to train its Claude AI models without permission. The approval marks the conclusion of the first major AI copyright class action in the United States to end through a settlement and is being described as the largest copyright recovery of its kind.

The settlement was approved by US District Judge Araceli Martinez-Olguin in San Francisco after receiving preliminary approval last year. The case has been closely watched by the technology and publishing industries as legal disputes over the use of copyrighted content for training generative AI systems continue to grow.

Settlement follows landmark copyright ruling

The agreement comes after a landmark court ruling that found the use of copyrighted books for training AI models qualifies as fair use under US copyright law. Anthropic said the legal clarification provided the foundation for resolving the dispute.

Commenting on the development, Aparna Sridhar, Deputy General Counsel, Anthropic, said: "We reached this settlement in 2025, after the court’s landmark ruling that training AI on books is fair use under copyright law, which remains the law today."

She added: "We are pleased that more than 91% of authors and publishers covered by the settlement have claimed their share of the payment, and we’re looking forward to bringing this matter to a close."

The authors' legal team also described the outcome as a significant milestone.

Justin Nelson, lead counsel for the plaintiffs, said:"It is the largest known copyright recovery in history. We look forward to making distributions to the class as promptly as possible."

Court separates AI training from piracy claims

The lawsuit, filed in 2024, alleged that Anthropic relied on pirated copies of books to develop its Claude AI chatbot and maintained a digital repository containing more than seven million copyrighted titles, many of which were allegedly never used for model training.

In its earlier ruling, the court distinguished between the use of copyrighted material for AI training and the manner in which such content was acquired. While it concluded that AI training could fall under the doctrine of fair use, it also held that Anthropic could still face liability over allegations that it downloaded and stored millions of pirated books in what was described as a central digital library.

The decision is expected to serve as an important reference point for future copyright disputes involving generative AI developers, publishers and content creators, as courts continue to define the legal framework governing AI training practices.
