Judge Approves Anthropic’s $1.5 Billion AI Copyright Settlement With Authors

A federal judge in San Francisco has granted final approval to Anthropic’s landmark $1.5 billion copyright settlement, bringing a major chapter in the legal battle over AI training data and copyrighted books closer to an end. The agreement, approved on Monday by U.S. District Judge Araceli Martinez-Olguin, is considered the largest known settlement in a U.S. copyright lawsuit and marks the first major resolution among the growing wave of artificial intelligence copyright cases.

The class action was filed in 2024 by a group of authors who accused Anthropic of using pirated copies of their books without permission to train its AI chatbot, Claude. Anthropic, backed by Amazon and Alphabet, reached the settlement in 2025 following a court ruling that using books to train AI models constituted fair use under U.S. copyright law, while separately finding that the company infringed copyrights by storing more than seven million pirated books in a centralized digital library.

Anthropic welcomed the court’s decision, noting that more than 91% of eligible authors and publishers have already claimed their share of the settlement funds. The company said it looks forward to completing the distribution process and closing the case.

Lead attorney Justin Nelson described the agreement as a “historic settlement,” calling it the largest copyright recovery on record. Payments to eligible authors are expected to begin as soon as possible.

The case had been scheduled for trial last December to determine damages related to the alleged piracy, with potential financial exposure estimated in the hundreds of billions of dollars before the parties reached an agreement.

Some authors challenged the settlement, arguing that the payout was insufficient, the legal fees were excessive, or that certain copyright holders were unfairly excluded. However, Judge Martinez-Olguin rejected those objections, stating they failed to realistically account for the risks of continuing to trial. The court also approved more than $101 million in attorney fees, lower than the $187.5 million originally requested.

While the settlement resolves claims for participating authors, several writers and publishers opted out and continue to pursue separate copyright lawsuits against Anthropic over its AI training practices.
