Anthropic Secures Court Approval for $1.5 Billion Authors’ Copyright Lawsuit Settlement

In a historic class action case, a number of writers accused Anthropic of utilising their works to train its artificial intelligence model. However, now the authors ultimately succeeded in getting a $1.5 billion settlement from the company. San Francisco-based US District Judge Araceli Martinez-Olguin green-lit what may be the biggest copyright settlement in US history on July 17th.

Judge William Alsup, who has since retired, gave his initial approval to the deal in September of last year. Notably, writers and news organisations have sued some prominent AI chatbot developers, claiming that these companies trained their AI models on copyrighted material without authorisation. Nevertheless, a settlement has been reached in the first major US AI copyright lawsuit.

Response From Anthropic

The company obtained this deal in 2025, following the court's groundbreaking finding that training AI on books constituted fair use under copyright law, said Anthropic Deputy General Counsel Aparna Sridhar. The verdict is still in effect today. Additionally, she mentioned that the firm is glad to see that over 91% of the publishers and authors included in the settlement have already claimed their portion of the payment.

The AI firm is eager for this situation to be resolved. It was dubbed a "historic settlement" by Justin Nelson, the authors' lead attorney. According to Nelson, it is the biggest copyright recovery ever. "We look forward to making distributions to the class as promptly as possible," Nelson added. In 2024, a number of writers sued Anthropic, claiming that the company had trained its Claude AI chatbot using illegally obtained copies of their books.

Specifics of Anthropic’s Lawsuit

More than seven million books believed to be pirated were stored by Anthropic, according to the writers. The bulk of these books were kept in the company's central database, regardless of whether they were used to train the AI model or not. Judge William Alsup's historic decision last year established that fair use under US copyright law encompasses the use of copyrighted books to train AI models. Even yet, he did decide that Anthropic might face legal consequences for its "central library" that contained millions of illegally downloaded books.

Both parties decided to settle out of court before the December trial that was supposed to start determining damages—damages that could have reached hundreds of billions of dollars. A number of writers and publishers have voiced their opposition to the settlement proposal. The authors contended that the compensation was inadequate, that the plaintiffs' lawyers were enriched, and that some writers were unjustly left out of the deal.

But Judge Martinez-Olguin threw out those arguments, stating that the criticisms of the settlement's magnitude lacked a reasonable evaluation of the potential benefits and costs of going to trial. After the lawyers asked for $187.5 million in fees, the judge gave them more than $101 million.
