U.S. District Judge Araceli Martinez-Olguin signed off on the deal Monday, making it the largest known copyright settlement in U.S. history.

The lawsuit was filed in 2024 by authors who claimed Anthropic used pirated versions of their books without permission to train its Claude chatbot.

The case was part of a wider wave of copyright lawsuits brought by authors, publishers, and news outlets against AI companies over the use of copyrighted material to train large language models.

What the Court Found

An earlier ruling by then-Judge William Alsup found that Anthropic’s use of books to train Claude was fair use under U.S. copyright law.

However, the court also found that Anthropic had stored more than 7 million pirated books in a digital library that was not necessarily used for training purposes. That was ruled a copyright violation.

A trial to determine damages from the pirated library had been scheduled for December, with potential liability running into the hundreds of billions of dollars. The parties settled before it went ahead.

Anthropic Deputy General Counsel Aparna Sridhar said the settlement was reached in 2025, following the fair use ruling, and that more than 91% of eligible authors and publishers have already claimed their payments.

Objections Overruled

Some authors pushed back on the deal, arguing the $1.5 billion figure was too low, that attorneys were being paid too much, and that some copyright holders were wrongly excluded.

Judge Martinez-Olguin rejected all those objections. She said concerns about the settlement’s size were not based on a realistic view of the risks of going to trial.

The judge awarded plaintiffs’ attorneys more than $101 million in legal fees, less than the $187.5 million they had requested.

Lead attorney Justin Nelson called the outcome a “historic settlement” and described it as the largest known copyright recovery in history.

Distributions to class members are expected to begin as soon as possible, according to Nelson’s statement.

Not all authors accepted the deal. A number opted out of the class action and have filed their own separate lawsuits against Anthropic, which remain ongoing.

The case is one of dozens involving AI companies and copyright holders still working through U.S. courts.
