"Nearly 120,000 authors and other copyright holders are seeking a share of a $1.5 billion class-action settlement with Anthropic over the company's unauthorized use of their books in artificial-intelligence training, according to a ​filing in California federal court.

Claims have been filed for 91% of the more than 480,000 ‌works covered by the settlement, according to a court filing  in the case on Thursday.

A judge will consider whether to grant final approval to the settlement – the largest ever in a U.S. copyright case – at a hearing next month.

Anthropic was the first and ​remains the only major AI company to settle a U.S. class-action by copyright holders alleging AI ​platforms used their work without permission to train their systems."

"Alsup signaled his discomfort with the proposal in a filing released the evening before the September 8 hearing, writing that he was “disappointed” that attorneys representing the author plaintiffs had left “important questions to be answered in the future, including respecting the Works List, Class List, Claim Form." He was especially concerned for works with multiple claimants with regards to the notification process, voicing worry over what would happen if one party wanted to opt-out of the settlement and the other did not...

In a statement, Authors Guild CEO Mary Rasenberger said the Guild was “confused” by the court’s suggestion that the Guild and AAP were working behind the scenes in ways that could pressure authors to accept the settlement “when that is precisely the opposite of our proposed role as informational advisors to the working group.”

The goal of the working group, which had been proposed by lawyers for the class, “is to ensure that authors’ interests are fully represented and to bring our expertise... to the discussions with complete transparency,” Rasenberger continued. “There are industry norms that we want to make sure are accounted for.”...

AAP CEO Maria Pallante offered an even more vigorous explanation of AAP’s role, as well as the role of the Guild, in the proceedings. “The Association of American Publishers and the Authors’ Guild are not-for-profits that have worked hard to support counsel in the case and to make sure that authors and publishers have the information they need,” Pallante said in a statement. “Unfortunately, the Court today demonstrated a lack of understanding of how the publishing industry works.”"

AI industry horrified to face largest copyright class action ever certified; Ars Technica, August 8, 2025

 ASHLEY BELANGER, Ars Technica ; AI industry horrified to face largest copyright class action ever certified

"AI industry groups are urging an appeals court to block what they say is the largest copyright class action ever certified. They've warned that a single lawsuit raised by three authors over Anthropic's AI training now threatens to "financially ruin" the entire AI industry if up to 7 million claimants end up joining the litigation and forcing a settlement.

Last week, Anthropic petitioned to appeal the class certification, urging the court to weigh questions that the district court judge, William Alsup, seemingly did not. Alsup allegedly failed to conduct a "rigorous analysis" of the potential class and instead based his judgment on his "50 years" of experience, Anthropic said.

If the appeals court denies the petition, Anthropic argued, the emerging company may be doomed. As Anthropic argued, it now "faces hundreds of billions of dollars in potential damages liability at trial in four months" based on a class certification rushed at "warp speed" that involves "up to seven million potential claimants, whose works span a century of publishing history," each possibly triggering a $150,000 fine.

Confronted with such extreme potential damages, Anthropic may lose its rights to raise valid defenses of its AI training, deciding it would be more prudent to settle, the company argued. And that could set an alarming precedent, considering all the other lawsuits generative AI (GenAI) companies face over training on copyrighted materials, Anthropic argued."

 "A federal judge in San Francisco ruled late on Monday that Anthropic's use of books without permission to train its artificial intelligence system was legal under U.S. copyright law.

Siding with tech companies on a pivotal question for the AI industry, U.S. District Judge William Alsup said Anthropic made "fair use" of books by writers Andrea Bartz, Charles Graeber and Kirk Wallace Johnson to train its Claude large language model.

Alsup also said, however, that Anthropic's copying and storage of more than 7 million pirated books in a "central library" infringed the authors' copyrights and was not fair use. The judge has ordered a trial in December to determine how much Anthropic owes for the infringement."
