Anthropic's Record $1.5 Billion AI Copyright Settlement Approved
A federal judge in San Francisco has officially signed off on artificial intelligence company Anthropic's landmark $1.5 billion settlement. The class action lawsuit was brought by a group of authors who accused the company of misusing their books to train its AI chatbot, Claude.
U.S. District Judge Araceli Martinez-Olguin granted final approval of the agreement, cementing it as the largest known settlement of a U.S. copyright case. In doing so, the judge firmly rejected arguments from some objectors who claimed the payout was too small.
A Historic Moment for AI and Copyright Law
This lawsuit, originally filed in 2024, is one of dozens brought by copyright owners—including authors and news outlets—against major tech companies over the training of their large language models (LLMs). Crucially, this is the first major U.S. case of its kind to successfully reach a settlement.
The writers argued that Anthropic, which is backed by tech giants Amazon and Alphabet, used pirated versions of their books without permission to teach Claude how to respond to human prompts.
Last June, now-retired Judge William Alsup ruled that Anthropic actually made "fair use" of the authors' work to train Claude. However, Alsup found that the company violated the authors' rights by saving more than 7 million pirated books to a centralized library, which was not necessarily used for AI training. A trial to determine the damages for this alleged piracy was scheduled for last December, with potential liabilities running into the hundreds of billions of dollars.
"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," stated Anthropic deputy general counsel Aparna Sridhar. "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."
Overruling the Objections
The settlement did face some resistance. Certain authors argued it was not large enough, overcompensated the plaintiffs' attorneys, or wrongly excluded some copyright owners.
Judge Martinez-Olguin overruled those objections on Monday, stating that complaints about the settlement's size were "not grounded in a realistic assessment of the overall risks and rewards of a trial." She also awarded the plaintiffs' attorneys over $101 million of the $187.5 million they had requested in fees.
"It is the largest known copyright recovery in history. We look forward to making distributions to the Class as promptly as possible," said Justin Nelson, the lead attorney for the authors.
While the majority of the class has accepted the payout, some authors and publishers chose to opt out of the settlement entirely and are continuing to pursue separate, ongoing lawsuits against Anthropic.
