A federal judge has officially signed off on Anthropic’s $1.5 billion class action settlement with authors who accused the AI firm of training its models on copyrighted books. In an order issued Monday, Judge Araceli Martínez-Olguín stated that the settlement provides “meaningful relief,” granting authors approximately $3,000 for each book allegedly pirated by the company.
A Historic Copyright Recovery
The $1.5 billion figure represents the “largest known copyright recovery in history,” according to the legal team representing the plaintiffs. The legal battle began in 2024 when authors Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson filed suit. While the now-retired Judge William Alsup initially granted Anthropic a partial victory, he later allowed a class action to proceed, comparing the company's actions to the “Napster-style downloading of millions of works.”
Anthropic reached the settlement agreement in September 2025, following preliminary approval from the court. The resolution marks a significant milestone in the ongoing tension between generative AI development and intellectual property rights.
Participation and Ongoing Litigation
Anthropic’s general counsel, Aparna Sridhar, confirmed to Reuters that more than 91% of eligible authors and publishers have claimed their portion of the settlement. Despite this high participation rate, the company’s legal troubles are not entirely over. Anthropic continues to face copyright lawsuits from Chicken Soup for the Soul and other authors who contend that the $3,000 per book payout is insufficient compensation for the use of their intellectual property.
