- About 482,000 works are covered under the settlement class list from pirate repositories Library Genesis and Pirate Mirror.

On July 20, 2026, U.S. District Judge Araceli Martinez-Olguin granted final approval to Anthropic's $1.5 billion settlement in a class-action lawsuit brought by authors accusing the AI company of illegally using their copyrighted works to train its chatbot Claude.
The lawsuit was initiated by authors Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson, who alleged that Anthropic had accessed hundreds of thousands of copyrighted books from pirate sites like Library Genesis and Pirate Mirror to develop its AI models without authorization.
The settlement covers approximately 482,000 works that met specific eligibility criteria, including having an ISBN or Amazon ASIN, registration with the U.S. Copyright Office within five years of publication, and registration predating Anthropic's downloads or falling within three months of publication. Eligible parties include individual authors, publishers, academic institutions, estates, and trusts.
Payments will be made in four installments: $300 million by October 2, 2025; another $300 million shortly after final approval; followed by $450 million each by September 25 in both 2026 and 2027. Authors' press releases estimate per-work payouts around $3,000, subject to claim submissions.
Beyond monetary compensation, Anthropic is obligated to destroy all files and derivative copies sourced from LibGen and Pirate Mirror within 30 days of the judgment. Importantly, the settlement does not license Anthropic to use these works for future AI training nor does it release any claims related to AI-generated output potentially infringing copyrights.
This settlement is considered the largest known in U.S. copyright litigation and is the first major resolution in lawsuits addressing AI training on copyrighted content. As legal battles continue, this case is likely to influence future agreements and guidelines between content creators and AI developers.
By the numbers:
- $1.5 billion — total settlement amount
- 482,000 works — covered under the settlement's final 'Works List'
- 4 installments — $300M due Oct 2, 2025; final payment by Sept 2027
What's next: Awaiting distribution of settlement funds to claimants and monitoring for potential appeals or further AI copyright litigation.
