Judge Approves Anthropic $1.5B Copyright Settlement Legal · AI Industry Federal Judge Approves Anthropic's Record $1.5 Billion Copyright Settlement Over Pirated Books Used to Train Claude Published 21 July 2026 · Last updated 21 July 2026 A federal judge in San Francisco granted final approval on 20 July 2026 to Anthropic's $1.5 billion class action settlement, resolving claims that the AI company infringed copyrights by downloading and storing hundreds of thousands of pirated books from shadow libraries to train its Claude models. U.S. District Judge Araceli Martinez-Olguin, to whom the case was reassigned from Judge William Alsup in December 2025, approved the deal in Bartz et al. v. Anthropic PBC , Case No. 3:24-cv-05417 (N.D. Cal.). Plaintiffs' lead counsel Justin Nelson and multiple outlets describe it as the largest known copyright recovery in U.S. history. How the case reached this point Anthropic agreed to the $1.5 billion figure in late August 2025. The parties filed notice of a proposed class-wide settlement on 26 August 2025, and the dollar amount became public on 5 September 2025, the same day Judge Alsup granted preliminary approval. The agreement followed Alsup's June 2025 summary-judgment ruling, which created the exposure, and his certification of a class covering nearly half a million works. With a jury trial set for December 2025 and statutory damages that legal commentators estimated could reach the tens of billions of dollars, the parties settled before trial. Final approval came about eleven months later, on 20 July 2026. The settlement terms and class size The settlement fund totals at least $1.5 billion plus interest. It covers copyright owners of books with ISBNs or ASINs that Anthropic downloaded from Library Genesis (LibGen) in June 2021 and Pirate Library Mirror (PiLiMi) in July 2022, as defined by the certified class. The Works List contains approximately 482,460 works. As of 16 April 2026, the Authors Guild reported that 91.3 percent of those works (440,490) had been claimed by authors or publishers. The Association of American Publishers reported a final participation rate of 92.77 percent. Lead class counsel Justin Nelson stated at the final approval hearing that eligible rightsholders will receive approximately $3,100 per work on a gross basis, before deduction of attorney fees, administrative costs, and reserves. Earlier court filings had estimated roughly $3,000 per work. The settlement also requires Anthropic to destroy the files it obtained from the pirate repositories, reported by Courthouse News as due within 30 days of final judgment. One report describes the fund as payable in four installments dated 2 October 2025, 30 April 2026, 25 September 2026, and 25 September 2027. That schedule rests on a single secondary source and has not been confirmed against the settlement agreement, so it is carried here as reported rather than as a settled fact. Attorney fees and court costs Court reporting on the order states that Judge Martinez-Olguin awarded Class Counsel $101,561,111 in attorney's fees, roughly 7 percent of the fund. That figure reflects a 3.75 lodestar multiplier on a stated lodestar of about $27.08 million, reduced from the 6.92 multiplier and $187.5 million that Class Counsel had requested. Courthouse News also reported approximately $2,635,000 in reimbursed expenses, about $18.22 million in anticipated future administration costs, and a $15,000 service award to each of the three named plaintiffs. Objections overruled The court overruled objections from class members, including arguments that the per-work recovery was too small. According to court reporting, the judge wrote that the settlement was fair, reasonable, and adequate, and that success at trial was not assured. Legal context: fair use vs. piracy The settlement resolves only the claims arising from Anthropic's unauthorized acquisition and storage of the pirated books. It does not resolve claims related to the training of AI models or outputs generated by Claude. In a June 2025 ruling, then-Judge William Alsup held that training AI systems on copyrighted books can qualify as fair use, but that downloading and maintaining a central library of pirated books constituted infringement. Because Anthropic settled rather than appealing, that district court decision creates no binding precedent for other courts. No binding precedent on AI training fair use The fair use question for generative AI training remains open. On 10 July 2026, according to the Association of American Publishers, Hachette Book Group, Cengage Learning, Elsevier, and author Scott Turow filed a new putative class action against Google in the Southern District of New York, alleging piracy in the training of Gemini. Anthropic's position Anthropic Deputy General Counsel Aparna Sridhar stated that the company reached the settlement after the court's ruling that training AI on books is fair use, which she said remains the law today. Why this matters for the AI industry The approval closes one of the first major AI copyright class actions to reach final resolution. It shows the scale of potential liability for unauthorized use of copyrighted works in training data. Statutory damages for willful infringement can reach $150,000 per work, which across 482,460 works represented theoretical exposure that legal commentators estimated in the tens of billions of dollars.
