News Anthropic 1.5B Settlement 2026
'April 6, 2026 — Anthropic has agreed to a $1.5 billion settlement in Bartz et al. v. Anthropic PBC, case No. 3:24-cv-05417-AMO (N.D. Cal.), resolving claims by authors whose books were downloaded from pirated sites LibGen and PiLiMi for AI training.[1][2][3]
Background
The lead plaintiffs are authors Andrea Bartz, Kirk Wallace Johnson, and Charles Graeber, who alleged that Anthropic's Claude AI assistant was trained on pirated copies of books from "shadow library" websites LibGen and PiLiMi.[1][2] The settlement followed partial summary judgment favoring plaintiffs on pirated books, finding that such use was not fair use.[1]
Details
The $1.5 billion fund covers approximately 500,000 works at roughly $3,000 per work, with additional payments if more works are added.[1][2] Payments are structured in installments: $300M by October 2, 2025; $300M post-final approval; $450M by September 25, 2026; and $450M by September 25, 2027.[1][3] The settlement covers only past ingestion claims up to August 25, 2025; it does not release claims for future training, AI outputs, or commercial model use from these datasets, and includes dataset destruction provisions.[1][4]

Objections
Class objections include:[7][8]
- Publisher favoritism: Objector Professor Bishop (Dkt. 630) argues the settlement systematically favors publishers over authors — publishers could claim roughly 50% or more of the total settlement through royalty presumptions, despite the suit being author-led[7]
- Foreign work exclusion: Bishop also challenges the exclusion of over 2 million foreign and non-U.S.-registered works, arguing this improperly narrows the class[7]
- Late notice: Objector Esquivel received notice of the settlement on approximately March 3, 2026 — nearly a month after the February 9 opt-out deadline had expired[7]
- Group registration undercounting (Dkt. 641): Multiple books registered under a single copyright registration are treated as one "claimable work," dramatically undercompensating prolific authors (e.g., 40+ books counted as a single work)[7]
- Dangerous precedent (Dkt. 640): The settlement allows AI companies to settle mass piracy at a discounted rate — cheaper than licensing — setting a harmful precedent for future AI copyright disputes[7]
- Class counsel conflicts: References Judge Alsup's December 2025 concerns about undisclosed fee-sharing arrangements between class counsel[8]
- Inadequate compensation: Base awards of approximately $3,000 per work before deductions for attorneys' fees and costs, with a tiered system paying more for "important" (nonfiction) books over fiction[8]
Objectors may participate in the May 14, 2026 fairness hearing via Zoom.[9]
Broader context
Anthropic was the first major AI company to settle one of the foundational AI training copyright cases. Class counsel seeks approximately $319M in fees and costs (21.26% of the fund), with named plaintiffs requesting $50K each.[1][10]
