Anthropic agrees to pay $1.5B and destroy the pirated library
In a filing on Friday, Anthropic and the plaintiffs in Bartz v. Anthropic asked Judge William Alsup to approve a $1.5 billion settlement: roughly $3,000 per work across an estimated 500,000 books, paid in four instalments starting at $300 million, plus destruction of the original book files the company downloaded. Plaintiffs' counsel called it the largest publicly reported copyright recovery in history, and a preliminary-approval hearing was set for September 8.
The figure lands exactly where June's ruling left the case. Alsup found that training on books Anthropic had lawfully acquired was transformative fair use, but held that assembling a library of more than 7 million pirated books from Library Genesis and Pirate Library Mirror was not — and that is the liability the money closes. Anthropic still faces a separate suit from major record labels over song lyrics.

WHY IT MATTERS
This is the first hard price tag on training-data provenance, and it is per-work and retroactive: roughly $3,000 a document. If any part of your corpus, fine-tune set or RAG index came from an unvetted scrape, that is now the unit cost of having been wrong — licensing or buying the corpus is the cheaper line item, and the destruction clause means keeping a copy just in case stops being a defense.
