Judge preliminarily approves Anthropic's $1.5B authors settlement
Judge William Alsup of the Northern District of California granted preliminary approval on Thursday to Anthropic's $1.5 billion class settlement with authors Andrea Bartz, Charles Graeber and Kirk Wallace Johnson — roughly $3,000 per work plus interest across an estimated 500,000 books, with the allegedly pirated datasets to be destroyed. It is the largest publicly reported copyright recovery to date and settles legacy claims only; it does not cover works created or ingested later. Final approval follows the notice and claims process.
The settlement traces directly to Alsup's June ruling, which split the question: training on lawfully acquired books was fair use, but Anthropic's acquisition of millions of titles through Library Genesis and the Pirate Library Mirror was not. The damages land on the acquisition method, not the training itself.

WHY IT MATTERS
Provenance is now a priced risk. Keep a per-source ledger for every corpus that touches training, fine-tuning or a retrieval index, and get indemnities in writing from dataset vendors and user-upload terms, because the exposure here was created by how the data was obtained rather than what it was used for. The per-work unit price also gives you a defensible number to put against unlicensed scraping in any build-versus-buy conversation.
