Anthropic Proposes $1.5 Billion Author Settlement Over Pirated Book Training Data

Preliminary approval now rests with Judge William Alsup after the parties detailed a $1.5 billion fund with data‑purge obligations.

Overview

  • Filings ask the San Francisco court for preliminary approval, with a hearing scheduled for Monday before Judge William Alsup.
  • The proposed class fund equals about $3,000 per work for roughly 500,000 books, with more to be paid if additional eligible works are identified.
  • Anthropic would destroy downloaded datasets acquired from shadow libraries including Library Genesis, Pirate Library Mirror and Books3.
  • Payments are staged in four tranches: $300 million after preliminary approval, $300 million after final approval, then $450 million within 12 months of preliminary approval and $450 million a year later.
  • The release covers past conduct through Aug. 25, 2025 and does not grant a license for future training, authors retain opt‑out rights, and broader fair‑use and output‑infringement issues remain unresolved.
