Judge Rules Anthropic Trained Claude on Pirated Books
In a May 2026 lawsuit, a federal judge ruled Anthropic illegally pirated and scraped books by over 10 Stanford professors to train Claude, while training on legally acquired books counts as fair use. The $1.5 billion Bartz settlement went to authors and publishers of nearly 500,000 works; some authors call it insufficient and filed a separate suit.
