A federal judge in San Francisco approved a $1.5B settlement of a class-action copyright lawsuit against Anthropic in July 2026, capping a case that initially claimed the company trained Claude on pirated books. A June 2025 ruling established that using books for AI training constitutes fair use under copyright law, but Anthropic violated author rights by retaining 7 million pirated books in a central library beyond training use. With 91% of covered authors and publishers claiming settlement funds, the company has closed material legal exposure on training-data provenance. For financial institutions, this represents a quantified and settled balance-sheet cost for a major AI vendor, reducing tail risk around model training liability.
