Anthropic settles $1.5B AI copyright lawsuit with authors

Anthropic settled a $1.5B lawsuit with authors over pirated books used to train its AI, covering 480,000 works. The deal requires data destruction but leaves AI fair use unresolved.

A federal judge in San Francisco has approved Anthropic's $1.5 billion settlement with a group of authors, marking the largest copyright payout in U.S. history. The 2024 lawsuit accused Anthropic of using pirated books to train its Claude AI chatbot and unlawfully storing over 7 million unauthorized works. The settlement covers more than 480,000 works, with claimants receiving about $3,000 per work—four times the statutory minimum. Over 91% of eligible authors and publishers have claimed their share, though some opted out to pursue separate lawsuits. Anthropic is also required to destroy all unauthorized data. While the court found that training AI on books could be considered fair use, storing pirated books was ruled a violation. The settlement reduces future litigation risks for Anthropic and is expected to boost investor confidence, but it does not resolve the broader question of fair use in AI training. The case sets a major precedent for copyright risks in the AI industry.
