Judge Approves $1.5 Billion Anthropic AI Copyright Settlement

U.S. District Judge Araceli Martínez-Olguín approved a $1.5 billion settlement on Monday, marking what is believed to be the largest payout ever for a U.S. copyright suit. This settlement resolves a 2024 copyright infringement lawsuit filed by a group of authors, including Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson. The authors accused Anthropic of "large-scale theft" by using pirated copies of books to train its AI chatbot, Claude. The lawsuit claimed that Anthropic illegally accessed copyrighted books from online libraries.

While a previous ruling by retired Judge William Alsup in June 2025 stated that AI could be trained on copyrighted books, he also determined that Anthropic had accessed these books illegally. The case was scheduled to go to trial in December, with potential damages estimated in the hundreds of billions of dollars for Anthropic. However, the company opted to settle for $1.5 billion in September.

Under the terms of the approved settlement, each member of the class action lawsuit could receive between $200 and $150,000 per work. The estimated per-work payment is approximately $3,000. Judge Martínez-Olguín has now taken over the case from Judge Alsup and has given her final approval to the settlement.

Anthropic has faced scrutiny over its data sourcing practices, similar to other major AI companies. Meta Platforms, the parent company of Facebook, and OpenAI, the maker of ChatGPT, have also been targets of copyright lawsuits from authors. The outcome of this settlement could set a precedent for future cases involving AI training data and intellectual property rights.

In addition to approving the Anthropic settlement, Judge Martínez-Olguín also granted a temporary halt to the Paramount-Warner Bros. merger on the same day. This action was taken following an argument by a 12-state coalition, led by California, that the merger would violate antitrust law. The judge's decisions highlight significant legal developments in both the technology and media sectors.
