Judge Approves Anthropic's $1.5 Billion Settlement Over Pirated Books Used to Train Claude

A United States federal judge has given final approval to a settlement in which Anthropic will pay roughly $1.5 billion to authors and publishers whose books were downloaded from pirate repositories and stored in the company's internal training corpus. District Judge Araceli Martínez-Olguín called the class-action deal "meaningful relief," according to TechCrunch and Marketplace. The agreement covers more than 482,000 works at about $3,000 each, and about 91% of eligible titles have already been claimed. A Russian-language summary of the decision circulated the same day on AI ML Big Data.

The structure of the payout matters as much as the total. Anthropic already paid $300 million into the fund after preliminary approval, with a further $300 million due shortly and two later tranches of $450 million on the first and second anniversaries. Plaintiffs' counsel described it as the largest known copyright recovery, a characterization the court did not dispute.

The legal logic is narrower than the number suggests. The court had earlier held that training models on books a company lawfully obtained is fair use. Anthropic's exposure came from a separate act: retaining more than seven million pirated copies in a central library that was not necessarily used for training at all. In other words, the liability attached to acquisition and storage, not to the act of learning from text.
