A federal judge has granted final approval to Anthropic's $1.5 billion settlement in a class action copyright lawsuit brought by authors and publishers, clearing the way for the AI company to begin compensating rights holders whose works were used without permission.
Judge Araceli Martinez-Olguin of the U.S. District Court for the Northern District of California signed off on the agreement on Monday, according to Reuters. The settlement is widely regarded as the largest in the history of U.S. copyright law.
How the Settlement Breaks Down
The payout will distribute approximately $3,000 per work across an estimated 500,000 copyrighted books, with the funds shared among the authors and publishers who hold the rights to those works. The deal resolves a lawsuit that originated after Judge William Alsup, who has since retired, ruled that Anthropic had illegally downloaded and stored millions of copyrighted books to build its AI training library.
Alsup had issued a preliminary approval of the settlement last year. His retirement meant the final approval fell to Judge Martinez-Olguin, who formally closed the case this week.
A Split Legal Verdict: Fair Use vs. Piracy
Despite the historic dollar amount, many authors and creators do not consider the outcome a victory. The reason lies in how the underlying legal questions were resolved.
On the central issue of whether training an AI model on copyrighted text constitutes fair use, Alsup sided with Anthropic. That decision was widely viewed as a pivotal moment for the AI industry, suggesting that companies can legally use copyrighted material to train their models under the doctrine of fair use.
However, the ruling drew a sharp distinction between the act of training and the method of obtaining the training data. Anthropic built its library from two sources: physical books it purchased and legally scanned, and digital books it downloaded from pirate websites such as Library Genesis and Pirate Library Mirror. Alsup found the latter method to be plainly illegal and indicated that the piracy question could proceed to trial.
