Anthropic Agrees to $1.5 Billion Settlement Over Pirated Books Used to Train Claude

Anthropic has agreed to pay at least $1.5 billion to resolve a landmark class-action copyright lawsuit brought by authors and publishers, settling claims that the company illegally downloaded and stored roughly 500,000 pirated books to help build its Claude AI models. The agreement, reached in *Bartz v. Anthropic* before Judge William Alsup in the U.S. District Court for the Northern District of California, ranks among the largest copyright settlements on record and is being closely watched as a template for a wave of similar disputes across the AI industry.
