Read MoreJudge Approves Anthropic's $1.5 Billion Copyright Settlement: Precedents and Industry Impacts of AI Training Data Piracy
On July 20, 2026, U.S. federal judge Martínez-Olguín in California officially approved the $1.5 billion settlement reached by Anthropic with a group of authors in the case *Bartz v. Anthropic* — one of the largest copyright class-action settlements in U.S. history. Previously, Judge Alsup had ruled that training Claude on copyrighted books constituted fair use, but mass downloading of pirated books from LibGen and PiLiMi to build a "central library" constituted copyright infringement. The settlement provides approximately $3,000 in compensation per work, requires the destruction of pirated copies, and 91% of affected authors have filed claims. This article sorts out the context of the case, the dividing line between fair use and piracy, and three implications for the compliance of AI training data.
