The largest copyright settlement in the U.S. history is officially crossing the finish line. On Monday, U.S. District Judge Araceli Martínez-Olguín granted final approval to Anthropic’s $1.5 billion class-action settlement, resolving a high-stakes legal battle brought forward by authors and book publishers against unauthorized use of works for AI training.
The lawsuit was originally filed in 2024 by bestselling novelist Andrea Bartz alongside other writers. It accused the Amazon– and Alphabet-backed AI company of using unauthorized copies of their works to train its Claude chatbot.
With final judicial approval secured, Anthropic can begin distributing funds to hundreds of thousands of rightsholders, bringing a historic chapter of AI litigation to a close.
Where the money goes and how the court ruled
Under the approved agreement, rightsholders receive roughly $3,000 per work, covering over 500,000 books. According to Anthropic’s legal team, more than 91% of affected authors and publishers have already submitted claims to receive their share (via Reuters).
The path to this deal follows a nuanced legal split established last year by now-retired U.S. District Judge William Alsup. In his landmark ruling, Alsup sided with Anthropic on the core issue of generative technology. He ruled that using copyrighted text to train AI models constitutes legal fair use.
However, Alsup also delivered a major blow to Anthropic in the way it acquired those books. Buying and scanning physical books was acceptable, but downloading millions of texts from pirate sites—like Library Genesis—crossed the line into copyright infringement.
Anthropic decided to settle rather than risk a trial over statutory piracy damages that could have been in the billions of dollars.
Navigating objections and late opt-outs
Approval did not come without friction. Some authors said the $3,000 payment was less than what they might have received in court. Plus, they did not like early calls for attorney fees.
Judge Martínez-Olguín addressed these concerns by slashing plaintiffs’ attorney fees from a requested $187 million down to approximately $101 million—roughly 7% of the total fund—reallocating those savings toward the class.
The judge also held a strict line on deadlines, blocking late attempts by prominent authors to opt out of the settlement to pursue independent lawsuits. Out of hundreds of thousands of class members, only 350 successfully opted out before the cutoff.
Lastly, the settlement also requires that Anthropic destroy the core library of pirated works it created, giving authors a clean slate to ward off future unauthorized usage.
