Anthropic agrees to $1.5B settlement in AI copyright case

Anthropic has agreed to pay $1.5 billion to settle a major copyright lawsuit brought by a group of authors who accused the company of using pirated books to train its AI models. The deal, if approved, would represent the largest publicly reported copyright recovery on record. The case centered on claims that Anthropic downloaded and exploited works obtained from online repositories such as Library Genesis and Pirate Library Mirror. Authors Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson led the lawsuit, arguing that their books were used without permission. As part of the settlement, Anthropic will pay about $3,000 per book plus interest and destroy datasets containing the contested material. Earlier this year, a judge ruled that Anthropic’s model training methods fell under the legal principle of “fair use.” However, the court allowed the case to proceed to trial to determine whether sourcing from pirated databases constituted copyright infringement. The settlement avoids that trial and closes what had become a closely watched legal battle in the AI industry. Justin Nelson, attorney for the plaintiffs, called the resolution a “powerful message” against taking copyrighted works from illegal sources. For Anthropic, the deal allows it to move past legacy claims while maintaining its position that its training practices are lawful. Aparna Sridhar, the company’s deputy general counsel, said the firm remains committed to developing safe AI that advances research and problem-solving. The lawsuit drew attention across tech and media circles as companies navigate the legal uncertainties around AI training data. While recent rulings in Anthropic’s case and a similar one involving Meta have bolstered confidence in current industry practices, experts warn that challenges remain. Pending cases include The New York Times v. OpenAI, Disney v. Midjourney, and a recent suit by Japanese media companies against Perplexity. Some legal analysts say these outcomes may weaken creators’ control over how their works are used. “Copyright has long protected not just profit, but choice,” attorney Irina Tsukerman noted. “Now, that control is slipping away.”
