On October 18, 2023, Anthropic was sued by Concord, Universal, ABKCO, and other music publishers for, per the complaint, "systematic and widespread infringement of their copyrighted song lyrics."[107][108][109] They alleged that the company used copyrighted material without permission in the form of song lyrics.[110] The plaintiffs asked for up to $150,000 for each work infringed upon by Anthropic, citing infringement of copyright laws.[110] In the lawsuit, the plaintiffs support their allegations of copyright violations by citing several examples of Anthropic's Claude model outputting copied lyrics from songs such as Katy Perry's "Roar" and Gloria Gaynor's "I Will Survive".[110] Additionally, the plaintiffs alleged that even given some prompts that did not directly state a song name, the model responded with modified lyrics based on original work.[110]

On January 16, 2024, Anthropic claimed that the music publishers were not unreasonably harmed and that the examples noted by plaintiffs were merely bugs.[111]

In August 2024, a class-action lawsuit was filed against Anthropic in California for alleged copyright infringement. The suit claims Anthropic fed its LLMs with pirated copies of the authors' work, including from participants Kirk Wallace Johnson, Andrea Bartz, and Charles Graeber.[112] On June 23, 2025, the United States District Court for the Northern District of California granted summary judgment for Anthropic that the use of digital copies of the plaintiffs' works (inter alia) for the purpose of training Anthropic's LLMs was a fair use. But it found that Anthropic had used millions of pirated library copies and that such use of pirated copies could not be a fair use. Therefore the case was ordered to go to trial on the pirated copies used to create Anthropic's central library and the resulting damages.[113] In September 2025, Anthropic agreed to pay authors $1.5 billion to settle the case, amounting to $3,000 per book plus interest. The proposed settlement, pending judge's approval, stands as the largest copyright resolution in U.S. history.[114][115]

In June 2025, Reddit sued Anthropic for "unlawful and unfair business acts", alleging that Anthropic was in violation of Reddit's user agreement by training its models on users' personal data without their consent.[116][117]
