# Sony and Warner sue Anthropic for copyright

> Two of the largest music companies, Sony and Warner, have sued Anthropic, accusing it of using their songs' lyrics and compositions to train its Claude models without permission. It is at least the third major copyright suit the company has faced, and it pulls the music industry squarely into a fight that has so far centered on authors, artists, and news publishers. The publishers allege large-scale, unlicensed copying of protected compositions and are seeking statutory damages of up to $150,000 per work. Given how many songs are involved, that framing is what makes these cases existential rather than a cost of doing business, because the potential liability scales with the size of the training set. The stakes reach every frontier lab. The core question, whether training a model on copyrighted material is fair use or infringement, is still unsettled, and rulings against Anthropic could force the whole industry toward paid licensing deals with rightsholders. For musicians and labels, the suit is also a bid to make AI companies pay for the catalog they have quietly ingested.
