Nearly 120,000 authors and other copyright holders have filed claims to share in Anthropic’s US$1.5 billion class-action settlement over the unauthorized use of books in AI training, with claims covering 91% of more than 480,000 works, court filings in California show.

Anthropic, a US AI startup backed by Amazon and Alphabet, is due at a May 14 hearing, where a judge will decide whether to give final approval to what has been described as the largest settlement in a US copyright case.
