Anthropic files for an IPO at a $965B valuation while the music publishers' case rolls on

Anthropic has started the walk toward the public market. The AI company told the world it filed a confidential draft registration statement with the Securities and Exchange Commission for a proposed IPO. The number of shares and the price are not set yet.

For the music business, the headline is not the paperwork. It is the size of the war chest behind a company the industry is still suing.

A bigger war chest, days after a $65B raise

The filing landed days after Anthropic closed a $65 billion round that pushed its valuation to $965 billion. That figure put it ahead of OpenAI, which said it was worth $852 billion in March.

Anthropic also said its run-rate revenue crossed $47 billion this month. The IPO step keeps its options open without locking in a date.

This gives us the option to go public after the SEC completes its review. The proposed initial public offering will depend on market conditions and other factors.

The music case has not gone away

Anthropic is not a music company, but it sits inside a music fight. A group of major music publishers sued it over copyrighted lyrics used to train its Claude models.

The legal picture is mixed. Anthropic recently won the dismissal of a vicarious-liability claim. A separate claim, over how the company acquired the data it trained on, is still live.

A company this well funded can litigate for years, settle on its own terms, or license at a price that barely registers on its balance sheet. The publishers know that. The IPO filing is a reminder that the resources on the AI side of these cases keep growing while the rulings trickle out.
