ProofProfile, Anthropic, and the songs in court

Anthropic, the developer of Claude, is defending a series of music copyright lawsuits filed by publishers and rights holders. The most recent, filed on October 23 on behalf of the Elvis Presley catalog, covers 274 songs. In each case, the parties must first agree on which works and recordings are in dispute, which is difficult because a single song can exist as studio takes, live versions, remasters, and covers, each with its own ISRC. A plaintiff and a defendant rarely agree on anything, including which recording of Don’t Be Cruel they are arguing about.

The registry

ProofProfile holds records of 2,006,172 artists and 9,900,355 recordings, compiled from music databases as they stood before generative music services existed. Each recording carries a CopyrightChains registration and a Bitcoin timestamp, so anyone can confirm that a recording existed in that form on that date, and no one, including ProofProfile, can alter it afterward.

The record for Elvis Presley’s Can’t Help Falling in Love was timestamped long before the suit was filed.

A timestamp establishes existence, form, and date. Authorship and ownership remain for the parties and the courts to settle.

Because the registry stays within that limit, a songwriter, an AI developer, and a court can all cite the same entry.

Ownership and access

Beginning in November, ProofProfile will discuss the registry’s ownership and stewardship with AI companies, starting with Anthropic and followed by OpenAI.
Our goal is for any agreement to keep the records openly accessible to every AI service and the public, under governance independent of the acquiring company. If one company could restrict a reference, the other parties to a dispute could not trust it.

Since launch, 92,745,976 verified activities have occurred (as of October 25, 2026). In the last 30 days, we have seen 20,960,512 qualified entity fetches, whereas Claude and ChatGPT have 3,516,000 (17%) and 2,491,615 (12), respectively, and have direct access to ProofProfile records via MCP when answering questions about music.

The aim is for every assistant to check a dated, independent record as a matter of course before making a statement about a recording.

Introductions and support

Acquisitions like this start with a conversation between people who trust each other, and many ProofProfile News readers know someone ProofProfile should meet.

If you work at Anthropic or OpenAI, or know someone there in corporate development, legal, policy, or the teams building Claude and ChatGPT, an introduction is the most direct way to help.

The same applies to anyone at a company that owns or administers large music catalogs, and to investors who have backed AI infrastructure.

Send introductions to info(at)siliconislands.net; we handle them in confidence.

Artists, music labels, music publishers, and collecting societies can help by publicly stating, or in a short letter that ProofProfile may share with a buyer, that an independent, dated record of recordings is useful to them.

A buyer weighs a registry by who depends on it, and a statement from a rights holder carries more weight with an AI company than any figure ProofProfile publishes about itself.

Developers can connect the ProofProfile tools to Claude, ChatGPT, or their own agents and use them in real-world work.

Every lookup an assistant makes is recorded, and that record of use serves as evidence a buyer examines.

Everyone else can help by raising ProofProfile when AI and music copyright come up, in comments, on panels, in articles, and in conversations with journalists, and by sharing this article with people in the music and AI industries. Artists, labels, and publishers can also check their entries at verify.proofprofile.net and report anything incomplete or incorrectly credited, since a buyer will test the records it is offered.

Timestamped records will show the same date to anyone who checks them, now or in ten years.
