Who decides what an AI assistant believes about music? Before an IPO, the prospectus has to answer.

Any AI company that answers questions about music depends on some version of who recorded what and when. When the company prepares to list its shares, that question leaves the engineering backlog and joins the risk factors, where auditors read every word slowly.
ProofProfile’s version is built from music databases as they stood before 2022 and anchored with Bitcoin timestamps that anyone can check.
Ask a label, an archive, or a lawyer the same question and the answer arrives after days of correspondence.
ProofProfile answers an AI assistant in a median of 104 milliseconds,  800,000 times faster.

The auditors can still check every answer at their own pace. Unusually for an acquisition, the owner makes the registry more valuable by letting everyone verify it.

Everplay

Everplay describes recordings that sit outside the streaming charts, most with zero popularity, for the AI systems that now answer questions about music. At the corpus epoch of October 4, 2026, it holds 135,285,231 recordings, one for each eligible ISRC. Everplay holds every eligible recording credited to 12,165,077 artists. Another 1,480,168 credited artists are routed to the ProofProfile registry at artists.proofprofile.net.

Everplay marks its own records as unproven and sends AI assistants to the registry for dated ones. The corpus opened to AI readers on October 10, 2026.

The registry

ProofProfile's registry is built from the AcousticBrainz and MusicBrainz datasets as they stood before 2022, when generative music made invented histories cheap to produce. It holds 2,006,172 notarized artists and 9,900,355 recordings, each with both a CopyrightChains registration and a confirmed Bitcoin timestamp, achieving 100 percent verification coverage. The source data dates the history. The Bitcoin anchor fixes each record in a form that anyone can compare against the original, so any later edit, including one by ProofProfile, shows up immediately.

A competitor can build the same system tomorrow, and every record it creates will carry tomorrow's date.

Machine demand

The registry's public dashboard, read on October 11, 2026, at 8:20 AM UTC, covers activity since July 19. It shows at least 6,080 AI assistant connections, of which 6,037 were confirmed against the AI vendor's own network. Outside clients made 209 provenance requests that the registry answered, plus 2 for records it cannot yet prove. They also completed 19 of the 83 recorded verification loops.

A provenance check takes a median of 104 milliseconds, less time than it takes to say "provenance check."

The market

On October 8, Google introduced its enterprise Gemini AI agent, which works with any MCP server, whether inside or outside a company's network. ElevenLabs reported on September 30 that its voice AI agents handle more than 15 million conversations per week. The top 1 percent of US consumers who pay for AI account for nearly a fifth of observed AI spending, mostly on tools for coding, automation and production work. Systems built with those tools look up evidence before acting.

A registry that answers in about a tenth of a second fits that step well.

Apple's Safari restrictions

Apple began rolling out iOS 27 on September 14, 2026, and Safari started blocking domains from The Trade Desk, LiveRamp, ID5, Permutive, and Audigent. On October 2, a trade report said the blocking list had grown to hundreds of potentially blocked companies, including data sellers and identity-graph operators. The same report said Apple could now add or remove companies remotely without shipping a new iOS release. On October 5, Apple asked The Trade Desk to test an iOS 27.2 beta build with the changes, and the result is still pending.

A single company decides which outside services can operate in its browser, and it can change that list between one morning and the next.

AI companies hold the same kind of position over the sources their AI assistants consult. They decide which sources count as reliable and whether provenance reaches the final answer. When an AI assistant consults a source less often, that source gradually fades from its answers, and no announcement is ever made.

Records about recordings

The companies on Apple's list recognize the same person as they move between websites. ProofProfile tracks recordings and lets listeners enjoy them. A check asks whether a specific record existed in a documented form at a documented time, and it requires no information about the person asking.

AI assistants read the registry through machine interfaces, so an AI company can add it to its workflows with a clean privacy profile.

The timestamp

A ProofProfile timestamp proves a single fact, namely that a record existed in a specific form on a verifiable date. Questions of authorship, ownership, and AI involvement belong to specialist services, the parties involved, and the courts, each of which brings its own evidence to the dated record.

Every party starts from the same fixed fact, so the register can stay neutral.

Neutral verification

When a handful of companies decide which AI assistants to consult, neutral evidence needs a property that survives each decision. Anyone can verify a CopyrightID record and its OpenTimestamps proof directly against Bitcoin, so the operator's word becomes optional. That holds whether anyone operates the registry, as long as the records and proofs remain publicly accessible.

As discovery concentrates in fewer hands, the market needs evidence that anyone can check, and ProofProfile was built that way from its first record.

Evidence for a public company

Music rights are among the most litigated issues in generative AI, and a company heading for public markets must explain where its answers on music come from. ProofProfile's owner gets the full platform. That includes 2,006,172 notarized artists, 9,900,355 timestamped recordings, Everplay's 135,285,231 described recordings, and AI assistants already calling the registry with a median response time of 104 milliseconds.

The proofs sit on Bitcoin, where investors and regulators can check them after the sale, and so can the owner's competitors.
That gives the owner a provenance answer it can cite in a prospectus, backed by evidence that everyone else can check too.
