What’s independently established: Anthropic ran a program called Project Panama, revealed in unsealed court documents, in which it bought millions of physical books, sliced off their spines and destructively scanned them for training data — reporting that led to a $1.5 billion author settlement, per the Washington Post. What’s not established: that the current wave of bulk secondhand orders described by the Guardian on August 15, 2026 — hitting shops from Northumberland to Claregalway to Bath — is coming from AI companies at all. That link is entirely inference, built by booksellers noticing thematically incoherent orders and matching aliases to a single Heathrow-area freight postcode.

The pricing detail is the tell worth watching. One anonymous UK bookseller told the Guardian buyers paid “top whack” on 6,000 books since January without seeking bulk discounts, and Barter Books moved hundreds of titles to three buyers for roughly £4,000. That is not how a recycler or a reseller behaves; it’s how a buyer behaves when the marginal cost of an individual book is irrelevant next to the value of unpolluted, pre-2022 text.

> The only confirmed price tag in this market remains Anthropic’s — tens of millions of dollars, per the Washington Post, folded into a $1.5 billion settlement — which dwarfs anything so far traced to the Heathrow warehouses.

Every named intermediary has denied direct involvement. ISBNdb, the metadata firm 404 Media flagged for touting “the world’s best AI training data is sitting on a shelf,” says the page was a shelved “test of market interest” and it has never bought, scanned or sold a book. Zoom Books, cited by multiple sellers including Bath’s BookLovers, calls itself a recycler and has denied the AI-sourcing claim to Swiss broadcaster SRF. Anthropic says none of its acquisition programs target rare or antiquarian books — a carefully scoped denial that leaves ordinary out-of-print nonfiction, exactly what The Atlantic found booksellers are actually shipping, untouched.

Validating the claim requires tracing money and freight, not vibes: subpoenaed shipping manifests or financial records linking the Heathrow postcode to a named AI lab or its contractors, a court filing in a future copyright suit naming a current buyer, or an actual on-the-record admission from a frontier lab that it is running a live secondhand-book procurement pipeline. Until one of those appears, this is a well-documented pattern of demand with an unconfirmed buyer — and for the data market, that ambiguity is itself informative: whoever is buying wants anonymity badly enough to route through freight warehouses and opaque aliases, which is its own kind of price signal.

> It's disrupting the secondhand bookselling business because this isn't typical for the trade. It appears to be either a human or a machine dipping into the sandbox of secondhand books and what they are buying makes no sense in terms of the wider trends in the market.
