Anthropic, the AI company behind the Claude large language model, has warned investors that any sale or transfer of its shares that has not received board approval is void and will not be recognised on its books.
Anthropic Warns Tokenized Stocks Are Void amid Booming Trade in Pre-IPO Tokens

The warning, first published on Anthropic's support page in February and updated 12 May, states that the company does not permit special purpose vehicles to acquire its stock and that transfers to such structures are void under its bylaws, as the market for tokenized pre-IPO exposure to private technology companies booms.
"Any third party claiming to sell Anthropic shares to the general public - whether through direct sales, forward contracts, tokenized securities, or other mechanisms - is likely either engaged in fraud or offering an investment that may have no value due to our transfer restrictions," the company wrote.
The notice comes as a tokenized Anthropic product on PreStocks, a crypto platform offering synthetic pre-IPO exposure, showed an implied valuation of approximately $1.5tn for the company as of 12 May, despite the platform holding around $23mn in total assets.
The ANTHROPIC token was trading at $962.18 as of 12:15 UTC, with a market capitalisation of $9.24mn, 3,679 holders and 24-hour trading volume of $6.1mn, equivalent to just over 66% of its total market cap, according to CoinMarketCap data.
Synthetic exposure vs share transfer
The pre-IPO token market encompasses a range of structures with materially different legal implications. Some products are synthetic perpetuals where no underlying shares are held, and traders take positions tied to a reference price derived from a private company's implied valuation.
Those instruments may not directly violate transfer restrictions because no shares change hands. Products structured through SPVs or secondary market holdings, where the claim is closer to actual equity exposure, run foul of the restrictions private companies impose on who may hold interests in their stock.
PreStocks' terms of service state that buyers receive no equity or shareholder rights in the underlying company, only economic exposure tied to reserve backing, without specifying the exact structure behind the Anthropic-linked token. Anthropic's warning makes clear it regards any such structure as potentially invalid regardless of how it is presented.
Valuation risk for private companies
Beyond the legal question, Anthropic's notice highlights a secondary risk posed by tokenized pre-IPO markets to private companies.
Speculative token prices on platforms with limited liquidity can generate implied valuations that shape investor expectations and media narratives beyond the company's control.
Anthropic, which raises capital through negotiated funding rounds rather than public markets, has not disclosed its most recent internal valuation. The company encouraged anyone who receives unsolicited messages offering access to its shares to exercise extreme caution, and directed concerns to its dedicated equity alerts inbox.
