Anthropic just drew a line in the sand. The AI company issued a warning on May 12 declaring that any sale or transfer of its stock without explicit Board of Directors approval is void and will not be recognized by the company.
The move comes as Anthropic’s valuation has ballooned in secondary markets, with estimates nearing $1 trillion.
What Anthropic is actually saying
The company’s position is blunt: if you bought Anthropic stock through a channel the Board didn’t approve, you don’t own Anthropic stock. You own a receipt from someone who took your money.
Anthropic specifically called out several platforms it considers unauthorized traders, including Open Door Partners and Unicorns Exchange. The company also flagged Special Purpose Vehicles, tokenized securities, and direct public sales as prohibited methods of transferring shares without Board sign-off.
SPVs are pooled investment structures that let multiple smaller investors collectively buy a stake in a private company. Tokenized securities represent ownership claims minted on a blockchain. Both sound sophisticated. Neither matters if the underlying transfer was never approved.
The company urged investors to watch for red flags: unsolicited contacts, claims of exclusive access to shares, and high-pressure sales tactics.
The pre-IPO scam problem is getting worse
Pre-IPO fraud schemes leveraging crypto channels have increased 40% year-on-year, according to SEC data. The playbook is predictable: scammers identify a hot private company, create convincing-looking investment vehicles, and sell “shares” to retail investors who have no way to verify the legitimacy of the offering.
Tokenization has made this easier to pull off. Minting a token that claims to represent equity in a private company requires approximately zero cooperation from that company.
Anthropic, which builds the Claude family of AI models, has raised billions in venture funding and sits near the top of the generative AI hierarchy alongside OpenAI. Founded in 2021 by former OpenAI researchers, the company attracted over $18 billion in funding from major investors like Amazon and Google, with its valuation climbing from $4 billion in 2023 to projections exceeding $1 trillion by early 2026.
Why crypto investors should pay attention
Anthropic’s stance is a reminder that the company issuing the stock gets to decide whether a transfer is valid. A token on Ethereum doesn’t override a transfer restriction in a shareholders’ agreement. Legitimate tokenized securities platforms work with issuing companies to ensure compliance. The unauthorized versions skip that step entirely, which is what makes them unauthorized. Investors who purchase through these channels face a specific risk: the company may simply refuse to recognize their ownership, ever.
The 40% year-on-year increase in pre-IPO fraud via crypto channels also gives regulators fresh ammunition. The SEC has been increasingly vocal about treating tokenized securities as securities.
Investors eyeing any pre-IPO opportunity should verify directly with the issuing company that a proposed transfer will be recognized. If the seller can’t provide evidence of Board approval, the investment is functionally worthless regardless of what shows up in your wallet or brokerage account.
