Solana-based PreStocks tied to private AI companies fell sharply this week after both firms warned against unauthorized equity transfers. Anthropic and OpenAI said their shares carry strict limits under corporate bylaws. Consequently, token prices dropped as traders reacted to the statements.
Anthropic issued a public notice that addressed transfers through special-purpose vehicles and tokenized instruments. The company said its preferred and common shares require board approval for any transfer. It stated that any unapproved sale is void and unrecognized on its books.

The company named Open Door Partners, Hiive, and Forge as unauthorized platforms for trading its shares. Anthropic said buyers in such transactions may not receive stockholder rights. It added that the board must approve any transfer for it to remain valid.
Anthropic PreStocks on Solana dropped about 38% since late Tuesday, according to CoinGecko data. The token traded near $879 with a market cap of about $8.3 million. These figures reflect activity in the tokenized instrument rather than the company’s official valuation.
PreStocks aim to track implied private company values before a potential public listing. However, the companies do not endorse these instruments. Therefore, market prices respond directly to issuer statements and trading activity.
Anthropic stressed that its corporate bylaws restrict ownership transfers without consent. It said any transfer through forward contracts or tokenized structures falls under those limits. The notice underscored that unapproved trades hold no standing in company records.
The company published the warning earlier this week. It made clear that only board-approved transactions carry recognition. The statement prompted swift reactions in related token markets.
OpenAI released a similar warning about unauthorized equity transactions. The company said its shares carry strict transfer limits under existing agreements. It warned that transactions outside approved channels may violate U.S. securities laws.
OpenAI stated that unauthorized trades could result in invalid underlying equity. It added that such transactions may carry no economic value to buyers. The company emphasized that it does not recognize unapproved transfers.
OpenAI PreStocks declined roughly 46% over the same period, CoinGecko reported. The token traded near $1,080 with a market cap of about $2.2 million. These figures represent movements in the tokenized instrument only.
The company clarified that its notice applies to sales through SPVs and tokenized vehicles. It said any equity transfer requires proper authorization. Without approval, the company will not record the transaction.
Both firms issued their statements earlier this week. The announcements focused on transfer restrictions and compliance requirements. Token prices adjusted quickly following the disclosures.
