Tokenized Anthropic and OpenAI PreStocks on Solana experienced significant declines after both artificial intelligence companies issued warnings about unauthorized equity transfers. According to reports from The Block, Anthropic PreStocks fell 38% and OpenAI PreStocks declined 46% following the corporate notices. The price drops reflect trading activity in the tokenized instruments rather than changes to the underlying private companies' official valuations.
In notices published earlier this week, both firms stated that their preferred and common stocks are subject to strict transfer restrictions under corporate bylaws. As reported by The Block, the restrictions apply to any attempted sales or transfers via special-purpose vehicles, tokenized instruments, or forward contracts. Anthropic listed several firms as unauthorized to buy or sell its shares, including Open Door Partners, Hiive, and Forge. The company stated that any transfer not approved by its board is void and would not be recognized on its books, meaning purported buyers may not receive stockholder rights.
According to CoinGecko data reported by The Block, Anthropic PreStocks dropped around 38% since late Tuesday to approximately $879, resulting in a market cap of about $8.3 million. OpenAI PreStocks plunged roughly 46% to $1,080 over the same period, with a market cap of approximately $2.2 million. The substantial price declines demonstrate the immediate market response to the corporate warnings about unauthorized equity transfers.
As reported by The Block, OpenAI issued a similar warning stating that unauthorized transactions may violate U.S. securities laws and could result in the invalidation of the underlying equity. The company added that such transactions could carry no economic value to buyers. PreStocks are tokenized instruments designed to track the implied value of private companies before a potential public listing, though they are not officially endorsed by the underlying companies.
