Tokenized equity instruments representing private artificial intelligence companies experienced significant price declines this week following official warnings from both firms regarding unauthorized share transfers. Anthropic and OpenAI each released statements clarifying that their equity holdings face stringent transfer limitations under existing corporate governance rules. Market participants responded swiftly, driving token valuations downward across Solana-based platforms.
Anthropic Issues Public Warning on Unauthorized Equity Transactions
Anthropic released an official notice targeting transfers conducted through special-purpose vehicles and tokenized financial products. According to the statement, all preferred and common stock transfers require explicit board authorization. The company emphasized that any transaction lacking proper approval holds no validity and receives no acknowledgment in official corporate records.
The AI firm explicitly identified three platforms—Open Door Partners, Hiive, and Forge—as operating without authorization to facilitate trades of its equity. Anthropic stressed that purchasers participating in such transactions may forfeit stockholder privileges entirely. Board approval remains mandatory for any transfer to maintain legal standing.
Data from CoinGecko shows Anthropic PreStocks on Solana fell approximately 38% from late Tuesday onward. The tokenized instrument traded around $879 with an estimated market capitalization near $8.3 million. These metrics reflect secondary market activity for the tokenized product rather than official company valuation.
PreStock instruments attempt to mirror implied valuations of private companies ahead of potential public offerings. These companies maintain no formal endorsement of such products. Market pricing therefore responds directly to official company communications and speculative trading patterns.
Anthropic’s notice reiterated that corporate governance documents restrict all ownership transfers absent explicit consent. The company clarified that this limitation extends to forward contracts, tokenized structures, and similar financial arrangements. Any transactions bypassing this approval process carry zero recognition in official stockholder documentation.
The warning appeared earlier in the week and generated immediate market reactions. The company made clear that only properly authorized transactions receive formal acknowledgment.
OpenAI PreStocks Decline Following Securities Compliance Alert
OpenAI issued a parallel warning addressing unauthorized equity trading activity. The company’s statement highlighted that existing shareholder agreements impose strict limitations on all share transfers. OpenAI cautioned that transactions conducted outside approved channels potentially breach U.S. securities regulations.
According to OpenAI’s notice, unauthorized trades may result in invalid underlying equity positions. The company specified that such transactions potentially deliver zero economic benefit to purchasers. OpenAI maintains that it recognizes only those transfers receiving proper authorization.
CoinGecko data indicates OpenAI PreStocks decreased approximately 46% throughout the same period. The token reached a price near $1,080 with a market capitalization around $2.2 million. These figures represent activity solely within the tokenized instrument market.
The company specified that its warning encompasses sales through SPVs and tokenized vehicles. All equity transfers demand proper authorization according to OpenAI’s position. Absent such approval, the company will decline to record any transaction in official shareholder records.
Both artificial intelligence firms published their respective statements during the same week. Each announcement centered on existing transfer restrictions and regulatory compliance obligations. Token markets adjusted valuations rapidly in response to these official disclosures.
