Wu Shuo learned that, according to SolanaFloor disclosures, Anthropic PreStocks on Solana fell by 45% over the past 24 hours, with the implied market value dropping from approximately $1.4 trillion to approximately $762 billion—erasing about $638 billion in value. Previously, Anthropic issued an investor warning stating that private equity sales, transfers, or related interest arrangements without the company’s approval—including indirect exposure provided in forms such as “tokenized securities,” forward contracts, or SPVs—may be invalid, and the company will not recognize holders’ interests in such tokenized shares on the shareholder register. Anthropic also explicitly stated that SPVs are not allowed to acquire its stock. Products such as PreStocks typically only provide economic exposure linked to the valuation of private companies, and do not mean that holders own Anthropic equity or have shareholder rights.
