Anthropic and OpenAI PreStocks Crash 38-46% Amid Company Warnings on Unauthorized Transfers

According to reports, Anthropic and OpenAI have issued warnings against unauthorized equity transfers, including transactions via SPV, tokenized instruments, or forward contracts, stating such trades may be invalid and unrecognized by the companies. The cautionary statements triggered sharp declines in related PreStocks tokens on Solana, with Anthropic PreStocks dropping approximately 38% and OpenAI PreStocks falling about 46%.

Both firms emphasized that their common and preferred shares are subject to strict transfer restrictions, and transactions without board approval will not receive shareholder rights recognition. OpenAI further warned that such transactions may violate U.S. securities laws, leaving buyers without any actual economic benefit.
