Anthropic, the artificial intelligence company behind the Claude model, told the market this week that any unauthorized third-party purchases of tokenized shares of the company are void. The announcement sent the price of those tokenized shares tumbling 45% almost overnight. The crash is the latest reminder that tokenizing a company's equity without its consent carries real risks — and that regulators have yet to catch up.
What Anthropic said
In a statement posted to its corporate website on May 15, Anthropic said it had not authorized any tokenization of its shares and that any such offerings were made without the company's permission. The company warned that anyone who buys or sells these tokenized securities does so at their own risk, and that the underlying ownership claims are invalid. Anthropic did not name any specific platform or issuer behind the tokenized shares, but the warning was clear: these aren't real shares.
How the market reacted
The response was swift. Tokenized versions of Anthropic stock, which had been trading on decentralized exchanges and some unregulated platforms, lost nearly half their value within hours of the warning. The 45% selloff shows just how fragile demand is when the underlying asset is essentially a promise from a third party — not the company itself. One trader described the situation as a 'flight to the exit' as holders rushed to get out before the tokens became worthless.
This isn't just about one company. Unauthorized tokenization has been a recurring headache for private firms that aren't publicly traded but still have eager investors looking for exposure. Without the company's backing, these tokens are little more than speculative IOUs. The crash underscores the need for regulatory clarity: Are tokenized shares securities? Who enforces the rules when the issuer isn't the company itself? And what happens to investors who bought in good faith?
For now, the answer is grim. The value of those Anthropic tokenized shares is effectively zero if the company refuses to honor them. Exchanges that listed the tokens may face pressure to delist, and regulators could step in — but so far, none have. The episode is a cold reminder that in crypto, not everything that looks like a stock actually is one.
