Anthropic has declared secondary market stock trading invalid; this policy covers tokenized securities.

CoinFeed reported on May 12 that, according to Cryptopolitan, Anthropic has declared all unauthorized secondary market stock transactions invalid, a move that could trigger significant litigation under Delaware law. The company issued a notice on its Claude Help Center stating that any sale or transfer of shares without the express approval of its board of directors is invalid and will not be recognized. This policy covers direct sales, beneficial interests, forward contracts, special purpose vehicles, and tokenized securities. Secondary trading platforms such as Forge Global and Hiive have been listed as unauthorized channels. Previously, secondary platforms valued Anthropic at approximately $1 trillion, exceeding its $380 billion valuation in its most recent major funding round.
