Anthropic Warns Investors About Unauthorized Platforms Selling Shares

Huo Xing Finance reports that Anthropic updated its website this week to warn investors that multiple private and secondary market platforms are not authorized to facilitate the purchase or sale of its shares. The platforms named include Open Doors Partners, Unicorns Exchange, Pachamama Capital, Lionheart Ventures, Hiive (new offering), Forge Global (new offering), Sydecar, and Upmarket. Anthropic stated that any share sales or transfers offered by these companies are invalid and will not be recognized in the company’s records. The company emphasized that both its preferred and common shares are subject to transfer restrictions, and all transactions without board approval are void. It also explicitly prohibits the acquisition of its shares through special purpose vehicles (SPVs). Forge Global responded that it was incorrectly listed and is currently in communication with Anthropic to have its name removed; Sydecar stated that it only performs administrative functions and does not buy or sell securities. This announcement comes amid rumors that Anthropic is raising a new round of funding at a $900 billion valuation, with several secondary market brokers describing its shares as among the most difficult to obtain.
