Anthropic Warns Investors of Unauthorized Share Trading on Secondary Platforms

Anthropic this week updated its website to warn investors that a slew of private and secondary investment platforms are not authorized to offer its shares. The named platforms include Open Doors Partners, Unicorns Exchange, Pachamama Capital, Lionheart Ventures, Hiive, Forge Global, Sydecar, and Upmarket. Anthropic stated that any transactions through these platforms are void and unrecognized. This warning comes amid a rise in demand for AI company shares on secondary markets, with Anthropic, potentially raising funds at a $900 billion valuation, being particularly sought after. Some platforms offer exposure through tokenized securities, SPVs, or derivative contracts like pre-IPO perpetual futures. Anthropic emphasized its transfer restrictions, invalidating any unauthorized share sales. The move highlights risks in secondary market investments, especially with crypto companies like OKX offering AI company exposure products, sometimes based on liquidated holdings from bankruptcies like FTX.
