Anthropic Bans Unauthorized Share Platforms, Closes Doors to SPV Purchases

Anthropic issued a stern warning last week about unauthorized secondary market transactions, naming eight firms and explicitly prohibiting investors from buying shares through special purpose vehicles. The crackdown prompted sharp reactions from trading platforms and hedge funds, with one closed-end fund reporting a 25% decline in its Anthropic holdings’ share value in the days following the announcement. According to Bloomberg, Anthropic is pursuing additional funding at a valuation exceeding $900 billion.
