Anthropic's valuation on secondary market platforms has surged to approximately $1.2 trillion, marking a 550% increase year-over-year, according to Business Insider. This valuation surpasses OpenAI's current valuation of around $908 billion. Despite the high valuation, Anthropic has not yet gone public, limiting most investors to acquiring shares through secondary market transactions involving employees or early shareholders. Many of these transactions are structured as special purpose vehicles (SPVs). The company has issued warnings on its official website against unauthorized stock resales and potential scams, advising investors to "invest at your own risk." Due to the soaring share prices and increased scrutiny, actual tradable liquidity remains extremely low, with buy orders significantly outnumbering sell orders, making completed trades rare.
