Anthropic has soared to a $1.5 trillion valuation on secondary markets. Almost no one wants to sell.

Anthropic's secondary valuation has recently soared to $1.5 trillion, marking a 25% increase over the past month, even as competition intensifies from companies like OpenAI and China's Moonshot AI. Despite the high valuations, obtaining shares on the secondary market is described as incredibly difficult for investors, who are positioning themselves ahead of an expected IPO.
