Amazon set to be the biggest winner from Anthropic's IPO

Anthropic's IPO filing shows no venture firm holds the 5% stake needed to appear among its principal stockholders, unusual for a tech listing. At a $965 billion private valuation, Menlo Ventures' roughly $14 billion position is only about 1.5%. Amazon, which structured much of its investment as convertible notes that turn into shares at IPO, looks set to be the biggest beneficiary.
