Anthropic's S-1 is a new milestone in Big Tech's sprawling and lofty promises to Wall Street

To some extent, Anthropic suggests in a letter at the top of its S-1 filing, you have to just believe

But its sweeping language and sheer volume — including 94 pages of risk factors — is a sometimes overwhelming collision of AI industry rhetoric and a hard financial pitch. Out-of-this-world promises are integral to Anthropic's survival as a company . That doesn't make reading the S-1 any less surreal
