The people most exposed to Anthropic's IPO math are retail buyers who read "$1.4 trillion" and "$64 billion" as the same story. Those figures measure different things, and I still lean that a richer price makes year one harder to live up to.

  • The November 10 amended S-1 sets a preliminary $70-78 range for 825 million Class A shares. 801.35 million are new shares from Anthropic and 23.65 million come from existing holders, so about $62.5B of the roughly $64.35B top end goes to the company.
  • About $1.4T is the fully diluted value at the high end. Reports citing the filing put it near $1T on shares outstanding, so the valuation depends on which share count you use.
  • A separate $26B private placement of non-voting shares to seven named tech investors is conditional on the IPO closing.
  • The FT reported, and Bloomberg relayed, that bankers are weighing $1.5T or more on demand. ANT is the proposed Nasdaq ticker, with trading expected November 19.

My read is a pop at debut and a fade within about a year, unless revenue and profit grow fast enough to justify whichever valuation it lands on. I could be wrong if that growth shows up. Which number will you be anchoring to on the 19th?
