Earlier this week the chatter around Anthropic's IPO was whether bankers would push pricing above the filed range and take the valuation past $1.5 trillion. That isn't what the filing shows. The proposed range is still $70-78 for 825 million Class A shares.

At the top end, that means about $64.35 billion in gross proceeds, part of which goes to selling shareholders, and a fully diluted valuation of up to $1.4 trillion. The WSJ puts the range at roughly $1.26 trillion to $1.41 trillion, with a midpoint around $1.33 trillion. Final pricing hasn't happened yet.

Demand doesn't look like the constraint. IPOX, citing Reuters, says order books were around six times the shares on offer as of Thursday. Nvidia, Alphabet, Microsoft and Micron are reported as buyers in a separate $26 billion private placement of non-voting Class N shares at the IPO price, tied to the offering. Trading is targeted for November 19 under ANT.

The detail I keep coming back to is the retail allocation. Anthropic's filing says up to 20% of IPO shares, depending on demand. That's roughly $12.9 billion at the top of the range, compared with a typical 5-10%. You can read that as broadening access to one of the most watched companies in AI. You can also read it as a lot of individual investors buying in at a trillion-plus starting point.

Jay Ritter's work is worth keeping in mind here. Most IPOs since 1975 have produced negative total returns for buyers. Strong books before day one tell you about demand. They say less about what the stock does from a $1.3 trillion base, and that's the question I'd want answered before buying.
