I legitimately think Anthropic is worth $100B more than it was a week ago

A week ago I put out a first-day IPO market cap forecast for Anthropic with a reference point of $19B ARR. Then Anthropic announced their ARR had grown from $19B to $30B. I updated my forecast and now think Anthropic is worth at least $100B more than I did a week ago.

I'm still anchoring growth rate assumptions to how companies have historically scaled revenue, but if growth trends from the last four decades were to continue, this would imply a company growing faster than any company in history (~$10B in 2025 to ~$100B by 2027.) Previously, I thought OpenAI could achieve that. Now it looks like Anthropic is the company to do it, but with an even steeper revenue curve, given that they hit their first billion in ARR much later than OpenAI. Of course, it's difficult to figure out how much weight we should give to ridiculously outsized growth in the age of AI. If historical growth patterns no longer apply, then $643B is way too conservative. (Full updated forecast: https://futuresearch.ai/anthropic-30b-arr-ipo-valuation/)

The second implication of this week's news is IPO timing and whether the $30B number makes Anthropic list earlier than my original March 2027 date. Investor sentiment is hot now, and it's always risky to bet that growth will continue at this astounding rate. How much could waiting another year cost them?
