Anthropic's S-1: the AI lab that became a business

For the AI Investment Brief, the team at Exponential View has distilled the S-1 into 39 charts, to help you see where the revenue comes from, where the compute goes and whether the numbers add up. I think Anthropic has crossed from lab to business: its revenue has grown roughly 31x since early 2025 while its compute costs have grown about 6x, and well over half the Fortune 500 now pays Anthropic. What the S-1 leaves open is duration: about 12 weeks of contracted revenue set against more than 12 years of signed compute, a mismatch the filing itself acknowledges.
In this live breakdown of the S-1, I discuss:

00:00 Is AI a real business?
02:00 The P&L: revenue outrunning compute
04:06 Why the customer-concentration worry was overblown
05:39 Half the Fortune 500 is already paying
08:14 New models drive the revenue
12:20 Scale is paying off: revenue 31x, compute 6x
13:52 Where a dollar of revenue goes
16:20 "Irresponsibly large" compute bets
17:30 12 weeks of revenue, 12 years of compute
18:54 Can Anthropic pay for its compute?
20:36 Values over profit maximization
21:39 Who controls Anthropic: Class F shares
23:00 "One of the seminal moments in human history"
24:11 Q&A: why most compute goes to training
26:37 Q&A: is the AI race just a race for capital?
A note on the numbers: at 17:56 I mention $587bn of compute commitments. That is the figure on June 30, 2026, the end of Q2 and the last date the S-1 reports in full. About $400bn of it can’t be cancelled. Deals signed in Q3 have since taken the total to roughly $775bn.
