Amodei calls compute Anthropic's 'deepest business dilemma'

Anthropic's IPO filing lists $900.9 billion in long-term compute commitments running through 2045, and at a livestreamed conversation with Jamie Dimon at JPMorgan's Manhattan headquarters, CEO Dario Amodei told the room this is the single hardest thing about running the company.

"Compute is the deepest business dilemma that the company faces," Amodei said, according to Bloomberg. "If you buy too much ... you can financially overextend yourself. If you buy too little, then you can't support inference for customers."

The way out, he said, is to err cheap. "The way we think about that is we actually tend to buy on the low side. We buy relatively little compute for relatively low cost ahead of time." If demand beats plan, Anthropic tops up on the spot market, which Amodei said "so far has always been available and which we believe will continue to be available." He compared the setup to an insurance policy.

The scale behind that framing is unusual. The S-1 shows about $451.6 billion of the $900.9 billion falling before 2030, $70.7 billion due by September 30, 2027, and compute costs hitting 48% of revenue in a single 2026 quarter. Amodei said he plans around something near the 10th percentile of growth, and told Dimon the company wants to "underpromise and overdeliver."

Anthropic is expected to price its offering Wednesday and begin trading Thursday, Nov. 19, with a $70-$78 per-share range that values the business at up to $1.4 trillion, below the roughly $2 trillion number floated in September. Chinese and Hong Kong investors were shut out of the book this week. The filing never names a backstop if that spot-market assumption breaks.
