Anthropic's Dario Amodei flags compute as 'deepest business dilemma' ahead of Nov. 19 IPO

Amodei's comments come as Anthropic prepares for what could be the largest IPO in history. The company has already committed nearly $901 billion, mostly to compute and chips, with roughly $71 billion due by September 2027—a figure Bloomberg notes exceeds the market cap of about two-thirds of S&P 500 companies. This enormous commitment underscores the scale of the bet Anthropic is making on future demand for AI.

The timing of Amodei's warning is notable. Just days before the planned Nov. 19 IPO, he acknowledged the inherent uncertainty in predicting how AI progress will translate into economic value. This isn't the first time he has raised such concerns; in February 2026, he warned that being off by just one year on compute needs could mean bankruptcy. The IPO is intended to provide a financial cushion, giving Anthropic more room to maneuver between having too little and too much compute.

Despite the risks, Anthropic's revenue is growing rapidly, with an annualized run rate of $81 billion at the end of October, up from $71 billion in late September. The IPO, reportedly already about six times oversubscribed, will test whether investors share Amodei's cautious optimism—and his hope that AI will cure cancer and Alzheimer's within five to 15 years.
