Anthropic's announced compute tops 11.5GW; full buildout could cost ~$120B a year

Tallying by Oguz Erkan suggests Anthropic has announced over 11.5GW of compute capacity, with only an estimated 1-2GW actually running today.
- Full buildout could cost roughly $115-120B per year
- If OpenAI scales similarly, the two companies' combined compute spend over five years could approach $1 trillion
The takeaway: with commitments this large, AI labs 'slowing down' voluntarily looks financially implausible.
