Anthropic Signs Undisclosed Multiyear Cloud Deal With IREN
The gist
Anthropic is assembling a large volume of data center capacity across multiple partners, and the IREN deal shows it is drawing on bitcoin mining infrastructure operators to do so. Analysts put concrete revenue stakes on the speed of that buildout.
The full picture
Anthropic signed an unannounced multiyear cloud deal with IREN, an Australian-listed bitcoin miner, as reported by The Information. The dollar value and term of the agreement were not disclosed. The deal is part of Anthropic assembling roughly $530 billion in data center leases. Anthropic's infrastructure buildout relies increasingly on current and former bitcoin miners including Hut 8, TeraWulf, IREN, and Nscale. Analysts estimate that switching on a 245 MW site one month early would add more than $1.3 billion in monthly revenue, which explains the pressure on partners to deliver capacity quickly. IREN shares jumped overnight on the report before giving back some gains.
