A widely shared analysis of Anthropic's compute deal with IREN argues the customer name matters less than the price and compute type. Anthropic is buying capacity at a frantic pace, so IREN is unsurprising — what matters is deal structure.

The breakdown tiers Anthropic's deals: subleasing via Hut 8 (352MW and 245MW, with Fluidstack as counterparty) at annualized $1.86–1.90M per MW-year, the very low end; and direct leases like TeraWulf's 401MW 20-year deal. The poster adds that among owned-and-operated AI factories, IREN's closest comparison is xAI.
