Jim Cramer backs IREN as AI compute landlord; TeraWulf lands $19 billion（約3兆円） Anthropic deal

Jim Cramer's segment on Mad Money positioned a cohort of smaller compute operators—IREN, Hut 8, Cipher Digital, TeraWulf, Bitdeer Technologies, and Core Scientific—as a distinct investment category occupying the space between traditional hyperscale cloud providers (full-stack offerings) and real-estate colocation services. These companies, often spun from cryptocurrency mining or power infrastructure backgrounds, have found a profitable niche by leasing compute capacity and infrastructure without necessarily offering complete cloud service suites. The segment underscores a structural shift: major AI firms like Anthropic are willing to commit substantial capital (as shown by TeraWulf's $19 billion（約3兆円） agreement) to secure long-term compute supply from independent operators rather than relying solely on in-house or mega-vendor infrastructure. Cramer's specific mention that IREN is "growing like a weed" and that spare compute "someone like Anthropic will eagerly snap it up" reflects a view that these intermediate players are well-positioned to benefit from the AI industry's ongoing compute demands and may also present takeover targets for larger acquirers.
