TeraWulf's stock climbed after the Bitcoin miner inked a 20-year infrastructure lease with Anthropic, the AI startup backed by Google and Amazon. The deal locks in long-term revenue from AI workloads running on TeraWulf's existing mining infrastructure.

Simultaneously, TeraWulf sold its majority stake in an AI data center joint venture, further diversifying away from pure Bitcoin mining operations. The moves reflect a broader pivot underway at major mining firms: idle or underutilized hash power now generates revenue from AI compute jobs.

The Anthropic lease carries a $19 billion valuation component, signaling substantial resource commitment from the AI firm. For TeraWulf, the arrangement provides predictable cash flows over two decades. Bitcoin miners have increasingly leaned on this strategy as network difficulty adjustments and hash price compression squeeze per-unit margins.

AI infrastructure leases offer miners several advantages. First, power draw remains constant whether equipment runs hash functions or AI training jobs. Second, lease payments often exceed what Bitcoin mining alone generates on a per-megawatt basis. Third, the arrangement hedges against Bitcoin price swings by introducing non-correlated revenue streams.

The JV stake sale reinforces TeraWulf's shift toward becoming an infrastructure landlord rather than just a mining operator. Selling majority control reduces operational complexity while extracting capital from the asset.

This mirrors moves by other public miners. Marathon Digital and Hut 8 have both pursued AI infrastructure partnerships. The trend accelerates as Nvidia chips, power availability, and thermal management become the actual scarce resources in data center markets. Bitcoin mining hardware represents a sunken cost miners can repurpose when market conditions warrant.

TeraWulf's announcement validates what miners discovered over the past 18 months: AI workloads pay better. The $19 billion valuation attached to the
