What Happened
TeraWulf announced a landmark AI infrastructure deal with Anthropic on Monday, sending its stock up nearly 14%. The 20-year lease covers a 401 MW data center campus in Kentucky, expected to generate roughly $19 billion in revenue. Simultaneously, TeraWulf sold its 50.1% stake in a Texas data center joint venture for $450 million, crystallizing gains at a premium. The news ignited a rally across Bitcoin mining equities, with IREN, Hut 8, and Cipher Digital all posting double-digit gains.
The Numbers
The Anthropic deal is structured as a 20-year lease at TeraWulf's Justified Data site, with the first phase coming online in H2 2027 and full 401 MW capacity targeted by early 2028. The projected $19 billion revenue stream dwarfs TeraWulf's current market cap. The $450 million Texas stake sale monetizes invested capital at a premium. On the day, WULF gained 14%, while peers surged: IREN +13%, Hut 8 +12%, and Cipher +11%.
Why It Happened
AI compute demand is exploding, and Anthropic—creator of Claude—is racing to secure long-term power capacity. TeraWulf, originally a pure-play Bitcoin miner, began pivoting toward AI infrastructure in early 2025, betting that its energy assets and data center expertise could capture higher-margin AI workloads. The deal validates that strategy, proving Bitcoin miners can diversify into AI hosting without abandoning crypto.
Broader Impact
The rally extended far beyond TeraWulf. Bitcoin miners with available energy capacity and data center footprints are now seen as AI proxy plays. The market is rewarding companies that can bridge the gap between energy generation and AI compute. This could accelerate capital inflows into the sector, as miners repurpose assets for dual-use infrastructure.
What to Watch Next
- Phase one construction milestones at the Hawesville site, with first power delivery expected in H2 2027.
- Additional AI lease agreements from other miners as landlords compete for hyperscaler tenants.
- How TeraWulf's credit rating and financing evolve to support the massive buildout.
